Title: Mineralogical analysis
IPC: G01N23/207
Filed: 1964-08-04
Abstract: 1,075,243. Photo-electric bore-hole logging. SOC. NATIONALE DES PETROLES D'AQUITAINE. Aug. 4, 1964 [July 29, 1963], No.30979/64. Heading G1A. The presence of a specific mineral on the wall of a bore-hole or shaft is determined by introducing a source of X-rays or y rays into the shaft, directing it against the wall and detecting any diffracted rays from the wall at a diffraction angle characteristic of the desired mineral. The ray source 1 and detector 4, contained in a probe shown in three parts in Fig. 3, are angularly movable with respect to one another by mounting them on a goniometer. The collimators 2, 4 at the source and detector ensure that the incident beam and the beam received by the detector are parallel and the angle between them defines the diffraction angle. Around the point of incidence the two beams pass through a fluid-filled chamber 10 having a flexible portion 11 at the wall face, both fluid and flexible portion being transparent to the radiation. The pressure of the fluid is such as to press this portion against the wall of the bore-hole so forcing away any mud, which would otherwise absorb the radiation. The probe is equipped with articulated shoes or wheels to align it in the hole and with a knife and rotary brush to clean the rock surface. In the search for a single mineral the probe is lowered with the detector at a fixed angle; but for further minerals the detector is turned through a range of angles at various stages down the hole or a composite probe can be used having a number of source-detector assemblies, each detector set at a different but fixed angle.

Abstract: 973,319. Generating combustion products under pressure; jet propulsion plant. GENERAL ELECTRIC CO. Aug. 15, 1962 [Aug. 17, 1961], No. 31289/62. Headings F1J and F1L. In a fuel injection system fuel from a pressurized source is injected into a supersonic airstream within a tube longitudinally disposed in the airstream, means being provided to decelerate the airstream within the tube to a supersonic speed lower than its initial supersonic speed at entry to the tube, the fuel being injected at the point of the lower supersonic speed. A liquid fuel injector 11, Fig. 3, for a ramjet or similar supersonic engine comprises an upstream directed hollow spike 13 surrounded by a tube 14 having a Venturi inner surface with converging, throat and diverging portions 15, 16, 17 respectively. The form of the spike 13 is such that no shock losses occur and the airstream is still supersonic at the throat 16. Fuel is supplied to the interior of the spike 13 under pressure through line 20 and is injected into the airstream, preferably supersonically to reduce losses, through a converging-diverging opening 19. The size of the opening 19 is such as to ensure a fuel rich mixture in the injector, the opening being of corrugated form in a modification for this purpose, Fig. 5 (not shown). In a further modification a duct 23 extends through the spike 13, shaped to produce a normal shock wave 24 therein and hence to increase the static pressure in the duct 23 and the efficiency of the fuel and air mixing in the diverging portion 17 of the tube 14. The inlet and exit areas of the tube 14 may be equal. The injector 11 may be mounted in the inlet of a supersonic ramjet 10, Fig. 1.

Filed: 1920-11-05
Abstract: 175,359. Cammell, Laird, & Co., Ltd., Carter, Sir G. J., and Ray, L. J. Nov. 5, 1920. Worm pumps.-Lubricant is supplied to gear wheels, e.g. in geared turbines on to the engaging faces of the teeth as they approach the arc of contact automatically in accordance with the direction of rotation, through one or other of two sprayers or sets of sprayers, the reversal of the gear wheels changing the direction of rotation of a lubricant propeller so as to change the direction of flow of the lubricant from one sprayer or sets of sprayers to the other. Two shrouded rotary propellers N<1>, N<2>, Fig. 4, are fixed to the extensions K of the gear shaft A, the lubricant supply G being disposed between the propellers and the outlets E, F axially outside of them. With the shaft A rotating in one direction, the propeller N<1> propels lubricant from supply G to the outlet E leading to one sprayer - or set of sprayers, the propeller N<2> assisting in this action and preventing the flow of lubricant to the outlet F. When the direction of rotation is reversed, the propeller N<2> propels the lubricant to the outlet F leading to the other sprayer or set of sprayers, this action being assisted by the propeller N<1> which prevents flow of lubricant to the outlet E.

Portable wheeled ladder escapes.-A portable wheeled fire-escape is provided with erecting and inclining means which also and at the same time operates to limber the escape to, or unlimber it from, its supporting vehicle. The supporting frame b, c, d of the ladder p is connected to the axle e of the travelling wheels g by a telescopic support f comprising in known manner concentric externally threaded cylinders each working in a nut on the next larger cylinder and adapted to be extended by rotation of the axle e by means of a cranli-handle. The angle of the frame remote from the ladder carries arms l, adapted to engage eyes r on the vehicle F, and an axle a on which are mounted levers m pivoted on the axle e. When the support f is extended the wheels g are first lowered to the ground. The axle a then oscillates about the axle e until the rear wheels h of the ladder engage the ground, when continued extension of the support lifts the arms l from the eyes r and erects the ladder. The ladder is similarly limbered to the vehicle when the support is shortened to collapse the ladder.

Abstract: 784,409. Electronic counting-apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 2, 1954 [Nov. 5, 1953], No. 31691/54. Addition to 710,554, [Group XL (c)]. Class 106 (1). [Also in Group XL (c)] The Figure shows the first, second and last stages of a multi-stable state ring connected counter or storage circuit. Each stage comprises a bi-stable trigger pair circuit, for example that comprising tubes 10, 11 directly connected from anode to grid and also via the cathode-follower stage such as tube 12. Normally all stages are in the OFF condition with the left-hand tubes 10, 41, 50, &c., cut-off and the right-hand tubes 11, 42, 51, &c., conductive. A negative pulse applied to the RING START line 28 triggers over the first stage so that tube 10 is conductive and tube 11 cut-off. Successive positive pulses then applied to TRIGGER INPUT line 30 operate through diodes 25, 39, 40, &c., to reverse the condition of the ON stage to OFF and via, interstage couplings such as 45, 46 to switch the next succeeding stage in the ring to ON. Thus each stage in turn takes up the ON condition with at any instant all the other stages being in the OFF condition and a succession of phase-displaced positive pulses, Fig. 2 (not shown) are generated at OUTPUT 1, 2, &c. An individual stage will only be switched to a second condition when the polarity of the voltage feedback from the right to the left hand tube via the cathode-follower stage is of the same polarity as the voltage on the common trigger lead 30.
