Patent DE-3106679-A1 (DE)
Title: Device for re-concentrating and collecting sunlight, which has been focused by a water lens roof
Inventor: KEMMLER KARL
IPC: F24S23/30
Filed: 1981-02-23
Abstract: The invention describes how the strips of maximum focusing of the light generated by the adjacent areas of a water lens roof are collected via vertically and horizontally displaceable traverses. The latter are designed as rotatable parabolic grooves for further concentration of the light. The vertical and horizontal movements are made possible by drive weights AGV and AGH, respectively. Once the AGV have been raised by means of the rope winches SWV, they then drop downwards and pull the traverses upwards, as soon as current flows through the magnetic brakes MBV. If the AGV are standing on the consoles, then the traverses can drop downwards, with unwinding of the rope winches. The displacement of the traverses relative to the transverse direction of the roof takes place in a very similar manner. Figures 1 and 2 show the associated mechanics. In addition, the invention describes and discusses in greater detail, with reference to Figures 3 to 7, how the movements of the traverses can be controlled by the sunlight. <IMAGE>

Title: Centreboard with centreboard case for sailing boats, in particular sailboards
Inventor: SCOPINICH VITTORIO
IPC: B63B41/00
Filed: 1981-03-11
Abstract: The invention relates to a centreboard with centreboard case for sailing boats, in particular sailboards, in which the centreboard can be inserted into the centreboard case and is mounted in a hinged manner in the centreboard case. The centreboard is supported in a spring-mounted manner with its two side faces on the centreboard-case walls opposite the side faces and, with its shaft projecting downwards out of the base of the centreboard case, can be pivoted against the spring force laterally towards the centreboard-case walls by side forces acting on the shaft in the sailing state of the boat or board. In addition, the centreboard can be pivoted about an axis of rotation, arranged transversely to the longitudinal axis of the centreboard case above a line separating the centreboard head from the centreboard shaft near the front marginal edge of the centreboard head, against the action of an elastic tension device from the swung-in position into the swung-out position. The wetted surface of the centreboard and thus the lateral plan are thereby reduced in the sailing state of the boat or board. In addition, shock absorption is achieved by the elastic laterally acting springs of the centreboard and an additional buoyancy effect of the centreboard automatically tilting laterally. The shock absorption permits the use of a rigid sail mast and thus results in less deformation of the sail profile so that the planing capacity of the board or boat is increased without reducing the sailing safety.

Title: File for perforated documents or similar sheet-like inserts
Inventor: SCHUDY KARL-HEINZ
IPC: B42F13/12
Filed: 1981-08-22
Abstract: A file for perforated documents or similar sheet-like inserts consists of two binding parts and a number of book screws which extend through the gap between said binding parts, engage in perforation channels formed by the perforations of the inserts transversely to their sheet plane, and fix the insert between the binding parts in the form of a sheet pile. In the interests of substantial simplification, the book screws are formed only by cap screws, the outside diameter of whose thread is larger than the diameter of the perforation of the inserts, and the shank length of which is approximately half to equal the size of the spacing between the binding parts, and which cap screws are screwed with their shanks from the mutually opposite binding parts alternately in each case into another one of the perforation channels. In this case, the book screws require conceivably little manufacturing, material and storage expenditure and have an extended field of application with sheet piles of varying thickness between the binding parts of the file.
Patent DE-3135540-A1 (DE)
Title: Isotope separation by the controlled distribution method utilising in particular the isotope concentration effect
Inventor: CABICAR JOSEF PROF DR
IPC: B01D59/36
Filed: 1981-09-08
Abstract: Subject-matter of the present invention forms a method for separating isotopes in two-phase systems of, for example, the solid-liquid, liquid-liquid, solid-gaseous type, which is based on the finding that the distribution of the isotopes can be controlled by the selection of the phase composition, that is by its structural and material nature, by the concentration of the isotopes and ligands, furthermore by the temperature, radiation, hydrodynamic parameters and by the duration of the phase contact. The isotopes of, for example, uranium, lithium and nitrogen can be separated with high efficiency by this method from aqueous and non-aqueous solutions, possibly from gas mixtures thereof, if these are brought into contact with solid sorbents or with liquid extractants. In principle, this is a chemical separation method.

