Title: Automatically cleaned flashing or reflector road sign - with movable cover section time switch mechanism programmed for varying conditions
Inventor: AMANN MARIO
IPC: G09F13/04
Filed: 1975-08-27
Abstract: The road traffic guiding device incorporates a movable transparent element as a dirt interceptor in front of its reflector or light aperture; a section of this element is removed from the effective visual area and replaced by an adjacent section; an electric, spring tension, or other power source is connected to the element and operated at fixed time intervals by a control device. This control device is in the form of a time switch mechanism, charged with one or more switching programmes. The programmes are automatically selected, delayed, varied, annulled or completed, by factors including air temperature, air humidity, the degree of dirt on the dirt interceptor, or any desired combination of these. This is inexpensive, and reduces the use of power, so that devices which can only be checked at long intervals can be relied on to keep the road signs operating visibly.

Title: Switching surge suppression system - is for voltage and current limited supplies with intermediate controlled current build up circuit and uses two transistors
Inventor: ARNOLD INGO DIPL ING
IPC: H02H9/00
Filed: 1975-10-04
Abstract: The system is for control of safe power supplies used in explosion risk environments. The object is to limit the capacitative current flow due to long leads on the output side when switching on. Astable multivibrator (2) has a controlling input from a divider (R5, R6) across the circuit output. The vibrator output controls a transistor (V1) shunting a capacitor (C) in series with a resistor (R3) across the supply with their common point connected to one input of an operational amplifier (3). The amplifier output controls the base of a second transistor (V2) in series with one line. With the first transistor (V1) conducting the amplifier output is practically zero and the series transistor (V2) is non-conducting. If the control transistor turns off then the capacitor (C) begins to charge giving an input to the amplifier such that the resultant output turns on the series transistor (V2) at a rate comparable to the charging rate of the capacitor thus producing a controlled voltage build up.

Title: Coating ceramic article with lacquer by electrostatic spraying - after application of electroconductive base coat
IPC: B05D7/00
Filed: 1975-11-19
Abstract: The electroconductive base lacquer (pref. contg. 2-50% of graphite) is heated after being sprayed on. The still warm body is then sprayed with a covering lacquer contg. coloured pigments and heated again. This can be provided with decorative, glossy coatings at temps. much below the high temps. necessary for the conventional glazing. (provided that the coated tiles will not be exposed to high temps. during their service life). The use of a thin base coat having a relatively high electroconductivity permits subsequent electrostatic application of a thick top coating (this cannot be achieved by the conventional method because of the low electroconductivity of the ceramic substrate). Lacquers based on polyurethanes, polyesters or epoxy resins can be used.

Title: Examination technique for moving picture - with continuous picture illuminated and image of light source focussed on a plane
Inventor: BACH GUY ROGER JULES FRANKREIC
IPC: H04N9/11
Filed: 1975-12-22
Abstract: The light beam is in the above plane periodically deflected at a right angle to the picture motion. After focussing the deflected beam is directed to a stationary photocell which converts optical into electric pulses, so that the picture is horizontally scanned in lines from top to bottom, with each line passed before the photocell. The light source (1) is followed by a condenser (2) between it and the film (3). The slightly convergent beam then passes to a semitransparent mirror, which permits the beam to continue to more lenses and a reflecting prism. On return the mirror directs parts of the light to the photocell (14). A synchronisation device connects with an external television viewer.

Patent DE-2630856-A1 (DE)
Title: Lorry hydraulic tailgate hoist - with dual pumps and electric motors for failsafe operation if one pump or motor fails (OE151076)
Inventor: WEBER WALTER ING
IPC: B60P1/44
Filed: 1976-07-09
Abstract: The hydraulically operated tailgate lift has a large vertical ram which raises the platform and a small ram by which the gate is swung from the vertical to the horizontal setting. For simple operation the rams are powered by individual hydraulic pumps driven by separate electric motors. This provides a quiet operation without having to run the lorry engine. For a simpler control, the vertical raising ram is driven by a large capacity pump and the tailgate pivot ram by a small ram, which allows the gate to swing smoothly. If either pump fails then manual changeover valves can be operated to raise and secure the tailgate, at a slower rate if need be. This allows the driver to move the vehicle to a repair centre.
Patent DE-2634171-A1 (DE)
Title: Supply and deflection circuit for TV receiver - prevents noise feedback by isolating HF circuit using filter
Inventor: FREUER HEINZ-GUENTER
IPC: H04N5/21
Filed: 1976-07-29
Abstract: The suppy and deflection circuit, for a television receiver, is designed to prevent RF interference being fed back to the receiver's coaxial input. A filter network is used to isolate electrically the interface between the IF stages and the following circuits of the receiver. The filter network consists of a magnetically coupled IF filter directly before the video rectifying stage. The entire HF part of the receiver is electrically isolated from the rest of it so that relatively low frequency RF noise (from the deflection circuitry and supply circuit) cannot find its way to the input of the receiver.

Title: Used fuel element storage chamber with high lateral stability - made from two outer half-shells and divided internally into four chambers
Inventor: KRIEGER FRIEDRICH
IPC: G21C19/40
Filed: 1976-11-19
Abstract: A chamber for housing used fuel elements from a nuclear power plant comprises an outer shell which is square in plane and is fitted externally with shielding panels, pref. of sintered boron, each covered with an outer protective plate. The shell is made up of two identical half-shells, each comprising two adjacent sides of the whole shell and thus having the form of a right-angle in section. The complete shell also contains four identical, smaller half-shells, the corners of which are towards the centre, thus dividing the larger, outer shell into four equal compartments each for a fuel element. These smaller half-shells are also externally clad with shielding panels and are equally spaced from one another. Used to constitute a larger assembly of fuel element storage systems anchored at top and bottom in a support system designed for transmitting horizontal forces, e.g. arising from earth-quakes, into the bottom of the storage pond. Existing arrangements comprise relatively tall and slender shells, whereas the newer system results in broader shells which are more stable and structurally superior.

Title: Extreme house heat insulation - reduces wall, roof and window heat losses making central heating superfluous
IPC: E04F13/08
Filed: 1977-02-16
Abstract: An insulation process is to effect extreme reduction of all heat losses from a house, so as to make central heating plant or night storage heaters superfluous, with min. temperature gradient, and a single control stove sufficing for evenly distributed heating of the whole building. An insulating facade for this purpose can use thick hard foam panels (1) cemented to the wall, or held by sheet metal pieces (2) screwed to it, with a cladding of heavy panels (4) or flexible profiles fixed to these. A similar system can be used for roofing. Windows can have an auxiliary pane in a rubber profile, fitted from outside so that the latter fits against the blind frame and seals the gap. This is economically installed anywhere where there is no central heating, or where renovation of old buildings involves facade renewal. In new buildings it can be used in conjunction with solar heating.
