Patent DE-3822253-A1 (DE)
Title: Tensioning device for safety belts in motor vehicles
Inventor: WINTERSHOFF WERNER
IPC: B60R22/195
Filed: 1988-07-01
Abstract: A tensioning device (1) is described for safety belts in motor vehicles. A pivot rod (2) is connected, by its free end, to a lock (6) of a safety belt. The actuating force is produced by a spiral spring (11), which permits the tensioning device (1) to be of compact construction. The belt tightening process is initiated by a sensor weight which at the same time acts as a guide body (8) for the free end of the pivot rod (2). Deceleration of the vehicle causes the sensor weight to actuate a catch (7), which, in its turn, is made by the prestressed spiral spring (11) to release the pivot rod (2) to permit a belt-tightening movement to take place. The fact that the pivot rod (2) can be rotated through 180@ results in a small modification of the path of the belt lock (6) and therefore of the safety belt at the start and end of the belt-tightening movement. <IMAGE>

Title: Composition for a biodegradable, residue-free control of varroatosis over an unlimited period
Inventor: TILLY OLIVER
IPC: A01N31/02
Filed: 1988-07-08
Abstract: Technical object and aims. The composition damages the varroa mite in such a manner that the bee colony can be considered as healthy. Chemical compositions of the prior art are highly toxic and not free from residues and can therefore only be used during limited periods. Due to its practical application (systematic composition) and its biodegradability, the author's composition has shown to be free from residues. For these reasons and because of the physical properties (evaporation), the composition can be used at all times. Solution of the problem The problem was solved by the biodegradable chemical ethanol (C2H5OH). The composition is a mixture of ethanol, solvent (water and/or honey) and an odoriferous agent (for example Spiritus Thymi). This mixture is applied to the spaces in the honeycombs by a dropwise application to the bees (see description). Field of application The composition is used in honey bees for controlling varroa disease (varroatosis).
Patent DE-3829898-A1 (DE)
Inventor: LAWSON RODNEY JAMES
IPC: H03K19/013
Filed: 1988-09-02
Abstract: The invention provides an emitter follower driver circuit for an ECL circuit in which a further transistor Q3 is provided to pull the output of the driver without requiring a power input so to do. Emitter follower Q2 acts as a push transistor to charge a capacitative load (C1) when the input to the bases of emitter follower transistors Q1, Q2 goes high. Diode 15 and transistor Q4 form a current mirror, and whilst the input remains high a current IQ flows in each branch, no current flowing into the base of Q3. When the input goes low the current flowing through each branch of the current mirror drops immediately, but because of the capacitative load the potential at the output terminal remains high. The current IQ then flows into the base of Q3, turning the transistor on which rapidly discharges the capacitative load C1. <IMAGE>

Title: Method of sealing existing landfill sites or contaminated surfaces
Inventor: OFENSTEIN JOSEF
IPC: E02D31/00
Filed: 1989-01-09
Abstract: Pipes are drawn in approximately parallel to one another under the landfill site or contaminated surface. A coulter is advanced in each case between two pipes. Sealing sheets lying side by side are drawn in between the soil layers separated by the coulter. The sheets are connected to one another in a sealing manner along their margins. In order to permit control of the proper drawing-in of the sheets and of the tight connection of the sheet webs to form a sealing layer and in addition to enable a sealing layer to be constructed which is largely insensitive to soil movements, the coulter (2) is advanced in each case by approximately the width of a sheet. The sheet web (15) is drawn in transversely through a gap space of the coulter (2). A margin of the sheet web (15) drawn in last is connected in the gap space to the free margin of the preceding sheet web. During the advance of the coulter (2), a mineral sealing mass is placed on both sides of the sheet (15) (Fig. 2). <IMAGE>

Title: Method for the production of a composite article
Inventor: WAHL WOLFGANG DR ING
IPC: B23K20/227
Filed: 1989-04-01
Abstract: In a method for the production of a composite article, a tubular component composed of high-alloy steel is first of all produced in a casting process. The internal curved surface of this tubular component is machined to size. A core element composed of low-alloy steel, the outer surface of which has likewise been machined, in this case to a certain undersize, is inserted into the tubular component and joined to it under high pressure and at high temperatures in a thermodiffusion process. In the last heat-treatment process, the tubular component is hardened, thus forming a wear-resistant shell around the low-alloy core element.
