Title: Process for the biotechnological production of L-malic acid
IPC: C12P7/46
Filed: 1984-09-22
Abstract: L-malic acid is produced at a concentration of 170 to 400 g per litre and in a high yield by biotechnological conversion from fumaric acid, neutralised by ammonium hydroxide, in a nutrient-free solution or suspension. Pure L-malic acid can be extracted therefrom in an economical manner with high productivity in a quality suitable for foods and pharmaceuticals. The fermentation is carried out in simple vessels under non-aseptic conditions. The rate of conversion of the fumarate and the concentration attainable of the L-malate are favoured by ammonium ions.

Patent DE-3517292-A1 (DE)
Title: Rotary engine
Inventor: BUHMANN FRIEDRICH
IPC: F01C1/44
Filed: 1985-05-14
Abstract: The rotary engine is a very important improvement in terms of the efficiency of all engines than was hitherto possible with reciprocating engines, because the rotary engine III comprises considerably fewer components, has a lower energy/heat loss and functions without uneconomic mass acceleration of reciprocating pistons and connecting rods. It is the first really complete centrically rotating rotary piston engine for all engines for liquid substances and gases/fuels, which can achieve a very high exploitation of the primary energy used and helps to reduce pollutant emissions from internal combustion engines due to unleaded petrol or other fuels and also improved combustion. It largely replaces many engines of the spark ignition, Diesel, Wankel, Stelzer, Ramelli, Wittig, Dillenberg types, etc.

Patent DE-3525107-A1 (DE)
Title: Drive and service brake system for motor vehicles
Inventor: MAURER NORBERT
IPC: B60W10/18
Filed: 1985-07-13
Abstract: Due to the correspondingly large design of intermediate accumulators for auxiliary energy (battery, compressed air reservoir, coolant tank etc) and a pedal switch (2) coupled to the accelerator pedal (1) the drive and service brake system permits the auxiliary energy motors (alternator, compressor, fan, etc) to be switched on preferably whenever and for as long as the driver eases off on the accelerator but the speed of travel is still relatively high. A proportion of the brake energy otherwise consumed by energy dissipation is thereby made utilisable in the form of auxiliary energies (without a centrifugal accumulator being required). This also avoids additional power for auxiliary drives, possibly at times of high power demand, for example when starting, having to be drawn off from the main engine power output. Switching is performed separately for each auxiliary energy motor by means of electric clutches (5, 6, 7). These electric clutches are usually engaged in the deenergized condition but, in addition to operation by the pedal switch (2), can also be operated independently of the pedal by overload limit switches (8, 9, 10) and by minimum value switches (14, 15, 16) in order to ensure operating reliability of the system regardless of braking intervals. With corresponding design of the auxiliary motors these can even be connected as auxiliary drives briefly assisting the drive operation (for example for starting acceleration), in that, for example, the generator, functioning as an electric motor, and the compressor, functioning as a compressed-air motor. ...

Title: Non-spherical condenser
Inventor: HUND HELMUT DIPL ING
IPC: G02B21/08
Filed: 1985-09-13
Abstract: A non-spherical condenser is described whose non-spherical surface is formed by the rotation of a higher order parabola. Inserting constant values (c constants) into the individual terms of the parabola equation, a deviation of the curve from the mathematically exact parabola form is achieved which results in a condenser having maximum brightness and maximum achromatism. The individual x and y values (= h and p values) of the curve are specified concretely.
