Title: A tie holder with independent and separated-off hanging places intended in each case for only one tie
Inventor: RADAKOVIC SVAETOPLUK
IPC: A47G25/74
Filed: 1989-01-04
Abstract: The individual hanging places are situated on individual horizontal supporting parts located at a certain distance in parallel from a base plate common to at least one row of supporting parts or from the wall or the wardrobe door to which the tie holder is fastened, and ordered in at least one or more, likewise parallel rows. These supporting parts have a cylindrical or square or some other suitable cross-section, and may be parts, separated off for example by separating elements, for example by separating discs, of a common horizontal support, or may be parts of independent supporting elements.

Patent DE-3926255-A1 (DE)
Inventor: BERTAGGIA JOSEF
IPC: E04D5/14
Filed: 1989-08-09
Abstract: The fixing device consists essentially of a fixing element (14), which has approximately the shape of a nail, and of an elongated screw (10), which continues the fixing element axially. The head (15) of the fixing element rests on the water-impervious sheet (13), while the screw penetrates the insulating layer and is screwed into the supporting trapezoidal plate (11).

Title: Reducing free halogen concn. in upper atoms. -  by distributing alkali metal or alkaline earth metal from module to form cloud over wide area
Inventor: LAUMANNS CARL-GEORG
IPC: B01D53/68
Filed: 1990-10-11
Abstract: Redn. of the concn. of free halogens in the upper atmos. is carried out by releasing alkali(ne earth) metal from a distribution module passed into the region of the upper atmos., so that a cloud of (almost) atomic metal is distributed over a wide area. The metal is pref. dispersed thermally and the ejected vapour provides jet propulsion energy for the module, whilst the jet is split up and dispersed over a wide area. Thermal dispersion pref. takes place in a combustion chamber, the exhaust gas from which acts as propellant for the module and carrier for the alkali(ne earth) atoms. A suitable laser beam sent from the ground into the flight path of the module is used to decompose halohydrocarbons and enrich free halogen in the flight corridor region. The characteristic spectrum of the alkali(ne earth) metal is measured from the ground for optimum remote control of the module. USE/ADVANTAGE - Redn. of the free halogen concn. reduces damage to the earth's ozone layer

Title: Granular limit Josephson contact element formed on even substrate - has deepened groove-type formation in substrate upper surface acting as granular limit-inducing interference profile formed by two curved lateral flanks
Inventor: HILLENBRAND BERNHARD DIPL PHYS
IPC: H01L39/24
Filed: 1991-03-25
Abstract: The deepened formation (15) in the substrate (2) is formed by etching, having a max. depth of e.g. 100 nm. The two arched lateral flanks (16, 17) of the groove-shaped deepened formation evolve on their long side edges (16a, 17a) continuously, i.e. "cleanly" into the top surface (2a) of the substrate (2). For this, the intersection lines of the flanks must have adequately large curvature radii in order to prevent the formation of granular limits during subsequent lining with high temp. superconductor material. The flanks of the deepened formation have such as max. rise that their normals (N1, N2) enclose an angle (alpha) pref. between 40 and 90 deg. The substrate top surface (2a) is provided with a thin diffusion-inhibiting intermediate layer, on which is applied the high temp. superconductor material. ADVANTAGE - Interference profile is formed in substrate top surfaces as groove-shaped deepened formation.

Title: Mfr. of endless steel belts - ensuring uniform stressing of the belt material
IPC: B23K33/00
Filed: 1991-04-09
Abstract: The method for mfr. of endless steel belts uses an installation consisting of two parallel-axis drums (2,3) of the same dia., with one of the drums fixed in position and the other adjustable. The ends (1,12) of the belt material are clamped by means of tensioning devices (13,14) which are adjusted to produce a given preliminary tension in the material. The belt ends are then held by clamping bars (27), and the preliminary tension is removed. The adjustable drum is displaced to bring the belt ends into a position where they are cut by a shear blade and then welded together. USE/ADVANTAGE - The invention can be used to mfr. endless belts used in certain types of continuous-action presses. It simplifies the mfg. process, ensures uniform stressing of the belts and hence potentially stronger welded joints.
