Title: Device for taking up excess play between two members
IPC: F16D65/54
Filed: 1955-04-15
Abstract: 768,775. Internal shoe-drum brakes. FLUELER, J. April 15, 1955, No. 10925/55. Class 103 (1). [Also in Group XXIV] A one-way locking device 1, 4, Fig. 1, for taking up excess play in linkwork is applied to vehicle braking mechanism to compensate for wear therein. As shown in Fig. 3, brake shoes 11, 12 are expanded against a spring 17 either by a hydraulic piston 13 or by a hand-brake cable 14 actuating a lever 15 pivoted at 15<SP>1</SP> to the shoe 12. A threaded or ridged rod 4 pivoted to the lever 15 passes through a hole in a spring-loaded member 1 pivoted to the shoe 11, the hole having upper and lower staggered toothings 2, 3, Fig. 1, which in the " brake off position shown lock the rod 4 against movement to the right and thus determine the rest position of the shoes. A spring 16 holds the lever 15 against the shoe 12 so that each time the brake is applied by the piston 13 the member 1 is canted to the dotted line position wherein only the lower toothing 3 stays in mesh with the rod 4. If, due to wear in the brake linings, the brake-applying movement is excessive, the rod 4 ratchets over one or more of the teeth 3 so that the shoes subsequently return to a new " brake off position closer to the drum 10 to compensate for the wear. In a modification the hand-brake mechanism is omitted and the members 1, 4 are directly pivoted to the two shoes. In a further modification two shoes are actuated by two pistons against two return springs, and the rest position of the shoes is determined by two locking devices 1, 4 mounted on a fixed support. In a mechanical brake for vehicles movable only in the forward direction, articulated brake shoes are expanded by a lever-actuated eccentric 19, Fig. 6, connected to one shoe through a locking device 20, 21. A second locking device 22, 23 takes up excess play between the shoes and the brake drum, while the device 20, 21 compensates for wear, e.g. in the return stop of the brake pedal: In a modification for vehicles movable in both directions the second brake shoe is actuated by a cam movable with the eccentric. The bearing for the eccentric shaft is adjustable to adjust the cam position.

Abstract: 696.318. Indicator lamps. SMITH & SONS (ENGLAND), Ltd., S. April 18, 1952 [May 9, 1951], No. 10957/51. Classes 75(ii) and 75(iv) A light indicator comprises a light source 12 and a light transmitting cylinder 6 having one end 7 protruding from the lamp housing 1, the cylinder being revolvable about its axis and having at its inner end an internal reflecting surface 8 which is inclined to the axis of the cylinder andwhich, in one position of the cylinder reflects a maximum amount of light along the cylinder and through the protruding end, and rotation of the cylinder from this position diminishes the amount of light so transmitted. The source 12 and the cylinder 6 are mounted in separate cylindrical. bores 3, 2 in the moulded plastic lamp housing 1 and a passageway 4 carrying a coloured film 5 is formed between the bores for the passage of light. The cylinder is surrounded by a metal sheath 9 having an opening 18 located opposite the. reflecting surface 8. As the cylinder is rotated and the amount of light reflected through the end of the cylinder diminishes the amount of light received by the reflecting surface is also progressively reducedby the sheath. The reflecting surface 8 is preferably a plane surface at 45 degrees to the axis of the cylinder and it is coatedexternally with white pigment. The protruding end of the cylinder is convex and is sand blasted. The rotation of the cylinder is limited to 180 degrees by a flange 10 of 180 degrees extent and a stop 11. Access to the light source is provided by a screw cap 15 closing the bore 3.

Abstract: 1,183,354. Moulding refractory bricks from particulate material. RHEINISCHE KALKSTEINWERKE G.m.b.H. 8 March, 1967 [12 March, 1966], No. 10983/67. Heading B5A. Variations in weight and volume of wedge shaped refractory bricks moulded from granular material, e.g. burnt dolomite and tar for lining of furnaces and converters, are minimized by pre-compressing with a ram 4 a predetermined volume of the material fed to a die 3 from a slide 2, and thereafter depositing further material in the die 3 which is then displaced for compression by an inclined surface ram 7, whereby the further volume increases with the compressibility of the material during the precompression, and/or a decrease in the weight of the first volume as measured by a device 10 acting through a regulator 8 which acts to displace a lower mould plunger 9 and may also act to decrease the pressure of ram 4 with a higher weight of the predetermined volume. The pressure of the ram 7 may also be increased with increasing compressibility of the material as measured by a device 5. The ram 4 is provided with a surface of adjustable inclination whereby it may press the material to an angle opposed or intermediate that produced by the ram 7. The mould table may reciprocate, or rotate. The surface of ram 4 may be provided with spikes whereby the surface of the compressed material is roughened by a shaking motion to assist bonding of the further volume.

[Classes 1 (i) and 32] A continuous process for the catalytic cracking or conversion of hydrocarbons consists in circulating catalyst particles through a conversion zone 3 through which hydrocarbon vapours are passed, and then through a regeneration zone 1 through which the catalyst passes in a substantially solid column of particles and which contains conduits 14 through which a heat exchange medium is circulated to control the temperature. The conversion zone may also be provided with heat exchange conduits. To facilitate the passage of gas through the catalyst, the regenerator may contain angle-iron baffles 48 provided with gas passages 50 which are covered by the next higher layer of baffles, the passages from the highest layer being carried up above the level of the catalyst mass and bent over to exclude falling catalyst.

Abstract: 527,720. Hydrocarbons. TEXACO DEVELOPMENT CORPORATION. April 13, 1939, No. 11209. Convention date, April 21, 1938. Drawings to Specification. [Class 2 (iii)] In a process for the alkylation of isoparaffins with olefines in the presence of a sulphuric acid catalyst of the type described in Specifications 479,345 and 515,367, a part of the total reaction mixture is recycled so as to maintain a greater ratio of acid and isoparaffin to olefine than is present in the initial feed. The initial hydrocarbon such as a C4 fraction may be subjected first to a selective polymerization treatment to produce C8 hydrocarbons, the resulting mixture being then alkylated with isobutane to yield a mixture including iso-octanes ; or the C8 olefines may be first separated and then alkylated ; and the higher boiling constituents, including C12 hydrocarbons, may also be separately alkylated. In the polymerization operation isobutylene may be polymerized to 2-2-4 trimethyl pentene or isobutylene may be combined with butene-1 or butene-2 to form mixed polymers; the production of these mixed polymers, which is desirable, may be promoted by recycling unreacted normal butenes to the polymerization operation. The polymerization may be effected by phosphoric or diluted sulphuric acid ; phosphoric acid is preferably used in kieselguhr and sulphuric acid as liquid of 60-70 per cent., which at 160-180‹F. will condense isobutylene with normal butenes to produce iso-octenes. The ratio of isobutane to olefine in the alkylation step should be at least 1:1 and is preferably 3-5:1. The polymerization step may be effected at 300-350‹F. and 550 1b. pressure, and the alkylation at 25-150 lbs. pressure or higher. When the alkylation acid is too much reduced in strength to be useful for that operation it may be diluted for use in the polymerization step. An example describes the treatment of a C4 mixture containing isobutylene, normal butylenes and iso- and normal butanes. The Specification as open to inspection under Sect. 91 includes three examples in which there is no re-cycling in the alkylation process. This subject-matter does not appear in the Specification as accepted.
