Abstract: A resistance heating element support for vacuum electric furnaces is described for use with such furnaces having a gas plenum chamber and for other vacuum electric furnaces having the support in spaced relation to the outer wall of the furnace, the support being removably carried in a tube extending across the plenum chamber or in an interior reflective shield carried on a supporting ring, the support being normally in locked position but being turnable through an angle for release and removal.

Abstract: Apparatus for processing photographic materials is disclosed and more specifically equipment for turnaround during processing of an elongated web of photographic material at the midportion of a processing operation, the web being guided in part by inner and outer rollers but having vibrating guides interposed between pairs of rollers, the guides being oscillated by the drive for the rollers. Various types of oscillating mechanism for the guides is shown.

Abstract: A transport roller system is provided for use in photographic film treating tanks employed for developing, fixing, washing and the like, in which on each side of the rack frame plates, a central driving cluster gear is provided on a roller shaft of a central vertically disposed roller system with driven cluster gears on roller shafts on each of roller systems on each side of the central vertical roller system to provide for downward and upward movement of a film strip, with provisions including pairs of actuating drive gears on alternate central horizontal roller shafts, the pairs of actuating drive gears on the alternate shafts on the outside of each of the rack frame plates comprising a driving gear connected to its respective shaft and an idler gear each meshing with contiguous gears, the pairs of gears having larger pitch circles than the cluster gears and having pitch diameters corresponding to the center to center distance between alternating shafts of the central vertically disposed roller system, wher

Abstract: Force transferring elements are disclosed which include a metal or plastic hub deep drawn or elongated with a flange extending therefrom and functioning as a force transferring element. The hub and flange may be of one piece with the flange having blades extending outwardly from the hub, the hub around its circumference being provided with a plurality of indented portions or corrugations to provide a spring action for engagement with a shaft. In another form of the invention two similar pieces are utilized each with a deep drawn or elongated hub and having outer rims which together receive a V-belt or the like. The elements may be connected to a shaft for input to the shaft, or may be carried on the shaft as energy converting or driving members.

Abstract: A machine is provided for removing the entire length of a tube from a heat exchanger or the like, after the expanded end portions thereof have been extracted a short distance from the outer face of the tube sheet, utilizing a power driven chain conveyor with toothed links which engage and grip the outside of the tube, wedging the tube into a coacting trough or shoe which can be applied to the tube at a selected location along its length and draws the tube through the machine and clear of the exchanger.

Abstract: An expansible caulking material in strip form is disclosed suitable for use in sealing joints between vertical panels, and packing wide expansion joints occurring in decks of parking garages, bridges, airport runways and the like, with a shortened expansion time particularly for use in cold locations where the expansibility by reason of the adhesive impregnant would be unduly delayed. The caulking material comprises compressed and expansible strips of open cell plastic foam with one or more wires or strips therewith with the foam normally retained in compressed condition until ready for use, and in which an electric current is applied to the ends of the wires or strips to supply heat to speed up the expansion.

Abstract: A floating solar heater for swimming pools is disclosed which includes a top cover, a vertical outer side wall with inclined inner side wall segments connected thereto, an outside rim and a bottom wall.
