  • Patent number: 9039898
    Abstract: Different components of natural oils are separated by forming solid complexes of components of the natural oil with a solvent, and then separating the solid complexes from the remaining liquids. The natural oil is cooled in the presence of a solvent, and at least one component of the oil forms the solid complex with the solvent. This solid complex is separated from the remaining liquid portion of the oil solution, which also contains the solvent. Additional options concentration steps can further concentrate the components left in the liquid phase.

  • Publication number: 20130206317
    Abstract: Each platform mounted mold assembly for plastic tubing includes a circuit board containing parameters defining elements of the forming, molding, tipping or welding operation to be undertaken on the tubing. A control unit includes an RF generator for providing the RF energy to effect the forming, molding, tipping or welding process, a source of air under pressure to operate the mechanical elements attendant each mold assembly, various sensors and a multiplex unit. In operation, the control unit serially addresses each of the mold assemblies, senses the parameters attendant the mold and applies the appropriate power level of RF energy for a specific duration and temperature while activating the mechanical aspects of the mold assembly. The mold assemblies may be serially activated through a multiplex unit or in a particular sequence that may be operator controlled.

  • Patent number: 8469690
    Abstract: Mandrel supported IV tubing is inserted within a mold of a mold assembly to heat the IV tubing and form a tapered end of the tubing. The tip of the tubing extending beyond the tapered end of the tubing is severed by the mandrel bearing against the mold to lodge the tip in an outlet of the mold. Cooling air is introduced to the mold assembly to cool the mold and to create a flow of turbulent air about the outlet of the mold to extract the severed tips. The turbulent air is exhausted through a channel, pipe and fitting into a collection chamber and causes translation of the severed tip to and into the collection chamber. Sensors may be incorporated to sense the translation of the severed tips.

  • Publication number: 20120038315
    Abstract: A plurality of serially connectable lithium based batteries provide power to a load upon actuation of a user operated switch. Upon actuation of the user operated switch, additional switches intermediate adjacent batteries close to serially connect the batteries to one another and a load. A signal from the load maintains these additional switches closed. A charging circuit is associated with each battery to charge the batteries in parallel upon opening the additional switches. Sensors for temperature, current and various other parameters provide signals to one or more controllers to prevent damage upon the presence of a fault indication signal.

  • Patent number: 7871701
    Abstract: An oriented strand board for structural applications and a method of its production comprising elongated strands having aspect ratios greater than 2, the strands being derived from the outer shells of oil palm tree fronds formed as a bi-product of the harvest of oil palm fruit, such that the strand length is limited to about a meter, the strands being cut from the outer shell area of the fronds and at least the outer regions of the major faces of the board being substantially free of core material, the shell strands being combined with a heat settable binder material, the strands being formed by elongated blades moving relative to a frond length in planes generally aligned with a longitudinal direction of the frond length, the strands of the frond shells being arranged and being permanently bonded together such that they are predominately generally aligned with the structural direction of the board at least at the outer regions of the major faces of the board.

  • Patent number: 7744805
    Abstract: A mold for forming, molding or welding thermoplastic tubing extends through the aperture of an apertured spool supporting an RF energized coil to inductively heat a center section of the mold. A source of air is channeled through a manifold to flow about the center section of the mold and through the space between the mold and the aperture in the spool to rapidly cool the mold. Thermal chokes on each side of the center section of the mold impede heat transfer and a heat sink connected to each thermal choke serves to dissipate any heat build up. The spool may be translated along the center section of the mold to a predetermined location commensurate with a predetermined heat profile. The mold includes a passageway extending therethrough for receiving the tubing; by appropriate dimensioning, the passageway will accommodate the use of a mandrel to support the tubing to be formed, molded or welded.

  • Publication number: 20090302033
    Abstract: A body of an automated hand held tubing sealer encloses an electric motor, a drive train responsive to the electric motor, a source of RF energy, a switch for initiating operation of the electric motor and limit switches for controlling operation of the source of RF energy as a function of the drive train and a programmable microprocessor for controlling and varying any of numerous parameters. A sealing head assembly is formed by a fixed jaw and a movable jaw to compress tubing placed therebetween in response to operation of the drive train and to melt the compressed tubing as a function of operation of the source of RF energy. A fitting permits selectively detachably attaching the sealing head assembly with the body at any of more than one angularly displaced positions.

  • Patent number: 7326897
    Abstract: A clip on welder includes two pairs of opposed grippers defined by pivotally attached upper and lower frames for latching the welder to heat weldable material, such as a length of tubing, upon actuation of a start button by an operator; thereafter, the welder operates unattended. At least a jaw of a pair of jaws disposed intermediate the two pairs of grippers heats the material compressed and lodged therebetween to form a weld in or across the material. A source of gas, such as air, under pressure selectively connected to a bellows provides the power to pivot the upper and lower frames into gripping engagement with the material. A source of electrical signals provides the power to heat the material intermediate the pair of jaws. One or more thermocouples senses the heat of the jaws and generates signals used to control the application of power and to control cooling. After completion of the weld, cooling air is directed to the jaws until the thermocouple(s) signal(s) indicates a sufficiently low temperature.
