Title: Hydraulic circuit for a mounted half-turn plough
Inventor: BRANDENBURGER WALTER DIPL ING
IPC: A01B3/421
Filed: 1989-03-18
Abstract: The invention relates to a circuit for a mounted half-turn plough equipped with a plough-turning device which reverses automatically in a pressure-dependent manner and with a swivel mechanism arranged parallel thereto. Swivel mechanisms are used to bring the centre of gravity, which lies far to the outside in multi-share ploughs, closer to the turning axis, and in addition to reduce the size of the turning radius, so that the plough does not cut into the soil when turning. Known circuits permit a simultaneous movement of the turning and swivel cylinder, as a result of which time can be saved under optimal conditions. However, under unfavourable conditions, such as, for example, steep inclines, the speed of turning may then not be sufficient to go beyond the dead centre of the movement, as a result of which the turning procedure must be interrupted. This disadvantage is aggravated, on the one hand, even under normal conditions, if only a comparatively small delivery quantity is available from the tractor and if a proportion of this small delivery quantity is removed. On the other hand, in the case of falling ploughs, the plough may cut into the soil even before adequate swivelling-in has taken place. In this respect the invention provides for greater functional reliability by using two priority valves in the connections of corresponding working chambers, as a result of which in each case it is possible to block the discharge from the working chamber of that cylinder whose movement to the respective ...

Inventor: JOECKEL ULRICH DIPL ING
IPC: F16L55/165
Filed: 1989-07-07
Abstract: A process for the renovation of sewer pipes using an inner pipe which is impregnated with a curable resin proposes that the inner pipe is inserted into the relevant channel section in the axial direction and is moved into an opposing position with respect to the damaged pipe section. The inner pipe (wrapped with a displaceable overlapping region) is initially inserted into the channel with a diameter reduced in comparison with the internal diameter of the channel and is moved into a position opposite the damaged pipe section. A bladder, which is expandable in the radial direction and folds the inner pipe outwards in the radial direction when excess pressure is applied, is arranged in the inner pipe. Devices for curing the resin are arranged in the bladder.

Title: Spread spectrum communication system - uses convolver as correlator for pseudo-random code signals
Inventor: HAMATSU MASAHIRO
IPC: H04B1/707
Filed: 1990-02-07
Abstract: A spread spectrum communication, SSC, transmitter has a pseudo-random code generator (24) operated with a clock generator (23) that supplies a mixing stage (26) with an input from an oscillator (25).

Title: Mixing chamber - for atomisation of two flowable media
Inventor: LEINBERGER KLAUS
IPC: B01F5/00
Filed: 1990-03-17
Abstract: When two media are finely mixed by atomisation in a chamber where one medium moves slowly and is impinged at high speed by another, the chamber only works efficiently at one optimum throughout. The novelty is that the inlet orifices for the first medium are covered by spring plates which also form a slot between the plate and the mixing chamber face, and form a slot-shaped egress. The first medium is introduced through one slot (3) and the second medium through another (4). The spring plate (7) covers the inlet (4). The atomised media leave through a slot (6) to produce a jet. USE/ADVANTAGE - The unit forms a turblence nozzle to atomise oxygen and oil for combustion or to mfr.  metal powder by atomising liq. metal with liq. inert gas.  The slot width and thus the throughput can be determined by the pressure of the medium as it flows through, or by an adjustor screw, with no loss in efficiency.

Filed: 1990-06-19
Abstract: A continuous and/or controlled release form of flutamide is obtained by mixing flutamide and conventional pharmaceutical excipients with a retarding element constituted by an anionic copolymer of methacrylic acid and methyl methacrylate, alone or in combination with other retarding elements. A test to measure release of flutamide and a method to determine the bioavailability of it comprises extraction of the flutamlde with methanol and high pressure liquid chromatography on the resulting solution. The pharmaceutical forms obtained in this way, specifically the tablets, have a longer residence time in the bloodstream, have greater bioavailability and allow decreasing of the dose. They are useful in the treatment of prostate hyperplasia and advanced prostate carcinoma.

Patent DE-4028315-A1 (DE)
Inventor: MOECKL THOMAS DIPL PHYS
IPC: B06B1/06
Filed: 1990-09-06
Abstract: The ultrasonic transducer comprises a piezoelectric radial oscillator (16), preferably of a piezoceramic, fitted with electrodes (18, 20) on both sides. To one side are applied a first and second matching layer (26, 32) the thickness (dA, dB) of which is smaller than a quarter of a natural wavelength ( lambda ) of the transducer. Thus no resonance matching is performed here. On the other side of the radial oscillator (16) is secured a damper (36). a needle-pulse voltage (U(t)) is applied to the electrodes (18, 20) by capacitor discharge. The composite action of the radial oscillator (16) and the two matching layers (26, 32) then results in thickness oscillation owing to radial-thickness coupling. The aforementioned natural wavelength ( lambda ) of the transducer is then the one which is produced as a result of natural resonance during thickness oscillation. The first three half-waves (1, 2, 3) of the ultrasonic pulse (I(t)) released on excitation at the most are evaluated.
