Title: Electrostatic water treatment system
IPC: B03C5/00
Filed: 1977-01-19
Abstract: 1527692 Supply and protective circuits for water purifiers PROGRESSIVE EQUIPMENT CORP 19 Jan 1977 02164/77 Headings H2H and H2K [Also in Division C7] An electrostatic water treatment system comprises a capacitance formed by an electrode 1 having an insulating coating 2 and a grounded electrode 3, a power supply for charging the insulated electrode to a high positive D.C. voltage relative to the ground electrode, and a circuit for switching on the power supply when the voltage drops to a lower limit and switching off the power supply when the voltage rises to an upper limit thereby providing a small alternating voltage superimposed on the D.C. voltage when the D.C. voltage is adequate to treat the water. The high D.C. voltage is provided by a transistor oscillator 7 and a D.C. multiplier 6. An operational amplifier 14 compares a proportion of the high D.C. voltage with a reference voltage from a potentiometer 22. If the reference voltage is exceeded a transistor 23 is turned on which turns off a transistor 10 to switch off the high voltage D.C. The capacitance formed by the electrodes then discharges and the alternate charging and discharging of the capacitance causes an alternating current to flow through a resistor 24. The alternating current is detected by an operational amplifier 31 which prevents a transistor 35 conducting and therefore prevents illumination of a lamp 36. In the event of a short circuit between the electrodes, the high voltage at an input terminal 27 of an operational amplifier 26 causes this amplifier to switch on the transistor 23 thereby switching off the high voltage D.C. supply. Also, the absence of the alternating voltage across the resistor 24 causes the illumination of the lamp 36.

Title: Improvements in liquid fuel burning devices of the fuel pressure type
IPC: F23D11/44
Filed: 1943-02-10
Abstract: 565,706. Vapour burning lamps. ALADDIN INDUSTRIES, Ltd. Feb. 10, 1943, No. 2234. Convention date, Feb. 19, 1942. [Classes 75 (i) and 75 (iv)] [Also in Group XXIX] In a liquid fuel burner apparatus, such as a lantern, comprising a fuel reservoir 10 under air pressure, a vapour generator 35, a mixing chamber 27 for air and fuel, and a burner connected to the mixing chamber, the delivery of atomized fuel and air through the generator to the burner for preheating the generator and liquid fuel through an independent passageway in the reservoir to the generator during normal running are selectively controlled by valve mechanism 11. Air is supplied to the mixing chamber through tubes 16, 17, both of which are open when kerosene or heavy fuel is burnt and one of which may be closed by a pivoted shutter 18 when petrol or light fuel is burnt. The lantern shown comprises a perforated base-plate 13 supported by a perforated metal sleeve on the reservoir and the valve mech. anism 11 and forming a seating for the lamp chimney 15. The tubes 16, 17 are rigidly secured at their lower ends to the base-plate 13 and at their upper ends to a metal block 20 carrying a yoke 21, to which hood members 24, 25 are secured above the chimney 15 by a screw 23 and nut 26. The valve mechanism 11 comprises a housing formed with passages 49, 52 communicating with open-ended tubes 38, 39 in the reservoir 10. The tube 38 is packed with fibrous material and communicates by an aperture 44 with a surrounding tube 41 having an aperture 42 above the fuel level. On turning the valve spindle 36 of the mechanism 11, a threaded member 46 first uncovers a seating 48 to allow a mixture of air and atomized fuel to pass from the tube 38 to the generator 35. This mixture is ignited at the burner by a match or taper inserted through an opening in the base-plate 13. When the generator 35 is sufficiently heated, a further rotation of the spindle 36 withdraws a spring-pressed valve member 50 from a second seating 51 in the valve housing and allows fuel to pass from the tube 39 to the generator 35, the flow of air and atomized fuel from the tube 38 then ceasing. The generator 35 is constructed as described in Specification 565,717 and communicates with a nozzle 22 slidably mounted in a guide tube 59 carried by the block 20. The nozzle tip 22b is provided with a minute discharge aperture, the atomized fuel jet from which does not diverge sufficiently to impinge on the wall of the mixing tube 27 and has an aspirating effect dependent on the location of the lower end of the tube 59 relatively to the discharge ends of the tubes 16, 17. The barrel of the fuel reservoir air pump fits in a sleeve on the fuel reservoir and has a flanged end engaged by a flanged collar screwing on the sleeve.
Patent GB-1013895-A (GB)
Title: Externally coating elongate articles with particulate materials
IPC: B05D1/24
Filed: 1964-01-17
Abstract: Elongate articles such as pipes and rods are coated by immersion in a bed of dry particulate material which is maintained in a state of aeration between that of a fluidized bed and of a loose settled unaerated bed, the articles being supported and rotated while immersed in the bed, the adhering particles being subsequently converted into a coherent coating layer.  The articles are preferably preheated to cause adherence of the particles but in the case of non-thermoplastic materials the articles may first be coated with an adhesive and while still tacky immersed in the bed of particles. Further adhesive material may then be sprayed over this coating layer.  As a further alternative electrostatic coating methods may be employed to cause adherence.  Pipes or rods may be rolled through an aerating vessel containing the bed of particles while supported on narrow-edged or toothed rails which minimize the damage to the coating (Figs. 1-3, not shown).  Any such damage may be repaired by subsequent heating and compacting operations.  Alternatively the ends of the pipes may be supported in and rotated by suitably shaped cup or cone members which may be suspended from overhead rails or supported on lateral supporting rails, Figs. 9-12 (not shown). Immersion in the bed may be achieved by raising the bed or by lowering the articles into the bed and is preferably to a depth of at least two inches but to less than two-thirds of the pipe or rod diameter.  The bed of particulate material may be stirred at its base, Figs. 13-15 (not shown), to ensure uniform conditions throughout.  The articles may be heated further after immersion to fuse the coating particles into a coherent layer.  In a preferred method the material adhering to the surface of the article is compacted before or during final fusion of the coating by contact with a smooth surface, e.g. that of a presser roller, Figs. 18-21 (not shown), or of a ramp on which the article may roll from the coating vessel, Figs. 1 and 16 (not shown).  After fusion of the coating is complete the article is preferably cooled by immersion in water while supported on a resilient material, such as foam rubber, Figs. 1, 15 and 16 (not shown). Air cooling may also be employed. Coating materials referred to include thermoplastic powders such as polyethylene, polyvinylchloride, chlorinated polyethers, fluorocarbon resins, nylons, heat-curable resin powders such as partly cured epoxy resins, wax powders, and powders of bituminous substances such as coal tar pitch and petroleum bitumen.  Unfusible materials such as glass beads, sand, abrasive minerals and the like are referred to. Two aerating vessels may be arranged in succession to produce multi-layer coatings and a bath of primer substance may precede the aerating vessel.
