Title: Controlling the porosity and permeation of a web
Inventor: CALDWELL JAMES MICHAEL
IPC: D21H17/59
Filed: 1996-05-16
Abstract: Products and methods for controlling the porosity and permeation of a web are provided using a curable thixotropic shear thinnable polymer composition that preferably encapsulates a plurality of fibers of the web and/or forms an internal layer within the web. Webs suitable for several different uses are featured, for example medical garments resistant to permeation by a virus or bacteria. The effective pore size of the web is controlled by regulating various factors such as the thickness of the polymer composition encapsulating the fibers and the thickness and placement of the internal polymer layer. Other factors include the polymer density, structure, and crosslinking orientation, as well as the diffusion, permeation and sorption of the polymer.

Title: Hanger sheet and tape dispenser combination
Inventor: SAMUELSON BRUCE E
IPC: B65H35/00
Filed: 1996-06-05
Abstract: A combination (9) of a tape dispenser (10) including a molded polymeric frame (14) and cutting blade (18) on a blade support portion (20) of the frame, and a hanger sheet (8) (e.g., of card stock and printed trademark and use information) having a first end portion (50) engaged with the frame of the dispenser and a second (52) portion projecting from the dispenser and having an opening (54) adapted to receive a peg in a sales display area so that the tape dispenser can be hung from the peg by the hanger sheet. The blade support portion of the dispenser comprises a plurality of spaced projections (22) from an inner surface (17) of a dispenser wall that have generally coplanar distal end surfaces (21) on which the blade is mounted. The first end portion of the hanger sheet has openings receiving the projections with the first end portion of the sheet around the projections, between the cutting blade and the inner surface of the wall supporting the projections. The hanger sheet can be separated from the dispenser by tearing it along the lines of weakness intersecting those openings.
Patent CA-2227157-A1 (CA)
Inventor: VARTY GUY THOMAS
IPC: G01C19/5691
Filed: 1998-01-15
Abstract: The invention is a vibratory rotation sensor comprising a resonator and a resona tor housing and a method for controlling and reading out the sensor utilizing multiplex elec tronics. The resonator is a rotationally-symmetric thin-walled object that can be made to vib rate in a plurality of standing-wave modes. One or more electrodes are attached to a surface of the res onator and connect to a single output port The housing has a plurality of attached electrodes in cl ose proximity to the resonator electrodes. The method for controlling and reading out the vibratory r otation sensor includes applying driving voltages to the housing electrodes and determining the parameters of the standing waves by performing operations on the resonator signal that emerges fro m the resonator output port. A driving voltage may include either an excitation voltage or a for cing voltage or both. An excitation voltage has essentially no effect on the resonator dynamics but ca rries information pertaining to the standing-wave parameters when it arrives at the resonator outp ut port. A forcing voltage causes forces to be applied to the resonator and thereby affects the dyn amics of the resonator and the standing-wave parameters. The driving voltages applied to the housing el ectrodes are brought together into a single resonator signal as a result of being transmitted through the housing-electrode-resonator-electrode capacitances to the resonator output port. In order to extract the standing-wave parameters the excitation and forcing voltages are designed to be separable by appropriate operations performed on the resonator signal.

Patent CA-2239998-A1 (CA)
Title: Electronic emergency brake load weigh device
Inventor: MAZUR RICHARD J
IPC: B61H13/30
Filed: 1998-06-08
Abstract: An electronic load weigh device is used with a railcar truck control unit. A relay valve provides to a brake cylinder a pressure proportional to the pressure impinging upon its control port. A first feedback signal is indicative of the pressure at the control port. A second feedback signal is indicative of the load borne by the truck. A pressure switch opens when pressure within a trainline changes to a level indicative of an emergency. By controlling the opening and closing of application and release magnet valves, a controller controls the pressure impinging on the control port and thereby service braking of the wheels of the truck. The load weigh device includes (i) circuitry for electronically compensating for the load during braking and (ii) a mechanism for granting the circuitry exclusive control over the magnet valves. Should such emergency occur, the mechanism responds to such emergency by disconnecting the controller from the magnet valves. This gives the circuitry exclusive control over the magnet valves.      The circuitry compensates for the load borne by the truck during emergency braking by selectively opening and closing the magnet valves, according to predetermined criteria using the feedback signals, thereby controlling the magnitude of the pressure impinging upon the control port. Absent such emergency, the mechanism responds to such absence by connecting the controller to the magnet valves whereby such service braking on the truck is normally controlled, yet the circuitry is still enabled to compensate for the load during such service braking.
