Patent DE-3737571-A1 (DE)
Title: Shock absorber
Inventor: SCHUMANN KLAUS
IPC: F16F9/44
Filed: 1987-11-05
Abstract: A shock absorber (damper) (1) has a piston (3) guided in a cylinder (2). This piston-cylinder system is surrounded by a bellows (9), the ends of which are leaktightly connected to the parts of the piston-cylinder system moving relative to one another. The interior (5) of the bellows (9) serves as a receptacle for the hydraulic fluid and is connected to the interior (8) of the cylinder via throttle openings (6) or a non-return valve (7). By virtue of the bellows (9), which forms a flexible outer envelope, the shock absorber does not require sliding seals to seal it off from the outside. The hydraulic fluid (13) fills the bellows (9) partially and above the fluid level (14) is air, which communicates with the outside air via a connecting passage (15). This hydraulic buffer thus operates virtually unpressurised in relation to the interior (5) of the bellows (9). The shock absorber shown is here designed as end-position buffers, a return spring (17) serving for repositioning to the initial position.   The shock absorber according to the invention can also be designed as a double-acting shock absorber or, for example, be integrated into a pneumatic spring system, in which latter case the flexible outer envelope is airtight. <IMAGE>

Title: Method and device for controlling a kneading and mixing machine
IPC: A21C1/14
Filed: 1987-12-29
Abstract: The invention relates to a method for controlling a kneading and mixing machine, if desired with the outlet devices, which are assigned to it, of the silos containing the ingredients, especially for types of flour and water, for the automated production of dough for bread or pastry articles following different recipes. The kneading and mixing machine is, to permit programming of its various speed ranges, connected to a time switch system and has sensors for measuring values indicating the state of the dough. Into the time switch system which takes the form of a programmable computer with an input keyboard there is input an identification key to call up a stored recipe and the program for following it, as a result of which the selected program is used to indicate the quantities and necessary state variables of the necessary ingredients or the said ingredients are called for by actuation of appropriate circuits of the outlet devices of the silos in question and are fed in prescribed quantities to the kneading vat with software being provided to take account of their continuously measured initial status values which are fed to the computer. During the entire mixing and kneading process, temperature values which are recorded in the vat by at least one sensor are continuously fed to the computer which evaluates them to obtain the desired values for the state of the dough in the kneading phase which are predetermined by the software and emits control commands for adaptation of the mixing and kneading process to the kneading machine.

Patent DE-3806059-A1 (DE)
Title: Cutter for mincing machines
Inventor: HAACK EBERHARD DR ING
IPC: B02C18/36
Filed: 1988-02-26
Abstract: The invention relates to a cutter for mincing machines which can be used in single and multi-part cutting sets and is used in all sizes of mincing machine. The cutter according to the invention is designed in such a manner that it has an outer ring, slides in guides and is arranged in the outer ring so as to rotate and so as to be replaceable. The guides comprise an annular groove provided at the periphery of the cutter and a bead running around in the inner diameter of the outer ring. An essential feature is to be seen in that the two parts, the cutter and its outer ring, have the same width and thus a zero dimension with respect to each other. By this means, it is possible for a frictionally engaged and positive-locking connection between the cutter and the respective perforated plate to be provided when the cutter is used in the cutting set of a mincing machine, which ensures that good quality cutting or disintegration of the material being processed is achieved with low friction and a low energy requirement.

Title: Spiral chute for bulk-material bins
Inventor: SCHNEIDER HERIBERT DIPL ING
IPC: B65G11/16
Filed: 1988-03-17
Abstract: Spiral chutes, in particular outer spirals on bins, for downward conveying of bulk materials, such as hard coal, have, as seen in section, a chute throat and a vertical projection and an inclined or convexly curved region directed towards the eye of the spiral. In particular the chute throat is lined with tiles consisting of a highly wear-resistant material. For the purpose of economical saving of very expensive wear material while, at the same time, avoiding the destruction of adjacent tiles, the tiles are constructed as combination tiles (1) which can be laid in a mortar bed, ceramic elements (3, 5) consisting, for example, of oxide ceramic material being provided at least partially on a base plate (2) formed from high-quality concrete, and being adhesively bonded to the latter in a toothed arrangement (Figure 1). <IMAGE>

Title: Perylene dyes of high dielectric constant - use of the dyes as a dielectric
Inventor: LANGHALS HEINZ PROF DR
IPC: H01G4/18
Filed: 1988-04-29
Abstract: A description is given of perylene dyes, perylene-3,4 : 9,10-tetracarboxylic acid bisimides, having dielectric constants of up to 110. By building up polymeric structures, values of up to 190 are achieved. These high values are maintained even at high frequencies extending into the infrared range. The insulation resistance (direct-current resistivity) of the dyes is extremely high, so that the substances are particularly suitable as dielectrics for high frequencies also. It is possible to produce thin layers of dye, for example by vapour deposition or compression techniques, so that it is possible to obtain capacitors of large capacity (capacitance). The dyes have a degree of thermal, chemical, photochemical and radiation-chemical stability which is unusually high for organic materials, so that they can also be employed under unfavourable operating conditions.

Title: Ultrasonic transducer
Inventor: DOERR HELMUT
IPC: G10K11/00
Filed: 1988-08-06
Abstract: An ultrasonic transducer, particularly for distance warning systems in motor vehicles, is described in which the pot-shaped resonant element is held on a prefabricated plug of a silicone rubber which is pressed into a receiving chamber of a carrier. This plug acts as holding element and, at the same time, as damping element for the resonant element with the piezoelectric disc applied to a diaphragm. In addition, the feed line is bonded to the piezoelectric disc by means of a conductive adhesive, which is easier to implement in production terms than the usual soldering.
Patent DE-3829722-A1 (DE)
Title: Circuit for generating alternating voltages with an improved conversion efficiency
Inventor: GEHM HELMUT DIPL PHYS
IPC: H03F3/217
Filed: 1988-09-01
Abstract: A circuit arrangement for increasing the conversion efficiency of externally controlled oscillators is proposed which is advantageous in class C amplifiers, direct-voltage converters and electrical ignition systems. The circuit arrangement has the effect that when the Qs of the resonators are sufficiently high, the internal losses of a bipolar transistor are minimised during the inverse phase and that no beta degradation of its current gain occurs. Furthermore, the circuit arrangement provides for a wider range for frequency and/or load variation with only little reduction in the conversion efficiency.

Title: Differential phase-shift arrangement
Inventor: SOLBACH KLAUS DR
IPC: H01P1/18
Filed: 1989-01-28
Abstract: A phase-shift arrangement for producing a wide-band defined transmission-phase difference between two waveguide paths has different conduction lengths for the two waveguide paths and cut-off frequencies varying over a waveguide section. The resulting curve of phase difference against frequency exhibits a particularly flat part, in the region of which the phase difference scarcely changes over a wide frequency band. Because of the flat design, the phase-shift arrangement is particularly advantageously usable in conjunction with a 3dB-90@ coupler as monopulse comparator instead of the usual double-T junctions.
