Title: Siloxane-modified adhesive/adherend systems
Inventor: HULL COLIN G
IPC: B32B7/12
Filed: 1997-05-05
Abstract: Adhesive/adherend systems {10) of this invention comprise a siloxane-modified adhesive component (14) and a siloxane-modified adherend component (12, 16). The siloxane-modified adhesive component (14) is prepared by combining an epoxy resin with an organosilane ingredient, a polysiloxane resin, an amine hardener, an organometallic catalyst, a base catalyst, and any thickener and extender pigment. The siloxane-modified adherend component (12, 16) is prepared using a polysiloxane resin and may also contain other resins suc as epoxy, phenolic, polyester, vinyl ester, polyurethane, polyamide, melamine, furan, acrylate, thermoplastic polyvinyl chloride, polyethylene, polycarbonate, ABS, polystyrene, ethylene vinyl acetate, polyvinyl acetate, polyamide, and polypropylene resins. When placed into contact with one another, the siloxane groups in the siloxane-modified adhesive (14) and siloxane-modified adherend components (12, 16) form Si-O-Si bonds between themselves to form an attachment force that both occurs at ambient temperature within a reasonable amount of time, and that is greater than otherwise possible using adhesive/adherend systems having unmodified adhesive and/or adherend components.
Patent CA-2255066-A1 (CA)
Inventor: PIKE RUSSELL
IPC: A63F1/00
Filed: 1997-05-22
Abstract: This invention provides a side bet opportunity (22) during the play of a Twenty-One game, with the hope of receiving winnings when certain predetermined card configurations (12a-12e) are received. Upon receipt of these defined card configurations, the player is immediately paid winnings (32) during the process of the Twenty-One game. These additional winnings are based on sequences of cards, and all of the predetermined card configurations are preferably chosen such that they will not interfere with the underlying Twenty-One game. As a basis for paying out winnings, it is required that the player consecutively receives these certain card configurations after having made a bet in expectation of those card configurations appearing. Also, the final configuration of the Twenty-One hand is irrelevant to the side bet game as the players win immediately when the predetermined configurations are received, long before completion of the hand (34).
Patent CA-2258387-A1 (CA)
Inventor: LI ZHIQING
IPC: D21C9/00
Filed: 1999-01-06
Abstract: A process for the removal of transition metal ions from wood fiber slurries (cellulose pulp, including mechanical and chemical pulps), such as manganese, applies a pulse of solution containing beneficial metal ions, such as magnesium, chelant, or ion exchange chemical (or acid at a pH between about 1-4) through a pulp mat or pad. This leads to an efficient removal of manganese and a good retention of magnesium in pulp fibers at a magnesium sulfate charge as low as about 1 % (on pulp).      Results from subsequent peroxide bleaching show that the MgSO4 eluted pulp has a similar bleaching performance as that of the conventional DTPA chelated pulp. More efficient removal of manganese from pulp fibers can be achieved when DTPA chelation is performed by applying a pulse of DTPA solution through a pulp pad or mat compared to that of a conventional chelation stage.

Patent CA-2261141-A1 (CA)
Title: Coherent signal processing for cdma communication system
Inventor: ZEHAVI EPHRAIM
IPC: H04B1/69
Filed: 1997-07-29
Abstract: A variable rate communication incorporating coherent signal processing and combining is described. Within the receive system (100, 102 and 106), vectors of in-phase and quadrature-phase Walsh correlator output values (W(i)I and W(i)Q) are generated for each Rake finger over each Walsh symbol period. Inphase and quadrature-phase reference values (R(i)I and R(i)Q) are generated for each of the Rake fingers by combining the in-phase and quadrature-phase correlator outputs of the most likely Walsh symbols over a series of Walsh symbol periods. The most likely Walsh symbols are determined on a symbol-by-symbol basis by summing the Walsh correlator output energies from each finger and selecting the largest. The vectors of in-phase and quadrature-phase values are then projected (116) on the in-phase and quadrature-phase reference values and weighted by the reference amplitude. The vectors of projected and weighted values are summed via coherently combining (118), and the corresponding values from the other Rake fingers used to obtain a resultant vector of coherently demodulated Walsh correlator outputs (120). The coherently demodulated Walsh correlator outputs are used to form soft decisions (134, 136) that are deinterleaved and soft-decision Viterbi decoded.

