Ethane is recovered from natural gas and ethane and ethylene from refinery gas in a cyclic system by passing the feed stream 1 to adsorber 16 by line 2. The ethylene and/or ethane deficient effluent leaves the system by lines 22 and 44. At the same time, loaded bed 18 is heated, desorbed and regenerated with heated residue flowing in a closed circuit from heater 19, lines 11, 7, 14 and 4, adsorber 18, lines 24, 34, 27, 31; 35, 45, 43 and 40 and back to heater 19. As the bed 18 is described and pressure in this closed circuit rises above a predetermined value, ethylene- and/or ethaneenriched product gas is bled off through line 36. While bed 16 is sorbing and bed 18 is being desorbed, bed 17, which has previously been desorbed, is being cooled prior to being brought on-stream. This is achieved by means of residue gas, a part of which is diverted from line 44 through lines 46 and 47, cooler 20 and lines 15, 9, 13 and 3 to bed 17, and thence by lines 23, 33, 29, 38 and 39 back to residue gasline 44.

Patent GB-1541369-A (GB)
Title: False-twisting devices
IPC: D02G1/08
Filed: 1977-09-19
Abstract: The apparatus possesses two parallel rotary shafts (1, 2), of which one carries a main friction body (3) in the form of a ball, an ellipsoid or an ellipsoid-like body having at least one annular groove (4) extending transversely relative to this rotary shaft, while on the other rotary shaft (2) is seated a secondary friction body (15, 16) having at least one circular or annular disc (16) which extends transversely relative to this rotary shaft and engages in the annular groove of the main friction body. The part of the rotary shaft of the main friction body projecting from the latter serves as guide means for supplying or removing the yarn. The problem here is that in the event of a break, the yarn immediately winds round this rotary shaft, and this can result in damage to the apparatus as a result of a jamming of the bearing of the rotary shaft. For the purpose of avoiding this disadvantage, there is provided a fixed cylindrical guide sleeve (28) which is coaxial with the rotary shaft of the main friction body and is made of wear-resistant material, for example hard metal, and of which one end is fastened to a fixed part (31) of the apparatus and the other end partially projects into the main friction body. <IMAGE>

[Also in Divisions C2 and F3] An explosive delay initiator comprises a priming charge and a delay burning composition which comprises a metal salt of trinitrotoluene (TNT). The preferred salts are of sodium, potassium and lead. Other metals are barium, aluminium, iron, copper and silver, or mixtures of the salts may be used. The mono- and disubstituted alkali metal salts and alkaline earth metal salts may be prepared by reacting TNT with a hydroxide or alkoxide of the metal; e.g. TNT dissolved in methanol may be treated with an equimolar amount of sodium methoxide in 25% solution in methanol, the methanol evaporated and the residue slurried with benzene to remove unreacted TNT and recover the monosodium salt. Heavy metal salts may be prepared by a metathesis reaction between such an alkali metal salt and a water-soluble salt of the heavy metal e.g. a nitrate, sulfate, chloride or acetate. The device is intended for low delays e.g. 25 or 50 milliseconds, and the salt is preferably mixed with a burning rate modifier such as dibasic lead phosphite (DLP). The modifier may instead be an oxidizer, such as a chlorate, e.g. sodium or potassium chlorate, potassium or other perchlorate or permanganate, barium or other peroxide, a nitrate, e.g. ammonium or sodium nitrate, or mixtures thereof.
