Title: Holographic measuring device
Inventor: ROTTENKOLBER HANS DR
IPC: G03H1/04
Filed: 1987-06-16
Abstract: A holographic measuring device has a holographic plate, on which the light which impinges from at least one reference beam is superimposed with the light, which is retroreflected from an object to be measured, of a coherent object illumination beam which is directed onto the object to be measured. For ease of handling and for use, independently of holography laboratories, as a modular mobile holography measuring head, the measuring device is designed with a holding plate which is stiff in terms of form and on which the holographic plate and outcoupling (output) holders, which have outcoupling optics, are attached for optical waveguides, which in each case transport the object-illuminating beam and at least one reference beam. The optical axes of the outcoupling optics for each reference beam are in each case located on the outer surface of a cone which extends with its vertex in the region of the holographic plate, and together with the middle axis of the cone in each case enclose an identical angle in the region of approximately 25@ to approximately 27@.

Patent DE-3721172-A1 (DE)
Title: Adjustable anti-warping means
Inventor: WAGNER BODO
IPC: E04F21/00
Filed: 1987-06-26
Abstract: The adjustable anti-warping means, which, in particular, is not, however, exclusively usable for doors and windows, exhibits an adjusting element, preferably in the form of a tension and/or push rod, which is fastened on two spaced-apart fastening elements fitted on the object which is to be secured against warping, it being possible to change the length of the adjusting element. Said anti-warping means permits the correction, compensation and alignment of warped objects, such as doors or windows, in a simple manner, with the result that, in the production of doors and windows, a warpage-preventing type of construction no longer has to be terribly important and steel frames no longer have to be used for mechanical stability.

By opening individual valve paths or by the combined opening of the valve paths, seven different volumes for the discharge out of the supply container (1) can be released by this means, when the magnetic valve (15) is opened. The metering device is suitable for dishwashing machines and washing machines having water softening devices. <IMAGE>
Patent DE-3829779-A1 (DE)
Title: Process for removing organic chlorine compounds from a fluid to be purified
Inventor: KREIN HANS-JUERGEN
IPC: A62D3/34
Filed: 1988-09-02
Abstract: In a process for removing organic chlorine compounds from a fluid to be purified, in particular from mineral oil, the fluid to be purified is contacted with a chemical purification substance which reacts with the chlorine of the organic chlorine compound in a purification reaction to give a reaction product which is solid in the fluid, and the reaction product is precipitated. The purification substance used is a hydride from the group comprising "metal hydrides, alkali metal hydrides, alkaline earth metal hydrides, or in the form of mixed hydrides or complex hydrides" or mixtures thereof. This takes place in such a way that the bonding locations being freed during the purification reaction on the molecules of the organic chlorine compounds by released chlorine atoms are occupied by hydrogen. As a result, interfering reactions of residual molecules from the (degraded) organic chlorine compounds are suppressed in the purified fluid.

Title: Side-inclination adjustment of a driver's seat (for example for tractors, construction machinery) by a suspended seat (swinging system)
Inventor: WOLL HELMUT
IPC: B60N2/50
Filed: 1989-02-22
Abstract: The suspended seat shell is always brought into the vertical position by the driver's weight. Conventional seats without means for compensating for travel on slopes are always at right angles to the vehicle. Hence the driver always has the edge for a vertical posture, curvature of the spine inevitably occurs when travelling on slopes. The "swinging seat" adjusts automatically to the natural, vertical posture on account of the weight of the driver.
