Title: Chimney inlet connection
Inventor: LAMPKA BRUNO
IPC: F23J13/06
Filed: 1987-09-24
Abstract: A chimney inlet connection (10) is made of cast iron and has an S bend. Its intake (12) forms an angle of about 45@ to the outlet (14). Two ring-shaped grooves (16, 18) are provided on the exterior, parallel to the intake (12). Parallel to the outlet (14) there is another ring groove (20), at a distance equal to the distance of the two ring grooves (16, 18). The chimney inlet connection (10) can be used for four different types of installation (normal jamb with horizontal or 45@ inlet, and jamb with brick facing and plaster, also with horizontal or inclined inlet axis). In the case of a thick chimney wall with an inlet axis inclined at 45@, the chimney inlet connection (10) will fit without alteration. For the other three cases, a section is cut off along one of the grooves (16, 18, 20). By virtue of its S shape, the chimney inlet connection only requires a wall penetration of small height. <IMAGE>

Patent DE-3742331-A1 (DE)
Title: Method for influencing the conducting properties of optical waveguides as a function of temperature
Inventor: GRUHL HARTMUT DR
IPC: G02F1/01
Filed: 1987-12-14
Abstract: The invention relates to an optical waveguide, whose sheath consists of organic material (e.g. silicone) and whose core consists of inorganic material (e.g. quartz). Since the refractive index of the sheath nM rises faster than that of the core nK in the case of cooling of the optical waveguide, both refractive indices are equal at a limiting temperature Tg. By reducing the difference in the refractive indices, the attenuation of the optical waveguide is increased. Since, therefore, there exists a defined connection between attenuation and temperature, such an optical waveguide can be applied as a low temperature thermometer or as a temperature-controlled attenuation element (switch, modulator). If only a small region of the optical waveguide is cooled and the emerging light is collected, a reversible exit coupling element results. The optical waveguide need not be mechanically manipulated in any of the applications (Fig. 1). <IMAGE>

Patent DE-3744613-A1 (DE)
Title: Winter sports apparatus
Inventor: HURTH PETER
IPC: A63C5/00
Filed: 1987-12-31
Abstract: The present invention relates to a winter sports apparatus, in which the user travels over snow slopes with the aid of at least three parallel runners, on which there may be any desired superstructure, from a simple standing board with a slip-proof covering to a seat structure. Since the standing board or the superstructure is fixedly connected to the central runner, tilting of this central runner and, via a corresponding mechanism, a parallel tilting of the other runners is also possible. The direct contact of the user with the central runner ensures rapid and undistorted transmission of information about the terrain to the user, and counteracts a soft, sticky handling performance of the apparatus as a whole.

Inventor: ROTH GERHARD DIPL PHYS DR
IPC: H01F6/06
Filed: 1989-07-15
Abstract: A superconducting intense-field magnetic coil for producing a magnetic field comprises one or more approximately rotationally symmetrical, hollow cylindrical winding regions composed of layers of windings of a current-carrying superconducting wire. Radial components of the magnetic field which produce axial Lorentz forces as well as an increase in the axial pressures in the winding layers are present in the axial end region of at least one winding region. The invention is characterized in that, in the axial end region of at least one winding region, the current density in at least one winding layer (S3, S4) is less than the normal current density in the adjacent end region, and that the maximal axial Lorentz force and the maximal axial pressure in this winding layer are therefore maintained within permissible limits.
