Title: Pressurized container pistons
IPC: B65D83/14
Filed: 1978-07-25
Abstract: The invention contemplates a pressurized container for viscous foods or other viscous products 16 in which the body of the piston 18 includes, adjacent the closed head end 17, a flexible circumferential band 20 which expands into light sealing contact with inner surface 10a of the container in the presence of loading pressure exerted by propellant gas 26. This contact effectively isolates unexpelled product from the gas-pressure side of the piston, regardless of the extent to which product has been expelled. The piston further includes circumferentially continuous tail band 19 which is connected to the expandable band 20 by longitudinal ribs 19' and which serves to stabilize the piston against malfunction in the course of its single product- expelling stroke. <IMAGE>
Patent GB-2030230-A (GB)
Title: Power plant
IPC: F02B41/04
Filed: 1978-09-23
Abstract: The power plant consists of a plurality of reciprocating piston compressors 3, with faster compression strokes than suction strokes compressing to self-ignition pressures, in rotating annuli 1, located on jet pipes 21 discharging into one or more common primary combustion chambers 10. The primary combustion chambers exhaust into the jet pipes wherein further fuel and oxidant injection may take place. The compression stage is removed from the ignition, combustion and expansion stages. The mass flows and velocities of the two coaxial jets from the jet pipe 21 and exhaust tube 19 can be varied over several Mach numbers, by regulating the speed of rotation of the annuli. Fuel injection is preferably intermittent, but combustion is continuous in a number of different stages. Ignition and combustion do not take place in closed or intermittently closed cylinders. The preferred use of the invention is for jet propulsion. Each of the two rotating annuli 1 carries compressor blades 5 on its inner wall and turbine blades 4 on its outer wall, air passing to the compressor blades through parts 31 and 12 and air discharging from the turbine blades through ports 27. <IMAGE>

Title: Method of marking on hot material and apparatus therefor
IPC: B41F15/08
Filed: 1979-02-13
Abstract: A method of marking on a hot material 10 and an apparatus therefor wherein a, combustible and flexible stencil 20 is used, water is first sprayed on the end face of the hot material to decrease its surface temperature and thereafter, the stencil is brought close to the end face of the hot material by holders 16, and the marking composition is sprayed from behind the stencil to bring the stencil into close contact with the end face of the hot material for clear marking by utilizing the flexibility of the stencil.

Title: Forced air heating unit
IPC: F24C1/14
Filed: 1978-06-05
Abstract: A free-standing unit (10) for heating air in a U-shaped channel (18, 20, 22) surrounding a fire box (12, 78, 80, 82, 84) having a pair of spaced vertical vents (30, 32) for directing the heated forced air to converge in front of the fire box opening (34) to limit air flow towards said openings. Mesh (31) in the vertical vents (34) directs the forced air downward to be combined with the hot forced air from a bottom horizontal vent (88). A baffle plate (126) depending from the top of the fire-box adjacent the flue port (26) and an opening along the top of the doors ignite the gases adjacent the top and direct some gases back into the fire. By forcing heated air at a low level and drawing cool air from a high level, the air being heated is of a uniform temperature. A hood (66) extending along the top edge of the fire box opening diverts exiting gases back into the fire box. A thermostatically controlled blower (71) creates the forced air and cools the fire box walls.

Title: Furnaces Having Catalytic Heaters
IPC: F23G7/06
Filed: 1979-12-20
Abstract: A sintering or other precision furnace comprises a pre-heat part 10 in which hydrocarbon effluent gases are present, a flue chamber 26 containing a catalytic heater 36, an opening in the furnace chamber 16 and an exhaust 28 external of the furnace. An oxidising gas such as CO2 is introduced into the flue for combination with the effluent gases being drawn out of the chamber. As the contaminating gases move through the flue, they pass over the heated catalytic surfaces of the heater 36 and react with the oxidising gas to form water and carbon monoxide, all of which is drawn out through the flue and exhausted therefrom or burned off. The draft or negative pressure within the flue is closely controlled by an air operated Venturi pump 37, the air of which assists in burning exhaust gases at the exhaust 28. Alternatively, the catalytic heater can be disposed in a gas barrier 14 located between the pre-heat part 10 and high-heat or sintering part 12 of the furnace chamber 16. <IMAGE>
