Abstract: 930,231. Automatic temperature control. PHILCO CORPORATION. Oct. 14, 1959 [Oct. 20, 1958], No. 34808/59. Class 38 (4). [Also in Group XIII] In electrical apparatus for drying by means of a heated gaseous medium, the heating is so controlled by thermally responsive devices that the temperature of the medium initially rises to a predetermined value and thereafter oscillates between limits the upper of which is less than the predetermined value. Fig. 1 shows a sectional side elevaton of a combined washing machine and dryer of the type in which fabrics inserted through an opening 21 are tumbled in a perforated drum 13 which is rotated about a horizontal axis 14 by a motor 15. Air heated by an electric heater 24 mounted within an outer cylindrical casing 20 is circulated by virtue of an oppositely located water vapour condenser cooler 26 and rotation of the drum. Bi-metallic thermally responsive switches 27, 29 inserted through casing 20 to be responsive to air temperature within the dryer are connected in parallel, Fig. 3, and control the energization of heater 24. Energization is initiated by moving a manually operated switch 34 from its off position to the position shown and when a predetermined high temperature is reached thermal switch 29 opens to de-energize heater 24. The temperature then falls until thermal switch 27 closes. Thereafter thermal switch 27 operates for a period determined by a time switch 31, to maintain air temperature between limits which are within the limits of thermal switch 29. Manual switch 34 may be operated to its third position to change over to different close limits determined by a thermal switch 28. A further thermal switch 30 which opens at a high temperature is provided as a safeguard. In a modification, heater 24 is controlled through an electromagnetic relay and instead of de-energizing the heater the voltage applied to it is reduced.

Patent GB-921108-A (GB)
IPC: B05D1/24
Filed: 1959-10-16
Abstract: <PICT:0921108/III/1> <PICT:0921108/III/2> A spray-coating method comprises producing an aerated bed of particulate coating material in an aerating vessel, the degree of aeration being below the limit at which a substantial part of the material becomes entrained in the aerating medium, withdrawing a stream of the aerated material from the vessel propelled entirely by the difference between the bed pressure in the vessel at the locality of withdrawal and the atmospheric pressure outside the vessel, and feeding the said stream to means for forwarding and discharging the material on to the article to be coated.  As shown in Fig. 1, air or gas under pressure is passed through an inlet 2 into a gas box 1, and passes in finely dispersed form through a filter 3 into two aerating vessels 4 and 5. The vessel 4 may contain a powder suitable for prime coatings and the vessel 5 powder for the final coatings.  The degree of aeration may be such as to cause the powder to become fully fluidized, or may produce a static aerate condition in which the material is highly mobile when mechanically disturbed but has a certain angle of repose, lower than that of the unaerated powder, there being no, or very little, relative movement between adjoining particles while the bed is undisturbed.  A filter cloth 6 prevents escape of entrained particles and causes a back-pressure to build up.  Each aerating vessel has a slot 7 closeable by a slide 8, powder issuing from the slots being picked up by a funnel 9 and forwarded by a booster fan 10 through a flexible pipe 11 to a nozzle which discharges it on to a pre-heated article which is to be coated.  The nozzle adaptor 13 (Fig. 4) may have a deflector plate 14 to produce a fan-shaped spray, or may produce an undeflected conical spray. Alternatively a flame-spraying attachment may be used.  In an alternative form of apparatus, aeration may be carried out at a higher pressure in a closed vessel provided with a pressure gauge and a relief valve, and the aerated powder discharged directly into pipes controlled by valves, the booster fan being omitted. Besides air, an inert aerating medium such as nitrogen, carbon dioxide or a suitable industrial waste gas may be used, and the powder may be pre-heated either by heating the aerating vessel or by using a heated aerating medium. Thermoplastic powders which may be sprayed include polyethylene, polyamides and polyvinyl resins; or particles such as glass beads and sand may be sprayed on to tacky surfaces.  The article to be coated may be heated under a canopy, which may be doublewalled, and into which a gas burner is directed.  Specification 912,464 is referred to.
