Title: Method and device for converting a drive movement
IPC: H02K49/10
Filed: 1981-05-02
Abstract: The invention relates to a system for converting a rotating or linear drive movement into a reciprocating linear output drive movement whose direction runs essentially at right angles to the plane of the drive movement. The transmission is effected in that both the drive element (1) and the output drive element (16) are provided with permanent magnet systems (15) which interact with one another in an alternating pole pairing as a result of the movement of the drive element (1), so that the alternate attraction and repulsion forces produced result in a reciprocating movement of the output drive element (16) in the output drive direction (11). <IMAGE>

Title: Device for the dosed introduction of liquid additives to a liquid flowing under pressure
Inventor: KORNFELD JUERGEN DIPL ING
IPC: B01F25/64
Filed: 1981-08-08
Abstract: The invention relates to a device for dosed continuous admixing of a liquid (1) (in particular foam compound) to a liquid (2) (in particular fire-fighting water) flowing under pressure. The main possibility of application is in fire-fighting using foam (fire protection). The admixture comprises two sub-objectives: metering the amount of foam compound, and generating a pressure differential between foam compound and the fire-fighting water delivery stream. This is achieved, according to the invention, by part of the hydraulic energy of the liquid (2) flowing under pressure being converted, by means of a motor (preferably a turbine), into rotary-motion mechanical energy and being utilised to drive a driven machine (preferably a pump having piston-pump characteristics) which is able to raise the pressure of the liquid (1) to a pressure higher than that of the liquid (2) and at the same time meters the liquid (1) in accordance with the flow rate of the liquid (2) and the desired admixture rate. The admixture rate is achieved by varying the flow rate of the liquid (1) by means of adjusting the volumetric flow rate of a variable-delivery pump, gearing (transmission) adjustment or throttling of a branch stream.

Patent DE-3149327-A1 (DE)
Title: Rate gyro
Inventor: FISCHER PETER DIPL ING
IPC: G01C19/42
Filed: 1981-12-12
Abstract: The invention relates to a rate gyro, preferably for river boats, with a vehicle-fixed holder (12) which exhibits the reference input axis (10), a frame (24) which is rebalanced rotatably perpendicularly with respect to the input axis and elastically on the holder (12), the bearing pins (20, 22) of which form the output axis (14), a gyro rotor (15) supported rotatably on the holder (24) perpendicularly to the output axis (14) and perpendicularly to the input axis (10), the bearings of which gyro rotor form the running axis (26), and with a tap for generating a signal corresponding to the angular velocity of the holder (24) with respect to its support on the frame (12). So that the device measuring the torque does not also detect the elastic and plastic deformations in components adjoining the measuring sensor and displacements between measuring sensors and measuring device which are due to temperature differences, the following features should be used: for the elastic rebalancing of the frame (24) on the holder (12), a straight torsion rod (28), having the same axis as the output axis (14) and the inner end of which is rigidly connected to a bearing pin (22) of the frame (24) and the outer end of which is rigidly connected to the free leg of a mounting arm (30) connected to the holder (24) or formed in one piece therewith. The two ends of the torsion rod (28) carry two equally long lever arms (32, 34), the free ends of which carry the elements (36, 38) of a reaction-free tap which converts the relative movement of the lever arms (32, 34) with respect to one another into an electrical signal. <IMAGE>

