Title: Pocket calculator with solar cell power pack - has control pulse generator producing pulse only for duration of calculation to save power
Inventor: KRAUSE GERHARD
IPC: G06F15/02
Filed: 1976-08-05
Abstract: The energy consumption of pocket calculators with solar energy cells supplies is minimised by only supplying the circuits with energy during the short interval that a computation is occuring A control pulse generator (S) produces a short duration impulse (0.15) when an arithmetic operation is initiated. The signal is used to close gates (S1, S3) to transfer information from input (E) to the arithmetic circuits (R) and to output to the drive display stages (S3). A main switch (S2) couples in the solar cells and allows the stored energy in a capacitor (C) to be made available for circuit use. An additional facility allows a measured external parameter to be entered and amplified, followed by conversion and display.

Title: Eddy current materials testing - using multiple frequencies and multiplexers controlled by timing pulse generator
Inventor: BECKER RAINER
IPC: G01N27/90
Filed: 1977-09-05
Abstract: In a non-destructive test of materials by the eddy current method, several frequencies in the range 100-400kHz are applied to a test coil to produce a primary magnetic field. This generates eddy currents in the workpiece with an associated secondary field. A measuring coil determines the in-phase and reactive components of the impedance. A timing pulse generator feeds the test frequencies fast enough in the coil to blur the frequencies of each cycle no more than is required for the local resolving power. This reduces the amt. of electronic instrumentation required and provides a local allocation of the signals of adequate accuracy.

Title: Solar radiation heat exchanger - consists of low cost panel with water in circulation channels covered to reduce ratio of emitted to incident radiation
Inventor: MCALISTER ROY EDWARD
IPC: F24S10/50
Filed: 1977-10-14
Abstract: A solar heat exchanger consists of a panel, one surface of which receives solar energy. That surface has parallel V shaped grooves which extend over the length of the panel. Three sheets of plastic are laid over one another on the surface and form outer, intermediate and inner spaces, extending over the length of the grooves, and bounded by the walls of the grooves and the sections of the sheets extending over them. The outer and intermediate spaces contain air. The inner spaces, of triangular section, constitute channels through which water circulates, and which connect with gutters at the ends of the panel. Pipes connected to the gutters feed water and take it away. The water receives radiations after they have passed through the sections of sheets and the outer and intermediate spaces. The collector is simple to construct and can be readily dispatched, stored and installed at low cost, whereas the costs of existing collectors prohibit their wide use. It collects incident light of all wavelengths and emits only a small quantity of radiation. The temp. can be controlled preventing damage if fluid circulation is interrupted. Conversion of incident energy is considerably greater than with existing panels.

Title: Wet grinding aluminium - to form a powder with addn. of boric acid or a fatty substance
Inventor: KIND WERNER DIPL ING
IPC: B22F9/04
Filed: 1977-12-08
Abstract: Al is ground to powder by adding >=20 wt. % water to the aggregate and grinding at 10 degrees C or adding =15 wt. % boric acid and/or 16 wt. % fatty substance e.g. wax or fatty acid and drying is carried out by centrifuging the wet ground material or by pressing. The vapour pressure is then decreased to normal value at room temp. and the material is agitated continuously. Alternatively the material is dried in stages by raising the temp. >=90 degrees C in a protective gas atm. Grinding a mixt. of Al and water at 10 degrees C avoids a reaction between water and Al. with increasing fineness of the powder the temp. is increased. Process does not use combustible liquids and avoids a coating of stearic acid on the particles which is undesirable when the powder is sintered. Used for sintering purposes, as colouring agent, or in fireworks and concrete.
