Patent DE-3227943-A1 (DE)
Title: Rolling device for suitcases
Inventor: HUEBNER WILHELM
IPC: A45C5/14
Filed: 1982-07-27
Abstract: Since the rolling suitcase covered by the application P 3129791.9 with rollers under the case bottom has proved to be very convenient when travelling, it was time to register an embodiment additionally for the removable rollers. Such a removable roller can be manufactured more easily and adjusted in a weight-balancing manner relative to the centre of gravity of the case. With this rolling case which can even easily be steered about the centre of gravity of the case, it is possible as a pedestrian to pass through difficult traffic situations. It even provides good service during outdoor holidays. Since these are often conducted in an unrestrained manner, the roller can be exchanged for one with a wider track. This rolling case raised great interest during the initial trips due to the easy and rapid guiding of the case without effort. It makes travelling easier, provides a novel travel feeling and increases travel enthusiasm.

Title: Method and device for producing a surfboard
Inventor: FRANK DIETER
IPC: B26D5/16
Filed: 1982-10-13
Abstract: Method and device for producing a surfboard or the like with curved surface areas by cutting out of a material block by means of a cut running in a straight line transversely to the feed direction and guided along a curve (Q) in the feed direction, in the course of which, to produce surface areas running in a curve in two cutting planes intersecting at an angle to each other, the slightly elastic material block is bent against the desired curvature by the desired degree of curvature, the parting cut, straight in the longitudinal direction, is guided in a curved path corresponding to the desired curvature in the other cutting plane and then the material is returned into its initial position, the parting cut being directed along a circular path (K) with a predetermined radius (R), and deviations of the desired curvature in planes which lie in the cutting direction from the circular path (K) being produced by changing the position of the centre (S) of rotation of the radius (R) (Fig. 7). <IMAGE>
Patent DE-3238186-A1 (DE)
Title: Compound navigation method for determining the nominal position of a vehicle
Inventor: GIELEN HARALD DIPL ING
IPC: G01C21/12
Filed: 1982-10-15
Abstract: The compound calculation is carried out with a course reference device exhibiting an unknown drift (DN). Furthermore, a position is determined using as a basis an arbitrarily selected pseudo drift (DP). For determining the actual position of the vehicle, the course direction is determined by measuring the north direction after a period of travelling. From the course direction determined by means of the compound calculation, the drift (DN) of the course reference device can be determined. Using this drift and the pseudo drift (DP) and the corresponding position values (PJ, PP), the actual position (PS) of the vehicle is determined by forming a ratio.
Patent DE-3242467-A1 (DE)
Title: High-voltage switching chamber
Inventor: SLAMECKA ERNST PROF DR TECHN
IPC: H01H33/915
Filed: 1982-11-15
Abstract: As a variant of a stationary double-nozzle system of symmetrically arranged conductor material-insulating material nozzle bodies, Patent Application 3240774.2 now proposes a physically equivalent mobile double-nozzle system. This is particularly suitable for power circuit breakers having very high rated voltages. An insulating material nozzle body (4) is arranged on the closing body (12c) of a movable compression cylinder (12), and a conductive material nozzle body (3) is arranged axially opposite it on the end of a gas outlet tube (16). The gas outlet tube is rigidly connected to the compression cylinder, with the inclusion of a stationary piston (10) between the attachment and the nozzle bodies. When switched off, an annular channel (92) passes the switching gas out of the compression spaces A and B in a radially symmetrical manner to the arc-interrupting space. According to the invention, the space between the nozzles has the same quality dielectrically as a free gas path. A second free gas path, which is connected in series therewith, is located between the insulating material nozzle body and the stationary switch pieces. When switched off, an expansion space (C) is formed. The switching gas filling this space presses onto the annular piston (84) and thus supports the drive of the switch. The compression cylinder (12) and piston (10) can be designed with steps, and can also be developed into a pulse drive. <IMAGE>

Patent DE-3319891-A1 (DE)
Title: Method for the production of spontaneously crimping man-made fibres and filters comprising man-made fibres of this type
Inventor: SCHIPPERS HEINZ DIPL ING
IPC: D01F8/04
Filed: 1983-06-01
Abstract: For the production of spontaneously crimping man-made chemical fibres, it is proposed to spin together two thermoplastic polymers of the same kind, of which one is modified with rubber and has an elastic entropy deformation behaviour. In contrast to the main patent (main application), according to which the filaments are spun as bicomponent fibres by means of a bicomponent nozzle suitable for this purpose, it is now proposed to disperse the polymers in one another before spinning and to spin them by means of a spinneret for homogeneous polymers which is of simple construction. A bicomponent structure of the filaments is obtained in which the base polymer essentially forms the continuous phase and the rubber-modified polymer is present in side-to-side arrangement and/or in the form of discrete inclusions. The dispersion is dependent on the number of mixing steps, preferably static mixers, in the melt channel and the regularities of a random distribution occur with respect to cross-sectional content and geometrical arrangement in the filaments.   After drawing, the filaments develop their crimp spontaneously and are readily applicable as filter material for gases and vapours.

Title: Device for detecting the position of mobile machine units on coke oven batteries
Inventor: KRUEGER GERALD DR ING
IPC: C10B41/00
Filed: 1983-07-22
Abstract: In the operation of a coking plant, the machine units (13, 14, 15, 16) movable along the coke oven battery must, during the filling and emptying steps of a combustion chamber (11), be moved to defined working positions. For undisturbed operation, the working positions of the various machine units (13, 14, 15, 16) must be determined. For this purpose, the invention proposes to fix, along the coke oven battery, irradiated reflectors which mark the working positions of the mobile machine unit (13). The reflectors are arranged on coding plates (23) in such a way that, from their number and mutual spatial arrangement, there is an unambiguous relationship with the corresponding position number of the machine unit (13). A television camera (27) fixed to the machine unit (13) takes a picture of the coding plate (23) and passes this to a picture evaluation system (42) for determining the position number. <IMAGE>

Title: Process for heat treating fine-grain material
Inventor: HOLSIEPE DIETMAR
IPC: C04B7/44
Filed: 1984-02-20
Abstract: The invention relates to a process for heat treating fine-grain material which, following preheating in a multi-stage cyclone preheater, is further heated by additional fuel, before it is finally kilned in a rotary kiln. In this process, the additional fuel is comminuated to a particle size of a few mm and separated into a fine fraction and a coarse fraction, the fine fraction being supplied to the cyclone preheater and the coarse fraction being supplied to the rotary kiln. In this manner, even with a low degree of grinding of the fuel, good combustion of the coarser fuel particles is achieved.
