Title: Improvements in hinges
IPC: E05D11/06
Filed: 1919-03-14
Abstract: 143,662. Cheston, A. S. March 14, 1919. Hinges.-A concealed stop-hinge for motorvehicle and like doors, of the type comprising a tongue member carried by the door, engaging and pivoted within a housing let into the door frame, has the curved tongue member 1, Fig. 2, formed integral with attachment plates 4 rigidly secured to the door. The tongue-pieces are pivoted at 3 between a housing-member 2 formed by bending a strip of metal into narrow U-shape, the ends being turned out to provide attachment plates 5 screwed to the door pillar. The tongue carries a laterally projecting stud or pin 6 which engages and moves in a quadrant-shaped slot 7 having closed ends in one side of the housing, the ends of the slot limiting the movement of the door. In a modification, Fig. 7, the ends of the plates 1 forming the tongue are bent up at right-angles to form the projecting stud, and the slot in the housing member is open at one end.

Title: Improvements in or relating to cast molybdenum base alloys
IPC: C22C27/04
Filed: 1952-03-12
Abstract: Cast Mo alloys, particularly for parts of turbo-jets, rockets, piercing points for making seamless steel tubes, electrodes for heating molten glass and dies for casting brass consist of at least 70 per cent Mo or at least 70 per cent Mo and W, with the proportion of Mo exceeding that of W, and V 0.25-7 per cent or Ta 0.5-9 per cent. or Nb 0.25-10 per cent.  The alloy may also contain: Ni up to 0.4 per cent; Fe up to 13 per cent; Co up to 0.9 per cent; Cr up to 2 per cent; Th 0.01-0.5 per cent.  Be up to 0.25 per cent and/or Al up to 2.5 per cent may be present in the alloy but the maximum amount of Be, in excess of 0.03 per cent, and Al, in excess of 0.4 per cent must be reduced within the range stated as the amount of each alloying transition element and W approaches its upper limit.  Up to 0.05 per cent O is permissible in the alloy providing Be and/or Al is added in amounts sufficient p  to react with all the O present.  C up to 0.25 per cent may be present in the alloy but preferably should not exceed 0.07 per cent.  The alloys may be made by mixing Mo with or without W, transition element and the other elements, if used, in the form of powders, pressing into pellets, sintering the pellets together in the form of a rod, arc melting the rod as a consumable electrode in vacuo or in an inert gas atmosphere in a closed chamber and collecting the metal in a water-cooled copper mould. Specifications 27710/10, [Class 82(i)], 652,491, [Group XXII], 656,796, 734,413, [Group XXX], 741,359 and 741,360 also are referred to.
Patent GB-621942-A (GB)
Title: An improved method of carbonization and activation of granulated or pulverulent carbonaceous materials
IPC: C01B32/336
Filed: 1947-03-07
Abstract: <PICT:0621942/III/1> In the preparation of activated carbon, granulated or pulverized carbonaceous material is admitted to the uppermost of a series of finely-perforated horizontal plates, each of the plates being traversed by the material before it descends to the next lower plate, and a hot gas is passed upwardly through the plates, whereby carbonization of the material is effected at the upper level and activation is effected, at a higher temperature, at the lower level.  As shown, the charging hopper 10 feeds the top plate 6 of three finely-perforated refractory plates 4, 5, 6, and is distributed by a rotary rake 7.  The overflow of material passes down a central pipe-section 12 to the next plate 5 and then outwardly to the annular conduit 13 for delivery to the plate 4, and finally to the central discharge pipe 15.  The gaseous products of the heat treatment are passed to a condenser 17, the liquid condensate being tapped off at 18.  The combustible gases from the condenser 17 are drawn off by a vapour-jet injector 19 and burnt, with air admitted at 21, in the chamber 2.  The treatment of sawdust is described, the combustion being so regulated that a reducing atmosphere is maintained in the oven and the temperature of the mixture of steam and combustion products reaches a temperature of 800-900 DEG  C.  The carbonizing temperature at the plate 6 is 500-600 DEG  C.  The gas may be reheated between each perforated plate, either electrically or by burning a part of the gas, derived from the sawdust, by introducing secondary air between the plates.  The treatment of dried peat, shells of groundnuts, fruit kernels, charcoal peat or lignite dust is referred to.

Title: Improvements in the deresinification of waxes containing alcohols of high molecular weight or of alcohols obtained therefrom
IPC: C11B11/00
Filed: 1930-03-03
Abstract: Natural waxes or their alcoholic constituents or mixtures of both, are freed from resins by treating them at room temperature with two or more organic solvents, one (a) of which dissolves the waxes homogeneously and another (b) dissolves them dispersely, the former type of solvent (a) being used in an amount insufficient to completely dissolve the wax.  The solvents (a) comprise hydrocarbons such as benzene or benzine, or tetrahydronapthalene, and form clear solutions of waxes.  The solvents (b) comprise alcohols, ethers, esters or ketones, form turbid solutions of waxes, and suppress the solvent power of solvents (a).  Crude montan wax is pulverized, in a percussion mill, and after passing through a sieve, the uniform powder is treated at room temperature with benzine to form a pasty mass. This is then stirred with cold alcohol, and after settling the supernatant alcoholic solution of resin is decanted, and the residue is washed with a mixture of alcohol and benzine.  The purified wax is fused to remove final traces of solvent.  The alcoholic extract is distilled to recover the resin therefrom. The step of pulverizing the wax may be replaced by dissolving the wax in warm benzine, and cooling to precipitate the wax as a pasty mass.  Prior to de-resinification the waxes may be de-acidified by treatment with alkali, the resulting soaps being removed in the subsequent extraction with alcohol.

Title: Improvements in or relating to spraying apparatus
IPC: B05B1/18
Filed: 1923-03-10
Abstract: 217,297. Lilly, J. March 10, 1923. Rotary disc valves; actuating mechanism.- A spraying nozzle for a syringe, Fig. 2, comprises a diaphragm 3 fixed in the front end of the syringe casing and a valve-member 13 associated therewith, controlling the fluid supply to a pair of passages 9, 10. One passage 9 leads to a jet nozzle formed in a screwed spigot 6 concentric with the diaphragm, and the passage 10 to the space 5 between a rose-member 4, screwing over the spigot 6, and the diaphragm 3. The apparatus may, therefore, by holding it in desired position indicated by a projecting lip 16, be used to give either a spray or single jet, according to whether the ball-valve 13 closes the passage 9 or the passage 10, respectively. The ball 13 rolls in a cone-shaped cage 11 formed separately from the diaphragm 3 to facilitate fixing it accurately in position relative to the seatings formed in the diaphragm, and is prevented from leaving the cage by a cross-bar 12. The spigot 6 may be arranged to project the jet at an angle to the axis. particularly when the apparatus is intended for use in cleaning motor cars, or a smaller spray nozzle may be substituted for the jet. Fig. 4 illustrates a modified form adapted for attachment to a hose. The diaphragm 45 is formed in a hose attachment-membed 27 and, by turning the nozzle members 17, 18 relatively to the diaphragm, the passage 32 in the diaphragm may be placed in communication with a passage 23 leading to the jet nozzle 24, or with a passage leading to the space 26 between the nozzle members 17 and 18, when a spray is required, or the supply may be cut off when the passage 32 is out of alignment with either of these passages. An indicator 43 is provided as before to show the position of the valve. The diaphragm is rotatably mounted upon a shank 36 attached to the nozzle member 17. a washer 29, prevented from rotation relatively to the diaphragm, being mounted between them. The bearing surfaces of the valve which may be conical instead of flat as shown, are pressed together by a spring 37 mounted on the shank 36.
