Abstract: 1,125,375. Automatic exchange equipment. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 29 Dec., 1966 [24 Jan., 1966], No. 3133/66. Heading H4K. A register for use in a telephone system comprises reed relays, such as XYWZ, which lock up or stay back according to whether a binary mark is or is not present on an input, such as lead d associated with relay Z; those energised relays of a register priming associated gates, such as GIC for relay Z, over which gates the registered word may be read out non- destructively. To seize a register group a lead B is marked to operate relay H and connect common lead OHL to earth over rectifier HD. To write a word into the register, marks are applied to the appropriate leads d, transistors such as TR4 conducting to connect earth to the corresponding relays which lock up to 24 volts negative over a resistor r on one side and to 24 volts positive on OHL derived from transistor TR2 switched on by TR1 which conducts in response to a write priming signal on lead A. To read out, the lead A is again primed to put 24 volts positive on the rail OHL, rectifiers MRO associated with operated relays being back biassed by the 24 volts negative over resistor r but those rectifiers MRO associated with unoperated relays transmitting the voltage to the associated gates GIC. When the gates GIC are interrogated by pulses on terminals p output appears on terminals OP only in respect of those gates conditioned by operated relays. To clear the register a signal on lead B causes TR5 to conduct so that a signal on lead C can cause TR3 to conduct. With both sides of the relays at earth locked up relays release. A second register with relays S and T is shown. Resistors RO simulate further relays in this register, simulated lock-up contacts CRO being operated when these binary bits are required to be read out.

Title: Improvements in or relating to oxy-acetylene welding or cutting equipment
IPC: F23D14/46
Filed: 1943-03-04
Abstract: 564,318. Oxyacetylene burners. TALLEY, H. A. E. March 4,1943, Nos. 3545 and 16427. [Class 75 (i)] [Also in Group XXIX] In an oxyacetylene welding or cutting apparatus the passage of one of the gases to the burner nozzle reduces the pressure on one side of the diaphragm of a " sensitive demand regulator " to less than atmospheric pressure and the diaphragm is operated by the atmospheric pressure on its other side to open a valve to allow the passage of the other gas to the burner nozzle. In the apparatus shown in Fig. 1 the passage of the oxygen from the cylinder A through a ventilator tube C to the burner nozzle D produces at the oxygen jet C<*> a subatmospheric pressure which is communicated through the oxygen supply pipe to the left side of the diaphragm 14 of the sensitive demand regulator F. The diaphragm 14 consequently moves to the left and operates levers 22 to move a headed pin 21 against the resistance of a spring 23 to allow a valve 19 to lift from a small valve opening 18 and oxygen to pass to the burner nozzle. The oxygen and acetylene supply pipes may be fitted with fine adjustment control devices B consisting of inner and outer stepped bodies 5, 6, the inner body having a gas passage 7 controlled by a pin 9 on a plate 8 guided by a steady pin 10 and adjusted against the resistance of springs by a nut 12 on a spindle 11.

Abstract: 658,671. Monitoring radio apparatus. RADIO CORPORATION OF AMERICA. Feb. 11, 1949, No. 3830. Convention date, Feb. 12, 1948. [Class 40 (v)] A monitoring system for a plurality of signal channels comprises a superheterodyne receiver with means for amplitude-modulating the locally-produced oscillations with a waveform having a fundamental frequency equal to that of the separation between the channels. In the Figure, oscillations from radio frequency amplifier 10 are heterodyned in mixer 12 with oscillations from oscillator 14, and then applied to the normal I.F. amplifier, detector, audio amplifier and output stages 17, 18, 20, 22. The oscillations from oscillator 14 are amplitudemodulated by means of a stable oscillator 16, so that for a sine wave modulation frequency, the output from oscillator 14 comprises the basic frequency and two side bands. Consequently, supposing the frequency of oscillator 16 to be 10 kc/s., three incoming signals to aerial 24, say of frequencies 2330, 2340, 2350 kc/s., which are separated by a frequency equal to the fundamental frequency of oscillator 16, may be selected by the intermediate frequency amplifier and applied to the loudspeaker 22 for monitoring purposes. The waveform from oscillator 16 may be complex, the presence of harmonics enabling a larger number of signal channels to be received, and the fundamental frequency may be greater or less than the bandwidth of the intermediate frequency amplifier. A switch 15 is provided, so that oscillator 16 may be disconnected, the arrangement then being used as a conventional receiver.

Abstract: 1449954 Automatic control of speed ARVIN INDUSTRIES Inc 28 Jan 1974 [29 Jan 1973] 03923/74 Heading G3R In a video recorder with a motor driving a recording medium e.g. a disc, a phase locked motor speed control uses a desired speed signal that is derived by a horizontal synchronized signal separator and a divider from an input video signal. The divider has a variable, but integral, ratio so that the desired signal has a constant frequency despite different horizontal synchronized frequencies. In the embodiment, for the recording mode, vertical and horizontal synchronized signals are separated at 20. The vertical signals are used to open gate 13 to allow input video signals to pass to a recording transducer 15. One input frame is recorded on disc 16 for each revolution of the disc, then the transducer 15 is moved to a different position. The horizontal synchronized signals pass via variable ratio divider 35 to detector 30, where the phase of the divider output is compared with signals from motor driven tachometer 25, having a frequency proportional to motor speed. The result of the comparison is used to vary the drive to D.C. motor 18. On play back the horizontal synchronized signal is replaced by an output from oscillator 37. The divider circuit, also Fig. 2 (not shown), comprises a monostable multi-vibrator which automatically divides the input horizontal synchronized pulses by an appropriate integer so as to maintain its output frequency constant.
