Title: Photo-camera with adjustable image scan speed admitting light strips - has screen with slit synchronised to shutter vanes focussing beam through slit on to film
Inventor: BERG JOHANNES CORNELIS MARIA V
IPC: G03B9/28
Filed: 1974-01-25
Abstract: Photo camera with an adjustable speed of image scan and with the shutter admitting only a strip-shaped light beam at a given rate. This allows pictures to be taken into the sun or other light source without the risk of over-exposure. The camera has a screen with a longitudinal slit, fitted between the space for the sensitive film and the shutter. The screen is operated by a mechanism, synchronising its movement with that of the shutter in such a manner that an incident light beam will always hit the screen at the slit. The shutter consists of parallel rotatable vanes (1) directing the light strips (3) onto the lens (4). The lens focusses the beam through the slit (8) of the adjustable screen (7) onto the film (5). The screen (7) moves in unison with the shutter vanes.

Patent DE-2422028-A1 (DE)
Inventor: REITBOECK HERIBERT J
IPC: G10L25/15
Filed: 1974-05-07
Abstract: The use of electronically tunable filters permit an efficient extraction of characteristic speech features, such as pitch frequency and the position of spectral peaks, called formants, that are present in vowels and voiced consonants. A pair of electronically tunable active filters each controlled for CF and Q, are utilized to "lock in" on a particular formant and to follow its inflections. The control voltage supplied to the active filters directly corresponds to the formant position and gives an inexpensive and simple technique for the characterization of voiced phonemes.

Title: Recording, coordination and reprodn. according to distances covered - for direction-finding in trips, round tours and inspections
Inventor: COLLINS GEB JAECKEL LIESELOTTE
IPC: G06F19/00
Filed: 1974-05-31
Abstract: For the purpose of reproduction, according to the length of the distance covered, of part distance information or junction point information, a pulse generator actuated by kilometer counting gear is used to emit pulses at intervals of a part distance unit which are counted in reverse by an electronic part-distance unit counter. This counter is preset to the number of part distance units covered up to the next information point or junction point, set at zero just before reaching such a point, triggers a signal tone warning the operator, starts an instruction counter and switches on the forward wind of the tape cassette.

The hinge point for the lever, the slot and the hinge point of the two parts are in line with one another, so that when the lever is moved over a small angle, the protrusion on the lever will engage with the side of the slot and move the second part relative to the first one. The end of the lever is pointed and is in line with graduated markings on one of the parts so that the amount of adjustment can be judged.

Title: Digital counting system of micro-biological colonies - has TV camera evaluator converter, shift register counter and monitor
Inventor: PERRY RUSSELL C
IPC: G06M11/02
Filed: 1974-09-11
Abstract: The specimen containing the colonies is held by a support and a TV camera is trained on the support or the specimen. The output video signals are passed to an evaluator and converted to horizontal counting lines, each line containing a series of signals and representing a colony. A converter produces pulses with a width which corresponds to the measurement of the colony along a line. The shift register produces a single output signal for each colony and passes it to the counter for evaluation. A control circuit represents the video output from the TV camera and passes it to the monitor.

Title: Frequency division multiplex system with N channels - uses method for marking nominal load of unit tested by white noise
Inventor: HEIDENREICH KARL-HEINZ
IPC: H04J1/16
Filed: 1974-10-19
Abstract: White noise with a bandwidth B corresponding to that of the multiplex signal is produced. It has an adjustable level and a narrow gap in the noise spectrum. Channel noise in the tested system and alternatively the part of the white noise outside the gap, or with the gap filled with noise, falling in the tested unit selective band b is measured at the unit output; the quotient B:b is a measure for the test load, whose nominal value is an agreed function of the channel number. A "test load" test can be used, in which the receiver sensitivity can be adjusted in steps which take into consideration both the channel number and the ratio B:b the receiver displays for all systems the same value when the load at the tested unit output is just equal to the nominal load.

Title: Removing volatile components from molten polyamides - by subjecting polyamide to turbulent treatment with gas stream at subatmospheric pressure
Inventor: FREUND PETER DIPL ING DR
IPC: C08G69/46
Filed: 1974-12-31
Abstract: Volatile components are removed from molten polyamides, e.g. nylon 6, before melt spinning by (a) subjecting the molten polyamide to turbulent treatment with a gaseous medium at a sub-atmospheric pressure, (b) continuously withdrawing and recycling a part of the molten polyamide, and (c) imparting the recycled part with the gaseous medium so that an intimate mixt. is formed. The molten polyamide is exposed to very intensive contact/mixing with the gaseous medium, so that monomers/oligomers are efficiently removed. A relatively small amount of gaseous medium is used.

Title: Linear motor for operating power press guard - is controlled by foot switch and safety contact on guard
Inventor: SCHMIDT THEODOR
IPC: F16P3/02
Filed: 1975-05-20
Abstract: The operator guard (2) of a power press (1) has a vertically movable screen (3) which covers the danger area of the press. A vertical bar (4) attached to one edge of the screen (3) is part of a linear motor (5) which is provided to move the guard up and down. A permanent magnet (9) retains the guard in the open position when the linear motor is switched off. When a foot operated switch is actuated (7), the linear motor brings the guard down which in turn starts the working stroke of the press. A contact rail (10) on the lower edge of the guard cancels the foot switch signal if the operators hands are in the danger zone of the press.

Title: Treating supplementary water for swimming pools - by anion exchange with basic resin in chloride form and introduction of carbon dioxide
Inventor: KESSLER DIETER P
IPC: B01J41/05
Filed: 1975-05-23
Abstract: Supplementary water for swimming pools (in-or outdoor, public or private) is contacted with a very strongly basic anion exchange resin in the chloride form (regenerated with NaCl soln.). Subsequently, a small quantity of CO2 (2-24 mg. CO2/l.) is introduced into the pool in the gas form or as dry ice. The total mineral content of the supplementary water is reduced to 0.4-1.0 equiv./l., and that of the water in the pool is kept within the range 1.3-1.4 equiv./l. The supplementation can be carried out continuously or discontinuously. Sulphate, nitrate, carbonate and bicarbonate ions are removed from water and replaced by chloride ions. Thus most of the calcium and magnesium is in the form of the readily soluble chlorides. The remaining small quantities of CaHCO3 and MgCO3 do not form encrustations. The total mineral content in the pool is kept at a constant admissible level. The pH value is kept withn the desired range of 7.2-7.6.
Patent DE-2530503-A1 (DE)
Title: Heat pump driven directly by engine - uses heat engine rejected heat for maintaining required temperature
Inventor: HEIN KARL DIPL ING
IPC: F25B30/06
Filed: 1975-07-09
Abstract: The heat pump is directly driven by an i.c. engine which eliminates electrical transmission losses and ensures that it can be driven by a stored energy. The rejected heat from the engine is almost fully integrated into the input circuit of the heat pump and it ensures very high primary energy utilisation efficiency. The heat pumps are designed for optimum efficiency and the temperature level of the heat carrier is raised by the heat losses of the internal combustion engine. The combined plant can also have integral electric motor or generator for generating electric current. In this case the heat pumps can be driven optionally by the engine or by the electric motor.
