Abstract: 1,255,268. Filtration, dialysis. UNITED STATES ATOMIC ENERGY COMMISSION. 10 March, 1969 [12 April, 1968], No. 12508/69. Headings B1D and B1X. A layer of filter aid is formed on the upstream side of a tubular filter element and used as a base on which a dialysis membrane is subsequently deposited directly from the liquid being purified, dialysis then proceeding with a substantial flow (1 to 100 feet/sec.) of incoming liquid across the membrane to prevent solids build up thereon. The effect may be enhanced by turbulence promoters. The filter element may be sintered metal, ceramic, carbon or woven cloth such as a fire hose jacket. Filter aid may be asbestos or cellulose fibres, carbon, perlite, silica gel or diatomaceous earth, and may be deposited in three successive layers of different particle sizes (exemplified). In examples, a MgCl 2  solution was separated using a membrane formed by adding hydrous Zr (IV) oxide to the solution. Sewage effluent was purified using a membrane consisting of material originating from the effluent itself. Another membrane, comprising mixed poly (vinyl pyridine) and poly (vinyl pyrrolidone) deposited on a perlite filter aid layer, supported on a porous stainless steel tube of 10Á pore diameter, was used to separate salt solution. The filter aid particles are 0.01 to 100Á in diameter and form a bed 0.1 to 100Á thick.

Title: Improvements in multiple control apparatus for electric railways
IPC: B60L15/32
Filed: 1922-05-08
Abstract: 194,974. Akt.-Ges. Brown, Boveri, et Cie. April 1, 1922, [Convention date]. Controllers, pneumatic actuating mechanism; master control systems.-Multiple unit controllers on electric trams are operated by compressed air cylinders a<1>, a<2> furnished with electromagnetically-operated valves d, e which admit compressed air to a cylinder when the corresponding magnet is energized and exhaust the cylinder when the magnet is de-energized. A master controller S co-operating with hunting-switch brushcontacts i, h, k causes a rack b to be moved any selected number of steps to the left from the zero position shown, the main controller being driven through a pinion c. The stoppage at the selected position is brought about by the agency of the hunting-switch contacts, which results in the admission of compressed air to the cylinder a<2> without exhausting the compressed air from the cylinder a<1>. When the master controller is turned to zero, all the valve magnets are de-energized, but the valve e is kept down by a separate spring-piston q so that compressed air in the cylinder a<2> returns the rack to the position shown. One double-acting cylinder may replace the two single-acting cylinders. Automatic control of the rate of starting may be obtained by arranging the hunting-switch contacts in conjunction with a current-limit relay which interrupts the step-by-step movement of the rack until the motor current is sufficiently reduced. In addition, a push button relay may be provided to allow the driver to continue the movement of the rack in single steps.
