Title: Prodn. of thermoplastic component with cheap tools - by depositing e.g. several coatings of polymer powder including blowing agent on core tool and blowing prod. off core inside blow mould.
Inventor: WOLFF MARTIN
IPC: B29C33/46
Filed: 1992-07-28
Abstract: A plastic component (or part of one) is produced by causing a liquid or (pref) powdered polymer to adhere to a heated core tool and solidify to form a sealed by sufficiently elastic layer; this is then blown off the core in an outer mould so as to give it the required shape and surface texture. ADVANTAGE - The method is inexpensive and produces single to multi-layer constructions. It uses cheap tools. The products are readily released from the tool without any further operations and have a good finish. In an example, of the process produce components for car interiors. To make a laminate type a core is first heated and exposed to a thermoplastic powder which forms a coating on it. This is heated to plasticate it and a second layer of a thermoplastic resin plus blowing agent is similarly deposited on top. This is heated to plasticate it and activate the blowing agent and a third powder is similarly applied as a decorative layer. The product is blow moulded to shape, with its inner tool (1), foam (2), decorative layer (3) and grain (4) in the finish. The complete layer is blown off the tool and cooled in the mould.
Patent DE-4225886-A1 (DE)
Inventor: SCHUSTER GEORG DIPL ING
IPC: C02F11/145
Filed: 1992-08-05
Abstract: The invention relates to additives for conditioning and preliminary dewatering and for downstream solidification of sewage sludges and organic sludges, which exhibit the following features:   (I) they contain at least two components, of which at least one component is selected from the group A which comprises:     (A) fine lime (CaO) and   hydrated lime (Ca(OH)2), and one further or two further components selected from the group B, which comprises:     (B) clays and   kieselguhr;   (II) the weight fractions of the components A and B in the total mass of A and B, the sum of which is always 100% by mass, are as follows:     total mass fraction A: 50 to 98% by mass,   total mass fraction B: 2 to 50% by mass     The invention further relates to processes for the preparation and the use of these additives for the production of sludges suitable for landfilling. These additives, in the sludge solidification, in comparison with conventional additives, lead to significantly higher, adjustable firmnesses of the solidified products, which at the same time have lower extractability and thus give a low leaching water load in landfills. The conditioning according to the invention leads to higher dry matter contents of the pre-dewatered products.

Title: Control of generator in car - has voltage controlled between maximum and minimum values, dependent on battery state and duration of acceleration
Inventor: BRINKMEYER HORST DR ING
IPC: H02J7/14
Filed: 1993-03-12
Abstract: To control the generator of a car, its set-point voltage has a minimum and maximum value, the minimum being when the car accelerates and the maximum when it brakes. The nominal value lies between these values. When the acceleration period exceeds a certain duration, the value of the minimum voltage is increased to the nominal value. The maximum value is dependent on battery temperature and the actual battery voltage is controlled so that the charging current does not exceed a threshold. The minimum voltage value depends on the battery current so that the battery is neither charged nor discharged during acceleration. ADVANTAGE Simple and inexpensive to ensure long battery life.
