Title: Method and computer product for managing database driven insertion and mail piece tracking data
Inventor: MACKELPRANG MARK G
IPC: G07B17/00
Filed: 1999-07-14
Abstract: A client/server architecture for database driven insertion and mail piece tracking system, method, and computer program product is disclosed. A database is populated with database driven insertion data comprising instructions for handling mailpiece material. A server manages the database by responding to requests for mail processing instructions from clients and storing mailpiece data received from clients. A scanning device reads key code marked mailpiece material in which the key code corresponds to a database location containing instructions for handling mailpiece material. A client processor receives the key code from the scanning device, and transmits a request to the server for accessing the database location containing the instructions for handling mailpiece material. The server retrieves the instructions for handling mailpiece material, and transmits the instructions to the client. The client causes the performance of a mail processing task in accordance with the instructions, gathers mailpiece tracking data as the mailpiece material is processed, and forwards mailpiece tracking data to the server. The database information is accessible to report writing and generating software applications which cull data pertaining to a given mail processing job into a desired format.
Patent CA-2347942-A1 (CA)
Inventor: SARUWATARI KEVIN
IPC: F16D65/28
Filed: 2001-05-22
Abstract: A relatively simple hydraulically operated disc brake mechanism for drive systems which store torsion by reason of being under torque is disclosed. Certain drive systems such as the drive strings for deep well submersible pumps store considerable torsion due to torque and elasticity. Such torsion must be controllably released if drive power is interrupted. The disc brake mechanism includes a housing that defines a reservoir for lubricating oil for the bearings of a shaft that drives a bi-directional hydraulic pump. When the shaft turns in an operating direction, the pump conveys the lubricating oil in a closed circuit by way of a control manifold through the brake mechanism and back to the reservoir, without activating the brake mechanism. This flushes the complete lubricating oil circuit including the control manifold and the brake mechanism to prevent accumulation of gas pockets therein at locations of little or no fluid flow. If normal operation is interrupted and the reactive torque in the system is released, the bi-directional pump forces oil through the control manifold to a disc brake caliper of the brake mechanism while controlling oil flow through the brake mechanism, which activates the brake mechanism to brake a disc rotor attached to the shaft. The faster the shaft turns as it releases reactive torque, the more braking force applied. As torsion is released, pump speed drops and brake force is correspondingly reduced until all torsion is released from the drive string permitting safe handling and soft restart of the drive string. The advantage is much improved safety and a self-regulating brake mechanism that handles power interruptions without manual intervention and is no longer prone to brake fade.

Inventor: ANDERSON GEORGE
IPC: B67D1/00
Filed: 2001-05-28
Abstract: A beverage dispense stanchion has an illuminated display unit which in turn includes a light guide with at least one connected light source. The light guide is operable to distribute light from the light source to enhance the display. The light guide is a decorative photoconductive body having a display surface and an edge into which the light source is fitted to illuminate the photoconductive body. The light source is a light emitting diode that is optically coupled into the edge, to diffuse light through the photoconductive body and thereby provide indirect lighting of the display surface.   At least some non-display surface portion of the photoconductive body is adapted to reflect light back into the photoconductive body. The stanchion includes a carcass adapted for removable mounting of the illuminated display thereon, and ones of a plurality of interchangeable illuminated displays are adapted to be selectively mounted/removed from the carcass from time to time.

Title: Systems and methods for passive pressure-compensation for acoustic transducers
Inventor: FLOOR JAMES W
IPC: H04R9/00
Filed: 2000-03-10
Abstract: Systems and methods of the invention can equalize the pressure between an interior cavity and an environment exterior to the interior cavity, while providing for acoustic isolation between the two environments so that acoustic energy propagating through one environment does not cause acoustic vibrations in the other environment. In one application, these pressure compensation systems are employed to equalize the pressure on either side of a moving coil projector, thereby reducing the deleterious effect that a pressure differential across the moving coil projector can have on the operation of the moving coil projector and reducing the likelihood that propagating acoustic energy can result in phase cancellation that reduces the acoustic performance of the moving coil projector.
