Abstract: A method by which multiple strands of slit metal material are wound upon the rotating drum of a recoiler.  Frictional contact between the recoiler drum and strands cause the strands to be coiled about the drum with relative movement between the recoiler drum and the separate coils of strands occurring to accommodate the varying thicknesses of the individual strands so that the strands are wound upon the drum at substantially the same linear speed.

Abstract: ABSTRACT OF THE DISCLOSURE            A heat exchanger in the form of a heat radiating or absorbing panel is disclosed, which consists of an aluminum panel having a copper tube secured thereto in heat exchange relationship.  The panel has at least one pair of parallel, spaced, retainer legs which have angularly inwardly extending flanges.  A copper tube of circular cross section is laid into the channel formed by said retainer legs, and is then squashed by means of a die into a generally oval cross section which will be confined within the retainer legs.  While so confined, fluid under pressure may be introduced into the tube to expand it into intimate contact with the panel, the retainer legs and the flanges.  The assembly may then be heated during the expanding step to a temperature somewhat above the expected operating temperature of the assembly, to prevent loosening of the intimate contact between the tube and panel, which have different coefficients of expansion.          Provision may be made to cause flow through the tube to be turbulent or swirling.   Alternatively, the introduction of fluid under pressure, and the heating of the assembly, may be omitted, and the sum of the inside surface of the back of the panel between the flanges, the inside surfaces of the flanges, and the underside of the die between the flanges, may be made equal to the outside circumference of the tube.          The exposed surface of the panel may be configured to increase its area and to provide good exposure over a wide range of angles of incidence.  The heat exchange relationship between the tube and panel may be enhanced by interposing a thin layer of a synthetic resin therebetween; and the resin may have powdered metal entrained therein.  If dimensional relationships alone are relied upon to provide intimate contact between the tube and panel, a mastic-like material in a thin film may be applied to the interface between the tube and panel to improve heat transfer and seal out moisture.

Abstract: ABSTRACT OF THE DISCLOSURE           Improved apparatus and methods are provided for conducting drill stem and production testing operations. A bypass sub removably receives a wireline tool in sealing engagement within a bypass sub bore, with the bypass sub including bypass passage means and selectively actuable port closure means to permit fluid from below the bypass sub to flow into conduit means above the bypass sub when the wire-line tool is seated and secured in the bypass sub.  In one embodiment, the means for selectively actuating the port closure means is a motorized shifter means incorporated in the wireline tool.  The wireline tool carries selected sensor devices for sensing earth formation characteristics.  Improved and unique means are provided for securing the wireline tool in the bypass sub and for selectively engaging the motorized shifter apparatus with the port closure means.  In addition, unique "fail safe" means are provided to ensure that the wireline tool and the bypass sub can be effectively removed from the well even in case of a malfunction of the motorized shifter means.

Abstract: Abstract of the Disclosure A mechanical shaft seal for sealing the space between a stationary element and a rotating element in order to separate an inner pressure medium space from an external space, preferably the atmosphere.  The seal comprises a sealing ring mounted on one of the elements and a counter ring mounted on the other of the elements.  The sealing ring and the counter-ring are provided with annular sealing fluid surfaces pressed against each other by means of the pressure of the pressure medium.  An intermediate space for a sealing fluid is limited by one of the elements, the sealing ring and said slide surfaces.  An annular piston is provided on said sealing ring in order to press the sealing ring in a direction closing said slide surfaces and thereby to increase the closing force subjected by the sealing fluid on said slide surfaces.  In this way the pressure of the sealing fluid is independent of the pressure of the pressure medium and the slide surfaces are always subjected to a closing action greater than the opening action irrespective of the pressure of the sealing fluid.

Abstract: IGNITION DISTRIBUTORS FOR INTERNAL        COMBUSTION ENGINES               ABSTRACT         A breakerless distributor for an internal combustion engine comprises a base, a shaft adapted to be driven by an engine and extending within the base, a rotary member rotatable by the shaft, an electronic means cooperating with the rotary member to produce timing pulses. According to one feature of the invention, the electronic means is in the form of a transmitter and sensor unit removably secured in an aperture in the base, the aperture being so positioned and dimensioned that the unit can be removed from the base without removal of the shaft or rotary member from the base.          According to a further feature, centrifugal means in the form of a pair of weights is interposed between the shaft and the rotary member to advance the rotary member relative to the shaft as the shaft speed increases.   Each weight is eccentrically mounted on a respective pivot on top of the rotary member, and a rotor assembly having a central input terminal and spaced peripheral output terminals is secured to rotate with the rotary member by means of a pair of screws each received in a screw threaded bore of a respective pivot thus providing a construction which is simple and cheap to manufacture and easily accessible for servicing.

Abstract: CONTROLLING MEANS FOR A FUEL VALVE      ABSTRACT OF THE DISCLOSURE       The invention comprises a control valve which is interposed between a hydraulically-operated fuel valve (for an engine) and a hydraulic fluid supply for regulating the operation (i.e, the opening and closing) of the fuel valve.  The control valve has a housing-enclosed, sliding plunger which is spring-loaded to urge the plunger in a first direction in the housing, and which is translated in a second, opposite direction against the spring bias, by a contacting, rotating cam.   Hydraulic fluid inlet and outlet ports are formed in the housing and are cyclically communi-cating and closed off from each other, for given periods of time, due to the translations of the plunger.  The housing has an adjusting element operative for altering the translation of the plunger relative to the housing, to alter the given time periods and, as a consequence, the fuel valve is selectively and adjustably regulated thereby.
