Patent CA-2177087-C (CA)
Inventor: NETUPSKY BORIS
IPC: E01D15/14
Filed: 1996-05-22
Granted: 2000-04-25
Abstract: This invention comprises the use of the force of buoyancy to counter the gravity forces due to the dead and live loads imposed on bridge structures spanning bodies of water.   This is achieved by securing to the underside of the bottom chord or element of the bridge superstructure, restrained at each end from vertical movement, a buoyancy block or a plurality of buoyancy blocks submerged at all levels of the body of water, thus providing the desired prestress to the superstructure to counter the gravity loads. Further, in a trussed type of superstructure, buoyancy collars may be secured to the vertical elements of the truss, providing additional prestressing forces when the body of water rises and a resistance to the deflection of the bridge structure from the live loads, thus reducing the shearing forces, bending moments, and reactions at the two ends or abutments of the bridge.

Patent CA-2185745-C (CA)
Inventor: CHEN JUIN-HWEY
IPC: G10L19/02

Granted: 2001-02-13
Abstract: A speech compression system called "Transform Predictive Coding", or TPC, provides for encoding 7 kHz wideband speech (16 kHz sampling) at a target bit-rate range of 16 to 32 kb/s (1 to 2 bits/sample). The system uses short-term and long-term prediction to remove the redundancy in speech. A prediction residual is transformed and coded in the frequency domain to take advantage of knowledge in human auditory perception. The TPC coder uses only open-loop quantization and therefore has a fairly low complexity. The speech quality of TPC is essentially transparent at 32 kb/s, very good at 24 kb/s, and acceptable at 16 kb/s.

Abstract: A cylindrical perforated member is mounted between a working fluid inlet port 6 and a hermetic vessel 1a that a working fluid supplied into the hermetic vessel at the working fluid inlet port will not directly contact the forced-feed liquid surface. At the working fluid inlet port is mounted a ring-shaped member with a divergent section having the smallest flow passage area.  The working fluid stream is deflected and dispersed by the cylindrical perforated member, to produce a pressure for feeding the liquid rapidly within the hermetic vessel, thus enabling the rapid forced-feed of the liquid.

Title: Server-to-cache protocol for improved web performance
Inventor: SIBAL SANDEEP
IPC: G06F17/30
Filed: 1997-09-24
Granted: 2002-01-22
Abstract: On the Internet (106), rather than retrieving a frequently requested Web object from its originating server (105) in response to a request from a client terminal (101, 102), the object rather can be retrieved from a cache (103) within the Internet Access Service Provider (IASP) (104), which connects the client terminal to the Internet. What is stored in the cache may, however, not be the most recent version of the object. Distinct from providing the Web object itself, information about changes to the object is provided by the server in response to a cache request that is asynchronous to a request from a client for the object. Such information about changes to an object includes the date and time when the object was last modified, the byte size of the modified object, and information on the type of content of the object. After receiving this information about changes to an object, the cache may then request that a copy of the object be downloaded to it.

Abstract: Disclosed is a water distiller of the type having a raw water container, a heater for boiling water in the container and a thermostat for disabling the heater.  In the improvement, the container includes a water cavity having a upper perimeter around a panel and the heater is mounted in heat-transfer relationship to the panel.  The container includes a thermostat in heat-transfer relationship to the panel and connected to the heater. When water diminishes to a level at which the panel is no longer submerged, the panel temperature rises and trips the thermostat.             A heater retention member secures the heater to the panel and a reflective heat shield has a first portion spaced from the retention member.  The heater is between the panel and the first portion.  The thermostat projects through an aperture in the retention member and an opening in the heat shield so that such thermostat is in intimate, heat-transfer relationship to the panel.

Abstract: Un récepteur reçoit un signal ATV (par exemple, HDTV) dans une zone soumise à un brouillage dans la même voie NTSC et à d'autres interférences. Le signal reçu est codé préalablement au niveau de l'émetteur afin de pouvoir limiter le brouillage dans la même voie NTSC dans le signal reçu. Le signal reçu comprend des signaux de synchronisation de trame soumis successivement à un filtre à peigne, de manière à produire un signal de soustraction. Ce signal de soustraction est soumis à un filtre à peigne afin de limiter le brouillage dans la même voie NTSC et appliqué à un comparateur (36) avec le signal de soustraction non filtré. Le comparateur détermine si le niveau de brouillage dans la même voie NTSC est suffisamment important pour soumettre le signal ATV reçu à un filtre à peigne, afin de limiter ledit brouillage.

Granted: 2002-12-10
Abstract: In a method of transmitting an IP packet between a source and a destination through an ATM network which has a node formed by an ATM switch and a packet router, a reception packet or cell is transmitted to the node on an unused or undefined VC and is sent to the packet router in the node. In the packet router, an output port is selected by the use of the unused VC to establish a switched virtual channel in the ATM switch and to transfer each packet through the switched virtual channel after the switched virtual channel is established, as long as the reception packet is sent on the same VCI.  Neither signaling nor protocol is needed between the nodes.

Inventor: MANGNUS PETRUS JOSEPHUS
IPC: C07C9/16
Filed: 1996-11-28
Granted: 2006-07-25
Abstract: The invention pertains to a process for preparing an activated catalyst composition in which a catalyst composition comprising a Group VIII noble metal and a hydrocarbon-substituted aluminium compound on an alumina carrier containing up to 20 wt.% of other components is activated by being contacted with a hydrogen-containing gas at a temperature in excess of 500 .degree.C, with the proviso that at least when he hydrocarbon-substituted aluminium compound present in the catalyst composition is not a hydrocarbon-substituted aluminium halide, he catalyst composition to be activated is contacted with a halogen compound either prior to or during the activating step. The catalyst obtainable by this process and the use thereof in hydrocarbon conversion processes, such as isomerisation and alkylation processes, are also part of the present invention. The effect of the high-temperature activation step is that the activity of the thus obtained catalyst is improved in comparison with a catalyst of the same composition which has not been subjected to said high temperature activation step.

Abstract: The present invention relates to a method for making improved paper structures that can be produced economically and which provide increased strength without sacrificing softness and absorbency.      Conventional papermaking methods teach dewatering of a paper web by pressing the web between two felts that ideally should have a relatively high density and low pore size and permeability. The present invention provides a method of forming a paper web with improved dewatering wherein the web is pressed with an imprinting member between two felt layers. The present invention provides a method that facilitates the dewatering process. This is accomplished by the use of two felts have different air permeabilities and by removing the felt from the web at the nip exit.
