Abstract: 101,544. Bertsch, J, C. Sept. 1, 1915, [Convention date]. Refrigerating, vacuum machines and processes for.-A refrigerating-agent heavier than water and having a boiling-point lower than that of water but above the highest temperature of the atmosphere is evaporated in a closed vessel under a lower pressure than that of the atmosphere, the vapour being exhausted by a pump, with or without the assistance of a steam or air ejector, and discharged below the level of a lubricating-liquid of lower specific gravity contained in a condenser open to the atmosphere. In the arrangement described, carbon tetrachloride is employed as the refrigerant and water or glycerine or a mixture of water and glycerine as the lubricant. The liquid refrigerator is poured into a condenser 11 contaiiiing the lubricant, the condenser having a vent pipe 12 and a cooling-coil 13. The refrigerant passes from the bottom bf the condenser through a pipe 6 and a regulating-valve 5 into an evaporator 1, a spraying-device being fitted at the end of the pipe 6. Brine &c. to be cooled circulates through a coil 2, and the vapour from the evaporator is exhausted by a rotary or other exhausting-pump 10 and discharged through a rose 1'7 into the liquid in the condenser. Lubricant flows by gravity from the condenser through a valved pipe 19 into the exhauster, the action of which may be assisted by an ejector 20 supplied with air from a compressor on the shaft of the exhauster. The apparatus is specially adapted for domestic use, and the use of a heavy refrigerant at low pressure minimizes the risk of fire or explosion.

Abstract: 1,061,342. Tubular films. KOKOKU RAYON & PULP CO. Ltd. March 30, 1965 [Sept. 21, 1964], No. 13472/65. Heading B5B. [Also in Division G3] In a method of monitoring the diameter of an extruded, inflated tubular film prior to cooling, the diameter is sensed by optical means which act on a controlling device to adjust the flow of fluid causing inflation and thus restore the diameter of the tube to within predetermined limits. The monitoring may be effected before or after preliminary air cooling. In one embodiment, a molten tubular film, extruded from annular die (1) (Fig. 1, not shown) is cooled by air ring (3) and then cooled internally by passage over liquid-cooled mandrel (5) and externally by liquid bath (4). The film emerges from flexible baffle 11 and is collapsed between plates (12). The diameter-monitoring system comprises a stabilized light source (15) projecting a light beam of constant intensity to a photo-cell (16) and mounted such that the light beam passes tangentially to the film (14) (Fig. 2, not shown). Photo-cell (16) is connected serially to a meter relay (17), control circuit (18), and an electromagnetically operated valve located in inlet (6) of annular die (1) which controls the amount of inflating air admitted to the tube. In further embodiments, cooling mandrel (5) may be filled with a cooling liquid, e.g. silicone oil, into which air is blown, pinch rollers (13) may be mounted inside tank (94), which may be of frustoconical shape. The apparatus may also be mounted horizontally.
