Title: Improvements in apparatus for carrying out x-ray fluorescence analysis
IPC: G01N23/223
Filed: 1961-05-29
Abstract: 933,458. X-ray diffraction apparatus. PHILIPS ELECTRICAL INDUSTRIES Ltd. May 29, 1961 [June 1, 1960], No. 19295/61. Class 98 (1). An X-ray diffraction apparatus has more than one diffracting crystal, or differing lattice spacings, and a single radiation detector, the crystals being displaceable so that any of them can be introduced into the beam at the same impingement angle. X-rays from a source 1 strike a specimen 2; the secondary X-rays produced impinge on a crystal, and are reflected to be received by a counter 7. In the form shown, two crystals 14, 15 are mounted side by side on a shaft 12, which can be displaced axially so as to bring either crystal into the beam. The counter 7 is displaced along a scale 9 to a suitable position for receiving the reflected beam. The two crystals are selected so that for different wavelengths # in the Bragg formula n#+2d sin #, the angle # is substantially the same. Thus by displacing one or other crystal into the beam path, without altering the position of detector 7, radiation of two different wavelengths produced by specimen 2 can be observed. Examples of various pairs of crystals are given, with the types of radiation for which they are suitable.

June 27, 1930, No. 19600. Convention date, Oct. 30, 1929. [Class 74 (ii).] In a fabric composed of courses of single yarn d alternating with courses of plated yarn or of two series of plated yarns laid in alternately, each yarn in the plated course is brought to the face in turn, in accordance with the design required. The other yarns of the course either float or are reversely plated. A yarn a is fed in such a way as to float unless needles are deflected inwardly at that point by a cam 22. Plating and backing yarns b, c are fed at the same point. These yarns are under decreasing tensions in the order a, b, c and are knitted in that order when the cam 22 is in action. If certain needles are deflected inwardly by a cam 20 while the cam 22 is still in action the yarns are reversed at those points in the order c, b, a. If both cams 20, 22 are retracted the yarn a floats while b plates on c If cam 20 is in while cam 22 is out of action, c still floats but c plates on b. At the second feed another group of yarns is similarly controlled or a single yarn d is fed, to produce a " grating " effect. Two yarns, alternately floated may be fed in place of the one yarn a. Specification 332,588, [Class 74 (ii), Knitting &c.], is referred to.

Title: Fuel jettisoning valve arrangement for aircraft
IPC: B64D37/26
Filed: 1933-07-11
Abstract: 417,350. Valves. BLACKBURN AEROPLANE & MOTOR CO., Ltd., and RENNIE, J. D., Seaplane Base, Brough, near Hull. July 11, 1933, No. 19612. [Class 135.] The invention comprises means, for opening a fuel jettisoning valve for aircraft, operable by stored power and controlled from a distance, and also similar means operable by fluid pressure governed by electrical remote-control means. The fuel jettisoning valve b, Fig. 1, slides in a bracket c and by means of a rod b<1>, Fig. 3, is connected to a crank b<2> on the shaft of which are two pinions meshing with racks d, e integral with power pistons d<1>, e<1> respectively. Oil under pressure from a bottle g<4> subject on its free surface to the pressure of compressed air in a cylinder j is admitted to one of the power cylinders d<2>, e<2> by means of pipes g<2>, g<3> controlled by valves (not shown) whose stems g<5>, g<6> are operatively connected to solenoids g<7>, g<8> under the control of switches h<1>, h<2> and a master switch i by which the accumulator i<1> can be cut out. The pipes g<2>, g<3> are respectively connected to inlets g, g<1> in a valve block f forming an extension of the bracket c. Pressure oil admitted at g passes through a port #<2>, Fig. 6, into the cylinder d<2> to operate the piston d<1> which closes the valve b, and simultaneously acts on a piston f<1> connected to a spring-pressed exhaust valve f<3> so that pressure oil in the cylinder e<2> may escape into the fuel tank by the port f<5>. The inlet g<1> supplying the valve-opening cylinder e<2> similarly connects with a piston operating the exhaust valve for the cylinder d<2>. A spring arm (not shown) on the end of the crankshaft tends to keep the crank in its highest or lowest positions corresponding respectively to the fully open and closed positions of the valve. Small holes d<3>, Fig. 3, in the pistons prevent the operation of the valve b due to leakage through the pipes g<2>, g<3>. Additional switches h3, h' and h<5>, h<6> on the pilot's switchboard h control the jettisoning valves of lateral tanks, and compressed air is supplied to these valves by pipes j<2>, j<3>. Instead of compressed air, the oil pressure of the engine lubricating system or the pressure derived from a hand-operated pump may be used. Alternatively, the crankshaft may be operated by a loaded spring with a release mechanism comprising a solenoid.

Abstract: 576,244. Brake signals. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., KERSHAW, A. G., and SIMMONS, A. W. Nov. 25, 1943, No. 19709. [Class 105] [Also in Group XXXIV] In a railway braking-system wherein two independent devices are used for controlling the application or release of the brakes in accordance with the speed, a warning of the failure of one of the devices is given in the cab or other point of control. In Fig. 1, failure of one of the devices 1, 2 results in the movement of one only instead of both, of the pistons 7, 8 of the valve 6, and the rocker 21 is swung to lift a spring-loaded vent valve 22 connected to the cylinder 23 of a warning-device 24. Main reservoir pressure is applied at 26 and is exerted on both sides of the piston 25, the restricted passage 27 connecting the supply passage 26 with the upper cylinder space. When the valve 22 is lifted the upper cylinder space is vented and the piston 25 rises against the spring 28. This puts the whistle 30 into direct communication with 'the inlet 26. In Fig. 3, the brake regulation is effected by two sets of solenoid valves 58A-61A, 58B-61B which are operated in sequence according to the speed. The contacts 66, 68 of the valves are interconnected by wires of a lamp circuit so that, if one valve fails to function when it should do so, the circuit is broken and the warning lamp 67 goes out.

Abstract: 859,514. Preparing fibres for spinning in continuous steps; regulating draft. BRITISH COTTON INDUSTRY RESEARCH ASSOCIATION. June 5, 1959 [June 19, 1958], No. 19735/58. Classes 120(1), 120(2) and 120(3). Fibres are carded and drafted in continuous sequence by superimposing webs delivered from carding machines and forming the webs into a single lap which is drafted in such manner that a lap of constant characterists is always produced. As it is automatically doffed from a scutcher S, Fig. 5, each lap is deposited in a pan 103 that is thereupon depressed and operates a switch to start the drive to a chain 107 which progresses the pan to the top of a run-way 108 where it is held in a full pan reserve behind a gate 109. When a carding engine C in a battery of twelve requires a lap, the gate 109 releases a full pan which is then carried by a chain 102 to the appropriate carding engine to deposit its lap on an automatic creel arrangement. Alongside the output ends of the carding engines is arranged an endless conveyer on which are superimposed the output webs (as distinct from slivers) that have been slightly drafted by sets of rollers mounted on the carding engines. Curved guide plates direct the webs from the drafting rollers to the conveyers. The twelve superimposed webs pass from the conveyer through a lap-forming machine L, Fig. 1, comprising drafting rollers, calender rollers and bobbin support rollers. Means are provided for controlling the draft at the lap-forming machine to compensate for reduced thickness of the composite web, if, for example, a carding engine is out of commission for cleaning or adjustment. Full bobbins from the lap-forming machine L are doffed automatically and fed to eight draw frames F in similar manner to the conveyance of the scutcher laps. Further processing may be by (a) draw frame slivers to yarns by conventional methods, or (b) winding slivers on bobbins for automatic doffing and distribution.
