Title: Percussion apparatus
Inventor: BUCK MANFRED DIPL ING
IPC: B25C1/04
Filed: 1987-09-08
Abstract: A percussion apparatus (1), operated by a pressure medium, for fasteners (12) has a withdrawal valve (44) for the pressure medium and a percussion member (6), by which the valve (44) can be opened via the actuating pin (42). The percussion member (6) is accelerated by a spring (38) which is tensioned by a rearward movement of the percussion member (6). This movement is transmitted by a detent pawl (31) and an angle lever (28) from the trigger detent (22) to the percussion member (6). A roller (36) on an adjustable slide (35) causes the release of the detent pawl (31) and thus determines the percussive force of the apparatus. The percussive force can be set precisely with the aid of the slide (35). <IMAGE>

Patent DE-3806310-A1 (DE)
Title: Metering valve for a fuel injection system
Inventor: REICHLE MANFRED
IPC: F02M69/52
Filed: 1988-02-27
Abstract: In a known metering valve for a fuel injection system the ports were of stepped design in order to obtain the greatest possible maximum volumetric flows with at the same time little scattering in the case of relatively small volumetric flows. This leads to considerable manufacturing problems. The invention therefore proposes to divide a port (11) of stepped design into at least two individual ports (51) of simple geometric design. These individual ports (51) can be made with essentially greater precision than a port of stepped design, since if the individual ports (51) are made using erosion electrodes an essentially more uniform erosion is obtained than in the manufacture of a port of stepped design. The metering valve is preferably used in fuel injection systems in which there is a simultaneous requirement for high maximum volumetric flows and little scattering at low volumetric flows. <IMAGE>
Patent DE-3807277-A1 (DE)
Title: Blower
Inventor: LICHTBLAU LEO
IPC: F04D29/44
Filed: 1988-03-05
Abstract: High-pressure blowers with highly curved blades cannot be produced with axially opening pressure diecast shapes but rather only with radially opening pressure diecast shapes because of the overlapping of the blades. The object of the invention consists in providing a high-pressure blower which is favourable in terms of flow and noise and which can be produced with an axially drawable pressure diecast shape. Means of achieving this consists in a longitudinal division of the blower blades, the blade components not overlapping. The invention is suitable for all axial or diagonal blowers with overlapping blades. <IMAGE>

Patent DE-3825811-A1 (DE)
Title: Method and apparatus for the gradual, automatic driving of a pipe section through a through-bore
Inventor: PFEIFFER LUDWIG
IPC: E21D9/00
Filed: 1988-07-29
Abstract: The invention relates to a method and an apparatus for the gradual driving of a pipe section through an underground through-bore (7), in particular with an inaccessible cross-section. Up to now it has been necessary to drive the pipe section through the through-bore from a starting pit by means of hydraulic jacks or the like, for which purpose forces dependent upon the length of the pipe section have to be applied. In order to avoid this, the pipe section is subdivided according to the invention into a multiplicity of individual pipe elements (1a-1f) which in each case are coupled to one another in pairs by drive units (25a-25e). To drive the pipe section, the drive units are controlled step by step and one after the other in such a way that the individual pipe elements are in each case moved individually and one after the other by a preselected distance (a), this procedure being started with the first, leading pipe element (1a), then being continued with the following centre pipe elements (1b-1e) and being completed with the last, trailing pipe element (1f). These steps of the method are then repeated until the end of the through-bore is reached (Fig. 3a). <IMAGE>
