Title: Embossing side of open ended metal tubes etc. - using one roller pressing can against another roller with attached mandrel
Inventor: BRODERICK FRANK W
IPC: B44B5/00
Filed: 1974-01-31
Abstract: The embossing machine has a tubular mandrel mounted in bearings and driven by a gear. The mandrel is rigidly attached to the embossing roller by a key. A disc runs on a bearing on the mandrel. A shaft driven by the gear passes through the mandrel and carries a disc at its outer end. The two discs have a diameter slightly less than the bore of the tube which is to be embossed. When the machine is driven by the shaft through the gears, the tube is embossed by the upper roller pressing it against the surface of the embossing roller.

Title: Combustion engine with interior cooling - water is injected during combustion process
Inventor: BIESTERFELDT HARALD
IPC: F02B77/11
Filed: 1974-02-01
Abstract: The engine block is heat insulated so that the energy produced by combustion can not escape, the exhaust pipe is wound round the block underneath the insulation. A heat sensor in the combustion chamber regulates relays which maintain a constant inner temperature by increasing the water injection as the combustion chamber temperature increases and increasing the fuel quantity injection as the temperature decreases. Ignition is by damp insensitive high tension spark. The exhaust gases are fed through a condenser and filter so that the water content can be reused. The water pipes are insulated against frost and the container is similarly insulated.

Title: Automatic feeder for poultry or pigeons - door is pivoted open by weight of bird on pivotal footboard
Inventor: KLENK ADAM
IPC: A01K39/00
Filed: 1974-02-08
Abstract: The automatic feeder allows birds to feed at any time and vermin cannot reach the feed. The body (1) has a floor sloping downwards to the front (6, 9) which has openings for a bird's head and neck. An inside partition (4', 57, 58) and lid (11) gives storage space for the food, available through a hole in the partition base (57, 58). A door (30) hinged at the top, normally closes the front openings, but opens when a bird steps onto a hinged footboard (22). Its weight depresses this footboard and a connecting link (53, 55, 56) pushes the door upwards. The bird can then feed. The door closes when the bird steps off.

Title: Tile sorting and stacking system - capable of sorting out tiles with varying colour shades
Inventor: PLANZ EGON JOHN DR ING
IPC: B07C7/00
Filed: 1974-03-09
Abstract: Sorting and stacking method for tiles which are moved past a sorting position on a band consisting of several parallel rows of tiles. These tiles having a colour shade varying from the norm are moved from the band and are placed behind each other on to a cord moving next to the band and moving similarly. Finally the remaining tiles as well as the removed tiles are separately stacked by machine. Two sortings of tiles may take place simultaneously and the tiles are arranged in straight rows both along the length and across the conveyor band. Before the band is formed any tiles which are damaged or have faults are sorted out.
Patent DE-2412089-A1 (DE)
Title: Waste disposal unit swivelling door - activating chute-sealing flap with differential rod for locking and opening
Inventor: SCHUDERA WOLFGANG
IPC: E04F17/12
Filed: 1974-03-13
Abstract: The purpose is to effect coverage of the disposal chute when the access door is partially as well as fully open to prevent escape of smell dust and noise. The door opeates a sealing-flap, which interrupts connection to the shaft, and is linked to it by a differential rod. This transforms a narrow swing of the door into a wide swing of the flap. When the latter is closed, a locking position of individual components of the rod assembly is established, not affected by further opening of the door; when the door is swung back these components are returned from the locking position to their original setting.

On the Cu-side, there are fine structures applied by means of photomasks and photographic techniques. Sn is deposited on the fine structures by galvanic process. The photo-lacquer is removed on the Cu-side; the Cu is etched away in controlled manner, and the photo-lacquer is removed on the underside (of the Cu). Specifically, the plastics tape is perforated according to (German Standard) DIN 15 851, sheet 2, form A.
Patent DE-2418327-A1 (DE)
Title: Laser beam guidance system for foggy conditions - is effective for vehicles ships or aircraft using fixed sources and reflectors
Inventor: BRITSCH WALTER
IPC: E01F9/20
Filed: 1974-04-16
Abstract: The coherent light of laser beams, which is emitted in different colours, is used for the guidance system. The condensates of fog causes the light beams to illuminate. Thus, a lateral guidance and limitation are achieved, which represent a practical and secure aid protecting live and limb. A limited number of light sources provide a wide guidance distance. By means of further focussing and diversion at curves and at crossing points of the terrain, the fixing point and similar reference points can be marked, also the direction is indicated. This applies also to the movement of ships and to air traffic.

Title: V. engine exhaust and inlet valve adjustment system - has single eccentric shaft for both inlet and exhaust
Inventor: ALTMANN WERNER
IPC: F02F7/00
Filed: 1974-06-15
Abstract: The design is an improvement to 2363891 and permits the use of a single eccentre shaft to actuate both inlet and exhaust valves. The valve operating shaft (2) has a crank (3) which when rotated lifts and lowers a connected bar (4). The bar has a roller (6) on one side of its free end and a cam face (5) on the opposite. The cam face presses against a rocker arm (7) pivoting on a shaft (17) to open and close the exhaust or inlet valve in the usual way. The connected rod roller presses against a wedge shaped piston (9) which is located in a bore in the valve cover housing and secured by a spring loaded set screw (15). The wedge shaped piston is able to slide in its boring corresponding to the position of the eccentre shaft fitted above the piston.

Title: Remote switching control for telephone equipment - responds only to call (s) within given time period
Inventor: LAUERER FRIEDRICH DIPL ING
IPC: H04M11/00
Filed: 1974-10-21
Abstract: The remote switching control, for telephone equipment, has circuitry at the receiver to ensure that the switching process or signalling of the switch condition only occurs if the call falls within a narrow time space. This time space can be adjusted in length and starting point. Alternatively, circuits can be included that only release the switching process or switch condition if two or more calls follow one another in a given time space. The receiver also has circuits to switch off a switched-on piece of equipment after a given time has elapsed. The time switch (3) can be adjusted so that it automatically closes the contact during a certain period.

Title: Windscreen cleaning mechanism with air currents - keeps rain etc away from surface by air fed by compressor
Inventor: NOCKE GEB WEFING WALTRAUD
IPC: B60S1/58
Filed: 1975-03-18
Abstract: The windscreen sleaning mechanism comprises a compressor which can be incorporated in and driven by the car engine so that a dense fast-flowing air current (11) can be artificially produced in front of the surface of the windscreen and then guided up away and over the top so that any rain and dirty spray is kept away from the windscreen. This is because the artificially produced energy of the air current is greater than that of the particles forming the dirt and also water or other dirt-removing additives can be mixed with the air current which can also be heated. The force of the air current can be controlled in dependence on the speed of the car. The mechanism can also be used for ships, aircraft etc. This system ensures the entire surface area is kept clear without windscreen wipers.
