Title: Gas turbine with combustion chambers controlled by valves - which are operated by cams mounted on main shaft
IPC: F02C/
Filed: 1978-12-07
Granted: 1985-12-02
Abstract: A gas turbine has an axial compressor (2) mounted on a shaft (1) which carries a rotor (3) with overhanging blades (4). A mixture of air and fuel is drawn in through the inlet (21) and delivered to an annulus (8, 9) in a stationary cylindrical block (5). Poppet valves (10) actuated by cams (15) allow the charge to flow into combustion chambers (6). The mixture is ignited by means of a sparking plug which causes a rise in pressure. The outlet valve (11) is then opened by the cam (16) and the gas flows out through the tangential nozzle (13) to impinge on the blades (4).

Abstract: Disclosed is a method of treating a free-radical-containing, optionally room-temperature-aged, irradiated, normally solid high-molecular-weight, semi-crystalline propylene polymer material at about from 40 DEG C to 110 DEG C for at least about 10 minutes before being exposed to the higher temperatures that deactivate the residual free radicals therein. Treatment of the polymer at the intermediate temperature causes recombination, and better utilization, of free radicals with the production of more long-chain branching. A two-stage fluid bed process, with a first stage at the intermediate temperature for radical recombination and a second radical-deactivation stage at a higher temperature, is preferred.
