Title: Preparation of carrier-bound synthetic peptides for use as antigen in diagnostic tests and for generating a specific immune response
Inventor: WOLF HANS PROF DR DR
IPC: C07K17/02
Filed: 1987-03-23
Abstract: A method is described which permits oligopeptides to be synthesised chemically in such a way that they can be used, without being cleaved off the support used in the solid-phase synthesis, directly as antigen for detecting specific antibodies and for obtaining sera against the epitopes represented by the peptide. By using the same carrier during the synthesis and the following applications it has been possible to show, by the example of specific diagnostic tests to detect specific antibodies to Epstein-Barr virus (EBV) and human immunodeficiency virus type 1 (HIV) in human sera, the simple manipulation and the great sensitivity, with a very short time taken to prepare the test and carry it out. It was furthermore possible to show by the example of the protein p24 of HIV that the carrier-bound peptides can be used directly for obtaining specific antibodies in the animal system.

Patent DE-3710863-A1 (DE)
Title: Hydraulic, releasable non-return valve
Inventor: OLBRICH GOTTFRIED DIPL ING
IPC: F16K15/18
Filed: 1987-04-01
Abstract: A hydraulic, releasable, pilot-controlled non-return valve (10) in seat-valve type of construction is proposed whose hollow main valve body (15) and pilot-control member (29), operable by the release piston (24), permit sensitive lowering-flow control via discharge-flow feedbacks. The pilot-control valve member (29) has a damping device (54) and a pressure area (44) which produces an increasing lifting-force characteristic during increasing control-oil flow via a second choke point (39) during the opening operation. At the main valve body (15), a fine-control edge (61) arranged upstream of the sealing edge (59) produces by means of a pressure area (62) a hydraulic feedback so that the non-return valve (10) can operate in a sensitive manner over a greater stroke range. <IMAGE>

Patent DE-3721378-A1 (DE)
Title: Centrifugal pump
Inventor: ODENDAHL WILHELM
IPC: F04D1/02
Filed: 1987-06-29
Abstract: Due to the wheel friction of the impellers, at part load multi-stage centrifugal pumps have a low efficiency. The associated heating up of the medium being pumped makes the delivery pressure characteristics unstable, so that pulsations may occur. The wheel friction is substantially reduced by an arrangement of the centrifugal and centripetal impellers in pairs, so that the shortcomings are eliminated. If both types of impeller are made with the same outer diameter, the rotor can be shifted axially, thus reducing further losses, and making a closed-loop control possible that has almost the advantages of an automatic speed control, but at constant speed. The entire rotor can be withdrawn from the pump stator after opening a cover. The rotor can be balanced and installed without disassembly and re-assembly. The rotor is compact, and therefore does not reach the ranges of critical speeds. Control by axial shifting can be implemented by the partial current of the hydraulic relief device. Due to the small losses, this partial current is sufficient to dissipate the heat of friction into the intake vessel, so that a minimum-flow safeguard is not necessary.
Patent DE-3722250-A1 (DE)
Title: Mechanical three-dimensional drive for feed bars on transfer presses
Inventor: LEBBAEUS ROLF
IPC: B21D43/05
Filed: 1987-07-06
Abstract: The invention relates to a mechanical three-dimensional drive for feed bars on transfer presses, the drive being operated directly from the machine drive via separate cam mechanisms and gear cases arranged in the lateral column of the transfer press. The gear cases for the closing and stroke movement of the feed bars consist of active gear cases (1) arranged in the lateral column and passive gear cases (2) arranged on the sliding table (5), which are operatively connected to one another via releasable connection elements. The drive for the feed motion consists of the driving elements in operative connection with the passive gear cases (2), the driving pinions of these driving elements being in operative connection via a connecting pinion of the active driving elements arranged in the lateral column. For tool changing, the mechanical connections provided by the centring pins (10) between the active and passive gear cases (1, 2) are released and the tooth engagement at the connecting pinion is released by swivelling back the lever. The passive gear cases (1) with the supporting brackets (3) and the carrying and feed bars thus form a unit which is supported as a whole by the sliding table and is traversed with the latter for tool changing. <IMAGE>

Title: Retention unit for pressure aftertreatment and the like
Inventor: DEPENBROCK LOTHAR
IPC: D06B17/02
Filed: 1987-09-04
Abstract: The invention relates to a retention unit especially for the long-term treatment of running fabric webs with a high loading of liquor and is intended to provide a simple, inexpensive and space-saving retention unit of highly versatile use, by means of which widely differing treatment processes, for example pretreatment processes, such as desizing, lie-treatment and bleaching processes, but also pressure-treatment processes, can be carried out with a high loading of liquor and with the possibility of applying chemicals to the fabric web, both at low temperatures and at boiling temperatures, even for textiles sensitive to tension. For this purpose, it is proposed according to the invention to arrange, in a treatment chamber, guide plates for the fabric web which are inclined one above the other, alternately relative to one another, and on which the fabric web runs through the treatment chamber from the top downwards, with treatment liquor being supplied (Fig. 1). <IMAGE>

