Title: Plugboard consisting of an insulating material board and electrically conductive sockets which are introduced into its recesses
Inventor: SCHARNAGEL JOSEF
IPC: H05K7/10
Filed: 1988-09-01
Abstract: A plugboard (1) consists of an insulating material board and electrically conductive sockets (insert parts, for example 48) which are introduced into its recesses (2), pass through the plugboard and are connected on a rear side of the insulating material board to conductor tracks. At least on a front side of the insulating material board, electrical connecting elements or electrical components can be inserted into the sockets. In order to design the circuit layout using such a plugboard to be compact, and to ensure reliable contact is made between the individual sockets, at least one contact spring set (49 or 51 respectively) is provided in each case in the open sockets on the front side (58) and on the rear side (59), adjacent to the front side and adjacent to the rear side, in order to provide the capability to fit the plugboard (1) on two sides. <IMAGE>

Title: Noise protection wall consisting of grid mats
Inventor: CZINKI LASZLO DR
IPC: E02D29/02
Filed: 1988-10-01
Abstract: Noise protection walls on motor highways and at industrial works, or else for suspended fixture, can be produced in an extremely short time and in substantially mechanised fashion since all of the grid mats of a grid cage are formed with a large area and with the same dimensions and each have on one mat side wire hooks, via which an articulated connection is or can be established with the next grid mat in each case. By means of appropriate grid mats, grid cages of virtually any shape and size can be produced, it being possible advantageously for a large grid cage formed in this way to be accessible to lorries and filled thereby, for example from one narrow side. This method of filling has the advantage of simplicity and the short erection time, but also, moreover, a considerably improved stability, the individual grid mats being connected by cross-struts which, owing to their hooks formed at the ends, can be simply attached to the opposite grid mats. <IMAGE>

Title: Interferometric force measuring device
Inventor: JAEGER GERD PROF DR SC TECHN
IPC: G01G3/12
Filed: 1989-01-28
Abstract: The invention is based on the object of providing a device for measuring small forces, which cannot be adversely affected by electromagnetic and electrical disturbing fields. According to the invention, the object is achieved in that a deformation body is used, which consists of a bending body and of an inflexible base body, and that a weighing beam is arranged on the bending body. Connected to the deformation body are the assemblies of an interferometer specially suited for being supplied with monochromatic radiation by means of optical waveguides and for scanning the interference phenomenon, likewise by means of optical waveguides. By means of suitable fastening of the assemblies on the deformation body, using distance rings, the influences as a result of temperature changes are eliminated. <IMAGE>
Patent DE-3904493-A1 (DE)
Inventor: MAGIN LUDWIG DIPL ING
IPC: B60K17/344
Filed: 1989-02-15
Abstract: 1. Driving device for at least two pairs of wheels. 2.1 Driving devices (14) for all-wheel drives on motor vehicles (10), particularly on agricultural tractors, commonly suffer from the disadvantage that, when cornering, distortion occurs throughout the drive train or balancing of the wheel speeds is permitted by means of differentials, freewheeling mechanisms or similar devices, which leads, however, to a loss of traction as soon as one of the wheels comes in contact with a non-adhering surface. 2.2 It is therefore proposed to incorporate a traction drive (34) in the drive train between the pairs of wheels (16, 20) involved which adjusts either the mean speed of the pair of wheels (16, 20) or the speed of the two wheels (22) within a pair of wheels (20) to the turning radii covered. The traction drive (34) is adjusted by means of a programmable regulating device (36). 2.3 A driving device of this type has applications particularly on agricultural tractors, construction or forestry machinery. <IMAGE>

Title: Unitary irregular hollow fibre reinforced resin parts prodn. - using flexible positive mould inflated to predetermined shape for lay=up, re-inflated for curing in rigid negative mould for accurate thickness
Inventor: KREBBER BURGHARD DIPL ING
IPC: B29C70/86
Filed: 1990-12-08
Abstract: Process and arrangement for mfr. of hollow pts. from fibre-reinforced synthetic resin, especially pts. with irregular outer contours, in which the impregnated fibres/mats or prepregs (16) are laid up on an inflated flexible positive mould (5). After laying-up, the internal pressure is reduced and the lay-up enclosed by an outer negative mould (6, 6'). The internal pressure is then increased to conform the lay-up to the shape of the outer mould and maintained during curing. The internal pressure is then released and the moulded pt. removed from the mould. USE/ADVANTAGE - Large unitary hollow mouldings, esp. irregular contours with small radii, e.g. aircraft fuselages. Compared with an assembly with the same rigidity etc., built up from separate sections, this invention requires less material, lower unit wt. and reduced mfg. time. Compared with DE2426095, which uses an inflatable elastic bag as positive mould to consolidate the lay-up during curing, this invention uses a positive mould of defined shape, permitting strict tolerances esp. with irregular contours or predetermined thicknesses. It is claimed to give irregular -shaped hollow articles with void-free surface quality with smallest possible wt., strict tolerance on wall thickness and shorter mfg. time in a single process.
