Title: Determining position or setting of control column corresp. to certain control order
Inventor: SCHWARTING GEORG
IPC: G05G9/047
Filed: 1993-01-30
Abstract: Control measures are carried out in response to the identified alteration of the light signal, e.g. its intensity in the region of the control column (1). The light signal is reflected with a respective different degree of reflection, according to the position of the control column.The altered light signal is compared with a reference light signal, for the exact determination of the alteration.

Title: Method and device for producing brushes
Inventor: ZAHORANSKY HEINZ DR ING
IPC: A46B3/22
Filed: 1993-05-04
Abstract: A device (1) serves, in the production of brushes, for preparing completed bristle tufts. In this case, sections of bristle material (4) are fed to a looping device (6) with the aid of a feed device (5) and their free ends are processed there at the ends for later use. During this processing, the free length of the ends of the bristle section and thus also their lateral deflectability during grinding can be set precisely to this operation. This can be carried out in adaptation to different bristle material or even in adaptation to different rounding results as required. In this case, the actual length of the bristle tufts for later use is unimportant since the bristle tufts are only cut to length in a subsequent operation (Figure 1). <IMAGE>

Title: Process and apparatus for mounting entrance elements, in particular frames
Inventor: SOMMER GERD
IPC: E04F21/00
Filed: 1993-06-02
Abstract: The invention relates to a process and to an apparatus for mounting entrance elements, in particular frames of doors and gates, which comprise an U-shaped or closed frame and can be introduced into a corresponding rectangular or square masonrywork clearance and fastened there, the hollow space formed between the frame profile and masonrywork or lintel being filled by means of a setting composition. According to the invention, first of all the frame which is to be mounted is secured on a mounting apparatus, which can be adjusted in the vertical and horizontal planes, and is guided into the clearance. Thereafter, the mounting apparatus is fixed in its position by securing means and the frame is fixed in the vertical plane and in the horizontal plane by aligning means arranged on the mounting apparatus. In this arrangement, provision is made for a mounting apparatus which exhibits clamping members which vertically position and fix the frame, can be positioned approximately perpendicularly and are each arranged on a height-adjustment device which is suitable for vertical adjustment. Said clamping members bear at least one setting and locking device which is suitable for the horizontal positioning and fixing of the frame. <IMAGE>

Title: Method and apparatus for grinding, in particular belt-grinding machine
Inventor: ZOELLIG GUENTER DR
IPC: B24B19/12
Filed: 1993-06-11
Abstract: The invention relates to a method for grinding rotating workpieces, in particular camshafts, as well as to the design of a grinding tool, in particular a belt-grinding machine for machining camshafts, crankshafts and the like. The aim is to use and design methods and apparatuses of the type mentioned in a more efficient manner. This is achieved by the use of twin grinding units, in particular fork-type forming shoes (9; 209) for two grinding belts (7, 8; 207, 208), with which rotational bodies lying close beside one another, such as cams (3, 4, 5) of a camshaft (1), can be machined alternately by two grinding belts or in each case one of the grinding belts. In this way, the machining times can be reduced and the wear on the grinding tools evened out. <IMAGE>

Title: Doppler effect speed measurement device for vehicle - transmits light to and receives it from road surface, computes speed using Doppler effect and compares with speed derived from wheel speed
Inventor: MIZUKOSHI MASASHI
IPC: G01S13/60
Filed: 1993-06-18
Abstract: The Doppler effect speed measurement device includes a transmitter which sends light waves to a road surface, a receiver of light reflected from the surface and a signal processor which derives the ground speed of a vehicle from he frequency of the radiated and reflected waves using the Doppler effect. A vehicle speed computation arrangement derivs a computed speed from the revolution rate of a vehicle wheel. The signal processor determines the relationship between the computed speed and that derived from the Doppler measurement. The relationship is used to derive a final speed value for uniform vehicle motion. USE/ADVANTAGE - For accurately and reliably measuring ground speed of motor vehicles, e.g. for antilock or antislip control systems.

Title: High frequency welded encapsulation and spot bonding
Inventor: STOCZEK LOTHAR
IPC: B29C59/02
Filed: 1993-09-24
Abstract: Forms a high frequency welded bond between a sheet encapsulating material - a high frequency (HF) weldable polar plastic, and a non HF-weldable plastic body. The body, having holes (5), together with sheet(s) of the polar material (3), are sandwiched between the upper (1) and lower (2) electrodes of the HF welding machine. On heating, the holes fill with molten plastic, which, when cooled, forms the bond. If a sandwich of two fusible outer sheets is used, through-hole bonding results. If a single upper fusible sheet is used above upwardly-tapering holes (7) in the non-meltable body, then the cooled and resolidified plastic in the holes forms a keyed-in physical form-bond. Methods of marking the capsule surface and sizing the holes in the body are also claimed. In addition the encapsulated product itself, made by the process described, is claimed.

Patent DE-4400450-A1 (DE)
Inventor: SEKINE HIDETOSHI
IPC: B60K15/035
Filed: 1994-01-10
Abstract: A pressure reducing valve 21 with a breathing hole (24, Fig. 2) is provided on the upper wall of a fuel tank (2), the valve being opened to allow vapour to flow into a vent line (9) by an actuating means responsive either to the presence of return fuel in line (8) from a pressure regulator (7) or to energization of a fuel pump (3) which supplies fuel to the engine (5) and the pressure regulator. A fuel cut-off valve (22) with a leak hole (22d) may be provided next to the pressure reducing valve (21) or alternatively a fuel vapour storage device. The actuating means may comprise a float value (23b) which actuates both the pressure reducing valve and the fuel cut-off valve via an interconnecting rod (23c). When an engine is running, the pressure of return fuel raises the float valve (23b), whereby the pressure reducing valve (21) is opened and the fuel cut-off valve (22) is closed. When the engine is stationary, causing a zero pressure in the return fuel, the float (23b) drops, so closing the pressure reducing valve (21) and opening the fuel cut-off valve (22). When valve (21) is closed the fuel vapour is slowly discharged through the breathing hole. <IMAGE>
