Patent CA-2257388-A1 (CA)
Inventor: ARNAUTS JAN EUGEEN FREDERIC
IPC: C08G69/36
Filed: 1997-06-06
Abstract: The invention relates to a polyamide fibre whose polyamide is heavily branched. The branched polyamide preferably has 3-20 branches which are joined to a core molecule which is smaller than the polyamide arms. The arms originate preferably from functional groups which are identical and are preferably carboxyl groups. The polyamide is chosen from the group of polyamides which are produced by polycondensation of .alpha.,.omega.-aminocarboxylic acids or by ring-opening polymerization of lactams.  Preferably, the polyamide is nylon-6. The properties of the fibre according to the invention are at least at the same level as those of fibres obtained by spinning linear polyamide. The spinning process for the fibre according to the invention is less susceptible to faults. Inter alia, the viscosity of the polyamide no longer changes during the spinning process.

Title: Clothes hamper
Inventor: SMILLIE ALEXANDRA M
IPC: D06F95/00
Filed: 1999-02-16
Abstract: A container for sorting and storing items to be laundered is described. The container comprises two lower compartments for storing bulkier items and two inner compartments arranged to pivot within the container from a position wherein the inner compartment(s) are within the container to an outward position wherein the inner compartment(s) are outward of the container. Furthermore, the inner compartments are arranged to accept one or more rigid inserts therein. In operation, items to be laundered together are deposited into the desired rigid insert(s). When laundry day arrives, the rigid insert(s) are removed from the inner compartment(s) of the container and emptied directly into the washing machine. As the items to be laundered have already been sorted, the time and effort required to do the laundry is significantly decreased. Finally, the container, the inner compartments and the rigid inserts all include air holes for improving air circulation throughout the container so that odors and smells do not accumulate.

IPC: H04N21/43
Filed: 1997-11-13
Abstract: A digital television signal includes successive frames of two fields each comprising 313 data segments with the first data segment in each field functioning as a field sync. The field sync segment comprises a 511 pseudo-random number (PN) sequence and three 63 PN sequences, with the middle one of the 63 PN sequences alternating polarity in successive fields. A reference data segment is compared with the 511 PN sequence in each data segment and the data segment with the least number of errors is identified as the first data segment in the field. The corresponding portion of the reference segment is compared with the middle 63 PN sequences in the identified first data segments and that with the least number of errors is determined to be the first segment in the frame. Confidence counters are used to assure reliable determinations.

IPC: G06F3/041
Filed: 1999-05-26
Abstract: A touch pad for controlling electronic equipment includes a deformable touch surface and a compressible pad body in contact with the touch surface. The compressible body is formed from a material which scatters or diffuses light within the material.  Multiple sources of light or other wave energy are directed into the interior of the substrate to form multiple illuminated cells inside the pad body. Each illuminated cell forms an integrated cavity within the pad body. A detector in communication with the compressible material detects light intensity within the integrated cavity. A  processor receives signals from the detector and converts the signals into useable information relating to the position of regions of compression of the pad.

Title: Top coupling arrangement for a reciprocating pump
Inventor: CONN KENNETH S
IPC: F04B47/02
Filed: 1999-10-01
Abstract: An improved coupling arrangement is provided for coupling connected to the top of a plunger which reciprocates in a pump barrel. The coupling provides fluid ports for discharging fluid from the bore of the plunger and coupling to the annulus between the coupling and pump barrel. The lower edge of the ports is positioned below the leading edge of plunger, or conversely the leading edge of the plunger is re-formed above the lower edge; of the coupling's ports. Accordingly, solids cannot be trapped between the leading edge of the plunger and barrel and pump live is markedly improved. Preferably the plunger's leading edge is formed by the novel coupling so that industry standard plunger's can be used. Further, the plunger's leading edge is preferably fitted with a wiper which is even more preferably backed by a stack of seals fitted into a pressure-equalized annulus located below the wiper.

Abstract: L'invention reconnaît les effets nocifs de quantités à l'état de traces et même de quantités non détectables de cations multivalents sur la séparation de mélanges de polynucléotides et plus particulièrement de polynucléotides à double brin, et elle a trait à un procédé amélioré permettant de séparer ces mélanges sur des milieux de séparation non polaires à pores de grandes dimensions au moyen de l'élimination de cations multivalents. Pour cela, on utilise dans le procédé de séparation des constituants qui sont des matières ne libérant pas de cations métal. On décrit également l'utilisation de résines de captage de cations et l'utilisation d'autres procédés pour éliminer les traces résiduelles de cations multivalents dans des solvants d'élution, des solutions d'échantillon, des milieux de séparation et des constituants du système. Il est également important d'éliminer toutes les traces ou tous les contaminants organiques éventuels dans des solutions de solvants et des parties du système. L'utilisation d'étapes similaires pour éliminer dans le processus de séparation les traces résiduelles de cations multivalents et d'impuretés organiques permet à cette invention d'être également utilisée dans un procédé de traitement en lot servant à séparer des mélanges de fragments de polynucléotides.

Abstract: A roll assembly (20) for high temperature applications comprising a roll body (22) and trunnions (30) on opposing ends (24) thereof is disclosed. The roll body and supporting trunnions are comprised of alloys having dissimilar coefficients of linear thermal expansion. The trunnions are attached to the roll body so that there is a predetermined gap (40) at room temperature that decreases or closes at a desired operating temperature. The gap decreases due to the dissimilar thermal expansions between the roll body and the trunnions.  In certain embodiments, the distance of the gap is determined so there is a tight predetermined interference fit between the trunnions and the roll body for roll assembly integrity and load transfer. In other embodiments, the distance of the gap is determined so that a plurality of mechanical connectors (44) extending between the roll body and the trunnions provide the roll assembly with integrity and provide load transfer between the roll body and the trunnions.

Title: Internal combustion engine exhaust treating apparatus and method (diesel)
Inventor: SCAPPATURA DOMINIC E
IPC: B01D53/92
Filed: 2000-03-07
Abstract: An apparatus and method for the removal of carbon particles (soot), odor, gas and particulate from the exhaust of a diesel engine. The method includes a carbon (soot) collector which collects the carbon (soot) and noxious odor which is connected to the catalytic converter of the engine, then enters a heat exchanger for cooling and condensing a major portion of the exhaust into a liquid condensate. The condensate enters a first reactor which neutralizes any acids present in the condensate and passes through an automatic drain into a holding tank. The non-condensed gases flow into a second reactor connected to a holding tank. Gases are reacted in the second chemical reactor with a substance which absorbs the carbon monoxide and nitrogen oxide.  The two reactors remove a large quantity of nitrogen oxides and particulate matter. The treated gases then flow into a soot bath for removal of minute carbon (soot) particles and thence into a vapor remover. The treated gases then are let out into the atmosphere through an exhaust outlet.
