Patent CA-2183813-A1 (CA)
Title: Statistical multiplexing
Inventor: BUDGE MICHAEL RICHARD JOSEPH
IPC: H04N21/2385
Filed: 1996-08-21
Abstract: The present invention relates to a transmitter for transmitting a plurality of digital signals through a plurality of channels, the channels having a predetermined total bitrate allocated to them, comprising a plurality of encoders one associated with each channel; a multiplexer for receiving the encoded digital signal and transmitting them as a stream of data and capable of adjusting the distribution of the bitrate allocation between the encoded signals; and processing means for providing an indication of a target quality and an actual quality for each channel and causing the multiplexer to repeatedly adjust the distribution of the bitrate allocation in response to differences between the indicated actual quality and the indicated target quality for each channel so as to tend to equalise the difference between the actual and target quality across some or all of the channels.   In principle, by grouping encoders together in what will be termed herein "statistical multiplex groups", and making real time decisions about the bitrate requirements for those encoders, bitrate can be allocated to maximise picture quality for the group. The theory is that for a variety of different picture sources in a statistical multiplex grouping, to achieve a target picture quality the bitrate requirements of each will vary with coding difficulty. Thus a channel within the statistical multiplex group that is experiencing little difficulty in encoding its picture can free bits to channels that are having greater difficulty. The effect is to smooth the picture quality and to subjectively improve it.

Patent CA-2192629-A1 (CA)
Inventor: BIELAGUS JOSEPH B
IPC: B07B11/04
Filed: 1996-12-11
Abstract: A fan draws air out of a cyclone and through an open-bottomed separation chamber at approximately seven hundred to eight hundred feet per minute. Shredded plastic bottles or other mixed particulate material is metered into the separation chamber and is evenly distributed by a grid of closely spaced narrow bars which extends into the separation chamber. The bars are cantilevered into the separation chamber and are caused to vibrate by an oscillatory mounting. The shredded material may be fed by an ordinary chute without an air lock onto the deck of the grid of bars. Air moving rapidly between the bars lifts and separates the various constituents of the shredded bottles. The denser particles fall down through the bars and are recovered as the heavy recyclable fraction. The lightweight particles including paper are drawn up through the separation chamber and into the cyclone. Dense material such as trash or other inadvertently added substances which are too large to pass through the bars is oscillated along the inclined bars to an exit chute.

Patent CA-2198157-A1 (CA)
Title: Low pressure gas vaporizer and method of operation
Inventor: KHADIM NEIL M
IPC: F02M21/06
Filed: 1997-02-21
Abstract: A fuel vaporizer and method of fuel vaporization are discribed for use with a fuel such as propane, that is know to tend to liquefy at low temperatures and to vaporize at high temperatures. The vaporizer and method described pertain to a series of internal walls and cavities which promote heat-exchange and transfers heat from a fluid engine coolant to the fuel. The transfer of heat and vaporization of fluid occurs by virtue of movement of the fuel through a series of countercurrent passages created by the walls and cavities, with increasing cross-sectional dimensions in the passages to accomodate the expansion of fuel from the liquid to the gaseous state. The heat is transferred by conduction across a metallic interface which forms part of the vaporizer and which separates the fuel from the coolant.
