Title: Improvements in or relating to electronic shift registers
Inventor: JONES ERIC LINDSAY
IPC: G11C19/28
Filed: 1963-01-11
Abstract: 986,868. Shift registers. STANDARD TELEPHONES & CABLES Ltd. Jan. 10, 1964 [Jan. 11, 1963], No. 1373/63. Heading G4C. A plurality of stages of an electrical binary shift register each comprises a master MX1a, MX1b and a slave SX1a SXlb bi-stable device in which the shift pulses are not applied to the master bi-stable devices. A shift pulse applied to the last slave bi-stable device causes the slave devices each to assume the inverse of the previous master device which are "unlocked" and assume a neutral condition. When the shift pulse ends the slave devices resume their neutral conditions and the master devices each take the inverse of the previous slave. The register may be split into a number of sub-registers with the shift pulse applied to the final slave in each sub-register and each coupled by a pair of NOR elements Ca, Cb with inputs transposed. Since the coupler Ca, Cb does not have to gate the previous device the dotted connections may be omitted. Each sub-register may comprise a single stage in which case the cross-couplings between the master devices MX1a MX1b may be omitted together with those between the master MXla, MXlb and the previous coupling Ca, Cb. The bi-stable devices are each formed from a pair of transistor-resistor-logic NOR or NAND elements.

Title: Improvements in or relating to Hand Grenades, Bombs and the like.
Inventor: HARRIS HENRY KINGSFORD
IPC: F42C1/06
Filed: 1916-02-03
Abstract: 105,932. Harris, H. K. Feb. 3, 1916. Projectiles; projectile fuses.-Relates to bombs and grenades fired by a spring-striker which is released on impact by a movable weight. According to the invention, the weight is made on opposite sides with curved or inclined surfaces and is disposed between similar surfaces on a pair of members, which, on impact, are moved by the weight to cause the release of the spring-striker. In the form shown in Fig. 1, the spring-striker 3 is contained in a tube 2 and is held cocked by an external lever 4, which is itself held by a trigger 10 under the influence of a spring 19. The movable weight, in this case a ball 22, is situated between concave faces on movable plugs 16, 23, which are connected to the trigger 10, so that the movement of either plug or of both, when the weight is displaced on impact, causes the trigger to be deflected about its pivot 9 thereby releasing the external lever 4. This fuse is locked at safe until discharge by a pin 15<1>. In a modification, the ball is loosely mounted between cups carried by a pair of interconnected levers adapted to release a lever which is situated within the same chamber as the ball and normally holds the spring-striker cocked; in this case, the striker acts in a direction opposite to that shown in Fig. 1, and is hollow for the accommodation of the detonator and perforated to enable the detonator to burst the tube containing the striker. The pair of levers is held at safe by a spring plunger, which is released bv an external strip when the grenade is thrown; the external strip is normally locked by a pivotal latch, which is itself locked by a pin. Provisional Specification 1627/16 also describes the use of (1) spring-controlled weights and pendulums, (2) two sets of movable weights acting in succession, (3) the explosive charge as movable weight, (4) the direct action of the movable weight on the detonator, (5) electric and chemical fuses, (6) the grenade handle as the movable weight, (7) the shock of throwing to cause the movement of the weight, (8) springs for preventing the movement of the weight on light accidental impacts, (9) removable pins for varying the sensitiveness to impact, and (10) a timing device to release the action before impact. Provisional Specification 2129/16 also describes (1) the. use of the impact action to cut off a time fuse if the grenade is accidentally dropped after the time fuse is started, (2) a handle connected to the grenade by a universal joint, (3) a flexible handle, and (4) safety catches for the handles.

Title: Improvements in and relating to axial-flow compressors having bleed valves
IPC: F04D27/02
Filed: 1957-01-16
Abstract: 808,094. Axial flow compressors. GENERAL MOTORS CORPORATION. Jan. 16, 1957 [Jan. 18, 1956], No. 1631/57. Class 110 (1). [Also in Group XXIX] An axial flow compressor for a gas turbine engine has at one or more compression stages an annular row of air bleed-off apertures 30 covered by a manifold associated with a number of bleed valves under the control of a solenoidoperated valve supplied from a high-pressure stage. Each manifold has three arcuate sections 32, 34 and 36 and is provided with four bleed-off valves 38, each comprising a piston 62 with a portion 64 to co-operate with a seat 58 surrounding a discharge port 66. The piston 62 operates in a cylinder 54 having an inturned flange 70 and is slidably engaged by a pistonring 76 mounted for limited axial movement relative to the piston in a recess 72. The actuating pressure supplied by a passage 68 causes the piston-ring 76 to seal positively against the flange 70. Leakage along the inner periphery of the ring is prevented by a flexible packing-ring 84 in a groove 74. The cylinder 54 is mounted between a head 52 and a three-legged cylinder ring 56 held in place by screws 60. The valves 38 are controlled simultaneously by a three-way solenoid valve 42 which disconnects the cylinders 54 from a high pressure stage of the compressor and connects them to atmosphere through a conduit 44 when the solenoid is energized. This takes place when a switch 51 is closed by a speed-responsive device at low engine speeds.

Title: An improved manufacture of petrolatum and petrolatum oils
IPC: C10G73/36
Filed: 1925-08-25
Abstract: 259,442. Lavirotte, F. Aug. 25, 1925. Addition to 240,803. Mineral oils, purifying. - Highly purified petrolatum and petrolatum oils are obtained by heating the crude materials with strong sulphuric acid until the impurities are converted into undissolved solid or semi-solid carbonaceous matter, separating the liquid, and extracting the residual petrolatum from the carbonaceous matter by a solvent. Preferably fuming acid is used, and the matter treated is distributed in an inert menstruum, e.g. the product of the process. Crude materials specified are crude petrolatum, petroleum grease, black oils, dark machinery oil, mixtures thereof, and low grade residues of petroleum distillation. In an example, 1 ton of crude petrolatum is agitated below 100‹ C., e.g. at 60- 70‹ C. for about 24 hrs. with 1.5 tons of 20 per cent oleum, and then for about 48 hrs. at below 200' C., e.g. 160-170‹ C. The mass is allowed to cool to about 100' C., the liquid withdrawn, and the more or less solid residue extracted with benzol or naphtha. The petrolatum dissolved is recovered by distilling off the solvent. or by chilling the solution; it is added to that separated as liquid. The total petrolatum is freed from dissolved sulphonated compounds by treatment with 30-40 per cent of 20 per cent oleum at about 150-160‹ C. for about 36 hrs. and separation of the carbonaceous mass as before, or by dissolving out the petrolatum with a solvent such as light naphtha or benzol in which the sulphonated bodies are insoluble. The product may be neutralized by agitation with 10 per cent by weight of filter clay and 1.5 per cent of calcium carbonate for 3-4 hrs. at about 120‹ C., and then filtered through clay. The clay may be fitted for reuse by extracting retained petrolatum by naphtha, and then revivifying in known manner. The residual carbonaceous matter is heated to about 400‹ C. to remove volatile matter, ground e.g. in a ball mill, and then agitated at a red heat in contact with air until about half consumed; a highly adsorptive carbon results. Sulphur dioxide evolved during any of the above processes is absorbed in an alkali, e.g. a 28 per cent solution of sodium carbonate, to produce bisulphite.
