Patent CA-2174092-A1 (CA)
Inventor: RUSSO ANTHONY
IPC: E21F17/16
Filed: 1994-10-12
Abstract: Cette invention concerne des cavernes et des procédés de production de cavernes dans des dômes de sel stratifiés. Selon un procédé préféré on fore un premier trou de forage (19) dans la formation saline (10) et on lixivie dans cette dernière (10) une cavité (13) destinée à recevoir des matières insolubles. On fore ensuite, à une certaine distance de premier trou de forage (19), un deuxième trou de forage (17) en direction de la formation saline. La foreuse effectue son travail dans la formation saline selon une direction horizontale jusqu'à ce qu'elle rencontre la cavité (13) destinée à recevoir des matières insolubles. Ceci produit un conduit sensiblement horizontal (20) par lequel on envoie de manière régulée du solvant dans la formation saline environnante, ce solvant lixivie le sel et produit une saumure concentrée qu'on extrait par le premier trou de forage (19). Les matières insolubles s'accumulent dans la cavité (13) prévue à cet effet. Le fait d'envoyer le solvant de manière régulée permet de produire une caverne horizontale d'où partent deux trous de forage (17 et 19).

Title: Optical polarizer
Inventor: OUDERKIRK ANDREW J
IPC: B32B7/023
Filed: 1994-12-20
Abstract: A reflective polarizer and a dichroic polarizer are combined to provide an improved optical polarizer. The dichroic and reflective polarizers are typically in close proximity to each other, and are preferably bonded together to eliminate the air gap between the polarizers. The combination of the two polarizers provides a high reflectivity of one polarization and high transmission for the perpendicular polarization from the reflective polarizer side of the combined polarizer, and high absorption and transmission for light of orthogonal polarization from the dichroic polarizer side. The combination also reduces iridescence as seen in transmission and when viewed in reflection from the dichroic polarizer side. The increased extinction ratio and low reflectivity of the optical polarizer allows use of a lower extinction ratio dichroic polarizer in applications requiring a given extinction ratio and high transmission.

Abstract: Methods for preparing an ink concentrate are disclosed.  To prepare the ink concentrate, a varnish that includes at least one dispersing polymer is added to the pigment particles, such as an aqueous slurry or an organic- solvent-treated aqueous slurry of the pigment particles.   The blend of varnish and pigment particles then is heated to a temperature effective to melt the dispersing polymer.  Upon cooling, the dispersing polymer solidifies at the surface of the pigment particles  to thereby physically attach and bond to and preferably encapsulate the pigment particles and form an ink concentrate.   The ink concentrate thus  formed will have improved color properties as compared to conventional ink concentrates.
Patent CA-2189935-A1 (CA)
Title: Floor covering hot-melt seam sealing method and product
Inventor: ESHLEMAN J MICHAEL
IPC: A47G27/04
Filed: 1996-11-08
Abstract: A method is disclosed for sealing and bonding the seams and edges of resilient and other types of floors, whereby specially formulated hot-melt sealants/adhesives are applied in molten form at the flooring installation site using a heated gun equipped with a specially designed tip.  The hot-melt sealant/adhesive flows into and completely fills the seam and bonds to the edges of the flooring producing a bead of material that extends above the surface of the flooring.          The specially designed tip facilitates this process by guiding along easily in the groove of the seam or joint and directing the molten sealant/adhesive accurately into the seam. The tip allows the seam or joint width to be very narrow and enhances sealing and adhesion by imparting heat to the edges of the flooring material.  Upon cooling, a spatula knife or other appropriate tool is used to skive off the excess bead of material leaving it flush with the flooring.  The appropriately pigmented sealant/adhesive produces an appearance that is barely noticeable from the surrounding floor.

