Title: Improvements in or relating to vibration dampers
IPC: F16F7/04
Filed: 1936-07-11
Abstract: 478,063. Vibration-dampers. ANDRE (COMPONENTS), Ltd., and TRIER, V. A. July 11, 1936, No. 19278. [Class 108 (iii)] Vibration-dampers for vehicles comprise hydraulic and frictional damping mechanism operating simultaneously, the frictional mechanism being controlled from a distance without affecting the damping action of the hydraulic mechanism. A known hydraulic damper comprises a vane B in a casing A secured to the sprung part of the vehicle. The vane B is mounted on a shaft C passing through a boss A<1> of the casing and on which is mounted an arm D connected to the unsprung part of the vehicle. Plates F, F<2> connected respectively to the arm D and a bolt F<3> on the casing surround the boss A<1> und alternate with friction plates G. The pressure between these plates is controlled by an annular tube H, the fluid pressure in which is controlled by means of a pipe M. In a modification the hydraulic damper comprises a piston in a cylinder. In a further modification the two parts of the friction damper are connected to two arms and the piston of the hydraulic damper is connected to one arm and the cylinder to the other. Specification 454,098 is referred to.

Abstract: 646,574. Hand-irons. SILEX CO. July 18, 1947, No. 19323. Convention date, Nov. 5, 1940. [Class 138 (ii)] In a steaming and pressing iron the ironing surface of the sole-plate 11 has a recess 15 having a surrounding depression 17 at its mouth, grooves 22 extending from the recess and a closure 16 for the recess having means for directing steam into the grooves 22. The soleplate 11, Fig. 1, is attached to a steam generating chamber 6 by means of a screw 12 having a bore 13 for the steam. An electric element 7 is secured between the sole-plate 11 and the chamber 6. Three radial grooves 22 extend from the recess 15 on the underside of the soleplate and the closure 16 is threaded into the recess 15. The closure has a flange which engages the depression 17 and overlaps the ends of the grooves 22 to guide steam into them from an annular recess 21 between the closure 16 and the recess 15 which communicates with the bore 13 through apertures 20. In a modification, Fig. 4, this closure 16a is a washer held to the screw 12a by a screw 24, steam reaching the grooves 22a from a bore 13a through a recess 25 and bore 20a in the screw 24. In a further modification, Fig. 5, the closure 16b may be a disc held in the depression 17b of the sole-plate by screws 26.

Title: Electrolytic process for making organolead compounds
IPC: C25B3/13
Filed: 1960-06-01
Abstract: 895,457. Making organo-lead compounds, electrolytically. ETHYL CORPORATION. June 1, 1960 [June 23, 1959], No. 19359/60. Class 41. Organo-lead compounds are made by electrolysing an organo-boron complex using a lead anode. Examples of the boron complex include sodium tetraethyl boron, potassium ethyl triphenyl boron, pyridinium tetraethyl boron, tetraethyl ammonium, tetraethyl boron, and derivatives, e.g. sodium triethyl boron cyanate or amide. At least one of the organic groups is an alkyl group preferably of 8 C atoms or less. Substituent groups which may be present in the anionic boron radical include hydroxy halogen, sulphate, nitrate, phosphate, arsonate and azide. These compounds are liquids or low melting solids, and are electrolysed in molten state below 120 C., or dissolved in solvents, e.g. propyl ether, glycol ethers, and poly-ethers, dioxane, amines, aromatic hydrocarbons, lactones, or water. An alkali metal or alkaline earth metal salt may be added as conductor and melting-point depressant. Voltage is preferably 10 v. or lower, and a low C.D. is applied. In examples, tetraethyl-, methyl-, or octyl-lead are made. The sodium metal or other metal in the complex is deposited at the cathode. The electrolyte may be regenerated by admitting hydrogen and the olefine required into the cathode region while passing the current, and this regeneration may proceed with the main reaction. A diaphragm cell is preferred.

