Patent DE-3402697-A1 (DE)
Inventor: REISCHL ARTUR DR
IPC: C02F3/10
Filed: 1984-01-26
Abstract: The present invention relates to the use of non-floating, non-abrasive, highly-filled polyurethane (urea) compositions of high water-absorbability, which during their production contain no cells capable of growth as carriers for biomasses in the biological treatment of waste-containing liquids. These carriers have a filler content of greater than 15% by weight and less than 95% by weight (based on the moisture-free weight of the filler-containing polyurethanes). The fillers are selected from the group consisting of natural materials containing finely-divided fossil lignocelluloses or the secondary products thereof (e.g., peat, lignite, mineral coal or coke), active carbon, finely-divided distillation residues, inorganic fillers, homogeneous or cellular plastics particles (and more particularly polyurethane foam (waste) particles) and mixtures thereof. The polyurethane (urea) is a hydrophilic and/or hydrophobic polyurethane(urea), and preferably contains cationic groups. These highly-filled, polyurethane (urea) carriers have a water-absorbability exceeding 33% by weight of water in the swollen carrier. These carriers allow improved treatment of industrial and municipal liquid waste to be achieved in biologically-operating treatment plants. Treated waste which has reduced toxicity, a diminished smell, improved clarity and a very small residual content of organic, decomposable material is obtained due to the increased decomposition effect thereof.

Title: Structural elements composed of box-shaped components which are fitted into one another, are mutually encased, or enclose one another so as to be capable of pivoting
Inventor: FOERSTER ARTHUR
IPC: E04B1/343
Filed: 1984-04-02
Abstract: The invention relates to the patent application and auxiliary utility-model application entitled: "structural elements composed of box-shaped components which are fitted into one another, are mutually encased, and enclose one another so as to be capable of pivoting". In the drawings, Figs. Z.1 to Z.7 show the bases of structural elements which can be varied with respect to width or length and width and length, respectively. In the drawings, Figs. Z.8 to Z.11 show that the height of the element can be brought into the position in Figs. Z.8 and Z.9 (saddleback-roof position) or into the position in Figs. Z.10 and Z.11 (flat-roof position) respectively, by pivoting an enclosing component. It can thus be seen from the drawings that the width of the structural elements in Figs. Z.1 and Z.3 is designed in such a manner that they can be used for road traffic and that the dimensions of the element can be altered in-situ. It can also be seen that use can be made of the structural elements in all mutual positions of the components, and that a supporting component is always available into which installation fixtures can be incorporated. <IMAGE>

Patent DE-3420386-A1 (DE)
Title: Fresnel focusing screen for SR cameras
Inventor: JURENZ ROLF
IPC: G02B3/08
Filed: 1984-06-01
Abstract: The invention relates to a Fresnel focusing screen for SR cameras, whose Fresnel structure is situated between the camera lens and viewfinder image plane, by means of which the viewfinder image curvature is removed and an optimum viewfinder image illumination is simultaneously ensured. The Fresnel structure remains invisible to the greatest possible extent in this arrangement. This aim is attained through splitting the refractive power of the focusing screen by arranging that each of the surfaces of the focusing screen, which are provided with different structures, delivers a specific portion of the refractive power. It is advantageous to provide the surface, which serves simultaneously as focusing plane, with directionally oriented raster structures, for example with cylindrical ring microraster structures and wedge flank slopes defined on one side.

Title: Circuit arrangement for the control of a brake system with wheel slip control
Inventor: WUPPER HANS
IPC: B60T8/70
Filed: 1984-08-16
Abstract: A circuit arrangement for the control of a brake system with wheel slip control has wheel sensors (1) and electrical circuits (2-9) for the processing and logical connection of the sensor signals. Brake pressure control signals are generated, by means of which the brake pressure changes in the wheel brakes can be controlled as a function of the wheel rotation behaviour and the speed of the vehicle. The response or the use of the control and various control phases is thereby a function of deceleration, acceleration and/or slip threshold values and also of the variation of the wheel deceleration and/or acceleration (vR) overtime, which variation can be evaluated as an additional control criterion. The response threshold of the wheel deceleration (SW1) is lower than the maximum possible vehicle deceleration and lies, for example, between 0.3 and 0.6g. <IMAGE>

Title: Probe for measuring the throughflow of media such as gases, vapours or liquids
Inventor: MENG KLEMENS
IPC: G01F1/46
Filed: 1984-10-02
Abstract: Probes for measuring the throughflow of media such as gases, vapours or liquids are required in many application areas. The prior-art probes essentially comprise tubes which are provided with measuring openings and into which two small, thin tubes are pushed which interact in a particular manner with the measuring openings. As a result, there is a high susceptibility to damage and need for repair.   In order to provide a probe which does not need to be repaired much and has a long service life, it is proposed that the probe element be designed as a solid bar which has two longitudinally running bores, that one bore extend from the bar end in the region of one connection to all the measuring openings on one side and be connected thereto by transverse bores, and that the other bore extend from the bar end in the region of the other connection at least as far as the central measuring opening on the other side and be connected thereto by a transverse bore.

Title: Grease gun with a high-pressure space
Inventor: DENNERLEIN MANFRED
IPC: F16N3/12
Filed: 1984-12-03
Abstract: There is a grease gun in which a cover 4 of a grease container 1 forms a high-pressure space 15 in which a plunger 6 can be displaced and which is connected to the container 1 via a single opening 18. It is desirable here, due to the fact that there is only one opening, to avoid the occurrence of only apparent lubrication. This is achieved by virtue of the fact that the single opening 18, which is provided with a non-return valve 19, is arranged at that end of the high-pressure space 15 which lies opposite a hand lever 7 and the plunger 6 is surrounded in the region of support by an elastically compressible sealing ring 16 and an adjusting screw 17 which compresses the sealing ring. Grease can escape from the high-pressure space only via a lubricating nozzle 14 and the sealing ring 16 is adjustable and easy to replace. <IMAGE>

Title: Manually movable transport cart
Inventor: WANZL RUDOLF
IPC: B62B3/14
Filed: 1984-12-14
Abstract: In the case of the transport cart disclosed in the original application P 3405154.6 it is generally not possible for reasons of space to carry along a child in the basket. The proposed transport cart (1) avoids this disadvantage in that the swivel axis (19) of the basket (9) is arranged between the two pushing bows (7, 7') and the basket (9) is additionally supported by its end (11) which is the most remote from the swivel axis (19) against the pushing bow (7') associated with this end (11). By means of this arrangement, the forces occurring on loading can be more effectively used and at the same time the contents of the basket increased. <IMAGE>
