Patent DE-2451333-A1 (DE)
Title: Photoelectric production of position change signals - is conducted at carrier frequency using double beam system with image formers at different phases
Inventor: HOCK FROMUND DIPL PHYS
IPC: G01D5/38
Filed: 1974-10-29
Abstract: The method and arrangement for photoelectric production and evolution of position changing signals at the carrier frequency involves:- a light source, a collimator, mass simulator, object surface, objective, image former objective, grating, component pictures and two receptors. The signals are then processed in elements to be displayed in the position value indicator. With laser beams this results can be achieved without the reproducing optics. A pair of opposite frequency signals are produced which are shifted by the measuring process so that with double sensitivity separate production of reference signals is not required.

Title: Regulated current supply with internal load stage - to generate control proportional to output current with filter circuit included to minimise effect of rapid fluctuations
Inventor: PREIS JOSEF DIPL ING
IPC: H04B3/44
Filed: 1975-04-30
Abstract: An output load stage built into a current supply unit provides a current inversely proportional to the variation in external load current. A proportional voltage signal is generated to control the regulating amplifier. The main regulating amplifier controls an opto-electric isolator connected to a regulating converter coupled to the input current supply. The internal load stage consists of two transistors and a resistor coupled across the output terminals. Variation in output current operates over a voltage divider to provide a voltage that is compared with a reference in a second amplifier. The difference controls the transistors to maintain output voltage and current and input current essentially constant. A filter stage operates to minimise the effects of rapid changes in output current.

Title: Flue gas ejector in chimney stack - utilises convection to draw cool air through side vents
Inventor: HERTEL WILHELM DIPL ING
IPC: F01N3/05
Filed: 1975-08-19
Abstract: The ejector is operated by flue gas and utilises the energy in the rising flue gases. This energy is supplied to blowers for ventilating purposes. This saves energy in blower motors and reduces blower plant requirements. At the top end of a flue gas duct there is an expanded flue gas duct with an air gap. Air is drawn in as a result of the ejector suction effect. This air movement generated is used for cooling of air coolers and it can be used for ventilating rooms or sections of plant. The ejector is fitted at the top end of the flue gas duct or chimney stacks in order to ensure that the temperature does not drop below the dew point.

Title: Tank downpipe assembly for sedimenting liq. - extends vertically to discharge head with faces imparting coaxial rotary movement
Inventor: TVEIT OEYVIND
IPC: B65D88/54
Filed: 1975-11-29
Abstract: The downpipe assembly is for the delivery of liquids to the base of a tank, particularly one transporting those such as phosphoric acid, which have to be kept agitated to avoid sedimentation. It comprises a vertical downpipe (23c) connected at the upper end to a pressure source, and with a discharge head (40) at the bottom immediately above the tank floor. The head has fixed guide faces (41a, 43a) directing the flow of liquid at a predetermined angle to a plane running in the lengthwise direction of the tank floor, so that the liquid has imparted to it a rotary movement coaxial to the pipe. The guide faces can run first in a curve from the vertical to the horizontal and then in one in the horizontal plane extending initially in the radial direction.

Title: Vehicle head lamp wiper device - has lamp screen with wiper motor fitted centrally to power rotating wiper blade
Inventor: PAHLKE WERNER
IPC: B60S1/60
Filed: 1976-01-03
Abstract: The headlamp for vehicles has built in scree wiper. On the convex curved front screen (10) of the headlamp is fitted a correspondingly shaped wiper blade (12). The wiper blade (12) is fitted by a central shaft (14), which passes through the lamp screen (10) to an electric motor (16) fitted to the rear of the screen. The wiper blade (12) is turned in a continuous motion so that a circular area of the screen is kept continually clean. Owing to the small size of the electric motor and its central position in the lamp the beam of light is hardly affected. By locating the wiper motor in the screen, complicated lever arrangements requiring special assembly and space within the vehicle body are unnecessary.

Title: Profiled wooden battern groover and plane pressure shoe - has adjustable vertically movable lamellae in frame
Inventor: JURISCH KLAUS DIPL ING
IPC: B23Q3/00
Filed: 1976-04-22
Abstract: The pressure shoe is mounted on a grooving and planing machine. The machine is used for making, and working on, profiled wooden battens, where workpieces are held vertically and horizontally aligned for conveyance to the blade shafts behind the profile shaft.

Title: Removing contaminants from liquid coolant - using combined effect of electrophoresis and electrolysis
Inventor: SHETTEL DON L
IPC: B01D17/02
Filed: 1976-10-04
Abstract: Electrically charged contaminants are separated from an electrically conductive liquid by passing the liquid through an electrically charged cell connected to a DC power source so that alternate surfaces are positively charged and the other surfaces are negatively charged. The charged contaminants electrophoretically migrate towards the surfaces and agglomerate at the same time as minute gaseous bubbles are generated at the cell surfaces. The bubbles are floated through the agglomerated contaminants, part of the agglomerated contaminants being entrained in the bubbles.

Title: Vinyl chloride prodn. from acetylene and hydrogen chloride - diluted with inert gases, in reactor with conical catalyst bed
Inventor: GATTYS FRANZ JOSEF
IPC: B01J8/02
Filed: 1976-10-13
Abstract: Prodn. of vinyl chloride (I) comprises reacting acetylene (II) and HCl diluted by inert gases, in a lattice reactor. Pref. the HCl reactant comprises combustion gases from Cl2-contg. substances and pref. contains 5-20, esp. 8-12-vol.% HCl. A reactor for this process comprises a catalyst bed the cross-section of which changes conically in the direction of flow of the gaseous reactants, and the outside of the reactor defines an angle (alpha) of ca. 15 degrees with the longitudinal axis. Opt., at intervals, the gas direction is reversed for a short time. Gases of low HCl content are economically utilised and less HCl is needed. The inert gas component remove the heat of reaction so no additional cooling is needed. A more uniform reaction over the whole catalyst bed is achieved with reduced migration of HgCl2.

Title: Prefabricated building element form locked connection - has end reinforced bars with thrust force transmitted by composite profiled plates which interlock
Inventor: BORSDORF HEINZ DIPL-ING
IPC: E04B1/21
Filed: 1977-01-04
Abstract: The form-locking connection is esp. for rigidly joining prefabricated building elements, of the same or different materials. They have hollow claw-shaped profiles (3) across abutting surfaces, with slits. Force flow across the joint is effected by end-reinforced connecting bars (6, 7). Tension stress on the claws is passed to mortar (5) cast in them and hardened, while impact forces are led into the bars' end reinforcements. Thrust force transfer involves composite plates, with elevations and depressions, interlocking together and pressed into each other by pressure which checks normal movement under thrust. These profiled plates and/or thrust battens are set at an interval, the intervening space being filled with shear-resistant mortar.

Title: Plasma melting furnace fitted with induction coils - using three phase travelling magnetic field for stirring molten metal
Inventor: EGUCHI ISAMU
IPC: H05B6/34
Filed: 1977-02-25
Abstract: Plasma furnace metling crucible below burner(s) is surrounded by several separate induction coils connected to a multiphase power supply so that a travelling magnetic field is created in the crucible along the common axis of the coils. The pref. electric circuit uses three induction coils connected to a three-phase power transformer via a phase change switch which alters the direction of stirring of the melt; the transformer is pref. also connected to a frequency converter, so that the induction coils may be fed by a single phase high frequency supply which does not include a travelling magnetic field; and switches are provided so that either system may be used. The travelling magnetic field produces pronounced stirring of the melt so the surface heating due to the plasma burner(s) is quickly circulated through the entire melt; the induction coils also provide heating energy.
