Patent DE-3316775-A1 (DE)
Title: Interconnected control of photocells for adaptation to electrical loads or accumulators
Inventor: MAHR HANS DIPL ING
IPC: H02J7/35
Filed: 1983-05-07
Abstract: A method for adapting photovoltaic solar cells to electrical loads, using simple electromechanical and/or electronic switching members. The principle is based on the fact that a single sensor photocell measuring the respective light intensity is interrogated by a programmed computer which, in turn, then connects the actual large number of operating photocells in each case, by means of a system of relay elements, group by group in series and/or in parallel so that the power is optimally adapted to the electrical load or storage accumulator. The method according to the invention saves the high electrical losses and expensive installation involved in fully electronic adaptation, in which the photovoltaic direct current is switched from solar generator to load by chopping, transforming and re-rectifying.

Patent DE-3323344-A1 (DE)
Title: Indirect measurement data acquisition and integrated measurement and control method for suspended magnets
Inventor: WEH HERBERT PROF DR ING
IPC: G01B7/14
Filed: 1983-06-29
Abstract: A reliable and simple acquisition of the mechanical variables required to stabilise the suspension process, such as gap, 1st and 2nd time derivative of the gap, as well as the vertical acceleration of the support magnets is described. Use is made for this purpose of uniform electrical and magnetic measured variables which are measured (in analog fashion) on the support magnet itself and on an additional magnet sensor between the support magnet and suspension frame. The 4 required mechanical variables which define the suspension status can be determined therefrom by calculation in an electronic computer (microcomputer). Instruments such as inductively operating gap sensors or accelerometers, which are based on the moving-coil principle, are thereby rendered dispensable. The digital output variables of the microcomputer can be fed as input variables, without analog conversion, directly to a computer simulating the controller, which once again is a microcomputer. These computer output signals serve for (pulse-width) control of the amplifier output stage (e.g. DC voltage controller for influencing the current of the support magnet). A uniform and in principle simple measurement and control method for electromagnets or magnets excited in a mixed fashion electrically and by permanent magnets is thereby achieved. The method provides the possibility of including further variables in the control, and permits an adaptive configuration of the controller concept from various points of view. By contrast with previous methods,... Original abstract incomplete.

Patent DE-3337655-A1 (DE)
Title: Process and apparatus for purifying water polluted by hydrocarbons
IPC: B01D17/02
Filed: 1983-10-17
Abstract: Water (3, 19) contaminated by hydrocarbons is passed through an adsorption/coalescence composition (8) and here undergoes adsorptive purification until the saturation limit is reached. The purification action, because of the adsorptively saturated composition (8) and its arrangement in a perforated casing (9), is then carried out by the coalescence principle (10), that is aggregation of the oil droplets distributed in the water to form oil drops having a diameter corresponding to the perforations of the casing (9). The water stream (3, 19) contaminated by hydrocarbons undergoes, via the coalescence action of the compositions (8) used and the chamber arrangements (7, 8, 11, 12, 17), a fractionation into a clean water stream (21) and an oil drop stream (20) and an oil layer (22). <IMAGE>

Patent DE-3339679-A1 (DE)
Title: Evacuation device for rotary pumps
Inventor: HANSELMANN GERHARD DIPL ING
IPC: F04D9/04
Filed: 1983-11-02
Abstract: An evacuation device for rotary pumps, in particular fire- extinguishing rotary pumps, is described in which in the initial operating phase, i.e. until the rotary pump operates in a self-priming state, the suction chamber is evacuated by means of a positive displacement pump, preferably a liquid-seal pump. In order to prevent fire-fighting water entrained by the evacuation gas flow reaching the liquid-seal pump and diluting its working medium (a concentrated antifreeze), there is provided, in the flow path leading from the suction chamber of the rotary pump to the suction side of the liquid-seal pump, a liquid separator which retains the transport medium. A further separator which is connected to the outlet of the liquid-seal pump has the effect that the working medium of the pump is retained and can collect again in the pump reservoir. The inflow to the working medium separator and the emptying thereof as required are controlled with the aid of two 2/2-way magnetic valves which, by means of the output signal of a pressure switch responding to the output pressure of the rotary pump, are controlled to take up alternately their stop position and their throughflow position. The pump system is largely maintenance-free.

