Title: Decorative or transparent protective overlay - designed for chipboard to prevent surface flaws
Inventor: MUNK EDGAR
IPC: B44F1/00
Filed: 1974-01-31
Abstract: Chipboard overlay, e.g. transparent plastics film, has added to it a luminous material which becomes luminous under a frequency which is contained little, or not at all, in the spectrum of daylight or ordinary artificial light.

Title: LF analog power amplifier - has inverse control and combination of three amplifiers, two constant sources and multivibrator
Inventor: HOPPE KURT PETER
IPC: H03F3/217
Filed: 1974-03-22
Abstract: The first differential amplifier (adder, inverter) forms a negative sum of an input signal voltage and a bias voltage; its output is connected to the input of a first constant current source and of a second differential amplifier (inverter). The positive sum of the input signal voltage and bias voltage is delivered by the second differential amplifier output and controls directly the second constant current source so that the two constant current sources are controlled by opposite polarities, realising the inverse control. The outputs of the two constant current sources are connected to the two inputs of an astable multivibrator, whose two outputs deliver two rectangular voltages whose arithmetic mean value corresponds to the content of the input signal. The multivibrator is followed by a power switching amplifier for the rectangular voltages.

Title: Circular cross-section heat exchanger - having series of concentric annular straight tubes bundles with annular collectors and distributors
Inventor: ECKER HANS
IPC: F28D7/16
Filed: 1974-08-01
Abstract: Circular cross section ht. exchanger contains a number of straight parallel tubes inside a shell, the tubes being joined to collectors at each end. They are arranged as a series of concentric annular bundles with the collectors being concentric annular chambers arranged around the central axis of the shell.

The collectors can have a rectangular, circular or semi-circular profile. The exchanger is of particular use in the nuclear power generation field, as a stream raising boiler. It allows the max. possible amount of tubes to be included in the shell yet giving low press. drops with good heat transfer.