Abstract: A foldable portable building (20) can be collapsed to fit within the outside dimensions of an internationally standardised (I.S.O.) goods container to facilitate mechanical handling and transportation. The building (20) comprises a rigid main support having a main floor section (38), a main wall section (58) and a main roof section (56). When the building is extended, generally horizontal and planar, hingedly interconnected floor sections (36, 44) and roof sections (52, 54) extend from the main floor (38) and roof sections (56) respectively, and wall sections (82, 86) extend between the said sections. The wall sections (82, 86) comprise an end wall section (76), two first wall sections (86) and two second wall sections (82) which are hingedly interconnected similarly to a bellows. When the building is collapsed, the wall sections (82, 86) are located adjacent the main wall section (58), the roof sections (52, 54) are disposed vertically on a side of the wall secitons (82, 86) remote from the main wall section (58), and the floor sections (36, 44) are disposed vertically outwardly of the folded wall (82, 86) and roof sections (52, 54). The roof sections (52, 54) form a foldable roof system comprising a base ceiling member (96), trusses (98) and an outer roof member (100). The trusses (98) are parallel to each other and extend generally across and are hinged to the base ceiling member (96). The outer roof members (100) lie on chords of the trusses (98). Minimal vertical space is required for the collapsed roof system which enables a relatively high ceiling to be obtained, and yet still fit within the standardised container sizing.

Abstract: A layered tubing for use in beverage carrying and dispensing composed of a thicker outer layer, a thin intermediate bonding layer and the innermost impermeable and nonreactive barrier layer is disclosed. This invention relates to a new and economically viable method for making a Thermoplastic Multilayer Tubing which is comprised of layer's in which the inner layer P.J.1 is a Barrier layer which does not allow the permeation and diffusion of vapours, gases, moisture; aroma and flavours. The P.J.1 layer which is totally inert, odourless, non-soluble in water, alcohols, beverages, syrups and alike is the beverage contact layer. The P.J.1 is a copolyester with a general formula (C10H8O4)n without any hazardous ingredients and has a melting point range about 160°C and density between 0.9 and 1.0 g/ml. In one construction, the P.J.1 layer is bonded to Ethylene Vinyl Alcohol (EVOH) by a bonding layer P.J.2 which is Polyethylene copolymer with modified polyolefin having approximately % C = 79.2, % H =13.6, %O = 7.6, with trace amounts of N, melting point range 104 - 138°C and specific gravity 0.91 - 0.95 (water = 1). The bonding material is chemically stable under the processing conditions. The outer surface layer is comprised of polyethylene, P.E., with a general formula (C2H4)n having a melting point range of about 180°C. It is bonded to the EVOH  layer by P.J.3 which is modified polyolefin. This is referred to as the Class I tubing of this invention. In another class of tubing, which is referred to as the Class II tubing of this invention, the outer surface layer is comprised of polyethylene, P.E., with general formula (C2H4)n having melting point range about 180°C. It is bonded to the impermeable P.J.1 layer by the P.J.4 layer which is a chemically stable plastic material under processing conditions, having a general formula (C8H16O)n, density of about 0.9, and melting point of about 55°C. The applicants have developed processing conditions for the inner layer P.J.1, and a suitable method for making the beverage tubing and film which meet the attributes of desired tubing and film and solve the long standing problem of vapour and flavour transmission and adsorption in the transfer of flavoured beverages. The film form of P.J.1 can also find its application in the food packaging industry to prevent loss of moisture, flavour and taste. The realization is that P.J.1 is environmentally friendly for beverage holding and dispensing and is envisioned to have numerous potential applications now, and in the new millennium with increasing demand for such tubing. These applications can utilize the unique properties of the P.J.1 layer in an environmentally friendly and cost-effective manner.

Abstract: A sealed collet having improved radial flexibility is provided for facilitating removal from a locknut of a chuck assembly. The sealed collet includes a collet body formed from a tubular configuration of elongated gripping fingers separated by elongated slots which render the body radially resilient in response to pressure applied by a locknut. The slots are filled with a bonding agent, which may be a silicon rubber compound, for preventing dirt and debris from entering the collet slots and for preventing pressurized coolant intended to flow through a bore in a tool shank from flowing through the walls of the collet body. To increase the radial compressibility of the collet, agent-free gaps are provided in the slots immediately behind a distal portion of the collet body.      In the preferred embodiment, the length of the agent-free gap is between 20 % and 30 % of the overall length of its respective slot. The location of the gaps immediately behind the distal end of the collet body advantageously increases the radial compressibility of the collet while allowing the bonding agent in the slots to continue to prevent debris from entering the collet.