Title: Screw conveyor which can be conditioned by air for migrating-bed granular-bed filters for treating the contacting medium
Inventor: NEUMANN GERHARD MAX
IPC: B01D46/34
Filed: 1983-11-01
Abstract: A screw conveyor, which can be conditioned by air, based on brushes for migrating bed filters or packed-bed adsorbers, in addition to and during its function as feed or discharge apparatus, at the same time takes over the moistening, wetting, drying, heating or cooling of the contacting medium. Even acting as a distiller in some cases, a condenser to be connected to the conveyor barrel can be dispensed with. If required, the bush screw conveyor apparatus operates together with a plurality of material separation stages, in order to split the individual gas phases. The drive of the screw conveyor apparatus is simultaneously the drive of a smoothing apparatus for the adsorbent surface during packing. A hot air expulsion stage with subsequent condensation can be intermediately connected at the inclined tube connection section of the bush screw conveyor, while cooling and drying is carried out in the barrel of the screw conveyor during transport. The exhaust air from the screw conveyor, if required, is returned to the feed connection piece of the adsorber. This system can be used for all granular materials for filtering or drying or for other similar applications in conditioning. The avoidance of appearance of abrasion of amorphous or soft abrasion-sensitive granular adsorbents during transport is, moreover a further advantage compared with migrating-bed adsorbers or driers of the prior art.
Patent DE-3340153-A1 (DE)
Title: Vibration-free attachment device
Inventor: OHTA YOSHIO
IPC: F16M7/00
Filed: 1983-11-07
Abstract: The attachment device comprises a first and a second main part which in each case can be permanently fitted to one of two objects which are to be connected to one another. An annular element, produced from elastic material, is connected to the first and second main parts so that these parts bound a pressure chamber which is connected to the outside via a first and second opening, which are constructed in the second main part. In the event of a relative movement of the two main parts with respect to one another, the size of the pressure chamber changes, with deformation of the elastic element. A first shut-off element controls the flow resistance of the first opening between a first relatively low value, when the amplitude of the relative oscillation movement between the first and second main parts is relatively small, and a second relatively high value, when the amplitude of the relative oscillation movement between the two main parts is relatively large. A second shut-off element, which can be controlled from the outside, opens or closes the second opening in a selected manner.

Title: Suction belt conveyor
Inventor: MUENCH WALTER
IPC: B65H29/24
Filed: 1983-12-03
Abstract: In a suction belt conveyor, the plate (1), onto whose underside the lower runs of the continuously circulating belt (3) abut and which is provided with suction apertures (9), is provided with longitudinal grooves (2). One suction aperture (9) opens into each groove (2), at least at the delivery end. A longer section which is free of suction apertures is connected to this in the direction of transport. Transverse grooves, which are likewise connected to suction apertures, may also be present. Besides requiring less suction, the invention is especially advantageous in that it facilitates ejection of the conveyed material. It is furthermore advantageous specifically for sheets of veneering material and similar easily deformable sheet-like material in that such material is automatically smoothed out. <IMAGE>

Title: Frequency divider
Inventor: BLIND MANFRED ING GRAD
IPC: H05K1/02
Filed: 1984-04-07
Abstract: In a frequency divider for the VHF range, in each case with at least one band-pass filter comprising balanced, inductively base-coupled resonant circuits and a band-rejection filter comprising a series resonant circuit between its input and earth and a parallel resonant circuit between its input and output, the series element of the band-rejection filter is formed from the parallel connection of a fixed capacitor and at least two air coils disposed in pairs symmetrically in relation to it and wound in opposite directions; the resonant circuits of the band-pass filter are series resonant circuits with fixed capacitors and coils disposed roughly in parallel with one another and wound in opposite directions whose end parts which are connected to earth are designed as straight conductor pieces lying roughly in parallel opposite one another and running parallel to the coil axes. This frequency divider is designed simply and economically compared with the state of the art, can be adjusted quickly and in stable fashion, and, due to a high return loss on all terminals over a wide frequency range, is suitable for cascading.
