Inventor: CHROMOV VLADIMIR GAVRILOVIC
IPC: D07B3/10
Filed: 1988-01-29
Abstract: The method includes drawing a bunch of elongated elements (1) from pay-off spools, forming a twisted article (3) by imparting a forced helical movement to the elongated elements (1), conveying the article (3) about a curvilinear path, forcibly rotating the portion of the twisted article (3) in the cuvilinear path about an axis connecting start and end of such a path at half the speed of rotation of the twisted article (3) in the zone where it is formed, and coiling the article (3) onto a take-up reel (4) by providing a pull force. In the course of movement of the twisted article (3) about the curvilinear path the tension force applied thereto by the take-up reel (4) is relieved by applying a brake (10) to the article (3) immediately prior to coiling it onto the take-up reel (4). <IMAGE>

Patent DE-3826187-A1 (DE)
Title: Expansion tool for hollow workpieces
Inventor: ROTHENBERGER HELMUT
IPC: B21D41/02
Filed: 1988-08-02
Abstract: Expansion tool for hollow and, in particular, hollow cylindrical workpieces. A first hand lever (16) is rigidly attached to a main body (1) of the tool, the said main body having a hole (12), and a second hand lever (11) is attached to it in a hinged manner. Mounted in the hole (12) is an expansion mandrel (14) with a tapered end (15) which can be displaced against a set of expansion jaws by means of the hinged hand lever (11). The hand lever is connected to the expansion mandrel (14) via a toggle lever (20) and there are three hinge pins (10, 21, 22), the first (10) supporting the hand lever, the second (21) connecting the hand lever (11) to the toggle lever (20) and the third connecting the toggle lever to the expansion mandrel (14). The arrangement of the hinge pins (10, 21, 22) is such that, by bringing the two hand levers (11, 16) together in the manner of pincers, they can be brought into a position closer to the extended position. In order to make the matter of tolerances less critical and to avoid overloading without the use of safety couplings, the pivoting angle of the two hand levers (11, 16) relative to one another is limited by a stop in such a way that the toggle lever (20) comes to a halt before the axes (A, B, C) of the three hinge pins (10, 21, 22) reach the extended position. <IMAGE>

Title: Lead accumulator
Inventor: WINSEL AUGUST PROF DR
IPC: H01M10/06
Filed: 1988-08-20
Abstract: The charge-acceptance capacity of the negative electrodes of a starter battery, which is greatly reduced at low temperatures under the freezing point of water by an expander additive, can, at the price of only a small deterioration in the cold-startability, be improved by reducing the expander concentration in a part of the electrodes of each of the negative plate groups and/or by these plates containing expander with comparatively low long-term power (for example alizarin red S). In addition, by means of different dopings of the negative plates with carbon black, which in the case of the progressive discharging absorbs and temporarily stores the expander released from the lead surface and, during recharging releases it back onto this surface, differentiated spreading effects can be produced with one and the same expander material. By this means, the originally set capacitance balance between the electrode polarities with capacitance limitation via the positive plates is retained even after repeated starting of the car.

Patent DE-3837729-A1 (DE)
Inventor: GEROPP DIETER PROF DR ING
IPC: B61D17/02
Filed: 1988-11-07
Abstract: This process for reducing the drag in the rear region of a vehicle, e.g. a road or rail vehicle or the like, has the essential feature that first air is caused to be blown out at a relatively high velocity (e.g. up to about 50 m/sec) in the separating line region (5) of a vehicle (3) (boundary layer blowing), that secondly the Coanda effect is used to ensure that the flow lies along a curved surface of the rear of the vehicle (3) and that the air blown from its original direction of flow is thus diverted into a dead region (4) (strongly eddying flow region in the rear region), and that thirdly the air from dead region (4) is deliberately drawn off again (boundary layer extraction). This raises the Bernoulli total pressure in the rear region and thereby sufficiently reduces or minimises the pressure resistance and hence the total drag. Said process may be implemented by fitting to the rear region of the vehicle (3) a device having blowers (11), outlet slots (9) at the edges of the outwardly curved rear wall (6) and extractor apertures (10) in the rear wall (6).

Title: Ignition device for a piston internal combustion engine with applied ignition, especially of motor vehicles
Inventor: HEUSER EDGAR
IPC: F02P7/02
Filed: 1989-03-13
Abstract: An ignition device for a piston internal combustion engine with applied ignition and cylinders arranged in line, especially of motor vehicles, has an ignition coil generating the high tension required and an ignition distributor electrically connected thereto, the rotor of which distributor is driven by the camshaft. The ignition distributor has a tubular distributor housing of a high tension-insulating material running in the direction of the cylinder bank of the internal combustion engine with electrical distributing poles corresponding to the number of cylinders and arranged in series on a level with the individual cylinders. A distributor shaft, supported in the distributor housing, acts as rotor of the ignition distributor, which shaft on its circumference has contacts staggered according to the number of cylinders and the firing order which contacts are electrically connected to one another and to the ignition coil and interact with the distributing poles of the distributor housing. The special feature lies in the fact that the distributor housing is integrally formed on to a cylinder head cover covering the valves of the cylinders off from outside, which cover is likewise composed of high tension-insulating material (plastic). The integral design of cylinder head cover and distributor housing makes easy and cost-saving manufacture and assembly of the entire ignition device possible.

Logic circuitry determines appropriate stator current with overload  limitation provided by thermal unit (35). A fixed direction of rotation is ensured by the asymmetric airgap. USE/ADVANTAGE - Particularly in areas where spark ignition of combustible dust cloud may cause explosion. Has efficient operating level at high powers and speeds, low inductance and high power/weight ratio. Vacuum increase to clear intake obstruction due to automatic increase in RPM.  No commodator to cause sparking at sudden load change. Less expensive than digitally controlled alternatives.
