Title: Apparatus for estimating stress relaxation and variation in modulus of materials
Inventor: GERALD NORMAN
IPC: G01N3/08
Filed: 1968-06-19
Abstract: 1275262 Testing materials B P CHEMICALS INTERNATIONAL Ltd 17 June 1969 [19 June 1968] 29098/68 Addition to 1123213 Heading G1S An apparatus for estimating relaxation and variation in the modulus of materials comprises a pivoted balance arm 4 having means 2 to hold the test material 3, means 6 for applying tension to the arm, means for increasing and decreasing the applied tension to return the arm to the undisplaced position and means for recording the tension. The tension of spring 6 is varied by movement of nut 7 along threaded rod 8 which may be turned in either direction by reversible motor 9. The motor may only stop when beam 13 interrupts light from 12 passing to photo-cell 32 so that the tension is varied in equal steps corresponding to one revolution of the shaft of motor 10, the number of units of tension being recorded on counter 14. Arm 4 carries a piece 18 which interrupts light from source 16 to photo-cell 15 when the arm 4 is in a displaced position, causing the control circuit to energise motor 10. To measure relaxation, specimen 3 surrounded by oven 11 is stressed by action of fluid activated piston 33 in cylinder 19, causing part 18 to activate motor 10 until the arm is returned to the undisplaced position by increase of tension in spring 6. As specimen 3 extends due to relaxation, part 18 again activates motor 10, which turns one revolution which is sufficient to withdraw part 18 from the light path thus decreasing the tension by one unit. The tension and the time are printed out in recorder 14 at each reduction of tension. To measure the modules of specimen 3, at times determined by timer 23, a predetermined strain is applied to specimen 3 and the arm balanced as above. The time and stress are then printed out, and the strain removed from the specimen. The control circuit allows the measurements to be carried out automatically. A transducer may be attached to the arm pivot 5, or to depending arm 17 and coupled via a suitable conditioning device to a recorder to record the movement of the arm.

Filed: 1946-10-02
Abstract: 617,475. Gas turbine plant. JUDSON, C. A. Oct. 2, 1946, No. 29430. [Class 110 (iii)] In a nozzle guide vane assembly for a gas turbine comprising a plurality of segments, each of which consists of an inner and outer blade mounting platform connected by the nozzle guide vanes, the outer platforms are formed with outwardly directed splines or teeth and an axial spigot which engage corresponding formations on the stationary turbine structure to locate the outer platforms axially, radially and circumferentially and the inner platforms are provided on the surface remote from the vanes with a spigot which engages an inner ring so as to allow radial expansion of the vane whilst locating the inner platform circumferentially and axially. The nozzle guide vanes 25 are formed with inner and outer platforms 26, 27 which are of part-circular form and when assembled form annular rings. An axial extension 28 of'the outer platform 27 forms a shroud for the blading of the disc 19 and carries a radial flange 29. This flange is provided, on its periphery, with teeth or splines 33 which engage corresponding teeth or splines 34 on an outer supporting ring 35 and, on its forward face, with a spigot 30 which engages in a recess 31 of a spigot ring 32 clamped between the supporting flange 24 and the outer supporting ring 35. The outer platforms are thus located axially, radially and circumferentially in the supporting structure. The outer supporting ring 35 is spaced away from the platforms 27 to provide a space for stagnant gas or a passage for cooling air. The rearward ends of the platforms 27 are supported by spigots 38 which engage a spigot ring 39 attached to the outer supporting ring 35. The shrouding 40 of the low-pressure turbine is also supported from the ring 39 by a spigot and by a further spigot 44 which engages a flange of a ring member 43 forming part of the casing. The inner platforms 26 are formed with inwardly directed flanges 45 which when assembled form a continuous flange which enters a peripheral groove 46 in a sealing diaphragm 47.