Title: Method for the treatment of a liquid which contains proteins of various types and other substances such as salts, sugars, mineral components, fat, vitamins, enzymes and minor components
Inventor: ROINER FRANZ PROF
IPC: B01D61/14
Filed: 1988-01-19
Abstract: The method is used for influencing the composition and the microstructure of the constituents or for splitting up into individual components of a liquid which contains proteins of different types and other substances such as salts, sugars, mineral components, fat, vitamins, enzymes and minor components. In order to be able to change the properties of the individual components in such liquids by influencing the composition and by controlling the temperature, the ionic strength or by microbial or enzymatic treatment before or during the separation treatment which is to be carried out, in order then to be able to isolate them with defined properties in maximally pure form, the liquid is divided by membrane filtration, predominantly by ultrafiltration, into a part stream with predominantly high molecular weight fractions and into another with predominantly low molecular weight fractions. The content of protein, salts and sugars and/or enzymes, vitamins, provitamins, microorganisms, minor components is specifically changed (limited or enriched) both in the part stream with the predominantly high molecular weight fractions and in the part stream with the predominantly low molecular weight fractions by further separation methods such as ion exchange, filtration, hyperfiltration, dialysis or other suitable separation methods so that in turn at least two part streams with constituents of the initial liquid in new form and with defined properties ...

Patent DE-3818647-A1 (DE)
Title: Piston/cylinder arrangement for feeding a working medium to a moving device or the like
Inventor: ZIERPKA GUENTER
IPC: F15B15/08
Filed: 1988-06-01
Abstract: A cylinder closed at both end faces and having an elongated slot accommodates a reciprocating piston which has a continuous axial recess and is closed at both end faces relative to the cylinder. A piston extension on the outside of the cylinder is firmly connected to the piston through the elongated slot in the cylinder. The piston extension has a duct for the working medium. The duct is open to the outside and is in fluidic connection with the axial recess in the piston. The elongated slot in the cylinder is closed by means of two sealing strips which extend through the piston and the piston extension and in the process are separated from one another by expanding means and are led around the fluidic connection between the duct open to the outside and the axial recess in the piston. But when the piston is moving, the sealing strips can in each case be put back behind the piston into a position sealing the elongated slot by means of closing means arranged in the axial direction between the expanding means and the end seals of the piston.
Patent DE-3822930-A1 (DE)
Title: Slubbing-blocking device for drawframes on spinning machines
Inventor: SPROED PETER
IPC: D01H13/18
Filed: 1988-07-07
Abstract: Known slubbing-blocking devices are mounted on the same holding rod as the upper-roller supporting arms, the distances between the respective slubbing-blocking device and the upper-roller supporting arm being relatively large. The free space from one upper-roller supporting arm to the other for servicing, maintenance and air-conditioning is consequently restricted considerably, especially in the case of the same mounting for the thread stop motion and for the slubbing-blocking device, because their carrier then has to extend as far as the pair of delivery rollers of the drawframe. The new slubbing-blocking device is to improve the possibilities for servicing and maintenance and to gain freedom of assembly for air-conditioning. The entire slubbing-blocking device (3) is arranged directly next to the upper-roller supporting arm (2), and all its components are located in a region which scarcely exceeds the length of the upper roller (8) of the drawframe. The slubbing-blocking device for drawframes on spinning machines is arranged on the same holding rod as the upper-roller supporting arm, it can be mounted from above and, in the event of a thread break, it lifts off the upper feed roller from its nip. <IMAGE>

Patent DE-3831733-A1 (DE)
Inventor: HANNIBAL WILHELM DIPL ING
IPC: F01L1/44
Filed: 1988-09-17
Abstract: In a reciprocating piston internal combustion engine with three inlet valves per cylinder which are individually actuated directly by cams on an inlet camshaft via pushrods and are arranged obliquely to the central cylinder axis, where the central inlet valve is at a smaller angle to the central cylinder axis than the other two, the central inlet valve begins to open later than the other two; thus the valve recess in the piston head for the valve disk of the central inlet valve becomes flatter or altogether inexistent in a high-compression internal combustion engine. Likewise, in an internal combustion engine with three outlet valves, the central outlet valve closes earlier than the other two.
