Title: Method for the bithermal isotopic enrichment of ammonia with deuterium
IPC: B01D47/00
Filed: 1960-08-13
Abstract: <PICT:0951791/C1/1> In a method of enrichment of ammonia in deuterium by a dual-temperature isotopic exchange between liquid ammonia and a gaseous phase comprising hydrogen (e.g. hydrogen or ammonia synthesis gas), in which the gaseous phase is saturated by direct contact in a scparate exchanger with the vapour of the liquid phase which contains a non-volatile alkali metal amide as a catalyst of the isotopic exchange, liquid ammonia containing catalyst circulating in a closed circuit to make up the quantity of ammonia removed in the saturated gaseous phase, the accumulation of non-volatile dissolve catalyst is avoided by introducing into the circuit a make-up quantity of liquid ammonia containing catalyst, said quantity being equal to the quantity necessary for saturation of the gaseous phase plus a quantity which is at least adequate to allow, by withdrawal of the liquid having the most catalyst, at a point of the circuit located adjacent to the outlet of the separate exchange, the removal of a quantity of catalyst which is at least equal to the quantity which has been introduced with the make-up liquid. In Fig. 2, ammonia leaves cold tower F and enters hot tower 1 via 3, and travels via 4 and 5 to tower 2 which is the separate exchanger for saturating the gaseous phase. The gaseous phase enter tower 2 via 6 and trowels via 7 to hot tower 1 and then via 9, heat exchanger 10, and 11 to the cold tower F. A closed circuit of liquid ammonia containing catalyst comprises tube 15, tower 2, tube 12, heat exchanger 10, tube 13, and reheater 14. In tower 2 part of the ammonia is removed in the gaseous phase. The circulating ammonia is supplemented by that leaving hot tower 1 via tube 5, and a conduit 16 in tube 12 is used to drain off ammonia which is more concentrated in catalyst than that entering tower 2. Thus the build-up of catalyst in the circulating ammonia is avoided.

Title: Process for making shaped cellular articles from foamable thermoplastic alkenyl aromatic resins
IPC: B29C44/58
Filed: 1962-02-16
Abstract: A process for the production of expanded or foamed articles in a mould comprises placing a mass of a solid, particulate, thermoplastic polymer composition, which is capable of thermal foaming or expansion by virture of a contact of a volatile organic expanding agent which is not a solvent for the polymer, into the mould and subjecting the mass of the polymer composition to a first heating by passing a liquid gaseous or vaporous heating medium through the mass until the individual particles in the polymer composition are heated throughout to a temperature above the boiling point of the volatile organic expanding agent, which temperature is lower than that at which the polymer composition softens or at which the individual particles flow together or adhere to one another and thereafter subjecting the polymer composition to a second heating at a higher temperature at which foaming or expansion and fusion between the particles takes place. The method is particularly effective when the particulate thermoplastic polymer composition has been partially prefoamed and is capable of further foaming or expansion. Suitable polymers are polystyrene, polyvinyl chloride, copolymers of vinyl and vinylidene chloride, polyacrylic esters and copolymers of styrene and methyl methacrylate, acrylonitrile or natural or synthetic rubber, and especially polymers or copolymers of monovinyl aromatic compounds. The gaseous heating medium may be saturated or superheated steam or steam in admixture with inert gases such as air, carbon, dioxide, nitrogen, methane, ethane, propane, butane and/or helium. In examples the process is applied to beads of styrene and styrene-acrylonitrile copolymer containing pentane. Heating is effected by evacuating the mould and then using steam first at an absolute pressure of 150 mm. and than at 3 lbs. s.i. guage. After moulding the chamber surrounding the mould is again evacuated to cause drying and cooling of the moulded body by vaporization and removal of the water.

Title: Centrifuge separation and washing device and method
IPC: B01D21/26
Filed: 1975-10-08
Abstract: A centrifuge device and method are provided for separating and/or washing finely-divided solid particulate material suspended in a liquid. The invention is especially useful in so treating blood. The centrifuge forms a dense suspension of blood cells in a plurality of blood cells receiving means evenly spaced about the periphery of a rotatable enclosure. The receiving means have converging walls which at their juncture form a locus of maximum centrifugal force. Wash liquid is passed through the dense suspension of blood cells counter to the direction of the centrifugal force by entry into the blood cell receiving means at the locus of maximum centrifugal force. Independent conduits connect the locus of maximum centrifugal force through an injector to a supply for the wash liquid and, after fully resuspending the blood cells in a suitable resuspending liquid, the resuspended cells exit from the centrifuge via the independent conduits and injector, which have also therefore been washed by the wash liquid. Thus recontamination is avoided. A unitary disposable structure including the enclosure, blood cell receiving means, conduits and injector is also provided.
