Patent DE-2610579-A1 (DE)
Title: Solenoid valve for electromagnetic brakes - has coil operating several individual valves fitted in housing side by side
Inventor: PIESCHE GUENTER ING GRAD
IPC: H01F7/16
Filed: 1976-03-13
Abstract: The composite solenoid valve operates several functions in a brake system by a single coil which can be energized in two stages. When without current the individual valves are in such positions that the front wheel and rear wheel brake cylinders are connected with the master cylinder, and the low pressure chamber is closed by an individual valve. The rear wheel brake cylinders then receive pressure in a delayed action due to the valve which in this case operates as a non return valve. In the case of an impending wheel blocking condition, the coil receives current from a sensor-activated electronic instrument and becomes energised up to the first stage. The armature is drawn inwards and operates valves in an opening or closing movement. During the closing a plug lifts off against the force of springs.

Title: Enzymes sepn. from cells after solubilisation - by partition in multiphase systems contg. polymers
Inventor: KULA MARIA-REGINA DIPL CHEM DR
IPC: C12N9/44
Filed: 1976-04-14
Abstract: Sepn. of enzymes from cell (residues) is carried out by solubilising the enzyme and partitioning the enzyme, together with insoluble cell materials and cell fluid, between the various phases of an aq. multiphase system contg. either (a) >=1 high-mol. -wt. cpd. (e.g. an opt. substd. polyol; polyether, polyester, polyvinylpyrrolidone or polys saccharide) and at >=1 inorganic salt, or (b) >=2 high-mol. wt. cpds. The phases are then sepd., and the enzyme is sepd. from the high-mol. -wt. cpd. and opt. isolated. The process can be used to separate, e.g. aminoacyl t-RNA synthetases from E. coli, maltose from brewer's yeast, or pullulanase from Klebsiella pneumoniae. It is not necessary to remove the cell fluid before the multiphase partition treatment.

Title: Combined half-tone mask for four-colour printing - has single mask divided into four parts with rasters at different angles to permit single exposure and development
Inventor: HAN YANG WOO
IPC: G03F5/14
Filed: 1976-10-04
Abstract: A combined half tone contact grid mask for the simultaneous exposure and production of four-colour half tone positives, has a main body of square or rectangular form with a vertical and a horizontal line intersecting at right angles at the centre of the mask so as to divide it into four equal square or rectangular sections.

Patent DE-2723667-A1 (DE)
Inventor: GOECKE DIETER DR ING DR
IPC: H04Q3/62
Filed: 1977-05-25
Abstract: A correctly timed handling of waiting request events is to be ensured even when various types of requests of equally-authorised access points are present. For this purpose, the request event is only stored when all connection path facilities (AVSx, HS1, HS2) are busy in connection with the address of the access point (N1, N2) outputting the request in vain and with the type of request. The storing is effected in the order of the determination of requests. The handling is effected not only in the order of arrival but also in the order of priority of the type of request. As a result, equally-authorised request events can also be forwarded at different speed in dependence on the idle and busy state of requested connection path facilities depending on their type. <IMAGE>

Title: Battery powered earthquake alarm - uses weighted chain as switch actuator for electric bell and includes mercury switch
Inventor: OBERMANN PETER
IPC: G01V1/00
Filed: 1977-07-06
Abstract: The earthquake alarm comprises a box housing made of insulating material (2) containing an electric bell or gong powered by four dry cells (14a-d).

Title: Energy utilising station powered by natural gas - has two injection pumps compressing gas for recycling between output and heat exchanger
IPC: F01K19/08
Filed: 1977-09-15
Abstract: Natural gas from a supply at its original pressure passes through two injection pumps in series. It draws in gas from a low pressure supply and compresses it thereby raising its temperature. The combined stream of gas passes through a heat exchanger and is then taken to an appliance using the gas. Part of this stream is drawn off and has its pressure reduced in an expansion valve. This expanded stream forms the low pressure supply to the injection pumps. The heat exchanger provides an input to a thermal store. This provides a heat source for a local space heating system.
