Patent CA-2200405-C (CA)
Inventor: LONDON EUGENE J
IPC: A23L1/00
Filed: 1997-03-19
Granted: 2004-07-06
Abstract: A processing apparatus, conveyor and method for processing products or materials, such as food processing equipment or methods, is configured such that the conveyor travels in a generally helical path within a processing chamber to expose products on the conveyor to a gaseous processing media such as heated or cooled air.  The conveyor includes gas flow compensation including a plurality of gas flow compensation members which partially block a portion of the surface of the conveyor, preferably toward the exterior of the conveyor in the helical path, to deflect or direct more of the gaseous food processing media away from the less densely distributed products or materials at the exterior of the conveyor caused when the conveyor follows the helical path. The processing media is thus preferably forced in the direction of the more densely distributed products toward the interior of conveyor to uniformly expose product on the conveyor to the processing media. Alternatively, the flow compensation members may be configured to direct the flow of the processing media in other predetermined paths, such as counter to the travel direction of the conveyor.

Title: Optical fibre transmission systems
Inventor: ROBERTS KIM BYRON
IPC: H04B10/18
Filed: 1997-06-05
Granted: 2005-04-05
Abstract: An optical transmission system includes means for measuring optical dispersion in the optical path, and a controllable element such as a dispersion compensator, operable in dependence on the measured value of dispersion. A low frequency dither on the optical signal causes timing jitter which varies according to the dispersion in the optical path. The timing jitter is extracted from a clock signal recovered from the optical signal. This jitter is correlated with the original dither to remove jitter effects caused by other mechanisms.      Thus a value for dispersion is derived which can be used for monitoring or control purposes.

Title: Miniature mixed gas refrigeration system
Inventor: RADEBAUGH RAY
IPC: F25B9/00
Filed: 1996-10-09
Granted: 2004-12-07
Abstract: A miniature mixed gas refrigeration system is disclosed, having a coaxial catheter (18) with an inner high pressure supply lumen (24) and an outer low pressure return lumen (22). The gas mixture is pressurized by a compressor (12) to a pressure less than 420 psia, for safety reasons. The distal portion (23) of the outer lumen contains a micro- miniature heat exchanger (28) constructed of laminated plates or sheets (42). The plates or sheets (42) establish high pressure (36) and l ow pressure passageways (40), with high surface area, having a tortuous path for the gas flow to maximize heat exchange. The high pressur e outlet (50) of the heat exchanger (28) is connected to a Joule-Thomson expansion element (30) where the high pressure gas is expanded isenthalpically to a lower temperature at least as low as 180K. This low temperature gas cools a heat transfer element (32) mounted in the outer wall of the catheter, to cool an external object. Return gas flows back through the heat exchanger to pre-cool the incoming hi gh pressure gas mixture.

Abstract: A flush toilet, for example, for use in a recreational vehicle comprises two main plastic mouldings, one of which includes the toilet bowl and the other of which forms a "shell" or outer housing in which the bowl is supported so that the bowl outlet is located in an internal space defined by the shell. In accordance with the invention, the toilet is provided with a flushing mechanism that includes a bowl rinse nozzle adjacent the rim of the bowl and an internal rinse nozzle for rinsing the walls of the internal space and flushing mechanism within the outer shell. This reduces the risk of odours developing from contamination of the shell and also means that the shell is relatively clean inside in the event that servicing of the toilet is required.

Abstract: A call selection process in a call center is configured to utilize a continuum of skill levels, in one or more categories, for a given multi-skill agent. In an illustrative embodiment, categories of levels are associated with skills supported by the given agent, with each of the categories including a level, e.g., a numerical value, for each of the skills. The levels are used in a call selection computation that determines which of a number of waiting calls should be delivered to the agent. The categories may include, for example, a speed category including levels indicative of the speed at which the agent can process calls for each of the corresponding skills, a yield category including levels indicative of results likely to be obtainable by the agent for each of the corresponding skills, and a preference category including levels indicative of preferences of the agent for calls requiring each of the corresponding skills. The process may involve selecting different subsets of one or more of the categories in a given set of categories for use at different times, depending on factors such as call volume. The call selection computation may involve, for example, computing a value for each of the skills, as a function of the corresponding level or levels and a wait time measure, e.g., a current wait time, a predicted wait time, or a ratio of predicted wait time to a service objective, for a call in a corresponding skill queue.

Abstract: Broad wavelength tuning range are achieved in an effectively reset-free, optical, automatic polarization controller by providing a device and method for varying the polarization of an input beam of light. A block of electro-optic material has two pairs of electrodes for applying a voltage across the block. Light is launched into an input end of the block for receiving the input beam of light. A controller controls a quadrature voltage applied to the first and a second pair of electrodes; the quadrature voltage has the form of a magnitude and an angle. The quadrature voltage can be varied in such a manner as to orient a given electric field within the electro-optic material through a plurality of angles, for example between 0 and 2.pi. radians; the magnitude of the quadrature voltage can be set to create an arbitrary retardance from 0 to 2.pi.. Any output polarization state can be realized by appropriately varying the magnitude and angle of the voltage applied to the Vx and Vy electrodes.
