Title: Tertiary amylene concentration
IPC: C07C7/171
Filed: 1960-04-13
Abstract: Tertiary amylenes are separated from hydrocarbon mixtures also containing normal amylenes by absorbing in 40-70% by weight concentration aqueous sulphuric acid at -10 to 20 DEG C., separating the fat acid and intimately contacting it with an inert hydrocarbon, separable from tertiary amylenes by distillation, for less than 15 minutes at 30-90 DEG C. and separating the hydrocarbon phase now containing tertiary amylenes; preferably the time spent at 30-90 DEG C. in contact with the acid should be sufficiently short to prevent excessive polymerization.  Each extraction may be effected in one or more stages, countercurrent technique being used for two or more stages.  An acid to feed ratio of 1-6 parts of acid per part by weight of tertiary amylene is used, preferably with the hydrocarbon as the continuous phase. The inert hydrocarbon may be hexane or octane and any polymeric material formed may also be used.  A weight ratio to tertiary amylene in the feed of 2-8:1 may be used.  Intense mixing is preferred and the contacting may be effected in a rotating disc contactor; vaporous inert hydrocarbon may be added to several points to maintain the temperature.  The mixture is preferably cooled to below 30 DEG C. before separating to minimise polymerization.  The tertiary amylenes are recovered by distillation.

IPC: B64D17/64
Abstract: 133,734. Calthrop, E. R. Sept. 16, 1918. Parachutes.-A parachute-launching device is provided with one or more auxiliary parachutes carried on the aviator and adapted to be expanded as he throws himself from the machine so as to create sufficient resistance to launch the main parachute in the case of a nose-dive. In the form shown, an auxiliary parachute 5 is normally housed within the lining 3 of a pocket 1 adapted to be carried on the aviator, for example like a knapsack. The apex of the lining 3 is connected by a cord 4 to a point 14 on the suspension rope 8 of the main parachute 15. The cord 7 of the auxiliary parachute is also connected to the point 14, and a resilient device 13 is inserted in the rope 8 between the point 14 and the aviator's harness. In the case of a nose-dive, the aviator jumps from the aircraft, thereby straining the device 13 sufficiently to cause a pull on the cord 4, which turns the lining 3 inside-out, thus ejecting the auxiliary parachute, which, on opening, provides sufficient resistance to cause the withdrawal of the main parachute from its container on the aircraft. The cord 4 may also be arranged to be pulled by the aviator. In a modification, shown in the Specification applied to a parachute of the kind described in Specification 131,939, a second auxiliary parachute, contained in the aviator's pocket, is first ejected by him as he jumps from the machine, and thereby effects the opening of the other auxiliary parachute.
