Title: Improvements in or relating to anti-backlash bolt assemblies
IPC: B64C13/02
Filed: 1953-03-31
Abstract: 743,267. Bolting; hinges. NORTHROP AIRCRAFT, Inc. March 31, 1953 [May 31, 1952], No. 8880/53. Classes 65 (2) and 89 (I). [Also in Groups XXXIII and XXXIV] A hinge-bolt assembly for insertion in a bcre comprises a bolt, sleeve-means slidable on the bolt and in the bore, at least one ring of elastic material around the bolt and having an outer diameter substantially the same as the sleeve, and means for forcing the sleeve to deform the ring laterally against the bolt and the bore wall to bind the bolt in the bore. The assembly is shown applied to the hinging of an aircraft control surface A, Fig. 3, the bolt having a head 40, shank 41 and a reduced-diameter threaded end 42 for a locknut 51 and washer 50. Sleeves 44a ... 44c are fitted on the shank and separated by pairs of rings 45, e.g. of silicone rubber. The assembly passes through aligned bores 32 in a U-shaped bracket fixed to the surface A, and engages, between the arms 22 of the bracket, selfaligning bearing 28 comprising an outer member 26 having a part spherical track 27 engaging a similar track on an intermediate member 28 between which and an inner member 30 are rollers 29, said bearing being carried by an arm 6 forming part of a hydraulic servomotor for moving the aileron. On tightening the nut 51, the sleeves deform the rings to engage the shank and walls of the bores and eliminate backlash. The sleeves and rings are preassembled on the bolt and held by a cross pin 47, Fig. 4, engaging a notch 46 in sleeve 44c. In an alternative construction, e.g. for binding the bolt in bores 32 only, the assembly comprises a bolt 60, Fig. 6, receiving, on reduced-diameter parts at both ends, rings 62 and sleeves 64 which are caused to deform the rings when nuts 67 are tightened. The bolts are of such length that the washers 51 do not engage the bracket.

Filed: 1916-06-24
Abstract: 163,339. Skipwith, H. L. d'E., and Sandford, F. H. June 24, 1916. Mines, marine.-Relates to automatically-moored mines of the kind in which the mine rises to its appointed depth after sinking to the bottom with the sinker or anchor containing the mooring rope drum, the paying-cut rotation of the drum being stopped by a spring pawl when a wire controlling it and paid out from a drum carried by the mine is made taut by the locking of this drum by a depth-regulating device. According to the invention, the drum 2, Fig. 1, carried by the mine for paying out the wire 1 is stopped by a pawl 8 controlled by an hydrostat 3 and a balance spring 5 interconnected by a lever 7, the fulcrum 9 of which can be adjusted for the desired depth. The lower end of the wire 1 is attached to an arm 10, Fig. 2, which is normally kept down by a spring 11 in the path of a projection 12 on the spindle 13 of the pawl 14 in the sinker, but is lifted by the pull of the wire 1 when the drum 2 is stopped; the pawl 14 is then moved to lock the ratchet wheel 15 of the mooring rope drum 16 bv a spring 17 acting through a projection 19 rigid with the pawl.

Abstract: 1,131,344. Ornamenting. C. GARNETT. 21 Feb., 1967 [1 March, 1966], No. 8967/66. Heading B6G. '[Also in Division C7] An electrolytic marking device M comprises a conductive backing piece 10 carrying on one surface 13 an insulating material 15 formed into a raised pattern corresponding to the desired mark. Preferably the pattern is a mirror image of the mark and the insulating material is absorbent to soak in electrolyte or merely capable of retaining a surface layer of electrolyte in electrical contact with the backing piece which may be of metal or conductive plastic. To make the device, a conductive adhesive material 14 is printed on to the surface 13 in a mirror image of the mark and an absorbent insulating material 15 e.g. glass or asbestos fibre blown thereon. The surface 13 may be formed with recesses (16, Fig. 2) for holding in the insulating material to stand proud of the surface, or with raised portions (17, Fig. 4) to which the insulating material is secured by adhesive (18). Alternatively (Fig. 5), a layer of non-absorbent insulating photo-sensitive lacquer (20) is applied to the surface (13c), a mirror image of the mark is printed on to the lacquer and developed to leave bare the surface in channels (21) and the lacquer standing proud as a mirror image negative of the mark whereby the electrolyte is retained in the channels (21) by capillary attraction or within further raised absorbent insulating material (15). In operation, the backing piece 10 of the device M is connected by a lead 12 to one terminal of an A.C. supply, the other terminal being connected by a lead 12a and clip 12b to the workpiece W.

Title: Semiconductor devices

Filed: 1972-04-25
Abstract: 1358275 Semi-conductor devices FERRANTI Ltd 25 April 1972 [8 April 1971] 9050/71 Heading H1K A semi-conductor diode 10 is formed by epitaxially depositing a N+ layer 12 on a N region 11 in which a P+ region 14 is diffused to define a PN junction 15 extending to surface 13 which is reverse biased during operation. Simultaneously two further P+ regions 16, 16<SP>1</SP> are diffused into region 11 to extend to the surface spacedly from the junction 15. The continuations of P+ regions 14, 16, 16<SP>1</SP> into layer 12 at 17, 18, 18<SP>1</SP> are P-type and the remaining parts of the layer are N+, and the opposite surface 19 is doped to N+ region 20. Contacts 22, 23 applied to regions 14, 19, complete the diode. A passivating layer 24 of SiO 2  is formed during diffusion over the surface extending from PN junction 15, and the surface layer N+ doping discourages reversion to P-type. A high breakdown potential is achieved, which may similarly be obtained in a transistor or SCR with a reverse biased PN junction. The N + region may be within P + region 1 and the N region may be formed by diffusion into the P+ region, while the further P+ regions may be diffused into the N+ region. The N+ region may be diffused instead of epitaxially deposited.

Abstract: 107,586. Reeser, W. E., and Rycken, W. May 2, 1916, [Convention date]. Embossing; embossing-surfaces.-A process for reproducing paintings, pictures, maps, wallpapers &c. in full detail on canvas, linen, or other textile material consists in coating the canvas &c. with glue and then with an opaque covering, printing it in one or more colours with a copy of the original picture and then pressing it on to a specially prepared matrix or die of hardened plastic material bearing an impression of canvas markings and the brush marks and other raised parts of the original. The process is carried out in the following manner. A piece of canvas. linen, or other textile material is coated with glue or gelatine and then provided with a white opaque coating preferably composed of kaolin or chalk and gelatine and glycerine. This coating is smoothened by pressure and then printed in one or more colours with a copy of the original painting &c. The printed canvas is then pressed upon a grained plate to produce canvas markings. The brush marks and other characteristic ieatures of the original are then applied by an artist by means of a brush using a paste of shellac dissolved in alcohol, and white lead. The canvas pattern may then be passed through an alum bath to harden it and, after drying, is coated with shellac, and an impression of it is taken in a cake of plastic material capable of subsequent hardening such as a mixture of kaolin, glue, glycerine and alum to pro. duce the matrix or die. The canvas or other textile material on which the reproductions are to be made is coated with glue or gelatine and the opaque coating as in the preparation of the canvas pattern and is printed in one or more colours with a copy of the painting &c. It is then moistened and impressed on the matrix to reproduce the canvas, brush, and other marks, and, after drying, is varnished in the usual way.
