Title: Filter system for a liquid stream with automatic rapid flush capability
Inventor: MOOREHEAD JACK
IPC: B01D29/66
Filed: 1994-06-22
Abstract: A system for filtering a liquid stream, typically drinking water from a natural source.  The system includes a plurality of filter stations, each of which receives at least a portion of the influent liquid flow, passes the flow through a filter and passes the filtered liquid to an affluent line.   When the filter has reached its capacity for removing particulate material from the liquid flow, preferably as determined by measurements of pressure drop across  the filter media,  a small quantity of the clean affluent liquid is passed through the filter in a reverse direction to back flush the filter media, with the flush liquid directed to a waste water line.  Back flushing can be accomplished automatically under microprocessor control, using signals from a filter media pressure sensor.  With a plurality of parallel filter arrangements, continuous flow to the affluent line is easily maintained, since the back flush cycle is short and all filter sets would not be in the back flush mode at the same time.   The filter has a porous tubular core bearing filter media on the core surface. The core is housed in a canister having an entrance directing influent liquid into the canister tangential to the core and an affluent line connected to the interior of the core.  This configuration provides improved filter media life and efficient reverse flow during back flushing.
Patent CA-2127370-A1 (CA)
Inventor: ALBERS THOMAS M
IPC: G06T11/20
Filed: 1993-01-13
Abstract: Line draw circuitry receives parameters defining first and second endpoints of a line and calculates line parameters based on the first and second endpoints. The line parameters are then stored in a memory. A "calculate-only" control signals determines whether a line is drawn immediately after calculation (and storing) of the end parameters or whether the line is drawn responsive to a subsequent "start" signal. If the line is to be drawn responsive to the start signal, the line parameters may be modified prior to drawing the line.

IPC: A63F3/04
Filed: 1994-08-09
Abstract: A game apparatus and method wherein, for a player to advance around a game board to a winning board position, the player must satisfactorily comply with instructions that solicit a rhyming response. The game board includes a starting space, a winning space, and a number of distinguishable spaces therebetween.      The spaces are divided into several categories that are distinguishable by different indicia and/or different colors. Each category of space requires a player to comply with a particular instruction. When a player occupies one category of game board space, the player must recite a word that rhymes with a word selected at random; another category of game board space requires a player to create or recite ~ multi-line rhyme, one line ending with a word selected at random, e.g., from a playing card, and the remaining lines ending with a word that rhymes with the word selected at random the last words of the remaining lines car be chosen by the player from any words, or instructions may require the player to use one or more last words from a list of rhyming words; another category of space on the game board requires a player to create or recite a multi-line greeting card message, wherein the last word of each line rhymes; another category of space on the game board requires a player to recite two multi-word lines from a literary or musical work, wherein one of the lines ends in a word that rhymes with an ending word of the other line.
Patent CA-2129861-A1 (CA)
Title: Glazing assemblies and processes for the formation thereof
Inventor: CHINZI CALOGERO
IPC: B32B17/10
Filed: 1994-08-10
Abstract: A glazing assembly is described, suitable for use as an emergency escape, comprising a laminated panel having at least two sheets (10, 12) of vitreous material adhered to a polymeric intervening layer (14) which extends continuously between said sheets (10, 12). In at least one minor area zone of the panel, the possibility of elongation of the intervening layer (14) under the influence of mechanical stress when said at least two sheets (10, 12) of vitreous material are broken, is different compared with the possibility of elongation of said intervening layer (14) over the rest of the panel. The assembly may be used in vehicles, such as in high-speed train carriages. When there is a need to break through the panel for emergency escape purposes, the panel is subjected to a suitable mechanical force, the intervening material (14) is more easily torn or cut away, thereby enabling faster escape. The invention thereby enables easy escape through a window space while maintaining the security performance of the assembly at a satisfactory level.

Patent CA-2133313-A1 (CA)
Inventor: DUFOUR MARTIAL J
IPC: G01C17/38
Filed: 1993-03-30
Abstract: Automatic correction of hard-iron and soft-iron distortion in a magnetic compass is achieved by storing a set of measured magnetic field values for different discrete directions of the compass relative to an estimated origin. Values are interpolated for the directions not yet measured to provide a set of measured and interpolated values defining a substantially eliptical locus of the sensed magnetic field vector (ET). New coordinates for the estimated origin are derived and the measured values are adjusted to take account of changes in the estimated origin. The heading is corrected for displacement of the origin due to hard-iron effect and for ellipticity of the locus due to soft-iron effects.
Patent CA-2134538-A1 (CA)
Inventor: SIEMON JOHN A
IPC: H01R13/6471
Filed: 1994-10-27
Abstract: Abstract of the Invention: The field terminable patch connector of the present invention comprises three separable upper and lower body or housing portions, all three of which have mutual interlocking detent structures which permit the three housing portions to be assembled and locked together into a rigid assembly. One of the three housing portions is a contact insulator which has a multiplicity of slots and protrusions capable of retaining contacts for receiving conductors of a twisted pair cable. In addition, a metal shield is provided which fits between both the upper housing portion and contact insulator portion. This metal shield portion shields (e.g., electrically isolates) pairs of conductors from one another and is held in position by the same aforementioned detents. When properly field terminated and used with a Category 5 compliant cable, the patch connector of the present invention meets or exceeds the TIA/EIA TSB-40 Category 5 transmission requirements when mated with 110 type connector blocks. Other features of this invention include the ease of field assembly without special tools or operations (e.g. soldering or crimp tools), polarization structure which assures proper orientation of the mating conductors, a snap detent structure that provides a positive and stable mechanical connection to the connecting block, and an improved insulation displacement terminal which preferably utilizes closed gap construction and low surface area mating contacts that minimize capacitive coupling between adjacent contact positions to assure Category 5 compliance. The patch connector of the present invention utilizes a novel shield construction that not only provides crosstalk isolation between conductor pairs, but is also designed to allow access on either its outer surface or its inner surface, or both when mated with an appropriate shield connection means on the plug receptacle. This novel structure provides shield connections between cables with inherently low transfer impedance and therefore assures high frequency shield effectiveness. Another important feature of the present invention is the ability to pull wire pairs into their respective positions in the patch cover. Once the cable jacket is secured in the cover, wire pairs may be pulled into their respective location. The cover includes features that separate the tip and ring conductors and urge them outward and into their respective IDC termination slots. Once all pairs arepositioned, the excess length of insulated wires are accessible on all sides, such that they may be trimmed prior to termination. The present invention also provides shield means for 110-type termination blocks to assure that shield integrity is maintained between cables and that shield elements are connected before signal conductors of the plug and socket connectors are allowed to touch and are disconnected after plug and socket signal connections are broken.
