Abstract: 798,082. Drawing. IMPERIAL CHEMICAL INDUSTRIES, Ltd., HANDS, S., and FREUND, A. O. F. Dec. 1, 1954 [Oct. 9, 1953], No. 34771/54. Divided out of 798,081. Class 83( 4). [Also in Group XXXVI] In drawing titanium or titanium base alloy rod, &c., the material to be drawn is provided with an adherent electrodeposited coating of silver or silver base alloy to form a lubricantretaining layer. The thickness of the silver coating, which may be stripped on completion of the drawing operations, must not be reduced below 0.0005 inch during drawing and to ensure this the partly drawn material is, if necessary, replated at a convenient intermediate stage. As an example, a 0.5 inch diameter descaled titanium rod, after treatment in boiling hydrochloric acid, was plated with a silver coating 0.005 inch in thickness and cold drawn in a series of 10 per cent drafts with an anneal in air at 700‹ C. every third die until diameter of 0.165 inch was reached. The material was then cleaned in trichlorethylene vapour, cathodically degreased, given a slight anodic etch in a mixture of sodium cyanide and caustic soda and replated with 0.005 of silver. Drawing was then continued with regular annealing as before, the final thickness of the wire being 0.018 inch.

Abstract: 1321499 Respiratory appliances DAMECA AS 26 July 1971 [27 July 1970] 35011/71 Heading A5T [Also in Division F2] A valve 2 for use with a closed anaesthetic plant has a plate closure member 19 disposed between two seats 26, 27 and carried by a spindle 18 guided by ribs 20, 22. A spiral spring (40), not shown, is disposed between the plate and the ribs 22 and an elastic stop in the form of an elastic body or a spring- loaded member 33 is carried by a housing top part 11 which is screw-threaded on a lower part (10) mounted on an anaesthetic gas flow pipe 13 and communicating with an outlet pipe (12). In use the valve 2 is disposed in a plant having an anaesthetic gas inlet 9, check valves 1, 4, rubber bag 3, breathing mask 6 and CO 2  absorber 8. With the elastic stop in the position shown above the highest point of travel of the spindle 18 the plate with normally abut seat 26. Over pressure in pipe 13 will move it off seat 26 to allow anaesthetic gas to flow to outlet pipe 12 but when bag 3 is squeezed the plate 19 will abut seat 27. When the top housing part 11 is screwed down so that the spring-loaded member 33 abuts the spindle when the plate abuts seat 26 the valve acts as a safety valve. The housing part 11 may be turned to an intermediate position wherein the spindle abuts the member 33 when the plate is between seats 26, 27. This position is used when anaesthesia is to end and only oxygen is supplied, expiration of the patient causing the plate to move off seat 26 to an intermediate position. Outlet pipe 12 may be connected to a pressure equalising bag and a vacuum unit and may have a gas oscillation clamping finger-stall or diaphragm mounted over a side opening and covered by a transparent dome.

Convention date, Nov. 20, 1929. [Class 103 (i).] In an internal-expanding double-shoe brake the shoes 10, 11 are expanded by a floating wedge 46 acting on rollers 51 on the ends of the shoes, and the other ends of the shoes are pivoted at 14 to pins 12 slidable in a housing 18 in which the pins are loosely mounted to permit radial movement of the pivoted ends of the shoes towards the brake drum 54 when the brake is applied. The pins have chisel-ends 16 engaging a serrated conical member 17 having a screwed shank 25 which may be rotated to compensate for wear of the shoes. A washer 29, Fig. 4, is riveted to the pointed end of the member 17 and slides in a sleeve 28 in the housing 18 to form a dust-shield and a sleeve 23 is contracted on the shank of the cone for the same purpose. The wedge 46 is connected by a rod 36, passing through a king bolt on the front axle of the vehicle, with an operating- cam 44 on a shaft connected with the brake pedals or levers. A central web 52, Fig. 6, of the wedge extends between the rollers 51 and lateral movement of the wedge and of the shoes is prevented by fixed washers 47 mounted on a stud 48 on the anchor plate 19, the washers 47 acting as a stop for the shoes in their inoperative position.

