Patent DE-3825334-A1 (DE)
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D39/00
Filed: 1988-07-26
Abstract: The invention concerns a device for containing and holding in position specific quantities of bulk material. The device has two strips of fabric which are connected to each other to form a mat and between which the bulk material is inserted. One of the strips is designed with cushion-like protusions distributed over its surface, which are bounded by cross-pieces running in the longitudinal and transverse directions with respect to the strip and are connected to the other strip. To ensure that the device is not only easy to manufacture and easy to use, but will also hold specific quantities of bulk material permanently in position, it is proposed that the device consist of two mats (6) which are oriented at 180 DEG  to each other and positioned one on the other in such a way that the cushion-like protusions (2) of one strip (1) of the first mat (6) fit snugly into the gaps between the cross-pieces of the second mat (6). These gaps are shaped as depressions (7) to match the shape of the cushion-like protusions (2). Together, the two mats (6) hold a layer of bulk material of even thickness. In a preferred embodiment, the strips (1, 4) in the mats (3) are made of non-woven fabric and the bulk material inserted between the strips is filtration-residues (5).

Title: Cutter-hoe set for weed control and soil loosening - mechanical implements -
Inventor: OSMANN PAUL
IPC: A01B1/10
Filed: 1988-12-13
Abstract: The material and construction of the cutter hoes are the basis for producing them as a set. The cutter plates made of 0.5 mm spring steel do not allow any wider production than 70 mm for reasons of stability, and therefore the cutter-hoe types B, C and D have a widening by the amount of the dimensions of type A. The cutter bottom has a working width of 70 . 40 mm. The bottom and legs are bevelled on both sides. In types B, C and D, the cutters are arranged offset. During the work operation, one leg performs the function of precutting. Fastened to the holding frame, the cutters point 20@ forwards; the socket or pin are fastened so as to ascend at 40@. When the cutter hoe is set down, the cutter bottom rests on the ground in a position inclined at 20@ and easily penetrates when it is pulled tight. The blunting is round and amounts to a maximum of 0.3 mm. Raking examples which explain the performance and easy handling:   Type A 70 mm working width, soil-working depth 30 mm = 60 mm (two legs)   130 mm . 0.3 mm = 0.39 cm<2> material resistance,   Type B 0.69 cm<2> material resistance   Type C 0.99 cm<2> material resistance Type D 1.59 cm<2> material resistance.

Title: Torsional vibration absorber
Inventor: WAGNER BERND
IPC: F16F15/14
Filed: 1989-01-31
Abstract: A torsional vibration absorber, particularly for the drive shaft of a motor vehicle, consists of a hub (2) which can be fixed in torsionally rigid fashion on a shaft, of a rotary mass (3) concentrically surrounding the hub (2), and of a rubber-spring device (4) connecting the rotary mass (3) to the hub (2) and acting in the circumferential direction. In order to improve the guidance of the rotating mass (3) relative to the hub (2) and, at the same time, to increase the absorption capacity of the torsional vibration absorber, supporting studs (7, 8) are provided on the inside of the rotary mass (3), projecting radially inwards to an extent such that their radially inward-facing front faces (9) rest in sliding contact with the outer circumferential surface (10) of the hub (2). The outer circumferential surface (10) of the hub (2) has a circular, cylindrical form in the areas in sliding contact with the inner front faces (9) of the supporting studs (7, 8) and the inner front faces (9) of the supporting studs are matched to this shape. <IMAGE>

Title: Method of reprocessing used DeNOx catalysts
Inventor: RANLY HANS DR RER NAT
IPC: C22B30/04
Filed: 1989-02-07
Abstract: Catalysts for denitrogenation of flue gases have to be replaced from time to time because of a decline in the catalytic activity. They contain appreciable concentrations of toxic heavy metals. They therefore have hitherto had to be taken to a landfill for special waste (special waste dump). It is therefore an object of the invention to reuse the raw materials contained in the used catalyst compositions and to reduce as far as possible the compositions to be landfilled (dumped). For this purpose, the invention provides for the used catalyst composition to be milled, digested with concentrated sulphuric acid, dissolved in dilute sulphuric acid, to filter off insoluble impurities, to selectively remove the arsenic content and, after prior matching of the molar ratios to the new application, to precipitate, filter off and dry the remaining metal oxides. The invention is essentially suitable for the reprocessing of DeNOx catalysts which have been used in power station operation. <IMAGE>

Title: Mains isolator
IPC: H02J13/00
Filed: 1989-03-20
Abstract: A mains isolator is described for disconnecting electrical lines and loads from the AC supply voltage. The object is in this case to achieve complete DC-isolation of the supply network switched off, the intention also being to detect even electronic loads having relatively low demand, especially ones without a power supply unit. For this purpose, provision is made for the phase and neutral conductors of the mains supply cable to be disconnected with respect to the connection cable, in each case by one relay contact, for a floating DC voltage to be provided on the two lines of the connection cable when the connection cable is disconnected from the supply cable, and for the switching-on of a current load in the switched-off connection cable to be detected by a comparator which drives a relay after a time delay, which relay connects the supply cable to the connection cable via the two previously switched-off contacts, and for a measuring circuit to be provided which detects a current load in the downstream-connected mains supply to be switched off and keeps the relay contacts closed as long as the current load persists.

Title: Spring-loaded catch for door - has grooves in oblique end face to prevent lock from being forced open
Inventor: FRICKE KARL HEINZ
IPC: E05B17/20
Filed: 1989-05-05
Abstract: A door (1) is fitted with a lock (2) enclosed in a housing (3). The lock has a spring loaded catch (6) which can be retracted by rotating the boss (5) which is actuated by the door knob or handle. When the door is closed, there is a small gap (12) between the door (1) and the door post (7). This gap enables a thin object, such as a credit card, to be inserted and pressed against the oblique end surface of the catch and force it open. This forcing of the lock is prevented by forming vertical grooves (13) in the oblique end face of the catch. The edge of the card is gripped in one of the grooves and so prevents the catch from being forced open. USE/ADVANTAGE - Increased lock security.

Title: Device for flushing rainwater storage tank - has inner vessel which can be tipped about horizontal axis
Inventor: EGNER SIEGFRIED DIPL ING
IPC: E03F5/10
Filed: 1989-10-28
Abstract: The invention concerns a method of flushing out an empty rainwater storage tank (1). The floor (2) of the tank slopes downwards to a sump (3) with the floor of the sump (3) being below the lowest part of the floor of the tank. A vessel (5) for the flushing water is mounted near the upper edge of the tank at the end opposite to the sump (3). This vessel (5) is mounted so that it can be tipped about the horizontal axis (7). When the water level in the tank falls to the level (27) a switch is actuated and sets a pump (4) in operation to fill the vessel (5) with water fron the tank.  When the water falls to the level (22) a second switch is actuated. This switch activates a mechanism (20) which retracts the bolt supporting the vessel (5) so that it tips about the axis (7) and discharges the contents  into the tank (1). USE - Flushing of rainwater storage tanks.
