Title: Improvements in or relating to trigger mechanisms for automatic firearms
IPC: F41A19/33
Filed: 1941-04-17
Abstract: 573,462. Automatic guns. TEMPLE, G., SHEPHERD, R. V., and TURPIN, H. J. April 17, 1941, No. 5018. [Classes 92 (ii) and 119] Relates to trigger mechanism for automatic guns of the type in which the backward thrust of the gun gases on the cartridge case causes opening movement of the breech-bolt which is returned by a spring to load and fire the gun. In known mechanism, an actuating lever L pivoted at one end to the trigger J and having a projection L<3> engaging-one arm of the sear K, is employed for transmitting movement of the trigger to the sear and also forms part of means for selecting automatic or single-shot fire. According to the present invention, a spring L<2> is connected between the trigger and one arm of a bell-crank lever K<2> pivoted on the sear so that its other arm K' exerts pressure on the actuating lever L, whereby the spring acts as a return spring for the trigger and sear and also as a biassing spring for the actuating lever. As shown applied to a " Sten " machine carbine, the trigger J is pivoted on a removable pin J<1>, its movements being limited by a pin J<6>. The actuating lever L is freely jointed to the trigger at J<2> and its front upturned end L<4> lies in the path of a projection D<11> on the breech bolt D, the actuator being thus slipped or disengaged from the sear for single-shot fire. The change to automatic fire is effected by a transverse press button L' which acts to move the end L<4> of the actuator laterally clear of the projection D<11> on the breech bolt, the sear being then held away from the bolt when the trigger is kept pulled.

Safety harnesses are formed from two straps 1, 2 or 11, 12 joined by a quick-release buckle 3, 13 and may be arranged on a vehicle seat as shown in the Figures, the path of the straps being along 1a-1f, 2a-2f in Fig. 1, 1a, 1b, 1h 1e, 1d, 1c, 1g and 2a, 2b, 2h, 2e, 2d, 2c, 2g in Fig. 2 and 11a-11f and 12a-12f in Fig. 3. Spring clips 9, 18 which hold the straps frictionally may be used to fasten the straps to anchorages 4, 17. The ends 1f, 2f, 1g, 2g, 11f and 12f are looped by means of adjustable buckles 8, 10, 19 in order to adjust the size of the harness to the seat. The embodiment of Fig. 2 may be modified by looping one or both of the looped parts 1g 2g over the parts 2a, 1a, respectively, instead of to the anchorages 4 (Figs. 5, 6, not shown). The embodiment of Fig. 3 may be modified by using two anchorages 17 and two clips 18 to anchor separately the two straps. Adjustment of the waist straps to suit the passenger takes place at the quick release buckle which automatically adjusts the shoulder straps also.

Title: Metal-phenol-nitrogen compounds
IPC: C09D167/00
Filed: 1947-02-20
Abstract: Resinous compositions, especially coating compositions (e.g for metal articles such as wire) contain a heat-convertible polyester resin obtained by the reaction of a dihydric aliphatic alcohol and a dibasic unsaturated acid or anhydride, and a phenol-soluble complex of a polyvalent drier metal obtained by heating an organic or inorganic compound of a polyvalent drier metal with a phenol and an aliphatic nitrogen compound containing at least one NH2 group.  The complex, which is added to the resin while it is in the fusible state, preferably amounts to 1-10 per cent by weight of the latter, calculated as free metal in the complex, and has the effect of reducing the "hot-shortness" of the product.  The compositions may be further improved by addition of an oil-soluble phenol-aldehyde resin, or, less suitably, an oil-insoluble phenol- or ketone-aldehyde resin, and may be plasticized by addition of non-heat-convertible polyester resin (e.g. a condensation product of a dihydric alcohol and a saturated dibasic acid).  Solvents specified for use in coating compositions are coal tar naphtha, a mixture of ethylene glycol monoethyl ether, cresols and butanol, benzene, toluene, xylene and phenols.  Examples are given in which the resins employed are condensation products of triethylene glycol with the adduct of maleic anhydride and cyclopentadiene, with maleic anhydride and with a mixture of maleic and phthalic anhydrides.ALSO:Complex compounds of polyvalent drier metals are prepared by heating a compound such as the oxide, acetate or carbonate, of a polyvalent drier metal (e.g. lead, manganese, magnesium, cobalt, zinc, iron, vanadium, cadmium, nickel, cerium, thorium or titanium) with a phenol and an aliphatic nitrogen compound having at least one NH2 group.  Suitable amines are butylamine, urea, and alkylene polyamines such as ethylene diamine, propylene diamine, diethylene triamine and the higher homologues thereof. Suitable phenols are phenol and its homologues such as the cresols and xylenols and the ethyl, butyl, amyl and octyl phenols, the hydroxy benzoic acids such as salicylic, the polycyclic phenols and the polyhydric phenols.  The phenol and organic nitrogen compound are preferably present in molar quantities in excess of the co-ordination number of the metal, clear complexes being obtained when the drier metal compound is reacted with a minimum of five mols in all of phenol and nitrogen compound, the quantities being such that four NH2 groups and four hydroxyl groups are present for each drier metal atom.  The products are used as additives for heat convertible polyester resins, and varnish compositions thereof with oil soluble phenol aldehyde resins.  Numerous examples are given.

Abstract: 621,450. Concrete piles. HOLMES, A. B. Feb. 26, 1947, No. 5637. [Class 68 (ii)] In the formation in situ of a reinforced concrete pile, a bore is made with or without the aid of a lining and driving tube 11, a reticulated tubular reinforcement 13 is located within the bore which is then charged with concrete, consolidation of the concrete being effected by vibrating a tube 17 provided with a detachable shoe 16 within the reinforcement, the tube 17 being withdrawn at one or more consolidation steps leaving a shoe 16 to be permanently set within the pile after each withdrawal. Rupture of the concrete shell between the wall of the bore and the reinforcement is prevented by charging practically dry concrete into the tube 17 prior to each withdrawal. On the final filling of the tube 17, a relatively wet concrete 20 is used, to ensure that voids will be filled as the tube is withdrawn. As shown in Fig. 3, a charge of stiff concrete 12 is deposited at the bottom of the bore to provide a hard standing for a metallic anchor plate 14 which may be attached to the bottom of the reinforcement. No anchor plate is needed if a hard standing is provided either by an abandoned driving shoe previously used with the tube 11, or by a rock stratum.
