Patent DE-19709342-A1 (DE)
Title: Torsional vibration damper
Inventor: ORLAMUENDER ANDREAS DIPL ING
IPC: F16F15/131
Filed: 1997-03-07
Abstract: The damper comprises a pair of transfer elements (1,39), the output-side one of which rotates relative to the other, drive-side one. It is centred above a radial sleeve bearing (17) opposite the drive-side element and is maintained by an axial sleeve bearing (21) at a predetermined axial distance from the output-side element. One side of the axial sleeve bearing locates at a primary flange (2) of one of the transfer elements (1), where the flange grips the outer periphery (98) of the radial sleeve bearing. The other side of the bearing locates on the output-side cover plate (20) of the other transfer element (39), where the plate grips the inner periphery of the radial sleeve bearing. This, together with the flange and cover plate, creates a jacket around the radial sleeve bearing, protecting it against an undesired inflow of solid particles.
Patent DE-19709908-A1 (DE)
Inventor: REUBER CHRISTIAN
IPC: B60R21/13
Filed: 1997-03-11
Abstract: In order to reduce the costs of a locking unit for a motor vehicle roll bar which is extended in a crash, the ratchets used in the assembly should have a sandwich construction and subassemblies which can be pre-assembled should be realized. The sandwich of said ratchets (3) consists of several flat parts stamped from sheet- steel. Said parts are interconnected in such a way that they have a positive form fit or a positive material fit, thus producing perfectly joined ratchets. The spring block, which consists of spiral springs and a plastic absorbing and securing element, is defined as a subassembly which can be pre-assembled. This subassembly can be quickly pre-assembled with few manual operations, and after pre-assembly can be built into the assembly of the locking unit with a single manual operation. Both of the measures described are aimed at reducing material and manufacturing costs.

The activated central ray impinges on a front side (6) of the first depression and reflects against the full reflection front face (7). A converging lens (8) is provided at the point where the central ray intersects with the surface of the second wide side. The invention is a built-in module inside a component, which enables a low cost assembly on a printed circuit board (60) according to the CMS technology.

Patent DE-19739719-A1 (DE)
Inventor: SCHULZ WILFRIED
IPC: A01D67/00
Filed: 1997-09-10
Abstract: When the machine implements such as mower (24) and mower bar (25) strike a blockage (27) in the travel direction (FR) it leads to a relative movement between the tractor vehicle (4) and machine tool (2). This relative movement is transferred by at least one transfer member (17) to the agricultural machine tool which causes the machine implements (24,25) to be deflected vertically. The relative movement between tractor and machine tool is produced through a draw bar (9) comprising telescopically displaceable support sections (10,11).

Title: Method of measuring heat capacity of sample
Inventor: HATTA ICHIRO
IPC: G01N25/18
Filed: 1998-01-28
Abstract: The method involves applying alternating heat to a sample whose heat capacity is to be measured using a given repetition frequency of an ac heat source. The alternating temperature of the sample is determined. The heat capacity of the sample is measured on the basis of an amplitude of the temperature curve and a phase difference between the ac heat and the ac temperature. The heat may be applied to the sample by applying alternating current to a heating device near the sample. The method may be used to measure the heat capacity of a fluid sample. A sample cell (11) is used that has a tube (12), which can hold the fluid sample and is provided in a heat bath (13).

Inventor: LICHTINGER PETER
IPC: B29C45/00
Filed: 1998-03-06
Abstract: Disclosed is a method for producing molded parts consisting of several components, using plastic processing machines. Plastified plastic material is injected into two cavities formed by the halves of a tool for each component. A sprue element is provided at least for the first component (1). The invention is characterized in that the sprue element (4) of at least the first component remains in the mold and is totally or partially encapsulated by injection molding by the next component (5) during one of the following working cycles.

Title: Carpet tufting supports obtained from endless threads and useful in carpet and rug manufacture
Inventor: RUZEK IVO EDWARD
IPC: D04H11/00
Filed: 1998-05-15
Abstract: Surprisingly, spin bondings obtained from endless threads through the action of energy-rich water jets produce good hydroentanglement and strengthening, but when formed from fine denier threads in thread bundles (spun bonded) before treatment, they are at most only slightly pre-strengthened, and the mobility of the threads remains at the maximum. A high strength light tufting support is obtained from synthetic fiber spun bonds, where the spun bonds are strengthened (hydroentangled) and have a specific strength of at least 4.3 N/cm, and an initial modulus at 5% elongation of at least 0.45 N/cm per g/m<2> of surface.

Title: Method for monitoring contents fluid and gaseous and paste type fluids and for online exchange of data with data station
Inventor: WEIS WOLFRAM
IPC: G01N1/10
Filed: 1998-06-02
Abstract: The method monitors how the fluids stay within predetermined limits and parameters. The values of the contents of the fluid are continually determined by sensors in an on-line mode.
