Patent DE-3921582-A1 (DE)
Title: Device for singling out and removing sheets from stack - has slider pressing against back of stack with permanent preset force
Inventor: SCHLOTTKE KARL-HEINZ
IPC: B63H3/10
Filed: 1989-06-30
Abstract: The device for removing single sheets from a stack includes a slider (17) which adjoins the back of the stack to move it towards the sheet removal means. This slider (17) acts with a permanent preset contact pressure force against the back of the stack. The contact pressure can be changed in dependence on the height of the stack by suitable means (22, 24). As the stack height decreases so the contact pressure of the slider on the back of the stack decreases. The slider can be mounted on a pendulum arm (21) which is swivel mounted above the stack pick up (2). ADVANTAGE - The pressure is always sufficient to move the stack without compacting the sheets as the number of sheets vary.

Title: Electromagnetically efficient machine with transverse flux path - has high density airgap flux, low magnetic leakage, fast commutation properties and superconducting potential
Inventor: WEH HERBERT PROF DR ING
IPC: H02K19/10
Filed: 1989-08-19
Abstract: A rotating electrical machine with stator (J) and rotor (R) elements has polereces in which a magnetic field at right angles to the direction of movement between rotor and stator is developed. The associated excitation is provided by separate windings, the first of which (a) is A.C. energized and the second (f) carries a constant D.C. of magnitude equal to the A.C. peak amplitude. A series of permanent magnets is disposed within the rotor for the suppression of interpolar leakage fields and the design prompts the use of superconductors under cryostatic control. USE/ADVANTAGE - Combined A.C. and D.C. fields reduce inducting of system and shorten commutation time, enabling higher peripheral speeds with increased power output. Improved efficiency as result of reduced copper, iron and leakage losses. Output for unit volume is increased. Principes equally appliance to linear induction motor.

Title: Hydraulic circuit with hydraulic accumulator - incorporates valve which can be held open when required
Inventor: STUMPF ROBERT
IPC: B62D5/07
Filed: 1989-10-07
Abstract: The hydraulic circuit consists of a pump (3), which supplies hydraulic fluid to several items of hydraulic equipment (V1) to (Vn), (V(n+1)) and (V(n+2)). The hydraulic circuit is fitted with a hydraulic accumulator (1) and a non-return valve (9) is fitted in the pipe line (2). The non-return valve (9) is so designed that it can, when required, be held in the open position. Under normal operating pressure, the non-return valve (9) is allowed to close t  so that hydraulic fluid from the hydraulic accumulator (1) cannot flow back through the pipe (2). When operating below normal pressure the non-return valve (9) is held open to allow hydraulic fluid to flow from the accumulator (1) to the equipment. USE - Hydraulic circuit in vehicle.

Title: Determn. of spatial distribution of metabolites in tissue samples - by bio-luminescence, using conc. viscous soln. of luciferase and counting photons in unit area
Inventor: MUELLER-KLIESER WOLFGANG PROF
IPC: C12Q1/66
Filed: 1989-10-28
Abstract: Determn. of the spatial distribution of metabolites in tissue samples by bioluminescence, by treating the sample with luciferase soln. and opt. another enzyme soln., and counting the photons/unit of surface of the tissue sample, using a photon-counter and a video camera, an enzyme soln. with high luciferase concn. and high viscosity is used. The enzyme soln. has luciferase concn. of 0.1-20 (8-12) mU/ml and opt. a gel matrix; it may contain gelatine and/or polyvinylpyrrolidone. The enzyme soln. applied in frozen form, esp. as a thin layer, to the tissue sample, and the temp. is then allowed to rise to just above the dew point of the sandwich so formed. By means of an image processor/integrator for the points of the image surface, with variable time constant for the photon enumeration, a definite time interval is singled out  during the whole course of the reaction. USE/ADVANTAGE - The method can be used to determine distribution of metabolitesa, e.g. glucose, lactate and adenosine triphosphate (ATP) in tumour tissues. Cross-diffusion or inter-flowing of enzymes and substances to be determined is avoided, as is diffusion of light by gas bubbles in the enzyme layer. The photon-emitting chemical reactions are much more rapid, giving quicker tissue analysis.

Title: Decorative coatings formation on carrier with HF activated adhesive - carrier is metal plate acting as earth electrode and other electrode is punch applying decorative layer
Inventor: PRECHTL GEORG
IPC: B29C63/00
Filed: 1990-01-26