Title: Optical random access memory having folded image
Inventor: RUSSELL JAMES T
IPC: G11C11/56
Filed: 1995-04-13
Abstract: A compact optical memory (100) in which data is stored in an optical data layer (100) capable of selectively altering light such as by changeable transmissivity, reflectivity, polarization, and/or phase. The data is illuminated by controllable light sources (106) and an array of multi-surface diffractive imaging lenslets causing a data image to be projected onto an array of light sensors (108) by reflecting, hence folding the image rays, by means of a mirror (128) that both reflects and optically modifies the light rays to redirect them onto the sensor array (108) located substantially coplanar with the data layer. Data is organized into an annular array of patches (called pages). By selective illumination of each data page, one of the lenslets images the selected data page onto a central image plane where the sensor array (108) is located. Light in the data image pattern strikes different ones of the arrayed light sources, thereby outputting a pattern of binary bits in the form of electrical data signals.

The lower surface together with opposed inner surfaces of the sides form a downwardly depending air entrapment chamber extending longitudinally beneath the lower surface. The chamber is reactiveto provide substantial surface effect ram air lifting force on the vehiclein response to forward motion of the vehicle. In addition, the vehicle includes an airfoil spaced above and interconnected with the vehicle body to provide substantial out of surface effect lifting force on the vehiclein response to such forward motion. Further the vehicle includes aerodynamic vertical stabilizing means, preferably vertical stabilizers serving not only to provide vertical stabilization but also to interconnect the airfoil with the vehicle body. Additional stabilization may be achieved by the provision of opposed stabilizing sides each extending longitudinally forward from a corresponding one of the vertical stabilizers and downwardly from a corresponding end of the airfoil. Such stabilizing sides together with a lower surface of the airfoil form a longitudinally extending, downwardly depending, air channel above the upper surface of the deck. In a preferred embodiment, the vehicle body includes a pair of pontoons to provide flotation in water. Each pontoon may include an intermediate bottom portion which sits lowermost when the vehicle is idly afloat, a forward bottom portion which extends upwardly and forwardly from the intermediate portion, and an elongated rearward bottom portion which extends upwardly and rearwardly from the intermediate portion.

IPC: B31B23/00
Filed: 1997-09-29
Abstract: In a winder for winding webs from a bag-making machine into rolls, a winding turret mounts four winding spindles, each having a web-winding portion and a pulley-mounting portion, which mounts a conjointly rotatable pulley and an independently rotatable pulley. A first timing belt and a second timing belt are arranged to be independently driven. The winding turret is indexable so that, in any indexed position, a first timing belt interengages the conjointly rotatable pulley mounted on the given winding spindle and interengages the independently rotatable pulley mounted on the next winding spindle and a second timing belt interengages the independently rotatable pulley mounted on the given winding spindle and interengages the conjointly rotatable pulley mounted on the next winding spindle. The rotational speeds of a motor driving a given winding spindle, whichever is being used to complete winding of a roll, and the rotational speed of a motor driving a web conveyor are measured. The motor driving the same winding spindle is adjusted so as to maintain a generally constant winding tension on a web being wound. A pair of infeeding rollers and a pair of separating rollers are operated so as to apply a generally constant winding tension to a web, except during intervals during which the surface speed of the separating rollers exceeds the surface speed of the infeeding rollers so as to separate the web at cross perforations.

Title: Method and apparatus for baling loose materials
Inventor: ROBINSON LONNIE R
IPC: B30B9/30
Filed: 1996-03-28
Abstract: A method of the apparatus for baling loose materials, such as waste material, includes a controllably moveable door assembly. In one embodiment, the door is adapted to open from an initial position to a final position such that the compacted bale can be ejected from the compaction chamber through the opening defined by the open door. In this embodiment, the leading edge portion of the door is moved to a final position in general alignment with the compacting ram platen such that bales of various sizes, including oversized bales, can be readily ejected from the baling apparatus. For example, the leading edge portion of the door can be moved into alignment with or rearward of the compacting ram platen. In another embodiment, the baling apparatus operates in a plug bale mode and includes a door which is urged against an at least partially ejected bale so as to securely hold the plug bale within the opening defined to the compaction chamber during the compaction of a succeeding bale. In particular, the door is partially closed until the speed with which the door is being closed is less than a predetermined speed. Once the speed with which the door is being falls below the predetermined speed, further closure of the door is halted and the plug bale is securely held within the opening due to the increased frictional forces provided by the partially closed door.
