Title: Method and system for fuel injection in internal combustion engines, particularly in diesel engines
IPC: F02M59/26
Filed: 1981-06-30
Abstract: The inlet port 38 through which fuel for pre-storage in the pump working chamber (18) is of constant cross-section Az and the inlet pressure Pz is electrically regulated by a device (32) to determine the quantity of fuel which is pre-stored. In addition, the instant of commencement of delivery is shifted in independence upon operating parameters by varying the return-flow quantity of fuel spilled through ports (23), and an unintentional shift in the instant of commencement of delivery upon a change in the quantity of fuel injected is avoided by simultaneous correction of the return-flow quantity of fuel. To shift or correct the instant of commencement of delivery, the angular position of the pump piston (15) is variable by an adjusting device (24) actuated by an electromechanical adjusting member (27). An electrical control device (39) generates a control pulse (IFB or IK) for the adjusting device (24) and a pressure-control pulse (Ipz) for the pressure regulating device (32).   <IMAGE>

Title: Method and apparatus for assessing the quality of cement clinker
Inventor: IRONMONGER CECIL THOMAS
IPC: G01N21/35
Filed: 1981-11-27
Abstract: The quality of cement clinker 11 is assessed with regard to its reflectance by using a photoelectric cell arrangement 10 which receives light from a pulsed infrared source 13 irradiating a bed of clinker transported on a conveyor-belt 12. The clinker quality is related to its colour (reflectance), which in turn is related to a high or low free calcium oxide content. Arrangements are disclosed to eliminate errors due to background illumination. To compensate for changes in optical path, due to changes in the height and disposition of the clinker bed on the conveyor, the field of illumination of the light source overlaps the field of view of the photoelectric cell arrangement by a predetermined amount. <IMAGE>

Title: Transmissions
Inventor: ARMSTRONG JOHN RICHARD CAREW
IPC: F16H1/00
Filed: 1982-10-21
Abstract: A rigidly supported gearbox casing (1) houses a gear train (6/7/8/9/10) that interconnects an input shaft (4) and an output shaft (5). A gear (8) of the gear train is supported for pivoting relative to other gears (6,9) of the train by a subsidiary shaft (12). Pivoting of the shaft (12) is compliantly restrained, externally of the casing (1), so that compliant restraint is introduced into the transmission of power from the input shaft (4) to the output shaft (5). Thus fluctuations in power supplied to the input shaft (4) can be reduced at the output shaft (5). By siting the compliant restraint mechanism externally of the casing (1) large angular displacements of the gear (8) associated therewith within the casing (1) are possible, design of the compliant restraint mechanism is unhampered by space or weight considerations, and there is good access to all components. <IMAGE>
