A gas turbine engine has at one end thereof a central fairing or bullet member which is supported from the outer casing or wall by one or more struts which extend across the annular passage formed between the central fairing and the outer wall, the fairing and the struts being formed in two or more pieces which are detachable from each other so that when at least one piece is removed, access is given to the interior of the fairing and each strut. In the gas turbine engine shown in Fig. 1 a fairing 17 is disposed centrally within the compressor intake, the fairing being supported from the compressor wall 18 by a pair of hollow struts 19. The fairing is hollow and a starter motor 20 and a fuel control unit 21 are supported therein, the connections to the two units passing through the hollow struts. The fairing is divided at 23 into a forward portion 17a and a rearward portion 17b and each strut is also divided at 32 into a forward portion 19a and a rearward portion 19b, the forward portions of the fairing and struts being formed as a unit, and likewise the rearward portions. The joints between the parts are sealed as shown in Fig. 5, a sealing strip 25 secured to the inner surface of the forward portion 19a extending beyond the joint 23 and being received between a sealing member 26 secured to the inner surface of the rearward portion 19b.

Title: Method and apparatus for analysing a reactive gas
Inventor: OFFUTT ELMER BRADLEY
IPC: G01N21/86
Filed: 1957-05-24
Abstract: Apparatus for the analyzing of the content of a gas stream consists of a transparent, reactive, coating carried by a light-transmitting tape which is moved through a device for adding moisture to said coating and subsequently through a device for impinging a controlled flow of a test-gas sample on the moistened coating before the tape passes through a light-beam the proportion of reactive gas component in the sample being measured by means of a recorder for the output of a photoelectric cell.  Hydrogen sulfide may be analyzed using a coating of lead acetate and sodium acetate in about equimolar amounts.  The moisture may be added by impinging an air stream of controlled humidity against said coating and the test gas stream may also have its humidity controlled; both being maintained at constant temperature.

Title: Improvements in or relating to the production of patterned, minutely-perforated rubber sheet
IPC: B29C37/00
Filed: 1941-12-24
Abstract: 549,282. Rubber sheets. UNITED STATES RUBBER CO. Dec. 24, 1941, No. 16612. Convention date, Jan. 3. [Class 70] In preparing minutely-perforated rubber sheet as described in Specifications 4.16,904 and 419,015, a design is formed on the sheet by unperforated portions surrounding or being surrounded by perforated portions. A backing 1 in the form of an endless band of textile fabric coated with rubber so as not to mask the weave, or of the form described in Specification 535,925, passes round rollers 3, 4, and is coated at parts 9, by a roller 5 which picks up coagulant from a roller 8 in tank 7. The backing is then given a coating of latex from a tank 10 with a spreader bar 12, and is carried through a heating chamber 13. The air enclosed in the small cavities in the backing expands and rises through the latex layer on the untreated parts, and on those parts treated with coagulant the latex is sufficiently coagulated to resist passage of the air. The layer may be stripped from the backing at 15 or may be passed a second time, the coagulant-applying roller 5 being removed. The stripped sheet is dried and vulcanized, and may be used, after treatment by bromination to render it non-adherent to latex films, as a deposition backing for forming patterned perforated sheets application of coagulant being unnecessary in this case. Air or other gas or a fluid coagulant may be forced or drawn through the perforations in the backing.

Title: Improvements in and relating to electric induction motors
IPC: H02K17/18
Filed: 1920-06-19
Abstract: 145,470. Siemens - Schuckertwerke. Jan. 29. 1918, [Convention date]. Alternating-current motors.-The starting torque induction motors is increased by making the ratio e/eo of the slot leakage of the secondary member for alternating-current to the slot leakage for continuous-current equal to or less than 0.5. Curves and formulµ are given to show the relation between this ratio and the conductor and slot dimensions; the conductors may be subdivided to obtain the deaired leakage values. Fig. 1 shows, for various sub-divisions of the conductor bars, the relation between the ratio e/eo and the " numerical bar depth," which latter is derived from a formula given in the Specification. Fig. 3 shows suitable depths of rotor slots. To secure even induced voltages, the conductor may be crossed, interlaced, or twisted. The secondary winding may be of the squirrel-cage type. The starting torque may be further increased by causing the secondary ohmic resistance to vary with the frequency, for instance as described in Specification 146,175. Favourable conditions are obtained when the rotor leakage at rest lies between approximately one-half, and the full stator leahage.

[Class 37] Measuring apparatus for alternating currents comprises in combination means to measure true power, and having an indicator movable in a straight line and means to measure reactive power with an indicator, movable in a straight line at right angles to and over the area traversed by the first indicator. The part A for measuring true power consists of an electromagnet 1 excited by a current coil 2 and a movable coil 3 carrying a current proportional to the voltage. The movable coil 3 is fixed on a spindle 4 and moves against a spring 6. An arm 8 is fixed on the spindle 4 and has at its outer end a toothed sector 9 meshing with a toothed wheel 10 fixed on a spindle 11. This spindle carries a member 12 having a helical groove 13 formed in its surface. A member 14 has a projection which engages the groove 13 and a hole by which it slidably engages a rod 17 fixed in supports 18, 19 in which the spindle 11 is also supported. An indicator 20 carried by the member 14 thus moves in a straight line over a chart 21. The second part B for measuring reactive power is identical with the part A except that the current in the movable coil 3 is proportional to the voltage but is displaced therefrom by 90 degrees. This moves an indicator 22 in a straight line over the chart 21 at right angles to the motion of the indicator 20. The chart 21 is divided below the horizontal diametrical line 26 to provide a scale of imported power and above this line to provide a scale of exported power. The chart 21 is also divided on the left-hand side of the vertical diametrical line 25 to provide a scale of imported reactive power and on the right-hand side of this line to provide a scale of exported reactive power. Scales of leading and lagging power factor are also provided. A series of concentric circles struck about the centre of the chart constitute a scale of current, the length of the line from the centre of the circles to the point of intersection of the indicators being a measure of the current and the angular position of this line indicating the power-factor.

Abstract: 126,745. Marks, E. C. R., (Lasky Feature Play Co.. J. L.). Nov. 14, 1917. Rotary machines; printing processes.-Kinematograph and other long films are coloured by making a negative from a positive film in which the parts to be coloured are stopped out with a material impenetrable by light, immersing the negative in a bichromate or like solution to render the image impervious to liquid, dyeing the portions without image, and bringing the negative and the positive to be coloured into contact in correct register and subjecting them to pressure; the films are brought into contact on the surface of a cylinder, which may be continuously rotated, and one or both of the films may be stretched to obtain correct register. Fig. 7 shows a machine bv which the transfer of colour is effected. The dyed negative film A is wound from a wheel 75 over tensioning-rollers 43, 44, 45 by a toothed drum 15 driven by a handle 24 or other means through worm gearing, and passes around the drum and away from the machine over a roller 80. The positive film B is also drawn through the machine by the drum 15, passing to it, from a receptacle containing a solution for moistening and softening its gelatinous surface, over rollers 40, 41, 42, and passing from it to a drying-reel or to another machine by which another colour is applied. Rollers 25, 26 may be provided for pressing the films on to the drum 15. Means are described for varying the tension of the films produced by the rollers 41, 44 so as to removeinaccuracies of the register due to irregularities in the stretching of the films.
