Patent CA-2434229-A1 (CA)
Inventor: ZULAWSKI DENNIS
IPC: F16H55/56
Filed: 2003-07-03
Abstract: The invention relates to a belt-driven clutch system having a driven clutch with a particular arrangement of cam followers and cam slots. One embodiment of the invention is a clutch having a fixed sheave, a movable sheave and a housing mounted to the movable sheave. The housing has a cam slot with first and second cam surfaces. The clutch also includes a pair of cam followers that is secured to the fixed sheave for acting upon the cam surfaces of the cam slat.  A first cam follower of the pair of cam followers acts upon a first cam surface of the cam slot and a second cam follower of the pair of cam followers acts upon the second cam surface of the cam slot to reduce backlash and provide more responsive operation. The invention also provides adjustment of spring tension and belt width without requiring removal or disassembly of the clutch.

Title: Compression system for low-bandwith client-server data link
Inventor: JORDAN JAMES
IPC: H04N21/2343
Filed: 2002-02-01
Abstract: In a method of transferring data from a server to a remote client over a communications link, a request for specific data is sent from the remote client to the server accompanied by a compression request for transmission of the data at a specified compression ratio. Upon receipt of this request, the server retrieves the specific data from a data source, such as a web server or ftp server. An agent at the remote server intercept the retrieved data and compresses at least part of the retrieved data prior to transmission. After transmission to the remote client in compressed form over the communications link in accordance with the compression request, the data is decompressed and restored to an uncompressed intelligible form.

Abstract: La présente invention concerne un procédé permettant de produire de la mélamine de grande pureté avec des rendements élevés, par pyrolyse d'urée à une température comprise entre 360 et 420 ·C et à une pression supérieure à 7 MPa, les produits de réaction, qui comprennent une phase gazeuse et une phase liquide, étant soumis à des traitements successifs pour permettre la purification et la récupération de la mélamine. Ce procédé se caractérise en ce que la phase liquide provenant du réacteur de pyrolyse contenant la mélamine, l'urée non soumise à réaction, les produits oxydés intermédiaires de la pyrolyse et les produits de la condensation par extraction d'ammoniac de la mélamine (polymères de condensation), est envoyée vers un réacteur aval (post-réacteur) fonctionnant dans des conditions de température et de pression sensiblement identiques à celle du réacteur de pyrolyse; en ce que les phases gazeuses anhydres provenant du réacteur de pyrolyse et du post-réacteur sont soumises au lavage au moyen d'urée fondue pour récupérer la mélamine contenue dans lesdites phases gazeuses sous la forme de vapeur, avant d'être renvoyées vers l'unité de synthèse de l'urée pour permettre la récupération du NH¿3? et du CO¿2? contenus; en ce que le liquide purifié provenant du post-réacteur est traité dans une colonne de refroidissement à une température comprise entre 160 et 170 ·C en présence de 10 % en poids minimum de NH¿3? afin d'éliminer les polymères de condensation; en ce que la sortie de la colonne de refroidissement est refroidie et qu'une mélamine de grande pureté est séparée par cristallisation d'une liqueur mère qui est directement recyclée à hauteur de 80 % minimum vers la colonne de refroidissement, ce qui permet la récupération à bas prix de l'ammoniac et de la mélamine. La liqueur mère qui n'est pas directement recyclée est traitée pour permettre la séparation des produits oxydés intermédiaires de la pyrolyse, puis elle est renvoyée vers la colonne de refroidissement de manière à permettre la récupération complète de la mélamine produite dans le système de réaction.

Abstract: This patent applies to a wheel motor which generates a propulsive force through the use of a chambered or segmented tire. Consider a standard automotive rubber tubeless tire with, say 12, independently inflatable rubber bladders arranged in place of a normal tube.  Then by increasing the pressure in one of the chambers in contact with the ground but not centred on flue ground contact patch, the wheel will rotate as it "falls" off of this higher pressure chamber. By continuous adjustment of chamber pressures continuous rotation can be obtained. Similarly these chambers or segments could be filled with other fluids or expansible solids.

Abstract: It has now been found that the incorporation of nanosized metal particles into cyclodextrin-containing material leads to a "reactive" barrier material having excellent barrier properties. More specifically, it has been found that the presence of nanosized metal or metal alloy particles in a barrier material, preferably a thermoplastic material, wherein said material comprises cyclodextrin derivatives, is advantageous in achieving excellent barrier properties. The barrier material of the present invention provides improved barrier resistance to a variety of permeants and/or impurities. The diffusion of volatile substances through the barrier material is prevented by adding compatible derivatized cyclodextrin and nanosized metal particles to the material used. Accordingly, the inventive material also is suitable for many applications including food-contact packaging, flexible packaging to dispose of adult and baby diapers, incontinent products, hospital and household waste and also for packaging pharmaceutical products, medical devices and dental materials.

Title: Improved structure foldable assembly-type lamp shade
Inventor: WU WEN-CHANG
IPC: F21V1/06
Filed: 2001-04-09
Abstract: An improved structure foldable assembly-type lamp shade comprised of a top ring at the uppermost end of the lamp shade, a bottom ring of larger circumference than the top ring, and frame members propped between the top ring and the bottom ring. The bottom ring has fixing mounts consecutively disposed at the frame member locations that provide for the assembly and positioning of the frame members, with the fixing mounts at the support member installation locations having different type connection sections based on the respective type of fixing mount arrangement utilized. When packaged, since the frame members can be first folded down and whorled into a flat state such that the frame members and the top ring are stacked on the bottom ring, the lamp shade of the present invention occupies the smallest physical assembly area to facilitate ease of assembly and, furthermore, the resulting minimized storage area effectively reduces shipping costs.

Abstract: At least one queue is provided per current branch pattern in a network node. In this way, a queue can be jointly used for a plurality of distribution compartments which are imaged onto the same branch pattern in said node. Arriving packets are differentiated according to the particular distribution compartment to which they belong (i.e. not according to a particular flow to which they belong inside the distribution compartment). They are then insert ed into a corresponding queue accordingly. Said queues are used by the ports belonging to each branch pattern. As soon as a port is free, it selects the next queue to use. The selection thus begins in sufficient time to ensure th at no gaps appear on the outgoing line from said port. If a port uses a plurali ty (in this case fully or partially overlapping) of branch patterns, a search i s then carried out for non-empty queues in all of said branch patterns, during the selection. If a plurality of non-empty queues are found in different branch patterns, the following queue to be used is selected according to a p re- determined criteria. The packet to be emitted from said queue is then define d according to a further criterion.
