Patent DE-3727245-A1 (DE)
Inventor: BRECHT ALFRED DIPL ING
IPC: H01R43/042
Filed: 1987-08-15
Abstract: The notching tongs for crimping end caps, cable shoes and connectors on electrical conductors has mutually crossing tong limbs (1, 2) of flat spring steel which are connected to one another at the crossing point via a hinge bolt (3). The two limbs (1 and 2) of the tongs each consist of two identical shells (1', 2') arranged parallel to one another. To ensure that they spring back when they are pressed beyond the crimping position, each of the shells is provided with a longitudinal slot (9) which extends via the hole for the hinge bolt, originating from the edge on the jaw side. When the tongs are closed, the slots 8 are aligned in the central longitudinal plane of the tongs. The slots permit the handle sections (1b) and (2b) to spring back when they are pressed beyond the crimping position in order to disengage the latch (11) with the toothed catch projection (12) when the tongs are pressed beyond the crimping position. <IMAGE>

Patent DE-3800002-A1 (DE)
Title: Crankshaft of an axial motor
Inventor: ELSBETT LUDWIG
IPC: F01B3/00
Filed: 1988-01-01
Abstract: The intention is to configure crankshafts for motors with an axial cylinder arrangement having oblique crank pins for the reception of a wobble-plate or similar mechanism in such a way that they are easy to manufacture and assemble. A further intention is to eliminate machining processes which require special machines. The invention therefore proposes to divide the manufacture and assembly of the mechanism into three parts which allows all the parts to be finished before assembly and in which the oblique crank pin is subjected to compressive stress over its entire length to allow it to accept high loads.
Patent DE-3800297-A1 (DE)
Title: Damping device for a motor vehicle manual shift transmission
Inventor: KODWEISS JUERGEN
IPC: F16H57/00
Filed: 1988-01-08
Abstract: The oscillating movements of the loose gears of a manual shift transmission, which cause an unpleasant rustling noise are damped by annular segments, which are fixed in the oil-filled transmission housing and surround the loose gears with a narrow radial gap. The annular segments are formed on coil shells, which are fixed on the inside wall of the housing. When an electrical current is applied, the coil windings situated in the coil shells give rise to eddy currents in the loose gears made of steel and produce an eddy current damping in addition to the hydraulic damping.

Inventor: STUTZ HERBERT DR
IPC: B29C70/08
Filed: 1988-04-14
Abstract: The invention relates to fibre composites consisting of prepreg layers which are bonded to one another by intermediate layers. The prepreg layers consist of laid webs impregnated with curable resins. The intermediate layers contain regions of flexible polymer films which cover 10 to 90% of the surface of the prepreg layers.

Patent DE-3816162-A1 (DE)
Title: Palletising apparatus for the manual palletisation of bobbins and means for operating the apparatus
Inventor: GEBALD GREGOR DIPL ING
IPC: B65G57/02
Filed: 1988-05-11
Abstract: In order, during the manual palletisation of conical or cylindrical bobbins, to ensure checking by visual appearance and, at the same time, make the physical stacking work easier, the bobbin stack is built up on a bobbin-lifting table to be lowered with a growing stack, whilst the operator stands on a lifting worktable to be raised with a growing bobbin stack. Delivery of a finished bobbin stack becomes easier if the bobbin-lifting table is designed in the manner of a fork-lift truck. The palletising apparatus can service a multiplicity of bobbin-delivery machines if it is arranged as a whole on a travelling unit.
Patent DE-3817292-A1 (DE)
Title: Torque dividing transmission
Inventor: WUEST BERNHARD DR
IPC: F16H47/04
Filed: 1988-05-20
Abstract: In a hydrostatic-mechanical torque dividing transmission with a four-shaft planetary differential gearing and two hydrostatic units, the hydrostatic units, viewed in the longitudinal direction, are arranged between the planetary differential gearing and the drive-side transmission end wall. All shaft connections on the planetary differential gearing are led out to the same side and the hydrostatic units are arranged at a small interval from the transmission longitudinal axis, so that the transmission has a small width. The mass concentration on the transmission input side and the functional assembly of the hydraulic control in a common control unit is also advantageous. The rear side of the transmission is thereby also free for the flange mounting of other assemblies.
Patent DE-3820641-A1 (DE)
Inventor: DUCKECK RALF
IPC: H04H60/25
Filed: 1988-06-18
Abstract: In evaluating the digitally encoded traffic information received in a data telegram, the latter is continuously decoded and the traffic information is stored after decoding and evaluation. On the receiver side, a computer must continuously evaluate the incoming data flow. As evaluation is difficult, especially in poor transmission conditions in which errors must be corrected, the computer would require a very complex program structure and configuration. To attain a simpler computer configuration and program structure, a complete traffic information cycle is first decoded and then stored after the correction of any errors. Thereafter an updating bit in the data telegram, which may change as the traffic information alters, is identified and evaluated. Depending on this evaluation, a further complete cycle of traffic information is decoded and stored only if the updating bit changes.

Title: Process for the hydrogenation of coal
Inventor: WUERFEL HELMUT DR ING
IPC: C10G1/08
Filed: 1988-09-08
Abstract: In a process for the hydrogenation of coal, using a reactor system through which coal and hydrogen are passed in counter current, it is proposed to divide the reactor system into a plurality of reaction zones, each reaction zone having its own hydrogen feed and its own product vapour take-off. This prevents fully reacted higher-boiling product vapours passing from a downstream reaction zone into the upstream zone and contributing there to a reduction in the reaction volume.

Patent DE-3904965-A1 (DE)
Title: Motor-operated pruning saw
Inventor: UHMANN GEB GEHNE
IPC: A01G3/08
Filed: 1989-02-18
Abstract: The motor-operated pruning saw is set up from the ground and actuated such that there is no need to work from ladders. For carrying out the sawing operation, the saw is arranged such that it can pivot about a retaining device - saw unit in the following. The saw unit and the telescopic extensions necessary for reaching the cutting height are raised vertically by hand and, by means of the retaining device, suspended on desired branches of the tree which is to be cut back. If the branch to be cut can be reached, the telescopic extension is connected to the telescope. The saw unit is then aligned into the cutting position and the branch to be cut off is braced, by means of the winch of the telescope, directly beside the cutting point, between the steady of the retaining device and the ground. The saw cut can thus take place in a controlled manner against this steady. Pivoting of the saw for the cutting procedure by means of a cable pull and the switching of the saw take place from the telescope. The saw unit may also be tilted, with the result that oblique cuts, e.g. for cutting back trees, may also be carried out.

Title: Wallet for identity card - incorporates pressure region to prevent card from accidentally slipping out
Inventor: SCHAEFER KARL FRIEDRICH
IPC: A45C11/18
Filed: 1989-07-26
Abstract: The invention concerns a wallet for holding an identity card, a bank card or similar card. The wallet is so designed that the card is prevented from accidentally slipping out. This advantage is achieved by one of several methods. In the first method an oval region (G) is formed in the wallet wall. This region (G) is so shaped that it exerts pressure on the card to hold it in the wallet. In another method the wallet is made wider than the card with the ends (K) of the extra width sealed to form a side pocket. One edge of the card can be pushed into the pocket by means of cut-outs (6) in the wallet edges. Other methods involve using a magnetic strip (F) or a suction pocket (H). USE - Wallet for identity card.
