Patent DE-3831025-A1 (DE)
Title: Safety chock
Inventor: ROSSMANN VIKTOR
IPC: B60Q7/00
Filed: 1988-08-16
Abstract: The safety chock, also called a skid, is also specially equipped for winter and is provided with many safety factors. The main focus of the safety chock lies in the fact that the underside of the safety chock is provided with all types of anti-skid profiles such as steel pins, anti-skid serrations, anti-skid ribs, claws, grooves etc., and also that it can be folded in and folded out. The anti-skid plate of the safety chock has furthermore also been provided with a built-in anti-skid plate heating system. These anti-skid profiles and the anti-skid plate heating system provided result in the elimination of the former slippery, icy supporting surface of the skid. The built-in anti-skid plate heating system melts the snow and the ice in minutes from the asphalt pavement or from the road surface. This universal safety skid consequently always has an optimum, secure hold even in winter in snow and ice. As an additional safety device the safety chock has been arranged such that it can also be slid onto the chock-securing device and locked, and has also been provided with a retractable or fold-in drive-on aid, cf. Fig. 6. <IMAGE>

IPC: D02J1/08
Filed: 1989-02-17
Abstract: Known air plates consist of a number of baffle plates and intermediate plates of smaller height, above which the baffle plates 10 form a gap. Air nozzles 28 are directed into the gap. To improve the knotting effect, a swirl chamber in the form of an elongate groove 14 is located opposite the respective air nozzle 28. The baffle plates also form underneath the groove a gap, through which the air can escape, so that no build-up of air occurs in the region of the swirl chamber 14. <IMAGE>

Patent DE-3908657-A1 (DE)
Inventor: ENGERT KLAUS DIPL ING
IPC: B60T13/14
Filed: 1989-03-16
Abstract: In a brake power hydraulic booster, the initial positions of booster piston (2) and control slide (8) and/or actuating piston (5) are defined by a stop (27) on the housing such that a fluid return bore (14) to a reservoir (31) is almost closed when the pistons are in their initial positions. Upon actuation and subsequent release of the brake, the control slide (8) is slid back relative to the booster piston (2) so far that the cross-section of the fluid return bore (14) is completely open, thereby permitting the pressure fluid to discharge from the booster chamber (4) into the supply reservoir (31) without resistance. This combines a small lost travel on initial actuation with a rapid release of the brake. The stop for the pistons (2, 5) is provided suitably by an L-shaped sleeve (27). <IMAGE>
Patent DE-3908763-A1 (DE)
Inventor: TELSER THOMAS DR
IPC: G03C8/36
Filed: 1989-03-17
Abstract: For the production of a flexographic relief printing plate, a novel photosensitive printing component is used having a dimensionally stable backing (A), a photopolymerisable printing layer (B) forming a relief image and consisting of at least two individual layers (B), and an optically transparent covering layer (C) securely adhering to the surface of (B). When the photopolymerisable printing layer (B) of the novel photosensitive printing component is exposed to actinic light in the form of an image, a difference in solubility is produced between its exposed and unexposed areas so that its unexposed areas may be washed off (developed) by a solvent. The optically transparent covering layer (C) of the novel photosensitive printing component cannot be dissolved or washed off by the solvent concerned. The novel photosensitive printing component can thus be developed in one working cycle using a "water in oil" or "oil in water" emulsion. These emulsions are also suitable for developing exposed photosensitive printing components whose polymerisable relief image layers (B) consist of at least two individual layers (B) of differing solubility. Here, too, development is completed in one working cycle.
Patent DE-3911789-A1 (DE)
Inventor: STOG JOCHEN
IPC: C02F3/06
Filed: 1989-04-11
Abstract: The invention concerns a process for the biological treatment of waste water using microorganisms, in which the microorganisms breed and develop in a contact path (1) and in which optimum living conditions are maintained for the microorganisms by the addition of waste water to be treated and appropriate quantities of air (2). A portion of the microorganisms leaving the contact path (1), which will have developed well in the soiled water, are fed back (6) into the contact path in order always to have exactly those microorganisms available that are particularly suitable for the waste water to be purified and at the same time sufficient quantities of these healthy microorganisms. In addition, a small sample of waste water is taken, well away from the contact path (1), as an indicator, and introduced (17) into the microorganism development area as a kind of early-warning enabling timely preparations to be made for the development of the microorganisms. This process, together with a device suitable for carrying it out, enables the degree of purification to be kept constant, the uniformity of the food supply and the wide and optimally balanced variety of microorganisms, as well as the balanced oxygen supply or efficiency of aeration, making it possible to adapt several variables, either individually or together, to changing conditions.
