Patent CA-2252938-A1 (CA)
Title: Apparatus for cutting and rolling sheet material
Inventor: DUECK RAYMOND
IPC: B65H16/02
Filed: 1998-11-05
Abstract: The apparatus for cutting sheet material includes a table in which the sheet material is rolled onto by a unrolling cradle. A re-rolling cradle at a respective side of the table rolls the cut material. An arrangement on the cradles ensures an even roll when unrolling and re-rolling. The re-rolling cradle has a pivotal adjustment about a vertical axis for receiving the material. A measuring arrangement on the apparatus measures the length of sheet to cut at a desired length. The measuring arrangement is automatically calibrated using spaced detectors.

Patent CA-2265227-A1 (CA)
Inventor: LYONS ARTHUR P
IPC: B60L9/18
Filed: 1999-03-11
Abstract: A controller (400) for a variable-speed induction motor (498) includes field-oriented control (410, 476), which in a feedback (402) arrangement senses motor parameters to form field and torque error signals. The field error signals are processed by a first limited-state PI processor (490a), which individually limits the magnitude of the proportional component of the field voltage to no greater than the bus voltage. The field error signals are also processed by a state-limited integrator (426a) which limits the integral component of the field voltage to the difference between the proportional component and the bus voltage. A first summer (432a) sums the proportional and integral components to make the field voltage command.  The torque error signals are processed by a further limited-state PI processor (490b) which individually limits the proportional component of the torque voltage to a value not greater than the available bus voltage, after the first PI processor has been given preference. The integral component of the torque voltage command is generated by a second state-limited integrator (426b) which limits the integral component of the torque voltage command so that the torque voltage command does not exceed the available bus voltage. A second summing circuit (432b) sums the proportional and integral components of the torque voltage command. The field and torque voltage commands are processed to produce the desired motor flux and torque, and a feedback loop forces the motor current to follow the commanded values.

IPC: E04H15/48
Filed: 1999-09-23
Abstract: A portable folding shelter has a fixed central frame plus two outboard wing frames which are parallel to and pivotable relative to the central frame. A flexible, weatherproof membrane extends across the central frame and the wing frames when the latter have been folder outward, thereby sheltering the area beneath the frames and membrane.  Outrigger arms support the frames on the ground surface, and have wheels allowing the shelter to moved across the ground. Jacking mechanisms are provided to assist in assembling and disassembling the shelter, as well as in loading and unloading the shelter from a flatbed trailer. When assembled, the shelter sits high enough to permit a flatbed trailer to pass underneath its framework. Accordingly, the shelter may be transported on a trailer to a desired location and there assembled, whereupon the trailer may be withdrawn. When dissassembly and transport of the shelter are desired, a trailer may be backed under the framework of the shelter, whereupon the shelter may be disassembled and loaded onto the trailer.
