Abstract

The invention relates to a device for measuring the duration of telephone line utilization in a telephone terminal according to signals emitted from a telephone exchange. The device shows the duration of calls, the beginning and end of calls, the accumulated time and the number of calls made. The device can switch different equipment on and off depending on the signals emitted from the central exchange.

Description

^" Time Controller Device: Use of Telephone Line ^"

SECTOR OF THE TECHNIQUE TO WHICH THE INVENTION BELONGS

The invented device belongs to the Telecommunications Sector:

BACKGROUND OF THE INVENTION

The closest background I Invented Device are: The Electricity Meter and the water consumption meter (in terms of its function of contrasting with the charge), and the telephone usage meters.

BRIEF DESCRIPTION OF THE INVENTION

It differs greatly from other time meters, because they act according to what happens with the user's telephone equipment; instead, the invented device acts in accordance with what happens in the external Telephone System belonging to the City Telephone Company and its signals for each user in particular: on the basis of which it connects or disconnects circuits that can activate or disable any internal or external equipment.

With this invented device, the problem of EXACTLY measuring the duration of a call is solved: from when the person called is picked up, until that same person hangs up or the person who has called hangs up. The user must know the REAL service consumed, so it controls up to seconds.

This time of each call is automatically accumulated in a specially modified clock to measure long duration events.

In addition, the invented device is: reliable, easy to build, low cost, easy to install, automatic, maintenance free and easy to read. DESCRIPTION OF THE INVENTION

EXTERNAL PRESENTATION

The presentation is easy to modify as the invented device is presented as a clock that can be adapted to any support housing.

INSTALLATION

It is installed by connecting the two terminals of the invented device to the two poles of the telephone line, taking into account the polarity and before any particular telephone exchange.

THE CLOCKS

The Clocks that the invented device uses to measure time can be: any type of timer, with or without its own energy source. Or they can be the analog clocks (here called ^" Base Clock ^" ) specially modified to be used by the invented Device (see Description of the Drawings and Figures: 1, 2, 3, 4, 5 and 6); which manage to measure the time of events of very long duration by means of a cam with tips, synchronized with the clock's wheel. Said tips by means of a rod give each step of one of them a movement in a ^" Step Drum Contometer ^" . These tips can also activate electrical contacts, or any system that manages to operate a contometer of any kind. That is why the same can also be achieved through a set of connected gears, with the proper transmission ratio, to a clock gear; activating in this case ^" Linear Drum Contometer ^" . Instead of days the Contometer can display hours or the desired unit of time; It only depends where the cam is placed and its number of tips or where the gears are placed and their transmission ratio.

THE ELECTRONIC CIRCUIT AND THE DESCRIPTION OF ITS OPERATION.- The Device when acting in accordance with the signals emitted in the external Telephone Central that belongs to the Telephone Company of the city, when the user calls and / or answers a call, connects or disconnects time measurement circuits, contometers and relays; that can activate or deactivate any internal and external equipment. As will be next and according to the circuit of Figure 7: DURING THE SLEEP THE PHONE.- The Relay (4) is in the ^" R ^" Standby position and due to the Diodes (3) and (14) no current passes through the

Device.

OFF - The Relay (4) is in the ^" R ^" position and the device receives the dial tone emitted in the Telephone System, which passes without causing any effect.

DIALED THE NUMBER TO CALL.- The Relay (4) is in the ^" R ^" position and the Device receives the signals of the dialed numbers, which pass without causing any effect. BUSY LINE.- The Relay (4) is in the ^" R ^" position and the Device receives the busy tone emitted in the telephone exchange that passes without causing any effect.

HANGING OCCUPIED LINE OR NO ONE ANSWERS CALL The Relay (4) is in the ^" R ^" position and the Device receives the busy tone emitted at the Telephone System, which passes without causing any effect.

WAITING FOR THE CALL TO BE ANSWERED: The Relay (4) is in the ^" R ^" position and the Device receives the signal that it is calling on the Telephone System, which passes without causing any effect. TALKING WHEN THE USER CALLED.- The Relay (4) is in the ^" R ^" position and the Device receives the signal emitted at the Telephone System, that the receiver of the call has picked up, which is directed by the Diodes (3 ) and (14) cannot pass through the Coil (5) because it does not have the energy necessary to overcome: the Resistance (1) and the Zener (2); whose added effects must not allow the maximum energy passing through the line in these conditions; therefore the energy, which in turn is controlled by the Resistance (12) and the Zener (13), only acts on the Call Clock (16); that omits counting the seconds that pass. If more contacts are needed, for a special application, you can place another Relay in parallel or build a Relay with more contacts. Additionally, it can be placed in parallel to the Clock (16): a Partial Call Clock (17) that has an option that allows it to return to zero and a Contometer (18) that adds up the number of times the user has been called.

