Title: Improvements relating to the filling of expansion-and-contraction joints
Inventor: ROBIN PETER HUTCHINSON
IPC: E01C11/10
Filed: 1956-06-23
Abstract: 855,069. Expansion joints for concrete. SEMTEX Ltd. April 11, 1957 [June 23, 1956], No. 19513/56. Class 20(4) Joints in concrete slabs for floors, airfield runways, roads &c., are filled by introducing into the joint a strip comprising two or more thicknesses of resilient cellular material joined at one longitudinal edge with this edge leading, the strip having a width in the uncompressed state greater than the width of the joint and having substantially flat joint-wall-contacting faces. The strip is inserted by placing a thin rigid plate midway between the thicknesses of the strip and forcing it down into the joint after which the plate is removed; alternatively, rigid rectangular, trapezium-shaped or triangular frameworks of steel &c. may be used. The strip may be of natural or synthetic rubber or a synthetic resin including expanded vinyl resin compositions, particularly plasticized polyvinyl chloride or plasticized vinyl-chloride/vinylidene-chloride copolymer or vinyl-chloride/vinyl-acetate copolymer, plasticized if necessary. Synthetic rubber compositions particularly including those which are resilient to swelling by paraffinic oils e.g. butadiene-acrylonitrile copolymers, copolymers of butadiene and methyl isopropenyl ketone and neoprenes may be used and also copolymers of isobutylene with butadiene and isoprene. An adhesive may be provided between the joint and the filling strip. In an alternative method of introducing the strip into the joint, the strip is compressed to a thickness less than the joint width and stitched in the compressed state after which it may be inserted without the use of a tool. The stiches may then be cut so that the strip presses against the walls of the joint; alternatively, the stitching thread used may be of a material which will dissolve or relax on application of a solvent into the joint, the material of the strip being unaffected, e.g. the thread may be of rayon and the solvent may be methylene dichloride or methyl ethyl ketone and may form part of the adhesive if used.

Title: Improvements in or relating to shock absorbers for vehicles
IPC: F16F7/06
Filed: 1925-08-12
Abstract: 258,404. Wilmart, P. Aug. 12, 1925. Vibration - dampers. - A friction shock-absorber for spring-suspended vehicles comprises a hollow cylindrical casing a integral with a base plate l and containing a spiral spring h of which one end is secured to the fixed casing and the other inserted in one of a series of notches v in the hub of a lever. g mounted on an axis eccentric to the casing. A friction belt e has one end secured to a pin i on the lever g, passes partially around the outer circumference of the casing, and has its other end secured to the axle of the vehicle. A finger y on the lever g extends over a spring z pressing on the belt e, so that when the vehicle springs are compressed the rotary movement permitted to the lever causes the finger y to approach the casing, due to the eccentricity of the lever axis, and press the spring z harder on to the belt, the pin i also approaching the casing. The friction of the belt on the casing is thus greatest when rebound is about to commence.

Title: Process for the manufacture of arsenates from arsenious acid or arsenites
IPC: C01G28/02
Filed: 1934-07-12
Abstract: Alkali arsenates, or mixtures thereof with alkali arsenites, are obtained by subjecting an aqueous solution containing arsenic trioxide and alkali to oxidation by intimate contact with air or a gas containing free oxygen under normal pressure in a fine state of division or over a large surface area.  Preferably the proportions of alkali and arsenic trioxide are such as correspond to trialkali arsenate, elevated temperatures, say 80--100 DEG  C., are used, and oxidation is effected in presence of a catalyst such as a noble metal, a metal having variable valency, or compounds or mixtures thereof.  The specified catalyst is copper sulphate.  In carrying out the process, the oxidizing gas may be supplied from a fine aeration device such as is used in the yeast industry, or the solution may flow down a tower filled with bodies of large surface area up which the gas is passed.  In the latter case, the process may be a continuous one, a part of the treated solution being recirculated, and a part being treated with milk of lime to recover calcium arsenate and reform alkali which is used for dissolving more arsenic trioxide for continuing the process.  From the calcium arsenate, by treatment with sulphuric acid, a solution of arsenic acid may be obtained.
