Title: Vertical oil filter for internal combustion engine - has non return values to prevent by=passing at brief pressure pulsations
Inventor: MATSUBARA MASAO
IPC: B01D35/153
Filed: 1980-05-02
Abstract: Filter comprises a vertical, cylindrical casing with external ribs, a bottom screw opening for an attachment, an oil outlet cylinder (II) along the vertical axis of the vessel and a filter of rolled fibrous material between the central cylinder and the inner wall of the vessel. Sieves at top and bottom contain the filter material and a central opening is surrounded by a number of inlets (I) at the top. A non-return valve is connected to (I) via a plate which prevents vortex formation. A connecting sleeve is screwed onto (II) and has, along its cylindrical wall, a number of vent apertures which can be opened and closed by moving a slide ring surrounding this sleeve in a vertical direction. A non-return valve at the bottom end of this connecting sleeve prevents flow-back of oil and serves as a pressure regulator. The non-return valves prevent very high pulsations in the oil filter caused by the motion of the engine; such pulsations can result in bypassing of the filter and thus in incomplete filtering of the oil. In addn., prodn. of foam is reduced.

Title: Nozzles for spraying fluid on powder in mixing drum - spaced at intervals along drum axis, overcome wetting and dust problems
Inventor: EIPPER GUNTER DIPL ING
IPC: B01F29/63
Filed: 1980-05-22
Abstract: Fluid from an external supply delivered to the centre of a rotating drum for mixing powders with liq. is sprayed from nozzles arranged along the central longitudinal axis of the drum. The nozzles are supported on a pipe in the upper half of the drum and can be directed so that the spray impinges on the mixture surface at right angles to provide max. wetting effect. The main nozzle in each sprayer may be supplied from the interior tube of a concentric pair, with the outer tube having smaller nozzles connected to a separate source, e.g. of gas for fluidising the mixer drum contents. In the mixing of colouring materials and dispersants in water, the evolution of dust from very fine particles and the difficulties in wetting such fine particles are overcome by spraying with oil to agglomerate the particles. With the present device the applied fluid, e.g. oil, is uniformly and economically applied, using only a fraction of the amt. with known appts. Specification printed 25.2.82.

Title: Clamping device for thin sheets - consists of turntable roller and lever with cam face for pressing sheet against roller
Inventor: MEIER JOHANN
IPC: F16B2/18
Filed: 1980-07-25
Abstract: The device has clamping elements, consisting of a turnable roller (1) and a relatively pivotable eccentric lever. In initial position, the outer surface (4) of the lever, which is eccentric relative to its pivot axis (3), engages on the roller, or is at a distance to it, which is less than the thickness of the sheet to be clamped. When a sheet is inserted, automatic pivoting of the lever against a return torque takes place, so that its clamping surface (4) is spaced from the roller. When a traction force is applied to the sheet opposite to the direction of insertion, a torque acts onto the lever, which may have a serrated clamping face.
Patent DE-3034099-A1 (DE)
Inventor: BERNHARDT LUTZ DR
IPC: G06V30/10
Filed: 1980-09-10
Abstract: A method and circuit for segmentation of characters from a serially-read character sequence scans the character sequence in a column-by-column format and intermediately stores portions or cut-outs of the scanned characters in the form of an image pattern matrix associated with each portion. The image patterns are thus offset by one column with respect to one another. For each image pattern, a coefficient memory stores several coefficients associated to the specific image pattern which are read out and summed to form a margin value which is associated with the average column of the individual image pattern matrix. A maximum value which occurs in the series of continuously formed margin values signifies a separating point for the associated column.

Title: Loudspeaker assembly with resonator - has cylindrical resonator body between coil actuator and membrane
Inventor: RINKOWSKI ALFRED
IPC: H04R1/28
Filed: 1980-10-02
Abstract: The electromagnetic exciter coil assembly and housing of a loudspeaker are designed to minimise interactive resonance effects leading to distortion affecting quality of reproduction. Natural frequency vibrations of the electromagnet have to be isolated from the membrane of the loudspeaker. This requires that the resonant frequency of the membrane should be brought into phase with the threshold frequency of the electromagnetic coil. A cylinder of an elastomer with a metal insert is used between the membrane and actuator to provide the required characteristic.

Title: Six-part hot room with an oval plan for sanitary purposes
Inventor: ROSEWICZ HORST DIPL CHEM DR
IPC: A61H35/00
Filed: 1981-01-31
Abstract: The invention relates to a foldable sauna offering the advantages of       1) a stretched-out seated position;   2) easy accessibility;   3) adequate temperature control.   Re 1): the stretched-out seated position is made possible by an oval shape of the room body. This, in turn, is achieved by surrounding an elliptic floor grid with a segmented frame. The latter can be explained most easily as being a blind whose rolling axis extends at right angles to the plane of the floor grid at the elliptic periphery. Re 2): the room body can be easily entered and left due to a divisible upper floor (Fig. 1). Re 3): generation of a temperature (up to 95 DEG C) adequate for medical applications (sauna) is achieved by     a) the use of a heat-resistant plastic without any plasticiser, b) coating the inner side with a metal serving as a heat reflector,    c) outside insulation with a heat-resistant foamed sheet, d) a fan heater which has a circulation device and is located in the interior.   <IMAGE>

Title: Hydraulic motor with 100% built-in capacity
Inventor: BERTRAMS JOSEF
IPC: F03C1/06
Filed: 1981-08-19
Abstract: In the subject of the application the vanes are positively controlled and are drawn into the rotor in the high-pressure area. As a result the hydraulic medium which has got behind the vanes on the intake side of the rotor emerges and fills the slot created on the head side of the vane and on the circumference of the rotor. The utilisation of the capacity is thereby introduced into the high-pressure area by the rotor and is composed of the quantity of liquid hydraulic medium thus carried along and the built-in capacity and results in 100% built-in capacity. Due to the hydraulic medium fed in under pressure (from outside), which compensates for the slip, fluid pressure is then imparted to the pressure area or areas, as a result of which the rotor rotates and develops a torque of a magnitude resulting from the fluid pressure times the pressure area minus friction. One or more pressure areas are produced according to the number of intake and pressure zones provided.
