Title: Method for applying a uniform volume of air to sensors, preferably for motor vehicles
Inventor: HOELTER HEINZ DIPL ING
IPC: G01N33/00
Filed: 1985-06-12
Abstract: It is known to use sensors for detecting gaseous pollutants and for controlling the fresh-air throttles and for switching filter appliances in motor vehicles. It is further known that the sensors used have cross-sensitivities, for example to the variability of the amount of air as inevitably occurs during the journey in the case of a conventional arrangement in the motor vehicle. In order to make the behaviour of the sensor used independent of the driving speed it is proposed, according to the invention, that the air to be measured be passed past the sensor by means of a constant reduced pressure with an upstream gas-permeable film. The appliance is characterised in that the sensor (2) is arranged in a gas-tight housing (1) which on one side is equipped with a gas-permeable film (3), the reduced-pressure connection (4) being provided in the region between the sensor (2) and the gas-permeable film (3). <IMAGE>

Title: Thrust-ring half extending beyond the centre
Inventor: SCHEUFLER ROLAND
IPC: F16C9/02
Filed: 1985-06-13
Abstract: To provide axial support for a crankshaft in a crank case, 4 half-washers are replaced by just two half-washers extending beyond the centre. The shape of the half-washer according to the invention is here ideally extended beyond its horizontal centre (M) in such a way that it can be installed, for example over the crankshaft to be supported together with the crank case cover. According to the invention, a projection (B) is formed asymmetrically on the outer circumferential surface of the half-washer and, in addition to preventing rotation in the case, this also prevents the washer together with the bearing cover from being mounted the wrong way round on the crankshaft. <IMAGE>

Title: Fixed bed body for predominantly horizontal percolation
Inventor: GRABOWSKI GUNTHER
IPC: C02F3/10
Filed: 1985-06-27
Abstract: A decisive factor for the efficiency of biological waste water purification plants is the bacterial mass to be retained in an aerated tank or pond, which bacterial mass, because of the prevailing flow conditions, is subject to continuous loss. In particular, microorganisms which multiply or grow slowly can, as a result, often participate in the degradation processes only in too small a number. The installation of vertically percolated fixed bed bodies has therefore proved optimal for the growth of these microorganisms in activated sludge plants having compressed air aeration. The present invention of a horizontally percolated, fixed bed body floating beneath the surface offers the possibility of also utilizing this modification in other aerated waste water tanks or ponds. The fixed bed body according to the invention is composed of a hollow body lying beneath the water, open crosswise, and made of plastic, which is connected to a buoyancy body included in the upper part or externally mounted. By joining together or chaining a plurality of fixed bed bodies, the waste water-filled tank or pond profile, in the horizontal direction of flow, can be completely or partially covered or completely covered only in the projected area. As a result, a continuous forced contact of the substances contained in the waste water with the sessile microorganisms is induced. Because of the cavity formation in the fixed bed body, a free sludge discharge downwards is ensured, so ... Original abstract incomplete.

Title: Method and apparatus for thread-length measurement
Inventor: STUTZ HANSRUEDI
IPC: G01B11/08
Filed: 1985-08-20
Abstract: A method is indicated for length measurement on precision winding appliances, which is based on a measurement of the bobbin diameter and on determining the rotational speeds of the bobbin. The variable bobbin width and the variable pitch angle of the thread helix during the winding operation can be taken into account or a correction by the introduction of variously designed correcting cycles can be obtained. Various apparatuses for carrying out this method are indicated. Each of these apparatuses consists of a diameter-sensing device 2.0 and of a rotation-sensing device 3.0 which are both connected together with a constant-input station 5.1 or 5.2 or 5.3 to a signal-evaluation device 4.10 or 4.20 or 4.30 which, when an adjustable desired length is reached, transmits a control signal to a control device 6.0 controlling the machine functions. <IMAGE>

Title: Device for controlling the brightness of an additional brake light lamp on the rear of a motor vehicle, consisting of a cylindrical housing
Inventor: OFFEL LOTHAR
IPC: B60Q1/44
Filed: 1985-11-09
Abstract: A cylindrical housing (2) is installed in the brake circuit, brake line (1) of a motor vehicle so that in the event of a braking process the excess pressure which prevails in the brake line also acts on the piston (3). Depending on the braking force, the piston (3) with the toothed rack (4+5) is thus set in motion and the current collector (8) on the light controller (9) is made to execute a circular movement by means of the axle (7) or the gear wheel (6). The greater the braking force which is exerted, the greater the excess pressure in the brake line (1) and on the piston (3) and the greater is also the circular movement of the current collector (8) on the light controller (9), the greater is also the voltage for the additional brake lamp, and the brighter (up to 55 Watts) is also the light of the brake lamp but the shorter is the braking path. The compression spring (11) ensures that the necessary counterpressure is exerted on the toothed rack (4+5) and thus also on the piston (3). The holding screw (13) is simultaneously the clamping screw for the compression spring (11). The braking force and the braking path and the brightness of the additional brake light lamp are always identical, the greater the braking force, the brighter the braking light, the shorter the braking path. The smaller the braking force, the weaker the braking light, the longer the braking path. No brake process, no brake light.   <IMAGE>