Title: Machine with rotor, especially washing machine with spin cycle
Inventor: DESCHLER GERHARD
IPC: D06F33/48
Filed: 1981-11-17
Abstract: The material spinning in rotors, especially washing machines with horizontal mounting, results, depending on the position, in an unbalance of unforeseeable amount. To achieve a high degree of quiet running by determining the permissible residual unbalance, according to the invention the rotor (1) (see Figure 2) receives on the outer circumference a balancing cross (2) consisting of fillable and emptiable containers (3). The amount and direction of the unbalance are determined by means of a measurement transducer (7) in the bearing of the rotor. A computing unit (microprocessor (8) and control unit (9)) determines the quantity of liquid for the equalisation and filling of the respective containers. If the residual unbalance changes in position and amount and exceeds the permissible value during the spin cycle, the filling of further containers can take place via the regulating device consisting of the measurement transducer (7), microprocessor (8) and control unit (9). After the spin cycle has ended, the centrifugally loaded valves (6) open for the purpose of emptying the equalising containers (3). <IMAGE>

Title: Collapsible child's pushchair
Inventor: MOECKING HERMANN
IPC: B62B7/08
Filed: 1981-12-02
Abstract: A collapsible child's pushchair consists of a collapsible frame which bears a collapsible seat. The said frame is formed from four support rods, which are connected to one another in an articulated fashion and have wheels arranged on the foot-side of said rods, and from two slide rods which are connected to two of the support rods, in which case the support rods and the slide rods can be collapsed into a position in which they are arranged next to one another approximately in parallel. Handling such a collapsible child's pushchair is to be improved so that simply by resting the slide rods on one another it will be possible to collapse the entire frame of the child's pushchair or to unfold it by pulling apart said rods in the collapsed position. For this purpose, the support rods are coupled at the top ends to a central node element which bears the seat and are coupled via expansion rods which are connected to one another in an articulated fashion in a joint node under the node element. At the same time, the slide rods are coupled to the joint nodes of the expansion rods and are guided longitudinally displaceably on the respective support rods.

Title: Electrically operated manual labour device
Inventor: KILLE EWALD
IPC: B25C1/06
Filed: 1981-07-01
Abstract: In an electrically operated manual labour device (1), the electric motor which actuates an axially displaceable impact element (32) is constructed as an AC oscillatory magnet (12) whose armature (15) acts, with a high impact sequence as a function of the mains frequency, on the impact element (32) equipped with a small mass. And said element is inserted, following the frequency of the armature (15), in a cylinder (31) held fixed in a housing (11) of the device (1), with which cylinder an attachment sheath (41) can be detachably coupled, which sheath receives a tappet (43) which is displaceable with respect to said sheath by means of the impact element (32) and acts on a component (2) which is to be driven or on a tool. By means of this design, it is made possible to make a nail driver or the like of extremely compact design since the cylinder (31) which is provided with the impact element (32) can be arranged directly next to the AC oscillatory magnet (12). In addition, the power losses are low since the armature (15) which oscillates about an axis acts directly on the low-mass impact body (32). Furthermore, attachment sheaths which are designed for different applications can be coupled to the cylinder (31). <IMAGE>

Title: Process for the anaerobic purification of waste waters containing furfural, bacteria usable therefor and their isolation
Inventor: BRUNE GERHARD DIPL ING
IPC: C02F3/34
Filed: 1982-03-25
Abstract: The anaerobic treatment or purification of furfural-containing waste water and in particular of the vapour condensates of sulphite waste liquor thickening in cellulose pulp fabrication in the absence of sulphate-reducing and methanogenic bacteria can, according to the invention, be simply started and controlled by addition of furfural-degrading bacteria. Such furfural-degrading bacteria are obtained starting with a source of anaerobic bacteria such as marsh, swamp or in particular sewage sludge with an intermediate enrichment in continuous liquid culture with supply of a furfural-containing solution by means of a special selection technique in which the bacteria (in different concentrations) are fixed in agar which is covered with a dilute solution of furfural, which acts as the sole carbon source and, on diffusing into the agar, forms a concentration gradient within which a concentration range which is tolerated by the bacteria is present in all cases. In this manner, discus-shaped, beige-coloured individual colonies of furfural-degrading bacteria are obtained which are highly motile, are in the form of slightly S-shaped bent rods with flagella and are morphologically similar to Desulphovibrio gigas.

Title: Hydraulic control arrangement for a servomotor
Inventor: KOETTER WOLFGANG DIPL ING
IPC: F15B13/01
Filed: 1982-05-27
Abstract: A hydraulic control arrangement (10) for a servomotor (41) is proposed which has a shut-off valve (36) which can be hydraulically opened in a controlled manner. In this servomotor (10), the control oil flow actuating the release piston (38) is passed during the lowering into the neutral circulation passage (33) to the directional control valve (32) arranged downstream. To this end, a discharge passage (46) connected to the flow port (45) controlled by the release piston (38) leads into a downstream section (28) of the neutral circulation passage (33) in the directional control valve (10) arranged upstream and accommodates a non-return valve (49) which protects the pressure space (35) at the release piston (38). During simultaneous operation of both directional control valves (10, 32) with pressure build-up in the downstream section (28) of the directional control valve (10) arranged upstream, the non-return valve (49) prevents a troublesome pressure build-up in the pressure space (35) so that the shut-off valve (36) safely closes, while at the same time the directional control valve (32) arranged downstream can perform a control function. <IMAGE>
