Patent DE-3840726-A1 (DE)
Title: Measuring method and measuring device for determining the diameter of a three-dimensional object
Inventor: ZIMMER KARL FRIEDRICH
IPC: G01B11/02
Filed: 1988-12-02
Abstract: With the aid of a common optoelectronic scanning device, on the one hand a bright/dark contrast image (contrast image in black-white transitions) generated by a back lighting (against-the-light) method is evaluated, and on the other hand a sharply focused light spot (batch) generated on the top side of the object by a focused light source is evaluated. The light beam generating the light spot is aligned at a prescribed angle in such a way that the reflected beam impinges on the scanning device inside the shaded region. The distance of the object from the scanning device is determined, in common with the width of the object, from the bright/dark (black-white) transitions.

Title: Land stabilisation and/or reclamation, preferably in the area of North Sea rigs
Inventor: HOELTER HEINZ DIPL ING
IPC: E02B3/18
Filed: 1988-12-19
Abstract: The invention relates to a method of land stabilisation and/or land reclamation by setting sheet-pile walls or the like in the bank area. In order to provide a method of this type, in which the effectiveness during the land stabilisation and/or reclamation can be considerably increased by the use of waste material which can otherwise only be used with difficulty, provision is made according to the invention for leach-resistant and stable plastic to be extracted from waste, shredded by means of pressure deformation and flushed with binding agents, such as, for example, natural sand, behind the sheet-pile walls or the like set beforehand, and for the plastic entwined in the process to serve as reinforcement. The plastic is advantageously flushed pneumatically or hydraulically from a flat-bottomed ship behind the sheet-pile walls or the like by means of naturally occurring sand.

Title: Short coupling device
Inventor: STOFFERS CLAUS-JUERGEN
IPC: B62D13/02
Filed: 1989-03-30
Abstract: In a short coupling device for a road train consisting of a lorry and a trailer, a guide rail which extends continuously a certain portion along each of the sides of the trailer is located in the region of the end wall of the trailer. The trailer drawbar fork engages via guide elements with the guide rail so that in the steering position the drawbar fork follows the course of the guide rail, the drawbar fork being secured to the live ring of the trailer in a longitudinally displaceable fashion. As a result, the distance between the trailer and the lorry is automatically increased when the steering is locked and automatically reduced when the degree of steering lock is decreased.

Title: Exhaust manifold for naturally aspirated engine - incorporates convergent outlet pipe which forms thrust nozzle
Inventor: LEISTRITZ HANS KARL DR
IPC: F02B1/04
Filed: 1989-04-11
Abstract: The naturally aspirated multi-cylinder piston engine has an exhaust manifold which can be formed in different designs as thrust nozzles. In this addition to the original system the part of the exhaust pipe (K1) which forms the thrust nozzle has a first part of progressively increasing dia.

The second part of the exhaust pipe (K1) has a progressively decreasing dia. (42).  The exhaust pipe is so curved over the part (K1) that the exhaust gas shock wave impinges on two surfaces (410;411) before reaching the straight part (52).

IPC: H01R13/627
Filed: 1989-05-24
Abstract: The invention relates to an electric plug and socket consisting of two connecting parts and having a locking device consisting of at least one engagement shoulder on the first connecting part and a holding device in the form of an angled rocker engaging behind the locking shoulder. The holding device has a securing tongue which forces it into its locked position. In the event of a rocking motion to put the device into the release position, support is provided on an abutment surface in the region of the peak of the angle of the locking device. To keep the mechanical load during the rocking motion as small as possible, it is proposed to make the abutment surface (36) convex and to arrange the peak of the angle (19) at a distance from the abutment surface (36), at least in the locking position.

Title: Inductive proximity switch with LC oscillation circuit - has second circuit coil adjacent to first one with mutual effect for specified attenuation
Inventor: SAGERT MANFRED
IPC: H03K17/95
Filed: 1989-06-19
Abstract: The circuit of an oscillator and a coil is supplied with A.C. The coil magnetic field actuates a measuring signal, compared with an external one for switching tripping.  By the coil, (2) of the first oscillation circuit lies the adjacent second coil (4) of a second oscillation circuit (4, 6, 7). The two circuits are so mutually affected, that the first circuit is largely attenuated by the second one, if the body (11) to be detected is absent. On the body pressure, the first circuit oscillator attenuation is removed such that the actuated oscillation can trigger switching course. USE/ADVANTAGE - For determination of a path, and/or position, and/or material properties of a body, with reduced attenuation factor and increased response sensitivity.

Title: Using waste from sugar beet - by processing to desulphurise chimney gas giving prod. suitable as improver for acidified soil
Inventor: HOELTER HEINZ DIPL ING
IPC: B09B3/00
Filed: 1989-07-07
Abstract: Utilisation of wastes from sugar prodn. from beet comprises contacting the waste, under spray conditions, with chimney gas of a combustion plant, then using the prod. for soil improvement of growth media. Treatment with the chimney gas is carried out under conditions which (1) do not destroy the humus characteristics of the waste and (2) do not cause significiant oxidn. (sic) of lime to gypsum, and the 'over-alkalinity' is not reduced to an extent which makes the material unsuitable as neutralising agent for acid soils. USE/ADVANTAGE - The treatment removes SO2 (and other acidic pollutants) from the gas and simultaneously lowers the pH of the waste material, making it suitable for neutralising lightly over-acidified soils. The temp. of the gas is not significantly reduced (contrast conventional wet washing procedures), eliminating the need for reheating.

IPC: E04F15/024
Filed: 1989-09-07
Abstract: A carrying plate is proposed, in which a building plate 1 is provided with a multiplicity of hollow-foot shells 2, each possessing a cup piece 5 displaceable in a sleeve piece 4. In this arrangement, it is desired that the hollow-foot shells of the carrying plate can be preset inexpensively at a given installation height and the carrying plate rests, in the mounted state, on preset hollow-foot shells, and that adaptation to floor unevennesses takes place by fine adjustment of the length of hollow-foot shells. This is achieved in that, for fixing the cup pieces 5 on the sleeve piece 4, in each case a radially interlocking bar device 8 is provided and in that, in the mounted state of the carrying plate, some of the hollow-foot shells 2 are barred in interlocking manner with respect to the rough installation height, whereas with the other hollow-feet shells it is possible to carry out a fine lengthwise alteration of the bar device 8. The mounted carrying plate is firmly supported firstly by some hollow-foot shells for walking on, and the other hollow-foot shells are altered finely, when the carrying plate is mounted, for the purpose of compensating floor unevennesses. <IMAGE>

Patent DE-4014516-A1 (DE)
Inventor: GOECKLER HEINZ DR ING
IPC: G01C19/72
Filed: 1990-05-07
Abstract: The aim of invention is to enable the amplitudes of selected spectral lines in the output signal from a ring interferometer to be determined simply and with the greatest possible accuracy. This is done as follows. A dividing network (FW) splits the digitized output signal from the ring interferometer into a first part-signal (s1), which contains the spectral lines with the odd multiples of the phase-modulation frequency, and a second part-signal (s2), which contains the spectral lines with the even multiples of the phase-modulation frequency. For each of these part-signals (s1, s2), there is at least one digital filter (F1, F2) which filters the spectral lines out of the corresponding part-signals (s1, s2) in order to determine their amplitude (A1, A2, A3, A4).
