Abstract: An induction heater has an electrical conductor 40 extending along an axis B. At least one solid heating element 43 for contacting and transferring heat to a material to be heated extends radially from the axis B and is formed of electrically conductive and preferably ferromagnetic material. An alternating electric current is supplied to the electrical conductor 40 to induce an electric current in a closed loop defined by a surface layer of the or each heating element 43 to generate heat therein. Induced eddy currents are confined to a surface layer due to the skin effect. The radial and axial thickness of the heating elements 43 is greater than twice the skin depth of the electrically conductive material at the frequency of the alternating electric current. Preferably the heating element 43 is in the form of a screw arranged on the outside or inside of an electrically conductive heating member 42. <IMAGE>

Title: Fuel injection apparatus
Inventor: RICHARDSON JOHN STANLEY
IPC: F23R3/12
Filed: 1992-11-24
Abstract: A gas turbine engine fuel injection apparatus (10) comprises a fuel spray atomiser (12) which directs a fuel spray on to the radially inner surface of an annular flow deflector (20). The fuel flows in a film over the flow deflector (20) surface towards an annular lip (22) at the downstream end of the deflector (20). Swirling air flows are directed over the radially inner and outer surfaces of the flow deflector (20) so as to atomise the fuel as it leaves the annular lip (22). The fuel is evaporated in the swirling airflows and thoroughly mixed with the airflows in a mixing duct (14) before being discharged into a combustion chamber (11). The thorough mixing of the evaporated fuel and the airflows prior to combustion results in the production of reduced quantities of the oxide of nitrogen. The region 16 externally of the fuel injection apparatus is at high pressure and, air flows through inlets 17, 23, 26, 27, 36 which have swirl vanes to impart a swirling motion to the air. <IMAGE>

Title: Pressure measurement: dead weight piston device
Inventor: DELAJOUD PIERRE ROGER
IPC: G01L27/00
Filed: 1993-11-26
Abstract: A dead weight piston pressure measurement/calibration device includes a cylinder 32, (Fig. 1) and a dead weight piston assembly that includes a piston 30 rotatable and movable vertically in the cylinder, and a bell housing 10 supported by the piston and carrying a number of calibration weights 202. The weight of the dead weight piston assembly initially is supported by an elastic stop device 124. Gas from an external source 26 is rapidly forced into the cylinder until the dead weight piston assembly rises in an "elastic" zone defined by the elastic stop device. Such movement is sensed to "proportionally" reduce the rate of flow of gas and stabilize the position of the piston in a free-floating equilibrium condition, and actuate a drive mechanism that rotates the dead weight piston assembly and maintains the rotation rate in a defined range without producing any sustained vertical or radial displacement forces on the dead weight piston assembly. The drive mechanism comprises, Fig. 3A, an equilateral-triangular configuration of pulleys 16 carrying drive belts 18 which surround drive surface 10c of bell housing 10. When plate 20 is rotated, idler pulleys 20 urge belt 18B against surface 10c at three points to rotate the housing and piston. Alternately (Fig. 5, not shown), the piston is stationary and the cylinder rises and is rotated by a similar belt drive system. <IMAGE>

Title: Electronic printing with increased resolution
Inventor: PORTUS ROBERT TERENCE
IPC: B41J2/505
Filed: 1995-03-28
Abstract: A method of printing on an image carrier material (10) comprises forming, on a display (12) an image defined by a plurality of lines of pixels. The method further includes transmitting light from each of the pixels in a predetermined timing sequence in the form of image dots, moving an image carrier material, which is formed of a light sensitive material, relative to the display (12). The illuminated image dots impinge on the carrier material (10) and form the image thereon. The carrier material (10) is moved in such a direction relative to the display (12) as to increase the number of image dots formed on each line of the carrier material (10) in relation to the number of pixels in each line of the image display. This thereby increases the resolution of the printed image.