Title: Cutter mounting for the cutter head of a wood-chipping machine
IPC: B27L11/00
Filed: 1986-01-14
Abstract: The invention relates to a cutter mounting for the cutter head of a wood-chipping machine according to DE-P 3437688, in which the cutter remains firmly connected to its adjustably arranged cutter breastplate even during regrinding and even if the regrinding width required considerably exceeds the normal dimension as a result of the influence of foreign bodies. What is considered essential is that the chip discharge strip, which covers the cutter breastplate, is integrated into the centrifugal wedge, resulting in considerable savings in the production of the clamping system and improved operational reliability. In this arrangement, the centrifugal wedge can be locked, in the working position, against the cutter block or the cutter breastplate.

Title: Cutting tool for machining a rotating workpiece
Inventor: KRAUSS HELMUT WILLY DIPL ING
IPC: B23B27/00
Filed: 1986-04-11
Abstract: A cutting tool (10) for machining a rotating workpiece is described, comprising a cutting face (12) and a rear face (14) which enclose a wedge angle (k) with one another and form a cutting edge (16). The contour of the cutting edge (16) corresponds in the longitudinal direction to the axial profile of the workpiece to be machined. The cutting face (12) encloses a rake angle (s) with a reference plane (18) running through the cutting edge (16). The rear face (14) encloses a clearance angle (f) with a plane (20) which is perpendicular to the reference plane (18) and runs through the cutting edge (16). The rake angle (s) changes in the longitudinal direction of the cutting edge (16). Likewise, the cutting edge (16) can be inclined with regard to the axis of rotation of the workpiece to be machined. In addition, the rake angle (s) can be dependent upon the respective radius of the profile of the workpiece to be machined.   <IMAGE>

Title: Load-bearing structure for ceiling panels of a counter-ceiling
Inventor: MUELLER ROBERT
IPC: E04B9/22
Filed: 1986-07-04
Abstract: The ceiling panels (12) of the counter-ceiling of the load-bearing structure can be connected, by means of clamping elements (13), to load-bearing members (11) on the basic ceiling (10) by clipping on. The clamping elements (13), which are cast from a high-polymeric material and can be supported on longitudinal flanges (11b) of the load-bearing members (11) via lugs (13c), are fastened on the ceiling panels (12). The identical clamping elements (13) exhibit in each case one expansion surface (13d) which encloses an angle ( alpha ) with respect to the horizontal. In the event of a vertical clip-on movement of the ceiling panel (12), the expansion surfaces (13d) of the associated clamping elements (13) run on to the longitudinal flanges (11b) of the load-bearing members (11) and consequently briefly bend the clamping legs out backwards. Owing to such a design, it is achieved that, with favourable preconditions for a cost-effective mass production and without any greater degree of mounting outlay, even relatively heavy ceiling panels (12) can be used (Fig. 1). <IMAGE>

Title: Method and device for operation of an interplanetary flying object which is driven entirely by electrons
IPC: B64G1/40
Filed: 1986-08-14
Abstract: A flying object which is in the form of a lens, has a large area and consists of a plastic cap and an iron saucer is provided with its propulsion by solar-induced energy conversion of original mass into electrical energy whose electrons exclusively produce the force for flying movement by continuous direct effect. The method of operation is of three types: The first step comprises storing solar energy in capacitors. Energy is used for propulsion in two ways: By producing reaction in the direction of the nose of the fuselage of the flying body by converting the electrons in the capacitor into quiescent energy in a voltage-increasing manner, in order then to accelerate to the speed of light as a result of the voltage drop to the saucer, which is at a lower potential. Subsequently by firing the saucer in the direction of flight by means of electrons at the speed of light. The takeoff and landing of the flying object require the use of very large amounts of power in order to overcome the force of gravity. Weightlessness in the case of a flying object which is not conductively connected to the mass of the earth can be achieved if the magnetic flux direction which is naturally directed from the flying object to the earth is reversed. The flying object is then repelled by the earth. A precondition for this is that the flux density potential to the flying object is more powerful than the potential of the earth's attraction. The triple utilisation of the electron energy enables economical use, which is essential in the case of a flying object, of movement energy, without ballast, by finite ...
