IPC: A01D34/73
Filed: 1993-12-09
Abstract: ABSTRACT OF THE DISCLOSURE A cutting attachment for use with a vegetation cutting device.  The cutting attachment has a body with a generally planar coupling portion and a central axis of rotation.  In one embodiment, the body further includes a conical central wall portion extending radially outwardly and in a first direction from the coupling portion and the axis and a circular outer wall portion adjoining the central wall portion and extending generally radially outwardly therefrom.  The central wall portion defines a conically-shaped self-cleaning inner cavity disposed symmetrically about the axis.  The outer wall portion has a generally smooth outer surface which serves as a skid plate.  An outer self-cleaning cavity is formed by an outer surface of the central wall portion and an inner surface of the outer wall portion.  A coupling assembly, which can include an adapter having first and second clamping elements, is carried by the coupling portion for coupling the body to the cutting device to cause rotation about the axis.  A plurality of spaced apart radially extending cutting elements, in the form of cutting blades and/or cutting strings, are carried by the body.  Cutting blades are provided with aerodynamic configurations, serrated edges, inner and outer cutting edges and arms for securing the blades to the cutting attachment which permit longitudinal movement of the cutting blade with respect to the cutting attachment.  Cutting strings are provided with inner and outer cutting portions, grooves for reducing fraying and a spiraled configuration.

Title: Bioassay method
Inventor: PRATTEN MARGARET K
IPC: C12M1/34
Filed: 1992-07-03
Abstract: A bioassay method comprises passing test reagents into the circulation of an embryo in such manner that the reagents are not modified by any intermediate metabolism. This can be effected in e.g.  rat embryos by microcannulation directly into the vitelline circulation by passing the visceral yolk sac. In chick embryos the test reagent can be administered directly into the extra-embryonic circulation. The embryo is cultured and assessed as to its embryonic development.

Title: Combined Product Shipping and Display Box
Inventor: EDGERTON ERIC JR
IPC: B65D5/4805
Filed: 1994-10-11
Abstract: A combined shipping and display box is provided which is formed from a one-piece blank of box-board material configured such that, when erected, the box will include bottom, front and rear walls as well as an opposed pair of side walls.  The side walls are each formed from respective side panels having a central sub-panel and a pair of divider sub-panels extending in opposite directions from the central sub-panel.  These divider sub-panels are inwardly foldable onto their respective central sub-panel along predetermined fold lines so as to not only be positioned in adjacent contact with the central sub-panel, but also to establish protruding interior dividers for the shipping/display box.  When erected, therefore, the terminal edges of each respective pair of divider sub-panels will abut one another such that each of the interior dividers is paired with a similar interior divider associated with the opposite side wall.  In such a manner, therefore, the paired dividers will establish box positions adapted to hold a selected number of prepackaged product containers in a desired array.  The dividers, moreover, protect the prepackaged product containers held thereby against movement (and hence potential damage) during shipping.

Title: Routing multiple telephone calls using a common routing plan
Inventor: FELDMAN JEFFREY
IPC: H04Q3/42
Filed: 1994-04-25
Abstract: Abstract ROUTING MULTIPLE TELEPHONE CALLS    USING A COMMON ROUTING PLAN   Multiple special service numbers, such as 800 numbers, that are owned by a customer are routed using a single, common routing plan. An 800 number database system which provides routing information for 800 number calls is configured to compare a dialed 800 telephone number received from a telephone switching system with telephone numbers stored in the database memory. Corresponding to each of the stored telephone numbers and stored within the database memory is a pointer to a routing plan to be used in processing and routing calls placed to the respective telephone number. Upon finding a match between the dialed 800 telephone number and a stored telephone number, the 800 number database provides an indication of the appropriate routing plan to be used to route the dialed 800 telephone number. The 800 database then determines from the selected routing plan how to route the call.

Title: Self-tuning tracking controller for permanent-magnet synchronous motors
Inventor: TAYLOR DAVID G
IPC: H02P6/06
Filed: 1994-08-09
Abstract: ABSTRACT A self-tuning tracking controller for permanent-magnet synchronous motors is disclosed, providing for velocity or position trajectory tracking even when both the electrical and mechanical parameters of the motor, amplifier, and load are initially unknown. A time-scale simplification of a full-order mathematical model of the motor leads to a discrete-time design model that is reduced-order and that evolves in a mechanical time-scale which is substantially slower than the electrical time-scale, permitting implementation of the self-tuning tracking controller with a lower sampling frequency (and at a lower cost) than is typically expected. A piecewise-linear parameterization of the motor torque-angle characteristic functions allows for identification of higher-order harmonics with a degree of accuracy which is selectable by the user, without requiring more computation than traditional single-term sinusoidal descriptions. Excellent performance is achieved, even with very poor initial motor parameter knowledge.

Patent CA-2144478-A1 (CA)
Inventor: DE BUDA ERIC
IPC: G01B17/06
Filed: 1995-03-13
Abstract: A device and method for monitoring the angular displacement of a rotating shaft provides an ultrasonic transceiver reflecting pulses off of a reflecting edge of a vane of a rotor affixed to the shaft. The reflecting edge is configured in the profile of an involute curve so that changes in the time delay between transmission and reception of each reflected pulse, which correspond to changes in the distance between the transceiver and the reflecting edge, are linearly related to changes in the angular displacement of the shaft, and arranged such that the reflecting edge is normal to the probe axis so that the energy is reflected back to the probe. A circular disc may be associated with the vane to provide a reference reflected pulse, which eliminates errors which might occur due to wobbling of the shaft.

Filed: 1995-04-04
Abstract: A composite check valve and positively closing electromagnetic solenoid valve, particularly such a valve for regulating the introduction of secondary air into the exhaust stream of an internal combustion engine at selected times during the operation of the engine.  The valve comprises an inlet port, an outlet port, a first valve element movable between open and closed positions for nominally regulating the flow of a fluid between the inlet and outlet ports, and an electromagnetic solenoid having a closure element for overriding the first element.  The rigid disk or closure element can function by seating against the same seat as the first element, or by "latching" the first element in its closed position. The disclosed embodiment is a flap valve which is modified by superimposing a rigid, movable valve disk over the flap.  The rigid disk is connected to the solenoid armature and is movable between an override (closed) position and a disengaged (open) position when the solenoid is energized.  The rigid disk may also limit the opening of the flap to regulate the rate of fluid flow through the valve.
