Filed: 1963-12-02
Abstract: 984,206. Telegraphy. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 2, 1963 [Dec. 31, 1962], No. 47381/63. Heading H4P. In a data transmission system each N-th bit of one polarity is distinguishable from the previous bits of that polarity, the number N being adjustable. Mark and space bits appear on leads 23, 24 from input unit 22. The mark bits step down a counter 27 which is preset to an even number N set on store 40. When the counter gives an output pulse, the pulse passes via gate 43 and 30 to pulse stretching unit 31. A signal also delays the read out of the (N + 1)-th bit from unit 22; the N-th bit is stretched to occupy two bit lengths. The counter output pulse also causes the number stored in unit 40 to be reset in the counter. Space parity is derived in a similar manner. The number N may be varied during transmission. At the receiver the stretched pulses are detected, and if they do not occur at intervals of an even number of bits parity error is indicated.

Title: Time delay switches
IPC: H01H13/12
Filed: 1972-10-19
Abstract: 1389120 Retarding action of switches SIEMENS AG 19 Oct 1972 [10 Nov 1971] 48154/72 Heading HIN A time-delay switch comprises a plunger 1, displaceable by an operating element 3 to store energy in a store 11, and having an extension 12 which acts upon the free end of one of a set of contact springs 13, cam means 6 whereby the plunger 1, at a specific point in its movement, is disengaged from the operating element 3, whereupon further movement of the plunger 1 takes place independently of the operating element 3, under the influence of the stored energy, to produce timed-delay operation of said contact springs 13, one end only of said plunger 1 being able to move laterally. As shown, the element 3 comprises a hollow push button slotted at 4 to allow passage of extension 12. On depression of button 3 its skirt 9 engages a cam 7 to move plunger 1 until reaction of a cam 6 thereon with an abutment 8 pivots the plunger 1 about its lower end 2 so that cam 7 is freed from skirt 9 of button 3. The tip of extension 12 now lies beneath the end of contact spring 14 and as a spring 11 restores plunger 1 the contact 14 is lifted together with a diaphragm 16 to which it is attached by rod 15, air being drawn via a jet 19 from chamber 18 into chamber 17 and providing a pneumatic brake. At a predetermined point the extension 12 disengages from contact 14, plunger 1 snaps back to its rest position (shown) and contact 14 returns, under its own resilience and against the pneumatic brake, to its initial position. In a second embodiment (Fig. 2, not shown), the plunger extension 12 overlies the spring set, the upper contact spring forming the restoring force (in place of separate spring 11) while the lower contact spring is coupled to the diaphragm 16. In this case the chamber 17 is vented to atmosphere via an adjustable jet 19, and filter (22) and a valve (23) ensures that on depression of button 3 both contact springs are freely deflected (without alteration of their switching state) and on the automatic release of the plunger 1 from button 3 the upper contact spring restores while the lower spring is retarded by the pneumatic braking. Instead of providing time delay of contact closure the spring sets may be arranged to be closed for a precisely timed duration, i.e. delayed opening.

Abstract: 1,159,950. Preparation of chlorinated hydrocarbons. IMPERIAL CHEMICAL INDUSTRIES Ltd. 11 Sept., 1967 [31 Oct., 1966], No. 48703/66. Heading C2C. Hydrogen atoms in hydrocarbons are replaced with chlorine atoms by contacting a hydrocarbon selected from acyclic paraffins, olefins and benzene and its homologues with a mixture of molten metal chlorides comprising lithium chloride and palladium chloride. Other alkali metal chlorides and alkaline earth metal chlorides, for example NaCl, KCl, CaCl 2 , may also be included in the mixture. A particularly suitable melt system comprises by weight 20- 25% palladium chloride, 30-40% lithium chloride and the remainder potassium chloride. The temperature range for contact of the melt with the hydrocarbon is generally about 400- 850‹ C. The contact time may be from a few seconds to several minutes and contact can be achieved by any of the usual methods for reacting a gas with a liquid, for example a spray tower, a packed tower or a bubbling device. Hydrogen chloride is produced in the reaction and may be recovered by absorption in water. In a preferred method, HCl is absorbed in a spent-melt system where it regenerates palladium chloride from the metallic palladium formed during the chlorination of the hydrocarbon. The hydrogen chloride can be conveniently entrained in a carrier gas, for example nitrogen or air. The process as described for the chlorination of hydrocarbons can conveniently form the first stage of a two-stage cyclic process in the second stage of which a spent melt is partly rechlorinated with -hydrogen chloride from the first stage. Examples are given for the preparation of vinyl chloride from ethylene, of methyl chloride and methylene dichloride from methane, and of monochlorobenzene from benzene.

Abstract: 1505812 Address decoder TOKYO SHIBAURA ELECTRIC CO Ltd 2 Dec 1976 [5 Dec 1975] 50347/76 Heading G4H [Also in Division H3] A plurality of gates RD1-RD16 are used in an address decoder system, Fig. 1, each gate providing an output corresponding to a particular logical value of the inputs ABCD, whereby only one output can be logic 1 at any one time. Each gate has a configuration substantially as shown in Fig. 2 and will give a logic 1 output at R only when all the inputs A, B, C, D are logic 1 and the chip enable, CE, input is logic 1 (CE = 0) (positive logic convention). The circuit is said to give improved access time due to the rapid removal of store charge within the gate. The circuit comprises a NOR gate 62 (Q25- Q28) having one input CE and as the other input the output of OR gate 61 (Q19-Q24). The load device Q24 is shunted by Q23, whose gate is connected to CE. This ensures that, when the circuit is not selected (CE = 1) Q23 conducts and discharges any residual charge at node 60 to VSS, but when the circuit is selected (CE = 0) Q23 is OFF and has no effect. Q24 is always enabled as shown, but may have its gate connected to R1, when it will only be enabled when the chip is enabled and R1 = 1, Figs. 5, 7, not shown.  Operation.-With CE = 0, CE = 1, Q25 is OFF, Q27 ON and output R1 is 0, irrespective of the states of Q26, Q28. However as CE = 0, inputs A-D can have no effect, with CE = 1, CE = 0, Q25 is ON, Q27 OFF, and R1 will depend on Q26, Q28, i.e. the output of OR gate 61. If one or more of inputs A-D is logic 0, then one or more of Q19-Q22 will conduct, node 60 = 1, and Q26 is ON, Q28 OFF, and R1 remains 0. If all inputs A-D are logic 1, all of Q19-Q22 are OFF, node 60 = 0 and Q26 is ON, Q28 OFF, and R1 goes to logic 1.
