Title: Improvements in or relating to process of washing clothes
Inventor: CASTRICONE JOHN ANGELO
IPC: D06F35/00
Filed: 1955-01-28
Abstract: 770,929. Washing clothes. ALTORFER BROS., CO. Jan. 28, 1955, No. 2690/55. Drawings to Specification. Class 138 (2). In a washing process, the clothes, a soap material, wetting agent or detergent, and a liquid are introduced to a washing zone, and while the liquid level is approximately or less than half the normal liquid level a toroidal flow of the liquid and clothes is commenced by moving an agitating surface in an orbit around a central axis in the washing zone, to produce a thick soap solution which is worked by the toroidal flow through the clothes, and thereafter the liquid is added up to the normal liquid level, the toroidal flow being continued. The washing action is preferably commenced while the liquid level is between one-third and one-half of the normal liquid level. The agitating surface is preferably moved in an orbit without rotary movement about the central axis. The process may be employed in an automatic washing and spin-drying machine, or the liquid may be supplied to the machine manually.

A radio or sonic target locating echo system comprises n transducer elements E1 ... E12 equally spaced around the periphery of a circle and means for phase-modulating the signals received by said elements, or signals derived therefrom, at a modulation frequency f, the phase of the modulations applied to signals derived from any two adjacent elements differing by 360‹/n, and the phasernodulated signals being combined to produce a resultant signal corresponding to that produced by a narrow beam rotating at f c/s.; signals from the transmitter are applied to the transducer elements in the same phase to produce substantially omnidirectional transmission. A plurality of sets of elements may be stacked vertically to provide vertical directivity. As shown, the signals received by the elements E1 . . . E12 are applied directly to corresponding modulators M1 . . . M12 and the modulating frequency f from oscillator 0 is applied to the modulators through a chain of phase shifters S 1 ... S11 each producing a phase-shift of 360‹/n. In a modification, each received signal is applied to a respective frequency changer, the local oscillations (supplied by a common local oscillator) applied to the frequency changers being phase modulated as above; in this case phase modulation may be effected by converting the local oscillation to a saw-tooth pulse train which is applied to an amplitude discriminator whose discrimination level is varied sinusoidally at the modulation frequency f to give a position modulated pulse train which is converted back to a phasemodulated sinusoidal waveform.

Title: Process for improving materials containing polyvinyl derivatives
IPC: D06M11/70
Filed: 1947-02-03
Abstract: The resistance to light of articles having a basis of chlorine-containing vinyl polymers or copolymers is improved by uniformly incorporating in them 0.1 to 10 parts per thousand by weight of compounds of hexavalent chromium.  The process may be carried out by intimately mixing the chromium compound with the polymer before forming the article or incorporating it during manufacture of the article or by treatment of the finished article, e.g. by dipping or spraying.  The treated articles, if desired, may be subjected to treatment with additional agents, e.g. pigments, or natural or synthetic polymers or their derivatives.  The process may be applied to the treatment of films, threads, fibres, artificial horsehair, strips, rods, ribbons, fabrics, filaments, varnishes and foils, having a basis of the polymer.  In examples (1) a mixture of polyvinyl chloride, sodium bichromate, acetone and carbon disulphide is spun; (2) a film is cast from a solution containing polyvinyl chloride, lithium bichromate, acetone and carbon disulphide, and (3) a fabric formed of a copolymer of 85 per cent vinyl chloride and 15 per cent vinyl acetate is soaked in an aqueous acetone solution of potassium bichromate.
