Patent DE-3142715-A1 (DE)
Title: Adjustable radial piston pump
Inventor: EHEIM FRANZ
IPC: F02M41/14
Filed: 1981-10-28
Abstract: The adjustable radial piston pump according to the embodiment in Fig.1 has a rotor with a plurality of pistons, the outer ends of which slide on a cam ring (24), which can be twisted by a hydraulically operated sliding piston (31) for the purpose of adjusting to the no-stroke position. Control ducts (52, 66) for the feeding and removal of the pressure medium fed by an auxiliary pump (40) on the low pressure side are formed in a distributor (38) integrally formed with the rotor. Due to twisting of the cam ring (24) the low pressure control is so adjusted that the delivered pressure medium can flow directly back to the low pressure side. In the delivery position of the cam ring the pressure medium is led by way of a pressure valve (48) to the consumer side, for example to injection nozzles of an injection pump. Adjustment of the cam ring may be advantageously performed by way of a servo piston control, which is actuated by way of a preferably timed solenoid valve (61). The pump may also advantageously be equipped with an intake throttle control (100). <IMAGE>

Title: Synchrotron X-ray radiation source
Inventor: TRINKS UWE HANNO DR
IPC: H05H13/04
Filed: 1981-12-04
Abstract: The synchrotron X-ray radiation source, which is described as a preferred exemplary embodiment of the invention, contains an electron storage ring with a system of superconducting coils and magnets, and a nominal circle radius of 287 mm, also an injector arrangement consisting of a linear accelerator, which is connected directly to the storage ring and allows said storage ring to be filled by a single 8 MeV electron pulse. The storage ring operates with weak focusing and, apart from storage of electrons, is also used to accelerate them from the injection energy to the final energy of 430 MeV. As a result of this design, the apparatus cost can be kept relatively small so that the X-ray radiation source is not restricted to use in large research installations but can also be used for example in industry for X-ray lithography.

Title: Coupling device
Inventor: LUNGU CORNELIU DIPL ING
IPC: F16H63/00
Filed: 1982-11-24
Abstract: The coupling device (2), which is part, in particular, of a two-speed transmission (3), has a hollow shaft (4), a permanently magnetic armature (15, 16, 17, 18) displaceable in the said shaft, polarised in its longitudinal direction and having wedges (13, 14) arranged at both ends, a magnet coil (19) arranged around the hollow shaft (4), fixed soft-magnetic bodies (21, 22) in the form of annular discs on both sides of the magnet coil (19) and, next to the said bodies on the hollow shaft (4), rotatable coupling sleeves (5, 6) with coupling grooves (7, 8) facing towards the hollow shaft, and coupling balls (11, 12) which are situated in openings (9, 10) in the hollow shaft and are aligned radially to the coupling grooves. In response to a current pulse within the magnet coil (19), the armature (15) displaces the wedge (13) towards one coupling sleeve (5) and hence also displaces the coupling balls (11) radially outwards, bringing about torque transmission between the hollow shaft (4) and the coupling sleeve (5). The soft-magnetic bodies (21, 22) hold the armature (15) and the wedges (13, 14) in the said coupling alignment. A current pulse of the opposite polarity effects a displacement of the armature (15) into the other position, the coupling procedure thereby being reversed. <IMAGE>

Title: Signalling detector for telephone PBX systems with direct dialling-in
Inventor: SIEGMUND GERD ING GRAD
IPC: H04M7/00
Filed: 1983-02-26
Abstract: Telephone PBX systems with direct dialling-in contain direct dialling-in exchange line interfaces which are connected via the two-wire exchange line to a direct dialling-in interface in the associated exchange. The switching tasks of the line selector in the exchange are transferred to the PBX system. In order to avoid the multiplicity of different circuits hitherto required to identify the outgoing and incoming signalling characters in the PBX system, the signalling detector has an analog-digital converter ADW connected to the a-wire and the b-wire of the exchange line AL, and a digital evaluation circuit AWS which evaluates the output signals of the above-mentioned converter and which in turn transmits the signals controlling the direct dialling-in exchange line interface. <IMAGE>

Patent DE-3314568-A1 (DE)
Title: Sunscreen composition
Inventor: KUEHNE JOSEF
IPC: A61K8/92
Filed: 1983-04-22
Abstract: A sunscreen composition which is based on petroleum jelly, contains as aqueous emulsion a mixture of aromatic additives, absorbs at a particular mixing ratio the short-wavelength UV rays which produce erythema, and ensures over a lengthy period an adequate supply of moisture to the skin. At the same time, the sensitivity of the skin to erythema is reduced, and pigmentation is promoted; the active ingredients in the sunscreen composition care for the skin and cure the skin irritation caused by abrasions (rubbing with towel or the like, contact with grains of sand etc.) and heal other minor injuries. The long-term action of the sunscreen composition according to the invention makes it unnecessary, even on prolonged exposure to the sun, to carry out frequently repeated applications of protective layers which otherwise slow down pigmentation, because they let through less light with each new layer.

Patent DE-3338289-A1 (DE)
Title: Spring pressure-actuated and electromagnetically releasable friction brake
Inventor: MAWICK HANS-OTTO ING GRAD
IPC: F16D55/00
Filed: 1983-10-21
Abstract: A description is given of a spring pressure-actuated, electromagnetically releasable friction brake which comprises an annular electromagnet body and an annular armature part which can be displaced axially relative to the latter and is pressed axially against the friction body adjoining it and against a brake flange by spring pressure and, upon excitation of the electromagnet body, is displaced counter to the action of the spring. The armature part here comprises a plurality of mutually independent solid armature discs of magnetic material arranged one behind the other in the axial direction, of which preferably at least two differ in their axially measured thickness, the armature disc adjoining the magnet body always being one of those of lesser thickness. This configuration results in a considerably lower impact noise upon release, especially, however, also when the brake comes into contact, than is the case in the prior art. Also advantageous is the fact that manufacture is simple. A favourable effect on noise damping is likewise achieved by the subdivision of the mass of the individual armature discs.
