Title: Electronic determination of maximal and minimal values - of parameter during defined sequence of events uses analogue to digital converter
Inventor: BORNHORST HUBERT DIPL-ING
IPC: G01B7/312
Filed: 1973-07-20
Abstract: An electronic logical network ascertains the maximal and minimal figures for out-of-true measurement of a shaft. The test piece si rotat ed between two accurately placed nodes, the displacement of the surface being measured by a suitable transducer. An analogue digital converter periodically converts this to a binary coded decimal format, and this is compared with the contents of two registers, one for the maximal and the other for the minimal readings. The sequence is started by entering zero in the maximal register and the maximum possible reading in the minimal register. The result of these comparisons is used to update these registers so that at the end of a shaft rotation they contain the maximal and minimal values.

Title: Laser fingerprint identifier - has space filters in fourier transformation plane, to produce extreme intensity values
Inventor: MCMAHON DONALD HOWLAND
IPC: A61B5/1172
Filed: 1973-10-19
Abstract: Laser identifier for finger prints has the spatially modulated beam resulting from illumination of the fingerprint, focused to produce a spatial frequency pattern in a Fourier transformation plane of the processor. The light from this pattern is received to give an image of the fingerprint in an image plane, in which light detectors are located at discrete positions to respond to respective finite scanning regions of the fingerprint where the lines are to be investigated. Space filters in the Fourier transformation plane scan the spatial frequency pattern and produce an extreme value at the respective detectors successively corresp. to the alignment of the lines in the associated scanning regions. The time interval is determined between a previously selected time reference and the instant of appearance of an extreme value of the light intensity at each light detector.

Title: Deflection pulse generator for camera or picture tubes - has timing stage delivering an output pulse for each synchronisation pulse
Inventor: HEISTER HEINZ
IPC: H04N5/12
Filed: 1974-01-31
Abstract: Theoutput pulse width is sufficient for a deflection pulse generation, and the pulse is applied to a first input of an OR circuitry, whose other input is connected to an auxiliary oscillator, blocked by the timing stage output pulses. The timing stage controls a monostable flip-flop whose time constant is somewhat greater than the synchronisation pulse period. It blocks the auxiliary oscillator which delivers an output pulse at the flip-flop output pulse rear flank. The timing stage, a preceding amplitude filter, the auxiliary oscillator and the OR circuit, and a vertical saw-tooth voltage generator are produced as an integrated assembly.

Title: Skid protection brake pressure regulator - HAS TWO EXPANSION CHAMBERS TO GIVE A PROGRESSIVE BRAKE PRESSURE REDUCTION
Inventor: BLANZ ROLAND
IPC: B60T8/74
Filed: 1974-03-07
Abstract: The regulator housing contains a brake valve controlled by a quick release membrane and a double valve unit using the drawn in edge of the housing as an inlet valve seat for the brake control pressure and working together with a regulator piston fitted co-axially to itself to form an outlet valve. A magnetic valve excited by impulses obtained from sensors fitted to the road wheels causes air to act upon the large surface of the regulator piston, whereby the piston is moved against its first movement until the inlet is closed and the outlet opened. Whilst the outlet is opening a connecting channel is opened and air is able to flow to an expansion chamber. The quick-release valve reduces the pressure on the brake valve at the same time.
