Patent DE-2340443-A1 (DE)
Title: Polyurethanes dyed with fast metal-complexed colourants - integrated into polyurethane mol during polymn.
Inventor: MAEDA SHIGEO
IPC: C08G18/38
Filed: 1973-08-09
Abstract: Coloured polyurethanes are mfd. by reacting metal-complexed dyestuffs with a polyisocyanate cpd and a polyhydroxy cpd. to form solns, suspensions, aq. dispersions or elastomers. The metal-complexed dyestuffs must contain one amino- or hydroxy-gp. with active hydrogen; they are either copper phthalocyanins or the complex salts of chromium or cobalt with monoazo dyestuffs, all with appropriate substits to provide the amino- or hydroxy-gp required for reaction with isocyanate. The polyisocyanate is a di- or tri-isocyanate or a prepolymer formed by reaction with a polyether or a polyalcohol such that residual isocyanate gps remain active. The polyhydroxy cpds are polyglycols or polyesters or reaction prods of these with isocyanates and contain residual hydroxy gps. Reaction is pref. carried out in solvents inert towards isocyanates, e.g. mixed tetrahydrofuran and dimethylformamide. The coloured polyurethanes so formed can be recovered in soln, dispersion or as solid elastomers. The colourant is chemically bound into the polyurethane molecule during formation of the polyurethane, instead of being mechanically dispersed or dissolved therein. All conventional uses of polyurethanes benefit by having the colourant inextricably molecularly bound. Colour is accordingly water-and oil-resistant, light fast and non-bleeding.

Title: Bistable magneto-optical light-dark switch - contg. polariser, iron borate monocrystal rotator and analyser
Inventor: FELDTKELLER ERNST DR
IPC: G02F1/00
Filed: 1973-09-13
Abstract: Bistable magneto-optical light-dark switch, is which the light is passed through a polariser, a Faraday rotator and an analyser; the polarisation planes of the polariser and the analyser forming an angle of 45 degrees, and the rotator turning the polarisation plane by +45 degrees or -45 degrees when magnetised to saturation in the presence direction or oppositely (this charge remains even after the removal of the external magnetic field) is improved in that the Faraday rotator consists of at least one magnetic monocrystal plate (pref. consisting of Fe3BO6) whose magnetic preference axis is perpendicular to the main plate surfaces, and which remains in the magnetic monodomain state even after the removal of the external magnetic field after saturation along the magnetic preference axis. The Faraday rotator can be produced in relatively simple manner. Fe3BO6 preserves at room temp. the magnetic equilibrium of the monodomain state irrespective of the magnetic prehistory.

Title: Monitoring surface treatment processes - change in test-piece wt. converted to electric signal and used to operate dosers
Inventor: LIEBER HANS-WILHELM PROF DR IN
IPC: C23F1/02
Filed: 1974-03-08
Abstract: A process for monitoring the surface treatment of workpieces in electrolytic or chemical baths, using a weighing device and a test-piece (I) of known surface area. The novelty is that by the deposition onto, or the dissolving of piece (I) the alteration in wt. is converted into an electric signal which indicates either the thickness of the deposit or the material removed; the speed of the wt. alteration is used to indicate the speed of deposition or dissolution, and is also integrated w.r.t. time and multiplied by a factor corresponding to the surface area of the work being treated so a value is obtd. which indicates the amt. of substances converted in the bath. The data obtd. is pref used for controlling the presences and/or a dosing unit which feeds replenishment materials into the bath. Automatic monitoring of e.g. pickling, etching, electroplating, anodising and electropolishing, or coating by chemical redn. e.g. of gold.

Patent DE-2418208-A1 (DE)
Title: Curtain hook arrangement for pleated curtains - has expanding support elements to accurately match curtain widths to curtain tracks
Inventor: HOLZLEHNER MARTIN
IPC: A47H15/04
Filed: 1974-04-13
Abstract: Support elements are in the form of two hinged bars which engage at the base of the pleats and longitudinally displace the curtain along the rail. The mutual spacing between the support bars which are associated with one pleat can be increased in the longitudinal direction of the rail whilst still maintaining the actual pleat and thus where there are two or more pleats forming a pinch pleat then the distance between the support bars having the largest mutual spacing can be increased to a limited extent. Thus where a pinch pleat of three folds on the outside is hung up by four loops on the reverse side the distance from the first loop to the fourth loop can be increased when the curtain is drawn by a minimum up to a certain distance whilst the pinch pleat still remains.
Patent DE-2422516-A1 (DE)
Title: Individual manipulation of speech pauses in language laboratory tapes - involves stopping of instructor's recorder during students repetition
Inventor: RICKEN HEINZ GUENTER
IPC: G09B5/10
Filed: 1974-05-09
Abstract: The equipment provide a means for a language laboratory instructor to arrange for his tape player to stop the tape run for a pre-arranged interval of time, during which students can repeat into their machines the sounds rehearsed by the instructor. From the sound frequency signal voltage of the speech flow an impulse is generated whenever the signal voltage is absent for a certain period of time in an integral section. The output of this impulse from the generator stops the instructor's tape recorder through an electronic, electromechanical or electro-magnetic switch which emits an electric impulse. A set of keys permits adjustment of the time during which the instructor's tape drive is stopped.

Title: Beer dispenser flow control to reduce froth - main tap supplies swinging arm with set of taps
Inventor: BEYERSDORFFER MARTIN
IPC: B67D3/04
Filed: 1974-06-07
Abstract: A beer dispensing system for a barrel (4) located in e.g. a cellar and forced under pressure through a supply line (5) to a serving position, has this line terminating at a main tap (6) from which extends a pipe (8) of a larger diameter, with branches extending downwards, each with a dispensing tap (9) for a row of glasses (11). This extension pipe can be swung up and down so that after the glasses have been lined up, and the dispensing taps turned on, the main tap can then be turned on, and the flow into the glasses then finally controlled by the dispensing taps to prevent too much froth being formed. The extension pipe slopes down from the main tap.

Title: Frame synchronisation signal clamping cct. - clamps bottom to fixed reference value using capacitor and diode
Inventor: ZSCHUNKE WILLMUT DR ING
IPC: H04N5/16
Filed: 1974-07-11
Abstract: The clamping circuit has a capacitor in the signal path and a diode controlled by a clamping potential and switched by a voltage comparator controlled by the synchronisation pulses and the clamping potential. The voltage comparator consists of a differential amplifier whose non-inverting input is connected to the signal path behind the capacitor, inverting input to the clamping potential and output to the diode. So soon as the input voltage of the differential amplifier (A), arising from the difference between the potentials of the video signal and the clamping (U), becomes positive a voltage of e.g. 3V. appears at the output. The latter is zero when the input potential is negative.
