Title: A process for the simultaneous manufacture of primary sodium phosphate and boric acid
IPC: C01B25/30
Filed: 1934-08-30
Abstract: Boric acid and primary sodium phosphate are obtained by treating an aqueous solution of borax with orthophosphoric acid, crystallizing the boric acid formed, separating it from the mother liquor and treating the mother liquor for the recovery of the primary sodium phosphate.  According to an example, an aqueous solution of borax was treated while stirring with 65 per cent phosphoric acid at a temperature of 70  DEG  C.  Boric acid was crystallized by cooling to 10 DEG  C., and separated from the mother liquor by centrifuging. The mother liquor was freed from residual boric acid by treatment with steam and primary sodium phosphate was then crystallized out. The final mother liquor may be re-used.  The boric acid which may contain a small proportion of primary sodium phosphate may be used in the manufacture of glass.

Abstract: 1,103,439. Gas lasers. SHIMADZU SEISAKUSHO Ltd. 27 May, 1965, No. 25027/65. Heading HlC. In an He/Ne gas laser, laser transitions to the 2P 4  level of Ne are enhanced by heating the gas to 500‹ K, thereby providing easier decay from the 2P 4  level to the 2P 6  ground level. In Fig. 1, the gas is heated by an electric heater 13 having a reflector 14. In Fig. 2 (not shown), the laser is mounted in a hermetically sealed case (15) and a thermostat (24) is provided. Ordinarily, Ne atoms in the 2P 4  state (J = 2) reach the 2P 6  ground state (J = 0) via the 1S 2  or 1S 4  states (J = 1) and some atoms enter the IS 5  state (J = 2) from which transition to the 2P 6  ground state is forbidden. By raising the temperature of the gas the atoms in the IS 5  state may be excited to the IS 4  level from which they decay to the 2P 6  ground state.

Title: Improvements in automatic fire arms
IPC: F41A19/03
Filed: 1959-07-21
Abstract: 869,053. Automatic firearms. FABRICA D'ARMI P. BERETTA S.p.A. July 21, 1959 [July 21, 1958], No. 25060/59. Classes 92 and 119. Relates to a firing mechanism for automatic firearms in which there is an extended delay between actuation of the hammer and its striking of the firing pin such that the repeated operation of the firearm is considerably slowed down and also to means for varying such delay. As shown, the hammer 8 Fig. 1 is pivotally mounted at 7 on a member 6 pivoted freely on a bush 4 fixed to the gun casing and having an extension 17 adapted to be engaged by a projecting portion 16 of the breech block 1 as it slides forward. A pivot 9 fixed on the hammer supports the end of a rod 10 carrying the main spring 11, the other end passing through an aperture 13 in the gun casing 12 so as to permit pivotal movement of the rod and spring. In the position shown in Fig. 1 the pivot 9 is below the dead centre position in relation to pivots 7 and 13 and the spring urges the hammer away from the breech block to the position shown. As the breech block slides forwardly, the member 6 is swung anti-clockwise, the pivot 9 passes through the dead centre position Fig. 2 (not shown) whereupon the hammer is forced by the spring towards the breech block with a progressively but slowly increasing thrust to the final position shown in Fig. 3. The bush 4 is mounted eccentrically on a pin 3 fixed to the gun casing and is provided with a hand lever 5 by which the bush 4 can be rotated. Such rotation displaces the centre of the bush 4 so as to charge the moment at which the extension 16 strikes the extension 17 and thus vary the delay. In a modification the part 12 with the pivot 13 may be made movable and be lowered during the closing movement of the breech block instead of the part 6 being raised, the result being to bring the pivot 9 above the straight line through the pivots 7 and 13 as before.
