Title: Improvements in and relating to the obturating of the breeches of guns
Inventor: PRACHE JACQUES EMILIEN
IPC: F41H7/03
Filed: 1950-03-13
Abstract: 667,639. Ordnance. SOC. DES FORGES ET ATELIERS DU CREUSOT. March 13, 1950. No. 6291/50. Class 92 (ii). An obturator for a gun is in the form of a screen which is in contact with the rear face of the inner tube 1 of the barrel and is movable into and out of the obturating position while remaining in the same plane. The obturator shown consists of two plates 9, 10, pivoted respectively at 11, 12, and secured together at 9b, 9c, so that they move inwards and outwards in unison. A rod 16 connected to the plate 10 is linked to a shaft 20 which is surrounded by a torsion spring tending so to rotate the shaft as to cause' the plates to move to the breechclosed position. The meeting edges of the plates may have co-operating tongues and grooves to ensure a gas-tight seal. The opening of the breech has no effect on the plates, but when a loading arm 7, Fig. 3, is brought to the loading position it engages and moves a lug 29 on a shaft 26 linked to the shaft 20, and the latter is moved to open the plates. The plates are held in the open position by a latch 30, which engages the inner edge of the plate 9. However, the latch is pressed forwards to an inoperative position by the rim of the round when the round is loaded into the chamber, and when the loading arm is moved away the plates move slightly inwards to bear against the cartridge rim, such movement preventing the catch from re-engaging the edge of the plate 9.

Abstract: 786,773. Knitting; finishing fabrics. MELAS HOSIERY CO., Ltd. March 18, 1954 [March 9, 1953], No. 6490/53. Classes 42 (1) and 74 (2). A crepe appearance is produced in an article knitted of a yarn having thermoplastic properties by greatly reducing or eliminating the take-off tension applied to the fabric for the article as it is produced so that a loop structure of irregular formation results. The fabric is then subjected to a setting treatment to set the loops in their irregular formation and subsequently, on completion of the article, the article is subjected to a normal pre-bonding treatment. In the case of a seamed stocking, a stocking blank knitted with the irregular loop formation is subjected to a preliminary heat setting treatment by immersing it for a period in boiling water or conditioning it in a steam atmosphere for a period. Thereafter the blank is dried, seamed and linked and subjected to normal preboarding in a steam atmosphere under pressure for a short time. Specification 676,522 is referred to.

Abstract: 1,079,088. Checking arrangements. INTERNATIONAL BUSINESS MACHINES CORPORATION. Feb. 15, 1966 [April 5, 1965], No. 6494/66. Heading G4A. In a data-handling system, a selected location can be specified for the recipt and/or delivery of data by the generation of a respective address, an error signal being produced if the address is invalid or, independently, if the location is unavailable. A computer can select one of four storage units by supplying the corresponding address to a bus control unit wherein it is checked for validity, producing an error signal if invalid. The same error signal is also produced if the bus control unit power supply fails or if a ready signal is not present from the selected storage unit. The ready signal is produced by the storage unit provided a transistor is not cut-off by either failure of the storage unit power supply or operation of an associated maintenance switch. A modification uses separate transistors for sensing storage power failure and maintenance switch operation. A similar arrangement can also be provided for input/output channels controlling such units as card reader/punch and tape drive.

Abstract: 1,077,522. Typewriters etc. G. MANUS. Feb. 19, 1965 [Feb. 29, 1964], No. 7382/65. Heading B6F. [Also in Division G4] A type-bar is selected by closing the appropriate key switch to energize the associated type-bar-selecting solenoid, all the solenoids being connected to a common current-limiting device which can only provide sufficient current to actuate one type-selecting-solenoid at a time, and after the type selection a common striking mechanism is actuated to effect printing. Selection of type bars in too rapid a succession may be avoided by delaying the triggering of a monostable circuit which supplies the solenoidenergizing pulse, until a given interval has elapsed since the preceding type selection operation. Where selection of a type bar is controlled through a catch attracted by a type selecting solenoid, residual current in the solenoid may be sufficient to hold a catch which has rebounded into contact with the solenoid after a type selecting operation, and to prevent this, an RC circuit may be provided in series with the solenoid to effectively cancel the residual current and return the catch to its inoperative position.

Abstract: 745,833. Gating circuits. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 8, 1954 [March 17, 1953], No. 7410/53. Class 40 (6). [Also in Group XIX] In an electronic digital calculator (see Group XIX) a cold-cathode gas-discharge tube of the type described in the April, May and June, 1952, editions of " Electronic Engineering " is used as a combined bi-stable trigger and a gate. When used as a trigger an input to the tube is applied to its trigger electrode, " input 1," Fig. 1a, which fires the tube, causing a consequential fall in the steady D.C. voltage at # output 1." The trigger can be turned # off " by applying either a positive pulse to the cathode, " Put off 2 " or a negative pulse to the anode, # Put off 1." When the tube is used as a gate, negative pulses are applied to the cathode at " Input 2 " and are passed by the tube to " Output 2 " only when the tube is conducting. In the " logical " symbol representing this circuit arrangement, Fig. 1b, the cathode-anode path is denoted by a vertical line, " Input 2 " to " Output 2." Negative pulses on this line are gated by the tube, i.e. they are passed only if the tube is conducting or " flashed." Flashing and extinguishing inputs are shown and a steady D.C. voltage depending upon the state of the tube can be obtained at " output 1." It is also possible to use this circuit as a gate which automatically closes after a pulse has passed through. Thus when the tube is conducting a negative pulse applied to the anode at " Put off 1," Fig. 1a, will extinguish the tube and a negative pulse will appear at " Output 3." When the tube is used in this manner it is shown as in Fig. 1c, in which, for simplicity, the input and other output leads have been omitted. Specifications 717,114, 745,879, 745,880' and 745,881, [all in Group XIX], are referred to.
