Title: Pressure control valve
Inventor: SCHLOTT WALTER ING GRAD
IPC: F02M69/38
Filed: 1982-09-08
Abstract: A pressure control valve (42) is proposed which serves as a component of a fuel injection system for influencing the fuel/air mixture of an internal combustion engine. The pressure control valve (42) has a movable valve component (45) on which a spring force (46) engages in the closing direction with respect to a fixed valve seat (44) and can be influenced by a bimetal spring (50) with a rectangular cross-section. The bimetal spring (50) can be heated by an electrical heating element (53) which is placed on it and has a coil carrier element (58) and a coil winding (59) which is covered by a cover layer (66) having mineral components. The cover layer is to be of the thinnest possible construction in order to achieve the most uniform possible heating up speed of the bimetal spring (50). The coil carrier element (58) is provided with a central passage opening (60) through which the bimetal spring (50) projects. The heating element (53) on the bimetal spring (50) is fixed via bumps (62) on at least one broad side (61) and bumps (not illustrated) on the narrow sides of the bimetal spring. As a result, a precise transmission of heat, which ensures that heating-up speeds of the bimetal elements remain uniform even in series production, is guaranteed. <IMAGE>

Title: Supporting and running roller device for sliding doors
Inventor: WENZEL HOLGER DIPL ING
IPC: E05D15/06
Filed: 1983-03-12
Abstract: The supporting and running roller of a sliding-door element, in particular a shower partition, is mounted vertically adjustably on the element by means of an eccentric disc, so that the sliding-door element can be aligned. Adjustment takes place solely by the rotation of the eccentric disc, and a catch retention which can jump over during the adjustment guarantees that the setting finally obtained is preserved during the subsequent use of the sliding door. One of the two catch elements belonging to the catch retention consists of at least one resilient arm which engages with its toothed portion into a corresponding catch toothing which engages on the circumference of the constructional part having the eccentric disc. Preferably, on both sides of the axis of adjustment of the eccentric disc there are arms which are in one piece with the roller holder to be mounted releasably on the sliding door and which have the desired spring property centrally because they are clamped at the ends. The arms are equipped there with the toothing which engages mirror-symmetrically to the axis of adjustment into the continuous circumferential toothing of a flanged disc in one piece with the eccentric disc. The flanged disc also contains the recess for the adjusting tool.

Title: Method for the active enhancement of the tip reflection of puncturing needles on imaging by echo sonography, as well as a device for carrying out the method
Inventor: EINIGHAMMER HANS J DR
IPC: A61B90/00
Filed: 1983-03-31
Abstract: On echo sonographic imaging by means of the invention the echos of needle tips on the screen are much brighter than is possible by means of "passive" measures for improvement of the scatter effect of the tips by appropriate shaping or the like. This is achieved with an additional device on the scanner by recording of the wire wave pulses which are coupled into the tip and by the subsequent generation of either (a) intensified wire pulses which emerge from the tip as longitudinal wave pulses and are superimposed on the normal scatter wave or (b) intensified electrical pulses which are directly admixed with the image signal. The time of active pulse emission is automatically determined electronically in each case.

Patent DE-3313379-A1 (DE)
Title: Projection system
Inventor: SYLLA JUERGEN DIPL ING
IPC: G02B5/08
Filed: 1983-04-13
Abstract: In a projection system, in particular for a microfilm reader having a light source and a deflecting mirror, it is proposed to use a heat-absorbing glass as substrate (W) for the deflecting mirror, and to provide this glass with a reflective coating (SR) on the side averted from the light source. This produces the advantage that the heat-absorbing filter otherwise required is eliminated, and this leads to savings in material and space. A cost-effective aluminium or silver layer can be used as the reflective coating (SR), since it can be easily protected against chemical corrosion at the point provided in accordance with the invention. <IMAGE>

Patent DE-3405041-A1 (DE)
Title: Apparatus for the preheating of heating oil
IPC: F23K5/20
Filed: 1984-02-13
Abstract: Such apparatuses, in which the heating oil is preheated in the apparatus, when the burner valve is closed, in a closed circuit by means of a heat exchanger or an electrical heating body, have the disadvantage that after a long inoperative period, oil which has cooled in the nozzle connection is not heated during the heating-up of the oil circulated in a closed circuit, and hence the burner nozzle becomes sooty when the heating plant is set in operation. This can be prevented according to the invention in that the pressure acting on the burner nozzle, and hence also the throughput through the burner nozzle in the starting phase, is reduced, in that a relief valve (132) and a pressure-retaining valve (133) are arranged in a branch duct (13) which opens into the oil return duct (14) and forms a part of a closed preheating circuit. <IMAGE>

Title: Process and apparatus for producing monofilament nonwovens
Inventor: BEYREUTHER ROLAND DR SC TECHN
IPC: D04H3/16
Filed: 1984-05-26
Abstract: The practicability of the invention extends to the production of specifically fixed monofilament nonwovens which are primarily suitable for the technical sector. The object of the invention is to achieve a high tearing elongation of the monofilaments along with a low energy consumption, whilst the monofilament speed is to be brought significantly nearer to the air speed in the drawing-off channel as a result of an increase of the drawing-off forces. The solution according to the invention provides the supply of a diffuse air flow above the drawing-off channel, which is directed by a suction flow of corresponding air quantity which is generated underneath the delivery belt and which is propagated in the drawing-off channel. The large channel length possible thereby imparts to the monofilaments high drawing-off forces which are at a maximum at the point where the monofilaments have the temperature of the conclusion of the deformation-related imparting of orientation. The walls of the drawing-off channel have an inclination of 0 DEG </=  alpha  </= 3 DEG relative to the vertical. The diffuse air flow above the drawing-off channel is preferably supplied by way of a channel from the delivery side of the fan generating the suction flow underneath the delivery belt.
