Title: Optical system in instrument for coin inspection - reproduces details of angular distributions of relief inclinations of reference coin as beam deflections
Inventor: ANTES GREGOR DIPL PHYS
IPC: G07D5/00
Filed: 1977-04-21
Abstract: The optical coin inspection instrument consits of a light source which illuminates a test piece, a receiver and an optical element. The optical element is placed between the light source, the test piece and the receiver. The instrument contains details of the relief in one selected zone of the reference coin. The details of the local distribution of the angles of inclination of the relief of the reference coin (m) are reproduced in the form of beam deflectors in the optical element. The beams reflected by the test piece (M') will converge mainly to the detector surface of the receiver (Ple), when the local distribution of the angles of inclination of the relief of the test piece correspond to those of the reference coin.

Title: Pressure seal openings for bulk carrier tanks - include covers in sliding supports to reduce working height (NL 28.12.77)
IPC: B60P3/22
Filed: 1977-06-21
Abstract: The filling ports of the bulk carrier are sited on top of the sealed tanks and comprise flat plates which slide horizontally in guide rails along the top of the tanks.

Title: Monitoring circuit for incandescent lamps on vehicle - measures volts across resistor in series with lamp and operates optical indicator
IPC: H05B39/10
Filed: 1977-09-12
Abstract: The monitoring circuit, for monitoring incandescent lamps in motor vehicles, measures the voltage drop across a resistor in series with each lamp using an operational amplifier. The amplifier output drives an optical indicator that shows when the lamp has failed or when the voltage across the series resistor is too small. Each lamp or pair of lamps has its own operational amplifier and indicator. The switch (S) that turns on any lamp or pair of parallel lamps (L1, L2) is connected between the voltage supply and e.g. the positive rail of the monitoring circuit so that the latter is only on when the lamps are on.

Title: Continuous double coating of cereal particles - with fat followed by dilute syrup
Inventor: COLE JUN KEITH MERLE
IPC: A23P20/10
Filed: 1977-11-22
Abstract: A mixt. of edible particle of differing size, shape and density are coated first with an oleoagineous spray coating and subsequently with a dil sweet syrup.

Patent DE-2756357-A1 (DE)
Title: Sealing arrangements for a rotating heat exchanger - ensuring maximum efficiency and minimum leakage with multiple adjusters
Inventor: STOCKMANN RICHARD FRANKLIN
IPC: F28D19/04
Filed: 1977-12-17
Abstract: Regenerative rotating heat exchanger with a rotor formed of a heat-absorbent material mounted around a central shaft. The rotor is surrounded by a cylindrical body, an annular space being left between the rotor and the body. The body contains, at the opposite ends of the rotor, plates provided with openings to direct a fluid to be heated and a heating fluid across the rotor. The rotor is turned in order that the heat absorbent material may be displaced progressively from the hot to the cold fluid and back again. The cylinder is fitted at each end of the rotor with adjustable sealing devices which give a fine adjustment to allow for optional efficiency in performance. The arrangement allows the relationship of the joints to each other to be maintained permanently in the positions giving maximum leak-tightness. They avoid problems due to the erosion of parts by the particles which may be carried in the gases passing through the exchanger.
