Patent DE-3619990-A1 (DE)
Title: Piston pressure accumulator
Inventor: ZIRPS WILHELM
IPC: F16J15/16
Filed: 1986-06-13
Abstract: The piston pressure accumulator has a piston (12) which divides a gas space (13) from a liquid space (14). The piston is prestressed by compression springs (18 to 20) arranged in the gas space (13). A combination of seals (25, 29; 32, 33) is arranged on its outer circumference and ensures that gas cannot penetrate out of the gas space along the outside of the piston and into the fluid space (14). As a result, the service life of the piston pressure accumulator is increased. <IMAGE>

Title: Device for metering ink on printing machines
Inventor: JENTZSCH ARNDT DIPL ING
IPC: B41F31/20
Filed: 1987-08-07
Abstract: The invention relates to a device for metering ink. The aim of the invention is to eliminate the interferences during metering of the ink which reduce the printing quality. The object consists in reducing the hydrodynamic effects of force and thus the deformations in the metering region, improving the adherence of the ink to the ink ductor and eliminating the particles of dirt which have entered the metering region. According to the invention, this is achieved in that the ink ductor which is provided with a profiled outer surface and rotates constantly at a slow speed is assigned a cutting roller which rotates at the speed of the cylinder. Between the outer surfaces of the ink ductor and the cutting roller there is a gap "s" which is equal to or smaller than the smallest adjustable gap "dmin" between the leading edge of the ductor knife and the ink ductor. <IMAGE>

Title: Method for cutting concrete parts, in particular concrete pipes, preferably with a large clear diameter and device for implementing the method
Inventor: KRAISS RICHARD
IPC: B23D45/12
Filed: 1988-01-29
Abstract: A method for cutting concrete parts, in particular concrete pipes, preferably with a large clear diameter, is proposed, which makes possible extensively automatable cutting through of concrete pipes at any cutting angle to the pipe axis and at the same time achieves reliable plane cut surfaces. To this end, the pipe is first aligned in such a manner that the pipe axis and the cutting plane of the cutting tool enclose an angle with one another which corresponds to the desired cutting angle, and is then clamped securely in this alignment. The securely clamped pipe and/or the cutting tool are driven relative to one another rotationally about an axis of rotation at right angles to the cutting plane and translationally in such a manner that the cutting tool is guided repeatedly over the circumference of the pipe and at the same time carries out a feed motion which exceeds the wall thickness of the pipe. A device for the automatic implementation of this method is indicated.

Title: Method for one-sided processing of bodies of planar extent, in particular of semiconductor wafers, and device for carrying out the method
Inventor: FLOEDL HELMUT DIPL ING
IPC: C23F1/08
Filed: 1988-03-31
Abstract: The invention relates to a method for one-sided processing of bodies of planar extent, in particular of semiconductor wafers, as well as a device for carrying out the method. According to the invention, the body to be processed is immersed in a liquid medium, for example an etchant. In order to displace the liquid medium from the lateral surface of the body which is not to be processed, a gaseous medium is led into a narrow gap, which adjoins via the lateral surface of the body which is not to be processed, and is led over this lateral surface in such a way that the direction of flow of the gaseous medium is outwards in the radial direction from the centre of the body to the rim thereof. The result is a simple and cost-effective single-sided processing of a body, since masking of the side of the body which is not to be processed is eliminated.

Title: Telescopic sight having cross-lines grid
Inventor: GOUBEAUD KARL-HEINZ
IPC: G02B27/36
Filed: 1988-07-16
Abstract: In a telescopic sight of the monocular, mono-objective type a cross-lines grid is fastened in an intermediate plane, which grid carries at least one line pattern with scale division. When looking through the telescopic sight, the position of the cross-lines grid can be changed relatively by means of the knobs for the range and azimuth drive without it being necessary for this purpose to change the effective position of the cross-lines grid with respect to the telescopic sight housing. In the intermediate image plane of the cross-lines grid or in another plane a pin projects inside the telescopic sight. This pin is held by a holding screw in an adjusting device of two rotatable eccentric O-rings, plugged inside one another, which adjusting device can be defined. As a result of this fastening of the pin, this pin can change its position in a limited region. Since, when during an adjustment by means of the buttons of the range and azimuth drive the pin is moved over a limited region of the cross-lines grid when the telescopic sight is looked through, the pin can serve as pointer for a line pattern which is located on the cross-lines grid in this region and has a scale division and can thus make visible on the cross-lines grid the adjustment by means of the buttons of the range and azimuth drive when the telescopic sight is looked through. <IMAGE>
