Patent DE-3709859-A1 (DE)
Title: Pressure-medium-operated working cylinder
Inventor: HERRMANN WERNER
IPC: F15B11/024
Filed: 1987-03-25
Abstract: The invention relates to a pressure-medium-operated working cylinder in which, by activation of a working valve arrangement by means of a control unit, the piston rod of the piston acted upon on both sides can be extended or retracted by applying a positive pressure to the respective side of the piston, and in addition the control unit serves to activate a brake device for locking the piston rod in any position. Provision is made according to the invention for the two working spaces of the working cylinder which are located on both sides of the piston to be connected to one another by a transfer port in which a vent device is arranged which can be activated by the control unit, shuts off the flow through the transfer port in a first position and releases the flow through the transfer port in a second position. This ensures that, after the displacement of the piston and the piston rod by admission of pressure and subsequent locking by the brake device, the positive pressure present in the working space is reduced and a pressure balance occurs between the working spaces, as a result of which uncontrolled movement of the piston and the piston rod is eliminated upon subsequent release of the brake device.

Title: Adjacent control for hydraulically operated support assemblies
Inventor: NERLICH ERNST-GUENTER ING GRAD
IPC: E21D23/16
Filed: 1987-04-14
Abstract: The adjacent control for support assemblies 1, 2 equipped with hydraulically operable consumers has in each support assembly 1, 2 a distributor connection 4, which is connected via lines 3 to the hydraulic consumers of the same support assembly 1, 2, and a control-valve connection 7 which is line-connected to control connections of control valves 8. The distributor connection 4 of one support assembly 1 is connected via a bunched line 6 to the control-valve connection 7 of the adjacent support assembly 2 so that the control of one support assembly 1 is effected from the adjacent support assembly 2. The connections 4 and 7 are designed and arranged in such a way that the bunched line 6 runs essentially over the shortest distance between two support assemblies 1, 2 and that a bunched line 6 can alternatively be attached coming from the right or the left to the same connection 4 or 7. <IMAGE>

Title: Method and apparatus for generating a control signal dependent on the oxygen content in gases
Inventor: BOEHM HARALD DIPL CHEM DR
IPC: F02D41/14
Filed: 1987-05-08
Abstract: The invention relates to a method and an apparatus for generating a control signal dependent on the oxygen content in gases. There is provided a measuring sensor having an oxygen-ion-conducting solid electrolyte body, a reference electrode and a measuring electrode exposed to the gas. In a reference gas space (5) sealed from the atmosphere in a gastight manner and arranged on the reference electrode (4), an oxygen partial pressure is set by means of a metal/metal oxide mixture or by means of a mixture of a plurality of metal oxides. To the potential on the electrodes is added an external offset voltage, the value of which lies between 50 and 150% of the absolute value of that potential of the measuring sensor (1) which arises in the more oxygen-rich region of the characteristic curve of the measuring sensor (1) on feeding in oxygen from outside the measuring electrode (3). <IMAGE>
Patent DE-3718182-A1 (DE)
Inventor: MAIERHOFER JOHANN DIPL ING
IPC: G11C29/02
Filed: 1987-05-29
Abstract: The RAM self-check is performed using a test algorithm in the following steps: in the word-oriented storage cells, the corresponding addresses are stored consecutively in a given sequence, the stored addresses are then read and compared with the absolute addresses and the inverted addresses are coded simultaneously. The stored inverted addresses are then read in the given sequence and compared with the relevant addresses, and the addresses are again coded simultaneously. This process is then carried out in reverse. Defective functioning of the store can be detected by comparison of the addresses read from the word-oriented storage cells with the relevant addresses.

Title: Rapid process for obtaining a factor VII preparation and its use
Inventor: REUNING UTE DIPL BIOL
IPC: A61K38/00
Filed: 1987-11-30
Abstract: A process for obtaining a factor VII preparation from an aqueous solution entails the factor VII, which derives, for example, from human plasma, being adsorbed onto barium citrate and precipitated and, after elution has taken place, being enriched and concentrated by polyethylene glycol precipitation and subsequent chromatography on an anion exchanger (DEAE). Highly purified factor VII can be prepared rapidly and simply at room temperature after gel filtration and two subsequent high-resolution chromatography steps, FPLC anion exchange chromatography and FPLC hydrophobic interaction chromatography. (Within hours in contrast to days when conventional processes are used.) The isolated material shows one protein band in an SDS polyacrylamide gel stained with silver. The resulting factor VII preparation can be used to treat disturbances of blood coagulation.

Title: Insulating device
Inventor: ZIEGENBEIN BOTHO DR
IPC: F16L59/04
Filed: 1987-12-05
Abstract: The invention relates to a thermal insulating device (1) which is delimited by two housing walls (2, 3). The object of the invention is to configure the insulation device such that it exhibits a very low capacity for thermal conduction and, in addition, can be produced in a simple manner. The invention makes provision for two cylindrical housing walls (2 and 3) which are arranged concentrically. By means of a first sheathing (4), which is arranged at a defined distance around the inner housing wall (3), a first annular space (8) is formed. A second sheathing (6) is arranged at a predeterminable distance around the first sheathing (4). The space between the two sheathings (4 and 6) serves to receive the insulation material (5G). The two annular spaces (8 and 9) are filled with a material which hardens when exposed to air and effects a frictionally locking connection between the housing walls (2, 3) and the sheathings (4, 6). By means of lining a plurality of thermal insulating devices (1) in a row one against the other, a pipe system for transporting flowing media can be formed. <IMAGE>

Abstract: A description is given of a monitoring module for fluidic systems for the generation of control signals as a function of and in unequivocal assignment to different flow velocities of the fluid flowing through the system. The control signals originate from a measuring sensor in the fluid flow. This measuring sensor can be an electronic, electromechanical, thermoelectric or optoelectronic element. The signals from the measuring sensor are digitised in an electronic circuit and are stored in an electrical or mechanical store until a signal reversal occurs, that is to say, until a change in the flow direction is detected.

Abstract: An adapter having an elastic body with a first inlet for the discharge end of a steam-supplying conduit, a second inlet for the discharge end of an air-supplying pipe, a mixing chamber into which air drawn by pressurized steam which is supplied by the conduit, and an outlet which discharges the mixture of air and steam into a supply of milk to thereby foam the milk so that foamed milk can be used as a topping for regular coffee or espresso coffee. The discharge end of the pipe and/or the discharge end of the conduit is held in the respective inlet exclusively by friction to facilitate ready separation of the body of the adapter. The intake end of the air-supplying pipe carries an elastic cap with one or more channels which supply atmospheric air into the pipe when the conduit supplies pressurized steam. The cap is removed prior to cleaning of the pipe and of the body of the adapter if the body is cleaned jointly with the pipe.
