Title: Automatic dialler
IPC: H04M1/278
Filed: 1966-12-22
Abstract: 1,135,960. Pulse transmitters. INTERNATIONAL STANDARD ELECTRIC CORP. 22 Dec., 1966 [30 Dec., 1965], No. 57380/66. Heading H4K. In a device for generating dialling pulses, a counter is preset in successive cycles to counts corresponding to successive digits read from a record and is stepped to a predetermined count during the remainder of each cycle to control the generation of dialling pulses. The device may be a punched card controlled repertory dialler or as described controls connection of remote printing telegraphs through a telephone exchange. The telephone number of a remote telegraph is punched as a header block on the message tape of a local telegraph. Successive characters read from the tape are applied to a code converter which gives an output corresponding to the tens complement in four bit binary of each digit read from tape. The characters read from tape are also applied to a code detection circuit which responds to the detection of figure shift and letter shift characters. On detection of a figure shift character a request to dial signal is sent to line and on receipt of a proceed-to-dial signal flip-flops 13, 14 are set to enable an AND gate 17 to pass stepping pulses from a distributer 4 to the stepping magnet for the tape. For each step of the tape the tens complement of the digit read passes through a gate 26 and sets a binary counter 25 to this value. Dialling pulses are generated by a recirculating pattern moving stepping register 21 comprising a three stage shift register with the output from the last stage fed back in inverted from as an input to the first stage. The register is stepped at a 20 millisecond rate by a pulse generator 23 and cycles through five different combinations before being reset through an inverter 28. An output from the second stage comprising mark signals of forty millisecond duration alterated by space signals of sixty millisecond duration conform to the required dialling pulse format. This output is applied as a stepping input to the counter 25 and to a gate 29. A flip-flop set at the count of 16 (i.e. at the point at which the counter starts to recycle and at which it is set to the tens complement of the digit to be transmitted) and reset at the count of ten. While set, the flip-flop enables the gate 29 to pass the correct number of dialling pulses to line. It then resets for a period of six counts thus closing the gate 29 for a period of 600 milliseconds to give the correct inter-digit spacing. The tape may have the called number repeated in several successive blocks on the tape to enable a repeat attempt if connection is not made on the first try. Receipt of a signal unique to an established connection inhibits further operation of the pulse sender and causes rapid stepping of the tape until the letters shift character is detected.

Title: Device for measuring the rate of flow of a medium
IPC: F15C1/08
Filed: 1971-12-17
Abstract: 1372734 Fluid regulation P S BAHRTON 17 Dec 1971 [22 Dec 1970] 58734/71 Heading G3H [Also in Division G1] A bi-stable fluidic device, which when associated with a recording unit 8 can be used for measuring the flow rate of a medium passing through the device, comprises an inlet passage 1, two outlet passages 5, 6 and two control chambers 2, 3, the control chambers being inter-connected by tubing 7. With fluid flowing through outlet 6, a vacuum is created in control chamber 3, such vacuum causing fluid to pass from the other chamber 2, through the tubing 7 and hence into chamber 3. Accordingly, the flow is caused to switch over to the outlet 5. Thus, the inlet flow oscillates between the two outlets 5 and 6. Such oscillation is represented in the tubing 7 which has a tapping 7a leading to the recording unit 8. The recording unit may alternatively be connected to one of the outlet passages. The oscillating signal received in unit 8 is representative of the flow rate of medium undergoing oscillations between the two outlet passages. Thus, such signal can be utilized as a measure of the flow rate.

In a safety system comprising an alarm 17 operated by a relay 16, a generator 2 is associated with a modulator 4 for controlling a motor 6 by square wave pulses having a constant "on" time and variable "off" time. During the "on" time of the pulses from modulator 4, diode 12 conducts to charge capacitor 18. During the "off" time of the pulses, capacitor 18 discharges to charge capacitor 14 and to energize the relay 16. Diode 20 isolates capacitor 14 and relay 16 whereby the only discharge path for the capacitor is through the relay. A safe condition is indicated when the relay is energized, a failure being indicated by de-energization of the relay. A steady output rather than a pulse output from the modulator operates the alarm; which is also operated when there is no output from the modulator. The system detects an open or short-circuit failure of the components in monitor 5. The pulse generator 2 is connected to a D.C. source and it is manually operated, or controlled by a logic circuit 8.

Abstract: 632,196. Electric totalizators. UNION TOTALISATOR CO., Ltd., and HANDLEY, J. March 10, 1947, No. 982. [Class 40 (i)] A totalizator system has an additional aggregator which adds the totals on the runner aggregators, after the close of betting, for comparison with the grand total aggregator. As shown, each runner aggregator comprises units, tens and hundreds registers UA, TA, HA and at the close of betting a momentary operation of key K starts a distributer UD which connects up the units registers of all the aggregators in turn and transfers their settings to relays 1 ... 0. Other distributers (not shown) similarly transfer the settings of the tens and hundreds registers. Each relay 1 ... 0 energizes an appropriate combination of escapement magnets 1U...4U which in the manner described in Specification 569,879 allow the units register of the additional aggregator (not shown) to rotate by a corresponding amount. Transfer between the registers of the aggregator is as described in the above Specification and in Specification 592,946. Assuming correct response of the escapement magnets, a circuit is made for relay R which reoperates the driving magnet DR of the distributer to release the relay 1 ... 0. Relay R is thus released and the distributer moves on to connect up the next aggregator.

Abstract: 764,126. Cash registers. NATIONAL CASH REGISTER CO. Jan. 13, 1955 [Feb. 25, 1954], No. 1048/55. Class 106 (1). Differential mechanism. In mechanism comprising a setting member, e.g. the minimum movement beam 395, Fig. 1, differentially adjusted under the control of depressible keys and adapted to be driven from a differentially set position against a fixed stop (collar 234) by a driving member (cam follower lever 405), the driving member is overthrown beyond the driving position and impacts the setting member through the intermediary of a resilient member. The mechanism shown is associated with the transaction differential of a cash register or similar accounting machine, and the invention ensures the beam 395 and mechanisms controlled thereby are accurately set according to a selected function, e.g. totaltaking. The follower lever 405 is adapted to rock a driver plate 396 for a latch plate 397 to which one end of the beam 395 is connected, a depressed key tripping and locking the latch 398 of plate 397 after it and the forward end of the beam have been positioned according to the depressed key. Thereafter a roller 411 on the follower lever 405 bears against the beam and forces it against a collar 234 on the pivot shaft 233, the differential movement so imparted to the beam being transmitted through linkage 391-394 to a control shaft 387. According to the invention the roller 411 is constructed with a resilient core 12 of rubber, Fig. 3, which is fused to the roller and an inner sleeve 13 journalled on a stud 14 secured to the lever 405, the core 12 being compressed during operation of the mechanism so as to press the beam 395 firmly against the collar 234 despite wear and looseness in the driving parts.
