Abstract: 1,183,643. Abrasive tool. WELLSON ABRASIVE PRODUCTS. 30 July, 1968 [13 Nov., 1967], No. 51573/67. Heading B3D. A surface-cleaning hand-tool, e.g. for cleaning electric contacts and like components in electric circuits, comprises a supporting rod or handle and a rigid, abrasive-coated blade, substantially thinner and shorter than the rod or handle, secured at its edge to the end of the rod or handle. The rod or handle is preferably formed of, or protected by a covering of, electrically non- conductive material. The blade may be separately pre-formed, e.g. from metal strip, provided with its abrasive surface, e.g. by anchoring an abrasive deposit to the blade by a nickel deposit, and attached to the rod or handle, which may be of plastics and moulded to the blade. A blade 1 of thin, high-carbon spring steel strip coated on one or both sides with abrasive, e.g. diamond powder, is mounted at one end of a handle 2. The blade may have a tang provided with holes 4 and/or teeth or lugs 5 to ensure firmer anchorage in the handle. The rear end of the handle may have side ribs or wings 6 to facilitate a firm, non-slip grip by a user, also assisted by a rectangular cross-section of the handle. In making the tool, the blade is surfacecleaned and areas on which an abrasive coating is not to be provided are coated with masking paint. The blade is anodically immersed in sulphuric acid and current passed. The blade is then washed in cold running water and transferred to a bath of nickel sulphamate solution, and current passed. Abrasive powder is sprinkled on to the blade surface or surfaces and plating resumed or continued for a period after which surplus abrasive is removed. Plating is continued to ensure secure anchorage of the grains. The blade is cleaned, masking material removed and polishing carried out with a mop. The blade may be "flashed" in a bright nickel solution. Finally the handle is moulded in firm connection with the blade.

[Also in Division B2] A shoe lasting machine includes an applicator 100 for applying adhesive to the margins of an insole 3, the applicator having open channels 11 on its top surface which is pressed against the insole and through which an adhesive flows. The last 2 carrying the insole 3 is supported by a shoe support 1 on a hollow rod 105 which can be moved heightwise by a piston 110 in cylinder 103. A bracket 20, which carries the applicator 100, is slidably mounted on the rod 105 and is urged upwardly to press the applicator 100 against the insole 3 by a spring 119. The applicator can be moved away from the insole 3 to allow the wipers (6) to perform their wiping action by means of a piston and cylinder 126, 104, the piston rod 125 of which passes through the hollow rod 105 and is connected to the bracket 20 by a pin 113 which passes through slots (not shown) in the hollow rod. The applicator 100 consists of a base 8 which is adjustably connected to the bracket 20 by bolts 17 and an upper part 7 whose upper surface conforms to the contours of the last bottom and has channels 11 formed therein. Adhesive is supplied to the channels 11 from a singlestroke injection pump (not shown) via a flexible hose and supply ducts 24, 25 to the toe portion of the applicator where it flows along left and right channels (11a and 11b) and any surplus adhesive is returned to the pump via drainage ducts 12, 14 and flexible hose 15. The channels 11 gradually reduce in thickness and are formed with a restriction 11<SP>1</SP> at their drainage ends so that the pressure of the adhesive is increased. The base 8 is heated by electrical heaters 26 to maintain the adhesive in molten condition and top part 7 is connected to the base by tubular members 9, 10 so that one top part 7 may be replaced by another of a different size or shape.

Each jet nozzle 58 is mounted on a block 56 and is supplied with quenching fluid through passage 70 flexible conduit 42 and a ring header 34 mounted on the support. The jet block 56 is mounted on slide rods 72 and is biased towards article 74 by a pair of coil springs 76. Wheel 60 on the jet block contacts the article as it moves and, with the biasing action of the springs, ensures that the jet is maintained at a constant distance from the article during quenching. Rods 72 and springs 76 are in turn mounted on slide component 54 which, by means of draw bolt 80 and guide bolt 82, can be adjusted and clamped at a desired position radially on the support. For quenching larger diameter articles all of the surrounding jets may be in operation to form a continuous fluid curtain around the article. For smaller diameter articles, certain of the jet structures may be withdrawn radially and made inoperative as shown in Fig.3 to allow the remainder to be at the desired distance from the article. Jet spoons 68 are provided to control the angle of the jet and to ensure that  they form a continuous quenching curtain. The quenching apparatus may include a plurality of such supports, with their associated jet structures, disposed along the longitudinal axis of the article Fig. 1 (not shown).

A cylindrical connector 18 is rotatably connected to a swivel neck flange 20 which is held against the incision in the neck of the patient by straps (24) in slits (22). An obturator 48 with a blunt end 50 fits within the cannula for locating the tracheal tube within the trachea, whereupon the obturator is removed and replaced by an inner cannula (26), Fig. 3, (not shown) comprising an axially tapered connector (28) constructed to mate with the connector 18. The outer and inner cannula and membrane are constructed of a non toxic polymer, preferably the same one, whereby the outer cannula and membrane are formed integrally. Polyvinyl chloride may be used, and barium sulphate may be added to permit X ray observation.
