Title: Prepn. of blood samples for microscopic examination - by smearing several drops on slide, drying and staining
Inventor: BLANK HANNELORE
IPC: G01N1/30
Filed: 1977-03-25
Abstract: Several drops of blood are extracted from a finger and placed on a clean, dry microscope slide. With the edge of another slide they are spread to and fro to make thicker smears than usual to cover at least three quarters of the surface of the slide. The smears are then allowed to dry in the air. They are fixed with alcohol and after drying treated for one minute with the acid component of a stain. They are then washed with clear, cold water and the base component of the stain is applied for three seconds, followed by further washing and drying. A drop of immersion oil is applied to the dried stained blood smear and the sample is then examined at a magnification of 500.

Title: Pipe joint for petroleum industry - uses liq. adhesive to seal gap between mating tapered surfaces
Inventor: BUTLER MAJOR GENE
IPC: F16L13/10
Filed: 1978-03-01

Title: Wind powered generator with variable pitch blades - has swivel point of blades offset from aerodynamic centre to balance forces
Inventor: SPRANG PETER DIPL ING
IPC: F03D7/02
Filed: 1978-06-08

Title: Electric motor driven car door locking mechanism - has draw lever turning to move lever at slot end, activating bolt
Inventor: WACKER HERMANN
IPC: E05B77/48
Filed: 1978-06-24
Abstract: The key-operated switch is used for an electric motor driven doro locking system for motor vehicles, as in the main patent. The motors are built into the side of the coachwork. The electric motor concerned moves a draw lever when partly turned, via a gear with a drive crank. Across a slot guideway this lever moves a swivel lever, held rotatably under spring force at the slot end, to activate the bolt. With premature stopping against the bolt, the motor carries out its part turn. The rotary bearing is displaced against spring action in the guideway. Security is enhanced, and motor damage in the event of doors being incompletely closed is prevented.

Title: Quadratic force detector with rotationally symmetric characteristics - uses two opposing coils in diode bridge
Inventor: MIRAHMADI AMIN DIPL ING
IPC: G01F1/28
Filed: 1978-09-27
Abstract: The quadratic force detector has a rotationally symmetric characteristic. One coil is connected to a moving lever arm and a second coil is wound around the central limb of a fixed electromagnet. The first coil is connected in series with a diode bridge network and the second coil lies between the bridge corners which form the second diagonal. When the lever moves a position detector drives a regulator which injects a current into the bridge circuit. This generates a compensating force between the two coils whose magnitude is proportional to the square of the current and whose sign is determined by the current direction in the series coil. This can provide a directly proportional measure of the volume flow past a measuring orifice using a pressure sensor disc with a balancing beam connected to the regulator.
