Title: Evaluating characteristic absorption of mixed materials e.g. gases
IPC: H01S3/00
Filed: 1993-12-10
Abstract: A laser beam has wavelengths which alternate between those characteristic of each material to be measured and one which is uncharacteristic. This is used to establish a measurement path through the mixed materials (5) and a reference path outside the mixed materials (6).  The outputs are converted to electrical signals and a measured value is produced from the difference of the measurement path signal and reference signal. By time and or frequency domain analysis, the differential signal may be corrected before final measurement.

Title: Locking device for commercial vehicles
Inventor: NAPIERALA WERNER
IPC: B62D33/07
Filed: 1993-12-18
Abstract: The invention relates to a locking device between the chassis and driver's cab or dump body of a motor vehicle, in which device, for the purpose of long-term, rattle-free locking, there are provided two curved cams which are mounted rotatably in mirror-image fashion to form a trough-shaped receptacle on one commercial-vehicle part for a retaining bolt fastened to the other commercial-vehicle part, which curved cams are each prestressed in such a manner, by means of a spring, in the direction of the receptacle that they partially cover the receptacle and with the retaining bolt inserted in the receptacle, with their curves formed on the outer contour, rest in a force-fitting manner against the retaining bolt and press the latter into the receptacle. The curves of the curved cams are designed as clamping curves at a radial distance from the pivoting point of the curved cams which increases continuously counter to the rotational direction of the curved cams, which direction is brought about by the springs. An unlocking unit engaging on the curved cams is designed in a manner such that the curved cams are simultaneously rotated, counter to the spring prestressing, through approximately the same angle of rotation.

Title: Shower head base outlets
Inventor: BERGMANN KONRAD DR
IPC: B05B15/528
Filed: 1994-06-04
Abstract: The base part (4) of the shower head (1) has a ring shaped projection (6) which reaches out beyond the underside (5) of the shower head and has the water outlets (3) distributed over the projection's length. The projection includes a ring segment and pref. comes in closed ring form in which the water outlets issue at the topmost point of the projection. The outlets can also be arranged round the circumference of the projection at 6 deg. intervals. The base can also be formed from a ring and the projection adjoins the base in an area where the ring shape (4) is U shaped in section. A narrow part of the water outlet (3) is followed by the issuing end of the outlet which is itself bevelled to suit the direction of the water, the outlets designed so that adjoining outlets emit water in different directions. Assuming water directions to cover a range of 0 to 16 deg. to vertical, adjoining outlets produce a periodically repeating water spray pattern of notably 8, 5, 8, 5 and 2 deg.

Patent DE-4433452-A1 (DE)
Title: Automatic jockey wheel brake
Inventor: BUETOW ERICH
IPC: B60T1/04
Filed: 1994-09-20
Abstract: The problem was to adapt the device to all types of jockey wheels and to brake the wheel in only one direction of rotation. The solution to the problem lies in the arrangement of the components. For this purpose the wheel mounting (fork) must be extended forwards by 3cm in order to bring it out of the wheel centre. A U-shaped bracket is fixed to the extension so that it bears on the tread surface in front of the wheel apex and is always automatically tightened. A small spring holds the initial contact between bracket and wheel. The direction of rotation of the wheel is determined by the type of jockey wheels. In the opposite direction of rotation the brake releases automatically. The main sphere of application is to be found in motor car trailer operation, so that unhitched trailers on solid ground do not roll away.
