Patent DE-4208980-A1 (DE)
Inventor: KRAEMER OTMAR
IPC: F15B15/14
Filed: 1992-03-20
Abstract: A hydraulic driving device has a cylinder (10), a piston (16) movable in a working chamber, a piston rod (17) that extends outwards through the cylinder head (11), a wear-resistant primary packing (19) and a leak-proof secondary packing (20). Both packings act between the cylinder head (11) and the piston rod (17). The primary packing (19) is located nearer to the working chamber that the secondary packing (20) and an oil leakage pipe (24) is arranged between the primary (12) and the secondary (20) packings. In order to improve such a hydraulic driving device, so that the cylinder (10) may be held for a long time against a load in a determined position, even when the pump (40) is switched off, a load-retaining pressure can be applied in the oil leakage pipe (24) by actuating a valve (25, 31).
Patent DE-4212613-A1 (DE)
Inventor: SCHMIDT LOTHAR-WERNER DIPL ING
IPC: F16H1/32
Filed: 1992-04-15
Abstract: A single-stage, three-gear compound mechanism developed on the basis of the laws that rule planetary gears allows a continuous wide range of speed of rotation to be obtained for all planar mechanisms according to DIN 42677, thanks to a fixed step-down or step-up ratio (i) comprised between 1.5 and 4.5 million. The attainable efficiency ( eta ) equal to or higher than 95 % is obtained as a result of the design of the splined shaft, identical to the torque summing shaft, and by the choice of a corresponding driving or driven gear with coupling pins for both disclosed variations (fig. 4 and fig. 5), with a minimal inner rolling performance. An Aditional rolling contact length is achieved thanks to the wobbling undulating movements of the inner wheel (fig. 4, no. 2), influencing the total step-down or step-up ratio. The mechanism is mostly made of highly-stressable composite material with an integrated fibre matrix by an injection moulding technique. This mechanism designed as a modular system requires only small modifications (fig. 4, no. 8) to achieve different speeds of rotation or torques within each performance class. By replacing the roller bearings by electric bearings, N  </= 5 million speed of rotation ranges are achieved. This compact and light-weight mechanism is suitable for optimal adaptation of speeds of rotation and torques, as well as for applications which require high accurancy of adjustment.

Title: Method for maximising the slip-dependent frictional force which occurs in the case of surfaces rubbing on each other under the influence of force, using a fuzzy controller
Inventor: PALM RAINER DR ING
IPC: G01M13/02
Filed: 1993-03-22
Abstract: By means of the invention, a method is described for maximising a frictional force transmitted in, for example, wheel-rail systems. In contrast to previously common methods, a variable magnitude of correction is used here. This has the advantage that, after an impressed disturbance, operation at the maximum frictional value of the frictional value curve can be achieved once again very rapidly. A further advantage is achieved by taking into account the different impression of frictional value curves in the case of different wheel-rail pairings by means of a matched selection of the membership functions of the fuzzy controller. <IMAGE>

Patent DE-4314646-A1 (DE)
Title: Pistonless internal combustion engine functioning on the injection or diesel principle
Inventor: LIPINSKI JOSEF
IPC: F02B3/06
Filed: 1993-05-04
Abstract: In addition to simple construction, the engine affords a large weight saving, quiet running and permits substantially higher speeds. The pistonless internal combustion engine comprises a pressure vessel and a plurality of combustion chambers, which are arranged in a ring around the drive shaft, connected to the pressure vessel by non-return valves and closed off on the front side by a ring with outlet openings, and a rotor. A control disc, which is provided with segmental openings and is externally driven is arranged between the combustion chambers and the rotor. Each combustion chamber is filled by way of the non-return valve with compressed air, the pressure of which is equal to the compression pressure. When the outlet opening is closed fuel is injected and ignited. Due to the rotation of the control disc the outlet opening is exposed and the highly compressed gas passes into one of the recesses of the rotor. There it is deflected and expanded. In the process a tangentially acting force is generated, which produces rotation of the rotor and the drive shaft. Due to the rotation, the outward flowing gas generates a centrifugal force, which acts on the rotor. The tangential component of this force generates an additional torque.

Title: Baking apparatus, in particular for pan-type dishes
IPC: A21B3/18
Filed: 1993-10-07
Abstract: The invention relates to a baking apparatus, in particular for pan-type dishes, with a rotating baking table (1) which has a plurality of baking places (2) arranged one behind the other in the direction of movement, each being equipped with lateral bounding elements which, together with the base (10) of the baking place (2), bound a baking mould. The lateral bounding elements (12) are arranged releaseably on the base of the baking place (2), in this case. Furthermore, means are provided to remove the bounding elements from the base (10) of the baking place (2) at least over a partial section of the rotating movement of the baking table (1). After completion of the baking process, the baked product thus lies freely accessible on the generally level base (10) of the baking place (2). In addition, it is proposed that a withdrawal device be provided for the finished baked product, which withdrawal device is arranged in the region of the baking table in which the bounding elements are removed from the base of the baking place. The withdrawal device may have at least one spatula-like pick-up element which rests on the base of the baking place at least in certain regions. On account of the rotating movement of the baking table, the spatula-like pick-up element is pushed between the baked product and the base of the baking place so that the baked product is removed from the baking place. <IMAGE>

Filed: 1993-10-21
Abstract: A pump signal addition point (K) has at least one optical pump signal generator (K1), at least one probe signal generator (K2) and at least one output gate (K3). A medium (NL) with non-negligible nonlinear optical effect has an input (NL1). Optical signals from the gate (K3) are sent to this input (NL1) via an optical connector (V). The nonlinear effect affects the phase, propagation rate, frequency polarisation or power of the coupled probe signal (PRK) which depends on the pump signal power. The ratio of the strength (WP1) of the nonlinear effect in the medium (NL) with respect to the probe signal (PRK) through a first part (PUK1) of the pump signal of given power and a first polarisation (P1) to the strength (WP2) with respect to it through a second part (PUK2) with a second orthogonal polarisation (P2) is x which is real, positive and no 1. The first parts (PU1) are damped so the effects of the output probe signal are independent of polarisation of the pump signal (PU). USE/ADVANTAGE - For optical switches, demultiplexers or signal regenerators. Provides nonlinear signal processing independently of polarisation of pump signal.
