Abstract: ABSTRACT           The invention relates to an electromagnetic device and specifically to a low voltage transformer relay and a ferromagnetic core used therein.  The electro-magnetic device has opposed pole faces defining a gap area, a source of operating flux for establishing a magnetic field in the gap, a source of latching flux for retaining an armature in contact with either of the pole faces, and a source of counter flux proximate the gap. The source of counter flux proximate the gap operates to confine the operating flux to within the gap.  The source of latching flux utilizes a flux return bracket for conducting flux between the source of latching flux and the armature.  Further, the source of latching flux has a surface area A perpendicular to the flux path and a length L along the flux path such that the factor L/A is less than 1 so that a path of low reluctance is provided for a portion of the operating flux.  Further, the operating legs of the ferromagnetic core are constructed from tapered first and second leg elements which have continuous tapered interfaces adapted to cooperatively mate forming low reluctance first and second legs.  Such an electromagnetic device may be utilized with advantage as a low voltage transformer relay in order to control an electrical load by a plurality of low voltage switches located in various locations.

Abstract: STEEL ROD ROLLING PROCESS, PRODUCT AND APPARATUS            ABSTRACT         A process for rolling steel rod is provided whereby rolling rod at delivery speeds in excess of 15,000 fpm and cooling same after laying it in spread-out ring form on a conveyor is made feasible with less risk of cobbles and improved rod quality especially in the medium to high carbon content range by entering the rod after rolling into the laying head and thereafter cooling same non-uniformly through a grain size growing phase and a transformation phase with the non-uniformity of cooling rate during the transformation phase being kept in substan-tially inverse proportion to the differences in effective grain size established in the first phase. In addition a very long cool-ing conveyor which is necessitated by such delivery speeds (not only for high carbon steels but also low carbon and low alloy steels) is provided without requiring additional horizontal space, by arranging the conveyor in a multiplicity of tiers, spaced vertically, running in opposite directions, and being provided with means for transferring the rings from one tier to the next.          Cobbles on the conveyor at high delivery speeds are minimized by coiling with 1/2" spacing, and by reforming means adapted for high speed delivery of rings from the conveyor onto an upwardly sloping mandrel surface, or into a curved chute which stacks the rings on their sides.  An intermittent reheat method is employed for processing rod where slow cooling and/or heat treatment at a steady temperature is required.

Abstract: PIPELINE LEAK DETECTION METHOD               AND CONTROL DEVICE THEREFORE     A B S T R A C T        For sealing a pipeline at selective locations in order to perform leak tests, a pipe-line packer assembly capable of internal travel within the pipeline can be moved to and stopped at selected locations and the packer inflated against the interior pipe walls to prevent further move-ment of the unit, and to provide a seal so that the pipeline may be subjected to internal high pressures to detect leaks.  According to the invention, a control device for such unit comprises a gamma ray detector and signal processor receiving the electrical analogue signal from the gamma ray detector.  An energizing signal from the signal processor actuates a stepping switch which provides "inflate" and "deflate" energization of the packer, and is kept in "off" condition while the packer is inoperative as in transit within the pipeline.  A radiation source on the surface or selectively inserted into a bore hole near the pipeline pro-vides a stimulus for the gamma ray detector which controls the operation of the stepping switch.

Abstract: APPARATUS FOR PROVIDING IMPROVED CHARACTERISTICS OF A BROAD AREA ELECTRON BEAM         ABSTRACT OF THE DISCLOSURE An electron beam device having a vacuum chamber in which an electron beam generator generates a directed stream of electrons.  An electron beam window comprising a foil which seals the vacuum chamber is in the path of the stream of electrons and permits passage of the stream of electrons into a working region exterior of the chamber and adjacent the electron beam window.  An electrode is positioned closely adjacent the foil and a second electrode is spaced from the foil to form an elongated working or, in the case of a laser, a lasing region between them.  The electrodes are maintained at a high electrical potential which, along with the electron beam, molecularly excites a gaseous working medium between the electrodes.  The in-cluded angle of electrons passing through and scattered by the foil is limited and the electron beam confined to a desired region by an external shield or bezel overlying the foil.  The bezel is provided with a series of openings which may be in the form of holes or slots of predetermined depth, size and spacing one from another to provide the electrons emerging from the foil with a desired included angle of emergence while maintaining losses at a minimum.

Abstract: ABSTRACT OF THE DISCLOSURE     According to the present invention, a new cold working metal process is disclosed for the formation of metal pipe union components, which includes blanks for so called gas meter swivels, which are actually pipe unions components with a slight adaptation.  Both male and female components are made by the process.  The process cold works a metal elongated hollow open ended blank to deform an unsupported circumferential portion of the blank wall into a predetermined shape.  The steps of the process comprise supporting portions of the blank wall exterior and interior in a manner to define a shaping section of the predetermined shape in the area of the unsupported wall portion; applying a compressive load on the blank ends of sufficient force to exceed the compressive yield strength of the metal blank thereby deforming the unsupported wall portions to cause the deforming metal to flow into the shaping section to provide said predetermined shape.  Pipe connectors produced by this process are inexpensive, less subject to material defects and, therefore, more reliable in the field.
