摘要： Disclosed is a system and method for a non-invasive method for determining the presence or absence of cancerous cells in the skin and deeper tissue levels. The system includes a portable handheld laser coupled with a spectroscopy system to produce real-time material analysis of the presence of cancerous cells without sample preparation. The system focuses a high peak power laser pulse onto a targeted material to produce a laser spark or micro-plasma. Elemental line spectra emission is created, collected and analyzed by a spectrophotometer. The line spectra emission data is quickly displayed on a laptop computer. “Eye-safe” Class I lasers provide for practical in-situ laser plasma spectroscopy applications such as detection of cancerous skin tissues. The emission data can be used to detect changes in the levels of a series of elements that are associated with cancerous cells versus normal skin cells. The system also finds use during excisional biopsy procedures to ensure that all cancerous cells have been removed.

摘要： A no solid bed extruder screw for processing a material to a molten state has a body with a helical thread having pushing and trailing surfaces, he body extending longitudinally between feed and discharge ends. A channel for receiving the material to be processed is formed between the body outer surface and an outer diameter of the thread bounded by the pushing surface and the trailing surface. A volume of the channel decreases in a plurality of revolutions of the thread in a direction from the feed end to the discharge end. A channel depth between the pushing surface and the trailing surface decreases for a first portion of the channel toward the feed end and increases for a second portion of the channel toward the discharge end. At least one of the channel portions has a constant width and includes varying width sub-channels.

摘要： An extruder-mixer has a plurality of rotor rings provided on the downstream end of a motor driven extruder shaft mounted for rotation in a conventional heated barrel or stator. The rings comprise a plurality of spaced driven rotor rings spaced apart from each other and a plurality of non-driven but rotatable floating rings interleaved between each pair of driven rotor rings. Both rings have parallel upstream and downstream faces between which polymer flow passageways extend so that the polymer melt moves downstream first through one type of ring followed by movement through the other type of ring and the viscosity of the melt causes the rotatable floating rings to be rotated by the driven rings at a slower speed than the driven rings so that shearing force on the melt effects mixing of the melt.

摘要： A feedscrew for an extruder or molding apparatus has an elongated body with a helical thread formed thereon defining a first channel "A ". At the start of a mixing section, a channel "B " is cut in the center of the channel "A " and both channels are of the same pitch. The channels start at the same depth, but the channel A decreases in depth to a minimum and the channel B increases in depth to a maximum. The channel B then decreases in depth to a minimum and the channel A increases in depth to a maximum where the channels are again at the same depth. This channel within a channel configuration is repeated along the mixing section. The purpose of the arrangement is to compress and decompress the material being fed through the assembly to obtain the desired mixing action for low shear homogenization of the viscous plastic polymer.

摘要： A check valve for use in controlling the flow of thermoplastic material in an injection molding apparatus includes a valve body having an axially extending chamber formed therein with an inlet opening and an outlet opening through which the material can flow. An poppet is slidably movable in the chamber between a valve closed position and a selected valve open position. The poppet has an inlet end with a conical shape and the chamber has a complementary taper portion adjacent the inlet opening, the inlet end and the taper portion sealingly cooperating for preventing flow of material through said chamber when said poppet is in the valve closed position. An adjusting ring is positioned in the chamber for selective movement between a minimum open position and a maximum open position, the adjusting ring being externally threaded for threadably engaging an internal thread formed in the chamber. The poppet has a plurality of radially extending tabs formed thereon for abutting the adjusting ring when the poppet is in the selected valve open position whereby the volume of flow of material through the chamber is porportional to the position of the adjusting ring in the chamber. The poppet also has a plurality of axially extending grooves formed therein for permitting the flow of material from the inlet end of the poppet to an opposite end of the poppet and out the outlet end of the chamber.

摘要： A plastic melt machine includes a feed screw rotatably mounted in a barrel and driven in rotation about a longitudinal screw axis of the feed screw by a screw drive to plasticize material, and an apparatus for driving a device independently of the feed screw. The device can be any rotatable device associated with the feed screw wherein the device is rotatable about a drive axis and is in fluid communication with the barrel to receive the plasticized material. The drive axis is coaxial with the screw axis. A drive shaft couples the device to the device drive, or to the screw drive through a speed changer, for rotating the device independently of the rotation of the feed screw by the screw drive.
