Title: Cooking ring protection for electric cooker - cooking rings are covered with a thin aluminium sheet
Inventor: KALKOWSKI KURT ULRICH
IPC: F24C15/14
Filed: 1974-11-25
Abstract: In order to protect the heating rings on the top of a domestic electric cooker, pieces are severed from a roll of thin aluminium or aluminium alloy sheet, pressed onto the top of the cooker using hand pressure, so as to crease the sheet to cause it to remain in position, so that one protects the top during cooking or boiling. The sheet may be marked so as to indicate the size to ensure that sufficient margin is left to protect the edges of the heating rings. The roll may be marked with a line down each edge, using e.g. NH4 Mn P2 O7 which will change colour at about 400 deg.C to indicate the temperature. A square of the sheet would be about 55cm along its sides.

Title: Machine-readable coded circuit board - has bar-coded optically-readable paint strip along board edge
Inventor: KOBSA BERNHARD
IPC: H05K13/08
Filed: 1975-03-27
Abstract: The machine-readable coded circuit board has a strip of coding bars along its edge suitable for optical reading by a machine. The coding bars are located on the same side of the board as the components and can be produced in several ways: by screen printing laser to burn-off coding gaps in continuous painted lineby painting the bars separately of a continuous painted linecoloured paints. The advantage of using these thin lines of coding bars along the edge of the board lies in not affecting the board's operation and in being simply altered.
Patent DE-2530100-A1 (DE)
Title: Cooling for rotating magnet with superconducting windings - using convection generated in closed cooling channels forming thermosiphon
Inventor: HOFMANN ALBERT DIPL PHYS DR
IPC: H02K9/20
Filed: 1975-07-05
Abstract: The coolant flows through the cooling channels to absorb heat from the windings and deliver it to a recooling plant. A convection flow is generated in each of the closed cooling channels. This forms a thermosiphon by heat losses continuously generated in operation owing to radiation through thermal insulation, and to thermal conduction through the driving shaft. Coolant circulation is increased by centrifugal forces applied to it. Coolant in each of the channels is under supercritical pressure, and convection heat is delivered to a coolant bath boiling at normal pressure. It is integral with the rotating magnets, and liquid coolant is fed to it at normal pressure, while evaporated coolant is removed from it.

Title: Speed regulator for electronic fuel injector systems - has sum of engine speed and air intake volume dependent signals to depress fuel injection commands
Inventor: DREWS ULRICH DIPL ING
IPC: F02D41/02
Filed: 1975-10-21

Title: Rotary piston pump for liquids - has rotor with relieved tooth tips for reducing excessive contact with chamber
Inventor: SEIDEL FRIEDRICH DIPL ING
IPC: F04C2/10
Filed: 1975-11-22
Abstract: The rotary piston pump is used especially for pumping of liquids. The pump rotor has a number of teeth, separated by concave spaces which rotates within a chamber with conjugate profile. The chamber has a number of radial slots which are connected by convex sections. The number of pitches of chamber features is greater than the number of pitches in the rotor. No sealing profiles or springs are used and the efficient sealing increases the volumetric efficiency of the pump. The tooth tip profile of the rotor has side regions 28, 29, 30 which are relieved. These regions do not contact internal teeth of the chamber and hence the number of simultaneous contact points between rotor and chamber is smaller than the number of teeth in the chamber.

Title: Gluing foil or veneer to wooden panel edge - using polyvinyl acetate glue heated to softening temp. after thinner evaporation
Inventor: RIESMEIER WILHELM
IPC: B27D5/00
Filed: 1976-07-02
Abstract: The process for glueing continuously forwarded foil sheets or veneers onto wooden panel-shaped workpieces, with prehating of workpiece surfaces, involves simultaneous application of glue with thinner to the workpiece and to the foil or veneer, bringing thw coated and heated surface together and pressing the foil or veneer onto the workpiece. The glue is a polyvinyl-acetate, heated to softening temp.
