Abstract: 854,516. Ordnance. ABRAMSON, H. July 12, 1951 [Aug. 4, 1950], No. 16589/51. Class 92. A recoilless gun with a barrel 1, for projectiles with a driving band, has no breech closure and has a chamber with one or more tapering supporting surfaces 5, 6, for the driving band or bands. Further, a circumferential seat 4 is provided to fit around the cartridge case, the seat being of such size and shape, and having such surface qualities as to retain, through friction, the cartridge case during the greater part of the time of combustion of the powder in the cartridge. The arrangement is preferably such that, due to the rise in pressure, the case is jammed in the chamber until the pressure has first risen to a maximum value and subsequently dropped to a lower value. The case is then ejected to the rear by the back pressure of the residual gases. In another construction, Fig. 2 (not shown), only one tapering surface is provided, and at the rear of the chamber 4 thus is provided a widening nozzle-shaped expansion funnel. Specification 854,517 is referred to.

[Also in Division D1] A method of bonding together strands or particles of thermoplastic material comprises filling a combustion chamber with an assembly comprising a layer of the strands or particles and a superposed layer of a cellular material, closing the chamber and admitting into it a combustible gaseous medium and effecting ignition of said medium to generate sufficient heat to fuse the particles or strands together where they touch. The strands which may be in the form of filaments, staple fibres, yarns or cords and are optionally knitted or woven and the particles may each be made of thermoplastic material, e.g. polypropylene, nylon or polyvinyl chloride or of non-thermoplastic material, e.g. rayon coated with a thermoplastic material. The cellular material may be a metal gauze, a perforated plastics material or a foam, e.g. polyurethane foam. In the example, a web of polypropylene fibres is placed on a sheet of reticulated polyurethane foam, the resultant assembly being rolled, placed in a cylindrical pressure vessel in which a mixture of oxygen and hydrogen is ignited, the assembly being removed, unrolled and the polypropylene web removed from the foam.

Abstract: Dibenzanthrone dyes dyeing in grey, and blue to black shades, are made by treating dibenzanthrone or its halogenated derivatives with a strong oxidizing agent in the presence of aqueous nitric acid.  As oxidizing agent, potassium dichromate is particularly suitable; other salts of highly oxygenated acids or peracids or their anhydrides, and peroxides may be used.  In examples (1) dibenzanthrone is heated with potassium dichromate and nitric acid (75 per cent); the product dyes greenish-black shades; and (2) pentachlordibenzanthrone (made by chlorinating dibenzanthrone in molten phthalic anhydride) is heated with potassium dichromate and nitric acid (10 per cent).  In a further example, cotton is dyed in a caustic soda-hydrosulphite vat with the product of example 2. Specifications 251,313 and 278,112, [both in Class 2 (iii), Dyes &c.], are referred to.

Title: Logic circuits for solving boolean functions

Filed: 1974-04-18
Abstract: 1466466 Logic circuit SIEMENS AG 18 April 1974 [26 April 1973] 17153/74 Heading G4A A logic circuit solves Boolean functions involving AND and OR operations on a series of binary signals in accordance with instructions specifying AND and OR operations and, includes a first bi-stable circuit 1 set by binary "1" signals and reset by binary "0" signals, a second bi-stable circuit 2 set by a binary zero signal, arranged when set to block the subsequent setting of the first bi-stable, and arranged to be reset by an OR instruction, a third bistable circuit 3 set by an OR instruction if the first bi-stable is set, and an OR gate 8 providing an output in response to the states of the first and third bi-stable circuits. Two embodiments are described. In both cases a series of binary signals a-n are presented in parallel and are clocked to the first bi-stable 1 in series via line LL by pulses L a -L n  and clock T. An instruction signal V is supplied between the supply of the binary signals, V = 1 indicating an OR operation and V = 0 an AND operation. In the first embodiment given an AND operation gate 7 is blocked and bi-stable 1 is set by binary 1 signals. Should a 0 signal occur bistable 1 is reset, and bi-stable 2 is set thus preventing, via gate 4, bi-stable 1 from being set by subsequent binary signals. The AND function is thus fulfilled. If an OR instruction occurs, V = 1, bi-stable 2 is reset so that a subsequent binary "1" signal may set bi-stable 1. Further gate 7 is enabled so that if bi-stable 1 is set, indicating a preceding fulfilled AND condition or a preceding single binary 1 following an OR instruction bistable 3 is set. The output 9 is derived from OR gate 8 and the circuit thus solves functions such as: in the form: The second embodiment Fig. 2 (not shown) is arranged to deal with parentheses and includes an up-down counter which counts up one for each opening bracket and down one for each closing bracket. The contents of the counter are fed into a store both when an OR instruction occurs and bi-stable 1 is set, and when a binary "0" signal occurs. A comparator provides signals when the count in the counter is less than and equal to that in the store, the signals being used selectively to reset bi-stables 2 and 3 to take account of parentheses. Within a single bracket pair parentheses are imposed as in the first embodiment, i.e. A AND B OR C is given as (A AND B) OR C.

Abstract: 226,747. Fairweather, W. C., (Carbonit Akt.-Ges.). July 18, 1924. Mines, marine.- Relates to moored submarine mines such as are pirovided with a drum driven by a propeller under the control of an hydrostat for winding or unwinding the mooring cable to maintain the mine at a given depth in a tideway. According to the invention, the hydrostat c is relieved from the work of operating the clutch and only displaces a tappet m or m<1> by means of arms l, l<1> on its spindle k. The displaced tappet m or m<1> is then operated by a rotating cam p or p<1> driven through a worm gear e by the shaft d of the propeller b. This operation of the tappet brings a clutch q against a bevel wheel g or h, which transmits rotation in one direction or the other to the drum A of the mooring cable, the bevel wheels g, h being driven by a bevel wheel f on the shaft d of the propeller b. At each revolution of the cam, the tappet is restored to its neutral position, and the action is repeated or reversed or suspended, according to the position of the hydrostat.

Abstract: 1,062,911. Storage bunkers discharging. R. HORSFIELD & CO. Ltd. July 29, 1964 [Aug. 2, 1963; Sept. 5, 1963], Nos. 17367/63 and 35098/63. Heading B8E. An even flow of material is produced on a conveyer 7, Fig. 1, by a plough 17 which moves longitudinally of a delivery conveyer 8 deflecting material into a bunker B and opening discharge doors 3 in the bottom thereof. The bunker B is made up of standard sections bolted together end to end without dividing walls between. The V-shaped bases have doors 3 operated hydraulically. A belt weigher 14 weighs the material as it moves towards the plough and may be used to control the movements of the plough as described in Specification 1,062,912. The plough has a curved share 18 and is moved along rails from end to end of sections A, B, C by a cable 19 and pulleys 20, 21. Material ploughed off the conveyer 8 above section C goes straight on to the conveyer 7. Section A has a shoot 25 and a belt scraper for fires. If material is being delivered too quickly by the conveyer 8, the plough moves from right to left, crossing doors 3 as it goes and allowing the surfaces to fill up the bunker. If the supply rate decreases the plough begins to move from left to right, opening doors as it goes to supplement the flow from material previously bunkered. In a second embodiment a line of trucks W, Fig. 9, replaces the conveyer 7. The plough moves from right to left, at a speed controlled by the belt weigher, and fills up each bunker with sufficient material to fill the waggon below it. Subsequently, the plough moves rapidly from left to right and opens all the doors discharging the material into the trucks. Alternatively, all the doors may be simultaneously and manually opened. Materials may be blended by having two adjacent bunkering systems supplying a single conveyer or line of trucks.
