Patent DE-3225723-A1 (DE)
Title: Frustoconical wedge comprising three segments for prestressing cables
IPC: E04C5/12
Filed: 1982-07-09
Abstract: The invention relates to a frustoconical wedge for prestressing cables, with which three prestressing cables can be anchored in a conical bore of an anchor body. The wedge has an axial channel for injecting cement mortar or for inserting the hollow needle of a grease gun. It is advantageous, with a given anchor-body area, to be able to anchor more cables than previously. The deflections of the cables are substantially reduced. One wedge for three cables is more economical than one wedge per cable. The wedge permits improved injection of cement mortar with posttensioning tendons and cavity-free grouting of the anchoring region with untensioned tendons.

Title: Device for tightening, in the event of a vehicle collision, the seat belt which has already been put on.
Inventor: OEHLERKING CONRAD DIPL ING
IPC: B60R22/195
Filed: 1982-09-04
Abstract: In a device for tightening the seat belt when it has already been put on, in a vehicle, in particular a passenger car, against the body of a vehicle occupant seated on a vehicle seat, the vehicle seat is to be held so as to be displaceable with respect to the vehicle frame, on which the seat belt is held, by the inertia forces occurring in the event of a vehicle collision for the purpose of tightening the belt in the direction of travel. In order to achieve a belt tightening device which is as simple as possible and acts automatically, it is proposed for at least one end (5) of the seat belt (2) to be held at one end (11) of a preferably two-armed lever (10) which can be swivelled about a centre of rotation (13) which can be connected to the vehicle frame (9), the other end (12) of said lever being connected to the seat (1) in such a way that in the event of a displacement of the seat brought about by inertia forces, the lever is swivelled in order to tension the belt. <IMAGE>
Patent DE-3236212-A1 (DE)
Title: Centring chuck for rotationally symmetric parts in metrology and test engineering
Inventor: BENKERT STEPHAN DIPL ING
IPC: G01M13/00
Filed: 1982-09-30
Abstract: The centring chuck described above for rotationally symmetric parts in metrology and test engineering is especially distinguished by the fact that statically determined adjustment, support and centring is made possible by the 3-point support and 3-point clamping/centring of the test piece. At the same time, only one and the same chuck is required for internal and external mounting of the test piece so that stockkeeping and costs are considerably reduced. The type of construction is compact and can be exactly defined with regard to manufacture and mode of operation. The holding forces for the test piece are adequate and the locking is guaranteed. Adjustment in the range of the min. and max. envelope circles which define the clamping range of the chuck is quick and problem-free as a result of appropriate transmission in the drive system. Thus, in the present case, about seven turns of the key at the adjusting pinion are used in order to cover the diameter range of 20 to 120 mm, which proves to be a substantial advantage with regard to conventional manual and power-operated chucks, since the time needed there is much greater. This chuck is deliberately not conceived as a clamping chuck and primarily has a centring function with a nonetheless adequate holding force for driving the test piece during the measuring operation. At an induced torque at the adjusting pinion of about 25 daNcm, a minimum holding force at the centring and holding pins of (in the present case) about 18 daN is obtained. This force is ...

Patent DE-3248703-A1 (DE)
IPC: C12M1/113
Filed: 1982-12-30
Abstract: The method is used for the continuous production of a biological humus-forming fertilizer free of germs and medicinal residues, from animal and agricultural waste, and biogas by bacterial fermentation. The treatment for the preparation and anaerobic bacterial fermentation of the starting material mixed with starting material mixed with a liquid into a continuous and uniform flow is achieved in two steps. In the first step, life conditions are created within the suspension which are best adapted to cultures of mesophilic bacteria causing a hydrolysis and acidification of the starting material, particularly by heating at about 30<o>-40<o>C and, at predetermined time intervals, first part of the bacteria-containing liquid and at the end of the treatment optionally the other part is removed from the suspension and is added to the new starting material to be introduced and/or to the suspension. In the second step, the product released preferably partially from the liquid of the first step is mixed with the bacteria-containing liquid extracted from the suspension in the second step and life conditions best adapted to the cultures of thermophilic bacteria achieving the fermentation are created within said liquid, particularly by heating at a temperature of about 50<o>-60<o>C. The gases generated in both steps are sucked and collected; at least one portion is divided into separate jets and introduced into the suspension, the remaining being separated into CO2 gas and CH4 gas, the first one being divided into separate jets and again introduced into the suspension, the second one being used to cover the general energy requirement for implementing such method up to the obtention of the final product. The plant for implementing such method comprises two covered vat-like containers (11, 12) of which the bottom (15) presents a continuous slope of at least 2% from the loading end to the discharge end.
