Title: Hepatitis-safe prods. from citrate-stabilised plasma - by treating with ion exchange resins in the prepn. of anti:haemophilic globulin A, prothrombin complex, fibrinogen and a serum protein
Inventor: KOTITSCHKE RONALD DIPL CHEM DR
IPC: C07K14/755
Filed: 1979-01-27
Abstract: The Parent Patent described the prepn. of an antihaemophilic globulin A (factor VIII) contg. concentrate together with a prothrombin complex (Factors II, VII, IX and X) and a soln. of storage stable serum protein, using a frozen ion exchanger plasma as starting material, which had been thawed at 2-8 degrees C and in which the supernatant plasma liq. had been sepd. from the Factor VIII-contg. protein ppte. to give a Factor VIII concentrate after work up of this cryoppte. The plasma liq. was freed from Factors II, VII, IX and X by adsorption over commercial tricalcium phosphate. Any coagulation factors or other unstable proteins remaining in the plasma liq. were adsorbed over colloidal silica gel of specific surface 50x400m2/g. A storage stable serum protein remained. In this addition, the starting material is a citrate plasma, and after thawing and sepg. the cryoppte, the supernatant is treated with a polystyrene/dibenzene/quat. amine anion exchange resin and polystyrene/sulphonate cation exchange resin. Three hepatitis-safe and therapeutic prods. can be obtd. from blood plasma stabilised with citrate as well as a fourth prod., fibrinogen. The amt. of coagulation is reduced. Citrate blood from plasmapheresis and blood donors can be used, because the disadvantages associated with the addition of the stabiliser are removed by the treatment with the ion exchangers.

Title: Protection circuit for machine tool - senses magnitude of load imposed by tool feed and interrupts hydraulic supply on overload
Inventor: ANGERER MANFRED
IPC: F16P7/00
Filed: 1979-03-21
Abstract: The protection circuit controls machine tools with a hydraulic motor providing a linear drive to a tool, e.g. in a planning machine or a boring mill. It senses the load imposed on the hydraulic motor by the reaction between tool and workpiece, and at a preset load level switches the hydraulic power supply off. A pressure sensitive electrical switch(6) is connected to the pressure side(15) of the hydraulic motor(1). If the pressure in the feed linen8) exceeds this switch setting a circuit is closed. A solenoid(4) is energised and operates a hydraulic relay(3) to disconnect the pump delivery(7) from the hydraulic motor. By acting directly on the motor delivery line from the pump, fast action is achieved and possible damage to machine, workpiece or tool due to an overload is avoided or reduced.

Title: Electrochemical treatment plant - where only one spray rinsing station is required in row of treatment tanks contg. different liquids
Inventor: STEINS HELMUT
IPC: C25D21/08
Filed: 1979-03-22
Abstract: The plant consists of a raw of treatment tanks, but only one spray rinsing station is included in the row of tanks. A pair of overhead rails support a driven trolley carrying a hoist via which the workpieces can be lowered into each tank and into the rinsing station. On the bottom end of the hoist is a bowl mounted on a swivel and actuated by a work cylinder or other device. When the hoist lifts a workpiece out of one tank, the bowl is moved under the workpiece so drops of liq. falling off the piece cannot enter other tanks while the piece carried horizontally to the station. The plant is much simpler and of short length when only one rinsing station is used; and the bowl prevents the liq. from one tank from contaminating the liq. in another tank.

Title: Coal gasification contaminants treatment - by recycling all for thermal cracking except sulphur, fluorine and chlorine
Inventor: DEGGIM DIETMAR DIPL ING
IPC: C02F11/00
Filed: 1979-05-22
Abstract: In a system for the treatment of pollutants, specially of waste gases, vapours, effluents and slurries produced during the coal gasification, the pollutants are passed through a chemical process and thereby cracked thermally. In a coal carbonisation or gasification plant, the pollutants are recycled to the reactor, and the wash water from the gas scrubbers which contain a part of the contaminants is used as the gasification medium in the reactor. This requires only the extraction of Cl, F and S in elementary form or as cpds. from the process; all other contaminants are cracked by recycling and prevented from recurring so that their concn. is kept constant.
Patent DE-2925190-A1 (DE)
Title: Leading and trailing vehicle axle air spring pressure control - is actuated by leading air spring pressure at one side if other side fails
Inventor: DEIKE KARL-HEINZ ING GRAD
IPC: G05D16/10
Filed: 1979-06-22
Abstract: The valve controls the pressure in the air springs of a trailing axle as a function of the air spring pressure at a leading axle. This latter pressure acts on a piston (4) against a spring (5) to operate a three-way valve (18) to reduce the trailing brake pressure when the leading brake pressure drops. The trailing pressure acts on a second piston (7) against a spring (8). This piston (7) carries a valve (18) seat (20) to vent the trailing pressure and can lift the valve (18) from a seat (19) to connet leading and trailing pressure. The piston (4) has two faces (13,14) in chambers (11,12) connected to the leading brake pressures at opposite sides of the vehicle via a change-over valve piston (21) which admits the pressure of one side to both chambers (11,12) if the pressure on the other side fails.

Title: Amplifier stage with IGFET additional equalisation - applies high biassing voltage to pn-junction between drain and/or source and substrate, not causing avalanche effect
Inventor: ROESSLER BERNWARD DIPL ING
IPC: H03F3/16
Filed: 1979-09-21
Abstract: The operational point of an amplifier stage is subsequently stabilised by a process based on 2842631. The amplifier stage contains an IGFET with source, drain, channel region, an insulator and a controllable gate, and is intended for amplifying AC signals. For subsequent stabilisation of its operational point, the transistor contains a storage gate, load switchable by irradiation, between the channel region and the control gate, this storage gate being insulated on all sides. The pn-junction between the drain (D) and/or source (S) and the substrate has applied to it a high biasing voltage (Upn), however, insufficient to form an avalanche effect. To the biased drain and/or source is supplied a short-wave electromagnetic radiation (UV). This radiation can be alternately fed to an overlapping storage gate (G1) for the purpose of underdiffusion. The radiation may be of differential strength w.r.t. one of the drain and/or source regions.
