Patent ES-379890-A1 (ES)
Title: Improvements in or relating to washing machines
IPC: D06F37/22
Filed: 1970-05-21
Abstract: In a method of using a washing and spin drying machine comprising a resiliently mounted tub accommodating a drum which is rotatable about a horizontal spindle, an electric motor for driving the drum at a washing speed and at a spin drying speed, a constant ratio transmission between the motor and the drum spindle, and water supply and drain means, after the washing operation (e.g. 50 r.p.m.) when the motor is changed over to the spin drying speed and the drum is accelerated with the tub still full of water an intermediate speed (e.g. 70 r.p.m.) is attained at which the torque delivered to the spindle and the. reaction torque are balanced until the water in the tub has been driven into rotation when the reaction torque is reduced and the drum acceleration continues. The drum accelerates through the critical speed range of 100 to 160 rpm to a second intermediate speed (e.g. 200 to 300 r.p.m.) when the drum may be balanced by introducing water into chambers secured to the drum. On draining of the water within the drum, the drum accelerates finally to the spin drying speed (e.g. 1000 r.p.m.). Although the pump may be switched on at the beginning of the spin drying cycle or when either of the intermediate speeds is attained, due to a time lag in its effective operation, the tub is not drained before the second intermediate speed is attained. As shown the tub is suspended by helical springs and is provided with dampers. The motor may be an AC motor with two windings or may be a permanent-magnet induction direct current motor fed by an electronic speed control device. The latter motor may be connected in series with a heater for the tub and braking may be effected by causing the motor to act as a generator for the heater.

Patent ES-443569-A1 (ES)
Title: Textile printing process and transfer medium
IPC: B41F16/00
Filed: 1975-12-17
Abstract: An offset process for printing multicolor patterns on fabric. The method involves the photographic preparation of out-of-balance, halftone, color separations and the photoengraving of planographic printing plates for producing a out-of-balance ink dot pattern on a support or transfer medium. The out-of-balance dot pattern compensates for vapor phase expansion of the ink dots upon subsequent transference to the fabric. The pattern is transferred from the transfer medium by pressure contact at its interface with the fabric and upon the simultaneous application of heat for a prescribed time duration, which causes the ink dots to sublimate into the fabric and thereby imprint a continuous tone, multicolor pattern on the fabric. Further correction factors are introduced to compensate for sublimation characteristics of particular ink color pigmentations and for increasing color contrast.

Patent ES-452940-A1 (ES)
Title: Method and apparatus for the treatment of gases containing soluble compounds
IPC: B01D50/00
Filed: 1976-11-03
Abstract: A column-type apparatus for treatment of a gas stream with liquid includes a gas inlet for introducing a gas stream containing soluble compounds and solid particles into the apparatus and simultaneously imparting a cyclonic and upward flow to the gas stream. A gas-liquid mixing section above the gas inlet contains a liquid dispersing device from which liquid is vertically dispersed from the upper portion of the gas-liquid mixing section and flows downwardly and counter-currently to the gas flow wherein all the material entrained within the gas stream is completely and intimately contacted with the liquid. In a gas-liquid separating section above the mixing section, the cyclonic and upward flow of the gas stream causes separation of vesicles formed in the mixing section and solid particles entrained therein by centrifuging and impinging the vesicles onto the interior wall of the column, causing the vesicles to coalesce and form a continuous and downwardly flowing film of liquid on the interior wall of the column, which collects in a liquid collection section. The thus treated gas, free of soluble compounds and solid particles, flows through a gas outlet section. The apparatus is useful in any process involving gaseous streams containing soluble compounds, and particularly for absorptions involving chemical reactions or requiring less than a theoretical plate.
