Patent CA-2169111-A1 (CA)
Title: Roulette gaming machine
Inventor: FENTZ BARRY W
IPC: A63F9/24
Filed: 1996-02-08
Abstract: An electronic gaming machine that closely emulates the actions, look and feel of a live action roulette game including betting table layout, roulette wheel operation and croupier interactions with the game players is accomplished by a CRT displayed game table and a tower CRT displaying the graphic image of a roulette wheel and the video appearance and speech of the dealer.  The roulette game consists of five player stations surrounding a simulated game table consisting of two large horizontal CRT monitors which display the roulette betting field.  The game is firmware controlled from a game table chassis which communicates with each player station and with the tower video system.  Each player via a track ball and control buttons, places or deletes bets on the displayed betting field during the wagering phase.  As the game progresses announcements to the players appear on the CRT betting table and on the tower video monitor by the live video appearance of the current game dealer.  The game tower monitor displays a spinning roulette wheel, and a computer graphics overlay ball (sprite) which rotates on the roulette wheel rim, drops from the rim, bounces and eventually stops at a randomly selected winning number on the spinning roulette wheel in a manner closely emulating the operation of an actual roulette wheel.  Developed and prerecorded video graphic images from a laser disk player or from a PC hard disk drive together with computer controlled overlay graphics provides the roulette wheel, roulette ball, croupier appearance and her/his voice announcements.  Moreover, selection of one of a plurality of bounce patterns reduces repetitive ball movements during different rounds, thereby providing more realistic simulation of an actual roulette game.

Abstract: L'invention concerne un procédé et un appareil permettant la pénétration d'un tubage de puits (12) et dans les couches terrestres entourant ledit tubage. Ce procédé consiste à insérer un arbre flexible (24), pourvu d'une fraise sphérique (22) à l'une de ses extrémités, dans des tiges à refoulement (18) placées à l'intérieur d'un tubage. Les tiges à refoulement sont dotées d'un raccord coudé (20) à leur extrémité inférieure en vue de recevoir la fraise sphérique. On fait ensuite tourner l'arbre flexible, et la fraise sphérique découpe une ouverture dans le tubage du puits, puis est déplacée horizontalement sur une distance généralement inférieure à 12 pouces (30,5 cm). On retire ensuite l'arbre flexible et la fraise sphérique et on insère un tube flexible (48) pourvu d'une tête de jet (46) à ajutages à une de ses extrémités, dans les tiges à refoulement et dans le canal. On fait alors passer par pompage, un fluide constitué de tensioactifs et d'eau, sous haute pression, dans le tube, et le fluide sous haute pression traverse l'orifice du forage en spirale, creusant ainsi un prolongement dans le canal précédemment formé. On fait passer le tube, en continu, dans la voie tant que le fluide sous haute pression continue de faire sauter les couches terrestres. On creuse ensuite la canal sur une longueur présélectionnée, depuis le puits, jusqu'à 200 pieds (61 mètres) et plus.

Patent CA-2176338-A1 (CA)
Title: Corneal template and surgical procedure for refractive vision correction
Inventor: GORDON EUGENE IRVING
IPC: A61B17/30
Filed: 1995-09-12
Abstract: A method for the selective removal of corneal tissue, and change of cuvature thereof, for refractive vision correction by means of a correction template m conjunction with a planar cutting high pressure water jet micro-keratone. The correction template is adapted to provide a planar cutting guide, on the corneal tissue for the refractive correction required, with the template being shaped with a non-planar surface of predetermined configuration (related to the desired correction). The non-planar surface of the template is fitted to the area of the cornea to be refractively corrected, whereby the corneal tissue to be removed is selectively deformed so as to be substantially conformed to and held against the non-planar surface. Application of a vacuum between the template and cornea aids in this holding. The water jet micro-keratome in a sheet-like configuration provides a full non-scanning transverse planar cut through the corneal tissue at a position adjacent the template, such that release of the template from the corneal tissue results in the undeformed configuration thereof having the desired correction. Use of the water jet micro-keratome provides a cut corneal tissue surface of smoothness and polish substantially equivalent to that of the original surface.

IPC: C08L23/06
Filed: 1995-05-09
Abstract: Medium modulus, polyethylene films and bags with improved tear performance are made for heavy-duty packaging applications and hot-fill uses. Film compositions contain high molecular weight linear polyethylene and linear ethylene/.alpha.-olefin interpolymer. The film is at least about 1.25 mils (31 microns) thick and is characterized as having a calculated film density in the range of 0.923 to 0.95 grams/cubic centimeter (g/cc) and typically has a tear strength or impact resistance at least 30 percent greater than current industrial polyethylene film. The novel film has superior dimensional stability and strength properties which allow significant down-gauging relative to industrial films used as heavy-duty overwraps, sleeves and bags.
Patent CA-2192858-A1 (CA)
Title: A barrier material comprising a thermoplastic and a compatible cyclodextrin derivative
Inventor: WOOD WILLARD E
IPC: B29C48/10
Filed: 1995-05-16
Abstract: A barrier film composition can comprise a thermoplastic web comprising a thermoplastic polymer and a dispersed cyclodextrin composition having substituents that compatibilize the cyclodextrin in the film. The thermoplastic/cyclodextrin film obtains substantial barrier properties from the interaction between the substituted cyclodextrin in the film material with a permeant. The substituents on the cyclodextrin molecule cause the cyclodextrin to be dispersible and stable in the film material resulting in an extrudable thermoplastic. Such materials can be used as a single layer film material, a multilayer film material which can be coated or uncoated and can be used in structural materials wherein the thermoplastic is of substantial thickness resulting in structural stiffness. The cooperation between the cyclodextrin and the thermoplastic polymer provides barrier properties to a web wherein a permeant can be complexed or entrapped by the cyclodextrin compound and held within the film preventing the permeant from passing through the film into the interior of a film, an enclosure or container. The permeant can comprise a variety of well known materials such as moisture, aliphatic or aromatic hydrocarbons, monomer materials, off flavors, toxic compounds, etc.

Inventor: JONZA JAMES M
IPC: B32B7/023
Filed: 1995-12-19
Abstract: Birefringent optical films (10, 12, 14) have a Brewster angle (the angle at which reflectance of p-polarized light goes to zero) which is very large or is nonexistant. This allows for the construction of multilayer mirrors and polarizers whose reflectivity for p-polarized light decreases slowly with angle of incidence, are independent of angle of incidence, or increase with angle of incidence away from the normal. As a result, multilayer films (10) having high reflectivity (for both planes of polarization for any incident direction in the case of mirrors, and for the selected direction in the case of polarizers) over a wide bandwidth, can be achieved.
