Title: Electric induction lamp
IPC: H01K11/00
Filed: 1956-07-06
Abstract: 806,518. Electric induction lamps. SYLVANIA ELECTRIC PRODUCTS Inc. July 6, 1956 [July 8, 1955], No. 21068/56. Class 39(2) An electric induction lamp comprises a metal member or "target" 3 which is heated to incandescence within a sealed envelope 1 containing a gaseous filling at a pressure above atmospheric pressure by H.F. currents induced within it, the envelope further enclosing a metallic member adapted to concentrate a magnetic field around the target. The target may be made of the carbide of tantalum, hafnium, or niobium, or a mixture of such carbides. In order to concentrate the magnetic field around the target 3 it is located within the central opening 5 of an annular metal disc 6 which forms the substantially closed end of a metal cylinder 8, a radial slot 7 in the disc extending longitudinally down the wall of the cylinder 8 being provided to eliminate any direct short-circuiting loop around the concentrator formed by the cylinder and its end portion. The cylindrical disc comprising the target 3 is of smaller diameter than the opening 5 in which it is located, and is formed with a short integral stem 15 of reduced diameter which provides means for mounting it upon a supporting tube 16 of less refractory material, e.g. zirconia, held within a collar 18 supported at one end of a radial arm or bracket 20, Fig. 3 (not shown) the other end of which is screwed or otherwise secured as the inside wall of the cylinder 8. The cylinder 8 is itself supported by a pair of hollow metal tubes 9, with their lower ends attached to copper thimbles 10 sealed in known manner to the lower end of the glass envelope, the tubes 9 being provided for the purpose of carrying a liquid cooling medium up the inside wall 14 of the cylinder 8 and across the underside of the disc 6, to which they are attached in thermal content by soldering or other means. A metal exhausting and gas-filling tube 23, e.g. of copper, sealed laterally into the wall of one of the thimbles 10 is sealed off in known manner after the envelope has been. filled with argon at a pressure of about 1¢ atmospheres absolute. In operation the high frequency coil 4 which surrounds the glass envelope around the upper region of the tube 8 is connected to a high frequency source, e.g. of four megacycles, thereby heating the target to incandescence at a temperature of about 3600‹K. Light is emitted from the front surface of the target 3 through the optically flat end 2 of the glass envelope. Specification 806,519 is referred to.

Abstract: 350,286. Echo-sounding apparatus. SUBMARINE SIGNAL CO., 160, State Street, Boston, U.S.A.-(Assignees of Turner, E. E. ; 130, Willow Street, West Roxbury, Massachusetts, U.S.A.) July 11, 1930, No. 21078. Convention date, July 29, 1929. [Classes 13 and 118 (ii).] In apparatus for determining depths or distances by the echo-sounding method, the means for measuring the time interval between the sending out cf the sound impulse and the receipt of the echo comprise an indicator which is set in motion at the beginning of the interval and is momentarily illuminated, whilst still moving, at the end of the interval. A lever 13 is rocked by a pin 12 on a rotating disc 11 and returns to its normal position under the action of a spring 14, a hammer 5 then striking against a diaphragm 1 and so causing the emission of a sound impulse. The rocking of the lever 13 also closes contacts 16, 17 and completes a circuit through a coil 18 pivoted to rotate in a magnetic field and carrying a pointer 19. The pointer is thus rotated anticlockwise to its zero position against the action of a spring 20. The contacts 16, 17 open and the pointer commences to move clockwise at the instant the sound is emitted. The echo is received by a receiver 4 and, after amplification by thermionic valve apparatus 23, causes the illumination of a glow tube 27 situated behind the pointer. The tube 27 contains a plate 29 coated on one side with mica and connected to one end of the secondary winding of a transformer 26 and a wire 30 connected to the other end of the same winding. Specification 309,901, [Class 118 (ii), Signals], is referred to.

Title: Cooled Vane Structure for High Temperature Turbine
Inventor: QUINONES ARMANDO JOSEPH
IPC: F01D5/18
Filed: 1967-05-05
Abstract: 1,188,382. Turbine and like blades. GENERAL ELECTRIC CO. May 5, 1967, No.21134/67. Heading F1T. A cooled turbine or like vane comprises a hollow body formed with a plenum chamber having a heat transfer fluid inlet and throttling means for directing the heat transfer fluid against the interior wall of the chamber in the leading edge region of the vane body, and a multiplicity of passages in the leading edge region for inter-connecting the plenum chamber and the exterior wall, the passages being disposed along axes forming acute angles with the plenum chamber walls to discharge the fluid from the chamber in a relatively thin layer over the exterior wall in the leading edge region of the vane body. The invention is described with reference to a vane of an annular nozzle diaphragm of a gas turbine but is equally applicable to the construction of other blades and to vanes used in either high temperature turbomachines, such as high-pressure compressors. The vane body 33 is an aerofoil shaped member, the plenum chamber of which is divided into two regions 50, 51 by a radial partition 52. A serpentine passage is formed downstream of the region 51 by radial partitions 57, 58 dividing the interior of the vane body 33 into two radial passages 60, 61. The partitions 57, 58 not quite extend to the inner base 34 and outer end plate (not shown) respectively so as to form openings 62, 63. Relatively cool compressed air for cooling the vane body 33 is bled from an annular chamber which surrounds the combustion space of the gas turbine and admitted through inlet 55, filling the plenum region 51 and flowing through throttling openings 74 in the partition 52 into the region 50. Rows of radially spaced, small diameter passages 70 a, b, c, in the leading edge region connect the region 50 with the convex side wall surface 45, the concave side wall surface 46, and the leading edge 47 respectively. The axes of the passages 70a, b connecting with the convex and concave surfaces from an acute angle, preferably less than 30 degrees, with these surfaces so that the cooling fluid is discharged axially downstream along the surfaces toward the trailing edge 48. The axes of the remaining passages 70c form an angle of approximately 45 degrees with the leading edge 47 so that the cooling fluid is discharged radially outward along the leading edge 47. Compressed air also enters the serpentine passage through the opening 62, providing convection cooling in the midchord region where the film of cooling fluid begins to separate from the convex and concave side wall surfaces. Convection cooling is provided in the trailing edge region by cooling fluid flowing through small diameter passages 72 extending axially between the radial passage 61 and the trailing edge 48. The convection cooling in the leading edge region is supplemented by boundary layer cooling, the cooling fluid discharged by the passages 70 being trapped in the boundary layer, thus insulating the vane body 33 from the hot combustion products.
