Abstract: 836,991. Coating with metals. TELEPHONE MANUFACTURING CO. Ltd. Nov. 29, 1956 [Dec. 5, 1955], No. 34771/55. Class 82(2) [Also in Group XXXVI] A coating deposit is produced upon a limited area of a web-like support by holding a first length of said support in contacting overlapping relation with a second length of said support, moving said lengths past means for effecting said deposit upon portions of both lengths whereby the second length serves as a mask to prevent deposit upon the overlapped area of the first length and itself receives a deposit over only an edge region thereof and simultaneously a non-overlapped area of the first length receives a deposit, and subsequently moving the second length past means for effecting a further deposit thereon which at least partly overlies the deposit previously received over said edge region. As shown, paper or polystyrene web 10 which acts as the first length is fed from roll 11 to take-up roll 16, being pre-metallized at station 19 with e.g. silver or other metal of Group 1B or 4B, and coated at station 18 by carbonyl decomposition or thermal evaporation with e.g. cadmium. The second length of web 21 is fed from roll 22 to take-up roll 23 and masks part of length 10. In alternative embodiments (i), the two lengths are wound together on the same rolls, and (ii), the two lengths are constituted by adjacent widths of a single support which is folded lengthwise so that one width overlaps part of the other. Reference is also made to the deposition of dielectric coatings, e.g. of lacquer, upon metallic supports. The process is applicable to the production of capacitor electrodes.

Title: Improvements relating to the regulation of compressors or pumps working in parallel
IPC: F04D27/02
Filed: 1921-12-29
Abstract: 173,520. Graemiger, B. Dec. 30, 1920, [Convention date]. Pumping-machines; regulating. - A centrifugal compressor or pump 2 delivers into a conduit 1 and an auxiliary pump of any type works in parallel with it delivering into the same conduit. The drive of the auxiliary pump is controlled by the quantity delivered by the centrifugal pump so that the latter pump works under desired conditions. The compressor 2, Fig. 2, is driven at a constant speed by an electromotor 4, and a volume-meter 6 on the suction side of the compressor is connected by the pipe 9 to the vessel 8 below the diaphragm 7, the space above the diaphragm being open to the atmosphere. A rod 11, attached to the diaphragm, is connected to the rod 13 of the valve 14 which controls the admission of pressure oil to a servo-motor 15 which in turn operates the valve 17 of the piston engine 5 driving the auxiliary pump 3. The apparatus is set so that the output of the centrifugal compressor 2 does not exceed a certain value. As soon as the output of the compressor rises, the diaphragm 7 falls and the valve 14 is displaced to permit oil to enter below the piston 16 to raise the valve 17. This admits more fluid to the engine 5 so that the delivery of the auxiliary compressor 3 is increased. Instead of operating the valve 17 the regulating device may operate a throttle valve on the auxiliary compressor. In a modification the compressor 2 is driven by a steam turbine, and the regulating device, which operates a throttle valve in the admission pipe of the auxiliary machine, is responsive to variations in the volume-meter and to variations in the discharge pressure. In another modification the auxiliary compressor is driven by a steam turbine 5 with an admission valve 15 controlled by the regulating device. The pressure in the meter 6 operates the diaphragm 8 and the valve 10 thereby allowing oil to flow to rotate the motor 11 in one direction or the other. The motor 11 operates the valve 15 through the gearing 21, 20, 18, while the valve is also under the influence of the governor 12 through the valve 13 and servo-motor 14.

Abstract: 1387470 Induction heated cooking apparatus, inverters MATSUSHITA ELECTRIC INDUSTRIAL CO 26 July 1972 [10 April 1972 (3) 11 April 1972 12 April 1972] 35004/72 Heading H2H and H2F [Also in Division H1] Cooking apparatus comprises a utensil 33 heated by means of an induction heating coil 31 carried below an electrically insulated non- metallic plate 57 the coil 31 being energized by way of an inverter fed from a rectified A.C. source 20, the power delivered to the coil 31 being controlled by an adjustable inductor 34 and all the components of the rectifying-inverting circuit being housed in a metallic screening device 58, 59 to eliminate interference with other electrical apparatus such as a radio. The inverter comprises an A.C. source 20, and a full wave rectifier 28 which produces D.C. on lines 24, 25 by means of which a capacitor 29 is charged when a thyristor 53 is gated on. When the thyristor 35 is gated on, the capactior 29 discharges and charges in an oscillatory fashion by way of an inductor 30 thus providing a high frequency supply for the induction coil 31. When a main switch 21 is closed a thyristor 52 is gated on and a capacitor 50 of a zero volts circuit 45 charges up over a resistor 48. When the capacitor voltage reaches a predetermined level a transistor 49 is triggered on to render the thyristor 52 non-conductive when the voltage thereacross falls to zero. On becoming non- conductive, thyristor 52 causes thyristor 54, and hence thyristor 53, are gated on at zero voltage. Capacitors 29, 26 now charge up, the charging of the capacitor 26 causing thransistors 55, 56 to assume such states that a capacitor 40 charges over a variable resistor 41. At a predetermined capacitor voltage, a device 42 breaks down to gate a pulse amplifier 38 whereby a pulse is produced in the primary winding 37a of a transformer 37, the associated pulse in the secondary winding 37b gating on a thyristor 43. A gating on pulse is then produced for the thyristor 35 whereupon the capacitor 29 discharges and charges in an oscillatory manner at a frequency determined by the parameters of the capacitor 29 and the inductor 30 whereby to energize the induction heating coil 31 at a value determined by the adjustable inductor 34. More than one coil 31 connected in series or in parallel may be energized. In order to eliminate interference with other electrical apparatus all the circuit elements with the exception of the induction heating coil 31 are housed in metal housing 58, 59, one inside the other and insulated from one another by members 61, the electrical connections through the inner housing 58 being provided with condenser bushings 60. The induction heating coil 31 is supported by means of a glass plate 57 at a predetermined distance therefrom and the upper surface of the plate 57 may be provided with an earthed metal foil member whereby the cooking utensil standing on the plate is earthed.
