Abstract: A combustion chamber arrangement in a direct injection type diesel engine, having a cavity (6) at the top of a reciprocating piston (2) to form a combustion chamber (4), and a fuel injection unit for injecting the fuel toward the cavity. A part of the inner circumfer­ential wall of the cavity (6) is formed in a concave arc shape and constitutes a concave fuel reflecting surface (7b). The concave fuel reflecting surface (7b) is such that the injected fuel is reflected at the concave fuel reflecting surface (7b) and the course of the reflected fuel (G) is shifted continuously from the peripheral region of the cavity toward the central region of the cavity during the upward movement of the piston, to thereby causing a burning flame to propagate from the peripheral region of the cavity toward the central region of the cavity.

Title: Method and device for counting flat objects arriving in overlapping fashion, such as sheets, periodicals and the like
Inventor: DUSS HANSPETER
IPC: G06M7/00
Filed: 1989-08-21
Abstract: Flat objects, such as printed sheets, periodicals and newspapers arrive in overlapping formation (6, 6<'>). In order to count the objects continuously, the overlapping formation (6, 6<'>) is moved along a conveyer plane (3) through the active region of an ultrasonic transmitter (7). Two ultrasonic receivers (7<'>, 15) for receiving the echo waves are directed counter to the active region of the conveyor plane (3) in two directions at an angle to one another. The echo signals of the receivers (7<'>, 15) are fed to a data evaluation unit (14) via a control unit (13). The data evaluation unit (14) contains counting and computing means in order to sense the timing and the size of successive echo signals of the receivers (7<'>, 15), to compare them and to process them. As a result, a reliable counting of the individual objects in the overlapping formation (6, 6<'>) is obtained independently of the prevailing illumination and reflection conditions and independently of the state of the overlapping formation (6, 6<'>).
