Title: Improvements in or relating to electrical pellet primers
IPC: F42B3/12
Filed: 1954-07-19
Abstract: 752,724. Electric igniters. MENKE, J. F.; and DOERPINGAUS, E. H. July 19, 1954 [July 17, 1953], No. 20980/54. Classes 9(1) and 9(2) An electric igniter for blasting cartridges, projectile fuzes, propellants and flash powders comprises leg wires 2, 3 passed through a glass bead 1 coated with an electrically conductive metal such as platinum. The thickness of the coating may be sufficient to produce a resistance of 40 to 100 ohms between the two wires. Over this coating is a layer of a priming composition, such as cuprous carbide, covered by a layer of thermally insulating material, such as nitrocellulose, separating the primer from a surrounding detonating charge 5, which may be lead azide. The charge 5 is in a casing 6 closed at one end by a destructible membrane 7 and at the other end by a plate 8, the closures being secured by beadings 9, 10. Extending through the plate 8 is a contact 11 mounted in an insulating sleeve 12 and housing the outer end of leg wire 2. The second leg wire 3 extends along a groove in the periphery of the plate 8. In a modification, Fig. 2, the wires 2, 3 project at both ends from the bead 1, the shorter wire 3 being engaged in grooves in a contact member 13 surrounded by an insulator 14, which fits within a metal sleeve 15. Grooves in the sleeve 15 receive the ends of the leg wire 2 and are clamped by a, cap 16 which holds the charge 5, part of which extends into the contact member 13. A flash passage 19 in the cap 16 communicates with a chamber 20 of the ignition device. The wires 2, 3 may be a nickel-chrome alloy. To produce the igniters, two parallel wires are passed through a, machine in which glass beads are fused at regular intervals to the wires and the resultant chain is passed through a metal salt solution. The coating is heated to reduce the salt to metal and the process repeated until the required thickness of metal is deposited on the beads. The bead chain is then calcined to bond the metal to the glass. The layer of priming composition may be deposited on the bead from a solution or applied by pressing. On completion of the coatings the wires are cut between the beads. For the detonator of Fig. 1 the wires may be inserted in the plate 8 prior to cutting. When making the fuze shown in Fig. 2, the wire 3 is cut intermediate the beads and the beads are connected to the contacts 13, 15 prior to cutting the wire 2. The beads may be made of ceramic materials. Specification 652,802 is referred to.

Title: Improvements in electronic digital computing machines
Inventor: WILLIAMS FREDERIC CALLAND
IPC: G11C11/23
Filed: 1949-08-17
Abstract: 734,483. Digital electric calculating-apparatus. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Aug. 2, 1950 [Aug. 17, 1949], No. 21443/49. Drawings to Specification. Class 106 (1). An electronic digital computing machine of the series-mode pulse train type employing electrostatic digital storage devices, is arranged to operate with a beat interval which accommodates a number of digits a which is a submultiple of the number of digits b in the basic length number. word utilized in the machine, and the transference of such basic length number  words, when they occur, is effected during b/a successive beats under the control of a single instruction. The invention is applicable to machines, such as those described in Specifications 705,479 and 731,341, with an operating cycle of " four beats to a bar," and is intended to achieve increased speed of operation. Since instruction 'words do not normally exceed 20 digits in length, and number words also are often within this limit, the machine described is designed around a 20-digit number and is provided with means, operative when number words of more than 20 digits occur, to modify the operating cycle by addition of an extra action beat to accommodate the second half of the number word. This change is initiated by a special digit in the " present instruction " word. All such 40-digit words are held within the store in such a fashion that the addresses of the two parts bear a constant and predetermined relationship to one another; in the simplest form the numbers denoting the addresses may differ by one. Thus, whenever the instruction word denotes a 40-digit number the address staticisor unit is appropriately altered at the end of the second action beat by operation of a circuit which is controlled by the presence or absence of a " 1 " at a chosen digit position of the function staticisor. The invention is also applicable to " two-beat" and " three-beat " machines. Moreover, provision for handling 80-digit number words is described. Specifications 645,691, 657,591, 682,156, 705,474, 734,071, 734,073, 734,074, 734,075, and 734,482 also are referred to.

Title: Improvements in or relating to power assisted mechanical transmission linkages
Inventor: HARRISS JOHN HENRY
IPC: F15B13/10
Filed: 1951-09-10
Abstract: 724,755. Fluid-pressure servomotor-control systems. AUTOMOTIVE PRODUCTS CO., Ltd. Sept. 26, 1952 [Sept. 10, 1951], No. 21582/54. Divided out of 724,750. Class 135. In a servo-assisted mechanical transmission linkage applicable to the operation of the flying controls of aircraft and including lost motion for operating the control valve of the servomotor, fluid-pressure operated means is provided which, upon failure of the pressure for operating the servomotor, takes up the lost motion and releases a latch mechanism by which the servomotor is connected to the linkage, whereby direct manual actuation can be effected without movement of the servomotor. As shown the servomotor 205 is pivotally anchored at its lefthand end and has a piston 207 nected to an arm 208 which is rotatable about a shaft 212 on ball bearings. An output member 218, which is pivotally connected to the control surface to be operated at 222, is also rotatably mounted about the shaft 212 on ball bearings and is pivotally connected at 223 to an input lever 224. Pressure fluid, which is constantly applied to the right-hand side of the servopiston 207, has access to a spring-loaded piston 215 which normally holds a three-armed lever 239 pivoted at 241 to the lever 208 in such position that a roller 245 on one of the three arms is held in a notch in a plate 247 which is fixed to the input lever 224. The input lever has an eye 228 with a limited degree of radial freedom with respect to the shaft 212. Thus, actuation of the input lever 224, which rocks about the point 223, operates the control valve 238 of the servomotor through a lever 237 and link 236 which is connected to the eye 228 of the input lever, and the consequent movement of the servopiston operates the output member 218 through the roller 245, plate 247 and the pivotal connection 223 between the input and output members. Should the pressure fluid supply fail the spring 217 loading the piston 215 rotates the three-armed lever to withdraw the roller 245 from the plate 247 so that the servomotor is disconnected from the linkage, and to operate a link 243 which rotates a cage 232, Fig. 4, in a direction to cause balls 233 to move along inclines 231 and take up the radial clearance of the eye 228 of the input lever thereby causing the input lever and output member to be locked together for direct manual operation. Should the supply of pressure fluid be resumed, the parts automatically revert to the arrangement for power assisted operation.
