Title: Improvements in or relating to fluid metering devices
Inventor: WINSER EDWARD CHARLES
IPC: F16K1/52
Filed: 1955-09-06
Abstract: 807,956. Valves. BRITISH THERMOSTAT CO. Ltd. Nov. 5, 1956 [Sept. 6, 1955], No. 25564/55. Class 135. The valve body 1 houses a spring-loaded plunger 4 embodying a valve closure 5 and a cam follower 6; the latter co-operates with an edge cam 10 having a stop 11, 12 at each end and a central nick 13. Fluid enters an inlet 2 and flows through a part of the helical groove 17 on the plunger before passing to the outlet 3. Upon moving a lever 9 about an offset pivot 18 to the position shown, the cam slides through a slot in the follower 6 until the stop 12 abuts the follower whereupon the plunger spring 8 forces the plunger 4 to its fully elevated position shown, which provides for " full flow " through the device. With the lever 9 centrally positioned the nick 13 engages the follower and the plunger 4 assumes a " low flow " position. Upon moving the lever 9 to the right towards the " off " position the valve 5 is caused to close the outlet 3 whilst continued lever motion results in the cam 10 rotating about a second pivot 20 against the action of a torsion spring 16 whereupon a cam abutment 21 moves away from a trimming screw 14 so that the spring 16 holds the valve 5 in the closed position. With the device in the " full flow " position the plunger may be removed for cleaning purposes. The fuel flow in either the " low " or " high flow " position may be varied by altering the relative disposition of the plunger and lever, or by adjusting the follower or the trimming screw. Specification 779,612 is referred to.

Abstract: 1,014,170. Photo-electric position finding systems. DE HAVILLAND AIRCRAFT CO. Ltd. July 31, 1959 [Aug. 11, 1958], No. 25801/58. Heading H4D. Radiation, e.g. infra-red, reaching the sensing system of a guided missile is chopped by a rotating reticule 1 in the focal plane of the optical system, so that only radiation from a target produces an A.C. signal from a detector 2. The reticule, Fig. 2, has generally radial blades the spacing of whose edges along a given arc, say B, varies so that the A.C. signal is frequency modulated with a phase depending on the angular position of the target image on the reticule. The native of the modulation is made to vary with the radial distance of the image from the centre of the reticule: at the centre the angular separations of the edges of the blades are equal; from the centre out to arc A the angular widths of the blades vary; from A outwards the angular width of each blade is constant.

Abstract: 465,104. Control of A.C. and D.C. motors. ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. Sept. 20, 1935, No. 26120. Convention date, Sept. 27, 1934. [Class 38 (iii)] The primary winding of an asynchronous motor 4 is fed from a direct-current supply 1 through a grid-controlled inverter 3, and the secondary winding is connected to the supply 1 through a grid-controlled rectifier 5. By regulating the inverter 3 to give a supply at a frequency varying from 200 to 250 cycles and at the same time regulating the rectifier 5 to operate at a frequency varying from 200 to 250 cycles the speed of the motor 4 may be raised from zero to a speed corresponding to 100 cycles. The amount of power returned to the supply through the rectifier 5 may bear a 3 : 2 ratio to the power usefully employed in the motor. The voltage ratio of the converters may be regulated to cause the current to remain constant during the whole starting period. Condensers 7 may be connected across the motor secondary circuit as shown together with inductances and similar provision may be made on the primary side to facilitate the commutation of the converters. The transformers of the converters may be omitted the motor windings being associated directly with the converters. The Specification as open to inspection under Sect. 91 describes a modification in which a commutator motor is connected with a supply through a converter and a further converter is provided in series with the circuit to return a proportion of the power to the supply. This subject-matter does not appear in the Specification as accepted.

Title: Method and apparatus for counting standardization in scintillation spectrometry
IPC: G01T1/202
Filed: 1966-06-13
Abstract: 1,145,713. Scintillation spectrometry. BECKMAN INSTRUMENTS Inc. June 13, 1966 [Aug. 16, 1965], No. 26218/66. Heading G1A. In the scintillation spectrometry of a radioactive test sample dissolved or suspended in a liquid scintillator, a measurement indicating the degree of quenching i. e. the reduction in the light output of the scintillator due to the effects of the test sample itself, causing an overall shift of the pulse height spectrum for the sample to lower energy levels, is obtained by the use of an external standard radio-active source. The measurement is compared with calibration curves to obtain information about the counting efficiencies of the channels used to produce the pulse height specimen for the sample, and thereby obtain a corrected pulse height spectrum. To obtain the measurement which is indicative of the degree of quenching, apparatus comprising two counting channels S u , S L , measuring pulses in adjacent pulse height band widths, sufficiently wide to cover a major part of the pulse height spectrum, is used. First counts are taken over a predetermined time with the test sample only (contained in a liquid scintillator) located in front of the detector (a photo-multiplier) (#-particles from the test sample produce scintillations which are detected by the photo-multiplier). The count in each channel is made either forwards or backwards on a scaler 26 u , 26 L , Secondly counts are taken over the same time as before with the sample and the standard radio-active source in front of the detector. For example, a Cesium-137 source, may be used omitting y-radiation which produces Compton scattered electrons from the sample in a spectrum of similar form to that produced by the sample itself. These cause the scintillator to emit light in proportion to the incident electron energy. These second counts are made backwards or forwards on scalers 26 u , 26 L , depending on the direction of counting during the first counts, so that the counts previously recorded for the sample alone are cancelled, and final values for the standard source only, are obtained in the scalers. The outputs of the scalers thus represent the count rates in the two channels S u  and S L  and are divided one by the other to obtain a ratio which is indicated at 30. This ratio is the required measurement representing the degree of quenching by the sample and is then referred to calibration curves, which have been obtained previously using samples of known degrees of quenching, and the counting efficiencies of the channels read off.

Abstract: 773,375. Moulding metal powder. IMPERIAL CHEMICAL INDUSTRIES, Ltd. Sept. 9, 1955 [Sept. 10, 1954], No. 26263/54. Class 87(2). In making metal strip from metal powder the powder is converted into the fluidized state before being passed to compacting means. Fig. 1 shows a fluidizing chamber 1 having a perforated false bottom 2 below which is a space 5 into which compressed air or other gas is blown. Metal powder is fed from a hopper 8 onto the false bottom and is converted into the fluidized condition by the air passing through the holes in the false bottom. The powder falls over a lip 12 onto a carrier metal strip 14 and is pressed, with the strip, between rolls 16, 17. Means may be provided to confine the powder laterally on the strip. To compensate for the spreading effect of the rolls on the powder, the column of powder 13 issuing from lip 12 is deeper at the centre than at the edges ; for the same reason, in the modified outlet shown in Fig. 3, comprising holes in the end wall of chamber 1, the holes are closer together at the centre than at the ends. The strip made from the powder may be removed from the carrier strip or allowed to remain on the latter to form a composite strip which is further compacted. In a modification, Fig. 4 (not shown) the carrier strip is omitted, the powder being fed down a perforated shoot directly into the bight of the rolls.
