Helmut Hildebrand, Gerhard Dunker: Radiating cable having spaced radiating sleeves. Kabel und Metallwerke Gutehoffnungshutte, Smyth Pavitt Siegemund Jones & Martella, December 12, 1978: US04129841 (68 worldwide citation)

A regular, radiating coaxial transmission line is improved by covering it with an insulating coating; similar, cylindrical, radiating elements are equidistantly placed on the line and at a center-to-center distance equal to the wavelength of the center frequency of the h.f. band as transmitted in an ...

Peter Madry: Moisture proof electrical cable. Kabel und Metallwerke Gutehoffnungshutte, Ralf H Siegemund, November 23, 1982: US04360704 (41 worldwide citation)

An insulated cable core is provided with a shield made of individual wires which are embedded in a first plastically deformable jacket which carries a water vapor impermeable sleeve made of wrapped or folded metal or metallized foil or ribbon whose adjoining edges are sealed. This sleeve carries a s ...

Fritz Glander, Hermann Uwe Voigt: Grafting of silane on thermoplastics or elastomers for purposes of cross-linking. Kabel und Metallwerke Gutehoffnungshutte, Ralf H Siegemund, November 15, 1977: US04058583 (41 worldwide citation)

Granulated polyethylene is agitated and mixed with a solution of silane with peroxide, activators and anti-oxidants and at a temperature between 80.degree. to 100.degree. C to obtain diffusion of these additives into the polyethylene particles which is followed by grafting through extrusion or radia ...

Gerhard Ziemek: Filter for liquids. Kabel und Metallwerke Gutehoffnungshutte, Smyth Pavitt Siegemund Jones & Martella, September 9, 1980: US04221670 (30 worldwide citation)

The filter is constructed as a cylindrical or tapered body preferably having longitudinal grooves and ridges as flow channels, the body being made of thin metal, preferably gold plated nickel, to be self-supporting and having perforations to obtain a perviousness from 40 to 200 mesh (metric-DIN). A ...

Siegfried Fuhrmann: Fitting for conduits with corrugated tubes and hoses. Kabel und Metallwerke Gutehoffnungshutte, Ralf H Siegemund, December 20, 1977: US04063757 (29 worldwide citation)

The fitting has a main part which has two axially spaced corrugations, one for engaging the corrugations of the tube, the other engaging the hose projecting from the tube. A sleeve with outer corrugations engages the hose from the inside. Armoring is clamped separately onto the outside of the main p ...

Otto Breitenbach: Method of making a stator for linear motor. Kabel und Metallwerke Gutehoffnungshutte, Smyth Pavitt Siegemund & Martella, January 19, 1982: US04310966 (27 worldwide citation)

A long stator for a linear motor is assembled from many individual core elements provided with transverse grooves into which one places cable to be retained in the grooves so that they physically interconnect the stator elements and establish a chain-like assembly which can be, e.g., wound on drums ...
