Title: Blades for fluid flow machines such as axial flow turbines
Inventor: BOWMER THOMAS
IPC: F01D5/18
Filed: 1959-12-09
Abstract: 895,077. Turbine blades. ROLLS-ROYCE Ltd. Dec. 2, 1960 [Dec. 9, 1959], No. 41933/59. Class 110 (3). An axial flow turbine blade has an internal passage 14 therethrough for a flow of cooling fluid, a plurality of rows of bars 19, the bars extending across the passage 14, the bars of each row being staggered with respect to those of adjacent rows. Cooling air enters the passage 14 through an aperture 15 and leaves through an aperture 16 in the blade tip. The bars 19 are cast integrally with walls 17, 18 of the blade. The bars 19 may be spaced to limit the flow through the passage 14 to a desired value or to cause increased turbulence at and thereby cool localized hot spots. The bars also increase the heat transfer area of the blade. The invention may be applied to a nozzle guide vane wherein the internal passage extends in the chordwise direction through the central portion only of the vane. A high-pressure turbine blade 23 (Fig. 5) has a central duct 29 which is supplied with cooling air, some of the air escaping through a hole 28 in the tip and the remainder through holes 30, 31. The major portion of the air passes through holes 30 into passages 34, 35 and the baffle bars 38 are relatively closely spaced adjacent the apertures 30 to increase turbulence in the hottest part of the blade. The holes 31 lead to passages, extending along the length of the blade, which have no bars.

Abstract: 976,675. Travelling-wave tubes. RAYTHEON CO. Nov. 9, 1962 [March 22, 1962], No. 42469/62. Heading H1D. A travelling-wave tube functioning as an oscillator and amplifier comprises in the same envelope 1, Fig. 1, first, 9, and second, 10, slow wave structures spatially separated so as to be substantially uncoupled, an electron gun 5 for launching an electron beam 21 passing and interacting with the two structures 9, 10 successively, the first structure 9 operating as an oscillator and the second structure 10 operating as an amplifier and power output source and means for coupling a variable impedance 23 to the first structure to vary the oscillation frequency. The two structures may be separated by a drift section 4, Fig. 1, or the envelope may have an insulating band 55, Fig. 5, enabling the parts 53, 54 of the envelope surrounding the two slow wave structures to be at different potentials, or the drift section may contain one or more electrodes, e.g. 146, 147 in the M-type tube of Fig. 13. The oscillation frequency may be controlled by varying the electrical length of the oscillator slow wave structure as illustrated by connection to a variable load 23 in Fig. 1, 75 in Fig. 5, and 169 in Fig. 13, or, in the arrangement of Fig. 1, by varying the potential between the electron gun 5 and the collector electrode 6, or, where the envelope is divided into two mutually insulated parts, Fig. 5, by varying the potential between the gun 57 and the first wall part 53. The output power may be controlled by varying the potential of the second envelope part 54, Fig. 5, or of the electrodes, e.g. 146, 147, Fig. 13, in the drift space, or, if different potentials are applied to the two electrodes 146 and 147, the beam may be displaced radially giving different intensity coupling to the output slow wave structure 141. One end of the first, oscillator, slow wave structure is connected to a variable load, while the other end may be connected to a matched impedance (78, Fig. 5) or coated with a resistive material, e.g. iron particles or graphite, 157, Fig. 13; similarly for the second, amplifier, slow wave structure. Both sections, normally operate as backward wave tubes. The O-type tube, Fig. 5, has two parallel minorimage electron beams 72 one on each side of the interdigital structure.

Title: Photographic shutter mechanism

Filed: 1972-09-13
Abstract: 1407255 Cameras EASTMAN KODAK CO 13 Sept 1972 [13 Sept 1971 (2)] 42594/72 Heading G2A A camera is operable at high illumination in a first mode in which the shutter opens for a fixed period, at lower illumination in a second mode in which a detent 61 holds the shutter open for a photo-electrically determined period and preferably at even lower illumination in a third mode in which flash is used and the detent holds the shutter open for a photo-electrically determined period adjusted according to object distance. In the first mode a trigger circuit 92 is non-conductive and hence an electromagnet 70 is switched off. When an impeller arm 56 is rotated anti-clockwise to move a shutter actuating lever 58 it allows a spring 76 to rotate an armature 68 clockwise and thereby move the detent 61 to an inoperative position in which it cannot retain the lever 58. Lever 58 is returned by springs (36, 46), Fig.1 (not shown) to close the shutter. In the second mode the trigger circuit 92 is conductive and hence electromagnet 70 is energized to hold armature 68 for a photo-electrically timed period, the dentent 61 retaining lever 58 until armature 68 is released. In the third mode trigger circuit 92 and another trigger circuit (118), Fig.7 (not shown) are conductive, the latter energizing a low light indicator lamp (97). Insertion of a flash-lamp switches a resistor (130) into the control circuit and focusing on close objects switches in a further resistor (131). Shutter operation in the third mode is otherwise the same as in the second. The lamp (97) is extinguished on shutter closure to indicate exposure termination. The shutter of Figs. 1 and 2 (not shown) is claimed in Specification 1407256.
