Title: Device for the production and mounting of a dental laboratory working model of the jaw
IPC: A61C9/00
Filed: 1981-02-03
Abstract: The invention relates to a device for the production and mounting of a dental laboratory working model of the jaw to be made on the basis of an individual jaw impression, comprising an upper part serving as a lost, sawable model carrier and a reusable lower or base part which can be releasably connected to the upper part. The upper or model carrier part is provided on its underside with a cylindrical attachment by which it can be inserted into a circular recess in the lower or base part so as to bear against a wall of the circular recess, the mutually contacting cylindrical surfaces of the upper and lower parts being clampable in an easily detachable manner in the inserted state by means of a locking or clamping device provided in the circular recess of the lower part. The cylindrical surfaces which come to bear against each other on insertion of the upper part into the lower part have interacting engagement means, for example in the form of complementary vertical toothings for the azimuthal positioning and/or securing against rotation of the two parts. The clamping device is a resilient strap retainer with a turnbuckle provided in the circular recess of the lower part which comes to rest in the open state automatically against the outer wall of the circular recess under the action of its intrinsic resilience, whereas in the closed state it comes to bear around the outer wall of the cylindrical attachment of the upper part and presses the latter firmly against the inner wall of the circular recess of the lower part. The two parts of the unit according to the invention can be assembled and disassembled in a simple manner and can be positively and non-positively connected to one another in the assembled state. The model, which is separated into individual sectors in the detached state of the upper part with the jaw model produced thereon by vertical saw cuts so as to meet the requirements of dental laboratory work, can be assembled in a simple and quick manner by re-inserting it into the lower or base part in a relative position corresponding exactly to the original, unsawed state of the model and can be firmly held in this state by closing the clamping device.

Patent DE-3115082-A1 (DE)
Title: Wheel which can be driven in four ways
Inventor: NEUDORF REINHARD
IPC: B62M1/12
Filed: 1981-04-14
Abstract: Locomotion means propelled by human muscle power hitherto have only ever utilised arms or legs as driving means: cf. bicycles and pedalos, on the one hand, wheelchairs and canoes or rowing boats on the other. The patent applied for here is intended to make use of the muscle power of all four limbs at the same time for the drive of wheeled vehicles. This is brought about by attaching an additional pedal and chain system in the front part of a conventional bicycle or pedalo. This additional driving system is moved by the hands. Hand pedals and handlebars are integrated to form a unified crank. In order when making steering movements to avoid a collision between front-wheel chain and bicycle frame, the upper connecting rod of the frame is led to the front wheel above the steering/pedal crank, and the lower connecting rod from the side, in each case using a hook piece projecting beyond the chain radius. The additional front-wheel drive is only possible on straight stretches. The system can be used in bicycles, tandems, tricycles, boats, planes using a combination of gliding and propeller drive and optionally rail vehicles. In some forms of use (tandem, rail, boat), all four pedals can be connected directly to a single chain etc.

Title: Method and device for interferometric thickness measurement
Inventor: BAYER THOMAS
IPC: G01B11/06
Filed: 1981-09-17
Abstract: For the purpose of interferometric measurement of the thickness of a varying layer (10) made from opaque material, use is made of a reference beam (J2) which is reflected at a point of the opaque material which is protected against etching by a transparent layer (11). This reference beam is polarised in the plane of incidence, and is directed onto the transparent layer at the Brewster angle ( theta b). The measuring beam (J1) is polarised at right angles to the plane of incidence and is directed alternately onto the etched part of the opaque material and onto a point of the transparent layer, in order to determine the instantaneous thickness (tm) of the transparent layer (11), which is likewise etched. The instantaneous etched depth (ts) of the opaque material can be determined from the results of the two measuring steps. <IMAGE>

Title: Continuous-airduct storage unit
IPC: E21F1/06
Filed: 1983-01-14
Abstract: An airduct system which can be used in particular in mechanised roadway driving underground can be extended virtually continuously in accordance with the requirements and without great effort, since the storage unit furnishing the airduct material is in each case formed by the last airduct. For this purpose, the airduct end to be coupled is pulled through the pushed-together airduct or the pushed-together airduct part beyond the connection ring and is then attached or coupled to the existing airduct system. To extend the airduct system, it is merely necessary to release the free end ring and to lay it together with the pushed-together airduct part in the direction of the mine air. Here, this movement is assisted by the mine air itself.   <IMAGE>
