Title: Improvements in blading for gas and steam turbines
IPC: F01D5/30
Filed: 1927-11-03
Abstract: 280,221. B³chi, A. Nov. 6, 1926, [Convention date]. Blades for gas and steam turbines are fixed by employing at least one elastic fixing member so that when cold, they are firmly held and when hot, are not permanently deformed owing to the high stresses caused by expansion. Fig. 1 shows such a fixing means wherein the blade-root b has a slot d and the rotor c has clearance at f and below the bladeroot. The slots d may be cut horizontally. Instead of cutting slots in the blade-roots, separate spring packing pieces may be inserted, such as n, Fig. 6. The slots may be cut in the shoulders of the rotor, as in Fig. 5. Fig. 3 shows a portion of a rotor with blades a mounted in various ways. The first blade is provided with a packing piece made elastic by the slot d. The root of the next blade is slotted for elasticity and has a solid packing piece g of a resilient piece i. The next blade has a solid root and a resilient packing piece g. The last blade has a solid root a solid packing piece g and a resilient S- shaped packing piece k. The slots or resilient packing pieces may be arranged to permit freedom of expansion in three dimensions. The packing pieces and blade-roots have clearance at f for the expansion of the unresilient parts.

Abstract: 1,194,257. Electrical component assemblies. ROBERTSHAW CONTROLS CO. 26 June, 1967 [12 July, 1966], No. 29438/67. Heading H1R. [Also in Division E2] Relates to arrangements for mounting electrical component housings on an instrument panel, either individually or wherein a plurality of component modules housings are ganged together. In the flange mounting of a housing 10, 12 (Fig. 1) in a cut-out in a panel 54 (Fig. 3), flange plates 38 having flanges 40 are laid alongside the housing walls so that slots 46, 48 coincide with slots 20 in the said walls. Resilient U-clips 24 are then positioned so that bights 36 of each clip pass through a respective slot 46, 48 and hook around tangs 22 within the slots 20 (detailed in Fig. 2, not shown) thereby holding the flange plates and housing together. The assembly is then pressed through the cutout from the front of the panel until flanges 40 engage the panel surface as shown in Fig. 3. Figs. 5 and 6 (not shown) illustrate an arrangement wherein two housings are clipped to an intervening barrier plate (detailed in Fig. 4, not shown) the clips being disposed on opposite faces of the plate and resting, in grooves thereon, bights on the clips engaging the tangs on the housings sides. Attached to the barrier plate is a U-shaped resilient clamp. To mount the ganged housings on the panel, the assembly is pressed into a cut-out in the panel until the rear surface of a lip on the barrier plate abuts the panel. The arms of the clamp flex inwardly during insertion, and after insertion spring outwardly and retain the ganged assembly on the panel. A combination of flange and barrier plate mounting arrangements may be used.

The apparatus may be operable as a viewer or projector for the processed result. As described in connection with drawings a camera generally similar to that of Specification 784,076 with a passage 58 into which an opaque cover sheet 54 of the film unit 46 is projected during insertion of the latter through passage 44 into the camera, to leave sensitive surface 50 ready for exposure between .guide walls 28, 30, and with mechanism generally indicated at 90 for operation of the shutter by the film unit; has pressure element 70 partly supported on ramp portion 82 of a plate 80 which latter has tabs 84 to be engaged by the film unit 46 during the latter part of its movement and so move plate 80 leftward and release pressure element 70 into inoperative position for withdrawal, after exposure, of the film unit 46. End 86 of plate 80 projected out of the camera by the leftward movement is used to return the plate to its former position before insertion of another film unit into the camera. To spread the processing liquid after exposure another form of camera (Fig. 5, not shown), has an end portion of the plate 80 constituting a ramp in the reverse direction of the ramp 82, whereby pressure element 70 is raised at the latter part of movement of the film unit 46, to be operative only on withdrawal of the film unit. Specification 684,592 also is referred to.
