Abstract: A form for constructing a refractory roof for an electric arc furnace having a provision for selectively changing the electrode opening pattern and also forming a roof of different diameters.

Abstract: This invention relates to a process for the application of organic materials, such as powders, to hot dip or electroplated galvanized metal which provides a finished material with a higher level of corrosion resistance than that obtained from organic coatings on mild or black steel. Because of the natural corrosion protection properties of the zinc cladding of galvanized metal, no additional passivation of the substrate is necessary as is required with existing processes on mild or black steel. Also, the invention relates to the hot dip or electroplated galvanized metal which has been pretreated by the process of this invention prior to application of an organic powder coating. Hot dip or electroplated galvanized metal treated by this process leads to a uniform coating which is virtually impervious to acid, basic and salt solutions, and which will not scratch or flake off on impact.

Abstract: A rotundity gage for measuring the roundness of a wheel tread of a railway wheel. The gage includes a measuring device and is adjustable so as to be capable of measuring different size wheels.

Abstract: A railway coupler yoke assembly is provided. A yoke, draft gear and follower are assembled as a unit assembly and maintained as such by the installation of bands at various locations about the assembly.

Abstract: A wire rope is provided having a central core strand about which are wound outer strands. Spacer strands are present in the gaps between such core strand and outer strands to assume the uniformity of such gaps. A coating, usually of a suitable thermoplastic, is extruded into such rope to provide a spacer between such core and such outer strands, and between adjacent outer strands.

Abstract: A filter apparatus for removing suspended matter from a suspension including a tank for receiving the contaminated liquid and a filtrate chamber. A perforate wall of the filtrate supports an endless and reusable filter media. The filter media is in the form of a closed loop having a run of the loop located outside and below the tank for the convenience of removing suspended solid collected on the media. The media is displaced along the length of the perforate wall to provide a solids free filter area by a movable conveyor. The conveyor serves to displace the media and hold the marginal edges in sealing engagement with edges of the perforate plate to prevent the contaminated liquid from bypassing the filter area.

Abstract: Oil-water mixtures are by-products of a number of known commercial activities such as crude oil production and power plant operation. Disposition of such mixtures in most all cases is prohibited by environmental regulation. Disposition may be effected, however, after separation of the oil from the water. This separation may be accomplished in a deepbed type filter. Where the oil in the water is unusually viscous or has a waxy, tar-like, or sticky consistency, for example, rejuvenation of the filter bed is enhanced by the addition of a small amount of a solvating liquid to the oil-water mixture before filtering.

Abstract: A restrained mechanical pipe joint including a spigot end of one pipe seated in a socket end of a second end or a fitting. The joint includes a single tightening means and a restraining ring formed to permit limited misalignment of the longitudinal axes of the spigot and socket pipe ends.

Abstract: The present invention provides a method of preventing the segregation of powders of different specific gravities in a metal powder composition. The powder metal is admixed with the powders of lesser specific gravities, and furfuryl alcohol is added at the same time. While mixing, an acid is added to react with the furfuryl alcohol to convert the alcohol to a solid resin film on the powder metal particles. The powders of lesser specific gravities are bonded to the metal powder particles by the resin, and segregation of the metal powder and the lighter powders is eliminated.

Abstract: A locating pin having a generally cylindrical, threaded lower portion and an axially aligned, nonthreaded upper portion is provided. The threaded lower portion has at least one vertical slot in which is located a locking bar. The locking bar has a flat lower portion that permits the pin to be threaded into a receiving opening. The locking bar has a wedge shaped upper portion that is driven down into the opening to retain the pin therein. The upper portion of the pin extends from the opening to provide a locating pin.

Abstract: This invention relates to a post indicating valve assembly and more specifically to an orienting means formed at the end of an operating shaft to provide a reference in determining the closure member positions.
