Filed: 1968-05-03
Abstract: 1,224,233. X-ray fluorescence analysis. OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AEROSPATIALES. May 3, 1968 [May 5, 1967; April 5, 1968], No.21103/68. Heading G1A. A material is investigated by electron induced X-ray fluorescence whilst being subjected to heattreatment by the electron beam. A surface 54, Fig. 17, under treatment is irradiated by an electron gun 75 and fluorescent X-rays are detected by spectrometers 70, 70<SP>1</SP> sensitive to the L rays of different constituents of the material and aligned with the same point on the surface. The gun is first controlled by function generators 77, 78 to scan in x and y directions in turn to determine the co-ordinates of the point at which spectrometers 70, 70<SP>1</SP> respond. These co-ordinates are then stored at 84 and 85. The gun is then controlled by the function generator 76 so that the beam moves along a locus to effect the required heat-treatment. For a short period each cycle, the gun is controlled by the generator 79 which deflects the beam to the point at which the spectrometers 70, 70<SP>1</SP> respond so that the quotient of their signals may be indicated and recorded or used to control the addition of one of the constituents to the sample of material being treated. The spectrometers 70, 70<SP>1</SP> may be moved by motors 93 under control of a programmer 95.

Title: Improvements in a combined device of a ship's propeller enclosed by a nozzle
IPC: B63H5/14
Filed: 1934-07-19
Abstract: 443,362. Propelling ships. KORT, L., 7, Jakobistrasse, Hanover, Germany. July 19, 1934, No. 21195. Convention date, July 25, 1933. [Class 114] Screw propellers are disposed within tubular nozzles of which the cross sectional areas toward the outlet are constant and toward the inlet increase rapidly. the inlet of the mouth being rounded off with sectional curves of comparatively large radii, and the nozzle is disposed adjacent to the hull which is shaped so as to direct the inflowing stream axially. The propeller placed in the position CB of minimum cross-sectional area in a nozzle from which a flow is directed to an outlet D of equal area and into which it is directed jointly by the shaped hull to the opening and rim of the nozzle the inlet area being greater than the area at B. The outside of the nozzle tapers to an angle 8. In order that the flow is not impeded the sectional form departs from that of a circle in the vicinity of the hull and extends upwardly in the form of lobes. In modifications with twin propellers the hull is extended to form the middle partition, and in some cases the twin nozzles are merged into one at their outlet. Each nozzle may be provided with a flap 2 hinged at 3 whereby the inlet area is adjustable. In other modifications, only a part of the nozzle in the vicinity of the propeller completely surrounds the propeller, the hull itself being arched forwardly at 6 with an edge 7 partly vertical and partly horizontal. In addition there may be a rearwardly extending upper shield with partly vertical and partly horizontal edge walls. In one construction a single engine is used to drive two propeller shafts through gears 17, these shafts begin arranged divergently. The propeller blades are formed of less pitch at their roots and tips than at their middle, and the pitch increases from the leading to the trailing edge.

Title: Improvements relating to hydraulic speed governors for prime movers
Inventor: IFIELD RICHARD JOSEPH
IPC: F02D1/12
Filed: 1949-08-22
Abstract: 674,132. Gas turbine plant. LUCAS, Ltd., J. Aug. 17,1950 [Aug. 22, 1949], No. 21713/49. Class 110(iii) [Also in Group XXIX] In a hydraulic speed governor of the kind adapted to control a liquid-operated servomotor e for controlling the fuel supply to a jet propulsion engine, a gas turbine or like prime mover, the servomotor control valve o is actuated by liquid-operable means such as the diaphragm t (or a piston) subject to the pressure in a byepass passage 8, 7, 6, extending from the fuel supply system and containing an adjustable throttle 4 actuated by a dashpot piston 10 responsive to the liquid pressure in the byepass passage, and means are provided to set up a counterpressure in the byepass passage which is related to the speed of the prime mover. The byepass passage is temporarily closed by an isolating valve 14 while the prime mover is being started. As shown the servomotor e controls the inclination of the swashplate d of a multi-cylinder pump as described in Specification 577,016, [Group XXIX], but it may operate a throttle or a byepass valve in the fuel supply. The control valve o is carried by a spring-loaded lever p and actuated through a stem w by the liquid pressure in a chamber s acting on the diaphragm t against a tension spring u. The pump is driven from the prime mover and by means of radial passages y in its rotor a a counter pressure is created in the byepass passage and the chamber s which is related to engine speed. The throttle 4 slides in a cylindrical orifice 5 with tapered grooves. The dashpot piston 10 has a restricted orifice 11 and is loaded by an adjustable tension spring 12. The isolating valve 14 is carried by a diaphragm 16 (or piston) loaded by a compression spring 19 and also by the pump inlet pressure through a pipe- 18. The valve 14 is normally held open by the pump delivery pressure acting through the pipe 8, but remains closed to prevent loss of fuel through the byepass passage while the prime mover is being started. The control valve o responds immediately to a change in the counter pressure and therefore to a change in the speed of the prime mover and at a slower rate determined by the dashpot to changes in the fuel delivery pressure.
