Title: Improvements in or relating to artificial dentures
IPC: A61C13/00
Filed: 1933-11-04
Abstract: Dentures are made by applying to the denture base a thin layer of material which is solid at the temperature of the mouth but is plastic at temperatures of 45 to 70 DEG  C., so that, after heating, the denture may be pressed against the jaw so as to be moulded accurately thereto.  Suitable materials are balata or mixtures of balata with small quantities of guttapercha, caoutchouc or both. The denture base may be of vulcanite, a cellulose compound, or metal. The balata layer may be applied as a thin sheet to be cut to shape and pressed into contact with the denture base, or to be secured thereto by means of balata solution, or may be applied in the form of a series of coatings of a thick solution of balata in benzol.  In the case of a vulcanite denture the balata layer may be applied before the denture is vulcanized but in this case a thicker layer should be used so that the outer part may not become vulcanized by taking up sulphur from the vulcanite composition. The balata layer may cover the whole, or only part, of the surface of the denture, and if used with a suction denture is formed with apertures to expose the suction discs of the denture.

Abstract: 465,475. Uniting metal to vitreous material by heat. BRITISH THOMSONHOUSTON CO., Ltd., and SCOTT, W. J. Nov. 6, 1935, No. 30713. [Class 36] In the manufacture of a high pressure vapour electric discharge lamp of the kind wherein the envelope consists of a tube of quartz or high melting-point glass of relatively small bore and contains an electrode having a composite lead-in conductor comprising a section of thin and fragile metal ribbon connected to the shank of the electrode, the electrode is maintained in the desired position within the envelope prior to the sealing operation by means of a bead or tube of fused silica engaging the inner end wall of the envelope and located or fused around at least a part of the shank of the electrode so as to counteract bending of the electrode with or about the metal ribbon, a portion at least of the silica bead or tube being subsequently incorporated in the seal effected by the fusing down of the end wall portion of the envelope. A thicker lead-in conductor may be secured to the end of the metal ribbon remote from the shank of the electrode, and the silica bead or tube may surround the entire length of the ribbon and preferably extends also over a part ofthe thicker lead-in conductor. The thickness of the metal ribbon is preferably less than 0À008 inch. In the example, a quartz tube 1 which is closed at one end has an electrode 2 near that end provided with a tungsten shank 4 connected to a molybdenum ribbon 3 which, at its other end, is connected to a thicker molybdenum section 5. A tube 6 of fused silica fitting fairly tightly within the tube 1 is located closely around the entire section 3 and extends over part of the sections 4, 5. A co-operating electrode 2<1> has corresponding lead-in sections 3<1>-5<1> located within a silica tube 6<1>. The open right-hand end of the tube 1 is connected to an exhausting pump and then to a supply of the requisite-filling gas, after which the portions of the tube 1 surrounding the tubes 6, 6<1> are heated to fuse them together, and the tubes 6, 6<1> will, in turn, fuse down on to the sections of the composite conductor which they surround. The excess end portions of the tube 1 are broken off to receive metal terminal caps which are connected to the outer ends of the wires 5, 5<1>. An additional hole or holes may be provided in the fused silica tube or bead to receive a further molybdenum lead or leads. Alternatively, a further lead or leads may be sealed in the space between the tube or bead and the lamp envelope. A quantity of mercury may be inserted in the tube 1 before sealing. Specifications 418,906, [Group XI], and 455,101, [Group XL], are referred to.
