Title: Improvements in code communication systems
IPC: B61L7/08
Filed: 1955-08-16
Abstract: 797,140. Patternmovement stepping registers. GENERAL RAILWAY SIGNAL CO. Aug. 16, 1955 [Aug. 17, 1954], No. 23615/55. Class 106 (1). [Also in Group XXXVIII] In an electronic pulse code communication system, e.g. for the control of track switches, signal devices &c. at one or more remote field stations along a section of railway from a control office, and the transmission of indications to the control office (see Group XXXVIII), each field station is provided with a shift register 19 which prior to the reception of a control code is selectively conditioned in accordance with an indication code to be transmitted to the control office, and when the received control code is stepped into the first stage of the shift register the stored indication code is stepped out of the last stage. Each stage of the shift register comprises two grid-controlled cold cathode tubes, a storage tube 360 providing for the storage of a code digit, and an intermediate tube 361 providing a temporary storage for a digit as it is transferred from one stage to the next. The cathode of each storage tube is connected to wire 115 and the cathode of each intermediate tube to wire 116, the wires 115 and 116 being supplied with square-wave shift pulses of opposite phase. Each storage tube, other than that in stage 0, receives an input from the plate of the intermediate tube in the preceding stage and each intermediate tube receives an input from the storage tube in the same stage. Prior to the reception of a control code, positive-going code impulses indicating the condition of controlled apparatus are applied in parallel mode to the grids of the storage tubes of the appropriate stages Nos. 1 to 15 to. cause these tubes to fire. The shift pulses on wires 115 and 116 then step the indication code from stage to stage, the final stage No. 15 having its tubes made selectively non-conductive and conductive on successive pulse periods in a time-spaced pattern and an output being taken from this stage to modulate a carrier transmitter to transmit the indication code to the control office. As the indication code is stepped out of the shift register a control code in serial mode is applied over wire 397 to the grid of tube 360 in stage No. 0 of the shift register and is transferred from stage to stage by the shift pulses until the storage tubes of stages Nos. 1 to 15 are conductive or non-conductive in a pattern representing the control code. The occurrence of the shift pulses is synchronized with the received control code digits in such a way that wire 115 is always at a low potential as each code digit is applied to the grid of tube 360. The control code stored in the register is then utilized to selectively operate relays 20A or 20B in response to the operation of relay 121 or 131 by a further timing pulse. To cancel all signals stored in the shift register in readiness for the next cycle of operations the voltages on wires 115 and 116 are caused to be in phase.

Title: Improvement in phonographs
IPC: H04R11/08
Filed: 1936-08-28
Abstract: 464,739. Phonographs. DICTAPHONE CORPORATION. Aug. 28, 1936, No. 23631. Convention date, Oct. 4, 1935. [Class 40 (ii)] Relates to phonographs of the transcribing kind in which the reproducing unit is mounted to have up and down movement to permit its disengagement from the record and a certain amount of lateral play while tracking the record. According to the invention, a single device is provided which in normal position permits free operation of the reproducer on the record, and can be moved to two other positions, in one of which lateral play is prevented and the reproducer centred for back spacing, and in the other one of which the reproducer is not only centred but is lifted off the record. In the form shown, the reproducer, which is described in Specification 6581/37, is mounted in a housing 18, Fig. 1, pivoted on horizontal pivots 30 on a vertical shaft 28 supported by pivots 27 in a bracket 26 on a plate 33 attached to a usual carriage 10 guided on rods 9, 11. The weight of the reproducer is partly balanced by a mass 32 secured by a screw 33 in the front part 20 of the housing which is stepped below the rear part 18 to enable the pivots 30 to be placed approximately on the tangent to the record cylinder 14 at the point of contact of the stylus 21. A tongue 43 depends from the housing 18 and the upper end 63 of a lever 60 projects through a slot 44, Fig. 6, in this tongue. Behind the tongue, the lever is formed with lateral cams 67 and a vertical cam 64. The lever is pivoted at 61 on the carriage and its lower end co-operates with a cam 58 on the usual " conditioning " lever 57 and with'a cam 66 on the usual half-nut 54, which co-operates with the usual feed screw 55. When the usual backspacing lever (not shown) is depressed, it rocks the half-nut 54 away from the screw 55 in the usual way, and the cam 66 thereon rocks the lever 60 sufficiently to make the lateral cams 67 enter and fill the slot 44 of the tongue 43, thereby centring the reproducer. When the " conditioning " lever 57 is lifted, the nut 54 is also disengaged from the feed screw, but the cam 58 deflects the lever 60 to a greater extent and the reproducer is not merely centred by the cams 67 but the cam 64 also enters the slot 44 and lifts the reproducer off the record.
Patent GB-236517-A (GB)
Abstract: 236,517. Dennison, W. N. July 2, 1924, [Convention date]. Tool-arms and mountings. - The reproducing-tool holder is mounted on trunnions 86, Fig. 12, each of which has a tapered portion 87 engaging bearing members 88, 90. These are mounted in a block 92 held in a support 93 on the casing. A special construction and mounting of the diaphragm 18 are described, and it is stated that with these devices it is not necessary that the movements of displacement of the diaphragm should be as great as in a sound-box of usual construction. Accordingly, the pivot of the stylus-bar 85 is nearer to the link 95 which coinnects the bar to the diaphragm than to the point of the stylus 84.

The tube may be roughened and it may have a coating to facilitate adhesion of the oxide coating. The tube and the wire may be of nickel, copper, iron, tungsten tantalum, niobium, molybdenum or alloys thereof. The tube acts as the conductor for the heating circuit.

The working jet of a high vacuum condensation pump issues from an annular nozzle 8 which is supplied with vapour e.g., carbon dioxide or dichlorodifluoromethane through a valved duct 5 from a storage vessel 14 at normal temperature and about 4 atmospheres pressure, and condensation of the jet is effected against the pump wall which is surrounded by liquid nitrogen in a Devon flask 3 open to the atmosphere. The vessel 18 to be evacuated is connected to the upper end of the pump body 2 and the pump exhausts through a tube 7 to a backing pump. In a modification the condensed vapour is collected in a flask detachable from the pump body and serves as a replacement for vessel 14.
