Title: Fuel Injector with Insulating Air Cavity and Means to Prevent Fuel Entry
Inventor: HALL TROY
IPC: F23D11/10
Filed: 2009-06-15
Abstract: A fuel injector 100 has a nozzle body with an internal air path, an insulating gap 124 between a radially inner wall 120 and a radially outer wall 122 of the nozzle body, and an inhibitor ring 128 at a downstream end of the nozzle body. The inner wall and the outer wall are able to move relative to one another, and a first interface 126 between the inner and outer walls provides resistance to the flow of fuel entering the insulating gap. The first interface is formed between the inhibitor ring and the nozzle body, and a second interface 130 can be formed between a downstream end of the inner wall and an upstream end of the inhibitor ring to further accommodate relative axial movement of the inner and outer wall. The inner wall can be a heat shield, and the fuel injector can include inner and outer swirlers 118, 116, and be configured as an air-blast fuel injector. Alternatively, the second interface can be omitted, and the air-blast fuel injector can include a fuel passage 114 with an associated fuel swirler and downstream spin chamber. The inhibitor ring can be a brazed or welded insert, or an integral part of the outer wall.

Inventor: ROBERTSON DUNCAN PAUL
IPC: A47F8/00
Filed: 2009-09-15
Abstract: Images of foreground objects 101a, 110 in a scene are generated by causing electromagnetic radiation to be emitted having a first spectral power distribution from a surface of a first foreground object 101a, which is adjacent or at least partially obscured by a second foreground object 110. A first image of both of the first and second foreground objects is acquired whilst the first foreground object emits electromagnetic radiation with the first spectral power distribution. A second image of the first and second foreground objects is acquired whilst the first foreground object is not emitting electromagnetic radiation or is emitting electromagnetic radiation with a second spectral power distribution which is different to the first spectral power distribution. An alpha matte of the first and second foreground objects is generated based on a comparison of the first image and second image.

Abstract: 541,792. Refrigerating. HOOVER, Ltd. June 10, 1940, No. 10121. Convention date, July 8, 1939. [Class 29] Absorption systems.-Circulation of liquor between the generator B, Fig. 1, and absorber A of a continuous cycle inert gas system is effected by placing a reservoir K alternately under the suction and discharge pressure of the inert gas circulating fan F. The ends of pipes K<2>, K<3> communicating with the suction and delivery of the fan are closed alternately by a valve L<1> actuated through a snap-action spring by a float M. Liquid flows from the boiler to the reservoir while the latter is under low pressure until the valve is moved by the float to establish high pressure, when the liquid is delivered to the absorber. Check valves may be placed in the liquor conduits. A gas pressure pipe N<2> leads from the reservoir to a condensate receiver N, and liquid is fed under pressure to the evaporator E, so that the condenser C need not be higher than the evaporator, which may operate as described in Specification 504,374. In another arrangement, Figs. 5 and 6, reservoirs X<1>, W<1>, preferably formed as semi-cylindrical compartments of a single vessel, are put alternately into communication with the fan suction and delivery by a rotary valve Y moved by a slotted link Z<3> and a snap-action spring Z<2> from a pivoted float Z. In a further arrangement, (Fig. 4, not shown), a fluctuating pressure is applied to the generator through the condenser by means of valves in the inert gas conduits which are actuated by electromagnets controlled by a timing device. The disposition of the apparatus with respect to a refrigerating cabinet is described, in which the generator and absorber are below and the condenser behind the storage space in an air flue, with the refrigerant receiver within the insulation of the removable back panel carrying the evaporator.

Abstract: 514,775. Photo-electric telephone metering equipment. STANDARD TELEPHONES & CABLES, Ltd. (Schreiber, L. J. J.). April 6. 1938, No. 10562. [Class 40 (iv)] [Also in Groups XL and XIX] A telephone subscriber's meter is provided with code markings of numerical values for photo-electric scanning directly or from photographs thereof. The code markings for the several numerals of each digit are formed on a wheel 50, Fig. 7 or band 9, Fig. 2, which takes the place of the usual digit wheel. Various codes may be used in one or two columns and moving in various ways. For example, a single row of light and dark spots moving the space of one spot at a time and visible four spots at a time giving the code indicated by Fig. 4; or a single row, Fig. 9, movable two spots at a time and visible four spots at a time giving the code indicated by Fig. 8; or a double row of oppositely-inclined facets 68, Fig. 13, four facets (two in each row) being exposed at one time to reflect light to one or more of four cells 73. Each meter is also provided with a mirror and a.spot for controlling the photographing and scanning devices, and with the subscriber's number, which may be in four-element code. In the photographing equipment, Fig. 1, a carriage 2, is moved horizontally by a screw or rack gear driven by a motor 6 so as to be brought in succession opposite every meter in a line in a rack 1, then a motor 7 operates to shift the carriage to the next line of meters and the motor 6 again operates' to shift the carriage one meter at a time along the second line either in the opposite direction or in the same direction, in which latter case a quick idle reverse of the carriage intervenes. The carriage supports a lamp 17, Fig. 5, for illuminating the meter and throwing a beam through a lens 181 on the control mirror 15 of the meter. The reflection from the mirror 15 is adapted to strike a photoelectric cell 20 on the carriage to control the step-by-step movements of the carriage. While the carriage is at rest in front of each meter a photograph of it is taken by a camera 18 under control derived from the cell 20, and while the carriage is moving to the next meter, the film 22 is unrolled one step. A system of relays controlled by the output of an amplifier connected .to the cell 20 is provided to control the several operations. The photograph taken at each meter includes all the data of the meter and also the control spot 16<SP>1</SP> of an adjacent meter. In another arrangement, scanning devices are carried by the carriage 2, Fig. 1, instead of the camera 18, Fig. 2. In this case, the meter is "restored" after each scanning, and a miniature camera may be provided to take photographs of the meter readings to be kept on record in case of disagreement by subscribers. The scanning may be performed by a movable cell or by a bank of cells.
