Patent CA-2291089-A1 (CA)
Title: Method of producing wood strips for conversion into composite lumber products
Inventor: SELBY JOHN S
IPC: B27L5/06
Filed: 1998-06-04
Abstract: The invention is a method for producing flitches (12) prepared from roundwood logs (2), to the manufacture of wood slices or slats (20) from the flitches (12), and to the methods of combining the strips into composite lumber products. The method is based in part on the concept of preparing flitches (12) that retain the sweep or natural longitudinal curvature of the log and slicing around the sweep to prepare the slats (20) for further conversion into composite lumber products.      An opening cut (4) is made in the log (2) essentially following or parallel to the curve of any sweep to divide it into two approximately equal volume pieces. An opposing surface (14) is machined parallel to the surface generated by the opening cut to produce a flitch. The flitches (12) are then sliced around the sweep curvature to produce slats (20). The natural surface of the log is preferably retained on the sides of the flitches. Slats may then be edged and adhesively combined in various ways to produce composite lumber products. The method achieves an especially high yield from raw logs of products that simulate solid sawn lumber in appearance, properties, and ease of use.

Title: Force feedback control wheels and knobs
Inventor: SCHENA BRUCE M
IPC: G05G9/047
Filed: 1999-03-24
Abstract: A force feedback wheel or knob is provided on a mouse or other device to be manipulated by a user. In one embodiment, a rotatable wheel is mounted upon a manipulandum, such as a mouse, and rotates about a wheel axis, where a wheel sensor provides a wheel signal to a host computer indicating a rotary position of the wheel, and a wheel actuator coupled to the rotatable wheel applies a computer-modulated force to the wheel about the wheel axis. The force applied to the wheel can correspond with an event or interaction displayed in a host graphical environment. In other embodiments, a knob on a device allows a user to control functions of the device. The knob is rotatable in a rotary degree of freedom and can be moved in a transverse direction perpendicular to the axis of rotation and/or moved in a linear degree of freedom, allowing the knob to be pushed or pulled by the user. Force feedback is preferably provided using an actuator coupled to the knob. The device controlled by the knob can be, for example, an audio device, a video device, etc. Detent forces can be provided for the knob by overlapping and adjusting ranges of closely-spaced detents in the rotary degree of freedom of the knob.

IPC: A61B18/14
Filed: 2000-02-28
Abstract: According to the invention there is provided an electro-surgical pencil of a type having an electrode projecting out one end of said pencil, an electrical coupling operative to couple the electrode to an external electrical source. The pencil has an elongated housing having a hollow interior passageway, an open electrode end through which the electrode projects and an open end opposite to the electrode end couplable to a vacuum source. The hollow interior passageway is of a diameter sufficiently large to permit a flow and velocity of air sufficient to aspirate and evacuate smoke produced by the pencil.      An electrode support in the hollow interior passageway holds the electrode. The electrode support and the electrode present a cross-sectional area which is substantially less than that of the hollow interior passageway. An optical switch is coupled to the elongated housing. An optical reflector having at least two different types of reflective surfaces is also coupled to the elongated housing proximate the optical switch, and a light fibre is coupled to the switch. An end of the light fibre is proximate the reflector, and is positionable to reflect light selectably from one of the two different types of reflective surfaces back up the light fibre.

Title: Showerhead engine assembly
Inventor: PETROVIC JOHN E
IPC: B05B15/522
Filed: 2000-04-07
Abstract: The showerhead engine assemblies provide different combinations and variations of continuous, deflected, pulsating sprays, and aeration spray patterns including those that are adjustable enabling wide variations in the degree of aeration of the water passing through the showerhead, enabling wide variation of the characteristics of the water spray patterns.  The spray patterns include a nondeflected, nonpulsating spray pattern; a deflected nonpulsating spray pattern; a nondeflected, pulsating spray pattern; and a deflected, pulsating spray pattern, while enabling the engine assembly to be self-cleaning. For pulsating spray modes, the showerhead engine assembly includes but five plastic parts and an O-ring seal; the parts being a stator, a spinner, an engager, a pressure plate, and a faceplate, openings beings disposed in the pressure plate and faceplate to enable fluid flow therefrom. Deflecting surfaces on the faceplate enable a variety of different flow patterns. Spinner rotation starts or stops depending upon the position of the spinner relative to the stator, since the stator includes a pair of stop flanges that engage and disengage with the spinner. When the spinner is disengaged and free to rotate, water flow through passages in the spinner cause spinner rotation, creating a vortex and pulsating spray patterns. The series of showerhead engine assemblies include component parts that are interchangeable, the number of component parts being minimal, the interchangeability reducing the number of spare parts necessary to repair the series of showerhead engine assemblies.
