Abstract: 1,059,499. Altering the structure of metals by mechanical treatment; welding. DEUTSCHE AKADEMIE DER WISSENSCHAFTEN ZU BERLIN. April 24, 1964, No. 17090/64. Headings B3R and B3V. A metal monocrystal is shaped in steps by rolling, drawing, extrusion or the like, so that on heating to the vicinity of the melting point it does not recrystallize and does not exhibit any grain boundary embrittlement, the direction of shaping being found experimentally so that the formation of recrystallization nuclei during shaping is suppressed. Before being rolled, the rolling planes may be ground and/or polished. Intermediate annealing operations, preferably in a vacuum or protective gas atmosphere, may be carried out between the shaping steps, which may be effected above room temperature. The surface layer of the crystal may be removed after the shaping operation. In an example, a molybdenum crystal produced by electronic zone melting, is ground and polished, rolled at room-temperature in steps of 0.003 mm. per pass, and finally polished electrolytically. It is stated that the prevention of recrystallization makes it possible to produce ductile welded joints, preferably by electron beam.

Abstract: 748,755. Parachute release mechanism. REDWING, Ltd. July 7, 1952 [July 24, 1951], No. 17514/51. Class 4. [Also in Group XXVIII] An automatic parachute release device including a piston reciprocally mounted in a cylinder and connected with the rip cord, means containing gas under pressure for actuating said piston to pull the rip cord and a pressureresponsive device for controlling the release of said gas has means for regulating the rate of flow of the gas to the piston. A casing 1 has a cylindrical recess 2 to house a bottle 3 containing gas under pressure. The outer end of the recess is closed by a plug 4 and the inner end communicates with a passage 5 into which the bottle extends. A sleeve 6 is secured in the casing 1 by a screwed plug 7 which clamps a flanged end of the sleeve against an abutment in an extension 5a of the passage 5 and also clamps a flange on a flexible bellows 8 which forms an air-seal for the inner end of the sleeve 6. A plunger 9 is reciprocally mounted in the sleeve 6 and has clamping members 10 and 11 secured to its inner end to opposite faces of the end wall of the bellows 8, the member 11 carrying a pointed needle 12. The opposite end of the plunger has a collar 13 secured thereto which forms one abutment for a spring 14 retained by the end 15 of the sleeve. The plunger is normally held in the position shewn by two sears 16, 17, the former being connected to a static line 18 and the latter being pivoted to a lever 19 pivoted at one end 20 to the casing 1 and at the other end 21 to aneroid capsule 22. A passageway 23 connects the passage 5 with a cylindrical recess 24 in which is mounted a spring-loaded slide valve 25 connected to one end of a rod 27, of which the other end enters a recess 24a, in turn connected to the passage 23 by further passages 28, 29, the passage 28 enclosing an externally adjustable needle valve 30. A further recess 32 communicates with the recess 24 through a passage 40 and houses a reciprocable piston 33 having a piston-rod 34 that extends outside the casing and has a yoke connection with two arms 37 (of which one only is shown in the drawing) having a cross-head connection to a wire 38 which operates the parachute rip cord. When the parachute is launched, the sear 16 is withdrawn automatically and the sear 17 is withdrawn by the action of the capsule 22 at a predetermined altitude. This releases the plunger 9 which pierces the cap of the bottle 3 and admits gas to the needle valve 30 which meters the gas through the passage 29 to the recess 24a until the pressure therein builds up sufficiently to act on the end of the rod 27 and move the valve 25 to a position where the passages 23 and 40 are in direct communication to enable gas pressure to act directly on the piston 33 to cause it to operate the rip cord. Specification 606,708 is referred to.
