Title: Improved manufacture of bearing metals
IPC: C22C13/02
Filed: 1924-01-18
Abstract: 210,428. Weissenstein, F. Jan. 23, 1923, [Convention date]. Alloys.-Bearing-metal alloys which comprise tin, antimony, and lead, within the limits of the field III of the accompanying diagram, with or without the addition of copper are improved by the addition of a small proportion of one or more metals such as mercury, bismuth, or cadmium, which form a solid solution with the principal metals of the alloy. In alloys containing 20-52 per cent of tin, 12-20 per cent of antimony, and 28-68 per cent of lead, with or without copper, 0.1-2 per cent of lead may be replaced by an equal amount of cadmium, or 0.1-3 per cent of lead may be replaced by an equal amount of bismuth, or of mercury, or of bismuth and cadmium.

Title: Improvements in or relating to the manufacture of artificial teeth
IPC: A61K6/083
Filed: 1921-01-12
Abstract: 218,846. Joannides, C. Jan. 12, 1921. Teeth, artificial.-In the manufacture of dental plates or other articles from dental rubbers of two different colours, e.g. white or pink rubbers for the teeth or gums and dark coloured base rubber for the palate, means are adopted to toughen the weaker (pink) rubber before it is subjected to the pressure of the stronger (base) rubber during vulcanization. The means employed are-(1) the use of pink rubber which has been previously partially vulcanized but is still plastic, (2) the use of partly vulcanized or unvulcanized pink rubber containing an accelerator with or without an activator such as zinc oxide so that it vulcanizes and toughens before the pressure of the base rubber is fully developed, (3) the use for the mould or part thereof of plaster containing an accelerator, or an activator, or a vulcanizing agent or any combination thereof so as to cause or accelerate partial or complete vulcanization of the rubber, (4) a preliminary partial vulcanization of the pink rubber by treatment with heat, chemicals, or gases after the application of the teeth but before applying the base rubber, (5) the use in conjunction with any of the foregoing means of strengthening ingredients such as fibre or vulcanized rubber incorporated with the pink rubber. In the manufacture of the improved pink rubbers the accelerator may be added during the usual mixing operation wherein heated rollers are employed, or may be added, together with part of the colouring or other ingredients, at a later stage after the rollers have cooled, or the rubber may be dissolved and the other ingredients, including the accelerator, may be incorporated in the solution which, after evaporation of the solvent, is formed into sheets. The rubber may be supplied in sheet form for packing by hand or by the injection process or in strip form as described in Specification 161,507. The partly vulcanized pink rubber containing an accelerator may be applied to the teeth and wax model before the flasking operation, as described in Specification 166,093, and will become further vulcanized during the boiling out of the wax. A thin sheet of the pink rubber may be applied to the wax model before nasking so as to cover the whole surface of the dental plate, thus giving a more natural appearance. The rubber employed may be replaced by equivalent vulcanizable substances such as synthetic rubber, balata, or gutta percha. The accelerators used may be organic or inorganic; those specified are-thiocarbanilide, hexamethylene tetramine, guanidine derivatives, Superac (a mixture of piperidine and clay) and Xylos. The use of soft rubber to cover the palate portion of a metal plate is referred to.

Title: Improvements in or relating to x-ray diffraction apparatus
IPC: G01N23/207
Filed: 1954-01-22
Abstract: 739,345. X-ray apparatus. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Jan. 22, 1954 [Jan. 26, 1953], No. 1968/54. Class 98 (1). An X-ray diffraction apparatus for determining the orientation of crystal lattice planes comprising a radiation detector and a D.C. measuring instrument connected thereto includes a device causing the crystal required to be tested to oscillate about the axis of the goniometer and reversing the direction of the current through the measuring instrument whenever the crystal is at a predetermined phase of its oscillation. As shown, a support 17 rotatable about a shaft 16 carries a holder 19 for a crystal 15. The holder is pivoted on shaft 16 for oscillation by means of a cam 21, driven by motor 32 and against which the holder is urged by a spring 20. A beam 11 of radiation from an X-ray tube 10, collimated as by a slit 12, is reflected by the crystal when the lattice planes are in the correct position, and the reflected beam 25 falls on a radiation detector 26, connected to a D.C. measuring instrument 28 through a reversing switch 30, also shown diagrammatically at 27. The switch is operated by a cam 31 on the same shaft as cam 21, the cams being preferably so adjusted that the switch is operated whenever the crystal passes through its mean position. When the support 17 is turned until the lattice planes of the crystal, in its mean position, are at the correct angle to the incident beam, there is a zero reading on instrument 28, which is more easily determined than a maximum reading. The angle of support 17 is indicated by index 39 on a scale 38. By calibration with a crystal of which the lattice planes make a known angle α with the crystal face, the angle α for any crystal can be read directly from scale 38. An easier determination of the zero point is obtained by using a collimator in the primary beam which allows more radiation to pass in the plane of the goniometer axis than in the marginal zone. Such a collimator may comprise a diaphragm with an aperture of greater height in the centre than at the edges, or with attenuating filters at the edges.
