Abstract: A process for producing a high VI/low volatility lubricating oil basestock. The process comprises subjecting the raffinate from a solvent extraction step to a two-step, single-stage hydroconversion process wherein the first step involves severe hydroconversion of the raffinate followed by a cold hydrofinishing step. The effluent from the cold hydrofinishing step is then catalytically dewaxed or in the alternative, solvent dewaxed followed by catalytic dewaxing.

Abstract: A label printer and applicator system which determines the height and position of moving objects on a conveyor while printing labels and positioning the labels for application on the moving objects. The printer/applicator includes a controllable label buffer, applicator actuator and label ejector to receive and apply the printed label, or eject the label when it has been determined that the application to the object cannot be made. Further embodiments include multiple applicators deployed along the conveyor to permit higher conveyor velocities and avoidance of unlabeled objects due to height/proximity relationships with adjacent packages.

Abstract: An instrument monitors the coangulation of coagulable fluid blood, blood fraction or a control by combining the coagulable fluid with particles which are affected by a magnetic field so that the particles become suspended relatively freely in the fluid. A time-varying magnetic field causes the particles to be reoriented as the magnetic field varies. The reorientation changes as the fluid coagulates owing to the fluid's changing viscosity. An electromagnet creates the time-varying magnetic field. The electromagnet includes a core comprising a first leg an electrically conductive coil for creating a time-varying magnetic flux in the core, and a return for the time-varying magnetic flux. The first leg and the flux return together comprise a generally H-shaped core of ferromagnetic material. A bobbin is provided on the first leg and the electrically conductive coil is wound on the bobbin.
