Title: Process for making ethylene diamine by treating ethylene dichloride with ammonia, and separation of vinyl chloride from ammonia
IPC: C01C1/02
Filed: 1960-09-24
Abstract: A process of purifying recycle ammonia containing vinyl chloride by-product from the production of ethylene diamine from ammonia and ethylene dichloride, comprises absorbing the crude ammonia gas in a first pressure-tight absorber in an aqueous ammoniacal solution under an elevated pressure below that of the stage to which the ammonia is recycled, and then absorbing any residual ammonia gas in a second absorber under atmospheric pressure in water, vinyl chloride being vented from the second absorber. In the drawing impure gaseous ammonia at 10 atmospheres pressure enters absorber 2 via pipe 1, and is partially absorbed in 24% aqueous ammonia which enters via pipe 7. Absorber 2 operates at 6 atmospheres and 40 DEG C. Unabsorbed ammonia and vinyl chloride leave the top of absorber 2 via pipe 3 and enter the second absorber 14 operating at atmospheric pressure and 40 DEG C. Vinyl chloride leaves the top of tower 14 via vent 19 while the residual ammonia is completely absorbed in water fed to the top of absorber 14 via pipe 13. The solution drawn off the bottom of this absorber circulates through cooler 18 and re-enters absorber 14 about 2/3 of the way up it. 24% ammonia solution is drawn off absorber 14 through an overflow pipe 4 into a reserve 5 <PICT:0956283/C1/1> whence via pump 6 and pipe 7 it passes to junction 11 where it meets hot solution leaving the first absorber 2. The two solutions are mixed, cooled in cooler 8 and pumped to the top of absorber 2. 35% ammonia solution is discharged from the bottom of absorber 2 via pump L into a pipe 12, and after addition of anhydrous ammonia or water to bring it to the desired concentration may be employed in treating ethylene dichloride.

Title: Process for the heated drawing and fixation of filaments
IPC: D02J1/22
Filed: 1967-07-10
Abstract: In a process for the heat treatment of synthetic filaments and threads so that they may be stretched, set, and optionally shrunk in one working step, the filaments are passed over first and second heated rollers rotating at different peripheral speeds, the filament or thread is passed through a heating zone between the first and second heated rollers in such a way that in its passage between the two rollers the filament or thread is always at least at the temperature at which it left the first roller, but below the setting temperature of the filament or thread, the temperature of the second roller being sufficient to heat the filament to its setting temperature. Preferably the filament or thread passes through the heating zone without contact with any part of the apparatus, and the heat treatment on the two rollers and in the interposed heating zone is advantageously effected in the absence of air, an air-suction extractor being provided on the housing if desired. Either or each of the first and second heating rollers may be a stepped roller having steps which can be heated to different temperatures. Preferably the second heating roller is a stepped roller having a first step of larger diameter than the second step, so that a reduction in filament speed occurs as the filament passes from the first step to the second step, thus enabling the filament to shrink. The temperature of the two steps of the roller may also differ. Any convenient heating arrangement may be used in the heating zone, infra-red radiation, electrical induction or resistance heating being mentioned. Preferably the ends of the heating arrangement lie as close as possible to the heating rollers. In operation a filament 30 is drawn off by a creel 2, 4 from a supply position (not shown). The filament passes into the housing (not shown) through a slot (not shown) and travels with slight pre-tension over a heated roller 7 and associated guide roller 8. The filament is heated to its drafting temperature whilst on roller 7 and then passes without any contact over a heating arrangement 14 to a heated roller 9 which is maintained at the setting temperature for the filament. If shrinkage of the filament occurs during setting the filament, after travelling over the step 12 and guide roller 10 is guided on to a step 13 of the heated roller which runs at the same rotational speed as step 12 but is of smaller diameter thus enabling the filament to shrink. The filament loops several times around the step 13 of the heated roller and around guide roller 11 before emerging from the protecting and insulating housing (not shown) through a slot at the bottom (not shown).

Patent ES-350005-A1 (ES)
Title: Nuclear reactor fuel elements
IPC: G21C3/26
Filed: 1968-01-31
Abstract: A fuel element comprises particles of ceramic fissile material each having a coating of refractory non-fissile material, which particles are contained in a ceramic container and bonded together in a region about each of their places of contact by a bridge of bonding material of high thermal conductivity, the interspaces between the particles being free of bonding material. In a method of making such a fuel element, particles of uranium carbide each having a coating of pyrolytically deposited carbon are overcoated with a deformable layer of silicon powder by tumbling the particles in a slurry of the silicon powder, a solvent and a binder material, a silicon carbide container is filled with the silicon powder coated particles and the particles are pressed down in the container to deform the layers of silicon powder so that the particles make contact at their carbon coatings. The ceramic container and the particles it contains are then heated to melt the silicon powder so that the molten silicon moves by capillary action to form individual bridges of silicon bonding the particles together in a region about each of their places of contact, and so that by reaction of the silicon with the carbon coating of the particles silicon carbide is formed bonding the particles together at each of their places of contact. The fuel element may be heated in an atmosphere of nitrogen which converts the silicon in the bridges between the particles to silicon nitride. In an alternative method, the particles are overcoated with a solid silicon layer, e.g. by using a heated fluidized bed in which fluidization is by means of a stream of hydrogen containing silicon tetrachloride vapour. The silicon carbide container is first closed at one end by means of a " green " silicon carbide plug formed by diepressing granules made from a slurry of silicon carbide powder and colloidal graphite in a solution of a ceramic binder material. The container is suspended with the plugged end downwards in a L.F. induction furnace containing a crucible of molten silicon which infiltrates the " green " end plug by capillary action and reacts with the carbon. This method of end capping is also used for closing the other end of the container after the bonding of the fuel particles within the container. Other bonding materials, e.g. molybdenum, zirconium or niobium, can be employed and the invention is applicable to the bonding of particles of other fissile materials, e.g. uranium dioxide or nitride, having coatings of silicon carbide, beryllia or alumina.
