Patent CA-2260285-A1 (CA)
Inventor: ARIMILLI RAVI KUMAR
IPC: G06F12/08
Filed: 1999-01-25
Abstract: A modified MESI cache coherency protocol is implemented within a level two (L2) cache accessible to a processor having bifurcated level one (L1) data and instruction caches. The modified MESI protocol includes two substates of the shared state, which denote the same coherency information as the shared state plus additional information regarding the contents/coherency of the subject cache entry. One substate, S  IC0, indicates that the cache entry is assumed to contain instructions since the contents were retrieved from system memory as a result of an instruction fetch operation. The second substate, S IC1, indicates the same information plus that a snooped flush operation hit the subject cache entry while its coherency was in the first shared substate. Deallocation of a cache entry in the first substate of the shared coherency state within lower level (e.g., L3) caches does not result in the contents of the same cache entry in an L2 cache being invalidated. Once the first substate is entered, the coherency state does not transition to the invalid state unless an operation designed to invalidate instructions is received.  Operations from a local processor which contravene the presumption that the contents comprise instructions may cause the coherency state to transition to an ordinary shared state. Since the contents of a cache entry in the two coherency substates are presumed to be instructions, not data, instructions within an L2 cache are not discarded as a result of snooped flushes, but are retained for possible reloads by a local processor.
Patent CA-2265336-A1 (CA)
Title: Bicycle wheel travel path for selectively applying chainstay lengthening effect and apparatus for providing same
Inventor: CALON JAMIE W
IPC: B62K25/28
Filed: 1999-03-12
Abstract: A rear suspension system for a bicycle. The system directs the rear wheel along a predetermined, S-shaped path as the suspension is compressed. The path is configured to provide a chainstay lengthening effect only at those points where this is needed to counterbalance the pedal inputs of the rider; at those points in the wheel travel path where there is a chainstay lengthening effect, the chain tension which results from the pedal inputs exerts a downward force on the rear wheel, preventing unwanted compression of the suspension. The system employs a dual eccentric crank mechanism mounted adjacent the bottom bracket shell to provide the desired control characteristics.

Title: Rotating disc wood chip refiner
Inventor: LEITH WILLIAM CUMMING
IPC: D21D1/30
Filed: 1999-05-03
Abstract: A rotating disc wood chip refiner apparatus with an improved helical ribbon screw feeder comprising radially positioned right-hand and left-hand helical ribbon bars, each bar having a corresponding feeder outlet ring having a grid of skewed axial slots having a multiplicity of volumes, forming a continuous series of tuned resonant cavities. The slots in a feeder outlet ring corresponding to a right-hand helical ribbon bar are axially and uniformly skewed backwards (i.e. counter-clockwise) for a right-hand screw; and the slots in a feeder outlet ring corresponding to a left-hand helical ribbon bar are axially and uniformly skewed forwards (i.e. clockwise) for a left-hand screw, so that the helical ribbon bar/skewed axial slot-crossings are nearly parallel. A wave packet of forward travelling waves produced by the additional continuous series of tuned resonant cavities at the helical ribbon bar/skewed axial slot-crossings of the improved helical ribbon screw feeder described in this invention, can achieve a Bjerknes resonator action, with synergistic advantages to the usual continuous series of tuned resonant cavities at the refiner plate bar-crossings, at a frequency of half or integral multiples of the frequency of the wave packet of forward travelling waves, which can be adjusted to a family of resonant harmonic vibrations ranging from about 800 hertz to about 30,000 hertz, and provides a longer refining residence time, and achieves increased surface properties for a stronger pulp and paper sheet formation.

Title: Insulating connectors used to retain forms during the manufacture of composite wall structures
Inventor: HANSEN DAVID M
IPC: E04G11/18
Filed: 1999-05-25
Abstract: Connectors used in manufacturing composite wall structures to substantially prevent forms from being displaced in response to pressure generated by concrete poured between the forms. In a completed composite wall structure, the connectors extend through two structural layers and an insulating layer positioned therebetween. The composite wall structures are formed by positioning the insulating layer between and in a spaced-apart relationship to the two forms. The connectors are subsequently inserted through the insulating layer and the forms. As concrete is then poured into spaces between the forms and the insulating layer, a bearing surface on a form retention segment, which extends beyond the outer surface of the forms, abuts the forms and prevents them from moving away from the insulating layer. The bearing surface is either directly positioned on the form retention segment or on a form locking device attached to the form retention segment.  After the concrete hardens, the forms are removed and the form retention segments are optionally detached from the remainder of the connector. The surface of the connectors optionally includes an adhesion promotion material or mechanical anchoring structure to improve the bond between the connectors and the structural layers.

Title: Solid acids as catalysts for the preparation of hydrocarbon resins
Inventor: MORRELL DENNIS G
IPC: C07C2/06
Filed: 1998-01-07
Abstract: Solid acids are used as catalysts for the polymerization of a feed stream containing at least one of pure monomer, C5 monomers, and C9 monomers to produce hydrocarbon resins. Freely-associated water may be removed from the solid acid catalyst prior to use. Resins with softening points (Ring and Ball) in the range of about 5 ~C to 170 ~C can be prepared. These catalysts offer advantages over the traditional Friedel-Crafts polymerisation catalysts since the acid sites are an integral part of the solid. The solid acid catalysts are relatively nonhazardous, reusable catalysts which eliminate or at least reduce contamination of the resulting resin products with acid residues or byproducts.

Abstract: A full-featured data access arrangement (DAA) for connecting a modem to a public switched telephone network (PSTN) includes a bridge current loop circuit, a line in use detection circuit, an off-hook relay, a loop current sense circuit, and an extension/remote event detector circuit. The off-hook relay is connected in series with the current loop circuit to enable the DAA  to detect external off-hook and on-hook events when the modem is in an on-hook state. The DAA is configured to detect the off-hook and subsequent on-hook status of an extension telephone at a location even though the modem and a handset sharing a line connector with the modem are both in an on-hook state.  The DAA is also capable of detecting an off-hook state of an extension telephone even though the modem is in an off-hook state. In addition, the DAA  can detect when a remote telephone device that initiates an incoming call is placed on hook.
