Patent DE-4022500-A1 (DE)
Inventor: LECHNER GISBERT PROF DR ING
IPC: F04C2/08
Filed: 1990-07-14
Abstract: A gear machine, pump or motor, has two rotatively guided toothed wheels (1, 2) in a housing, the toothings of which are mutually engaged and separate a compression chamber (5) from a suction or discharge chamber (4). Depending on the rotation angle  phi 1 of a torque-transmitting toothed wheel (1), an instantaneous hydraulic medium volume flow V is displaced and the mutually engaging toothed wheels (1, 2) have a multiplication ratio i =  phi 1/ phi 2. In order to avoid pressure fluctuations and the resulting sound projection, the instantaneous multiplication ratio i over the whole angle of rotation  phi 1 of the torque-transmitting toothed wheel (1) is selected in such a way that the non torque-transmitting toothed wheel (2) is driven at a constantly changing, periodically returning angular speed by tooth pitch, thus totally or partially compensating by an output increase or reduction the volume flow pulsation caused by the constant change in the position of the sealing limit at the teeth contact point.

Title: Recycling of used X=ray film - by cutting up film subjecting to enzyme based hydrolysis to separate gelatin and recovering silver@ by high temp. treatment
Inventor: POSPISIL ZDENEK ING
IPC: G03C11/24
Filed: 1991-04-06
Abstract: In recovery of used X-ray film, the film material is first cut into small pieces which are then subjected to enzyme based hydrolysis to separate the gelatine layer and silver is recovered from the residue. The contents of the hydrolysis baths and washing water is circulated to a vacuum evaporator for drying and the distillate recirculated. Remaining solids are subjected to a high temp. pre-treatment to recover the metal. 1000 Kg of used film are cut into small pieces approx. 8 x 8 mm in a granulator. Smaller pieces of material were removed by sieving. The granulated film is fed into a washing drum, rotating in a water bath at 40-48 deg.C, where an enzyme based hydrolsis occurs. Hydrolysis lasts 25-30 mins., after which the sieve drum is cleaned several times with water at 70 deg.C. The water to solids ratio is 2:1. After washing solids are dried in a special drying drum and recovered plastics material can be reused.

Title: Rotary vibration damper for IC engine - has viscous damping medium and flywheel has magnetic ring tracks for accurate centring
Inventor: BUETTNER SIEGFRIED DIPL ING
IPC: F16F15/173
Filed: 1991-06-03
Abstract: The damper has a flywheel mass floating in a closed chamber of an annular housing. One or more magnetic ring tracks (6, 7) are provided as an active connection in the housing (1) and in the flywheel mass (4) radially opposite relative to the axis of rotation (12). The facing surfaces of the ring tracks deviate in the axial direction (8, 9; 10, 11) from the direction of the axis of rotation. Where there are two active connections, each with two magnetic ring tracks, the faces in the axial direction run parallel to each other. The direction of the faces in the axial direction of one connection deviates by a positive angle. The direction of the faces in the axial direction of the other connection deviates by a negative angle. USE - By altering the angular position or curvature of the faces in the axial direction it is possible to control the size ratio of the radial to axial force components so that the centring of the flywheel mass in the housing is improved.

Title: Hydrostatic drive with open circuit arrangement of motor - has vacuum relief valve to prevent cavitation during braking by allowing oil flow from motor outlet to inlet
Inventor: DEININGER HORST DIPL ING
IPC: F16H61/40
Filed: 1991-06-12
Abstract: The hydrostatic drive has a pump (1) supplying a motor (6) which is rotatable in both directions and is arranged in open circuit. In hte circuit is a vacuum relief valve (16) which is controlled by the inlet and outlet oil pressure of the motor and, when open, connects the inlet and outlet lines (4, 5) so that oil can flow from motor outlet to motor inlet, thus preventing cavitation when the motor operating in a braking mode. Since the motor can rotate in both directions, the system has in-parallel arrangements of throttles (7, 10) and relief valves (13, 15) on each side of the motor. The positions of the relief valves are used to hydraulically signal the actual inlet and outlet sides of the motor.

Title: Medicament from camomile flowers - contains non-polar active agent obtd. by aq. extn. in presence of ascorbic acid
Inventor: KONRAD KARL
IPC: B01D11/02
Filed: 1991-09-20
Abstract: A medicament (A) contg. non-polar active agents from the petals of camomile flowers is claimed. More specifically, (A) can also contain polar active agents from camomile flowers. The petals are sepd. from the remaining parts of the flower, mixed with an aq. soln. of ascorbic acid or an ascorbate and percolated to give an extract contg. non-polar agents. The percolation is pref. carried out in the presence of a solvent which is lighter than water, e.g. paraffin, and then additional solvent is forced through the extract in a countercurrent procedure in order to remove polar components present. Subsequently, the residue from the percolation is mixed with the previously unused parts of the flower and the mixt. is percolated to give an extract contg. remaining polar agents. This percolation is pref. carried out using ammonia/water/ethanol. USE/ADVANTAGE - (A) is used as an antiinflammmatory, antispasmodic and to treat flatulence. (A) makes optimal use of the therapeutic substances present in camomile flowers, unlike previously used infusions and extrats in which the non-polar flavenoid components are lost during preparation

Title: Internally coated concrete storage and treatment vats - in which the surface of the concrete is roughened by spraying with water under pressure soon after commencement of hardening prior to coating
Inventor: WEILER WALTER DIPL ING
IPC: B24C1/06
Filed: 1992-02-06
Abstract: Process involves applying coating to the inner surfaces after sufficient hardening of the concrete. But before applying the coating and shortly after the commencement of the hardening the surfaces to be coated are roughened by spraying with water under pressure. USE/ADVANTAGE - The water spray is easier to apply than the sand blasting used previously, and the water rinses off loose surface deposits from the concrete and roughens the surface so that it is fully conditioned to receive the coating. The spraying procedure can be automated and applied, e.g., after demoulding the vats during the prodn. process. The water spray can be combined with application of impregnating agents, e.g., water soluble epoxy resin. After spraying, the vats are allowed to dry and are then ready to receive coating to render them resistant to waters contg. harmful or aggressive media, esp. multilayer coatings of the type covered by DIN 4281.
