Title: Improvements in or relating to angular rate gyroscopes
IPC: G01C19/42
Filed: 1946-07-02
Abstract: 617,108. Fluid-pressure servomotor-control systems. SPERRY GYROSCOPE CO., lnc. July 2, 1946, No. 19823. Convention date, July 2, 1945. [Class 135] [Also in Group XX] The gunbal frame 16 of a rate-of-turn gyroscope is mounted for oscillation about axis 12 on a spring support comprising a pair of parallel leaf springs normal to the axis 12, two adjacent ends of the springs being fixed respectively to the frame 16 and a rigid support 17 and the two other ends being connected together by a spacing member 15. Preferably, the thickness of the spacing member 15 is equal to the length of the unsupported part of the springs. Angular movement of the frame 16 about axis 12 is detected by a differential airflow pick-off device which comprises shutters 26, 25 rigidly secured to a shaft 27 extending from the gimbal frame and co-operating with air jets from nozzles 33, 34 and 31, 32 respectively. Nozzles 33, 34 terminate pipes 38 and 36 leading to the relay valve 39 which controls a servomotor 60 for the rudder R and to a rateof-turn indicator 65. Nozzles 31, 32 are connected as bleeds to pipes 38 and 36 and are situated in a chamber 29, the pressure inside which is adjusted, by needle valve 53, to be intermediate between that of the instrument chamber 13 and the outside atmosphere. Rotation of the shaft 27 causes blade 26 to close either nozzle 33 or 34 at the same time as blade 25 opens the associated nozzle. 31 or 32, thus causing a differential air flow responsive to the rate of turn.

Title: Improvements relating to coupling devices for high frequency electrical circuits
Inventor: SCANTLEBURY GORDON SIDNEY PENG
IPC: H01P5/18
Filed: 1960-06-07
Abstract: 986,494. Waveguide directional couplers; magnetrons; travelling-wave tubes; klystrons. ELECTRIC & MUSICAL INDUSTRIES Ltd. May. 31, 1961 [June 7, 1960], No. 19864/60. Headings H1D and H1W. A directional coupler comprises two rectangular waveguide sections 1, 2 coupled by apertures 9 in a common narrow wall. The apertures are sealed by dielectric material e.g. ceramic discs and the input side of the coupler forms part of the envelope of a klystron, travelling-wave tube or magnetron. The coupler shown is of the whole-power type in which a progressive transfer of energy is achieved by gradual variation of propagation and coupling parameters. Thus, the outer walls of the sections are distorted to achieve a variation in width indicated in Fig. 2, where the three sections are taken on lines a, b, c of Fig. 1. At the two extremities of the coupling section the phase propagation constants are unequal and the apertures 9 are dimensioned to provide minimum coupling. At the centre, the propagation constants are equal and the coupling is a maximum. If the input is applied at the port 3, the characteristic coupled mode propagated is the high velocity mode, and if applied at the port 5, is the low velocity mode. In either case, an energy transfer, indicated in Fig. 2 by electric field intensity curves, takes place.

Title: Improvements in or relating to processes and apparatus for determining the presence of combustible substances in a gas
IPC: G01N31/12
Filed: 1957-06-24
Abstract: <PICT:0861467/III/1> Arranged at the end 1 of a cylinder 2 is the hot transfer point of a thermo-couple element 3, to which is connected a voltage-controlled indicator 4.  The bulb 7 is used to aspirate the gas sample into the cylinder 2.  Then the valves 5a and 5b are closed.  The pressure-producing valve 16 is so adjusted that a pressure of 150 atmospheres, for example, prevails in the container 14.  Then the quick-operating valve 13 is suddenly opened, and as a result the piston 9 is suddenly moved towards the left until the pressure of the spring 10 and the pressure of the gas sample to the left of the piston are counterbalanced by the pressure of the gas to the right of the piston, for example by a pressure of 100 atmospheres.  The piston 11 will then be situated in the position 9a illustrated in chain lines.  This compression-ignition phase results in the gas present being burned with or without a catalyst which aids but does not initiate combustion.  The indicator 14 is so graduated that it indicates the temperature difference between that due to the heat actually produced and that which would be expected due to the heat produced by compression only.  The difference in the aforementioned heat quantities could be indicated, or the indicator 4 could be graduated directly in gas percentages.  A test tube for determining the presence of carbon dioxide or the like could be connected to the pipe 16, so that after the valve 5a is opened, the compressed gas sample flows, at a speed which is fixed by the passage of the valve, through the test tube which measures directly the proportion of products of combustion or by a thermo-colour. Alternatively, a storage container for high pressure oxygencontaining gases is connected, preferably by way of a quick-operating valve, to a chamber which receives the sample to be tested, the chamber not containing a piston, and which is heated by compression heating of the sample due to the entry of the high pressure gas.

Title: Apparatus and method for Measuring Temperatures
Inventor: MURRAY THOMAS PATRICK
IPC: G01J5/52
Filed: 1967-05-01
Abstract: 1,180,792. Measuring temperature photoelectrically. UNITED STATES STEEL CORP. May 1, 1967 [May 12, 1966], No.20059/67. Heading G1A. The temperature of a hot body is determined by analyzing the potarization in a beam formed by the radiation from the work piece and the reflection from the workpiece of radiation directed on to its surface by a black body having means for heating it to a temperature which is known, the absence of polarization occuring, according to Kirchoff's theorem when the two temperatures are equal. The combined beam is applied to an infrared responsive photo-conductor through a motor driven polarized disc and the absence of polarization may be detected by the disappearance of alternating current from the detector output or by detecting the point of change of phase. In a modification the motor driving the polarized disc may drive the wiper of a potentiometer to produce a sinusoidal waveform which passes through its maximum when the polarization of the analyzer disc is parallel with the plane of incidence of radiation from the black body. A comparison of the phase of the generated signal with that of the detector output indicates whether the workpiece is hotter or colder than the black body and the valve of the output of a phase discriminator may be used to indicate the temperature difference. The beam is restricted by a small aperture and a wavelength filter, and the apparatus described incorporates a double beam oscilloscope for phase comparison, and signal strength estimation. The black body which is apertured may be electrically heated as desired.

Title: Improvements in and relating to the preparation and purification of antibiotics
Inventor: BUSHBY STANLEY ROBERT MORRIS
Filed: 1948-08-05
Abstract: Polymyxin B or E or both is or are recovered from mixtures containing either or both of them and one or more of polymyxins A, C and D by treating an aqueous or alcoholic (e.g. methanolic) solution of the hydrochlorides or other salts of the mixed antibiotics with an alkali until the pH is 8.5-11.0(preferably 10.0-10.5), removing the resulting precipitate, washing it (e.g. with water or organic solvents) and redissolving it in an acid. The alkali employed may be any one which will give the desired pH, e.g. aqueous ammonia or preferably aqueous sodium carbonate, conveniently containing 20 per cent by weight of anhydrous sodium carbonate.  In an example, a mixture of polymyxin hydrochlorides having an activity of 6000-7000 units per mg. is dissolved in water, potassium oxalate is added until no further precipitation occurs, the deposit is removed by centrifuging, sodium carbonate solution is added, the procipitate is collected, washed with sodium carbonate solution, with water and with methanol, and, if desired, with isopropyl alcohol and with acetone, dissolved in hydrochloric acid and the solution freeze dried.  For further purification, the freeze drying may be preceded by reprecipitation with sodium carbonate and re-solution in hydrochloric acid, or followed by dissolving the product in methanol and precipitating it by pouring the solution into dry acetone.
