Title: Device for controlling the phase angle between interference signals
Inventor: BUECHNER HANS DR ING
IPC: G01B9/02
Filed: 1986-01-23
Abstract: The invention relates to a device for controlling the phase angle between interference signals in optical interference precision measuring instruments. The aim of the invention is to avoid measurement errors due to changes in phase angle resulting from environmental influences, and to reduce the outlay on adjustment of the photoelectric receivers. In order to achieve this aim, an optical phase shifter consisting of a pair (4, 6) of glass wedges and a piezoelectric element (5) is arranged in the interferometer beam path. The interference signals obtained are fed to a special phase meter (11) which delivers a voltage which is dependent on phase angle and independent of the instantaneous direction of motion of the interference fringes. A connected controller (19) controls the optical phase shifter (4, 5, 6). <IMAGE>

Title: Drill hole closure with double inflation ring seal
Inventor: BRUEGMANN DIRK-ALEXANDER
IPC: E21B33/128
Filed: 1986-05-21
Abstract: A drill hole closure which can be clamped into the drill hole at any desired point has a closure element which consists of the valve head with the valve and a clamping sleeve which is detachably connected to the charging pipe. Both parts are connected to one another in a displaceable fashion by means of a clamping anchor, inflation rings and a securing ring being arranged between them. The securing ring is connected in a positively engaging fashion to the protection pipe which surrounds the charging pipe so that, by turning the charging pipe, the clamping sleeve can be effectively pushed on the clamping anchor against the valve head without a counterbearing being required for this clamping process. During the displacement of the clamping sleeve on the clamping anchor against the valve head, the intermediatly mounted inflation rings are deformed in such a way that they bear in a sealed fashion against the wall of the drill hole. <IMAGE>

Patent DE-3619486-A1 (DE)
Title: Machine-controlled welding tongs
Inventor: SVOJANOVSKY RUDOLF
IPC: B23K11/31
Filed: 1986-06-10
Abstract: Machine-controlled welding tongs. It is characterised in that in the force transmission path between the arms (2, 4) of the tongs and the connection element (34) of a tongs carrier a switch-off safety device (52) is arranged between the connection element (34) and the arms (2, 4) of the tongs, and in that a transformer (38) is arranged between the connection element (34) and switch-off safety device (52). As a result, a reduction in the weight to be carried by the switch-off safety device is achieved, which leads to finer setting of the switch-off securing element and thus to more reliable signalling in the case of an undesired collision. The danger of damage to the components and/or to the tongs carrier (robot) is thus substantially reduced. <IMAGE>

Patent DE-3629426-A1 (DE)
Title: Storm-guard for motor vehicles
Inventor: BURGER MANFRED R
IPC: B60J11/00
Filed: 1986-08-29
Abstract: The storm-guard for motor vehicles comprises a protective covering (1) which is formed preferably by two plastic sheets (10, 11), placed in an exactly fitting manner one above the other and bonded to each other at the sides, in which protective covering the sheets are moreover bonded to each other in certain parallel tracks or in a meander-shaped track so that a multiplicity of air chambers (15) is formed if air is blown via a valve (17) into the gap between the sheets (10 and 11). Skirts (4a, 4b) attached at the sides protect the sides and increase the stability against the effects of wind when the protective covering (1) is stretched over the top side of a motor vehicle with the aid of extendable attachment elements (6a, 6b, 7a, 7b). The protective covering can be produced economically, folded up and stowed in a small space and if the need arises, for instance if hail is imminent, can very quickly be stretched over a motor vehicle and also very quickly inflated, for example using the spare tyre. In another solution variant the protective covering is stretched over the motor-vehicle body at a certain distance therefrom using a supporting device. <IMAGE>

Patent DE-3708702-A1 (DE)
Inventor: HOFFMANN HEINZ-RAINER DIPL ING
IPC: B62D21/18
Filed: 1987-03-18
Abstract: Agricultural tipping trailers should have a chassis frame of low torsional rigidity when running off the road whereas, when tipping, particularly about a tipping axis transverse to the longitudinal direction, they should have a torsionally rigid chassis frame. Fitting a torsion element with a clutch inside the chassis frame, by operating which either a torsionally rigid chassis frame or one of low torsional rigidity can be set, is known in the art. According to the invention, automatic setting of the desired torsion characteristic of the chassis frame (1) is achieved in a particularly simple manner in that the switching operation for the rigid coupling of a torsion tube (8) to a cross member (12) against the force of a spring (39) is derived directly from the control variable formed by the deflection movement of a lifting cylinder (15). The coupling of the torsion tube (8) is likewise automatically released by the spring (39) on completion of the tipping process and relieving of the load on the lifting cylinder (15). For a chassis frame (1) of this type, on which torsion characteristics are automatically set according to the operating state, no complex control devices are required and in particular practically any conventional chassis frame can be easily converted in this way at little cost. <IMAGE>

Title: Variably adjustable attenuator
Inventor: SIGLOCH FERDINAND DIPL ING
IPC: H03H7/25
Filed: 1987-03-18
Abstract: For a variably adjustable attenuator having PIN diodes arranged in a T circuit, a largely constant standing wave ratio which is low over the entire range of attenuation can be achieved in that a control current for the series elements and a control current for the shunt elements is generated from a common control signal via two function generators, the first control current for the series diodes falling exponentially and the control current for the shunt diodes increasing exponentially with increasing attenuation. A preferred circuit for the function generators and a configuration of such an attenuator which is distinguished by particularly low interference due to crosstalk and intermodulation are specified.
