Title: Flowmeter for motor vehicle fuel supply - uses damping piston eliminating errors arising from vehicle motion
Inventor: ROGG WERNER DIPL PHYS
IPC: G01F1/24
Filed: 1980-03-18
Abstract: The flow of gas or liq. raises a float (8-10) inside the flowmeter's casing. The float is attached via a rod (7) to a weight (2) made of ferromagnetic material. The weight is situated in the field produced by an induction coil. A return spring (4) is located between the weight and a collar fixed to the casing and acts against the action of the fluid flow on the float. A damping piston (5) is situated between the collar (6) and the return spring (4) and slides along the rod (7). The effective cross-sections of the piston and the float are roughly equal. The fluid (12) enters the casing radially between the float and the piston. The return spring may be helical and is designed so that the force it produces when the float is raised is equal to the force due to the weight of the damping piston. The weight and the piston have means of centering the return spring and one and/or both may be pot-shaped. The piston compensates for any errors in flow measurement due to movement of the vehicle.

Title: Rotating cube
Inventor: OBERMAIER ANTON GEORG DIPL KFM
IPC: A63F9/08
Filed: 1981-03-23
Abstract: In this rotating cube (10), which represents a three-dimensional puzzle, small cubes which, depending on their position, form corner pieces, edge pieces or central pieces, are connected to each other in such a way that the small cubes which lie in one plane (12, 14, 16, 18, 20) can be rotated together relative to the other small cubes. The connection between the small cubes is via tongues and grooves, arcuate pieces of grooves or tongues in each case being provided on the lateral surfaces of the small cubes which are not visible from outside and, when they lie in one plane, always combining to form a continuous annular groove (50, 54) or annular tongues (62, 88). Since no rigid axis-star is provided on the rotating cube, rotating cubes can be provided whose lateral surfaces (12, 20) are composed of from four to thirty-six small cubes, it being unimportant whether the number of small cubes per lateral surface is even or odd. Since the small cubes lying in one plane are connected to the small cubes lying in the plane parallel thereto, in the form of a rotating collar, the interior of the rotating cube is hollow when there are nine and twenty-five small cubes per surface of the rotating cube. When the number of small cubes per surface of the rotating cube is even, core cubes are provided in the interior of the rotating cube. When the number of planes is even, then each small cube can be twisted relative to each other one. If the number of planes is odd, then the small cubes lying on the mutually intersecting median axes are fixed in position relative to each other. <IMAGE>

Title: Process for producing wood pulp
Inventor: LINDAHL JAI
IPC: D21B1/14
Filed: 1981-03-24
Abstract: A uniform stream of a suspension of mechanical pulp is fed, together with coarse wood residues and splinters contained therein, continuously from a grinder (1) to a cone mill (2) which has two treatment zones with a stationary part and a rotating part, in order to convert all the wood materials present in the suspension into individual fibres. At the same time, the degree of grinding of the wood pulp obtained is measured and adjusted to a desired value by controlling both the power consumption of the cone mill (2) and the degree of grinding thereof. The process can be applied to mechanical wood pulp suspensions which have been produced in normal-pressure or superpressure grinders. The wood pulp obtained has a low splinter content and superior strength properties. The power consumption is less than in known processes.

Title: Method for adaptive threshold value definition for radar signals
Inventor: BAUR KARL
IPC: G01S7/292
Filed: 1981-03-28
Abstract: In a radar installation with a surveillance zone divided into a multiplicity of sub-zones, a threshold value is defined adaptively for each sub-zone which is derived from the intensity of the echo in the vicinity of the sub-zone. To prevent strong target echoes from corrupting the threshold value setting, a first mean value is formed from the amplitude values of all the sub-zones in the immediate vicinity of the respective sub-zone under surveillance and, to define the threshold value, the only sub-zones which are used again are those whose amplitude value lies below this first mean value.

Patent DE-3117450-A1 (DE)
Title: Screen-drum apparatus
IPC: D06C7/02
Filed: 1981-05-02
Abstract: The screen-drum apparatus serves essentially for the low-tension heat treatment of continuously arriving shrinkable textile webs. As is customary, the flow passes from the outside inwards through the textile material resting in folds on the screen drum. In order to lift off the textile material from the screen-drum casing for a short time, nozzles supplied with compressed air are arranged over the working width on the inside of the screen drum and blow the textile material against a baffle plate concentrically surrounding the screen drum or against a rotating permeable endless band. It is expedient briefly to interrupt the blowing air acting from the inside outwards through the nozzles, in order thereby to increase the tumbling effect.
