Title: Improvements in or relating to cartridge feed mechanism for automatic fire arms
IPC: F41A9/54
Filed: 1941-03-05
Abstract: 573,751. Cartridge-feed mechanism for machine guns. COLT'S PATENT FIRE ARMS MANUFACTURING CO. March 5, 1941, No. 3028. Convention date; March 22,1940. [Class 92 (ii)] Relates to mechanism for feeding cartridges carried in rigid or chain strips particularly to heavy machine guns of the kind described in Specifications 226,197, 235,591 and 235,592, [all in Class 92 (ii)], and in U.S.A. Specifications 1,692,328 and 1,692,277. According to the present invention, the reciprocating feed slide of the gun has two separately pivoted pawls extending in opposite directions from their pivots in interfitting relationship, the pawls engaging feed slots in the strips and being spaced apart a distance equal to the spacing of the cartridges in the strips. Fig. 15 shows the transversely reciprocating feed slide 46 at the beginning of a feeding movement with a pawl 47 pivoted thereto at 47a engaging a feed aperture 42e in a rigid feed strip just outside the feed box and a second pawl 48 pivoted at 48a and extending in opposite direction to pawl 47 to engage the next aperture 42e in the strip at a position just inside the feed box. The pawls can be simultaneously disconnected by pressing a button 49. The Figure shows a charged strip B entering the feed box on a loading tray 14 and an empty strip A leaving the feed box. The rigid strips shown are those described in Specification 573,766, the cartridges being moved downwardly to loading position from clips 42c by cams 43b on the feed box. To prevent over-feeding of a strip, a stop-pawl 72, Fig. 5, pivoted in the feed box at 72a engages teeth 42f in the side of the strip and return movement of the strip is prevented by a similarly mounted retaining-pawl 73. The stoppawl 72 is released by a bevel 46e on the feed slide during automatic feed. As shown in Fig. 25, the mechanism is also applicable to feeding articulated link strips of the kind described in Specification 573,766 arranged in a magazine, as described in Specification 573,765, which is fastened to the feed box by the readily-releaseable spring catches 15 used for attaching the loading tray 14. The empty chain strip passes from the gun by way of shoot 99. The feed slide is reciprocated automatically during the action of the gun by a lever 57, Fig. 5, pivoted. at 57a, the end 57b of which engages a recess 50c in a block 50 removably attached to the slide. The rear end of lever 57 is engaged by a bellcrank 53 actuated by a pin 55 on a lever 51, Fig. 4, pivoted at 51a and engaged by a pin 59 on the barrel extension 18. The return stroke of the lever 57 is effected by a spring plunger 58. The feed slide can be manually operated for starting the feed action by pawl means engaging a pin 50d on the slide. For this purpose a plate replacing the usual top cover carries a slide 103, Fig. 19, moved rearwards by a handle 105 to cause a spring-controlled pawl device 111 to engage the pin 50d which escapes from the pawl to permit return of the feed slide after a feeding movement.

Title: Process for producing ornamental markings or decorative effects on materials of celluloid-like character
IPC: B44F9/02
Filed: 1932-02-01
Abstract: Impressions in high relief of the grain and markings of wood are produced on sheet material made from cellulose derivatives, or from artificial resins which have a certain plasticity in the cold state or are thermoplastic, e.g. polymerized vinyl derivatives, by pressing the material, preferably warmed, on to wooden plates so that the material is forced into the pores of the wood.  The material may be in the form of discs or plates, or it may consist of a powder or paste which is formed into a plate by the pressing operation; the plastic condition may be produced by applying heat or by the use of solvents or solvent vapours.  The surface of the wood may be dyed so that colour adheres to the high parts of the celluloid &c. plate, the remaining parts of which are preferably coated with a contrasting colour such as gold or silver bronze. To facilitate detaching the sheet, the surface of the wood may be treated with a solution comprising proteins, fats, oils, resins, or cellulose derivatives.

Title: Improvements relating to neutronic reactor fuels
IPC: C22C28/00
Filed: 1957-02-01
Abstract: Reactor fuel elements consist of an alloy of U 235 with a metal having a low neutron capture cross section such as Al or Zr, the alloy containing a finely divided uniform dispersion of a material such as B which has a high neutron capture cross section but which transforms, on absorbing neutrons, to a material having a low neutron capture cross section.  Preferably the amount of U 235 in the alloy is 15-23 per cent and the alloy contains natural B in the range 0.1-0.5 per cent.  Material enriched in B10 may be used in place of natural B in which case the range of proportions for this material may be reduced.  The alloy may be made by bubbling BCl3 gas through a bath of molten Al at a temperature of about 800 DEG C. U is then added, and the bath temperature increased to 900-1100 DEG C. to melt the U and incorporate it in the alloy.

[Class 38 (ii)] In means for producing grid voltage impulses of adjustable phase for controlling mercuryvapour rectifiers and comprising a variably saturated transformer as described in the parent Specification, inequality of the amplitude of the impulses due to the variation in steepness at different parts of the primary current wave when the latter is sinusoidal is avoided by distorting the primary current into a triangular shaped wave. Such a wave with the apex over the middle of the base may be produced by introducing the third harmonic by connecting a choke 12, Fig. 3, having a saturated core limb in series with the transformer primary 11. A triangular primary current wave having its apex displaced to give a steep slope at the commencement of the wave may be produced by premagnetizing the choke with D.C. or by providing the transformer 20, Fig. 5, with a magnetic shunt 24 either in the form of a permanent magnet or pre-magnetized by a D.C. winding so as to introduce the second harmonic into the primary current in the winding 21.
