Patent DE-2945251-A1 (DE)
Title: Measuring level of liq. steel in ladles etc. - using laser beam directed at surface at angle to axis of imaging system
Inventor: BOHLAENDER PETER DR
IPC: G01S17/46
Filed: 1979-11-09
Abstract: A method of determining the position of the free surface of the steel involves illuminating it and forming an image of the illumination on a photoelectric receiver. It is improved wrt. similar methods to enable its use with surfaces much larger than the beam cross-section and whose position varies in the direction of propagation of the beams. A laser beam is used and is inclined at an angle to the axis of the imageing system. The beam is directed at a surface region perpendicular to the optical axis at a point which is at the correct temp. to radiate in the same visible wavelength region as the laser. The reflected and radiated light from the surface passes to the receiver via a narrow band filter passing the laser wavelength.

Title: Electric stamping machine - has hydraulic control system for piston, and connecting rod with top and bottom die
Inventor: ISHIHARA MASAMITSU
IPC: B21D19/00
Filed: 1979-11-28
Abstract: The machine has a stamping unit with removable facing top die and bottom die, enclosing a work piece, and a hydraulic system. The system contains a cylinder connected to both dies. The piston (14) in the cylinder is displaced by a pump (21), which is driven by an electric motor. The system also contains a stroke limitation valve (88), which opens after a piston stroke, and permits escape of the pressurised hydraulic fluid. The stamping unit has a connecting rod (104), removably fastened to the piston rod (72). The front end of the connecting rod carries the top/bottom die (114,120), while the second die is displaceably fastened to the centre of the rod. A stop (118) behind the second die limits its movement.

Title: Bowden cable assembly with improved flexibility - includes balls and spacer sleeves for within outer sheath to locate inner cable
Inventor: ECKHARDT WILHELM
IPC: F16C1/20
Filed: 1979-12-01
Abstract: A Bowden cable assembly includes spherical balls (5) which are provided with a hole through the centre. The balls which are located inside the cable sleeve, are spaced by tubular sleeves (9) whose bore is larger than the cable thickness. The cable is able to slide inside the spacers and the balls, thus the flexibility of the cable assembly is improved. The fitting (6) on one end of the cable is provided with a screw sleeve (7,8). The sleeve adjustment controls the axial movement of the spacers and balls, and thus the flexibility of the cable.

Title: Quantitative refractive index inhomogeneity measurement - by measuring deflections of beams passing through different regions of component blanks, for UV visible or IR regions
Inventor: KUTTNER PAUL DR
IPC: G01N21/41
Filed: 1980-01-30
Abstract: A method of quantitative measurement of inhomogeneities in refractive indices of optically transparent, plane parallel bodies in the ultraviolet, visible, and infra-red spectral regions is esp. applicable to blanks for manufacture of expensive optical components. It gives precise measurement results, esp. in the infra-red region, with relative economy. A narrow parallel beam is passed through several regions of a plane parallel body. The deflections associated with the individual regions are measured from the intensities at the line image edges. The linear image edges are held linear by suitable arrangement of the aberrations of the optical elements affecting the beam and of the plane of adjustment. The deflection data is evaluated using data processors and represented in quasi-three-dimensional form.

Title: Electroforming of shear foils used in dry electric razor - where foil has raised projections so it slides smoothly over human skin
Inventor: BLUME FRIEDRICH
IPC: C25D1/08
Filed: 1980-01-31
Abstract: A metal plate (I) is covered with a mask corresp. with a desired pattern or sieve holes, thus leaving webs, which are electroplated to obtain an intermediate metal foil (II) contg. small solid particles (IIa) providing raised zones in foil (II). A shear foil (III) is then formed on foil (II) by electrodeposition; and particles (IIa) in foil (II) result in a shear foil (III) possessing projections. Foil (III) is ripped off foil (II). Foil (II) is pref. made using an electrolyte soln. contg. a dispersion of spheroidal particles (IIa), 5-20 microns in dia., and a second intermediate foil (IIb) may be deposited on foil (II) before the electrodeposition of foil (III). The projections on the shear foil (III) ensure that the latter glides smoothly over greasy or moist skin.

Title: Process for the preparation of homopolymers or copolymers of vinyl chloride
Inventor: KLIPPERT HEINZ DIPL CHEM DR
IPC: C08F291/02
Filed: 1981-02-11
Abstract: The invention relates to a novel process for the preparation of vinyl chloride homopolymers or copolymers in aqueous suspension in the presence of small amounts of gaseous oxygen, a special suspending medium combination and further conventional polymerisation auxiliaries. In this process, at least three water-soluble suspending media are employed, which differ in their dynamic interfacial tension, measured by the Traube method, as follows:     suspending medium A = from 1.0 to 6.0 mN/m,   suspending medium B = from 6.1 to 16.0 mN/m and   suspending medium C = from 16.1 to 29.0 mN/m. The polymers produced in this way are distinguished by particularly high bulk densities, good removability of the residual monomers, a favourable particle-size distribution, good warm miscibility with plasticisers, and good initial colour, as well as good processing properties during thermoplastic processing.
Patent DE-3107047-A1 (DE)
Title: Transmission stage with high output power for multi-stage digital signals with a very high baud rate
Inventor: MEYER FRITZ DR ING
IPC: H04L5/04
Filed: 1981-02-25
Abstract: In the generation of multi-stage digital signals from binary signals with a very high bit rate, difficulties occur in terms of reciprocal interference of the individual amplifier stages due to the high changeover speed; a further difficulty is created in terms of the required output power through the use of transistors with a relatively high current-carrying capacity and correspondingly high capacitance, the current consumption being relatively high in state-of-the-art arrangements. A circuit arrangement is therefore proposed which has a number of differential amplifier combinations corresponding to the number of binary signals which are to be converted, each differential amplifier combination containing an emitter-coupled differential amplifier on the input side and a base-coupled differential amplifier on the output side and the output signals of the base-coupled differential amplifiers being combined in a line transformer to form a common output signal. The arrangement according to the invention is particularly suitable for use as a binary multi-stage converter in the transmission stages of PCM systems with baud rates of several hundred Mbaud. <IMAGE>
