Title: An arrangement utilising electric dipoles and processes for the production of such an arrangement
IPC: H01Q15/00
Filed: 1964-06-29
Abstract: 1,072,366. Aerials. SIEMENS - SCHUCKERTWERKE A.G. June 29, 1964 [June 28, 1963; April 15, 1964], No. 26879/64. Heading H4A. [Also in Division G2] An arrangement, Fig. 1, comprising a number of short (1 mm. or less) conductive rodlets embedded in substantially parallel formation in a relatively non-conductive rigid carrier substance can transmit deci-millimetric or infra-red electromagnetic (E.M.) waves of frequencies not less than 3 x 10<SP>11</SP> c/s. whose electric vector is perpendicular to the rodlet axes, but will scatter or reflect E.M. waves whose electric vector is parallel to the rodlet axes, said rodlets functioning as electric dipoles. Typical transmission and reflection curves are illustrated in Figs. 2 and 3, respectively (not shown). As described, a molten eutectic of a semi-conductor material with another material which tends to form conductive rodlets on crystallizing is formed and allowed to solidify by a normal freezing process. The parallel orientation of the rodlets may be assisted by, for example, the application of a magnetic field, or by freezing the melt in a flowing condition. Suitable combinations of semi-conductor materials/rodlet materials for such eutectics are indium antimonide/antimony or an antimonide of chromium, iron, manganese or nickel, gallium antimonide/antimony and germanium/cobalt or nickel. In another embodiment, a combination prepared as described above is treated with a solvent which removes the semi-conductor and the recovered rodlets are re-embedded in another carrier substance, such as glass. A transmission filter prepared according to the second embodiment consists of indium antimonide with 1À8 % by weight of nickel antimonide, the latter forming rodlets of diameter about 1 micron (Á) and lengths from 10Á to 50Á. When a reflection filter is required, e.g. for use with a laser, the density of the rodlets in the carrier substance is preferably greater than for a transmission filter, and the material of which they are composed, ferromagnetic. A eutectic of indium antixnonide and mangauese antimonide, containing approximately 6% by weight of the latter may be used.

Abstract: 635,856. Domestic fireplaces. TATE, S. M., (Dollinger, L. L.). Oct. 10, 1947, No. 27249. [Class 126] [Also in Group XIII] A fireplace comprises the combination of a construction made in part from sheet material adapted to form a combustion chamber which is open at one side, and an air-heating chamber, a heat exchanger situated in the air-heating chamber between the combustion chamber and an outlet flue for the combustion products, and adjustable combustion-regulating means adapted to enclose the open side of the combustion chamber. In the form shown, a combustion chamber comprising cast iron or sheet metal panels 8, 9 and an outer shell formed from panels 25, 27. of tile and mortar on a sheet metal backing are built up on a hearth 5, also of tile and mortar on a sheet metal backing and with a bottom layer of asbestos or similar material enabling the hearth to be supported directly on the floor or the joists as desired. The space between the outer shell and the combustion chamber forms an air-heating chamber in which is located a heat exchanger comprising tubes 15 connected to headers 12, 14. The products of combustion from the fire flow through the heat exchanger, the header 14 leading to the outer flue. In one arrangement, air enters through the lower grilles 26, 30, 31, in the panels 25, 27 and flows upwardly before being discharged through similar grilles at the tops of the panels. Alternatively the air may be induced by a fan 45 through the top grilles and discharged through the lower grilles. In the former arrangement, the dampers 51 are turned to the positions shown by dotted lines in Fig. 3, both dampers being simultaneously controlled from a central control rod 48 operated from the front of the outer casing. The flow of combustion air to the fire chamber is controlled by means of a front closure, slidable vertically in guides 39 (Fig. 6) and comprising a plurality of glass louvres 40 mounted on a frame and each rotatable about its horizontal axis to a " closed " or " open " position. The louvres are arranged in three sets, all the louvres in one set opening or closing simultaneously by means of links. When in the closed position, edges of adjacent louvres are spaced slightly apart to allow air to pass over the inner surfaces of the louvres to prevent the formation of soot thereon.

Abstract: 1464225 Supply systems for discharge lamps J CATES 27 June 1975 27364/75 Heading H2H In order to enhance the starting of a high pressure mercury halide discharge lamp the conventional thermally operable starting device is associated with an electromagnetically operated relay so as to shorten the starting period. A mercury halide lamp 1 is connected to an A.C. source 3, 4 by way of a ballast inductor 2, the heating coil 11 of a thermal starting switch 6 being connected across a part of the inductor 2. The normally closed contacts 8, 10 of the thermal switch 6 are connected in series with the operating coil 14 of an electromagnetically operated relay 15 across the A.C. supply 3, 4 with the normally open contacts 16, 17 of the relay 15 connected across the lamp 1 and a capacitor 12 connected across the contacts 16, 17. On switching on current flows in the coil 14 of the relay 15 to close contacts 16, 17 so that the inductor 2 is connected across the supply. When the thermal switch 6 is sufficiently heated its contacts 8, 10 open whereupon relay 15 is de-energized. The subsequent opening of the relay contacts 16, 17 breaks the circuit for the inductor 2, the resulting voltage pulse causing the lamp 1 to start. The apparatus of the invention allows the components of the thermal switch 6 to carry smaller currents than those in the thermal switches of conventional apparatus for starting high pressure mercury halide lamps. With a capacitor 5 connected across the A.C. terminals 3, 4 as shown in Fig. 3 the apparatus is suitable for use on a 415 volt A.C. supply and with a capacitor 13 connected in series with the inductor 2 as shown in Fig. 5 the apparatus is suitable for use on a 240 volt A.C. supply. In other embodiments the heating coil 11 of the thermal switch 6 may be connected across a small auxiliary inductor in series with the inductor 2 and a further capacitor and a resistor may be connected in series with the capacitor 12.

[Class 38 (v)] [See also Groups XIII and XI] An electrically-heated device, more particularly a heating-pad is provided with a thermal switch controlling the main heating circuit, and an auxiliary heater for the thermal switch which is independent of the operation of the thermal switch and is controlled manually. The heating resistance 10 of the pad is in series with two thermal switches 15, 16, each comprising a bimetallic strip 17 secured to but insulated from a support 18 and carrying a contact 22 formed by bending over the end of the strip. The fixed contact 24 may be a tongue projecting from the support 18, adjustable by a set-screw 25. The switch is enclosed in a copper casing 32. Each switch is provided with a heating coil 35 wound over the casing 32, and the heaters are energized through a carbon pile resistance 36. A pivoted lever 40 co-operates with the resistance 36 and with a contact 42, so that the current supplied to the heaters 35 may be varied while maintaining the supply to the heaters 10 constant. The heat received by the strips 17 from the heaters 35 becomes proportionally less as the lever 40 is moved to the left so that more heat must be supplied by the heaters 10 to break the circuit, and the temperature of the pad may thus be varied. The actual temperature at which the thermal switches open is higher than the temperature of the pad. Specification 195,974, [Class 38 (v)], is referred to.
