Patent DE-2830460-A1 (DE)
Title: Decontaminating paper-making felt on pressurised porous roller - which expels contaminants from felt surface without causing deformation
Inventor: GARDINER FRANK J
IPC: D21F1/32
Filed: 1978-07-11
Abstract: Contaminants are removed from an absorbent felt by passing around >=90 degrees of pressurised roller, so that the gas pressure and centrifugal forces expel the contaminants. The roller may contain internal baffles to direct the pressurised gas only through the felt. Contaminants and water are rapidly and efficiently removed at high speeds and without large deformation of the felt. The felt is used to dry paper on a papermaking machine.

Patent DE-2846177-A1 (DE)
Title: Self-adjusting pneumatic suspension for lorries - has inhibit control when motor is switched off to conserve pressure
Inventor: LANG WALTER
IPC: B60G17/005
Filed: 1978-10-24
Abstract: A central compressor supplies a pressure reservoir, while each suspension element has high and low sensors to operate the airflow to and from the dampers. The system has an inhibit control to operate when the vehicle is loaded with the engine switched off. This ensures an even loading, but with no danger of emptying the reservoir. The inhibit control modulates the flow of air from the reservoir, while allowing the sensors to pass the high and low limits. It enables the vehicles to be loaded in an area in which the engine cannot be left running, with sufficient pressure left in the reservoir when the engine is switched on.
Patent DE-2847523-A1 (DE)
Title: Winding strapping around pack by rotating arm - involves arm whose length varies during, and as function of rotation
Inventor: BUETTNER HANS HUGO
IPC: B65B13/10
Filed: 1978-11-02
Abstract: The mechanism is intended for winding strapping material (43) or the like around a pack (6) by means of an arm (13) rotating about a shaft. The length of the arm varies during the winding operation, the variation being controlled synchronously with the rotational movement of the arm. The drive for the length variation may be derived from the rotational movement of the arm. This may be via a fixed central gear wheel meshing with a planet wheel on the arm which, via a crank transmission, varies the relative position of telescoping sections (16, 33) of the arm (13).

The piston strikes the face and pivots and pawl from its effective into its ineffective position. The hub has two posts which can be removed. The piston has two arms symmetric and perpendicular to the stop: each arm extends to the faces of the two pawls.

Title: Semiconductor circuit integrity analysis method - exposing chip to ionising radiation and analysing output and using various statistical methods
Inventor: SCHINDLBECK GUENTER DIPL ING
IPC: G01R31/302
Filed: 1979-04-10
Abstract: The semiconductor chip is attached to automatic testing equipment and exposed to ionising radiation. The spurious results of the test which result from the impact of the alpha particles are analysed and statistically. An uneven distribution of false results indicates a potential defect in the circuit. The technique is particularly suitable for charge coupled devices or other memory chips where the false results can be correlated with the world and bit matrix using Bernoulli or Poisson statistics. In the latter case, the number of faults per bit-line is correlated with the total number of faults and the error rate by the use of theoretical curves.

Patent DE-3006482-A1 (DE)
Inventor: SCHOEN WERNER
IPC: B07B1/20
Filed: 1980-02-21
Abstract: The disclosure concerns a rotary screening machine for moving pulp suspension through a screening slot and for separating impurities from the pulp suspension. An annular rotatable drum is surrounded by an annular porous screen basket that is spaced away to define a screening slot. Pulp suspension is delivered to one axial end of the slot and is discharged from the other axial end of the slot. Generally wedged shaped vanes, widening in the axial direction between the leading and trailing ends of the vane, are provided around the drum. The wedge defining surfaces may also be inclined with respect to a respective plane perpendicular to the axis. The space between the wedge surfaces is an open volume. A wall in that space is oriented to help create appropriate vacuum and eddy conditions behind the vane. The drum may have different zones, with the lower zone being provided with vanes and the upper zone being generally smooth. Other types of vanes or projections may be provided in the intermediate zone. Water sprayed into the slot dilutes the suspension. The configuration of the vane causes conveyance of the pulp suspension generally toward the impurities outlet and conveys the impurities to that outlet. The configuration of the vanes also causes the suspension to pulsate across the screen basket which dislodges pulp suspension fibers that otherwise might become matted on the screen.
