Abstract: A device for continuously forming a heat exchanger that has a helically wound fin tube coil formed by a plurality of wraps includes a rotationally driven mandrel with a central axis and a plurality of forming corners equiangularly disposed about and displaced from the central axis. The rotation of the mandrel is about the central axis in order to wind the fin tube coils onto the mandrel. A forming block is operably rotationally coupled to the mandrel and rotates with the mandrel. The forming block is also slideably engaged with the mandrel for axial translation a selected distance with respect to the mandrel. The forming block guides the winding of the fin tub coils onto the mandrel. An actuator is operably coupled to the forming block and causes the axial translation of the forming block.
Abstract: A tuck label construction which is simple and inexpensive to manufacture, is capable of being printed by a wide variety of conventional automated printing devices, and which can be printed with automated control systems such as bar codes is provided. In one form, the label includes a face ply having first and second major surfaces and a liner ply having first and second major surfaces. The first surface of the face ply includes an adhesive thereon which is adhered to the first surface of the liner ply, and the first surface of the liner ply contains a release agent thereon. Each of the face and liner plies includes a pair of end panels having center panels therebetween, with the end panels on the face ply being defined by lines of weakness between the end panels and the center panel on the face ply, and the end panels on the liner ply being Separated from the center panel on the liner ply.
Abstract: A method of operating a pre-mix power burner assembly. The method comprises the steps of: using a fan to supply and control combustion; mixing fuel gas and primary air together; introducing the mixture into secondary air in a combustion zone; and relieving pressure on the exterior of the fan near the fan shaft to the interior of the fan.
Abstract: A three piece rail car truck has a pair of side frames, a pair of wheelsets and a roller bearing adapter seated on each end of each wheelset. Each side frame has pedestal jaws formed and adapted to seat upon each roller bearing adapter. The improvement comprises a stabilizer bar connected between each roller bearing adapter and an adjacent portion of a side frame, with the stabilizer bars resisting unsquaring relative movement between the wheelsets and side frames.
Abstract: A sanitary water valve having control elements consisting of at least two discs. The first disc is arranged immovably and constitutes the valve seat disc and the second disc, which constitutes the control disc, is arranged movably on the first disc and has a surface conduit for deflection functions which can simultaneously be made to overlap the inflow apertures and outflow aperture on the first disc. The second disc includes one or more depressions which substantially reduce the actuation forces required to open the water valve and as a result, operating efficiency is considerably enhanced.
Abstract: A shower head with a spray plate mounted on the housing has water passage openings and a further plate made of elastic material which has openings coaxial to the water passage openings. The further plate is fitted over the outside of the spray plate which presses against it. Nozzle projections with exit openings are formed coaxial with respect to the openings which have a smaller diameter than the water passage openings.
Abstract: A valve device is provided, the base of which includes a lower valve seat of a reflux and aerating valve, which is inserted into a hollow space located above the taps. The hollow space is sealed at the bottom and open at the top and/or side. If the valve device has any sealing flaws, the leaking water is collected, and air flows into the valve device via the hollow space if the pressure in the main water supply drops. If any water seeps out of the valve device due to sealing flaws in the valve, water flows from the lower valve seat to the hollow space of the separator wherein it collects and flows out through the opening in the separator. As a result, leakages in the fittings can be detected easily and quickly.
Abstract: In order to adapt a base body for sanitary fittings to a selected cartridge (10, 30), the base body (1) is linked to a cap (2, 32) provided with water through channels (3, 4, 5) whose ends at the side of the cap (2, 32) facing the cartridge (10, 30) are sized and shaped to correspond to the water inlets and outlets of the cartridge (10, 30).
Abstract: A three-dimensional substrate material for use in constructing battery electrodes comprises a sintered matrix material selected from the group consisting of reticulated metal foams, conductive fibers and metal powder compacts, and a porous covering layer of a polymeric mesh material, flexible metal screen or metal fibers, bonded to at least one surface of the matrix material to retain the sintered matrix material substantially within the planar surface of the surface of matrix material during spiral-wounding of the chemically loaded matrix material.

Abstract: There is disclosed a sealing device (7) comprising an elongate sealing portion (8) secured substantially along its length to an adhesive means (10) having an outer adhesive surface (11) remote from the sealing portion. The device further comprises a plurality of protruding members (12) positioned at predetermined intervals along its length and having a protruding end (15) protruding from the outer adhesive surface (11) of the adhesive means (10). The protruding members (12) comprise a flat portion (13) of small thickness opposite the protruding end (15). Also disclosed is a sealable body in which the sealing device is used and methods for forming the sealing device.

Abstract: The invention relates to novel membranes, formed from perovskitic or multi-phase structures, with a chemically active coating which demonstrate exceptionally high rates of fluid flux. One application is the separation of oxygen from oxygen-containing feeds at elevated temperatures. The membranes are conductors of oxygen ions and electrons, and are substantially stable in air over the temperature range of 25.degree. C. to the operating temperature of the membrane.
Abstract: A high side co-rotational scroll compressor has lubricant sumps in both the discharge and suction pressure portions of its hermetic shell as well as a pressure biasing arrangement by which the scroll members are urged together in operation to minimize internal leakage. Lubrication of the bearing in which the driven scroll member rotates as well as to the bearing in which the idler scroll member rotates, both of which are located in the suction pressure portion of the shell, is provided for. Additionally, embodiments are taught by which the interface between the tips of the wraps of each scroll member and the end plate of the opposing scroll member are lubricated and by which the seal in the axial pressure biasing arrangement is lubricated and/or shielded from debris having the potential to damage it.
Abstract: In an arrangement for supplying steel from a base outlet of an intermediate vessel (2) in a continuous casting installation, the intermediate vessel (2) is provided with an outlet block (3). Beneath the outlet block (3) there is arranged a first change-over part (6) which is movable transversely to the discharge direction (4) and can be pushed out of the casting position by a moving arrangement (30) and a second change-over part (38). An arrangement of this type is to be improved in such a way that the casting nozzle body has a longer service life and is cheaper to produce. Furthermore, security on the casting platform is to be improved during interruptions in casting, the extraction speeds during continuous casting are to be altered and the positional accuracy of the outlet block is to be increased. For this purpose, the change-over part (6) is made up of a holding frame (12) and a casting nozzle body (11). The holding frame (12) is guided and positioned on guide strips (14) in guide rails (7, 7').
