Patent GB-414153-A (GB)
Title: Improvements in the manufacture or treatment of textile and other shaped materials and articles made of or containing organic derivatives of cellulose
IPC: D06M13/224
Filed: 1933-02-08
Abstract: Textile materials or other articles of organic derivatives of cellulose, which contain an oil, fat, or the like, are delustred by subjecting them, while in a substantially dry condition, to the action of heat.  Preferably the oil or fat employed is coconut oil, and it may be introduced into the spinning solution from which the filaments and the like are formed.  The quantity of oil used is, for example, from 5--15 per cent relative to the cellulose derivative present.  The application of heat to the materials may be made, for example, by passing in contact with a heated surface, or the materials may be passed around rods or rollers, or between pairs of hollow nipping rollers, either or both of which are internally heated.  The temperature employed is usually about 160--210 DEG  C. The loss of lustre may not be immediate, but may occur only after standing.  The presence of moisture on the material reduces or nullifies the dulling effect of the heat, and differential lustre effects can be obtained by selectively applying moisture to filaments, yarns, or fabrics, prior to the heat treatment.  In an example, a 25 per cent solution of cellulose acetate in acetone-methyl alcohol, containing 10 per cent of coconut oil on the weight of the cellulose acetate, is spun into an evaporative atmosphere, and the filaments formed are passed around a roller heated to 195 DEG  C.  By suitable adjustment of the speed of the heated roller and the feed roller, the filaments may be stretched.

Title: Improved clothes-washing machine
Inventor: BERTER SVEN
IPC: D06F34/06
Filed: 1957-02-12
Abstract: 819,327. Automatic washing machines. HUSQVARNA VAPENFABRIKS A.B. Feb. 12, 1957, No. 4830/57. Class 138 (2). A washing machine having a tub fitted with an electric motor driven washing basket and an immersion heater is controlled by a motordriven timer adapted to stop itself and the washing basket a predetermined time after initiation of the washing cycle, so that heating of the wash liquid is continued without agitation until the temperature has reached a desired level when a thermostatically operated switch re-starts the timer and agitator. As shown, a clothes washing machine comprises a tub 37 having a washing basket 36 driven by motor 20 through gears 35 which, when the motor revolves in one direction, drive the basket 36 at washing speed, and when the motor reverses, drive the basket at a high speed for spin-drying. The tub 37 contains a water heater 21, the output of which may be varied by changing its connections or which may be interchanged for another of different output controlled by thermostats 3 and 5, and is fitted with a drain pump 25 and an electromagnetically-operated inlet valve 22 which is operated by float 23 in the tub and an associated switch 24. The machine is automatically controlled by motor 16 driving timer'15, switches 1, 2, 6, 7, 9, 10, 11 and 12, relay 28 and the thermostats 3 and 5; to initiate washing the main switch 31 is closed and the shaft of timer 15 is manually rotated until the timer motor 16 starts. The operating cycle consists of a sixminute soaking period in cold water after which the water is drained and extracted from the clothes; cold water containing a detergent is then added and the articles are tumbled by rotation of the basket 36 whilst the heater 21 is operating. After three minutes the timer and washing motor are stopped and heating continues without agitation until the water temperature reaches 35 C. when the thermostat 3 re-starts the timer and wash motor, and three five-minute wash periods each separated by one minute rest follow, during which time heater 21 operates continuously. After the last washing period wash motor 20 remains stationary until the wash water reaches its desired maximum temperature, e.g. 85 C., and thermostat 5 cuts off heater 21. The clothes are then tumbled for a further four minutes after which the wash water is drained, the articles are rinsed four times and then finally spin-dried for four minutes. For clothes requiring lower washing temperatures, a greater part of the tumbling can be restricted to temperatures below 35 C. by short-circuiting the thermostat 3 with switch 32 which cuts out the timer's first period of rest.
