Patent DE-3315732-A1 (DE)
Title: Car cradle for tilting passenger cars
Inventor: REHAK JAN
IPC: B60S13/00
Filed: 1983-04-25
Abstract: In order to facilitate work on the underside of passenger cars, lifting stages or pits have been used hitherto. This however had the disadvantage that one had to work upwards, as a result became tired and therefore did not carry out the work as carefully. In addition, often when doing welding operations or applying underfloor protection, much material fell onto the face and body, which in turn led to many industrial accidents such as burns, blinding of the eyes etc. This can all be prevented by the way of working with the "car cradle for tilting passenger cars". In addition, this invention facilitates work on the underside of passenger cars to a considerably greater degree than for example a lifting stage ever could. The particular structure consisting of two metal carriers which are hooked with a flange for screwing onto the wheel-free wheel hubs permits a passenger car to be tilted into a lateral limit position of 90 DEG  without particularly large expenditure of force and holds the passenger car there in a secure hold.

Title: Trailer coupling for vehicles
Inventor: ROTHE WOLFGANG
IPC: B60D1/52
Filed: 1983-05-13
Abstract: The invention relates to a trailer coupling for vehicles, in particular for motor vehicles which consists of a downardly open housing which is arranged in a cross member and of a ball neck which is provided with a coupling ball, can be inserted into the housing and detachably locked thereto, the locking mechanism being formed by an eccentric clamping device whose eccentric can be rotated while connecting at least one handle by means of a shaft and the eccentric being lockable with the engagement of a spring-loaded securing pin into a bore of the said eccentric. According to the invention, an advance angle of rotation  alpha  which permits a relative rotation of the shaft with respect to the eccentric is assigned to the angle of rotation serving to actuate the eccentric, the said rotation leading, by means of a steeply threaded region of the shaft which interacts with the eccentric, to an axial displacement of said shaft which is utilised to transfer the securing pin into its unlocked position.

Title: Apparatus and method for producing boreholes in the ground in direct proximity to obstacles adjacent to the borehole
IPC: E21B7/00
Filed: 1983-07-21
Abstract: The apparatus consists of a mast (1) arranged on an excavator (2) and having a guide rail (3) on which two rotary drives (4, 5) are arranged in a displaceable manner one above the other for driving a casing tube (13) and a drilling tool (12) working in the protection of the casing tube (13). The rotary drives (4, 5) are driven by high-torque motors (14, 15) without speed reduction so that small slewing rings can be used. This enables casing tubes (13) of small diameter to be used in direct proximity to an obstacle. Through the use of an auxiliary borehole it is possible to use single-section casing tubes (13), corresponding to the length of the mast (1), and single-section drilling tools (12). <IMAGE>

Title: Series metering system for concrete works
Inventor: ANDRIESSEN HANS
IPC: B28C7/08
Filed: 1983-09-22
Abstract: In a series silo system designed as a transport unit for the dynamic storage of the defined allocated amounts of a plurality of different bulk material components for a mixture of bulk material, the individual bulk material components being poured, on both sides of the series silo system, into boxes separated from one another by box walls, from which boxes the bulk material components are conveyed to silo pockets arranged in a series behind one another at a distance from the ground, the boxes and silos arranged together in pairs form a discrete storage space in each case. A scraping mechanism is provided in the region of the series silo system, with which the bulk material components are conveyed out of the region of the boxes into the region of the silo pockets. This design means that the series silo system does not have to be fed with a bucket wheel loader, as has hitherto normally been the case. Scraper conveying is moreover significantly quieter and more economical. <IMAGE>

Patent DE-3406366-A1 (DE)
Title: Base longitudinal substrate for linear potentiometers and process for its production
Inventor: DIETRICH FRANK DIPL ING
IPC: H01C1/012
Filed: 1984-02-22
Abstract: Process for producing a base longitudinal substrate in the case of linear potentiometers and base longitudinal substrate produced by the process, on which a collector run and/or resistor run are applied, preferably in the form of layers of conductive plastic. Directly during the production of the base longitudinal substrate, a carbon fibre roving is drawn into the plastics profile of the said substrate together with glass fibre bundles reinforcing the said profile, in such a way that the said roving is arranged in the finished profile flush with the surface in the longitudinal extent, at least in the region of the collector run. The incorporated carbon fibre bundle forms a smooth transition to the adjoining parts of the profile and can be used directly as a collector run or as a support for the layer of conductive plastic for the collector. In a development, the layers of conductive plastic with an identical resin base are applied directly in relatively great layer thicknesses to the plastics profile.
Patent DE-3406507-A1 (DE)
Title: Interference/absorption silencer system with simultaneous catalytic afterburning for internal combustion engines
Inventor: ROESSLER PETER
IPC: F01N1/06
Filed: 1984-02-23
Abstract: Starting from the realisation that in all hitherto known silencing systems for internal combustion engines, the silencing and the catalytic afterburning take place in two systems arranged in series, the object according to the invention is achieved by virtue of the fact that silencing and afterburning can take place in one container, the sound absorber used also taking on the task of splitting the NOx.   By selection of the mesh width and of the diameter of the wire in the longitudinal and transverse direction, the rolled welded lattice introduced into the container can be matched to any frequency response of internal combustion engines. By dividing the sound absorber into individual sections, it is possible to keep down to a minimum the surface area necessary to initiate the chemical reaction and thus to keep down to a minimum the costs for the catalyst. The spent catalyst can be removed from the container, replaced by a freshly coated catalyst and the spent catalyst recoated. The container and the sound absorber are manufactured from chrome nickel steel and, as a result, the environment is no longer polluted by spent sound absorption systems of motor vehicles.
