Title: Reinforced trim strip for windows - has retaining ribs with extension lips seating against glass via widened ends
Inventor: FISCHER ROLF
IPC: B60J10/33
Filed: 1980-02-02
Abstract: The reinforced trim strip for windows especially around car door and window openings has a U-shaped extrusion (6) over a U-shaped metal reinforcing strip (5) and with a pattern of internal ribs to grip the glass ( 11). Three or more ribs (9) are mounted on one side of the strip, to grip one side of the glass while a single, large rib (10) on the other side of the strip grips the glass on the other side. The single strip has an extension lip (12) for an improved seal. The extension lip has a widened end to run over the glass. The unsymmetric arrangement of the lips ensures a good seal grip even with the window partially closed.

Title: Forming integral felt structure into combustible case - for ammunition components by pressing in moist state
Inventor: OVERSOHL WILHELM DIPL CHEM DR
IPC: F42B5/188
Filed: 1980-03-04
Abstract: Combustible ammunition components such as cartridge cases or propellant holders are made by the hot or cold pressing of one-piece felt structures made on formers by suction from aq. slurries, and have tapered sections at both ends, one of which may be a closed end and the other an aperture for insertion of projectiles, charges etc. The felt is kept moist during pressing and is initially 3-10(6-8) times as thick as the final prod. The process may be single stage with a separable outer die and an internal tool temporarily expanded mechanically or by fluid pressure, or a multi- stage process. The moisture content of the felt, initially over 3%is reduced e.g. by suction during the later stages of pressing. For felts made of nitro-cellulose fibres, inert fibres, stabilisers etc., and avoids the charges in strength porosity etc. caused when separate elements are joined, e.g. by adhesives.

Title: Multistage switching matrix - connects numerous signal sources to loads using orthogonal packets each comprising parallel circuit boards
Inventor: FLEISSNER HORST ING GRAD
IPC: H05K1/00
Filed: 1980-04-16
Abstract: Each stage of the matrix consists of numerous submatrices (10,11,26), each one containing a printed circuit board. The submatrices of any one stage are arranged parallel to one another a given distance apart to form a multi-layer packet that has all inputs in a first plane and all outputs in a second plane perpendicular to the first plane. The packets can be connected together via plug-type connectors. The planes of the boards in one packet are then at right angles to the planes of the boards in an adjacent packet. Each submatrix has at least one control module. Each control module contains a module-selection decoder with data inputs and control signal outputs. These outputs are connected to a enabling input of a module decoder in the control module of the submatrix. The matrix is capable of connecting e.g. 100 signal sources to 150 loads, and its advantage lies in the partic. short connection paths between the submatrices within any stage.

Patent DE-3042213-A1 (DE)
Inventor: HORNSCHUCH MANFRED
IPC: F16B37/14
Filed: 1980-11-08
Abstract: The device is used especially for covering wheel nuts on childrens' vehicles. A protective collar (1), which is joined together with a cap (3), is mounted on the flaps (6) of a clamping disc (2) by means of recesses (5) by twisting. As a result of the split design in the protective collar (1) and the cap (3), it is possible to achieve a large overlap of the flap (6) of the clamping disc (2) with the protective collar (1) so that the protective collar (1) cannot spring off the nut (4) which is to be covered even in the event of severe impact stresses. <IMAGE>

Title: Process and apparatus for cutting films of plastic
Inventor: HIRT EDMUND
IPC: B29C51/44
Filed: 1981-02-06
Abstract: In the case of the process for cutting films of plastic (2), which is to be used in particular in the case of packaging machines, a knife-like cutting tool (1) is pressed against the film, which is supported by an abutment (3). The cutting region of the film of plastic is heated, for example by means of the abutment (3), until below the melting temperature of the film of plastic, so that the toughness of the film is reduced. The forces necessary for cutting are greatly reduced, so that even cutting tools of a simple design can be used. <IMAGE>

Title: Pipe-pushing apparatus
Inventor: GESCHKE GUENTER
IPC: E21B21/12
Filed: 1981-02-18
Abstract: The invention relates to a pipe-pushing apparatus for inaccessible pipes, with a cutting head which can be pivoted by means of hydraulic control cylinders and a hydraulic flushing device for removing the soil material. According to the invention, the interior space of the cutting head (11) is covered towards the face by a deflector (33) which is designed like a grating and preferably like a conical basket or the like which is formed by a multiplicity of roughly radial ribs (34) distributed over the pipe periphery and having passages (41) in between. The arrangement of the deflector (33) and the end opening of the cutting head prevents the ingress of rock obstacles (erratic blocks) into the cutting head during the pipe-pushing operation. Rock obstacles can be flushed free to such an extent that they are pushed away to the side during the pushing of the pipe line. The cutting head (11) with its deflector (33) is preferably arranged in a pivotable manner on a trailing pipe which consists of several pipe sections (13 to 16), which are locked against rotation but can be angled towards one another to a limited extent, in order to permit directional control during the pushing of the line. <IMAGE>

Title: Period measuring device
Inventor: HIRANO TOSHINORI
IPC: A61B5/024
Filed: 1981-07-16
Abstract: The period measuring device according to the invention is capable of tapping or scanning a biosignal (biological signal) at a predetermined scanning period, and of determining an autocorrelation function for a variable  tau  with the aid of the scanned biosignal, and then of determining an autocorrelation function which corresponds to the magnitude of a phase difference variable which has been obtained by changing the variable  tau  along the time axis. An autocorrelation function determined in this way is stored in a memory and then compared with an autocorrelation function subsequently determined. The comparative operation is repeated for successive autocorrelation functions, in order in this way to determine a peak value of the autocorrelation functions for the purpose of measuring the period of the biosignal. <IMAGE>
