Thereby eliminating the need for sucker rod strings in pumped wells. A partition located between two coaxial hollow cylinders for keeping the production fluid separate from the hydraulic fluid.
Abstract: Directed to a transportable rack for handling bakery goods such as bread which is made of moldable plastic, has a base trolley on which are mounted modular stackable shelf units having longitudinally extending parallel side rails adapted to hold bakery goods for transport, and separating members outboard each shelf unit which provide vertical separation between the shelves and transmit the weight of the shelf and its contents downward so that each shelf is light, with the separating members forming a vertical load-bearing and bracing column on each side of the rack.
Abstract: The invention relates to a method and apparatus for relining bores such as oil wells, using multiple layers of spiral wrapped, resilient lining material which expands to form a continuous liner for the bore.
Abstract: The invention contemplates a thermomechanical process applicable to beryllium copper alloys consisting essentially of about 0.2 wt % to about 0.7 wt % beryllium; from about 1.0 wt % to about 3.5 wt % nickel and cobalt in the aggregate, where nickel comprises at least about 1.0 wt %; up to about 1.0 wt % zirconium; up to about 0.005 wt % lead; up to about 0.1 wt % magnesium; up to about 1.5 wt % silver; up to about 0.5 wt % incidental impurities including lead; and the balance essentially copper; which process comprises solution annealing said alloy at a temperature of at least about 90% of the incipient melting point of the alloy expressed in degrees Fahrenheit, cold working the solution treated alloy to reduce the section thickness thereof at least about 60% or much more, and then aging the alloy to produce therein an improved combination of properties including strength, ductility, formability and conductivity.
Abstract: This invention is directed to the treatment of copper beryllium alloys, and to articles and parts made therefrom, containing special small amounts of beryllium and nickel, e.g., about 0.05% to about 0.5% beryllium and about 0.05% to about 1% nickel where cobalt may be substituted for up to about one-half of said nickel content at a substitution ratio of about 1 part by weight cobalt for about 2 parts by weight nickel, which imparts to these alloys a superior combination of stress relaxation resistance, formability, ductility, conductivity and strength by the process of solution annealing, cold working at least about 50% or at least about 70% or 90% or more and age hardening.

Abstract: A covered electrode for welding chloride resistant stainless steel of the type containing about 0.04% carbon, 20% chromium, 24% nickel, 5% molybdenum, and balance iron. The covered electrode provides the capability for producing substantially defect-free stainless steel weld deposits that offer excellent resistance to crevice corrosion, as well as general corrosion in chloride containing environments.
Abstract: A method for reducing passivation of a lithium anode used in a cell having a liquid thionyl chloride cathode is disclosed, characterized in that the anode is coated before the assembly of the cell with a solution of an alkyl 2-cyanoacrylate, a solvent, and lithium perchlorate.
Abstract: The metal content of nickel-cobalt mixed sulfide slurries is recovered by atmospheric oxidation leaching, thereafter removing dissolved copper by metathesis with further mixed sulfide feed, treating the filtrate after liquid-solids separation with ammonia to selectively precipitate cobalt, separating the cobalt precipitate and working up the resulting filtrate to recover nickel.
Abstract: An unsupported particulate catalyst especially useful for methanation reactions is prepared by a method comprising fluid-bed roasting agglomerates of nickel sulfide to form a particulate precursor material which can be reduced to composite particles consisting essentially of a nickel-oxide core with a then coherent adherent layer of nickel thereon, the reduced particles being characterized at the surface by the presence of microcapillary pores interconnecting with each other and the outer surface of the particles.
Abstract: This invention is concerned with a process for dissolving oxidic trivalent cobalt compounds in hydrochloric acid while avoiding the generation of chlorine. It includes the following steps (a) slurrying in water the trivalent cobalt compound to be dissolved and (b) treating the resulting slurry with a reduction agent from the group consisting of methanol, formaldehyde and formic acid and with hydrochloric acid. The contact of the hydrochloric acid with the slurry should occur in the presence of the reducing agent. The rate of acid addition should be controlled to maintain the slurry at a pH above 1.

Abstract: A composite electrode having a structural electrode member with at least a portion of one surface of the electrode member constructed from a continuous matrix of an anodically passivatable metal infiltrated by a metal capable of forming an electroconductive oxide and having the infiltrating metal at the electrode surface oxidized such that an electric current path is provided through the oxidized surface of the matrix metal. In one embodiment the matrix metal is an electrochemical valve metal, e.g., titanium and the infiltrating metal is lead. Applications for the composite electrode include battery grids and electrochemical processing electrodes.