Title: Device for mixing and/or homogenising a flowing product
Inventor: WULF GUENTER
IPC: B01F15/02
Filed: 1982-01-29
Abstract: The device for mixing and/or homogenising a flowing product, in particular a creme, has in the floor of a mixing container an opening for the product via which the product can flow to a homogeniser installed at the bottom on the container floor, which homogeniser has a rotor and a surrounding housing with an outlet opening for the outflow line. The passage opening on the floor of the mixing container can be closed by a closure device. As a result, the product to be mixed can be mixed by customary agitator mechanisms or the like in the mixing container without said product entering the homogeniser and contaminating it. Only after the closure device is opened can the product enter the homogeniser in order to be homogenised there and led away out of the mixing container via the outflow line. <IMAGE>
Patent DE-3205858-A1 (DE)
Inventor: MUELLER WOLFGANG DIPL ING DR
IPC: G11C11/24
Filed: 1982-02-18
Abstract: The invention provides a method of manufacturing dynamic semiconductor memory cells having random access (RAM) in accordance with the double polysilicon gate technology, with which insulation of adjacent, active regions occurs by thick oxide regions, produced according to known LOCOS technology and with which, for increasing cell capacity, a boron and arsenic ion implantation is executed into the memory region with the use of a photoresist mask. In order to increase component density, the oxide thickness in the memory region/thick oxide transistor region is reduced in a multi-stage etching sequence, axially as well as laterally, so that a gain of about 25% in memory surface and a gain of more than 10 volts in blocking bias is achieved. The inventive method is particularly useful in the production of LSI Si2 gate RAM memories.
Patent DE-3209233-A1 (DE)
Title: Device for welding metallic workpieces
Inventor: PACHE NORBERT
IPC: B23K9/08
Filed: 1982-03-13
Abstract: The invention relates to the welding of workpieces by an arc, moved magnetically along a closed weld path, with two magnet systems which surround the workpiece, are at a distance from one another in a direction perpendicular to the plane of the weld path and together produce a magnetic field which runs at least partly through the workpiece, emanates at the weld path transversely to the arc direction and is obtained in a known manner by connecting the magnet systems in opposition. So that tubular or bar-shaped workpieces of varyingly large diameter can be inserted quickly and simply into the individual magnet system, the invention proposes that the individual magnet system which bears against such a tube piece be formed from two or more parts (6, 7) which with like pole surfaces enclose the workpiece (1, 2) between them and can be removed from one another. <IMAGE>

Patent DE-3216183-A1 (DE)
Title: Method for locating gunsights
Inventor: MEUSER WILFRIED DIPL ING
IPC: G01S5/22
Filed: 1982-04-30
Abstract: In this method, a cross of four closely adjacent microphones is set up at at least two measuring sites for accoustically finding the direction of muzzle reports and determining their times of reception. In a position map, bearing vectors are entered by plotting bearing angles at positions of the measuring sites, the points of intersection of which supply gunsights and locations of dummy targets. To eliminate the dummy targets, distances of points of intersection of the bearing vectors to the measuring sites are determined with the aid of the bearing angles and the distance between the measuring sights and in each case transit time differences are determined by subtracting the distances from each point of intersection to the two measuring sites and divisions by the velocity of sound. In addition, differences of each receiving time at one measuring site with all receiving times at the other measuring site are formed. These differences are compared with the transit time differences. Correspondences supply the points of intersection which define gunsights. The method is used for reconnoitring the position of hostile artillery.

Patent DE-3225495-A1 (DE)
Title: Screw mechanism with a screw and a threaded rolling nut
Inventor: HOH KONRAD
IPC: F16H25/22
Filed: 1982-07-08
Abstract: In a screw mechanism with a screw and a threaded rolling nut, the threaded rolling nut and the thread of the screw have the same pitch and the central axis of rotation of the threaded rolling nut is offset parallel to the longitudinal axis of the screw. It is the object of the invention to provide low-friction guidance between the nut and the screw to maintain the centre-to-centre distances and ensure unhindered transmission of forces for a screw mechanism of this kind. Provided for this purpose there are, apart from the driving threaded rolling nut, two guiding threaded rolling nuts, which are each arranged in such a way that they can move freely in the axial direction within limits relative to the driving nut. The spacing of the longitudinal axis of the screw and the central axis of rotation are adjustable preferably by resilient actuating means and do not move in a planetary fashion around one another but are fixed in location. The screw runs on an internal toothing in a manner similar to a planet gear. The screw is driven. As a result, friction-free guidance is achieved and jamming, which can be caused by differing distances of advance of different nuts, is avoided.

Patent DE-3235046-A1 (DE)
Title: Fertiliser feed for mineral-fertiliser spreaders
Inventor: JAESCHKE HANS-JUERGEN DR
IPC: A01C17/00
Filed: 1982-09-22
Abstract: The invention relates to a fertiliser feed for mineral-fertiliser spreaders, in which a conveyor band conveys the fertiliser out of the container and feeds it to the spreading members. As a result of vehicle vibrations, the fertiliser has hitherto been thrown up on the conveyor band and distributed unevenly. The fertiliser stream breaks away irregularly at the throw-off edge and thus arrives at the centrifugal discs in irregular batches. The result is an unequal distribution of the fertiliser over the field. The current invention proposes that above the fertiliser stream is arranged a cover plate (13) which retains the fertiliser. The fertiliser is consequently prevented from being thrown up on the conveyor band (2). In the throw-off region at the deflecting drum (7), the cover plate (13) keeps the fertiliser stream together, thereby preventing it from breaking away at the throw-off edge (11). <IMAGE>
