Patent CA-2100320-C (CA)
Inventor: DEANER MICHAEL J
IPC: C08L97/02
Filed: 1993-07-12
Granted: 2011-02-08
Abstract: The invention relates to a composition comprising a polymer and wood fiber composite that can be used in the form of a linear extrudate or thermoplastic pellet to manufacture structural members. The polymer and wood fiber composite structural members can be manufactured in an extrusion process or an injection molding process. The linear extrudate or pellet can have a cross-section of any arbitrary shape, or can be a regular geometric. The pellet can have a cross-section shape having a volume of at least about 12 mm3. Preferably the pellet is a right cylindrical pellet having a minimum radius of about 1.5 mm and a minimum length of 1 mm weighing at least 14 mg. The invention also relates to an environmentally sensitive recycle of waste streams. The polymer and wood fiber composite contains an intentional recycle of a waste stream comprising polymer flakes or particles or wood fiber. The waste stream can comprises, in addition to polymer such as polyvinyl chloride or wood fiber, adhesive, paint, preservative, or other chemical stream common in the wood-window or door manufacturing process, or mixtures thereof. The initial mixing step before extrusion of the composite material insures substantial mixing and melt contact between molten polymer and wood fiber. The extruded pellet comprises a consistent proportion of polymer, wood fiber and water. During the extrusion, water is removed intentionally to dry the material to a maximum water content of less than about 10 wt-% based on the pellet weight. To make a structural unit, the pellet is introduced into an extruder or injection molding apparatus wherein, under conditions of temperature and pressure, the composite pellet material is shaped into a useful cross-section. Alternatively, the extruded thermoplastic mass, in the form of a elongated linear extrudate without a pelletizing step, can be immediately directed after formation into an extruder or injection molding apparatus.

Title: Method and structure for electronically measuring beam parameters
Inventor: PRIOR RICHARD W
IPC: G01T1/29
Filed: 1994-03-07
Granted: 2000-02-29
Abstract: A method of electronically measuring parameters of an beam in a raster scan system includes the steps of, choosing a predetermined pixel to be calibrated, moving a grid adjacent this pixel, strobing the beam, incrementally moving the beam toward an axis of the grid, and integrating the signal resulting from the beam as the beam moves toward the axis. The steps of strobing the beam, incrementally moving the beam, and integrating the signal are repeated until the beam crosses the axis. The value of the accumulated signals, provided for example by a charge amplifier, is used to determine the relative position of the axis of the grid. The value of the accumulated signals associated with another axis is also determined. The relative positions of the two axes determine the relative location of the grid. If the grid location is known, the location of an associated substrate which is typically adjacent the grid is also known.

Filed: 1995-03-27
Granted: 1999-12-28
Abstract: The present invention provides a method and an apparatus for enhancing communication that use spread spectrum technology. The method of processing a signal includes applying a spread spectrum encoding process to the signal where the improvement includes applying a first error protection process to a significant portion of the signal and a second error protection process to a less significant portion of the signal. The first error protection process provides a greater amount of error protection than the second error protection process. The actual step of applying the error protection processes can include, for example, applying a variable rate coder to the signal to generate an intermediate modulated signal and applying a variable time modulator to the intermediate modulated signal.

In another embodiment at least two waveguide applicators are positioned on opposite sides of the compression means so that the compressed breast is positioned between the opposed apertures of the waveguides. An electric field probe is placed into a target within the breast to assist in focusing the electric field energy into the target.
