Title: Busbar holder

IPC: H02G5/02
Filed: 1982-08-21
Abstract: Busbars (21) are installed with busbar holders (11) which engage behind and over the busbar foot (211). Since the busbars (21) work mechanically, frictional wear occurs in this case between the busbar foot (211) and the claws which engage over the busbar foot (211) and form a component of the busbar holder (11). In order to reduce the wear, the claws which engage over the busbar foot (211) are replaced by rotationally-moving rollers (217, 218) on which the busbar foot (211) is supported. <IMAGE>

Um gleichzeitig zwei aufeinander senkrechtstehende Geschwindigkeitskomponenten messen zu können, wird entweder mindestens eines der Teillichtbündel nach Passieren des Streuobjektes durch koaxial entgegengesetzt ausgerichtete optische Rückführung in sich selbst oder durch koaxial entgegengesetzt optische Rückführung zu einem der anderen Teillichtbündel nochmals auf das Streuobjekt eingestrahlt. Eine andere Möglichkeit besteht darin, ein weiteres Teillichtbündel durch eine zusätzliche Strahlteilung aus dem ursprünglichen Laserlichtbündel zu bilden und optisch koaxial und entgegengesetzt zurückzuführen.

Patent DE-3302293-A1 (DE)
Inventor: WALLENFANG GERD
IPC: F02D41/40
Filed: 1983-01-25
Abstract: A fuel injection system, especially for air-compressing, spontaneous ignition reciprocating piston internal combustion engines. At least one parameter which characterizes the injection process, such as beginning and duration of the injection, is adapted to be regulated by at least one electromagnetic control valve per cylinder unit which can be controlled by an electrically operating data processor as a function of characteristic operating parameters of the internal combustion engine. In order to compensate for transmission deviations of the electromagnetic control valves caused by wear and operation, the control pulses of the data processor are transmitted to each electromagnetic control valve via a suitable circuit in such a way that the control valve opens and/or closes with a constant time delay during each control procedure. The constant time delay of the control valve can be established as a function of the actual speed of the internal combustion engine. The control time point of the control valve, as determined by the data processor, for opening and/or closing the control valve can be varied as a function of the constant time delay thereof.

Title: Process and apparatus for the combustion of solid fuels, preferably coal, in pulverised form
Inventor: SKOOG KURT
IPC: F23C7/00
Filed: 1983-03-18
Abstract: The coal is mixed with a carrier liquid such as water and/or oil, thus forming an emulsion, and for this purpose the fuel emulsion is sprayed through an approximately annular inlet opening (10) into a combustion chamber (22), so that a flow profile approximately like a hollow cone arises. A reduced pressure (region 60) is built up within this flow profile, directly behind the fuel emulsion inlet opening (10) which opens into the combustion chamber (22), so that a portion of the hot combustion gases and a residue of unburnt fuel particles are recirculated (64) to the inlet opening. Moreover, gas inlet openings (12,14,16,18,20), through which gas or air flows out, are provided in the end (42) of the combustion chamber (22), with their flow path running helically and concentrically with the axis (40) of the inlet opening (10) which opens into the combustion chamber (22) for the fuel emulsion. Thus the fuel emulsion sprayed into the combustion chamber (22) undergoes a rotational motion, so that the flow profile like a hollow cone undergoes a strong fanning out or broadening out into a bell-shaped or apple-shaped profile (66). By the stated measures, an extremely long particle path (68) on the shortest length along the mid-axis (40) of the combustion chamber can be ... Original abstract incomplete. <IMAGE>

Patent DE-3324803-A1 (DE)
Title: Dust precipitation device
IPC: B03C3/011
Filed: 1983-07-09
Abstract: The invention relates to a dust precipitation device which essentially consists of a tubular chamber with an electrode conducting high voltage arranged within it. In such industrial dust separator devices, collision ionisation of the supplied gases occurs, which leads to a charging of the entrained dust particles and their deposition on the inner wall of the chamber. To make such a dust precipitation device suitable also for sampling purposes, for which it must be transported, the precipitation process within the chamber is practically embodied in two stages, in that the electrode is divided in a length ratio of about 1:2 into a first section, as thin as possible, and a second section, at least 10 times thicker, with a high voltage supply of only 20 kV, the first section producing an electric field sufficient for collision ionisation and the second section producing an electric field sufficient for electrostatic separation. The small high voltage permits a limitation of the cost for the insulation, so that the device can even be carried by hand. Moreover the formation of ozone and oxides of nitrogen is so far reduced, in contrast to that at the otherwise necessary high voltage for dust separation, that injury to the health of the operating personnel is avoided.
Patent DE-3325148-A1 (DE)
Title: Magnetic field sensor
Inventor: POPOVIC RADIVOJE
IPC: G01R33/06
Filed: 1983-07-12
Abstract: The magnetic field sensor consists of an annular lateral bipolar transistor which is arranged on the surface in a semiconductor body (1). It is composed of a first circular inner semiconductor layer (3) as ohmic contact for the base connection, a second annular centre semiconductor layer (4) as emitter, a third annular outer semiconductor layer (5) as collector and a multiplicity of small rectangular semiconductor layers (6) arranged outside the external semiconductor layer (5). The part (8) of the semiconductor body (1) which is located between the centre and the outer semiconductor layer (4; 5) forms the base of the transistor and, in one variant of the magnetic field sensor, is covered with a gate (9) which is separated by a gate oxide layer (10) from the semiconductor body (1). The gate (9) consists, for example, of low-resistance material and is subdivided into the same number of mutually insulated ring sectors as there are rectangular semiconductor layers (6) in the magnetic field sensor. These latter semiconductor layers (6) operate as sensors and determine the position of an angularly limited charge carrier region in the transistor. The charge carrier region in the transistor rotates around the common axis of the annular or circular semiconductor layers (3; 4; 5) under the influence of a magnetic field acting perpendicularly with respect to the surface of the semiconductor body. <IMAGE>
