Title: Drilling auxiliary device
Inventor: BECHER REINHARD
IPC: B23Q11/00
Filed: 1983-01-24
Abstract: The drilling auxiliary device serves for the dustfree production of straight bore holes in walls etc. and for the production of mutually aligned bore holes and edges in the right-angled connection of boards by means of pins. The drilling auxiliary device consists of a rectangular plate 1 with a hollow cylindrical neck 12 which extends upwards at an angle of 90 DEG  and into which a likewise hollow cylindrical extension 13 is inserted. A lid 25 provided with a cellular-rubber coating 26 can be pushed onto the underside of the plate 1. With the drilling machine inserted, the drilling machine neck bears against the extension 13, 22 and the drill is guided through a drilling sleeve 3 inset in the plate 1. A container is thus created, from which no drilling dust can escape and straight bore holes are produced by means of the double guiding of the drilling machine. By means of pins 9 which can be inserted into the plate 1, the bore holes can be drilled on all boards with the same distance to the longitudinal and transverse edge, in the case of boards to be connected at right angles. A depth scale arranged on the extension 13 and a fixing ring 21 make possible accurate adjustment of the drilling depth. <IMAGE>

Title: Spoiler, as a slipstream-guiding device, for an engine bonnet
Inventor: WEBER AUGUST
IPC: B62D35/00
Filed: 1983-03-21
Abstract: The invention, or the innovation, serves to better direct the slipstream on a motor vehicle and thus also improve the Cd value, and analogously also has the purpose of bringing about a lower fuel consumption. The path taken by the slipstream in the region of the windscreen lies in the upper region of the windscreen due to the design of the bonnet spoiler. It is to be expected that the windscreen is no longer soiled to such a high degree by the water thrown up by other vehicles and the visibility for the occupants of the vehicle or for the driver is positively influenced. The risk of injury for persons thrown onto the engine bonnet in accidents is reduced because the engine bonnet spoiler protrudes vertically above the windscreen wipers. The advantages indicated are achieved in that, according to the invention, a spoiler referred to as bonnet spoiler (1), Figs A, B and C, is attached on the rear part (2) of the engine bonnet. <IMAGE>
Patent DE-3319485-A1 (DE)
Title: Brake pressure control unit for a hydraulic vehicle brake system
Inventor: STEFFES HELMUT
IPC: B60T8/26
Filed: 1983-05-28
Abstract: A brake pressure control unit is proposed, in which the reduced brake pressure phase is divided into a pressure reduction section and an adjustment section. The unit has a first valve piston (1), displaceable against the force of a first control device (28), and a second piston (2) which is displaceable against the force of a second control device (25). The piston (2) can be applied by a stop device (33) against an axial stop (22) of the valve piston (1). The stop device (33) is formed by the one end of an elastic element (32) supported by the other end on the piston (2). Due to the coupling of the valve piston (1) and the piston (2) by way of the elastic element (32), when the piston (2) is displaced the valve device (18, 19) does not open jerkily, rather controlled opening determined by the elastic element (32) and an adjustment of inlet and outlet pressure occurs. During the pressure reduction section the pressure is reduced entirely uninfluenced by the piston (2). Owing to the low number of dynamic seals, the unit has a precise control characteristic. <IMAGE>
Patent DE-3328990-A1 (DE)
Inventor: MECKE NORBERT DR
IPC: B41J31/05
Filed: 1983-08-11
Abstract: A thermocolor ribbon comprises a plastic support foil, a fusible color layer attached to one side of the plastic support foil and an organic coating layer covering the other side of the plastic support foil. The organic coating layer is composed of a nonfibrous, pressure-stable wax or waxlike substance. A process for making the thermocolor ribbon from a plastic support foil having a fusible color layer thereon comprises application of a solution containing an organic coating material to the side of the foil not having the fusible color layer bonded thereto, followed by solvent evaporation. Alternatively, the side of the support foil bearing the fusible color is brought into intimate contact with opposite side of the foil whereupon the latter is heated for a time sufficient for transport of material from the fusible color layer to the uncoated side of the foil to form the organic coating layer thereon.

Title: Heat-vulcanisable tread strips for producing the treads of motor vehicle pneumatic tyres
Inventor: NORDSIEK KARL-HEINZ DR
IPC: C08L9/00
Filed: 1984-07-05
Abstract: The invention relates to heat-vulcanisable tread strips which are obtained from virgin, vulcanisable compounds and can be used to produce the treads of motor vehicle pneumatic tyres. The vulcanisable compounds are based on a rubber component which contains a special virgin rubber component based on isoprene. The tyre treads have a good overall range of service characteristics which can be described by the following combination of properties:   a) high flexibility at low temperatures, that is to say retention of the elastomeric state to below -30 DEG C (good cold properties); b) high damping over a broad temperature range and correspondingly good wet skid resistance (safety); c) high abrasion resistance and correspondingly high running performance (economy).   The tyre treads have all-weather characteristics so that the tyres can be used as all-year-round tyres.
