Filed: 1919-01-24
Abstract: 138,680. Miller, C. A., and Miller, F. J. Jan. 24, 1919. Burnishing by compression.-Sheet-metal circular stampings j are mounted on a rotating chuck c and are burnished by a spring-controlled tool g<1>, Fig. 4. The tool is adjustably supported on a slide e, Fig. 2, mounted on a lever d, which is pivoted on a bearing located under and in the same plane as the centre of rotation of the chuck c. A spring h holds a roller e<2> on the slide e in contact with a fixed cam i, Fig. 6, which surrounds the lever pivot and is selected to have an exactly similar contour to one half of the symmetrical article being burnished, so that, as the lever d is swung by means of a handle d<1> around its pivot, the point of the burnishing-tool g<1> follows the contour of the work. The pressure between the tool and the work is controlled by means of a spring g<2>, Fig. 4, and screw g<4>, and having once been adjusted remains constant during the swing of the lever. The slide e is retracted from contact both with the cam i and the work by means of a cam at the end of a side lever j', Fig. 6. A guard k and tray m are provided for flying particles of metal. A sliding rod mounted on a tailstock holds the article j firmly on the chuck c during the burnishing operation.

Abstract: 1456095 Cartridge feed for automatic firearms INDUSTRIE-WERKE KARLSRUHE AUGSBURG AG 14 Jan 1974 [27 Jan 1973] 01767/74 Heading F3C In an automatic firearm with a reciprocatory breech controlled by discharge gas pressure, a cartridge feed device 2 has two longitudinally parallel feed sections, each for receiving a cartridge belt 15 and is selectively transversely displaceable for cartridge feed from one of the belts such that one section is disengaged from a forward feed drive mechanism 8 before the other section is engaged, the drive mechanism having a gas discharge responsive piston to actuate the respective feed section for cartridge feed upon breech recoil. Recoil gas acts on a lateral piston having a rack formation to rotate directly one pinion 8f and a second pinion 8c via the first pinion, the pinion being connectible to parallel longitudinal shafts 2b dependent on lateral positioning of the feed device 2, which contains spiders 4 accepting the respective belts 15 of different ammunition. When one form of ammunition is to be used, the shaft 2b of the corresponding spider 4 has a T-end which engages a corresponding part of the pinion 8e, 8f for spider rotation; as can be seen in Fig. 5, the ammunition acceptance position is at an angle to the vertical. A further clip of ammunition 17 of different type may be inserted for feeding. Lateral feed device movement is facilitated by a lateral bar 2a of the device 2 slidable in a sleeve fixed to the device 8. Thus three types of ammunition, e.g. armour piercing, explosive, tracer, and target marking ammunition can be fired at will.

Filed: 1918-02-04
Abstract: 119,791. Armstrong, J. E. Feb. 4, 1918. Cylinders, draining and relieving.- An automatic drainvalve for engine cylinders and turbine casings is constructed so that the engine may make a number of revolutions for one opening of the valve to permit the escape of the condensationwater. In the construction shown in Fig. 1, the valve is secured at p to the engine cylinder or turbine casing, and at o to the valve-chest or steam supply. The valve is provided with a head h secured to the rod f of a piston e. The valve cylinder is provide with ports m communicating with the chamber c which is provided with an outlet j, and with miniature ports n in the gland g. When the valve is forced off its seat by excessive pressure, the condensation-water enters the cylinder through ports m, n. When the pressure falls, the pressure on piston e first closes the ports m, and then the piston rises slowly, forcing the water in the cylinder a<1> through the ports n. In a modification, the valve is provided with two seats and connexions for the two ends of the cylinder or casing. In a further modification the valve is provided with a passage controlled by a ball valve in lieu of the ports m.

Title: Matrix translator with a capacitive coupling between the row and column wires
IPC: G06V30/194
Filed: 1962-01-19
Abstract: 948,179. Electric learning circuits. STANDARD TELEPHONES & CABLES Ltd. Jan. 19, 1962 [Jan. 20,1961], No. 2034/62. Heading G4R. In a learning matrix the column and row conductors are coupled by equal capacitors at each cross-point and certain ones of these capacitors are reduced in value during the learning process by burning out under the influence of coincident voltage applied to column and row conductors. The conductors are thin strips as shown in Fig. 1 deposited by evaporation on a base. The dielectric, which is preferably some inorganic material such as a silicon or metal oxide, is also deposited by evaporation. When overloaded the dielectric breaks down and a small part of the metallic coating burns away in that area so that although the capacitor is not permanently shorted, the the effective capacitance is reduced. To avoid the possibility of a conductor burning right across as at a on successive applications of breakdown voltage, the conductors or the dielectric may be specially thickened in one place. Alternatively the conductors may be separate from the capacitor coating KX and KY, Fig. 2, the conductors being relatively small. The dielectric is strengthened at D1 to prevent breakdown at the cross-points. For each column of the matrix there may be two conductors X1, #X1; X2, #X2 &c. Fig. 3 receiving the true and complement signals of the input pattern. The two sets of conductors may be on the opposite sides of the set of row conductors two intervening dielectric layers being provided. A.C. or pulses of D.C. may be used for the burning out process. The arrangement of Fig. 3 has switches T1, T2 &c. in the primaries of transformers the secondaries being centre tapped to apply to the true and complement conductors voltages of the same amplitude but of opposite phase. The outputs from the row conductors during a translation operation are applied to phase or amplitude sensitive units,to determine which of the learned patterns most closely matches the input pattern. Specification 939,134 is referred to.

Abstract: 895,775. Automatic circuit - breakers. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Jan. 19, 1959 [Jan. 23, 1958], No. 2336/58. Class 38 (5). A circuit-breaker has an overload-responsive bimetallic member 20 associated with a pivoted lever 27, an overload-responsive electromagnet 13 with a pivoted armature 34, and an earth-leakage responsive electromagnet 23 with an armature 30 having a projection 55 normally latching a cam-like member 40 connected by a link 42 to the joint 46 between links 43, 44b extending between an actuating dolly 47 and a lever 44. To close the circuitbreaker, the dolly 47 is turned anticlockwise from the position shown in Fig. 6 so that the links 43, 44b turn the lever 44 to cause arms 44a of the lever to push down composite spring members 5 and close main contacts indicated at 3, 12 and to close arcing contacts 9, 10, overcentre tension springs 52 maintaining the dolly 47 in its " on " position. In the event of earthleakage, the armature 30 is attracted by the electromagnet 23 to release the member 40, which turns clockwise due to the thrust exerted by the spring members 5 and permits the linkage to collapse so that the contacts open. Similarly in the event of light sustained overload the bimetallic member 20 acting through the lever 27, or in the event of heavy overload, the armature 34, pushes the armature 30 against the bias of a compressionspring 33 to release the member 40. Since, on light overloads the bimetallic member 20 causes the movement of the armature 30 against which the armature 34 bears, the overload current necessary to produce tripping by the overload electromagnet 13 is less if it follows a period of light overloading than if it does not.
