Title: A new, or improved, device for securing work to benches and the like
IPC: B25H1/00
Filed: 1922-02-22
Abstract: 194,120. Burt, H. R. Feb. 22, 1922. Vices.-A device for holding the work against the edge of a carpenter's &c. bench comprises a metal plate A adjustably secured to the underside of the bench B and provided with a turned-up end A<a> to which is secured a wedge C coacting with a slidable wedge D for gripping the work against the edge b of the bench. The plate A and its upturned end A<2> may be provided with projections or ribs a, a<2>, engaging corresponding recesses or grooves in the underside of the bench and in the outer wedge C, which latter may be fixed to the plate by screws c<1>, and the two wedges may be slidably connected by a groove and tongue c, d. For adjusting the distance of the clamping wedges from the edge of the bench, the plate A is provided with a slot a<4> and a series of recesses a' adapted to be engaged by the head of a bolt G passing upward through a hole in the bench and fitted with a wing- nut g<2>. By loosening the latter, the plate A may be slid on the shank of the bolt.

Title: Improvements in nut-locking or like devices
IPC: F16B41/00
Filed: 1931-02-19
Abstract: 360,304. Bolts and nuts; bayonetjoint fastenings. BRUN, A., 103, Rue Notre-Dame-des-Champs, Paris. Feb. 19, 1931, No. 5262. Convention date, Feb. 24, 1930. [Classes 44 and 89 (i).] In a safe locking device for screw fastenings which is also applicable to bayonet - joint fastenings, the nut 1 to be screwed up is of cylindrical periphery and is covered by a sleeve 2 on which are formed the usual flats. Rotation of the sleeve 2 causes lugs 5 thereon to engage a spring-pressed cross-bar 3 on the nut. The bar 3 is arranged to be pressed in by the action of bosses 6 on a ring 14 rotated by pins 13 on a barrel 10 connected to the sleeve 2 by a spring cotter 17 engaging one or other of two opposite grooves 18, 19 in the barrel. The position of the barrel to engage one or other of the grooves with the cotter 17, and therefore the position of the bosses 6 to one side or the other of the lugs 5, is determined by the use of a key 11 of any suitable kind, so that when the barrel is so set that the nut can be screwed up, opposite rotation of the sleeve 2 causes the bosses 6 to engage the bar 3 in advance of the lugs 5, so that unscrewing cannot be effected. On the other hand, setting the barrel so that the nut can be unscrewed prevents screwing up. The bar 3 may be replaced by one or more segmental members.

Abstract: 294,927. Mailliet, P. R. Aug. 1, 1927, [Convention date]. Portable hand pumps.-In an atomizer for toilet purposes, in which an air-pump body 7 is surrounded by a liquid receptacle 20, the liquid is ejected through the tube 21 and atomized by a stream of air blown transversely past the mouth of the tube and through an outlet orifice 23 formed in a ring 4 of truncated conical form fixed to the outside. The piston 1, which carries a cup leather 16 is pressed down against the action of a spring 5 to force air past a spring-pressed valve 12 and through a tube 9 into the air chamber 10 at the top of the container 20. When not in use, a screwed socket 1<1> on the piston is screwed on the threaded block 2<1> so that a conical ring 3 engages the ring 4 to close the orifice 23. A cap 6<1> on the piston is provided with a vent 6 which is closed by a finger while the apparatus is in use but. acts as vent to relieve pressure when out of use.
Patent GB-546366-A (GB)
Title: Improvements relating to the reduction of surface reflection
IPC: C03C15/00
Filed: 1941-04-25
Abstract: 546,366. Reducing surface reflection. BRITISH THOMSON-HOUSTON CO., Ltd. April 25, 1941, No. 5345. Convention date, April 26, 1940. Drawings to Specification. [Class 97 (i)] Surface reflection from lead or barium glass is reduced by treating the surface to produce shallow depressions which cause scattering of reflected light and then treating the surface with an acid to produce a film having a thickness about one quarter of the wave length of light and a refractive index between that of the body and air. The surface may first be ground and then etched, repeatedly with hydrofluoric acid which removes minute sharp projections and widens narrow cavities, so that smooth concavities are produced, which scatter reflected light. The etched surface, with or without the opposite smooth surface, is then provided with the required film, which may be produced by immersion in nitric or acetic acid which removes the metal constituent and leaves a film of silicon dioxide. Glass so treated does not show colour when illuminated by ordinary polychromatic light. In a modification, the etched surface, in this case comprising elevated portions, is produced by rubbing the surface with ferric stearate or paraffin wax while hot, and then treating with concentrated hydrofluoric acid. The film on the etched surface is then produced as before. In another modification, an etch consisting of irregular ridges is produced by coating the surface with water and treating with hydrofluoric acid for a considerably longer period without agitation. The film is then produced as before.

Abstract: 530,369. Compound sheet materials. EDWARDS, A. E. Feb. 17, 1939, No. 5423. Convention date, Feb. 17, 1938. Drawings to Specification [Class 140] Electric insulation consists of a thin layer of mica having on one or both sides a web, mat, or fabric of fibrous glass. The glass fibres may be produced as described in Specification 428,720, [Group XXIII], and maybe formed into a matted web by depositing them in haphazard criss-cross relationship on a conveyer belt. A small amount of starch, agar agar, casein, latex, or resin may be applied to bind the fibres, or the web may be strengthened by tensioning as it leaves the conveyer. The web is laid against and bonded to a layer of mica splittings, a similar web being subsequently applied to the other side, if desired. The compound sheet may be calendered and impregnated or coated, e.g. with insulating varnish. A compound sheet consisting of a mica layer covered on both sides with a fibrous glass web or cloth may be split in half through the mica splittings to produce two compound sheets.

A method of measuring the movement of an upper layer 2 of ground which may be subject to slipping over a lower layer 3 comprises placing a bendable rod 7 so that it extends downwards through the upper layer and has its lower end firmly fixed with respect to the lower layer and measuring the angular deflection of the upper end of the rod after a period of time in which the rod has bent as its upper end moves with the moving layer A bore 5 is sunk through the layers 2, 3 and a slip region 4 and a plastics casing 6 is inserted in the bore. The lower end of the rod 7, which may be of steel or a narrow concrete pile, is firmly embedded in the bottom of the bore and the rod extends upwards to a shallow concrete wall 8 at the surface.

An inclinometer or tiltmeter 12 such as a bubble level containing an electrolyte in which a number of electrodes are immersed is mounted on the upper end of the rod. The electrodes are coupled in a bridge circuit and a cover 13 is provided with a connecter 14 to which cables can be attached for conducting a signal from the tiltmeter to any convenient location.
