Title: Improvements in and relating to vacuum distillation
IPC: B01D3/10
Filed: 1934-03-07
Abstract: <PICT:0434726/III/1> <PICT:0434726/III/2> In the high vacuum distillation of liquid materials in which a number of distillation units S1, S2, S3 . . . are housed in a common vacuum chamber 1 connected to a high vacuum pumping system, each unit comprises a distilling surface 3 heated internally by a heater 4 and an adjacent condensing surface 5.  The residue and distillate leave the units respectively at R1, R2 . . . and D1, D2 . . . and are fed to other units or removed from the apparatus. Thus the distillate from S4, enriched in the more volatile components, is fed to S5 while the residue from S4 enriched in the less volatile components is fed to S3 and so on.  The distilling and condensing surfaces, each of independently adjustable temperature, may comprise concentric cylinders, the units being arranged side by side or one above the other, or as in a modification of the invention, the surfaces of each unit comprise vertical plates.  A suitable interchange pump comprises a piston 5 working in a chamber 1, having an inlet 2 and an outlet 3, surrounded by a solenoid 7 which when energized forces the piston down against a spring 8 and transfers a given quantity of liquid from the pump chamber.  The solenoid is de-energized at the end of the pumping stroke.

Patent GB-680475-A (GB)
Title: A process for the manufacture of artificial bristles, hairs, threads or the like
IPC: D01D5/42
Filed: 1950-03-28
Abstract: Artificial bristles, hairs, threads or the like are obtained from scrap photographic film, such as cinema film or X-ray film, by softening the film material with a swelling agent, preferably at elevated temperature, and then cutting it into filamentary form.  The process is applicable to cellulose acetate or nitrate film.  The swelling agent may be a mixture of acetone, amyl acetate, and glacial acetic acid.  When clear products are desired, the emulsion layer is removed, e.g. by treatment with hot water or dilute acid and by treatment with rotary brushes, preferably before the film is cut. The filaments or products such as plaited or woven fabrics made from them may be subjected to treatment with a swelling agent, e.g. acetone, in order to remove any roughness from the cut edges of the filaments.  The hairs, bristles, or threads may be used in making industrial brushes, or artists' brushes, brooms, filter cloths, screens or stiffening fabrics.  They may be mixed with silk, wool, cotton, or other animal or vegetable fibres or yarns.
