Patent CA-2512180-A1 (CA)
Inventor: SANVILLE KATHERINE
IPC: G05B15/02
Filed: 2004-02-11
Abstract: A method and system for managing chemical usage by service representatives that request dispensing of a chemical product by a chemical dispense system is disclosed. The chemical dispense system prepares and/or dispenses chemical products for service representatives in response to requests by the service representatives. Each service representative that is authorized to use the chemical dispense system is assigned a user identifier (ID). In response receiving a user ID, the chemical dispense system presents on a graphical user interface one or more predetermined chemical products that the service representative is authorized to use. These products are determined based on the user ID. The chemical dispense system prepares and/or dispenses a chemical product in response to the service representative selection of that chemical product. The user ID, the name of the chemical product, and the volume of the chemical product are linked together and associated with a time reference.  This information is sent to a central server for analysis related to the chemical usage trends of the service representative.

Title: Hydrogen manufacture using pressure swing reforming
Inventor: HERSHKOWITZ FRANK
IPC: C01B3/46
Filed: 2004-02-13
Abstract: The invention provides a method for generating high pressure hydrogen at improved thermal efficiencies. First a synthesis gas stream at a first pressure is produced in a pressure swing reformer (128). Next the synthesis gas stream is subjected to a high temperature water gas shift process (130) to produce a hydrogen enriched stream (131) from which high pressure hydrogen is obtained. Specific embodiments of the invention involve: regenerating the reformer at a pressure lower than the synthesis gas generation; operating the synthesis gas generation step at conditions sufficient to provide a syn gas stream at a temperature in the range used in the water gas shift reaction; and using pressure swing adsorption to separate the hydrogen.

Title: Flush valve diaphragm filter
Inventor: HSIAO HAO-YAO
IPC: E03D1/30
Filed: 2005-09-06
Abstract: A flush valve diaphragm filter has a filter body forming a recess section for being assembled to a diaphragm. The filter body defines a main passageway longitudinally therethrough and a plurality of branch passageways transverse therethrough. The branch passageways communicate with the main passageway, and have diameters smaller than the diameter of the main passageway. The flush valve diaphragm filter effectively decreases the ratio of fluid passage being fully clogged, and guides strip-like fibre and lichens to the exterior. Correspondingly, the water filtering function is enhanced.
Patent CA-2520552-A1 (CA)
Inventor: GIBBS BARRIE D
IPC: B27M3/14
Filed: 2005-09-22
Abstract: Protection of wooden articles, such as railroad crossties, against decay or rot is improved through incorporation of borate compounds, such as sodium borate, and a protective coating such as creosote or a resin. Such protection is achieved by placement of a dry borate compound into a hole formed in the wooden article. The hole is then covered, and the borate compound then permitted to migrate and become distributed throughout the wooden article to provide the desired protection. Coating of the thus treated wooden article is conducted either shortly following placement of the borate compound in the hole or at a later convenient time.

Abstract: A wound treatment dressing for applying negative pressure wound therapy to a wound of an extremity, such as on the heel of a foot. The dressing comprises a fluid manifold (14) positioned within a fenestrated drape (16) to form a contoured occlusive wrapping (10) for placement over a wound on an extremity.  A contoured porous pad (26) is placed adjacent or within the wound, such that the contoured pad (26) is enveloped by the occlusive wrapping (10). Flexible tubing (42) is attached to or through a fluid communication port (18), which forms an opening to the outer layer (16b) of the occlusive wrapping (10), so as to allow for fluid communication of negative pressure to the contoured pad (26) from a source of negative pressure (44) connected to an opposite end of the flexible tubing (42). The negative gauge pressure is communicated from the source (44), through the tube (42), through the fenestrations (19) of the occlusive wrapping (10), such that negative gauge pressure is applied to the wound on the extremity. The fluid manifold (14) serves to direct the negative pressure from a position away from the wound site to the contoured pad (26) at the wound site.

The inventive method consists in: stirring an organic sludge having a dryness of between 12 and 18 % with steel balls having a temperature of between 145 DEG C and 165 DEG C, such as to produce a mixture of dry combustible particles and balls; and subjecting the mixture thus produced to a hot air stream having a temperature of between 350 DEG C and 395 DEG C, thereby causing the thermal oxidation of the dry particles. The method and device can be used to produce very compact units in order to satisfy sludge disposal requirements. The invention is particularly suitable for the in situ thermal oxidation of organic sludge produced by small and medium treatment plants.
Patent CA-2548085-A1 (CA)
Inventor: SHALEV LEAH
IPC: H04L1/22
Filed: 2004-12-08
Abstract: A network interface controller implementation that performs direct data placement to memory where all segments of a particular connection are aligned, i.e. cuts-through without accessing reassembly buffers (i.e., a "Fast"  connection type), or if all segments are non~aligned moves data through reassembly buffers (i.e., a "Slow" connection type). The type of connection can change from Fast to Slow and back. The implementation preferably conducts CRC validation for a majority of inbound DDP segments in the Fast connection before sending a TCP acknowledgement confirming segment reception. The method of computing a CRC value according to the present invention assumes that each TCP segment starts with an aligned DDP segment and that the first two bytes of a TCP payload is an MPA length field of an MPA frame.
