Abstract: A heating device for mounting on an air inlet manifold of a compression ignition engine to heat the air flowing to the engine comprises a thin walled tubular element closed at one end and having a fuel inlet at the other end. A ceramic plug is located in the element to direct fuel flow against the interior surface of the element. A heating element is wound about the tubular element to heat and vaporize the fuel which flows out through an opening adjacent the one end. The fuel vapor forms an air/fuel mixture which is ignited by an ignition element.

Abstract: An inwardly opening fuel injection nozzle includes a first spring which is coupled by means of a push rod to the valve member of the nozzle. The nozzle includes a second spring positioned between the first spring and the valve member and acting upon a slidable abutment member which is engaged by the valve member after a predetermined movement of the valve member away from a seating. The valve member is lifted against the first spring by fuel under pressure supplied to an inlet to allow restricted fuel flow through an outlet and further against the action of both springs as the pressure at the inlet increases to allow unrestricted flow through the outlet.

Abstract: A fuel injection pumping apparatus for supplying fuel to a compression ignition engine has an annular cam ring which has internal cam lobes for imparting inward movement through cam followers respectively to pumping plungers mounted in a rotary distributor member. Stop rings are mounted alongside the cam ring to determine the maximum outward movement of the plungers. The stop rings are angularly adjustable to enable the maximum amount of fuel supplied to the engine to be varied. Two adjusting devices are provided the first being a piston which is subject to a fluid pressure varying with speed. The piston is biased by a spring and sets the stop rings to allow an excess of fuel for engine starting purposes and the second is a diaphragm assembly responsive to the air pressure in the engine inlet manifold.

Abstract: A multistage in-line rotary pump which comprises a closed pump body, a base element provided with suction and delivery connectors, and a head element. The pump body is surrounded by a cylindrical jacket or casing spaced from the pump body to form an annular return space, which casing is clamped between the base and head elements by means of stay bolts. Flat joints are provided between the base and head elements and the respective axial ends of the casing. To prevent high areal compression stresses in the area of the flat joints, the two extremities of the casing are plastically deformed to obtain a wall thickness which is greater than the wall thickness of the rest of the casing tube.

Abstract: The present invention relates to a device for detecting micro-leaks of gas by directing the infrared radiation created by a thermal gradient onto a wall, which device comprises an enclosure provided with an opening equipped with sealing means designed to be placed in contact with the wall, a sealed tank separated from said enclosure by a partition wall, said tank housing an infrared camera of which the objective is situated in front of a lens which is permeable to infrared radiations, means for sealingly applying the enclosure against the wall, means for creating a partial vacuum inside the enclosure, and an insulating screen placed in the center of the opening of the enclosure and applied against said wall in order to filtrate the gas leaks drawn in by the vacuum effect, to obtain a thermal gradient detectable by thermovision.

Abstract: A tepee tent using a combination of rigid and non-rigid tent poles to define a frame structure for supporting a truncated inner cover, the base of the tepee tent being defined by the shaped floor panel secured to ground by pegs, and an outer cover encompassing the frame structure and providing a spacing between the inner cover and the outer cover to improve ventilation therebetween. The outer cover is secured to the rigid tent poles by fasteners. The upper extremities of the rigid and non-rigid tent poles are commonly supported by an apex cup having sockets for securing the rigid tent poles and having hooks for supporting the non-rigid tent poles.

Abstract: Disclosed is an improvement of final cooling of the steel strip by immersing in cooling water, which strip has been cooled through a cooling zone in a continuous heat treating line. The improvement is achieved by injecting cooling water to the surface of the immersed strip to rapidly cool the strip to a predetermined temperature until the strip reaches the first sink-roll and resulted in that any dirt adhesion on the surface of the strip caused by contacting with the first sink-roll is prevented without increment of cooling cost.

Abstract: A fuel injection nozzle of the inwardly opening type includes a valve member which is biased into contact with a seating by a spring. The valve member is surrounded in part by a sleeve and both the valve member and sleeve are subject to fuel pressure so that axial forces are produced which act in opposition to the spring. When the forces are large enough the valve member and sleeve move but the sleeve movement and hence the movement of the valve member, is limited by a stop. Fuel is allowed to flow through an outlet at a restricted rate and only when the fuel pressure rises is the valve member moved further to allow unrestricted flow of fuel. The further movement of the valve member is limited by the engagement of an abutment on the valve member with the end of the sleeve.
