Title: Improvements in and relating to machine guns
IPC: F41A5/30
Filed: 1917-10-11
Abstract: 198,701. Hazelton, G. Oct. 11, 1917. Machine guns. - The rate of fire of machine guns is increased by providing on the muzzle a piston 2 engaging a cylinder 3 fixed to the gun casing, the piston being acted upon by the gases which are trapped in the space 6 when the projectile is traversing the aperture 5, but which afterwards escape through apertures 7 uncovered by the piston. The rearward movement of the piston and barrel compresses an auxiliary spring 8 which reacts to permit a quick return of the barrel. The spring 8 may be replaced by a spring 9 of the form shown in Fig. 3 which occupies less space when compressed. The leverage of the main spring 13 is increased, as the lock approaches its rearward position, by the engagement of a cam 11 on the fuzee-arm 10 with the linkage 12 connecting the fuzee-arm with the main spring.

Abstract: 603,098. Making cutter bits for chains. NEWTON, E. P. (Frank Prox Co., Inc.). June 14, 1945, No. 15120. [Classes 83 (ii) and 83 (iv)] Die rolling; punches and dies.-A method of making cutter bits for mining machine chains comprises forming on each side of a metal strip or bar, a series of spaced identical projecting members arranged at an angle other than a right angle to the length of the bar and with the projections on one side opposite the spaces of the other side, then punching out the members projecting on one side and thereafter similarly punching out the members on the other side. A bar 50, Fig. 7, is passed between die rolls 52, 53 formed with recesses 56 and 57 respectively so as to form members 37A on one side of the strip, alternating with members 37B on the other side. The formed strip is then fed to a punch comprising a base member 62, Fig. 8, having bars 63 defining ports 64 into which the projections may snugly fit and a punching die 65 having fingers 66 to co-operate with the ports 64, which are arranged at an angle to correspond with the angular set of the projections 37A, 37B. The projections on one side are first punched out and the strip inverted to remove the remaining projections on the opposite side. Cutter bits thus formed may need grinding on their edges and when finished have the shape of a segment of a double convex disc, with a flat face 39, Fig. 3, and two identical convex surfaces 40, 41 meeting in a sharp curved edge 42.

[Class 38 (ii)] A control arrangement to give overload protection of a converter comprises a D.C. circuit fed from an A.C. circuit through a choke and rectifier, the impedance of the choke being varied by means of a saturating winding traversed by a current proportional to the load current, grid control being affected by variations of current in the D.C. circuit. The grid transformer 13 operates at saturation to give a peaky wave and is provided with two groups of saturating windings, one group 22, 23 is connected to a source of variable D.C. 24 to enable the moment of ignition to be varied, the other set 9, 10 is connected to the A.C. circuit 6 through a rectifier 7 and choke 1 to enable overload protection to be effected. The choke 1 has a saturating winding 2 connected in the main converter circuit so that when overload occurs the choke is rendered ineffective and the current through the saturating windings 9, 10 increases to retard the ignition. In a modification to get an amplified effect an additional choke is provided, the saturation of which is controlled by the first choke. Instead of being controlled from the D.C. side of the rectifier, the saturating windings 2 of the choke 1 may either be connected to the A.C. circuit or through a rectifier to a current transformer connected to the A.C. side. In a polyphase arrangement a plurality of transformers B are provided, the various saturating windings 9, 10 being connected in series. Specifications 417,921, 431,784, and 432,106 are referred to.

A method for the continuous incineration of domestic refuse or the like comprises the steps of reducing the refuse to a pulverulent condition, continuously introducing the material into one end of a combustion chamber, maintaining through flow of the particles of refuse through the combustion space by a forced flow of preheated air, causing or supporting combustion by one or more burners within the said chamber, and extracting part at least of the heat of the combustion products and using it to heat the injected air. As shown, the incinerator comprises a loading section A, a combustion chamber B, a heat exchanger C, fly-ash scrubber towers E and a chimney F. The pulverized material is fed by a conveyer 20 into the section A, passing therefrom to the chamber B under the action of a high-velocity nozzle injector 1 fed with heated air under pressure. The hearth 6 of the chamber B incorporates a number of high-pressure air nozzles 7, supplied along with the injector 1 via a compressor 16 and heat exchanger C, which nozzles maintain the pulverized refuse in suspension adjacent burners 8 and direct the incombustible residue across the hearth and around baffle wall 10, the heavy particles falling into water sump 11. In another embodiment (Fig. 2, not shown) the combustion chamber is vertical, the refuse being fed in at the top.

Abstract: Discharge prints on coloured textile fabrics of cellulose triesters (including surfacesaponified cellulose triesters) are obtained by applying an aqueous discharge paste containing a metal formaldehyde sulphoxylate reducing agent such as that of sodium, zinc or barium, a swelling agent for the cellulose ester and a thickener, drying and then steaming either at a temperature above 237 DEG F. under pressure of at least 9 pounds per square inch gauge in which case the safeironing temperature of the fabric is p  also raised or, alternatively, steaming at atmospheric pressure at about the boiling point of water, in which latter case the fabric is also subjected to the action of dry heat, to raise its safe-ironing temperature, before or after the discharging operation.  The "colour" to be discharged may be a dyestuff or a dyestuff component to be subsequently developed, and the discharge paste may also contain dyestuffs whereby illuminated discharges are obtained.  Specified swelling agents are phenylmethyl-carbinol, trialkyl phosphates, b -phenoxy-ethanol, glycol diacetate and methoxy-ethyl acetate.  Specified thickners are oxyethylated locust bean gum, apo gum, British gum and methylated and carboxylated starch.  The paste may also contain humectants such as thiodiethylene glycol, monoor poly-ethylene glycol, glycerol and sorbitol.  Citric or lactic acid and inorganic water binding agents such as titanium dioxide, alumina, silica, fuller's earth, kaolin or bentonite may also be added.
