Title: telephone fee meter
IPC: H04M15/28
Filed: 1972-08-23
Abstract: 1373727 Metering SODECO 23 Aug 1972 [1 Sept 1971] 39313/72 Heading H4K An arrangement for enabling and disabling a fee meter comprises a bridge arrangement made up of first and second temperature dependent elements and first and second resistors, which bridge arrangement is connected by a switching means to a counting relay of the fee meter, and the first temperature dependent element is thermally coupled to a device which is included in the subscriber line so as to be heated by the loop current. Resistors R 1 , R 2  and negative temperature coefficient (NTC) resistors NTC 1 , NTC 2  form a bridge circuit associated with which are transistors T 1 -T 3 , the transistor T 3  being connected to the counting relay A of the fee meter. When the subscribers line is not looped no current flows through heating element 3, which is thermally coupled to NTC resistor NTC 1 , and the arrangement is such that transistor T 1  is then on and transistors T 2 , T 3  are off. The fee meter A is therefore disconnected from the terminals 1, 2. When the subscribers line is looped the change in resistance of resistor NTC 1  causes transistor T 1  to turn off and transistors T 2 , T 3  to turn on. The fee meter relay is then connected across the terminals 1, 2 and can count metering pulses received for example by the audio-frequency fee pulse receiver of the installation. The arrangement is said to prevent the meter being operated during intervals between calls by spurious pulses. In order to prevent operation of the meter by ringing current nd to allow the final metering pulse following the termination of a call to be counted the NTC resistors have a thermal time constant. A zener diode D 3  is placed across the bridge arrangement to keep the potential across the two dividers constant.

Filed: 1974-09-16
Abstract: 1483903 Telegraphy SIEMENS AG 16 Sept 1974 [24 Sept 1973] 40207/74 Heading H4P [Also in Division G4] A data processing system includes a central unit comprising a central processor ZP, a store ASP, and an input output unit EAP, the last controlling data transfer between a number of peripherals PGE connected thereto and the central unit and comprising a control unit CCU connected to a chain of processors BL-MUX each of which includes a switching circuit and each of which is adapted, in response to control signals produced by the processor and by the control unit to connect the processor to data channels passing along the chain to the central unit and to prevent any processor further down the chain from responding to the control signals for so long as data exchange over the connected data channels continues. The I/O unit includes a chain of processors each of which may be a block multiplexer BL-MUX connected to associated peripherals via a control unit PST. The connections through the chain include input (relative to the central unit) channels ED, output channels AD, and a number of control lines. As shown in Fig. 3, the output channels AD may be connected via a switching gate S1 to data registers or buffers a. A switch S2 selectively connects either a source in the processor b or the channels ED from processors further along the chain to the channel ED to the central unit. The switches S1, S2 are controlled by unit VE in response to control signals and a comparison of coded signals from the central unit over lines AW1 and a coded signal derived by decoding COD a signal prewired into the processor by virtue of its position in the chain. The first processor in the chain receives a set of binary 1's over lines PNR, the lines passing to the next processor skewed by one bit with the unconnected line receiving binary 0. Thus each processor receives a code indicative of its position in the chain in such a way that processors may be added, up to a maximum number, or removed without requiring any change in their internal structure. The processor itself may select an operation by energizing via gate IG switch S2 and simultaneously energizing request control line ETA. Acknowledgement signals from the central unit are fed to the processors via line SPR and each processor, by gate 064 may block the line to further processors along the chain. It is stated that processors may be selected by lines AW2, one for each processor. Line ETA may also be used to request diagnostic &c. procedures in the central unit WF.

[Also in Group XL (c)] A circuit for controlling the striking phase of one or more gas-filled triodes 4, 5, comprises an auxiliary gas-filled triode 13 having a predetermined grid bias, a capacitor 15 charged with flat-topped half waves from a full wave rectifier 7 and a stabilizing tube 11 and an impedance 12 in the grid circuit of the tubes 4, 5 to be controlled and in the anode circuit of the auxiliary tube 13. The auxiliary tube 13 is held off by means of potential divider 19 until the biasing voltage is equalized by the voltage developed across the capacitor 15 which is supplied by the rectifier 7 in conjunction with the potential divider 9, 10 and the stabilizing tube 11. The auxiliary tube 13 then strikes and the capacitor 15 discharges through the rectifier 16 and the auxiliary tube 13 causing a voltage drop across the impedance 12. This voltage drop opposes the bias on the tubes 4 and 5 and one of them conducts depending on the phase of the supply cycle. Phase control up to and beyond 180 degrees is possible.

The Specification describes facsimile producing apparatus wherein a reproduction at 11 of an original 5 may be produced with any desired magnificatiori The original 5, in the form of a colour transparency, is wrapped around the outside of a transparent cone 1, rotated by motor 10. A light source 2 projects a beam of light through the transparency on to a scanning assembly comprising red, blue and green dichroic mirrors 8 and corresponding photomultipliers 9. Source 2 and the scanning assembly are moved together parallel to the surface of cone 1 and in a plane containing the axis of cone 1, by means of a lead screw 16 driven by motor 18 via gears 19. A point by point scan of transparency 5 thus results. The reproducing means comprises a light source 12, modulated by a signal derived by computer 14, from the outputs of photomultipliers 9, moving along a lead screw 17 turned by motor 18, parallel to the surface of a cone 15 rotating with cone 1. A layer of photo-sensitive material 11 is thus scanned by the light source, with the axial enlargement of the reproduction, with respect to the original, being dependent on their cones relative axial positions and with the circumferential enlargement made equal to said axial enlargement by corresponding differences in the scanning movement rates along lead screws 16 and 17 caused by gears 19. Since light 12 sweeps over material 11 at a speed which increases with distance from the cone base, the resultant decrease in reproduction intensity is overcome by variation of the average intensity of light 12 by means of potentiometer 20, geared to motor 18.
