Title: Cooled blades for a gas turbine engine
Inventor: AUXIER THOMAS ALVIN
IPC: F01D5/18
Filed: 1990-01-09
Abstract: An internally cooled turbine blade for a gas turbine engine is modified at the leading and trailing edge sections to include dynamic cool air flowing radial passageways 30 with an inlet 34 at the root and a discharge 36 at the tip, the passageways feeding a plurality of radially spaced film cooling holes 32 in the airfoil surface. Replenishment holes 38 radially spaced in the inner wall of the radial passageways communicate with internal cooling passages in the blade to replenish the cooling air lost to the film cooling holes. The discharge orifice is sized to match the backflow margin to achieve a constant film hole coverage throughout the radial length. Trip strips may be employed to augment the pressure drop distribution.

Title: Emergency escape breathing apparatus
Inventor: KUGLER SIMON
IPC: A62B17/04
Filed: 1990-07-13
Abstract: In emergency escape breathing apparatus a half mask 5 mounted near a visor part of a hood 1 engages the nose and mouth of the wearer so that the gases breathed by the wearer are inhaled from and exhaled to the interior of the half mask 5 and thence to a reservoir of breathable gas such as the interior of the hood 1 outside the half mask 5. Exhaled gases are regenerated by passage through potassium superoxide material 8 or 11 located either in the walls of the half mask 5 (Figs. 1 and 2) or in a container 10 mounted to the hood 1 near to the visor part of the hood 1 (Figs 3, 4 and 5). The potassium superoxide absorbs carbon dioxide in the presence of moisture and generates oxygen in proportion to the carbon dioxide absorbed. The gases pass through the potassium superoxide material 11 during both inhalation and exhalation (Figs 1, 2 and 3) or alternatively make a single passage through the potassium superoxide material 11 either on exhalation (Fig. 4) or inhalation (Fig. 5). <IMAGE>

Patent GB-2245504-A (GB)
Title: Apparatus for separating particulate material from a liquid
Inventor: BAGULEY WILLIAM
IPC: B01D35/26
Filed: 1991-06-27
Abstract: Particulate material, such as carbon or resin granules, are separated from a liquid, such as a slurry of ore from which the granules have adsorbed metal values, by pumping the mixture 20 up a pipe 12 and on to a frusto-conical screen 30. The liquid then passes through the screen to a collector 32, 34, and the granules flow down the screen, either back into tank 10 or into a second collector for recycling (Fig. 2). The pumping is effected by a rotary impeller 22 or by an air lift means 42, 44. Vanes 28 inhibit or allow limited rotation of the rising mixture, and baffle 40 directs it down on to the screen. The pipe 12 may have a wider portion at the top to reduce the flow velocity (Fig. 3). <IMAGE>

Title: Microwave and convection oven
Inventor: OVADIA AKA DAVID GILHESPY DAVI
IPC: H05B6/80
Filed: 1991-09-03
Abstract: A combined microwave and conventionally heated oven (gas or electric resistance) includes first and second chambers separated by a partition including first and second spaced panels 14, 15 which define a cavity 20 therebetween. These panels are metallic, except where the microwave waveguide passes through rectangular gaps in them, in which are situated rectangular, non-metallic, infrared-absorbing panels 27, 28. A microwave generator is provided in the second chamber to heat a product in the first chamber. A stream of cooling air reduces the temperature within the cavity in order to insulate the second chamber from the transfer of heat emitted from the first chamber in operation of the conventional heater(s). The infrared radiation absorbing panels at the end of the microwave waveguide permit the passage of microwaves from the microwave generator through the partition to the first chamber. Crisp food is produced by raising the air temperature of the oven to 260 to 400 centigrade within 25 seconds, maintaining that temperature for less than 3 seconds, reducing the air temperature to 160 to 250 centigrade and maintaining it whilst microwave heating the food. <IMAGE>

Title: Dual fuel low no x burner
Inventor: YANG SHYH-CHING
IPC: F23D17/00
Filed: 1991-12-30
Abstract: A burner for a furnace which is fuelled with gas fuel and oil fuel includes: a divergent quarl (6) merging with a wind pipe (2) housing a swirl generator (5); an annular hollow gas gun (2); an oil gun (3) received in the gas gun (2) and receiving a high pressure oil atomizing air tube (33) and where the gas jets (221) of the gas gun (2) and the oil jets (311) of the oil gun (3) have predetermined angles with respect to the centerline. Under designed operating conditions, a swirling air flow can be generated in the wind pipe with a low pressure drop and low turbulence, which is beneficial to flame stability, reducing flame temperature, and delaying the mixing of air and fuel, thus inhibiting the formation of NOx. Staging air from holes (7) in the quarl (6) and flue gas recirculation are available for further reduction of nitrogen oxides. The axial positions of the oil and gas guns are adjustable and the holes in the oil nozzle may be Y-shaped. <IMAGE>

Title: Measurement of the output of a lamp
Inventor: TAYLOR VERNON
IPC: G01J1/42
Filed: 1993-02-17
Abstract: The output of a lamp at P1 is measured by the use of a measuring mechanism comprising an array of sensors which may be moved through the beam B of light produced by the lamp. Means is provided for measuring the response of the sensors at successive distances longitudinally of the beam to produce output signals, which are modified to compensate for the different distances at which the response is measured. In this way the output of a lamp may be determined at relatively high speed, such as 30 to 50 kph, greatly reducing the time taken to check the quality of a linear array of lamps, e.g. bounding a runway or an airfield taxiway road. <IMAGE>
