Patent CA-2141115-A1 (CA)
Title: Computerized system for simulating paper sheet formation and the appearance of print thereon
Inventor: DANBY ROGER
IPC: G06T11/00
Filed: 1995-01-25
Abstract: To provide a simulation of the formation of a sheet of paper and the appearance of print thereon, a computerized system is adapted to receive input parameters related to a type of  headbox stock desired, the fabric upon which the paper is to be formed, the paper machine to be used, and the printing process desired. Data relating to the actual production of paper is configured to simulate a series of fibres being dropped onto the surface of the fabric to create a mat.  After a sufficient amount of fibre has been simulated as being dropped onto the fabric creating a fibrous mat, the system will indicate a final sheet has been com-pleted when it has the desired basis weight as initially inputted by the user.  After a final sheet of paper is deemed finished a report pertaining to sheet characteristics is generated.   The report provides the user with data relating to fibre retention, a display of the simulated sheet along with its density varia-tions,  surface characteristics,  and structure.  The system, adapted to accept data relating to the type of printing process, configures such data with that already inputted, so as to provide a simulation of ink printing on the simulated sheet.  The user thus has a visual output representative of the quality that a final physical sheet of paper would possess after manufacture and printing thereon.
Patent CA-2141264-A1 (CA)
Title: Device for the swiveling movement of a sheet, in particular in refrigeration counters or merchandise counters
Inventor: STENEMANN BRUNO
IPC: A47F3/00
Filed: 1995-01-27
Abstract: The invention is directed to a device for the swiveling movement of a sheet. A stationary bearing part supports an articulated part in a swivelable manner.  The articulated part supports the sheet and is movable about a substantially horizontal swivel axis. The sheet is accordingly movable between a lowered position and a raised position, the direction of this movement being determined by a vertical swiveling plane. Energy accumulators, e.g., pneumatic springs, serve as auxiliary lifting means for raising the sheet.  These energy accumulators have two connection ends which are loaded in opposite directions and determine the effective direction of force of the energy accumulator. For the purpose of an advantageous arrangement of the device which economizes on space, it is proposed that the energy accumulator be arranged with its effective direction of force substantially transverse to the swiveling plane of the sheet. The two connection ends of the energy accumulator are constructed as three-dimensionally acting rolling joints.

Patent CA-2151067-A1 (CA)
Inventor: HORST GARY E
IPC: H02P25/08
Filed: 1995-06-06
Abstract: A control circuit (10) for controlling the residual or tail current decay in a single phase or polyphase SRM winding when a phase is switched from active to inactive.  A Hall-effect type sensor (30) senses rotor position of the SRM.  Current flows through a winding (W) of the motor when the motor phase winding is active; and, current flow into the winding decays to zero when the phase becomes inactive. Semiconductor switches (22) direct current flow into the winding when the phase is active and then redirect residual energy in the winding between an energy recovery circuit and an energy dissipation circuit when the phase becomes inactive.          A PWM signal generator (44) provides PWM operating signals to the switches to control current flow first into the winding and then between the recovery and dissipation circuits.  A control module (42), or microprocessor (52) with a PWM output, is responsive to rotor position information for controlling operation of the PWM signal generator.  The signal generator provides PWM signals having one set of signal characteristics when there is current flow to the winding and a different set of characteristics when there is not.          This produces alternate intervals of zero voltage and forced commutation residual current decay while the phase is inactive.          During the decay interval, both the PWM frequency and pulse duty cycle are variable to produce a current decay scheme which eliminates ringing and motor noise

Title: Apparatus and method for reducing particulate emissions from combustion processes
Inventor: GOODSON DAVID B
IPC: F01N3/01
Filed: 1995-06-15
Abstract: A high voltage electrical potential is passed through a combustion flame (226) to agglomerate particles, which are then removed from the exhaust gases through combustion or deposition on nearby surfaces of the apparatus. The electrode (240) has electrically connected thereto an electrode connector (244) that extends through, but is electrically insulated from, baffle wall roof portion (234) and wood stove roof section (212) to a voltage source (not shown). Alternatively, electrical connection may be made to a portin of tube (250) that extends outside the stove. Grate (220) is electrically grounded. Thus, an electrical field is produced in the region between the electrode (240) and the grounded grate (220). Application of the high voltage electrical potential and secondary air dramatically reduces particle emissions produced by the wood stove.

Title: Vehicle brake
Inventor: SIEGRIST ERIC
IPC: F16D53/00
Filed: 1996-02-26
Abstract: The brake system employs a ring braking member and a suspended brake caliper having a responsive linkage correcting the caliper and a knuckle support arrangement.      The ring braking member is preferably die cast as a single component with a control hub and is of a lightweight, high strength, high temperature aluminum composite material.      The brake system is designed to have a relatively thick ring brake member of this lightweight material to provide sufficient capacity to absorb the heat of braking and transfer of this heat to the surrounding air prior to the ring brake reaching a temperature where damage is likely to occur. The normal operating temperature is well below the theoretical maximum temperature or rated temperature of the composite material.

Title: Compound geometry rail switch
Inventor: WILLOW ROBERT E
IPC: E01B7/00
Filed: 1994-08-29
Abstract: An improved geometry for a split switch turnout with a compound point rail (41) leading to a curved closure rail (42) that is linear and tangent through the switch frog (44). The switch point rail (41) includes a proximal curved portion (47) having the same radius as the closure rail (42), and a distal end portion (46) that is linear and tangent to the proximal portion (47). The linear distal end portion (46) of the point rail (41) provides an entry angle of the switch point that is the same as the angle of attack of the wheel truck encountering the turnout, and also provides the shortest possible switch point length and the greatest possible radius of curvature of the closure rail (42). The angle of attack and the curvature of the closure rail (42) can be optimized to produce a split switch turnout that permits high speed through the turnout while minimizing wear and maintenance costs.
