Title: Improvements in and relating to pit props
IPC: E21D15/00
Filed: 1949-04-21
Abstract: 677,899. Pit props. DOLLERY & PALMER (PNEUMATIC TOOLS), Ltd. (Soc. d'Etudes et de Recherches Industrielles et Minieres, S.E.R.I.M.). April 21, 1949, No. 10580/49. Addition to 670,004. Class 20(ii). Consists in an improvement in the invention of the parent Specification, which describes a telescopic pit prop in which a longitudinally slotted tube 8 is slidable lengthwise relatively to a tube 1 and the parts are clamped in position by jaws 7, carried by a support 3 on the tube 1 and forced by a transverse key 4 and a wedge 5 against the inside wall of the tube 8. The transverse key 4 bears against slots in an abutment sleeve 9 fixed to the part 1. The improvement comprises formations of the key 4, so that it will deform before buckling of the prop occurs. The key 4 has a retaining head 18 with an inclined face 18a, adapted to bear against the lefthand slot (as seen in the Figs.) of the sleeve 9 when the key is inserted, so that the key is forced downwards and the jaws 7 apart against a spring hoop 17 to apply a preliminary pressure. A ring 19 is clamped round the part 8 to prevent it buckling, by a bolt 20 which passes through a distance piece (not shown) which fits inside the tube 8. The tube 1 may continue upwards beyond the member 3 and have slots in its wall for the wedge 4, the tube 8 then being inside it. The prop may be in sections clamped together by bolts 24, 25 (Fig. 8). The upper part 8 may thus be shut, and may be of light metal, and manufactured by extrusion in a complicated cross-section, e.g. one having wedge grooves. The sleeve 9 may also be of light metal, in which case steel linings 27 are desirable to minimise friction. Conversely, if it is desired to increase friction the upper prop half may have an anticorrosive coating.

Title: Improved machine for making clothes pegs
IPC: B23B13/02
Filed: 1920-04-16
Abstract: 164,919. Jones, M. April 16, 1920. Lathes; chucks.-In a machine for making clothes pegs &c. a wooden rod 33 is fed intermittently by dogs 29 and is rotated in the intervals between the feed movements while a cutter 63 shapes the head of a peg and a circular saw 82 simultaneously severs the previously shaped peg from the rod, and the severed pegs are held by a gripper 93 while a circular saw 107 gullets them and cutters 108 form the flared mouths. The feed-dogs 29 are pivoted to a collar 22 having a limited sliding movement on an inner tube 32 through which the wood is fed, and the collar is reciprocated by a lever 14 from a cam 7. Another collar 19 has a limited sliding movement, which is adjustable by set-screws, on the collar 22 and is linked to the dogs so as to cause them alternately to grip and release the wood to feed it. One end of an intermediate tube 34 is split at 36 and is of conical shape to correspond with the coned end of an outer tube 38 which is rotated by a pulley 45. When the wood is freed by the grippers 29 a cone 49 is moved along the tube 38 by a lever 57 and rocks levers 48 which force the above-mentioned conical parts into contact and cause the tube 34 to be rotated and to grip the wood so that this rotates with it. The shaping-cutter 63 and the saw 82 are then actuated by a lever 76, the cutter being shaped as shown in Figs. 8 and 9 so that the cut proceeds gradually from the wider to the narrower parts of the peg. Discs 112 outside the gulleting and shaping cutters 107, 108 embrace the pegs to keep the cutters central. The clamp 93 and the gulleting-cutters are operated respectively by levers 94, 99.

Abstract: 1,140,896. Vitreous granules; removing oil pollution; ceramic compositions. WASAGCHEMIE A.-G. 11 March, 1966 [8 April, 1965; 16 Oct., 1965; 6 Dec., 1965], No. 10911/66. Headings C1C, C1J and C1M. [Also in Divisions B3 and C3] A granular material is formed by (a) forming a solution of 0.02-0À7 parts by weight of fibrous siliceous material in one part by weight of an aqueous alkali silicate, (b) removing water until a solid mass is formed and granulating, (c) providing the granules with a surface layer consisting of a high-melting oxide or substance capable of forming a high-melting oxide on heating, and (d) heating to 600‹-1000‹ C. The fibrous material may be glass, rock, or basalt wool. Porosity-increasing additives, e.g. sugar, glycerin, sulphides, oxides, hydroxides, or carbonates, or pigments may be included in the initial mixture. The surface layer may be provided by contact with an aqueous suspension of lime, chalk, zinc oxide, alumina, or iron oxide. The material may be moulded after addition of a binder, e.g. polyester or epoxy resin, gypsum, Portland or other cement, or lime, dry or moist oxidic masses, e.g. raw brick, fire clay, or tiling materials, or clay, kieselguhr, kaolin, clay mixed with TiO 2 , felspar, quartz or masses containing magnesite or corundum, e.g. 5-90% by weight based on the granular product. When ceramic masses containing the granular material are fired, cavities are formed where the granules were present, the cavities being enclosed by a thin skin of vitreous material. The granules may be coated or cast with a molten metal e.g. Al. The porous material may be present as partial or zoned layers-thus a tile may have a compact ceramic surface layer backed by a porous ceramic layer. After treatment with a hydrophobing agent, e.g. a metal soap or a silicone oil, the granular particles may be floated on water which carries a film of oil; they absorb the oil and continue to float, and may be easily removed, leaving the water oil-free.