Abstract: 1313308 Making apertured strip; girders; expanding metal; bending; shearing W W BUTLER 21 July 1970 [28 July 1969] 35167/70 Headings B3A B3E and B3W [Also in Division B5] A method of making an apertured strip, which may be a metal or a ductile plastics strip, comprises slitting the strip along a line, parallel to and near one longitudinal edge and pushing the portion of strip between the edge and the slit out of the plane of the strip to open the slit in a plane normal to that of the strip. The portion of strip can then be deformed in a direction parallel to the plane of the strip and away from the original slit line and pressed back into the plane of the strip to leave apertures 30, Fig. 10, adjacent the strip edge. The strip may have one longitudinal edge or both apertured and may be used flat or bent into an angle as shown in Fig. 10. The process is carried out by means of a die 18 which engages part of the edge of the strip and shears and bends the portion 17, Fig. 3, the rest of the strip being supported by a block 20. A plurality of dies 18 may engage one edge or two dies 18a, 18b may be used, one on each side of the strip, Fig. 16, to slit and deform portions 17 on both edges of the strip simultaneously. The die 45 shown in Fig. 16 is designed to carry out the deforming out of and back into the plane of the strip simultaneously as a strip 10 is fed through it. The portions 51 and (50), Fig. 19 (not shown), deform the portions 17 outwardly of the strip in a die section 46b and 47b and a final section 46c, 47c flattens the portions 17 back into the plane of the strip. Alternatively the deforming of the portions back into the plane of the strip may be performed by moving a roller 32, Fig. 6, from the middle of the strip to its edge to roll out the deformed portion 17. The roller may be rolled in a direction normal to the strip edge to produce symmetric apertures or obliquely to produce asymmetric apertures.

Abstract: 522,033. High-molecular ketenes. DEUTSCHE HYDRIERWERKE AKT.-GES. Dec. 2, 1938, No. 35210. Convention date, Dec. 2, 1937. [Class 2 (iii)] High molecular ketenes are prepared by treating halides of aliphatic or cycloaliphatic monobasic carboxylic acids having at least six carbon atoms in the molecule with strong tertiary bases, at ordinary or raised temperatures and in the presence or' absence of a water-free indifferent solvent such as carbon disulphide or benzene. As starting materials there are specified the halides, especially the chlorides of caproic, lauric, palmitic, oleic, montanic and the naphthenic acids, and specified bases are the trialkylamines such as trimethylamine, triethylamine, tripropylamine, alkylated ethylenediamines and alkylpiperidines. The ketenes are acylating agents for organic compounds which contain an active hydrogen atom such as amines, hydroyl compounds and their substitution products, e.g. #-oxyethanesulphonic acid, #-methylaminoethane sulphonic acid. In examples triethylamine is gradually added to lauric acid chloride or palmitic acid chloride dissolved in carbon disulphide with the exclusion of atmospheric moisture, and left to stand for 24 hours; triethylamine hydrochloride is filtered off and the filtrate is evaporated to give decyl or tetradecyl ketene; decyl ketene forms potassium laurate on boiling with alcoholic caustic potash. The Specification as open to inspection under Sect. 91 includes, in addition, as starting materials the halides, especially the chlorides, of aliphatic or cycloaliphatic polybasic carboxylic acids, e.g. adipic acid, sebasic acid, cyclo-hexane-1, 2-diacetic acid, and of nuclear alkylated aryl fatty acids containing at least one aryl group. The hydrocarbon residues of the polybasic aliphatic or cycloaliphatic carboxylic acids as well as of the corresponding monobasic acids may also contain hetero-atoms, e.g. oxygen or sulphur, or groups containing hetero-atoms, e.g. hydroxyl, ester, mercaptan or sulphone groups. This subject-matter does not appear in the Specification as accepted.
