Title: Sepn. of liq. solid mixt. - fruit juice is extracted in pressing chamber with membrane walls to which external pressure or vacuum is applied
Inventor: SPOERLE HANS
IPC: A23N1/00
Filed: 1989-12-16
Abstract: Mixt. is placed in a housing and undergoes a kneading process using membranes. The membranes are first simultaneously and then alternating subjected to an external pressure, and the liq. which is pressed out is conducted away through an opening in the housing. The solid material remaining on completion of the pressing procedure is compressed by applying a vacuum to the membranes and rotating the housing, followed by a renewed simultaneous or alternating application of pressure. The membranes may alternatively be subjected to alternating pressure and vacuum so that the liq. is extracted without compressing the remaining solid material. USE/ADVANTAGE - For use in separating the phases of liquid-solid mixts. and esp. extracting fruit juice from the solid parts of the fruit. Complete recovery of the juice is achieved in a quantitatively and qualitatively optimal manner, and a continuous process is used in which ineffficiencies arising from the need to interrupt the process in order to agitate the pressed material are minimised. This is partic. advantageous in the case of the extn. of juice from grapes.

Title: Switching of timer - has detent retaining slider in set position against force of switching member
Inventor: LUNZ ALFRED GUENTER
IPC: H01H43/06
Filed: 1990-05-19
Abstract: The disc (1) operates with a number of radial slidable switching sliders (5). When the switching slider is moved from its rest position to a switching position an incline (16,19) guides the slider over a detent (15) of the disc and arrests the slider behind the detent. This blocks the slider against sliding out of position from the force of the switching member. The slider is pivoted over the detent from the switching to the rest position by manually actuating its operating knob (9). A counter detent (18) on the slider can be assigned to the detent (15) so that they form stop faces (17,20) extending roughly vertical to the radial sliding direction. ADVANTAGE - Blocked in switching position yet easily manually slidable.

Title: Pressure controller for vehicular antilock and antislip braking - includes construction in line from master cylinder to wheel brake cylinder with pressure limited by valve
Inventor: BURGDORF JOCHEN

Filed: 1990-05-25
Abstract: The hydraulic pressure in the wheel brake cylinders (5) is modulated in a pressure control mode using inlet and outlet valves (7, 6) a motor-driven pump (3) and an electronic controller. While the pressure is recovering in this mode a constriction (1) in the hydraulic line (12) connecting a pressure-limiting valve (2) to the wheel brake cylinder (5) is effective. A gradient reversal device may serve in place of the constriction. ADVANTAGE - In pressure control mode vol. flow of hydraulic fluid through constriction is independent of master cylinder (4) pressure and fluid viscosity variations.

Title: Textile fibre mixing hopper - has feed for accurate blend predetermined by calculation and regulated automatically
Inventor: FAAS JUERG
IPC: D01G13/00
Filed: 1990-08-10
Abstract: On a mixing and blending plant for textile fibres, the opened tufts are accumulated in a hopper. These are then formed into a continuous sheet by six selected methods, which employ rollers, conveyors, in conjunction, or separately, or with fixed, or adjsutable feed plates. These are adjusted to bring the supply of tufts from each side, to a central min. thickness, which is constant when the feed is driven at a certain speed. - When mixing fibres of varied provenance, type, quality, colour or other characteristic, the opened tufts of fibre are accumulated in a hopper above a conveyor. The hopper level is visible and the tufts are fed into an arrangement of rollers but are then opened by the opening roller, and fed onto the top of the conveyor, and compressed into a sheet by another conveyor, and rollers.

Title: Contactless measurer for foils or thin surface layers -  uses radiation receiver for heat radiation emitted from object when subjected to microwaves
Inventor: BAUMANN JOACHIM DIPL PHYS DR
IPC: G01B15/02
Filed: 1990-09-28
Abstract: The measurer is applied for contactlessly ascertaining the thickness and/or thermal qualities of foils and thin surface layers or coats and/or the absorption characteristics of inhomogeneous materials by means of intermittent heat conductance. A microwave generator (MG) produces microwaves (MW) intensity modulated on a time basis for directing onto the object to be measured (Mo). A radiation receiver (Se) intercepts the heat radiation emitted from the excited object.  The microwaves can be applied via a waveguide (H).  A microwave absorber cell (MA) is pref. arranged on the side of the object (Mo) facing the generator. ADVANTAGE - Copes with number of objects not allowing heating through absorption of light and optically covered layers, e.g. under water and layers contg. high water content.  No filters required to separate excitation heat radiation and emitted thermal radiation.

Title: Tyre for four-wheel drive vehicles - has construction with belt and with additional circumferential elastomer sheet to absorb shocks, stiffen sides and improve braking effect
Inventor: STUMPF HORST DIPL ING
IPC: B60C9/18
Filed: 1990-10-10
Abstract: A tyre, partic for four-wheel drive vehicles, has a toroidal body with two sidewalls and beads, a tread, a belt of at least two layers, and a radial carcas of at least one layer. The main body contains at least one embedded sheet or elastomer to provide a circumferential shock-absorbing effect and to stiffen the sides; by this means the damping effect of the tyre wrap as measured by the ratio of centre force to hysteresis force is between 0.1-0.25, and the stiffness of the wrap is at least 60000 daN. The tyre has an air-tight inner sheet (1), a carcass  (2) of at least one layer which is wrapped round the two bead cores (3), two sidewalls (4), a belt of at least two layers (5) and the profiled tread (6). The essential component of the invention is a circumferential member (at least at places) to produce shock absorption. This delays the response time between applying the brakes and their translation onto the road. Under transverse loads such as when travelling round bends, this also stiffens the tyre wrap laterally so as to keep short the time of response to steering forces. ADVANTAGE - The system enables the tyres to reduce the costs of producing controlled braking effect on four-wheel drive vehciles.
