Title: Metallisation of Ceramic Materials
Inventor: CAPPELLETTI CARLO
IPC: C04B41/88
Filed: 1967-01-10
Abstract: 1,166,820. Metallizing ceramics. EUROPEAN ATOMIC ENERGY COMMUNITY. Jan.10, 1967 [Jan.18, 1966], No.1282/67. Heading C7D. In a method of metallizing ceramics e.g. high purity alumina (>99À5% Al 2  O 3 ), a layer of metal powder e.g. W, the particles of which are oxidized on their surfaces, is formed on the surface of the ceramic and heated to sinter the powder and effect a reaction between the oxide and the ceramic and reducing the surplus oxide. In an example, W powder 1 micron size is oxidized to a weight increase of 1-5% and suspended in carbon tetrachloride, amyl acetate, acetone, alcohol or water. The Al 2 O 3  ceramic is washed in nitro-hydrochloric acid and water, and baked at 1200‹C. The W suspension is applied to the ceramic in a layer 10 to 20 microns thick. Sintering is effected in a N 2  /H 2  humidified atmosphere at 1800‹ - 1950‹C. Cooling from 1700‹C. is effected in a non-humidified atmosphere. In an alternative embodiment the suspension of metal powder may be oxidized by infrared heating after application to the ceramic surface.

Title: Improved control system for an electric heater element
IPC: G05D23/275
Filed: 1955-01-19
Abstract: 764,426. Automatic temperature control systems. GENERAL MOTORS CORPORATION. Jan. 19, 1955 [Feb. 2, 1954], No. 1628/55. Class 38 (4). [Also in Group XXXVII] In a system for automatically controlling an electric heater element, the heater element is either disconnected or has one or other of two voltages applied to it according to the temperature of a vessel on the heater element. In Fig. 2, the temperature of a cooking vessel 48 on a two-resistance electric heater element 46 is detected by a liquid-filled bulb 44 spring urged into contact with the bottom of the vessel. An expansible metal bellows 36 coupled by a capillary tube 42 to bulb 44 opens contacts 30, 62 to de-energize a relay 68 at a temperature determined by the setting of a cam 34 by a knob 131. This changes the connection of the two heater resistances from a source Ll L<SP>2</SP> to a source L<SP>2</SP>N of half the voltage. The desired temperature is thus maintained by alternate energization at the two voltages. If for any reason the temperature of the vessel rises a predetermined amount above the desired value, bellows 36 operate sufficiently to open contacts 32, 58 and de-energize the heater resistances. Over the lower portion of the. temperature range which includes " slow boiling," a cam 125, also operated by knob 131, opens contacts 86, 98 so that only one heater resistance is energized when contacts 30, 62 are open.

Abstract: 886,746. Discontinuous coatings; laminates. STAFLEX CO. Ltd. Jan. 20, 1958 [Jan. 19, 1957], No. 2056/57. Drawings to Specification. Class 140. A fusible interlining material is produced by a method which includes the steps of distributing over the surface of a support fabric or other flexible support sheet material a softenable synthetic resin in divided form and subjecting the resin to the action of a softening medium so that the resin coalesces to bond to the support material to form a discontinuous layer of discrete non-tacky nodules without substantially affecting the porosity of the support material. The particles of synthetic resin may be distributed evenly over the surface, in the form of discrete piles of powder, or as already formed nodules of the desired size. The synthetic resin may be thermoplastic, e.g. polythene, or a vinyl copolymer, which may be plasticized or may be mixed or blended with polymers, synthetic rubber or other suitable material. A solution or emulsion of the plasticizer may be sprayed on to the support material prior to the application of the resin, or the resin in divided form may be treated with the plasticizer solution or emulsion to produce a surface layer on the resin particles. The resin particles may be mixed powdered plasticizer or powdered plasticizing resin. The synthetic resin may be thermosetting which when heated will soften and cure to the " A " stage. The support material may be impregnated with a thermoplastic resin and then partially or fully dried prior to the application of the resin in divided form. The softening agent may be heat or other media, e.g. solvent which may be applied to the support material or resin either before or after the application of the resin to the support material. The nodules of resin may be evenly distributed over the whole or only over selected areas of one or both surfaces. The support material may be a woven textile material such as a cotton fabric. The interlining material may be laminated with a textile or other flexible sheet material so that the nodules lie between the flexible sheet material and the flexible support material by subjecting the synthetic resin to the action of a softening medium whilst the assembly is subjected to pressure.
