Title: Stator vane assembly for axial flow compressors
IPC: F01D9/04
Filed: 1957-11-29
Abstract: 845,325. Axial-flow compressor stator casings. GENERAL ELECTRIC CO. Nov. 29, 1957 [Dec. 18, 1956], No. 37271/57. Classes 110 (1) and 110 (3). In a stator assembly of a multi-stage axialflow compressor comprising a casing and a plurality of stator vanes mounted on support rings spaced inwardly from the casing, the space between the casing and the support rings is subdivided into a separate compartment for each row of blades, and the support rings are urged radially inwardly by the pressure of working fluid bled from the stages corresponding to the respective blade rows. The compressor shown comprises a casing 20 formed in two halves, the flanges 10 of which are secured together by bolts 12. The casing parts are formed with internal, annular ribs 22 of T-section and with ribs 44. The stator vanes 58 are mounted in support rings 60 which are also formed of two semi-circular parts, two rows of vanes being mounted in each ring, and the support rings are located within the casing 20 by means of the ribs 22. Each support ring 60 is formed at its ends with annular axially-projecting flanges 64 and at its mid-portion with an annular, radially-projecting rib 90. Upon assembly, the flanges 64 of the support rings engage the T- section ribs 22 of the casing 20 as shown in Fig. 6 and the ribs 90 bear axially against the sides of the ribs 44 as shown in Fig. 7. The support ring 82 at the downstream end of the compressor is not provided with an intermediate rib and the two rows of stator vanes carried thereby are spaced closely together axially, as a row of rotor vanes is not disposed therebetween. The flanges 64 of the downstream end support ring 82 are so dimensioned that no radial clearance is provided between the flanges and the recesses in the T-section rib 22 and in the casing flange 56. Annular spaces 110 are provided between the casing 20, vane support rings 60 and the ribs 22, and 44 and openings 120 are provided in the support rings 60 at the downstream end of each of these spaces so that air under pressure flows from the compressor working passage into the spaces and so exerts a radially inward force on the support rings. The support rings 60 are prevented from circumferential movement by means of strips which bear against the ends of the semi-circular halves of the rings and are received in recesses in the casing flanges 10.

Title: Improvements in or relating to photographic cameras
IPC: G03B19/12
Filed: 1946-12-20
Abstract: 637,858. Photographic reflex cameras. KODAK, Ltd. Dec. 20, 1946, No. 37579. Convention date, April 4. [Class 98 (i)] A roll-film reflex camera has a latch which holds the mirror in its inoperative position after an exposure until released by movement of the film winding mechanism. The construction of the camera is described in Specification 637,859. As shown, Fig. 7, the mirror 43 is fast with a shaft 42 journalled in the walls 40 of the inner body member 20. An arm. 44, Fig. 5, on the end of the shaft 43 protruding through the wall 40 has a pivoted plate 46, further from the wall 40 than the nose 45 of the arm 44. When the mirror is swung upwardly just before an exposure, the nose 45, which is bevelled, lifts and passes under a bolt 38 sliding in holes 39. A lever 31 pivoted at 32 above the take-up spool chamber 5 engages a slot 37 in the bolt 38, which is thus urged by a spring 35 towards the wall 40, and falls behind the nose 45 as seen in Fig. 5, so that the mirror cannot be lowered until the bolt is disengaged. When the film winding knob is operated, one of a number of studs 30, on the underside thereof bears against a lug 34 on the lever 31 to move it and retract the bolt 38 so that the plate 46 is moved by a spring 47 up to the nose 45, preventing the bolt from returning and enabling the mirror to be lowered. The end 52 of the lever 31 projects through a slot in the camera body to enable the bolt to be disengaged without winding the film, if desired.

Title: A Pressure Roll.
IPC: B30B3/04
Filed: 1967-08-16
Abstract: 1,182,165. Rollers. BELOIT CORP. 16 Aug., 1967 [16 June, 1967], No. 37737/67. Heading F2U. To vary the pressure between two rolls 2, 34 in a machine for pressing flexible materials, e.g. paper or textiles, the roll 2 comprises a shell 4 rotatably mounted in brackets 16 on a frame, and a shaft 6 rigidly carried by rods 24 on the frame, the shaft carrying magnetic means 8 eccentrically within the shell to attract one side of the shell towards the shaft and hence to force the diametrically opposite side into contact with roll 34. The magnetic means 8 may be a permanent magnet, a single electromagnet, or a plurality of series-connected electromagnets, and the current to the electromagnets may be varied to vary the force exerted by the shell 4 on the roll 34. This force may alternatively, or additionally, be varied, to take account of varying thickness and/or density of the flexible material, by means of a strain gauge 32 which, on any change in the pressure between shell 4 and roll 34 from a preset value, automatically actuates a motor 30 to adjust a bar 28 to raise or lower arms 26 carrying rods 24. To compensate for any deflection of the roll 2 due to its ends being fixed, the shaft 6 is attached at each end to mountings 18 which in turn are attached to a tension bar 20 provided with an adjustment 22, the bar 20 exerting a force on the shaft mountings in opposition to the stress created by magnet 8. The tension bar may therefore be utilized to give no deflection of the shaft when the magnetic force is exerted, or to give a positive or negative crown to the roll. Cooling or heating fluid may flow through either roll 2 or 34. When the roll 2 is utilized for heating or cooling, the fluid may be introduced and withdrawn at one or both ends, the inlets or outlets being formed at the top or bottom of the roll respectively. The flexible material may be forcibly drawn through the gap between the rolls, or either roll may be driven.

As described the uprights 5 consists of telescopic portions 6, 7 and the semi-uprights 11 consists of telescopic portions 11a, 11b which allow the heights of the hand-rails 2, 3 to be adjusted. In its simplest form the pivot 12 at the base of semi-upright 9 consists of a single pivot pin 18. As the semi-upright 9 is pivoted about pin 18 to alter the spacings of the hand-rails 2, 3 the telescopic bar 14 maintains the upper semi-upright 11 approximately vertical. When the spacing of the hand-rails 2, 3 has been adjusted the telecsopic bar 14 is locked and tensioning cables 19 are tightened. In a modification (Fig 4) the pivot 12 is of the double type and consists of a first member 22 pivoted to the stand 4 by pin 23 and a second member 24 which is pivoted to the member 22 by pin 25 and which is integral with the base of semi-upright 9. The distance L between the pins 23, 25 is half the range of adjustment of the spacing between the hand-rails 2, 3 and the lower semi-upright 9 is located half way between the pins 23, 25 when it is vertical. This arrangement reduces the variation in height of the hand-rail 3 as its spacing is adjusted.
