Patent CA-2153170-A1 (CA)
Inventor: WYNN WOODSON DALE
IPC: G10L21/0208
Filed: 1994-11-15
Abstract: A telecommunications network service (figure 1) overcomes the annoying effects of transmitted noise by a signal processing which filters out the noise using interactive estimations of a linear predictive coding speech model. The speech model filter uses an accurate updated estimate of the current noise power spectral density, based upon incoming signal frame samples which are determined by a voice activity detector (25) to be noise-only frames. A novel method of calculating the incoming signal using the linear predictive coding model provides for making intraframe iterations of the present frame based upon a selected number of recent past frames and up to two future frames (figure 3 and figure 10). The processing is effective notwithstanding that the noise signal is not ascertainable from its source.

Patent CA-2160690-A1 (CA)
Inventor: LINZELL GEOFFREY ROBERT
IPC: B23K35/36
Filed: 1994-04-25
Abstract: In the Specification of our International Patent Application PCT/GB 91/00950 there is described and claimed a method of securing against lateral motion two bodies held in face to face asperity contact, thereby to make a join between the two bodies, in which methods there is inserted into the interface between the two bodies a material that on minimal initial lateral relative motion of the two surfaces promotes rapid but controllable "galling" between the two surfaces, this galling binding the surfaces against further such motion. However, this method requires the two surfaces to fit well one to the other, and without such a good fit the resultant join may not be entirely satisfactory. The present invention's proposed solution to this gap problem is to use a metal-particle-containing composition comprising the gall enhancing agent loaded with a myriad of small metal particles, which composition can be packed into the gap, and will flow to accommodate a wide range of gap sizes and also to accommodate out-of-round distortion. The composition can take various physical forms, typically those of a free-flowing powder, a viscous liquid, or a stiff paste (and the powders have an additional use in the preparation of preforms for the manufacture of sintered parts).

Title: Drying section with additional press nip
Inventor: BUBIK ALFRED
IPC: D21F5/04
Filed: 1996-03-01
Abstract: A drying section of a paper machine includes a plurality of individual drying groups, wherein the drying cylinders of a drying group are served by A respective dryer wire or felt that passes over drying cylinders of the drying group and presses a web to be dried against the surface of the drying cylinders.  The invention is adapted for either single tier or double tier drying groups.  At least one press roll is disposed between and separates two of the drying groups.  In one embodiment, the at least one press roll forms a nip with the adjacent drying cylinder, either upstream or downstream, to define a dewatering nip through which the web passes.  A dewatering belt passes over the press roll in the nip. The wire for a respective drying group is guided away from the dewatering nip so that only the web and the dewatering belt pass through the press hip.  In alternate embodiments, two press rolls may be disposed between the adjacent drying groups, and the two press rolls define a press nip between them.  A respective dewatering belt passes over each of the press rolls.  One of those press rolls may also be in contact with and define a press nip with the adjacent drying cylinder in the adjacent drying group.  An open draw free path may be defined between one of the press rolls and the adjacent drying cylinder.

IPC: H04N7/173
Filed: 1996-03-21
Abstract: A system and method for the segmentation of data exhibiting an intrinsic long-term average data rate, punctuated with periods of peak rate data bursts. This segmentation conditions the data for efficient transmission via either a renegotiated constant bit-rate ("RCBR") network or a renegotiated variable bit-rate network ("RVBR") network. Within these networks, data transmission rates between a sender and a recipient are rapidly renegotiated as a function of previously stored data transmission demand information and system buffer levels. Such a system that is responsive to the rate at which new calls or requests for connections enter and leave the network, the frequency and duration of extended peak rate data bursts, as well as the occurrence of short duration data transmission peaks.

Title: Keyless Latch for Orienting and Anchoring Downhole Tools
Inventor: COMEAU LAURIER E
IPC: E21B23/02
Filed: 1996-06-27
Abstract: A joint of tubular casing with a pre-formed window in its sidewall, has a tubular sleeve fixedly attached to the interior of the tubular casing by a plurality of shearable set screws. The exterior surface of the sleeve is sealed to the interior surface of the tubular casing on opposing sides of the window. The window is filled with a fluid and then the window is covered with one or more layers of a composite material such as fiberglass. In use, the joint of tubular casing is run down to the depth of interest in an earth borehole, and then the window is oriented with respect to the formation of interest at the depth. The joint of tubular casing is then cemented in place, after which the tubular sleeve is retrieved by the use of a fishing tool causing the set screws to shear upon the upward movement of the fishing tool.  After the interior sleeve is retrieved, a whipstock is lowered into the cased borehole, until it is oriented and anchored therein. The assembly automatically fixes the axial and circumferential orientation of the whipstock within a surrounding casing joint and holds the assembly in place. Alignment and fixing of the whipstock ensures proper engagement and orientation of a drill bit with an access window formed in the casing wall. The assembly employs multiple spring loaded latches which register with and extend into corresponding receiving recesses formed on the inner surface of the casing joint. The recesses, which are spaced circumferentially around the interior of the casing joint, contain differing profiles which uniquely mate with corresponding profiles on the latches. The relative position of the latches with the recesses determines the amount of radial latch movement providing keyless anchoring and orientation of the assembly within the casing. Setting is positively confirmed with a simple rotational force on the setting string. The spring loaded latches release from anchored, oriented position in response to an upward axial force exerted by the drill string to provide a straight pull release of the assembly. Confirmation of correct axial location and proper circumferential orientation may be made by surface monitoring of the setting string weight and turning torque.

Patent CA-2181641-A1 (CA)
Inventor: WILHELM DONALD M
IPC: F28C3/14
Filed: 1996-07-19
Abstract: A counter flow cooler in which feed material is fed into the top inlet of the cooler and dispersed into a plurality of cooling chambers.  At the bottom of each cooling chamber is a discharge grid which will discharge feed material uniformly over the area of the cooling chamber.   The discharge rate of this discharge grid can be adjusted to the desired throughput of the cooler.    Air is drawn through the bottom of the discharge grid and passes up through the feed material in a counter flow manner.  That is, while the product is passing down through the cooler, the air is passing up through the feed material,  carrying away heat and possibly.  A feed controller is used to selectively direct feed material into the plurality of cooling chambers.  When a second batch of feed material is to be introduced into the cooler, feed material to the first cooling chamber is stopped and all the feed material is directed into the second cooling chamber.  When the first cooling chamber is empty, its discharge is closed and the new feed material is directed into the first cooling chamber and feed material to the second cooling chamber is stopped.  When the second cooling chamber is empty,  the new feed material can be directed into the second cooling chamber and discharge of the new feed material from the first cooling chamber can begin.
