Title: Stator vane assemblies for axial-flow compressors or turbines
IPC: F01D9/04
Filed: 1958-08-13
Abstract: 840,873. Elastic fluid turbines ; compressors. GENERAL MOTORS CORPORATION. Aug. 13, 1958 [Aug. 13, 1957], No. 25987/58. Class 110 (3). A stator. vane assembly of an axial now compressor or turbine comprises an outer shroud ring, an inner shroud ring and stator vanes connecting the two rings, the assembly being made up of segments which are secured together at the ends of the inner shroud ring portions by a coupling-device which draws together those ends. The device may comprise, Fig. 5, a screw 57 and nut 58 on which are mounted, respectively, wedge members 53, 54 having ramp surfaces 56 which engage with corresponding ramp surfaces 52 on two I-section tongues 51 secured to one segment of the inner shroud member 47 and surfaces ona similar tongue 49 disposed between the tongues 51 and secured to the adjacent segment of the member 47. As the nut is tightened on the screw the wedging action of the members draws the ends of the segments together. In another embodiment, Fig. 10, in which the I-section tongues and the wedging members are of solid, instead of sheet-metal, construction, the wedge 82 is threaded to receive the bolt 84. In a third embodiment, Fig. 8, the opposed ends of two adjacent segments of the inner shroud member 47 carry channel-section tongues 63, 64, respectively, the tongue 64 extending within the tongue 63. The upstanding flanges of each tongue are notched to provide tapered slots 68, 69 which are engaged by a wedge 71. The wedge is drawn into the slots, by a bolt 72 engaging a nut 73, to draw the ends of the segments together. In a fourth embodiment, Fig. 12, also providedwith interfitting tongues, the wedge 99 is tapped to receive the bolt 102. The stator vane assembly is axially located in the casing by circumferential ribs secured to that casing. Keys are secured to the outer shroud ring and engage with the casing and the ribs to secure the assembly against rotation.

Abstract: 192,992. Brown, L., and Macintosh & Co., Ltd., C. Sept. 28, 1922. Tyre attachments to rims.-The metal foundation-bands c of a rubber tyre a, cf the type having a continuous air-space b, are locked against relative transverse displacement by an expansible and contractible ring e. In the construction shown in Fig. 1, the ring e (divided as at f) is formed with flanges g and a central rib d between which the bands c are held and spaced. In the modification shown in Fig. 2, the locking-ring e is recessed into the adjacent edges of the bands c, which are formed with protective side-flanges o. 193,037. Moody, H. N. Feb. 9, 1922, [Convention date]. Detachable-rim attachments to wheels.-The detachable rim 5 (shown constructed to carry twin solid tyres 6) is fitted with internal lugs 10 adapted to engage between lugs 7, 8 on the fixed rim 3 in the manner of the bayonet-joint. The circumferential movement of the rim 5 may be effected by driving taper pins 30 between blocks 28 or 29 on the detachable rim and blocks 27 on the fixed rim. In use, the rim 5 may be locked in its operative position by bending-over the forward ends 33 of the pins 30. For properly centering the rim 5, the lugs 10 may be arranged to ride up wedge seatings 34 fitted between the lugs 7, 8. The circumferential movements of the rim 5 may also be effected by means of a radial bolt 19 having a cam-head 14 engaging thrust-blocks 12, 13 carried by the rim 5. For locking the bolt in its operative position, a washer 23 (keyed to the bolt) and the inner ends of the fixed sleeves 16, 17 are formed with serrated surfaces which are forced into engagement by a nut 27. Specification 190,129 is referred to.

Title: Improvements in circular knitting machines of the superimposed needle cylinder type
Inventor: SAUNDERS ALFRED PERCY
IPC: D04B9/10
Filed: 1957-08-23
Abstract: 841,223. Knitting-machines. WILDT & CO. Ltd. Aug. 14, 1958 [Aug. 23, 1957], No. 26705/57. Class 74 (2). In a rotatable superposed cylinder machine, the feeding ends of interchangeable terry thread feeders 28, 29 move through the mouth of a circumferential, open-ended gap 23 in a fixed latch guard 21, between a non-feeding position on the outside of the latch guard (at which position the thread is taken by a cutter and trapper 31 or 32) and a feeding position at the inside of the latch guard. The gap is of such size and disposition that latch guarding functions are not interfered with in the normal direction of knitting; but, during reverse strokes of the machine a circumferentially slidable closer 24 closes the gap mouth, so that an unbroken latch guard inner face is presented to open frame needle latches. The inclined leading edge 24a of the closer also serves to guide an outgoing yarn into its trapper. The feeders 28, 29 are each so mounted that they can swing in both vertical and horizontal planes and are constrained to follow the desired paths by cam slots 49, 54 through which they pass. Both feeders and their cutters and trappers are operated, through linkages, from the main control drum 30. In addition, when knitting a half-round terry area, such as a high heel or a foot bottom, the feeder 29 and its cutter and trapper 32 are operated from a rotary cam unit 70 driven at appropriate times through a clutch controlled by the drum 30. The unit 70 comprises an outer cam 82 operating the yarn feeder and an inner cam 83 operating the cutter and trapper; and the yarn is taken in and out of action during each course, so that it is supplied to the heel and toe group of needles. During reciprocatory knitting, the operative terry feeder may oscillate within the gap 23 moving, at each stroke, in a direction against that of the needle cylinders; and the closer will be operated from a cam fixed to the top needle cylinder. The terry yarns are drawn over the tips 8e of terry instruments 8, each of which rocks about a fulcrum 8a in its trick in a cylindrical carrier secured within the top needle cylinder. The elevation of the instruments is determined by a cam race 10 acting on butts 8c, their tips are retracted by cams 13-16 acting on butts 8b; and presser levers and/or cams 17-20 project the tips by action on butts 8f-8i. The terry yarns T, T<SP>1</SP> may be of contrasting character and may be used to produce horizontal striping. A ground yarn G, G1, or G2 is fed in, under the bottom edge of the latch guard, from one of yarn guides 40, 41, 42 associated with conventional yarn changing, e.g. horizontal striping, mechanism incorporating yarn trappers and cutters 43 (not shown), 44, which are disposed before the stitch cam, whereas those 31, 32 are located just after the stitch cam.
