Title: Method of and means for controlling the outlet area of gas turbine jet propulsion engines, equipped with means for allowing an after-combustion
IPC: F23R3/00
Filed: 1950-01-13
Abstract: 666,944. Jet propulsion plant. SVENSKA TURBINFABRIKS AKTIEBOLAGET LJUNGSTROM. Jan. 13, 1950. [Jan, 22, 1949] No. 925/50. Class 110(iii). A gas turbine jet propulsion engine with means for reheating the turbine exhaust gas has a flow of air supplied to the gas jet in such a way that it surrounds wholly or partially the gas jet, which flow of air is throttled or interrupted when the reheat is in operation so as to increase the area available for the gas jet. In the arrangement shown the exhaust gas from the turbine 1 passes through the ports 10 into the duct 6 and from there passes to the propulsion nozzle. During normal operation, a flow of air from the compressor or ram air from the atmosphere is led through a duct 16 to a space 12 from which it flows through the space 13 to surround the gas jet as it passes through the outlet. When fuel is supplied to the duct 6 by the pipe 5 this air flow is throttled or interrupted by the valve 18 so that the area of flow for the 'gas jet is increased from 15 to 17. The duct 6 may be rigidly attached to the turbine casing at the inner end and be free to expand at the outer end. The expansion of this duct when the reheat is turned on may be used to throttle or interrupt the air supply through the space 13. A modification in which this throttling effect is increased by placing a fixed sleeve around the duct and arranging co-operating rows of holes in the sleeve and duct is described. In a further modification, the space 13 is controlled by a sleeve mounted on the end of the duct 6 by links inclined in an angle between 45 degrees and 90 degrees to the duct.

Title: Improvement of surface characteristic of continuous casting steel ingot
Inventor: MIYANO HARUO
IPC: B22D11/04
Filed: 1985-01-08
Abstract: PURPOSE:To prevent the cracking of an ingot and the rupture of a shell in the stage of oscillating vertically a casting mold at a specified pitch and drawing the ingot by oscillating the mold by a nonsinusoidal waveform. CONSTITUTION:The casting mold is so oscillated vertically at the specified speed as to form the nonsinusoidal waveform in the stage of casting continuously a carbon steel, etc. having about 0.08-0.16wt.% carbon content. More specifically, the oscillating speed Vm of the mold is made higher than the drawing speed Vc of the mold to shorten the negative strip time by oscillating the mold in the nonsinusoidal waveform in which the mold is quickly lowered after rising. The relative speed difference (Vm-Vc) between the oscillating speed Vm of the mold and the drawing speed Vc of the mold is thereby decreased, by which the frictional resistance between the mold and the shell is decreased. The casting with high efficiency is thus made possible without the cracking of the ingot and the rupture of the shell and without dropping the casting speed.
