Abstract: 1,051,856. Reflectors; shutters. NATIONAL RESEARCH DEVELOPMENT CORPORATION. March 9, 1965 [March 12, 1964] No. 10504/64. Headings G2A and G2J. [Also in Divisions H1 and H3] The reflectivity of a mirror having a surface layer of semi-conductor material is varied by a source of intense light. In an application to a laser, Fig. 1 a ruby laser rod 1 is disposed adjacent a flash tube 5 between a plane mirror 2 and a germanium mirror 3. When the tube 5 is flashed the laser will produce bursts, and an occasional burst will be of higher intensity and will increase the reflectivity of mirror 3 thereby increasing the intensity of the burst, and as a result of position feedback a giant pulse is produced. The mirror 3 may be a slab of germanium, a germanium coating on a slab of quartz, or a germanium coating on the rod 1; the mirror 2 may be a coating on the rod 1. In a modification, Fig. 2 (not shown), the reflectivity of the mirror 3 is increased by light from an auxiliary laser 6 operated just after the flash tube 5 by a timing device 7. In another arrangement, Fig. 3 (not shown), the mirror 3 acts in effect as a shutter for a camera 8, the mirror being triggered by a laser beam as in Fig. 1. In a further arrangement (not illustrated) a slab of germanium is placed in a waveguide and acts as a reflector for radio waves when illuminated by an intense source of light.

Abstract: 220,351. Williams, G. H. April 18, 1923. Electrically or pneumatically operated fastenings; latches, sliding. - Railway carriage doors are fastened simultaneously by bolts carried by plates with cam-shaped holes by arms on spindles connected to pinions by a ratchet mechanism permitting rotation in one direction only, and operated by racks. Figs. 1 and 2 show a pneumatically controlled rack. The bolt b is carried by the plate a with an opening engaged by the spring plunger n on the arm g carried by the shaft f which has a ratchet engagement with the shaft h carrying the pinion j. When the cylinder l is exhausted, the piston moves against the spring m, moving the rack k and turning the arm g through 180‹ and causing the spring plunger n to withdraw the bolt. The return of the rack on destroying the vacuum moves the pinion but not the arm. When the cylinder is next exhausted, the arm g is moved a further 180‹, shooting the bolt. Fig. 3 shows the rack k operated by a solenoid p and returned, on interrupting the current, by a spring q. The bolb is operated in this case by a clock-spring arm g carrying a roller s and secured to the plate r on the shaft f. A keyhole v enables the bolt to be withdrawn by a simple key and a keyhole w en. ables the pinion j to be turned by a second simple key if desired. By reason of the resilience of the arm g or plunger n, the doors may be slammed.

IPC: C11B3/06
Filed: 1916-08-02
Abstract: 101,097. Baskerville, C. Aug. 2, 1915, [Convention date]. Fatty oils, purifying; soaps, materials for making.-In purifying saponified oils, particularly cottonseed oil, by treatment with an absorbent material, such as short-fibred cotton-lint, chemical paper-pulp, &c., and alkali, which forms soap with the free acids of the oil, the absorbent material, after separation in a filter-press, is subjected to mechanical pressure so as to expel as much as possible of the oil. The residue is digested with alkali to form soap, which may be dried to a powder. Part of the cotton is stated to be converted into a collodial condition. To facilitate filtration, the oil to be purified may be treated with dehydrating- agents, such as anhydrous sodium carbonate or sulphate, which harden the soap. The cotton, before use, may be moistened with water or alkali. The press residue may be treated with acid to form " black grease."
