Title: Process for the preparation of an elastomer material which cures by means of water at room temperature
Inventor: GOMULKA GRZEGORZ
IPC: C08K5/521
Filed: 1988-10-21
Abstract: A process for the preparation of an elastomer material which cures by means of water at room temperature is intended to provide a solution by means of which both processing is simplified and the corresponding product has better mechanical properties, higher abrasion resistance and the like. This is achieved by mixing liquid polymers with plasticisers and/or emulsifiers and causing this system to cure at ambient temperature by subsequent addition of water.
Patent DE-3838313-A1 (DE)
Inventor: BETHKENHAGEN JUERGEN
IPC: G01N15/05
Filed: 1988-11-11
Abstract: A device for measuring the sedimentation rate of blood particles (BSR) of a blood sample (2) which has been rendered incapable of clotting provides for the use of an extraction syringe (1). In order to create a closed system, the sedimentation tube (9) also forms at the same time the syringe piston rod of this extraction syringe (1). In this case, the sedimentation tube (9) is surrounded, in the non- reading region, by a sleeve (11), which is sealed off at its lower end by a shaped-on projection which exhibits a central aperture (14). In this case, the sedimentation tube (9) is insertable into the sleeve (11) as far as this projection. In order to prevent the blood sample (2) from flowing out during the measurement, a closure element is associated with the aperture (14). <IMAGE>

Title: Protective sleeve for the cannula of infusion syringes, blood-withdrawing instruments or suchlike devices
Inventor: BADER MOHANDES
IPC: A61M5/32
Filed: 1988-12-14
Abstract: Protective sleeve (10) for the cannula (18) of injection syringes, blood-withdrawing instruments or suchlike devices which each have a barrel (17) for the reception of a liquid, on one end of which there can be fixed the cannula (18), especially inside a cylindrical cannula attachment (19) formed at this end, the protective sleeve (10) being attachable so as to be axially sliding on the barrel (17) of the syringe or the like, and after injection or withdrawal of blood being displaceable into a position in which it completely covers the cannula (18). Inside the protective sleeve (10) and inside the sleeve body (11) allocated thereto, a locking element (12) is positioned on the end opposite the attachment end. After attachment of the protective sleeve (10) on the barrel (17) of the syringe or the like, this locking element can be coupled to the cannula end of the barrel, especially to a cannula attachment (19) formed there, such that it permits displacement of the protective sleeve (10) into the cannula-covering position (Fig. 4), whereas it blocks displacement in the opposite direction. <IMAGE>
Patent DE-3843613-A1 (DE)
Title: Wheel suspension of a steerable vehicle wheel
Inventor: HAJTO JENOE
IPC: B60G15/06
Filed: 1988-12-23
Abstract: In a known wheel suspension a self-aligning torque independent of the axle parameters is produced by a spring element, which is directly supported on the wheel carrier. This has the disadvantage that a part of the spring force generated by the spring element acts as lateral force on the wheel, which has an unfavourable influence on the steering behaviour and the force required for steering. The new wheel suspension is intended to avoid these disadvantages. The said aim is achieved in that the spring element (40) is supported at its one end (41) by way of an articulation (44) on a transverse link element (10; 20), the articulation (44) lying outside a swivel axis (82) passing through the inner and outer joint (26, 36; 24, 34) of the transverse link element (10, 20). At the same time the joints (26, 36; 24, 34) are designed so that in the steering process the transverse link element (10; 20) rotates about the swivel axis (82), as a result of which the articulation (44) moves on a circular path and in so doing raises the vehicle by way of the spring element. The wheel suspension can be used for double-wishbone axles. <IMAGE>

Title: Process and apparatus for reducing the foam volume above a liquid in a vessel
Inventor: KULL PETER DIPL ING
IPC: C10M171/00
Filed: 1989-01-05
Abstract: In order to reduce the foam volume in a vessel (11) containing a liquid having a tendency to foam formation, in particular an aqueous emulsion of a release agent, air is introduced into the liquid beneath the surface (27) of the liquid in the vessel (11), which air ascends in the liquid in the form of bubbles (73). When the bubbles (73) reach the liquid surface (27), they burst and thus destroy some of the foam (74). <IMAGE>

Title: Monitoring data in individual cache memories - checking cache regions for hits or misses or each read access to enable data consistency to be maintained
Inventor: HAGGENMILLER ALEX DIPL ING
IPC: G06F12/0831
Filed: 1989-05-30
Abstract: A cache memory (CACHE) region is checked for a hit (HIT) or a miss (MISS) for each read access.  If a miss is detected a busy signal (MCBUSY) delays processing of the next instruction. A signal (DI) for the requesting processor unit derived from the busy signal occurring after each second or further read access invalidates the data read during the first or preceding access.  It causes a jump to an interrupt routine which can restart the whole read operation. USE/ADVANTAGE - For monitoring data provided to individual processor cache memories from working memory, enabling maintenance of data consistency.

Title: Monitoring function of turbogenerator rectifier - indirectly sensing commutation performance and analytically locating individual faults on rotary rectifiers
Inventor: GRUENEWALD PETER
IPC: H02H7/06
Filed: 1989-06-02
Abstract: A circuit, supervising the performance of multiple rotating rectifiers (RG), supplies a turbogenerator (1) and samples the HF field which attends commutation by means of a probe (2). Amplification and analysis of the resulting signals by analyser (3) enables quantification of the amplitude and frequency spectrum of each commutation impulse which is registered by fault indicator unit (12) for possible shut-down of the system via a unit (8). Additional modules (4,7,9,10,11,13) enable signal integration over several power cycles for improved accuracy and comparison with stored norms in association with angular/phase data inputs (5,6). USE/ADVANTAGE - Does not require hard wired signal input from rectifiers. Is applicable to all sizes of turbogenerator up to largest ratings in service.

Title: Fine working or micro-finishing method
Inventor: SCHMITZ HEINZ GUENTER
IPC: B24B5/22
Filed: 1989-09-12
Abstract: The reaction force exerted on the tool by the workpiece as the sum of the counterforces of all normal force components of the contact pressure acting on the cutting edges is measured continuously and the contact pressure is readjusted stepwise to a predetermined maximum limiting value at which optimum material removal takes place. Adjustments are always made when due to material removal the contact pressure has sunk to a predetermined minimum limiting value. The gap is adjusted between a maximum and a minimum value, whereby a corridor of contact pressure is created alternating between two limits, whereby, in order to maintain the limits, the infeeding of the tool towards or away from the workpiece is adjusted corresponding to the measurement of the reaction force.

Title: Washing machine friction damper - has friction lining on push rod with free axial movement and higher friction coefft. against housing than against push rod
Inventor: HECHT JOSEF DIPL ING
IPC: D06F37/20
Filed: 1990-05-03
Abstract: The friction damper, esp. for a washing machine or spin drier, has a friction lining (8) fitted between two axialy displaced limit stops (9, 10) to give a free movement (F) between them. The friction coefficient (R1) between the friction lining (8) and the guide housing (2) is greater than the friction coefficient (R2) between the friction lining (8) and the push rod (1). The lower friction coefficient (R2) is effective only at the oscillating amplitudes within the free movement (F). On oscillating amplitudes which exceed the free movement (F), the larger friction coefficient (R1) comes into effect. ADVANTAGE - The mechanism gives a generally true running for the washing machine or spin drier, with the lowest possible damping. This reduces noise levels within a simple structure.
