Patent CA-2287199-A1 (CA)
Title: Patterned abrasive tools
Inventor: MABON ROLAND
IPC: B24D3/00
Filed: 1998-03-19
Abstract: A method of making a metal bonded, abrasive tool uses a perforated stencil to place abrasive parcels in a pattern on the cutting surface of the tool.      The stencil is placed against the tool preform so that the perforations define cavities.      Metal brazing composition in the form of a paste is packed into the cavities and the stencil is removed to leave discrete parcels of brazing paste tacked to the cutting surface.      Abrasive grains are deposited onto the paste particles and fixed in place by firing the preform at brazing conditions.      The abrasive grains thus are precisely positioned and spaced apart on the cutting surface by abrasive free channels which are defined by the web of the stencil. The abrasive free channels provide paths to facilitate flow of coolant material and swarf particles at the cutting zone. The method can include initially placing the brazing paste parcels onto a resilient, transfer medium and subsequently transferring the parcels onto the preform cutting surface. This method is particularly useful for depositing an abrasive pattern on a non-planar or highly curved tool surface. In another contemplated variation of the invention, the abrasive grains are premixed with the brazing paste prior to filling the cavities.

Title: Multilayer porous fabric
Inventor: WIEBE KURT
IPC: D21F7/08
Filed: 1999-03-16
Abstract: A multilayer porous fabric comprises a porous core fabric provided with a plurality of suitably located hook means structures on at least one of its surfaces. At least one layer of nonwoven fibrous batt, pre-needled to a desired density, is attached by entanglement onto the hook means by pressing the core fabric and batt together, so that the hook structures engage with and entangle sufficient fibers from the batt to anchor the batt reliably to the core fabric without further needling. The multilayer fabric is then ready for use without further processing and can be handled before use, for example in preparation for installation in a papermaking machine press section. The porous core fabric may be formed by weaving or as an extruded sheet. Compressive loads applied to the porous fabric may enhance the level of entanglement of the batt onto the hook means.

Title: Synchronizing multiple steering inputs to marine rudder/steering actuators
Inventor: PATERSON DOUGLAS F
IPC: B63H25/04
Filed: 1999-12-29
Abstract: A steering system (100) includes an incremental helm (102), a control panel (104), and an autopilot (106) that are electrically connected to a command processor (108). The steering system further includes an autopilot attitude controller (110) and an incremental servo (112) for actuating the rudder. The incremental helm acts as a course selector for the autopilot. Upon autopilot engagement, the set heading is the current heading plus any heading change received from the helm after engagement. A course selection controller (120) employs a helm increment summer (122) and a washout filter (124) that are initialized to zero upon engagement. The washout filter follows short-term course changes but forgets them over a longer time. A disengage threshold block (126) receives the washout filter output and disengages the autopilot if the threshold is exceeded. The course selection controller allows a helmsman to make occasional course changes without automatically disengaging the autopilot unless the helmsman rotates the helm at a rate that exceeds the threshold. Upon disengagement, the autopilot is inhibited from re-engaging for a short time, after which the autopilot can re-engage when the turning rate approaches zero. The steering system further includes a helm rotation stop that provides the helmsman with rudder stop position feedback, responds to the rudder stops regardless of the current steering ratio, incorporates a powerful braking action with a low-power mechanism, and provides unidirectional braking at either rudder stop in response to a single steering limit signal.

Patent CA-2303257-A1 (CA)
Inventor: MARON ROBERT J
IPC: G01L11/02
Filed: 1998-09-01
Abstract: A pressure sensor capable of measuring pressure in a harsh environment includes at least one intrinsic fiber optic sensor element formed within a core of an optical fiber. A length of the optical fiber containing the sensor element is attached to a pressure sensitive structure. A dimension of the pressure sensitive structure changes in response to changes in the pressure of a pressure field of the environment. The sensor element is responsive to an input signal and to a strain caused by changes in the dimension of the pressure sensitive structure for providing a pressure signal indicative of the pressure. A temperature compensation sensor is also formed in the fiber near the location of the pressure sensor. The temperature sensor is isolated from strain associated with the pressure for providing temperature compensation of the pressure sensor. Alternatively, temperature compensation is provided by an intrinsic fiber optic sensor element mounted to experience an equal but opposite strain associated with changes in the dimension of the pressure sensitive structure.

Abstract: A method for preparing frozen par-fried potato strips comprising about 32% to about 52% moisture which remain fresh tasting after storage at about 0 ~F (17.8 ~C). The method comprises peeling, trimming and cutting raw potatoes into strips, blanching, and reducing the moisture content of the potato strips to not less than about 54%, followed by par-frying the potato strips in oil for a time sufficient to reduce the moisture of the potato strips to a final moisture content of from about 32% to about 52%. Thereafter, the par-fried potato strips are frozen. The frozen par-fried potato strips have reduced levels of 2,5-dimethyl pyrazine and relatively high levels of 2,4-decandienal. When cooked, the finished French fries have improved flavor over conventional oven baked fries.

IPC: B60T17/22
Filed: 2000-07-13
Abstract: A portable device permits testing of an EOT unit of a two-way end-of-train (EOT) radio telemetry system. During the test, the EOT unit may be mounted to and fully installed on the railcar on which it is to be used. The portable device includes a microprocessor unit, a display, and a transceiver that enables the invention to communicate with the EOT unit. The portable device also includes a mechanism for authorizing the portable device to communicate with the EOT unit. Used to control the overall operation of the portable device, the microprocessor unit operates the transceiver in cooperation with the aforementioned mechanism so as to authorize the portable device to communicate with the EOT unit according to an arming procedure. The microprocessor unit also operates the display on which the progress and completion of the arming procedure is indicated. When the portable device is authorized to operate with the EOT unit, the display is directed to indicate operational data that it receives from the EOT unit pertaining to the railcar to which the EOT unit is connected. The portable device further includes a mechanism for initiating an emergency reduction in pressure within the brake pipe of the railcar.      When the emergency initiating mechanism is activated, the microprocessor unit commands the transceiver to transmit an emergency brake signal. It is by this emergency brake signal that the EOT unit is ordered to reduce the pressure within the brake pipe of the railcar at an emergency rate.
