Title: Prism application for interference figures - used in holographic interferometer with two prisms of different refractive index
Inventor: ZIMMERMANN WALTER DIPL PHYS DR
IPC: G01B9/02
Filed: 1974-04-25
Abstract: Application of a double prism, including Wollaston prim, for holographic production of an underground interference band system in bolometers with the double prism in the area of a diverging or converging beam. The double prism is moved between successive exposures of the hologram plate in the direction of the axis of the interferometer. A similar functioning of the prism is given e.g. by the production of the so-called 'living interferences' by means of a hologram created by a simple illumination. The second illumination is replaced by direct observation of the object in the light of the laser through the finished hologram plate during simultaneous reconstruction of the first hologram.

Title: Composite aluminium plates with fabric or mesh core - where fabric is coated to locate threads during mfr.
Inventor: WURST ROMAN
IPC: B22D11/06
Filed: 1974-11-23
Abstract: This is an addn. to 2332631, which described a process for the continuous prodn. of aluminium plates using a bath of molten aluminium and feeding a cooler substrate of woven fabric or mesh continuously through the bath. In the present invention, the novelty is that a woven fabric or mesh is employed in which the constituent parts, viz. fibres, threads or wires, are stabilised w.r.t. each other by a coating. The coating pref. consists of a plastic applied by evapn. at ca 700 degrees C. or a coating sprayed onto one or both sides of the fabric or mesh strip and allowed to solidify. When the fabric or mesh is drawn through the bath, the tension is greater nearer the sides and this results in the displacement of some of the fibres or threads. The coating is designed to hold the threads etc. in position leaving uniform cavities to be filled by the molten aluminium.

Title: FM directional radio system with RF switching - has fixed receive limiters and control signal derived by externally mixing part of input and output powers
Inventor: SEIBT EDUARD DIPL ING
IPC: H04B7/165
Filed: 1974-12-13
Abstract: The frequency modulated directional radio system with radio frequency switching has limiter cascade and a monitor for the receiver input power. A control voltage is obtained by mixing a small part of the output power with a small part of the input power in a mixer located outside the main signal path. The resulting intermediate frequency signal is then passed in the normal manner to a gain-controlled intermediate frequency amplifier. The mixer thereby forms a control signal proportional to fluctuations in the input signal despite the fact that the output signal of the limiter cascade has a constant amplitude.

Title: Electron beam welding control - for noncircular seams by superimposed deviation of actual from desired value producting beam deflection
Inventor: GROTE KARL-HEINRICH VON DIPL P
IPC: H01L21/68
Filed: 1975-02-06
Abstract: In the parent patent a laser, ion or electron beam is directed against a workpiece which is moved relative to the beam in accordance with a desired pattern. To compensate for any inertia in the workpiece motion control, the beam is deflected in accordance with the result of a comparison of a desired value with an actual value. In this addn. during a part of the operation, an intentional deviation of the actual from the desired value is generated, such that the resulting beam deflection to compensate the desired deviation produces an angle between the workpiece and the deflected beam. This removes the restriction of the applicability to circular seams and permits any desired contours to be fillet welded.

Title: Filamentary optical fibre continuous prodn. - using gaseous starting materials for core and cheaper fused granules or tubing for sheath
Inventor: DAKIN JOHN PHILIP DR
IPC: C03B37/023
Filed: 1975-10-01
Abstract: Continuous prodn. of a filamentary optical fibre, consisting of a core and sheath zone with different refractive index is carried out by fusing the starting materials in coaxial crucibles and drawing a filament through orifices in the bottom of the crucible, components forming the starting material(s) being passed into the crucible in the gaseous state according to the parent patent. The improvement comprises passing the components forming the starting material(s) for at most the innermost zone by at least the core of the fibre into the appropriate crucible in the gaseous state. The costs are reduced, since only the core is produced in highly pure form from gaseous starting materials, whilst the rest is produced from granular or tubular material. In an example, the inner crucible was charged with SiCl4, O2 and opt. dopant and the outer crucible with opt. doped SiO2 granules or beads.