Title: Improvements in or relating to sliding windows, shutters and the like
IPC: E05C17/62
Filed: 1931-07-07
Abstract: 376,010. Sliding window &c. holders. BECKETT, LAYCOCK, & WATKINSON, Ltd., Acton Lane, London, and CHAPPELLE, H., 7, Parkfield Crescent, Headstone Lane, Harrow, Middlesex. July 7, 1931, No. 19590. [Class 44.] In a sliding window holder having locking means releasable by a transverse shaft mounted on the window, the shaft is operable by a handle 22 encircling, or partly encircling, a non- circular part of the shaft. The invention is described as particularly applicable to the wedge fastening means described in Specification 365,327, with which rotation of the shaft in only one direction from its normal position is necessary. A bearing sleeve 17 has depending portions 18 forming a channel to receive the pane 19 with rubber or felt strips 20. The sleeve is gapped to allow engagement of the handle member with the shaft, which comprises three solid bearing portions 12, 13, 14 connected by tubular portions 15, 16 of smaller diameter, the portion 13 having grooves 25 to receive splines 24 on the handle member which is sufficiently wide to overlap the edges 26 of the gap in the sleeve. A spring 28 housed in a recess in the shaft serves to hold the shaft and handle in normal position. When raising the window by the handle 22, the portion 23 of the handle member abuts against the lefthand lip 18 and the shaft is not rotated, the wedge fastening members yielding automatically. When handle 22 is depressed to lower the window the shaft is first rotated so that cams 11 at the ends of the shaft release the fastening wedges.

Title: Improvements relating to the introduction of needle shanks into tongs for the purpose of grinding off the fins produced by stamping
IPC: B24B19/16
Filed: 1926-08-09
Abstract: 259,544. Schumag, Schumacher Metallwerke Akt.-Ges. fiir Prõzisionsmechanik. Oct. 10, 1925, [Convention date]. Breaking.-Needle shanks are introduced into tongs for grinding off the fin formed in stamping by placing the unbroken double shanks a on feed screws b which feed the shanks, with the fins resting on a knife-edged guide d to a position for breaking the shanks. In order to break the shanks, the screws are stopped and the shanks are lifted by notched plates f, the centre portions of the shanks bearing against an elastic jaw g until this bears against a sleeve h where they are held by an elastic jaw i. Continued upward movement of the plates f bends and breaks the shanks. The separated shanks are then moved to a horizontal position by plates k, and upon descent of the plates f, are gripped by jaws l, m which, after retraction of the jaws g, i, move longitudinally and rotate the shanks to bring the fins into the vertical plane, when they are grasped by tongs n and the fins ground off. For mechanical grinding the tongs have sliding jaws o, Fig. 5, instead of the jaws l, m, which turn the needles first through 90‹, and then for grinding the other side of the fin, through a further 180‹. With this form of tongs, the shanks may be gripped before breaking, the tongs being moved angularly relatively to one another to bend the shanks, which are afterwards broken where bent.

Abstract: 995,617. Moulding asbestos cement sheets. ATLAS STONE CO. Ltd. April 16, 1962 [May 31, 1961], No. 19685/61. Heading B5A. A moulding apparatus for forming asbestos cement sheets comprises a pick-up head 5, movable to pick up by suction and hold a sheet S in a flat condition from a table 1 and deposit it on a forming table 2 which includes a plurality of spaced forming bars 13 which can support part of the sheet and have apertures therein through which suction can be applied, the unsupported parts being allowed to droop, so that the sheet is partially formed, and a forming head 6 having forming bars 15 which correspond to those on the forming table, the forming head being movable into engagement with the forming table to complete formation of the sheet. Suction is then applied through apertures in the bars 15 and cut off in the bars 13, to lift the formed sheet. The forming bars 13 on the forming table are movable transversely of themselves so that the spacing may be reduced during moulding of the sheet. A pack table 3 is fed alternately with templates T from a template head 7 and sheets from the forming head 6. When a stack of sufficient size is formed on the pack table it is removed by conveyer or crane. The pick-up head, the forming head and the template head are supported on wheels which run in a gantry 12 so that the heads are movable together.
