Title: Improvements in or relating to electrical height indicating apparatus
IPC: G01S11/02
Filed: 1940-12-30
Abstract: 581,163. Indicating height of aircraft &c CONNELL, W. H. Dec. 30, 1940, No. 18217. [Class 37] Apparatus for indicating the height of an aircraft or other object above a conducting surface, of the type described in Specification 581,161-is provided with means for preventing the presence of moisture from having an adverse effect on the indication. Fig. 1 shows one of a pair of flat plate electrodes which are mounted on the wings of the aircraft or at spaced points on the fuselage. The electrode 5 comprises a thin copper plate secured to an insulating support 6 which projects a short distance from the edges of the electrode. Secured to the edges of the support 6 is a metal frame or screen 7 which surrounds the electrode 5 and through the aperture in which the electrode 5 is exposed. The electrode construction is secured by rivets or bolts 8 to the aircraft body 9. The rear surface of the support 6 has secured to it a copper sheet 10 which maintains a constant capacitance between the electrode 5 and the aircraft body 9 if the support 6 should bend away from the aircraft body during night. A pair of leads 11 passing through insulators 12 are connected to the electrode 5. The frame 7 is earthed to the aircraft body through rivets or bolts 8. The effective area of the electrode 5 is determined by the size of the aperture in the shield 7, which thus prevents increase of effective area due to deposition of moisture on the support 6. Fig. 3 shows the application to torpedo shaped electrodes. The electrode 13, formed of thin sheet metal, is suspended from the fuselage 14 by a pair of rods 15 serving as electrode leads. These rods pass through metal bosses 16 attached to the electrode 13 and pass through insulating sleeves 17 which insulate the electrode 13 from the fuselage. Insulators 20 are provided at the upper ends of the rods 15 and surround nuts 21 which clamp the assembly to the fuselage. Conducting sleeves or cowls 22, earthed to the metal parts of the aircraft, are spaced apart from the insulating sleeves 17 and are arranged to overlap the metal bosses 16. The cowls 22 form shields defining the effective area of the electrodes should moisture accumulate on the insulators 17. In a modification the electrodes are suspended by arms which pass through open apertures in the aircraft body, the portions of the body that surround the arms serving as shields.

Abstract: 388,412. Making nuts, bolts, rivets, screw-blanks, &c. WILCOX, R. L. and WATERBURY FARREL FOUNDRY & MACHINE CO., Waterbury, New Haven, Connecticut, U.S.A. June 24, 1931, No. 18305. [Classes 83 (ii) and 83 (iv).] Forging-dies.-In making nuts, bolts, rivets, screw-blanks, &c., a blank is pressed into dome form at one end and then pressed, while free to flow out laterally, so as to produce a polygonal form. A cylindrical blank is cast or cut from a rod and given a ball or domed shape 111, Fig. 3, by pressing between dies 26, 27. The blank is then placed in a matrix 13, Fig. 5, supported on a spring 131, and having a hexagonal passage 14, and is flattened by dies 31, 32 which form central recesses 12 therein and leave the outer portion unacted on so that it forms a chamfered edge. In a modification a blank, domed at one end only, is placed in a shouldered matrix 36, 37, Fig. 11, so that a collar 112 is formed on the lower end. The blank is then punched. In other modifications the domed blank may have flats 123, Fig. 23, on its end face or 122, Fig. 22, on its sides. Drawing-dies.-In making a bolt a cylindrical blank 18, Fig. 16, may have a part of its length reduced by pushing through a die 20 and is then given a domed head 21, Fig. 24, by a die 27 and, if desired, a point 142 by a die 42. Dies 32, 37, Fig. 25, and a matrix 47 then give the desired shape to the head. The ejector 45 serves to prevent movement of the blank during upsetting. A screw-thread may then be rolled on the shank or reduced part.

Abstract: 1416836 Modulating light SUWA SEIKOSHA KK 26 April 1974 18333/74 Addition to 1338739 Heading H4F In a display cell comprising a layer of remote liquid crystal material between two electrode structures, the electrode structures are spaced by a peripheral film of adhesive bonded therebetween, e.g. by heating, and a film of resin material is disposed on each structure and in contact with the remote layer, the resin preferably having a softening (or decomposition) point higher than that of the adhesive. As described, each resin film is rubbed so as to produce a "twist" cell with voltage controlled optical activity, and it is said that the remote molecular alignment produced by the rubbing is more uniform than that obtained by rubbing the electrode structure itself. The adhesive may be based on epoxy resin, silicone, polyethylene, polyester, polyolefin, nylon, or polyamide materials, or may be an adhesive for glass. The resin may be a fluoroplastics (e.g. PTFE), polyvinyl alcohol (PVA), polyester, polyamide, silicone, or polyimide polybenzimidazole resin material. A PTFE resin may be used with a polyester adhesive, or a PVA or polyester resin with a nylon adhesive. The electrode structures are segmented transparent conductive films on glass substrates.
