Title: Improvements in or relating to electric circuit arrangements for starting and operating electric discharge lamps
Inventor: CATES JULIUS
IPC: H05B41/10
Filed: 1954-02-11
Abstract: 758,211. Supply systems for space discharge lamps. GENERAL ELECTRIC CO., Ltd. Feb. 11, 1955 [Feb. 11, 1954], No. 4071/54. Class 38 (4). In a discharge lamp starting and operating circuit to avoid lamp extinction due to dropping out of the usual starting switch when the supply voltage is low, e.g. in vehicle lighting systems where a generator output or the state of a battery charge may vary, one or more series connected heatable electrode electric discharge lamps 9 are serially connected with the coil 4 of an electromagnetic relay 5 to supply input terminals 1, 2, and a part or the whole of the coil 4 is shunted by the series connection of normally closed contacts 14 of the relay 5 and normally closed contacts 13 of a thermal starter switch 11 whose resistance heater 10 is serially connected with a further pair of normally closed contacts 12, of the relay 5 between and in series with the lamp electrodes 7, 8 to complete an electrode heating circuit; on energization of the circuit heating current flows through the electrodes 7, 8, the heater 10 and contacts 12 initially via the coil-shunting contacts 13, 14, but when after a time delay the heater 10 causes contacts 13 to open the current then flows via the relay coil 4 which then opens its contacts 12, 14, the former of which produces a high voltage pulse from the relay coil to start the lamp while the latter ensures that the lamp discharge current flows through the relay coil when the contacts 13 reclose during running. If the circuit is operated on an A.C. supply the relay coil 4 provides the whole of the lamp ballast impedance, while if operated on a D.C. supply a ballast resistor 3, e.g. a tungsten filament lamp is connected between the relay coil and one supply terminal 1. Where the circuit is for operating a chain of series connected lamps there is provided a respective said further pair of normally closed relay contacts for each lamp so that all the electrodes form a single heating circuit. In a modification, to allow reversal of the supply when it is D.C., the relay coil is split into two halves, one of which is connected where the coil 4 is shown, and the other is connected between the terminal 2 and electrode 8 and is shunted by a farther normally closed relay contacts. Locking out of the circuit should the lamp not function may be provided as shown by a thermal lock-out switch 27 having a heater coil 29 and bimetallic and spring contacts 32, 33 serially connected between the heater 10 and contacts 12, the contact 33 unlatching from contact 32 when the latter bends away in response to repeated starting operations, and needing to be reset by a control button 34; or alternatively, not shown, by the series arrangement of a current-limiting resistor and a pair of normally open relay contacts shunted across the lamp. The Provisional Specification refers to Specification 652,500.

Filed: 1971-02-10
Abstract: 1396293 Thermal storage heaters; central heating systems; cooling buildings J E RANDELL 2 May 1972 [10 Feb 1971 1 April 1971] 4335/71 and 8438/71 Headings F4U and F4H A thermal storage apparatus is used directly or indirectly as the heat or cold source of a forced, warm or cold air system, or hot or cold liquid system for heating or cooling a building by the use of a refrigeration system of the absorption or compression type, which latter may be used as a heat pump. In a simplified form, a thermal storage vessel 1 containing a freezable liquid, e.g. water and an immersion heating element 2, also houses the evaporator 3 of a compression refrigeration system formed by a compressor 5, a heat exchanger coil 6 and restrictor 7. Flow of liquid from the vessel to a heat exchanger 4 is controlled by valves 8, 9. The heat exchangers 4 and 6 are parallelly arranged for air to be blown thereover by a fan 11. During the heating cycle heat is extracted from the vessel until the liquid therein is at ambient temperature and the compressor is operated and used as a refrigerator extracting further heat including the latent heat of fusion of the water on freezing. The ice is then melted and the water heated by the heater 2. If cooling is required, the water is frozen overnight by the refrigeration system, and the heat exchanger 4 with or without the fan 11 will extract heat from ambient air during the day. Many embodiments are described including additional heating elements, either an electric heater element or a further heat-exchanger, incorporated in the vessel. Air passages may be formed within the vessel and the freezable liquid may be mounted in pockets surrounded by heat transfer medium. Many examples of salt hydrates added to the water are described as are polyethylene oxide and solids of high thermal conductivity. Specification 1,396,292 is referred to.

