Patent DE-4109256-A1 (DE)
Inventor: HALLAS ERNST DR
IPC: G02F1/33
Filed: 1991-03-21
Abstract: The invention relates to a device for deflecting a light beam by diffraction on an optical grating. Such deflection of a light beam is necessary in optical measuring instruments, for example gas or liquid analysers. These require, in particular, a variable deflection, e.g. a circular deflection; i.e. the deflected beam describes a circular path. The latter is achieved in known devices with the aid of mechanically moved, optical arrangements, but these have disadvantages in respect of wear and cost. A device according to the invention results in a circular deflection of a light beam by diffraction of the light beam on a rotating optical grating. The optical grating is realised here by the density differences in a preferably liquid medium which is situated in a cylindrical vessel. The density differences are caused by ultrasonic vibrations and generated with the aid of ultrasonic transmitters which are mounted on the circumferential surface of the cylindrical vessel. The rotating optical grating is produced by sequential triggering of the ultrasonic transmitters. <IMAGE>

Inventor: NOLTE ALBERT
IPC: F02F7/00
Filed: 1991-11-21
Abstract: 2.1 A known internal combustion engine has an injection pump element which is of inherently rigid design. Proceeding from this it is proposed to increase the rigidity of the injection device as a whole.   2.2 According to the invention this is achieved in that the camshaft 2 is driven by way of a single tooth engagement of the crankshaft, that the injection pump element 15 is arranged in the area of the assigned cylinder 9 in the crankcase 9 and is oriented towards the cylinder head 11, and that the high pressure outlet 20 of the injection pump element 15 is adjacent to the injection valve 13 on the shortest path. As a result the injection line 21 can be designed very short. All in all a very rigid injection device is thereby created with the resulting advantages. <IMAGE>
