Patent DE-3837038-A1 (DE)
Title: Misalignment-compensating coupling
IPC: F16D3/38
Filed: 1988-10-31
Abstract: Such couplings generally serve to compensate for angular misalignments between an input and an output shaft or to take up changes in length. In order to compensate both for an angular and an axis-parallel misalignment between the input and the output shaft, an input flange disc is connected to an outer ring (6) from which two diametrically opposite first pins (5) project inwards and are seated in first sliding bearings (3) of a swinging wobble ring (1). Two further pins (4), diametrically opposite one another, project outwards from the output flange (7) and are seated in second sliding bearings (2) of the swinging wobble ring (1). The axes of the first pins (5) and first sliding bearings (3) are perpendicular to the axes in the second pins (4) and sliding bearings (2) and lie in common plane with them. The misalignment-compensating coupling has a small overall length and permits rotationally rigid, play-free transmission of torques between rotating bodies, which can have both angular and axis-parallel misalignment relative to one another. <IMAGE>

Title: Circuit arrangement for the variable supply of an ohmic load from an AC network
Inventor: ALBACH MANFRED DR
IPC: H02M3/156
Filed: 1988-11-12
Abstract: The invention relates to a circuit arrangement for the variable supply of an ohmic load from an AC network having at least one switched-mode power supply. It is known to drive a semiconductor switch of a switched-mode power supply in such a way that a sinusoidal network current is created and the load current or a coil current, respectively, flows continuously or has gaps, the immediately beginning gapping operation exhibiting a best compromise with respect to losses etc. Depending on the switch-on duration, the corresponding switch-off duration is then, however, to be determined. For this purpose, the load current must be detected, and when it becomes zero, a pulse must be generated for the semiconductor switch to be switched back on, which involves considerable difficulties, for which reason the times of switching on and off of currents and voltages in the switched-mode power supply are controlled for the entire output power range to be set, such that, with inclusion of the power-dependent impedance of the load, a triangular current is produced, whereby a sinusoidal network current is guaranteed, low losses and reduced high-frequency interference levels are achieved and, above a specific output power, the load can be connected directly onto the AC voltage network.

Title: Apparatus for waste water purification by floculation and flotation
Inventor: MUELLER HEINZ JOACHIM
IPC: C02F1/52
Filed: 1989-01-12
Abstract: In waste water purification by floculation and flotation, the floculation operation is carried out in tanks which are connected upstream of the flotation, or in non-optimised pipe sections within flotation plants. By means of the specific mixing of the gas bubbles necessary for the phase separation in flotation with the dirty water prior to floculation and introducing the energy required for the floculation by an arrangement of perforated discs, the combination of floculation and flotation is achieved in compact waste water (effluent) purification plants under technologically optmised floculation conditions.
Patent DE-3902739-A1 (DE)
Title: Radar antenna array
Inventor: LIEM GWAN DIPL ING
IPC: H01Q3/36
Filed: 1989-01-31
Abstract: For a radar antenna array having a supply line which is connected via a T/R cell to a transmitter and a receiver and, during transmission, distributes the transmission signal to double radiating-element rows and, via 3dB couplers, to the radiating elements of the two individual rows of each Doppler row which are polarised orthogonally with respect to one another, an additional receiving line is provided, which is likewise connected to the 3dB couplers. The antenna can be operated via controllable phase shifters both with two independent polar diagrams of orthogonal polarisation and with a single polar diagram of selectable polarisation. The received signals which are obtained via the supply line and the receiving line can advantageously have superimposed on them an adjustable amplitude weighting and phase shift so that, for example, the received polarisation can be set independently of the transmitted polarisation. By adding an additional distribution device to the supply line and/or to the receiving line to form a conductor network, the antenna can be extended for monopulse operation.

Filed: 1989-06-19
Abstract: 2.1 In the actuation of a roller shutter, more or less substantial generation of noise inevitably takes place, in particular in the case of metal roller shutter slats. The new roller shutter slat is intended to reduce this generation of noise. The new method is intended to permit simple and economic manufacture of such roller shutter slats. 2.2 According to the invention, the walls of a metal roller shutter slat are provided with coatings of different layer weights. The correspondingly asymmetrical distribution of weight on the walls results in damping of the vibrations of the entire system, and hence in a significant reduction of the generation of noise. According to the proposed method for manufacturing such a roller shutter slat, an aluminium strip is initially provided with a plurality of adjacent longitudinal layers of different layer weights. The coated strip is divided into longitudinal slivers with at least two adjoining layers. The slivers obtained are converted to the roller shutter slats according to the invention by conventional roll forming. 2.3 Sound-adsorbent roller shutter slats and their manufacture. <IMAGE>
