Title: Multiply Clocked Distributor Circuit.
IPC: H03K19/084
Filed: 1966-08-11
Abstract: 1,150,304. Data storage; printers. ANELEX CORP. 11 Aug., 1966 [11 Aug., 1965], No. 36069/66. Headings G4C and G4H. [Also in Division H3] In an electrical distributor circuit, timing means and delay means connected to their output produce two time-displaced pulse trains one of which drives a code generator driving a decoder and the other of which feeds gates pulsed in turn by respective outputs of the decoder. In Fig. 1, the state of a counter CG, advanced by clock pulses, is decoded by NAND gates at DG to earth four lines 2 in turn. In each case a corresponding NOR gate at ACG then at BCG is enabled by the clock pulses delayed at D1, D2, causing drive amplifiers at DAA, DAB to pulse a magnetic core matrix for read and write respectively, e.g. in a printer control system, such as that in Specification 1,056,906.

Title: Improvements in apparatus for the conversion of continuous or alternating electric currents into alternating currents of any desired frequency variable at will
IPC: H02M5/00
Filed: 1920-12-23
Abstract: 155,784. Soc. Anon. pour l'Exploitation des ProcÚdÚs M. Leblanc - Vickers, (formerly Soc. Anon. pour l'Exploitation des ProcÚdÚs Westinghouse-Leblanc). Dec. 23, 1919, [Convention date]. Low - pressure metallic - vapour apparatus; vacuum tubes.-A valve comprising one or more anodes, an incandescent cathode, and a grid interposed between the anodes and cathode, is filled with an inert gas or vapour, and is operated by insulating the grid or rendering it negative by opening or closing a switch. The valve may be used to change the frequency of an alternating current or to convert continuous current into single phase or polyphase alternating-currents of any desired frequency. Three-phase currents of ordinary frequency are converted into three-phase currents of high frequency by the arrangement shown in Fig. 9. The currents of ordinary frequency are first converted into high-tension continuous current by means of a step-up transformer 1, 2, 3 and a mercury-vapour rectifier 4, and the continuous current is then converted to threephase currents of the desired frequency. Instead of using four separate valves for this purpose, a single valve with four anodes B placed in extensions closed by the grids D is used. An incandescent filament may replace the incandescent mercury cathode, and the tubes may be filled with an inert gas such as argon or neon.

Abstract: 326,504. British United Shoe Machinery Co., Ltd., and Bates, A. Dec. 14, 1928. Splitting-machines.-In a machine for splitting the breast flap or otherwise operating upon the heel ends of soles, the sole is clamped upon a table 2, by fingers as described in Specification 302,944, reciprocated by a cam roll 9. The knife 4 is mounted on a bracket 14 pivoted on a pin 26 carried in eccentric bushes 34. A presser roll 3 is carried by the head of the bracket 14 and is adjustable relatively to the knife by wedge or screw mechanism. To lift the roll 3 as the sole is fed out of the machine the bracket 14 is tilted by a cam roll 33. To provide for variation in thickness of flap as the splitting proceeds the roll 3 is mounted eccentrically of the axis of its trunnions and is swung as described in Specification 302,944. The roll and the table may be shaped to cause transverse variation in flap thickness. The flap is caused to vary in two directions by the means described in Specification 281,787. The roll may be backed off as described in Specification 302,944. The table carries teeth 40, engaging driving-teeth on the roll 3, and is pivoted on a pin 41 and supported by rolls 42 from the shaft of roll 3. A presses roll 47 is held on a floating member 46 suspended from a shaft 143 and positioned by an adjustable member 50. Depression of a treadle actuates a rod 56 to lower the member 46 and to apply pressure through a plunger 51. A hand operated modification of the mechanism is shown. A sole stop 70 is suspended by levers pivoted to the casting and connected to the frame. On the initial downward movement of the member 46 the stop 70 is lowered into position but when the plunger 51 is depressed a link 76 is depressed to raise the stop.
