Abstract: APPLICATION FOR LETTERS PATENT FOR       THERMOELECTRIC DEVICE AND PROCESS FOR MAKING THE SAME          ABSTRACT OF THE DISCLOSURE      There is disclosed a portable refrigerator which is formed by casting an insulating wall of foamed-in-place insulating foam in a manner which provides inner and outer shell portions on the insulating wall and a depression therein which exposes a surface of the internal thermal sink and, except for a pigtail and posi-tive and negative contact points which points project through the outer shell portion in position to be connected with the positive and negative poles, respectively, of the thermoelectric element, completely imbeds the electrical connections.  A thermo-electric element is disposed in the depression in heat-exchange with the surface of the internal thermal sink exposed by the depression and the positive and negative poles of the thermo-electric element are connected with the respective positive and negative contact points.  An annular gasket of resilient and compressible sealing material is disposed on the outer shell in position such that it completely surrounds the depression and the thermoelectric element therein and covers the contact points.          An external thermal sink is disposed in sealing contact with the sealing gasket and the two thermal sinks are drawn toward each other until the gasket is compressed and the thermal sinks are in heat-exchange with the thermoelectric element.  The thermoelectric cooling device has a rim extending around but spaced from the external thermal sink of such height that the edge of the rim and the outermost surfaces of the external thermal sink are substantially in a common plane.

Abstract: ABSTRACT OF THE DISCLOSURE           Used oils, especially used lubricating oils which are normally considered waste and are discarded or burned, are reclaimed for reuse by a re-refining procedure involving the steps of:         (a)  heat soaking the used oil;           (b) optionally  stripping the heat soaked oil under conditions sufficient to remove the low boiling conversion products from the heat soaker, (c) distilling the heat soaked oil;      (d)  passing the distillate through a guard bed of activated materials;       (e)  hydrotreating the guard bed treated dis-tillate under standard hydrotreating conditions.            If the used oil to be rerefined contains a quantity of water and/or fuel fraction which the prac-titioner considers sufficiently large to be detrimen-tal,   the   used   oil   may  be   subjected   to   a dewatering/defueling step prior to being heat soaked.

Abstract: ABSTRACT OF THE DISCLOSURE    Method and apparatus are disclosed for determining one or more physical characteristics of individual bubbles in a gas-liquid system and a gas-liquid-solid system at high temperatures and pressures.  An in situ probe device is inserted into the system over which individual bubbles flow.  The probe device has a plurality of independent probes.  Each has a rounded fibre optic end portion projecting into the system.  A source of incident light is directed onto each of the probes.  The rounded end portion of each probe is formed with a radius of curvature sufficiently large whereby the angle of incidence of the source light at the rounded portion is greater than the angle of total reflection for the fibre optic when in contact with the gas.  The angle of incidence is less than the angle of total reflection for the fibre optic when in contact with the liquid.  The plurality of probes are spatially arranged to detect one or more of the bubble physical characteristics as a bubble flows over the probe device. The change in light intensity of reflected light emerging from the probe is measured.  The change in light intensities of each of the probes over time is evaluated to determine the one or more bubble characteristics. Each probe is formed of sufficiently thin fibre optic and spaced from the other probes of the device to enable detection of the bubble characteristics for individual bubbles flowing over the probe device. This probe system enables the monitoring of physical characteristics of bubbles in two and three phase systems in an efficient, reliable, economical manner. The system also provides for a measure of solid, gas and liquid hold-ups in a three-phase system.

Abstract: ABSTRACT OF THE DISCLOSURE         Mounting means for plate cylinders of a printing machine having replaceable sleevelike plate cylinder shells.          Apparatus for rotatably mounting plate cylinders on a printing machine, such as a flexographic printing machine, that includes removable sleevelike plate cylinder shells, and for facilltating installation and removal of the cylinder shells.  During replace-ment of each plate cylinder shell, one journal of the plate cylinder core is supported by the frame of the printing machine.          The other bearing support is withdrawable from the other journal and includes a beaning support bracket that is axially displace-able relative to the axis of the plate cylinder by a carriage carried on tracks that have ends secured to a pivotable yoke to permit the other beaning support to be axially withdrawn from the plate cylinder journal and to pivot outwardly.  The tracks are adapted to be locked at their inner ends to the machine frame or to the plate cylinder carriage.  The pivotable yoke and the tracks for the bearing bracket constitute the end structure of the plate cylinder carriage on one side thereof and permit quick removal of the plate cylinder shell.  Hydraulic piston-cylinder units are provided on both sides of the bearing support which is not withdrawn for supporting the plate cylinder core, and are mounted on the machine frame or on the plate cylinder carriage.          The respective piston-cylinder units counterbalance the pivot movement of the plate cylinder to support it when the opposite bearing is removed to permit removal or installation of a plate cylinder.

Abstract: ABSTRACT OF DISCLOSURE     A twin bobbin double twist buncher in accordance with the present invention includes inlet guide means at each axial end of a bow strander or twister which accepts another group of wires or strands.  Each group of wires or strands are twisted by another one of two wire carriers in the nature of bows and subsequently wound onto one of two reels disposed or supported within the mchine.          This is not to say that both sets of wires cannot be run on the same bow.  It is simply convenient to use the idle bow provided on many conventional bow-type machines for this purpose.  The axes of the two bobbins or reels may be oriented in any position relative to the axis of the twister.  The most common configurations include the orientation where the axis of both bobbins or reels are coaxial with the axis of the machine or alternatively, perpendicular to the axis of the machine.  In either case, an individual traverse or a common traverse may be used to distribute the bunched wires or strands across the surface of the reel or bobbin.  This buncher has increased capabilities and advantageously can share common drives thus reducing capital costs.