Title: Tubular carbon articles
Inventor: BICKERDIKE ROBERT LEWIS
IPC: B32B18/00
Filed: 1959-02-10
Abstract: Composite carbon tubes are made by treating at least one component tube to deposit carbon in the pores thereof in at least an annular surface region so as to render the component tube substantially impermeable in this region throughout its length, and uniting the treated tube with another component tube by means of a carbon bond, the component tubes being arranged so that the impermeable region of the treated component tube does not form part of a cylindrical exposed surface of the composite tube.  The bond may be an adhesive formed by polymerizing a liquid organic compound to solid state and carbonizable without passing through a liquid phase, e.g. furfuryl alcohol.  Alternatively the bond may be created by depositing carbon by pyrolysis of the vapour of a hydrocarbon compound.  Deposition of carbon in the pores of one component tube may be effected either by impregnating with an organic liquid, e.g. furfuryl alcohol, followed by polymerization and carbonization or by pyrolysis of a hydrocarbon vapour in situ. Examples are given.  Specifications 881,404, 901,847, 901,848, 928,532, 929,463 and 929,464 are referred to.

Title: Improvements in percussion tools
IPC: E21B1/28
Filed: 1961-01-02
Abstract: 974,930. Percussive tools. ATLAS COPCO A.B. Jan. 3, 1961 [Jan. 5, 1960], No. 4671/64. Divided out of 957,204. Heading B4C. A percussive tool has a housing 1, a working cylinder 6 in the housing, a hammer-piston 7 reciprocable in the cylinder under the action of a pressure fluid, a working implement 16 actuated by the hammer-piston, and a distributing valve 27 arranged to distribute fluid to the portions 9, 8 of the cylinder to reciprocate the hammer-piston with rapid working strokes and slower return strokes and to vent the fluid cushions formed at the ends of the strokes. The tool may be actuated pneumatically, hydraulically or by steam pressures. A handle member 18 has guide rods 84 slidable in the housing, and engages rubber caps 83a on rods 83 of damper pistons 23 which slide in bores 24. As soon as the tool is connected at 30 to an air supply, air passes through duct 76 to chambers (not shown) leading to chambers 73 having outlets 79 larger than the inlets to the other chambers. A low pressure develops in the chambers 73 when the outlets are uncovered by the pistons so that the pistons and chambers constitute vibration damping means for the handle member. Pressure on a trigger 54 operates a valve 50 to vent a passage 89 communicating by means of a sliding tube 90 with a chamber 57 of a valve 43 to actuate the valve 43 and connect the air supply to a duct 32 and the valve 27. If the tool is lifted by the handle member, holes 92 in the tube are closed by bush 93 so that the chamber 57 is not vented, and air is not supplied to the valve 27 to reciprocate the hammer-piston. Air reaching the valve 27 when in its upper position (shown) passes through duet 97 into the portion 8 to give the hammer-piston its working strokes whilst air escapes from the portion 9 through port 99 and duct 101. The valve 27 is moved to its lower position as a port 94 is uncovered during the working strokes. With the valve 27 in its lower position air passes through port 99 to portion 9 and escapes slowly from portion 8 through duct 100 to cause the hammer-piston to make the return strokes, the valve 27 being returned to its upper position as the hammerpiston passes a port 95. The portions 8, 9 are connected to exhaust ports (not shown) as the hammer-piston passes grooves 102, 103, and the portion 9 is connected to a reservoir 105. An anvil block 11 is interposed between the hammer-piston and the implement which is held by a retainer 14.
