Title: Steering shaft for motor vehicles
Inventor: OTTO HEINZ DIPL ING
IPC: B62D1/16
Filed: 1987-01-28
Abstract: The invention relates to a steering shaft for motor vehicles with two sub-shafts inserted one into the other at their ends with a non-circular cross-section in their overlapping region. In order, on the one hand, to couple the two sub-shafts to each other in a simple manner without play and, on the other hand, to ensure as gentle and jerk-free axial insertion and pulling apart as possible, the sleeve-like, outer sub-shaft is provided at its free end with a cup-shaped, radial widened portion into which there is recessed an annular, rubber-elastic moulding. The inner contour of this moulding corresponds approximately to the inner contour of the sleeve-like, outer sub-shaft or the outer contour of the inner sub-shaft, and its axis of symmetry is - when the inner sub-shaft is not inserted - rotated by a small angle in the circumferential direction counter to the axis of symmetry of the inner contour of the outer sub-shaft. <IMAGE>

Patent DE-3712984-A1 (DE)
Title: Device for cleaning rolls of film
IPC: B43L1/08
Filed: 1987-04-16
Abstract: The invention is based on the object of cleaning and drying transparent films which are stored on rolls (reels, rollers) and are used in Hell printing system or so-called overhead projector for conveying information and which has been written on, and to wind it onto an empty roller. It consists essentially of two modules: A subassembly for guiding the film, which is inserted with a predetermined locking position in a water-filled bottom box in which two rotating damping rollers are provided. This obviates the arduous feeding of the transparent foil to be cleaned between damping rollers and guide rollers. All subassemblies which come into contact with water are made of corrosion-proof, swelling-resistant plastics, including the rolling bearings. A simply devised wiping and drying device results in a film which can be stored on rolls, is faultless, transparent, and re-usable. Rollers which rotate at a speed adopted to the traversing speeds of the film prevent damage such as scratches, tears, etc., developing in the film traversing the cleaning procedure and prevent the wound-up cleaned film from sticking. Transparent films having a width of up to 29.7 cm and having a length of up to 30 m can be cleaned. The invention serves to re-use rolls of transparent film which has been written on, and is thus a contribution to environmental protection.

Patent DE-3813825-A1 (DE)
Title: Method for regulating the circulating pump of a heating system
Inventor: SCHMITZ HERIBERT DIPL ING
IPC: F24H9/00
Filed: 1988-04-23
Abstract: The amount of condensate can, in the case of low-temperature boilers, be substantially reduced by switching off the circulating pump during the start phase of the burner, since then only the water present in the boiler is heated initially. With the subsequent switching on of the circulating pump, a surge of colder water enters the boiler, further causing a substantial reduction of the boiler water temperature until well into the critical temperature range. In order to prevent these strong fluctuations, the circulating pump is then first driven with a low output rate which rises with increasing boiler water temperature.

Title: Process and apparatus for blow moulding a hollow body from thermoplastic material
Inventor: REYMANN WOLFGANG
IPC: B29C49/12
Filed: 1988-05-04
Abstract: After enclosing a preform in a blow mould, a rod is introduced through the blowing mandrel. Subsequently, the stretching rod is displaced mechanically by means of a roller guide on a curved track and the preform is thereby prestretched axially by a certain partial length. In the process, a wall section of the preform, which is preferably shaped during blow moulding into a tapering neck section, is drawn out to a thinner wall thickness. After the prestretching, the preform is further stretched by means of the blowing air, the stretching rod being driven in such a way that it constantly guides the bottom of the preform centrally, and at the same time is opened out to form the finished hollow body.

Patent DE-3834201-A1 (DE)
Title: Arrangement for feeding pressure medium to hydraulic consumers
Inventor: EISENBACHER EGON DIPL ING
IPC: F15B21/08
Filed: 1988-10-07
Abstract: Several hydraulic consumers, in particular for driving auxiliary units of a motor vehicle, are attached to a variable displacement pump via electrically adjustable orifices or manipulating valves. The adjustment of the orifices as well as the setting of the delivery volume of the pump is effected electrically by signals which are characteristic of the supply demand of the individual consumers. According to the invention, the correct metering of the individual consumers is achieved and the pump output is set to the smallest possible value. When manipulating valves are used, a maximum delivery volume is briefly fed at maximum pressure to the respective consumer until a corresponding limit value of the associated controlled variable is reached, whereupon the drive is stopped. The complexity of the electrical control is reduced and the efficiency is increased. Furthermore, a power-steering mechanism with open centre can be attached to the pump via a flow-control valve, the losses of which are reduced by connecting a hydraulic consumer downstream.
Patent DE-3837202-A1 (DE)
Title: Laundry-quantity adaptation system with metering indication or with automatic introduction of liquid washing agent
IPC: D06F39/08
Filed: 1988-11-02
Abstract: The fully automatic washing machine is characterised in that it adapts its water consumption to the laundry quantity and therefore saves water, energy, washing agent and time. There is the possibility of selecting between a liquid washing agent or a powder washing agent. The liquid washing agent is introduced automatically and in a correctly metered manner. A metering indication for powder washing agent allows an exact washing-agent consumption according to the laundry quantity and according to the degree of soiling and the water hardness. Time-set rotational movements of the laundry-filled drum and periodically inflowing water (monitored by a pressure gauge) allow an optimum laundry-quantity adaptation system by means of the control. The absorption of the water by the laundry articles (dry laundry) located in the washing drum causes a pressure drop of the water when the water level is insufficient, this pressure drop being measured by the pressure gauge. The control regulates this water deficit, in that water flows into the drum for a few seconds (as a function of the water pressure). The drum rotates for approximately 10 seconds. The pressure gauge thereafter tests the pressure of the water by order of the control. In the event of a pressure drop or if the pressure is not reached, the operation is repeated. Designation: laundry-quantity adaptation system with metering indication or with an automatic introduction of liquid washing agent.
