Abstract: A corrosion resistant tubular system is formed of a length of pipe in which each of the opposed ends terminate in a reduced external diameter integral tubular lip portion and, spaced from the lip portion, increased diameter external threads compared to the tubular lip portion, the lip portion having an external circumferential frusto-conical surface and a tubular coupling having internal threads adjacent each of the ends thereof and having, spaced inwardly from each of the internal threads a reduced internal diameter circumferential sealing surface that is tapered in a frusto-conical shape, the interior of the tubing and the coupling being formed of corrosion resistant metal alloy. When assembled a telescopic mating relationship is established between the external conical surface of the pipe and the internal conical surface of the coupling.

Abstract: A method of manufacturing clad metal plate products by assembling in a stacked array a bottom base plate, a first cladding plate, a second cladding plate and a top base plate, with a separator compound layer between the first and second cladding plates. The peripheral dimensions of the cladding plates being less than the peripheral dimensions of the base plates. A metal rail is welded between the base plates and circumferentially of the cladding plates to form an assembly having a closed environment encompassing the cladding plates. Substantially all water and oxygen are removed from the closed environment. The assembly is then heated to an initial temperature of at least about 1850.degree. F. and, while heated, is rolled or hydraulically pressed to cause the first cladding plate to bond to the bottom base plate and the second cladding plate to bond to the top base plate. Separating the assembly at the separator compound layer provides a first and a second clad plate.

Abstract: A cover for battery terminals includes a cap arrangement that may be placed over a battery terminal and a standard cable connector to seal and protect against corrosion. In a first form, the cap includes hinged base sections and a cover section. The hinged base sections include semi-circular recesses that close about the terminal below the connector. The cover section is received over the terminal connector and upright walls of the base section. A first seal is positioned between the cap and the battery case, sealing the cap to the case. A second seal fits between the cable and the cap to complete the sealed enclosure about the terminal and connector. In a second preferred embodiment, the cap includes top and side walls with cable passages. In this embodiment, a surface is formed on the battery case for engagement with the cap to form a first seal about the terminal and connector.

Abstract: A cover for battery terminals includes a base plate and cap arrangement that, together with flexible seals, may be placed over a battery terminal and an attached connector to seal and protect the terminal and connector against corrosion. The base plate includes two base sections that are connected by an integral hinge. Each section includes a semi-circular recess that closes about the terminal below the connector when the two sections are moved together to a closed condition. A first flexible seal is positioned over the terminal post prior to placement of the base. The base may then be placed over the terminal and pressed onto the seal. The seal will deform and fill any voids between the terminal and the cover base. The cap may then be placed over the base, enclosing the terminal and connector. Interfitting walls of the cap and base form an enclosure seal about the terminal and connector. Matching cable receiving recesses are provided in the walls of the base and cap.

Abstract: A method of manufacturing an externally clad tubular product employing a tubular host such as steel, including the steps of plating the external surface of the tubular host with a low melting point bonding metal alloy, assembling a tubular clad member, such as of nickel base alloy, over the plated tubular host, circumferentially welding one end of the cladding member to one end of the host member and welding the other ends in such a manner as to incorporate a metallic gas reservoir, thus forming a subassembly.

Abstract: Apparatus and method for maintaining steady state compact toroidal plasmas. A compact toroidal plasma is formed by a magnetized coaxial plasma gun and held in close proximity to the gun electrodes by applied magnetic fields or magnetic fields produced by image currents in conducting walls. Voltage supply means maintains a constant potential across the electrodes producing an increasing magnetic helicity which drives the plasma away from a minimum energy state. The plasma globally relaxes to a new minimum energy state, conserving helicity according to Taylor's relaxation hypothesis, and injecting net helicity into the core of the compact toroidal plasma. Controlling the voltage so as to inject net helicity at a predetermined rate based on dissipative processes maintains or increases the compact toroidal plasma in a time averaged steady state mode.

Abstract: A photographic exposure control for sensing and electrically processing illumination reflected from a moving document. An opto-photoelectric pickup accepts reflected illumination having a selected spectral characteristic. Electronic analog logic; (1) samples and holds the equivalent electrical magnitude of the reflected illumination, (2) provides an electrical timing interval that is the reciprocal of the electrical magnitude, (3) arranges automatically for constant exposure of the film through an adjustable electrical ramp generator, and (4) generates an "exposure stop" signal in a comparator that receives the ramp and the reciprocal timing information. The control signal thereby formulated typically accurately actuates a translational type shutter through a stepper motor to maintain a constant density of the background of images on microfilm for successive documents regardless of the background reflectivity thereof.
