Title: Improvements in or relating to guide vanes for axial-flow turbines and compressors
IPC: F01D9/04
Filed: 1946-04-05
Abstract: 611,326. Axial-flow turbines and compressors. LOMBARD, A. A., and MORLEY, F. W. W. April 5, 1946, No. 10630. [Classes 110 (i) and 110 (iii)] In an axial-flow turbine or compressor of the type in which the guide vanes are mounted between inner and outer rings, each vane is secured to only one such ring at one part of the vane-end and is loosely supported by the other ring. Each vane is formed with circumferentially extending platforms 7, 8 which are of parallelogrammic or rectangular shape. The vane is located on rings 9, 10 by means of splines 17, 18, Figs. 3 and 4, which engage helically-disposed slots 11. The central part of each spline is machined away as at 19 to reduce any tendency to bind. A foot 13 projecting from one end of the spline 17 engages in a recess 14 in ring 9 and is loosely retained by an overlying flange 16 of the nozzle box 15. The platform 8 may engage an abutment 20. In a modified construction, Fig. 2, the splines 17, 18 are dispensed with, and the internal surfaces of the platforms 7, 8 are flush with the lands 12.

Title: Improvements in or relating to locks
IPC: E05B67/02
Filed: 1944-06-02
Abstract: 587,000. Lock cases; padlocks. STEVENS, A. H. (Master Lock Co.). June 2, 1944, No. 10642. [Class 44] [Also in Group XXII] In a lock, particularly a padlock, having a laminated casing formed of superposed plates, with apertures which register to provide the requisite internal cavities and projections, one of the plates is cut away near one edge to provide a spaced pair of webs which allow the intermediate marginal portion of the plate to be displaced parallel to the plane of the plate, to carry said marginal portion towards a cavityforming opening in the plate. The external edge of the displaceable marginal portion is bulged to stand proud of the edges of adjacent plates when first assembled, being subsequently forced into flush position to effect the abovementioned displacement. As described, the inner edge of the marginal portion has an integral tongue which, after displacement, acts as a stop or retaining member. In the padlock shown top and bottom plates 1, 2 and intermediate plates 3 together with plate 4 of the present invention are assembled and permanently connected by rivets 16. Plate 4 is cut away to provide a pair of webs 4h adjacent to rivets 16, the outer edge of the intermediate portion 4b bulging to project beyond adjacent plate edges, the inner edge carrying a tongue 4d the free end 4a of which is just clear of the cylindrical cavity provided to receive the longer limb 7 of the shackle 5. A shackle-ejecting spring 15 and the shackle are placed in position and held whilst the bulge 4b is forced inwards in a press. The tongue end 4a is thus moved into engagement with a flat 14 on shackle limb 7. The inner end of the flat ends in an annular groove 8 bounded on its lower side by a head 9. As shown, limb 7 has opposed grooves 11 in which the limbs of a spring locking member 12, assembled with the plates, engage when the shackle is pressed home. The end of a key 13 engages between these links and separates them when the key is turned, spring 15 ejecting the shackle until arrested by engagement of tongue end 4a with the shoulder provided by head 9, in which position the tongue registers with groove 8 so that the shackle may be rotated to swing its limb 6 clear of the casing. Modifications may be made in the disposition of the bulge, and shape of tongue. Fig. 8 shows one such modification in which two opposed bulges 43b are provided to displace corresponding tongues 43a inwardly.

IPC: G03B17/42
Abstract: 107,881. Guignard, E. M. F. Sept. 26, 1916. Magazine hand cameras with connected action between shutter and changing-mechanism. - A slide 19, Fig. 3, connected to a flexible cable is caused to move, when the film-winding means is operated, by the action of a ratchet 16, which is mounted on the film-roller, upon a pawl 17 carried by the slide 19. In the arrangement shown in Fig. 1, the cable 21, upon operation of the film-winding means, rocks the pivoted lever 23 and so withdraws a locking-lever 27 from below the shutter lever 12. In the modification shown in Fig. 4, the cable returns the lever 23<a> into position with the inner end immediately beneath the lever 12<a>. In the modification shown in Fig. 5, the shutter is operated by means of the member 12<b> to which the cable operating the shutter is connected. The cable connected to the film-winding means terminates in a member which will remain in the lowered position when the shutter has been operated until the filmwinding means is operated and so restores it to the position shown through the movement of the slide 19.

Title: Improvements in devices for drawing off welts on flat knitting machines

Filed: 1940-06-29
Abstract: 542,286. Knitting. SCHUBERT & SALZER MASCHINENFABRIK AKT.-GES. June 29, 1940, No. 11069. Convention date, June 29, 1939. [Class 74 (ii)] Relates to devices for drawing the welts off the needles of flat knitting-machines. The welts having been inserted in welt bars 8, endless chains 6 carrying hooks 7 are started moving and take the bars 8 along with them until the position shown in Fig. 2 is reached; when the bars 8 engage pincer like holders 11, 14 on the fabric roller 4 and disengage from the hooks 7. The welted fabrics then start to wind on the fabric rollers 4. A modified form of hook 20, pivoted to the chain and subject to the action of .springs 21 is used when it is desired to obtain shorter welts. The hooks 20 are shaped to the curvature of the fabric rollers. Differences in tension occurring in the fabric during the drawing off of the welt bars are compensated by a spring arrangement in the fabric roller 4 itself. In each division of the machine annular members 22 are fixed upon the shaft 1 of the fabric roller by means of screws 23. The fabric rollers 4 are mounted and are freely rotatable on sleeves 24 provided on the members 22. Metal caps 9 provided at both ends of the rollers 4 have annular recesses 25 into which extend pins 26,27 on the members 22 and a cross-pin 28 on the cap 9. The recess 25 also carries a compression spring 29, which abuts on pins 26, 28 and tends to hold pins 27, 28 in driving engagement. When, however, the tension rises sufficiently the roller 4 can yield temporarily, the pin 28 moving away from pin 27 as shown.
