Abstract: 1468856 Greying inhibitors in detergents CHEMISCHE WERKE HULS AG 14 June 1974 [15 June 1973] 26441/74 Heading C5D A washing or cleansing composition contains phosphate, a detergent component and, as a greying inhibitor, a mixture of (A) 30-95% by wt. based on the total mixture, of one or more carboxymethyl polyglycol ethers of the formula in which n is an integer from 9 to 20 and m is n/2À7 to n/1À7 and M denotes an alkali metal or NH 4  and (B) 5 to 70% by wt., based on the total mixture, of one or more alkyl polyglycol ethers of the formula wherein n and m have the above mentioned meaning. The alcohols used in the preparation of components (A) and (B) are fatty alcohols of C 9  to C 20  and especially C 12 -C 18 , which are straight or branched chain, saturated or unsaturated, synthetic or natural, e.g. coconut or tallow fatty alcohols. The polyglycol ethers contain 3 to 11 mols of ethylene oxide per mole of fatty alcohol. Preferred are C 12 -C 18  fatty alcohols condensed with 4À5 to 6 mols of ethylene oxide. The mixtures (A) and (B) are produced by reacting the polyglycol ethers with less than an equimolar amount of an alkali metal chloroacetate so that part of the alkyl polyglycol ether remains unconverted to carboxymethylether polyglycol ether. The greying inhibitor is used in quantities of 1 to 5% of the washing or cleansing composition and may be used in admixture with conventional greying inhibitors. A typical composition contains sodium C 10 -C 13  alkylbenzene sulphonate, C 16 - C 18  fatty alcohol + 25 mols ethylene oxide, soap, pentasodium triphosphate, tetrasodium diphosphate, sodium metasilicate, sodium perborate tetrahydrate, sodium sulphate, greying inhibitor and water.

Abstract: Powdered material is fed downwardly into the mixing chamber through a vertical feed pipe while liquid is fed into the chamber in the form of annular thin film descending along the inner wall surface of an inverted frusto-conical overflow structure arranged in a liquid tank in encircling relation to the powder feed pipe. Accommodated in the mixing chamber is an agitator disc having a large number of upwardly extending projections co-operable with stationary projections formed on the top wall of the chamber. An annular board is placed afloat on top of the liquid in the tank substantially coaxially with the tubular overflow structure to serve the purpose of preventing any adverse effect of surface disturbance upon the formation of thin liquid film.

Abstract: The type carrying disc has the type characters spaced irregularly along the disc periphery in dependence on their width, but the order in which these characters appear on the disc is independent of their width. Associated on the disc with each type character is an aperture that indicates the angular position of the corresponding type character. A photoelectric detector reads these apertures as the disc spins, and enables, in dependence on a coded signal, the disc to be stopped at the correct position for printing the desired character. In other embodiments, the aperture or other means indicates one or another printing characteristic, such as printing force or size of the printing step.

Abstract: An automatic control system wherein repetitive pulses, the frequency of which is responsive to a remote condition such as prime mover RPM, are converted to a D.C. voltage level which is then compared to a reference to produce an error signal. Three further signals are then produced, one proportional to the error signal, one proportional to its integral and the other proportional to its derivative. The three further signals are summed and amplified to the extent necessary and the resultant used to control an element which in turn controls the remote condition. Included is a fail safe circuit effective to cause the remote condition controlling element to shut off in the event incoming pulses are not present. Provision is made whereby the system may respond to the summed signals described above or an external signal which may be derived from a function generator or a limiting value established by an external condition. A particular application described for the system is its use as a governor system for prime movers such as internal combustion engines and steam turbines.

Abstract: An electro-mechanical pulse generator for producing electronic pulses to set or correct the readout of an electronic digital display. Two contact assemblies rotatable relative to one another cooperate to close at least two pairs of electric contact elements to produce at least two pulses. The pulses have a phase shift relative to one another which is dependent upon the direction of relative rotation of the contact assemblies and a frequency which is proportional to the speed of rotation. Control logic determines the phase shift of one pulse relative to another, i.e. lead or lag, and causes an UP-DOWN counter to produce an up-count or down-count accordingly.

Abstract: The present invention relates to a method of determining position, direction of movement and velocity of an object in motion. This is achieved in the invention by using an existing electromagnetic field from broadcast or TV transmissions. Signals are then received in at least two different points from such a transmitter, which signals arrive on the one hand directly and on the other hand after having been reflected in the object. Subsequently, starting from each receiving point, the difference in frequency between the reflected and direct radiation is formed continuously during the entire time sequence and the time derivative of the frequency around the minimum of the beat frequency is calculated. Finally, the conclusions are completed starting from this and knowledge of the position of the receiving points and also the direction from these to the transmitter. <IMAGE>
