Title: Mechanism controlling support rolls in sheet of strip mill - controlling forces applied parallel to roll axis eccentrically by hydraulic cylinders
IPC: B21B29/00
Filed: 1973-07-03
Abstract: The curvature of the support roll of a four high rolling stand or of the working rolls in a two high rolling stand is adjusted by means of eccentric longitudinal forces applied to both ends of the roll. This arrangement ensures that the thickness of the rolled sheet metal or of the strip is uniform. The curvature controlling forces are applied symmetrically to the rolls. The hydraulic cylinder controlling the curvature are arranged in the bearing end plates. A set of cylinders is arranged above the horizontal centre line and another set is arranged below the horizontal centre line of the rolls. At the ends of the roll are arranged reaction plates which are connected by longitudinal stays. The bearing end drive pin passes through this plate with clearance. The hydraulic cylinders are arranged between this reaction plate and the shoulder of the roll. Vertical rolling forces are not affected by this arrangement.

Title: Coupling for separate hyperfrequency channels - minimises group velocity distortion with variable number of cavity filters
IPC: H01P1/213
Filed: 1974-01-17
Abstract: Coupling of centimetric frequency channels, minimising the group propagation velocity distortion which can occur when this is attempted without the use of highly selective filter circuits and the consequent increase i equipment volume. Input frequencies enter the multiplexing system through two filters into a waveguide sharing a common wall with a parallel guide ultimately reaching a common antenna.

Title: Decoration of metallic surfaces - by polishing through the holes in a protective mask
IPC: B44C1/00
Filed: 1974-02-01
Abstract: In a method for decorating metallic (esp. stainless steel) surfaces, the surface is first given an initial polish, and is then covered with a protective film. Part of this film is then removed with a heated element or with a pointed tool, and the exposed metal polished in a different way. Designs and characters can easily be produced on stainless steel, enhancing its decorative qualities. In an example, a sheet of stainless steel is covered with a film of polyethylene 100 mu thick, on which the contours of a design are traced. The areas enclosed by these contours are removed with an electric heater, and the steel surface thus exposed is repolished with a rotary brush impregnated with abrasive grains. The remainder of the film is then removed.

Title: Automatic focussing system for laser beam on to moving object - has out of focus detector of beam of surface producing signal in feedback to correct
IPC: G02B27/40
Filed: 1974-12-03
Abstract: An automatic focussing system with a light source and an optical system. The light from the laser source (31) is focussed onto the measuring surface (36) of the moving object (6). There is an optical detector (38) on which the light that is either transmitted or reflected by the object is focussed by the optical system. Any out of focus of the optical system is detected to generate a signal which is fed back to the control circuit. The defocussing causes oscillation about the optical axis at a certain frequency. These signals and those of the optical system are both fed to a synchronising rectifier of the same frequency components to detect the extent of defocussing as a function of the modules value of the output.
