Title: AF signal sequence generator - has code signals representing data positions and converted into AF frequency signals for transmission
Inventor: DALLMANN HORST
IPC: H04W88/02
Filed: 1975-02-08
Abstract: The AF signal sequence generator has characters symbolising each data position and the characters themselves are resented by discrete audio frequencies. (If two consecutive characters are the same then a special repetition frequency is used for the second). Each character has its own discrete code signal constructed from a binary code. This code signal is compared (4) with a code signal, retained by an auxiliary memory (o), for the previous data position. The code signal is only then converted into the corresponding audio frequency if the comparator detects that the two code signals are different.

Title: Open end, spinning turbine with contour diminishing friction - and finish of guiding wall progressively improving towards fibre collector
Inventor: STAHLECKER FRITZ
IPC: D01H4/10
Filed: 1975-03-11
Abstract: An open-end spinning turbine has, between its inside bottom surface and its inwardly inclined walls, a fibre collecting zone, the surface of this zone at least being processed by shot-blasting with very fine grain material so as to impart to it a lesser coefft. of friction than that of the fibre-guiding walls of the turbine. The device provides a surface which agitates the boundary layer of air moving past, without holding the fibres, so that frictionless sliding and stretching out of the fibres is ensured. A side effect consists of the rejection by the special surface, of deposits of dirt.

Title: Fingerprint or pattern recognition system - uses incoherent light source with absorbing element alignment for error elimination incorporated in rotating optical grid
Inventor: MCMAHON DONALD HOWLAND
IPC: A61B5/1172
Filed: 1975-09-17
Abstract: A pattern recognition device, in partic. an incoherent light fingerprint identification system, avoids the use of expensive optical elements for alignment error elimination. An arrangement of photo-detectors, each corresp. to a sampling region of the fingerprint, receives an image of the print filtered by a rotating optical grid. An incoherent light source and retroreflecting prism are arranged with the grid so that maximum detector illumination occurs when print lines coincide with grid lines. Detected optical signals are converted into characteristic electrical signals. The grid bears a mounting (26) for a regular arrangement of elongated alternately reflecting (51) and transparent (52) elements, with absorbing elements (50) positioned between them to preclude error-inducing full alignment.
