Title: Improvements in devices for introducing superheated steam into the fuel-air intake of internal combustion engines
IPC: F02B47/02
Filed: 1945-10-19
Abstract: 608,868. Treating charge. KUPP, J. Oct. 19, 1945, No. 27546. Convention date, Nov. 10, 1944. [Classes 7 (ii), 7 (iii) and 7 (vi)] The commencement of the addition of superheated steam to the combustible mixture is controlled by a thermally-responsive element, the supply of steam being then controlled by a valve operated in accordance with the combustible mixture throttle valve. Water from a float-chamber 20 flows through an atomizing nozzle 18 and past valves 17, 15 to a heater 5 in the exhaust pipe 1, where it is converted into superheated steam which passes to the intake pipe 8 between the carburetter and the cylinder. The valve 15 is kept closed by a bi-metallic spring 34 until the engine block temperature is such that condensation of the steam will not take place in flowing to the cylinder. The valve 17 is controlled by a lever 29 connected to a lever 31 actuated by a rod 32 carrying a roller 42 co-operating with a cam 43 which rotates on opening of the throttle valve in the intake pipe 8. A throttle valve 11, connected by levers 13, 14, to the lever 31, controls the flow of atomised water through passage 10 to the heater 5, and crankcase vapours may be added to the water through a pipe 38. Atomising air enters through a manually-operated valve 25, and heatinsulating strips 48, Fig. 2, having flutings to reduce their contact area, are inserted between the exhaust pipe 1 and the water container 20 to prevent the water therein being converted to steam. The heater comprises metal guides 5 spaced apart by pressedin grooves. The Specification as open to inspection under Sect. 91 states that the steam may be formed by an electric heater, but this subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to apparatus for the electrical precipitation of suspended particles from gases
IPC: B03C3/16
Filed: 1939-10-17
Abstract: 533,197. Electrical precipitation apparatus. LODGE-COTTRELL, Ltd. (Research Corporation of New York.). Oct. 17, 1939, No. 28074. [Class 39 (i)] The gases under treatment are moistened in the treating chamber with a fine liquid spray, and a shield is so positioned as to prevent impingement of the spray on the discharge electrode. The horizontal flow type of apparatus, shown in Fig. 2, comprises parallel plate collecting electrodes 14 grounded through the casing 10, discharge electrodes 15, and nozzles 22 producing a fine liquid spray consisting of water, aqueous solutions or non-aqueous liquids such as oils. Shields 23 are disposed above the spaces between the collecting electrodes so as to cover the supports 16 of the discharge electrodes. These supports are carried by insulators in heated compartments at the sides of the casing, and have fine points or other attenuated discharge elements to prevent the deposit thereon of solid or liquid particles. The gas inlet and outlet are covered with perforated plates and a baffle plate 26 is provided in the hopper to provide uniform distribution of the gas flow. Arch-shaped members 27 straddle the supports 16 where they emerge from the inter-electrode spaces to provide a more uniform electric field at these points and prevent arcing. The shields 23 may be in the form of liquid reservoirs for flushing the collecting electrodes and may be supplied by the spray or by separate pipes. The invention is also described as applied to upward flow apparatus both of the plate and pipe types. In the modification shown in Fig. 6, the liquid spray is produced by two oppositely-rotating rollers 80 dipping into a liquid pool 81, and the spray is suppressed under the discharge electrodes 74 by shielding plates 82. Specification 504,396 is referred to.
