Patent DE-4204009-A1 (DE)
Inventor: WILDENBURG JOERG
IPC: C01B21/064
Filed: 1992-02-12
Abstract: A process is disclosed for preparing an amorphous ultra-hard material based on boron nitride that is sufficiently hard to scratch diamond. Hexagonal or turbostratic boron nitride hBN is compressed under pressures of at least 70kbar or more and heated up to temperatures of at least 1650  DEG C or more, until a molten mass of boron nitride is obtained. The thus formed molten mass of boron nitride is quenched by stopping heat supply, then the pressure on the quenched molten mass of boron nitride is relieved. The hexagonal or turbostratic boron nitride used as feedstock is treated in the presence of crystallisation inhibitors, so that no crystals are formed, and the amorphous crystalline structure is condensed by deposition of reaction products, such as boron suboxides.

Title: Sludge water extn. - has final electro=osmosis stage at low pressures with constant DC with pressure increases to maintain voltage as material dries
Inventor: KILLER ERIC
IPC: C02F11/15
Filed: 1992-03-20
Abstract: For the removal of water from sludge, it is thickened and water is extracted mechanically, followed by further water removal by electro-osmosis under pressure. The electro-kinetic water removal stage is at small pressures and a constant DC at 5-30 V at the start. As the voltage increases by more than 1-5 V, the pressure is adjusted upwards on increased water extn. until the voltage drop returns it to about the starting value. Pref., the pressure increase starts with low dry matter content rates of 10-20%. To reduce the anode voltage drop, a thin layer of 1-5 mm is applied continuously by a unit on the side of the sludge towards the anode, or a membrane is between the sludge and the anode and the anode is continuously wetted with an alkali soln. USE/ADVANTAGE - The system is for water extn. from sewage sludge. The end product has a very high dry matter content, with economic water extraction.

Title: Cable fabrication exchanging workpiece carrier - using unloading device which detects installed conductors in casings before returning their carrier to reloading station.
Inventor: KLAWONN UWE DIPL ING
IPC: H01R43/00

Patent DE-4235646-A1 (DE)
Inventor: JACOBS JOCHEN DR
IPC: C11D17/06
Filed: 1992-10-22
Abstract: High-density extrudates are produced under pressure, with a homogenous solid premix being pressed into a strand at these pressures and, following extrusion, the strand being cut up by a cutter to the predetermined granulate size, but with no essential increase in the pressure and thus in the specific work as the throughput is increased. This is accomplished by using in the extrusion premix a self-regulating system consisting of preparation constituents having intrinsically viscous effects and preparation constituents having dilatant effects. Since, in macroscopic terms, there is no change in the pressure in the compound sufficient to effect an essential change in the specific work, the extrusion throughput can be increased in a given system with approximately the same temperature or in the same temperature range as before the increase in throughput (approximate constancy of temperature). As a result, temperature-sensitive constituents, for example peroxy bleaching agents, can also be extruded despite the increase in throughput.

Abstract: The desired value of a parameter relevant to a movement of the vehicle is worked out on the basis of ascertained vehicular operating conditions by a digital control unit (16) which calculates a desired steering angle for one pair of wheels and adjusts them accordingly. When the calculated absolute value of steering angle exceeds a predetermined limit, the forces applied by the brake cylinders (1) to nearside and offside wheels are rendered unequal so that the parameter can be brought to its desired value. ADVANTAGE - Number of braking adjustments necessary minimised, waste of energy reduced and lifetime of braking system components prolonged.
