Patent DE-3308686-A1 (DE)
Title: Elastic suspension device
Inventor: NONNENMACHER GERHARD DIPL ING
IPC: F16F1/38
Filed: 1983-03-11
Abstract: The elastic suspension device has a flange (10) on which a pump (22) is mounted. Two pairs of elastic elements (11, 12; 13, 14) are arranged on opposite sides of the flange, the stiffness of which elastic elements is significantly less in the horizontal direction (A) than in the direction running at right angles thereto. The elastic elements are connected in a force-fitting manner via supporting arms (19, 20) to a second flange (21) on which the drive machine (26) for the pump is mounted. The pump (22) is connected to the annular flange (10) such that the main body noise-energising direction coincides with the horizontal direction. Since the elastic elements have less stiffness in the horizontal direction than in the vertical direction, the force produced by the weight of the pump is absorbed with adequate strength, without any disturbing slack. Optimum suppression of the body noise is thus achieved by energising from the pump side. <IMAGE>

Title: Device for the motor-driven raising and lowering of the top part of a sun-bed
Inventor: MAUERSBERGER KARL HEINZ
IPC: A61N5/06
Filed: 1983-03-21
Abstract: In a device for the motor-driven raising and lowering of the top part of an irradiation device, especially a sun-bed, a solution is to be provided which permits a motor drive and, at the same time, guarantees that the top part is automatically raised when the energy fails, especially in the case of a power failure, so that the individual using the device can easily climb off it. This is achieved in that an energy reservoir (11) whose energy can be released for raising of the top part (2) when the energy required for the motor drive (7) fails or is switched off, is loaded on motor-driven lowering of the top part (2). <IMAGE>

Title: Process for continuous manufacture of profile sections in the surface of a material
Inventor: ISLEIB HANS-GERD
IPC: B26D3/28
Filed: 1983-03-25
Abstract: Process and device for continuous manufacture of profile sections in the surface of a soft, easily deformable material (1) according to the principle of extruding the parts to be processed of the material (1) through the openings (3) of an endless, circulating cutting mask (2), the material (1) being guided between the cutting mask (2) and a transport and pressure body (4) whilst simultaneously being continuously compressed and continuously transported in its longitudinal direction. In the process the parts to be removed of the material (1) are cut off by a cutting tool (5) disposed on the inner or outer side of the cutting mask (2) and acting mechanically or thermally transversely to the direction of feed of the material (1), which cutting tool can be designed as a ribbon blade, ribbon saw, circular knife, hot wire, laser beam etc. The profile in the material (1) remains as a concave, negative shape (hollow shape). Application of the process to rubber, elastomers, flexible foams. <IMAGE>
Patent DE-3312000-A1 (DE)
Title: Control device for cycloidal propellers
Inventor: ZENDULKA ERNST
IPC: B63H1/10
Filed: 1983-04-02
Abstract: The control device essentially has a control linkage which is designed like a parallel crank drive. During adjustment of the cruising thrust rod, the control pin for the servomotor which actuates the thrust rod for the rudder positions is adjusted by this control linkage in such a way that the coupling point of cruising thrust rod and thrust rod for the rudder positions moves essentially on a rectilinear path, and in fact exactly in the direction of the piston rod of the servomotor for the cruising thrust rod. Deviations from the thrust direction during changes in cruising thrust are thereby corrected.
Patent DE-3313081-A1 (DE)
Title: Combined agitation, aeration and aspiration system for the mass culture of microorganisms, cell cultures and the like
Inventor: POHL PETER PROF DR
IPC: C12M1/06
Filed: 1983-04-12
Abstract: This invention provides a solution to three technical problems important in the mass culture (in fermenters) of microorganisms such as bacteria, fungi and microalgae as well as of cell cultures, namely aeration, homogeneous suspension and economic harvesting of the organisms. The blowing in of air through aeration chambers in the side arms of a rotating T-shaped agitator results in the microorganisms being aerated and simultaneously maintained in completely homogeneous suspension. The harvesting takes place with great saving of liquid and thus very economically: the agitator is initially stopped for some time and the aeration is also switched off. This leads to the microorganisms settling out on the base of the fermenter. They are then, while the agitator rotates very slowly again, aspirated through aspiration chambers in the side arms of the agitator as a very dense suspension and with only little liquid nutrient medium.

Title: Apparatus for holing roadways
Inventor: MAASS KARL-JOSEF
IPC: E21D9/00
Filed: 1983-09-20
Abstract: During the holing of roadways in underground mining and tunnelling, an apparatus is used which is arranged partly in the back-ripped roadway and partly in the roadway still to be holed. Both sections, formed by the working platform on the one hand and by a ripping tunnel on the other hand, can be moved and displaced independently of one another. The ripping tunnel consists of individual segments which can be rigidly connected to one another. In particular, joints which can be made rigid are provided here, the rigid connection being obtained, for example, by limit plates which can be inserted and are to be locked. Another possibility is to use radial-tooth connections which are rendered operative or inoperative via screw bolts. <IMAGE>

Title: Fluid-damped rubber spring
Inventor: WOLF FRANZ-JOSEF
IPC: F16F1/376
Filed: 1984-04-17
Abstract: The fluid-damped rubber spring for supporting oscillating masses, in particular for supporting the engine in motor vehicle construction, consists of a supporting plate, a bearing plate, a rubber spring element between the supporting plate and the bearing plate, in which element is formed a fluid-filled damper chamber, an overflow chamber closed off by a deformable diaphragm and an at least essentially non-deformable wall which separates the damper chamber and the overflow chamber from one another and in which there is formed at least one restriction orifice which connects the damper chamber to the overflow chamber. The hardening of the spring and damping characteristics with increasing dynamic loading, which is typical of such rubber springs, is cancelled out in such a spring by virtue of the fact that the rubber spring element has at least essentially the form of a one-sheet hyperboloid of revolution.

Title: Device for pivoting the yarn guides on ring spinning and ring twisting machines
Inventor: GEISLER HARALD
IPC: D01H9/14
Filed: 1984-04-28
Abstract: The invention relates to a device for pivoting the yarn guides on ring spinning and ring twisting machines, the yarn guides being pivotable into the spinning position or balloon position by means of a geared motor and being arranged, in the spinning position and the balloon position, in a stationary manner on the yarn-guide shaft and, in the spinning position, centred via spindles provided with a spindle attachment.

This object is achieved in that the centre of gravity (7) of the yarn guides (3) is located approximately at half the stroke height (8) between the spinning position (5) and balloon position (6) - Figure -. The invention achieves the technical effect that, even in the balloon position, the centred arrangement of the yarn guides via the spindles is ensured.