The existence and value of the Capacitors (7), (8) and (15) depend on the brand and model of the Relay and the Clock

CALLING THE CALL.- The Call Clock (16) is working, the Relay (4) is in the ^" R ^" position and the Device receives the signal emitted in the Telephone System that the receiver of the call has hung up or the same caller has hung up; then the Rectifier Diodes (3) and (13) stop the Call Clock (16) and the Relay (4) is in the ^" R ^" standby position. If it is desired that the final Instance of the measurement of the use time of the telephone line is when the receiver of the call hangs up, then the Resistance value (1) must be increased to the maximum that allows the Coil to be activated. (5), when the phone rings

RINGING.- The Relay (4) is in the ^" R ^" position and the Device receives the ringing signal emitted at the Telephone System, which, being directed by the Diodes (3) and (14) overcomes the Resistance (1) and to the Zener (2), and places the Relay (4) in the ^" S ^" position by means of the Coil (5); So you can no longer pass the energy to the Call Clock (16) and close the circuit: Use of the Telephone Line when the User is Called, which activates the Clock (20). If more contacts are needed for a special application, you can place another Relay in parallel or build a Relay with more contacts. Additionally, it can be cast in parallel to the Clock (20): a Partial Answer Clock (21) that has an option that allows it to return to zero, and a Contometer (22) that adds up the number of times the user has been called. WHEN ANYONE ANSWERS.- The Relay (4) is in the ^" S ^" position and the Device receives the signal that originates when the person calling the user of the Device (who does not answer) hangs up. This signal emitted in the Telephone System causes the Relay (4) to go to the ^" R ^" resting position, due to: the Rectifying Diodes (3), (9), and the energy controlled by the Resistance (11) and the Zener (10) acting in the Coil (6).

ANSWERING.- The Relay (4) is in the ^" S ^" position and the Device receives the signal that the receiver of the call has picked up (in this case the user of the Device), which passes without causing any effect.

CUTTING THE ANSWER.- The Relay (4) is in the ^" S ^" position and the Device receives the signal emitted in the Telephone System, that the receiver of the call has hung up or the same person who has called hangs up. The Device by means of the signal that arrives when hanging any of the two people, makes change the Relay (4) to the rest position ^" R ^" and the Clock (20) stops; all this due to the Rectifying Diodes (3), (9), (14) and the energy controlled by the resistor (11) and the Zener (10) acting on the Coil (6).

THE CLOCKS

Figure 1 - INTERNAL VIEW OF THE "BASE CLOCK" WITH ALL ITS COMPONENTS. - All the systems of the "Analog Clock that serves as a base" and example, remain unchanged, and in the available space components have been added so that, with such changes, you can count the time of very long duration events such as the use of the telephone line in more than twenty years (thousands of days.) The aggregated components are marked ( ^* ). The total components are as follows:

A = Time Gear ( ^* ) B = Cam ( ^* )

5 in the outer circle of the graduation of the minutes and seconds, and in the upper left the window (W) built on its Support Box (O) where you can read the Contometer numbers for the days (E).

FIGURES 3 AND 4 - EXAMPLE - WITH CAM - This method of building the special Reloi, uses a Cam (B) that is synchronized (or glued) to the Time Gear (A). This Cam (B) produces, by means of the Vastago (C) and Ancora (D), that the Contometer Wheels (E) are moved. A gear Hours (A) of ^"24 ^hours" (Face of the ^"Clock ^Base" sample 24 hours instead of 12 hours), a cam is needed with a single tip. This tip produces a movement on the First Wheel of the Contometer (F) every 24 hours and shows the passage of one day. And so on. With a Gear of Hours (A) of ^" 12 hours ^" a five-pointed cam is needed, and the First Wheel of the Contometer (F) must be of another color.

The part of the Vastago (C) marked with x (X), has to be flexible so that it absorbs the small differences in the dimensions between the Vastago and the Cam; and the movement produces little resistance.

FIGURES 5 AND 6 - EXAMPLE - WITH GEARS.- This method of building the special Clock uses different gears: (J), (K), (L) and (M); with which the correct transmission ratio is found, so that the First Wheel of the Contometer (F) is moved once (or ten) each day. If it is preferred to move ten times each day, the First Wheel of the Contometer (F) must be of another color.
