Title: Improvements in or relating to furnaces
Inventor: QUICKE KENNETH GEORGE
IPC: H05B6/02
Filed: 1951-09-28
Abstract: 743,974. Induction heating. GARRINGTONS, Ltd. Dec. 23, 1952 [Sept. 28, 1951], No. 22651/51. Class 39(3). [Also in Groups XII and XXX] In an electric furnace, which may be of the induction heated type, the article 30, Fig. 3, to be heated is inserted in a cavity in the thin upwardly-projecting part 29 of a pivoted holder 23 which is maintained in the vertical position during its passage through the furnace, but on issuing therefrom turns into the position shown in broken lines 36 to allow the article to be ejected. Each holder 23 is pivoted at 38 to a rotatable disc 15 and is provided with a foot 25 which slides on a rail 26. The holder is supported also by a roller 64 mounted on a pivoted arm 63 which is connected by gears 66, 67 to a shaft 68. An arm 69, Fig. 2, on this shaft is connected by pin-and-slot mechanism to the lever 70 of a damping valve 65 and another arm is connected to a piston-and-cylinder unit 72 which is controlled by a valve 71. The arrangement is such that the maximum angular velocity of a holder is attained when its cavity is horizontal. The disc 15 is advanced intermittently and is retracted to a lesser extent between each forward movement. A gear 20, fast on the shaft 16 carrying the table, is engaged by a pawl 51, Fig. 4, which travels in an arcuate guide 52 and is connected by a link 62 to a pivoted member 53. This member is rocked by fluid-pressure actuated mechanisms 54, 55. Disengagement of the pawl is prevented during two-thirds of its back stroke by a cam plate 61 fixed adjustably to the guide 52. The pneumatic system controlling the units 54, 55 is connected to the valve 71 in such a manner, that actuation of the unit 72 occurs only when the disc has reached the end of its advance in each cycle. A reversing valve 73 is actuated at the end of the downstroke to effect the return of the empty holder to its initial position. The parts 29 travel in a tunnel formed by the field windings 43, 44 of the furnace which are suspended from supports 13 and may be disposed between heat insulating members. Since the ends of the windings are connected by bridge pieces 45, 46, the end portion of the heating zone may be of greater intensity, and the driving mechanism of the disc is therefore arranged to pass the end work holder through this zone to the discharge point so that it is not subjected to the different field.

Title: Improvements in and relating to gas turbine plants
IPC: F02C6/00
Filed: 1949-09-09
Abstract: 691,049. Gas turbine plant. APPIO, G. F. P. Sept. 11, 1950 [Sept. 9, 1949], No. 23359/49. Class 110(iii) In a gas turbine plant comprising two or more turbines or turbine stages, the gas exhausted from the first turbine is expanded to convert its pressure energy into kinetic energy, mixed with additional air and then the kinetic energy of the mixture is re-converted into pressure energy before being fed into further turbines. Air from a compressor is heated in an exhaust gas heat exchanger 2 and a combustion chamber 3 before entering a turbbine 4 driving the compressor. The exhaust from the turbine 4 is expanded through a nozzle 13 into a mixing chamber 12 where air supplied by a fan 14 is mixed with it. The mixture then passes through a venturi tube 16 in the divergent portion 17 of which the kinetic energy of the steam is converted into pressure energy before passing to a second turbine 1. The mixture may be re-heated in a combustion chamber 9. The air supplied by the fan 14 is controlled by a variable orifice situated in its suction or discharge so that the losses in the mixing chamber 12 are minimised. In a modification, a heat exchanger arranged in parallel with the heat exchanger 2 is used to preheat the additional air fed to the mixing chamber. The air in the plant may be heated indirectly instead of directly as shown in a combustion chamber 3.
