Abstract: 1,063,245. Construction and mounting of heating resistances in presses. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. Aug. 27, 1963 [June 25, 1963], No. 33911/63. Heading H5H. [Also in Division D1] A clothes press comprises a bottom member 4 and a top member 2 pivoted thereto by hinges 5 and adapted to be clamped thereto by claws 12 on springs 10. Heating means 3 in the form of a woven cloth of heat-resisting and electrically insulated material, such as synthetic or glass fibres, having an interwoven electric heating winding of, e.g. stainless steel, is provided on the member 4. The heating means 3 is covered by a cushion sheet 40 of a foamed plastic such as polyurethane with a cover 41 of a heat-resisting cloth. Similarly the top member 2 has a cushion 42 and a cover 45. A thermostat 9 is provided for regulating the temperature. The heating wires may be of a readily fusable material which will fuse if the thermostat is out of order. Alternatively, a detecting wire (30), Fig. 16 (not shown), may be arranged alongside the heating wires (29) which on overheating of a part of the cloth, and a consequent reduction in the resistance through the insulation, pass a current to actuate a regulator to cut off the current to the heating wires. Another safety device comprises a pair of resin-coated wires (36), Fig. 18 (not shown), twisted together and connected to opposite sides of the heating wires (16). If the temperature of the cloth rises unduly the resin coating fuses and the wires (36) short-circuit the heating wires. The excessive current blows a fuse (38) in the supply circuit. Alternatively a temperature fuse may be incorporated with the thermostat.

Title: Improvements in or relating to tuned circuits
Inventor: ATTWOOD BRIAN ERNEST
IPC: H03L1/02
Filed: 1954-11-26
Abstract: 759,459. Tuned Lecher lines. MULLARD RADIO VALVE CO., Ltd. Nov. 26, 1954, No. 34347/54. Class 40 (8). [Also in Group XL (c)] A tuned circuit comprises a Lecher line 2 excited at one end bv a thermionic valve and loaded at the other end by a variable capacitor 3 the circuit also including one or more temperature-dependent capacitors shunted across the line at points so located with respect to the position of a voltage node that constant temperature compensation is achieved throughout the tuning range. At the lower end of the range compensation is effected by means of a N.T.C. (negative temperature coefficient) ceramic capacitor 10 which is situated adjacent the valve pins 15. In order that the capacitor 10, which has a relatively high value, should be effective only at low frequencies it is arranged to be situated at a voltage antinode for the low frequencies and at a node for the high frequencies. As the frequency is raised the antinode moves along the line and at the upper end of the range the N.T.C. air capacitor 11 becomes effective. One electrode of the capacitor 11 is connected to one set of stator plates of the variable capacitor 3; the other electrode consists of a bimetallic strip 12 connected to one conductor of the Lecher line. Suitable dimensions for the electrodes are given in the Specification. In operation, as the valve warms up, heat is conducted along a conductor of the Lecher line to the bimetallic strip 12 causing it to bend slightly and reduce the capacitance across the line. Thereafter the capacitance varies with the ambient air temperature. When the circuit forms part of the oscillator of a superhetrodyne receiver a N.T.C. ceramic trimming capacitor 13 may be used in parallel with the capacitor 10. Suitable values for the circuit elements are given in the Specification.

Abstract: 1391107 Distilling hydrocarbons UNIVERSAL OIL PRODUCTS CO 25 July 1972 [26 July 1971] 34692/72 Heading C5E In the separation of vinylbenzenes (e.g. styrene) from alkylbenzenes by distillation with the addition of elemental sulphur to inhibit polymerization, a high-boiling distillation residue containing sulphur is recycled to provide part of the inhibitor. As shown, a stream of fresh ethylbenzene from line 1 and recycled ethylbenzene from line 2 is dehydrogenated at 3. The product is cooled and separated at 5; an aqueous phase is discarded at 6 and a gas phase at 7. The hydrocarbon phase in line 8 with recycled material from line 10 and fresh sulphur from line 9 is distilled in three columns 11, 14 and 16. The distillate from column 11 is mainly benzene and toluene; that from column 14 is mainly ethylbenzene, and is recycled by line 2; that from column 16 is the desired product, styrene. The bottoms from each of the first two columns provides the feed to the next column, that from the third is fed to a wiped-film evaporator 19. Vapours from this evaporator pass back to column 16 by line 20; the residue is in part recycled by line 10 and in part removed by line 21 to avoid the build-up of heavy materials. Alternatively, the wiped-film evaporator can be by-passed by line 22. Distillation is preferably at reduced pressure.
