Title: Energizing circuit for degaussing apparatus
IPC: H04N9/16
Filed: 1967-05-02
Abstract: In an arrangement for automatically degaussing a television picture tube, particularly a shadow-mask colour tube, a capacitor connected to one terminal of a degaussing coil is charged through the coil during alternate half-cycles of the A.C. supply for the apparatus and discharges through the coil into a second capacitor connected to the other terminal of the coil during intervening halfcycles of the A.C. supply. The cyclic reversal of the direction of current flow through the coil thus produces an alternating magnetic field, the magnitude of which decreases towards zero as the second capacitor becomes fully charged. For carrying out the invention a conventional voltage doubler type of circuit supplying the television apparatus with the normal D.C. operating potentials from the A.C. supply is modified as shown in Fig. 2. This modification involves replacing the input capacitance of the circuit by two capacitors 16, 17 and the provision of a linked switch 24-27 mechanically biased by resilient means 35 so that it normally occupies the position shown involving contacts N(= normal). In this position the circuit operates in conventional manner to provide operating D.C. potentials viz. 280V and 140V for the television receiver 15. When degaussing of the picture tube is required, the switch is operated to its other position in which contacts D(=degaussing) are engaged and then allowed to return to its normal position under the action of the resilient means 35. During the short interval for which the D contacts are engaged capacitor 16 is charged through the degaussing coil 13, 14 by alternate half-cycles of the input A.C. (via switch 19) whilst during intervening half-cycles capacitor 16 discharges through coil 13, 14 into a second capacitor 23. This charge and discharge of capacitor 16 continues until capacitor 23 becomes fully charged and the resulting alternating magnetic field produced by coil 13, 14 effects the required degaussing of the picture tube. The coil 13, 14 is mounted on a magnetic shield 12 (Fig. 1) of ferrous metal with the forward portions encircling the shield on the outside and the rear portions disposed on the inside of the shield. Values for the various capacitors are given.

Title: Gas-steam turbine plant
IPC: F02C3/30
Filed: 1967-05-03
Abstract: A turbine plant has a combustion chamber 4 with means for maintaining a water film on the internal wall surface 6 so that steam is produced by the heat of combustion, the steam mixing with the combustion gases within the combustion chamber and flowing through a pipe 8 to drive the plant turbines 46, 47. Turbine 47 drives a generator 15. Combustion air is supplied to the burner 5 of the combustion chamber by turbine driven compressors 1, 3 having an intercooler 2 which pre-heats the water being pumped to the combustion chamber and to an additional water injection point 7 downstream of the combustion chamber. The amount of water injected at 7 is controlled by a temperature sensing unit 9. The exhaust from turbine 47 passes through a heat exchanger 48 to effect further pre-heating of the water. Demineralizers 12, 14 are provided in the water line. The combustion chamber may comprise, Fig. 2 (not shown), an outer casing (16) with insulation (30) surrounding an inner double walled cylindrical or frusto-conical liner (17). The water is fed through pipes (18) to a distribution trough (19) at the top of the liner and thence over the edge of the trough or through drillings to cover the entire internal surface of the liner with a film of water. Any water not evaporated to steam collects in a sump (20) at the bottom of the combustion chamber from which it flows to a balance tank (21). The water level in the tank and in the combustion chamber is maintained constant by a level controller (26, 27). Water is pumped back from the balance tank to the distribution trough (19). The liner (17) is cooled by water in a space (32) between its walls. Additional water is sprayed into the combustion chamber by a nozzle (7). In a modified combustion chamber, Fig.3 (not shown), there are three adjacent liner sections (33, 34, 35) and water is sprayed by nozzles (36) to form a film on the upper liner (33) which runs down to collect in distribution troughs (37, 38) in the intermediate and lower liner sections (34, 35), respectively. In this modification, the internal walls of the liners have indentations of projections or are formed from perforated plate to reduce the velocity of the water film. In a further modification, Fig.4 (not shown), the combustion chamber has several burners 5 and associated liners.

Title: Disengageable electrical connections having improved contact spring means
IPC: H01R31/02
Filed: 1969-09-13
Abstract: Electrical contact sockets 2, Fig. 6, are formed in continuous strips from strip material (44, Fig. 2, not shown) which has a layer of thin metal (46) of good spring qualities with a narrower layer (48) of high conductivity metal bonded to it. The strip of contacts is formed (Fig. 1, not shown) with the narrower layer (48) extending over ears (42) and connecting parts (6, 8, 10), 11 and the carrier strips (6, 8) are folded at 12, 14 to form rows of contacts (Fig. 3, not shown) which may be used for interconnecting wires extending axially towards each other, or the strip may be bent at 16, Fig. 5, to connect parallel wires to a common joint. Groups of sockets 25, 27 may be placed in recesses 26, 28 in an insulating housing 20, the sockets passing into cavities 22, and a cover plate 30 being cemented over the base to hold them in place, the sockets being further held in place by shoulders 64, Fig. 12. A relatively soft sealing block 24 is mounted against the opposite end of the housing 20 and this contains passageways (29, Fig. 8, not shown) which communicate with the cavities 22 for insertion of the contact pins. A contact pin 32, Fig. 12, crimped to wire 34 at 54 and having a circumferential collar 58 and conical end 56, is inserted in socket 2 until shoulder 60 of collar 58 abuts shoulders 63 and 65 formed by the edges of the conductive layer 48 on the surfaces of ears 42 and connecting strip 11. Lances 40 formed in the socket lodge behind collar 58 and against the shoulder 62, to prevent removal of the pin without the use of an extraction tool. Being formed from a double layer of metal, and being connected arcuately with the body 36 of the socket, the ears 42 are rigid and when the pin is inserted stresses are transmitted from the ears 42 to the body 36, which deforms, particularly in the area between the seam 38 and lances 40. The deformed socket acts as a contact spring, maintaining the inner surfaces of ears 42 against the surface of the pin, and the ears bias the end of the pin against the connecting strip 11, the main electrical connection being through strip 11. The contacts may, alternatively, be formed from homogeneous stock metal.

Title: Nuclear turbine steam bypass dump valve
IPC: F01D21/00
Filed: 1974-05-03
Abstract: A fast opening valve for a pressurized fluid line. The valve comprises a body member having an inlet port and an outlet port therein, and a main plug member movably disposed within said body member. An overbalance chamber is defined by the main plug member and the interior of the body member. The overbalance chamber communicates with a dump line through a draining orifice and also communicates with the inlet port when the valve is closed. A pilot plug blocks the draining orifice and isolates the overbalance chamber from the dump line when the valve is closed. The main plug is held in the closed position against the force of a spring bias by a pressurized piston-cylinder arrangement. With the pilot plug blocking the draining orifice, the pressurized fluid collecting in the overbalance chamber exerts a force which assists in holding the valve closed. The valve is opened by a predetermined signal which contemporaneously releases the pressure force holding the main valve plug. The predetermined signal also opens the draining orifice. With the holding force relieved and the pressurized fluid drained from the overbalance chamber, the spring bias impels the main plug to the open position. A hydraulic damper absorbs high impact energies associated with the opening valve.
