Abstract: MOLD CLAMPING FOR INJECTION BLOW         MOLDING     ABSTRACT OF THE DISCLOSURE     This invention is an improved injection molding ap-paratus, and more specifically an injection blow molding machine.  An injection mold and/or other molds have a movable part that is moved toward and from a fixed part to open and close the mold.  Hydraulic motors supplied with high pressure liquid holds the molds closed.  In order to conserve high pressure liquid, a small motor is used to open and close the molds and to move a piston of the high pressure hydraulic motor. Liquid under little or no pres-sure is drawn into the hydraulic motors as they are moved by the small motor.  When the molds reach closed position, communication of the hydraulic motors with the low pressure liquid supply is cut off, and high pressure liquid is supplied to the hydraulic motors.  The preferred construction has all of the movable parts of the molds connected with a frame.  Special motion-transmitting means maintain the frame against tilting.

Abstract: LIQUID TIGHT CONNECTOR WITH IMPROVED GROUND CONDUCTIVITY           Abstract of the Disclosure A liquid tight connector for joining a liquid tight flexible conduit to a junction box or panel and having improved ground continuity is provided.  The connector includes a body member having a cast-on lug to which an external ground may be secured.  To provide a liquid tight seal between the fitting and the junction box, channel or raceway, an O-ring or similar seal is provided.  The O-ring is placed in a recess whose depth and cross section are so related to the size and characteristics of the O-ring, that when the O-ring provides a liquid tight seal, a metallic surface of the body is in contact with the joined metallic member.  With this increased metallic contact, there is an improved capacity to conduct fault current.  The recess may be positioned to provide substantial contact area on an appropriate side of the perimeter of the O-ring.  This pro-tects the contact area from rust and/or corrosion which would reduce the fault current  carrying capacity.  Serrations, or other means, may be provided to improve the contact between the connector and the joined member and to minimize any tend-ency to loosen due to vibration.  The principles may be adapted to a wide variety of fittings.

Abstract: ABSTRACT OF THE DISCLOSURE       A process and apparatus for separating isotopes by selective excitation of isotopic species of a volatile compound by tuned laser light.  A highly cooled gas of the volatile compound is produced in which the isotopic shift is sharpened and defined.  Before substantial condensation occurs, the cooled gas is irradiated with laser light precisely tuned to a desired wavelength to selectively excite a particular isotopic species in the cooled gas.         The laser light may impart sufficient energy to the excited species to cause it to undergo photolysis, photochemical reaction or even to photoionize.  Alternatively, a two-photon irradiation may be applied to the cooled gas to induce photolysis, photochemical reaction or photoionization.         The process is particularly applicable to the separation of isotopes of uranium.

Abstract: TITLE          PIPE DELIVERY SYSTEM AND METHOD FOR DELIVERING PIPE            ABSTRACT OF THE DISCLOSURE          A pipe delivery system and method in which pipe is fed to the drilling rig floor by carrying the pipe in a single elongated skate along a horizontal and then upwardly inclined ramp so that the end of the pipe can be hoisted upwardly off the skate.  Pipe is kicked off the skate laterally onto pipe delivery ramp plates by pushing ejector plates carried by the skate upwardly into an angle to cause the pipe to roll off the skate and down the delivery ramp plates.  The ejector plates are actuated by pistons and cylinders housed in a re-tracted position below the path of the skate and which are extended upwardly against the ejector plates.  The pipe is delivered by gravity rolling the pipe either from or to the skate by selectively positioning ramp plates with the de-sired lateral inclination at each side of the skate and providing indexing fingers which are movable into the path of the pipe on the ramp for separating an endmost pipe for removal.  Pipe is transferred between vertically spaced layers of pipe racks and the skate location by rollers which are powered to move the pipe along the pipe axis and which are also vertically positionable for carrying the pipe between the delivery ramp plates and the various layers of the pipe racks.

Abstract: Abstract of the Disclosure The invention relates to hard magnetic materials, a process for shaping such materials and devices utilizing materials so shaped.  Shaping is accomplished by steps including working, with at least some critical part of the working being conducted at low temperature, sometimes at room temperature.  Magnetic properties are sufficient to permit use in many magnetically biased devices, such as electroacoustic transducers, including receivers, loud-speakers, and the like.  Alloy compositions based on ternary alloys of the chromium-cobalt-iron system modified by addition of zirconium, molybdenum, niobium, vanadium, titanium, and/or aluminum, are found to manifest improved formability.  Examplary compositions are magnetic and evidence coercivities of 350-550 Oe., remanent magnetiza-tions of from 10,000 - 7,500 gauss, and maximum energy products in excess of one million.  Improvement in formabilty may take the form of room temperature stamping, sometimes in air, to final configurations including curvatures of radius equal to thickness.  Novel compositions particularly desirable from such standpoint necessarily contain zirconium together with aluminum, niobium, and/or titanium.
