Patent CA-2251458-C (CA)

Abstract: An inserted lid (1) for a box (2) is formed so that a contact region (5) can be pressed against the inside of the side wall of the box. In the non-inserted state, said side wall is slightly larger than the box opening (4). on insertion of the lid (1) into the box (2), the largest circumferential line of the contact region (5) must fit the inside of the side wall of the box as a result of an elastic deformation of the closure surface (3). To prevent the forces emanating on insertion from the side wall of the box from leading to irreversible deformations, the closure surface (3) has spring properties which are radial with respect to the contact region (5) and permit an elastic deformation of the contact region (5) in the radial direction. To ensure these spring properties, the closure surface (3) has a shape differing from a flat surface, in particular two concentric waves (7) formed constant distances away from the contact region (5) and/or a central vault (8). On insertion of the lid (1), this difference is slightly increased by the compression of the contact region (5), or the waves (7) and the vault (8) are slightly deformed, which leads to storing forces which press the contact region (5) against the inside of the side wall of the box. Owing to the shape imposed on the closure surface (3) , it is ensured that no creases or other irreversible deformations form on insertion of the lid (1) .

Abstract: An assembly technique and device for enclosing an open end of a movable socket (10) comprised of fully hardened materials with an expanding cover-plate (66) and for positioning the cover-plate at a predetermined distance from an exposed pressure plate (62) of the movable socket so as to provide a reliable indicator of socket wear. During assembly, various internal components of the movable socket, including the pressure plate, are installed within a housing (12) through a posterior opening (16) with the cover-plate is positioned over the components. A two-stage ram (100) having first and second contact surfaces (142, 167) is brought into engagement with the cover-plate. Pressure exerted by the two-stage ram is transferred to the cover-plate through the first surface, expanding the cover-plate into a generally planar configuration and enclosing the internal components within the socket housing.  A continued increase in pressure extends the second contact surface into engagement with the cover-plate, further deforming the cover-plate to a predetermined final position relative to an internal component for a consistent indication of wear on the socket components within the housing.

Title: Transmitting system for small-sized vehicle
Inventor: MAKITA SEIJI
IPC: B62M7/02
Filed: 1999-11-12
Granted: 2003-09-16
Abstract: In a transmitting system for a small-sized vehicle in which a crankshaft of an engine and an input shaft of a multi-stage transmission are connected to each other through a fluid transmitting device, the fluid transmitting device and a shifting clutch are mounted on the crankshaft. One of the fluid transmitting device and the shifting clutch is connected to the crankshaft, while the other is connected the input shaft of the multi-stage transmission through a primary reducing device. Provided in the crankshaft are an upstream supply oil passage connected to an oil pump, a downstream supply oil passage connected to portions to be lubricated of the engine, a flow-in bore which permits the upstream supply oil passage to communicate with the inside of the fluid transmitting device, and a flow-out bore which permits the inside of the fluid transmitting device to communicate with the downstream supply oil passage. Thus, when the multi-stage transmission is to be shifted, a shifting operation can be conducted lightly, irrespective of a creep phenomenon of the fluid transmitting device by bringing the shifting clutch into its OFF state.      Moreover, lubricating oil for the engine can be utilized to operate the fluid transmitting device and hence, an exclusive oil pump for the fluid transmitting device is not required.

Title: Preparation of functionalised polyethers
Inventor: MCDANIEL KENNETH G
IPC: C08F290/06
Filed: 1998-08-24
Granted: 2009-11-24
Abstract: Unique, well defined polyethers containing both hydroxyl-functionality and unsaturation-functionality are prepared by oxyalkylating an unsaturated monomer having at least one oxyalkylatable hydrogen in the presence of an effective amount of a double metal cyanide complex catalyst, optionally, when necessary, in the presence of a free radical polymerization inhibitor. The resulting polyethers are eminently suitable for such uses as polymer polyol stabilizers or stabilizer precursors, and both in situ and ex situ impact modifiers for thermoplastics. Unique, well defined macromonomers containing hydroxyl-functionality, unsaturation-functionality, and polyoxyalkylene segments are prepared by oxyalkylating an unsaturated initiator molecule having at least one oxyalkylatable hydrogen in the presence of an effective amount of a double metal cyanide complex catalyst, optionally, when necessary, in the presence of a free radical polymerization inhibitor. The resulting unsaturated macromonomers are eminently suitable for such uses as copolymerization with ethylenically unsaturated monomers containing carboxylic acid-based groups such as acrylic acid to form effective superplasticizers and water reducers for cement and concrete applications.

Abstract: L'invention concerne un appareil d'imagerie d'un forage comprenant un outil disposant d'une série de boutons d'électrode de tension (32a, b,à) montés sur un tapis non conducteur (30). Une source d'électricité (34, 38) et un retour de courant (36, 40) sont placés, de préférence, sur les tapis non conducteurs au niveau de leurs extrémités opposées. Les emplacements de la source de courant (34, 38) et du retour de courant (36, 40) servent à faire circuler un courant dans la formation parallèle à la face du tapis et non parallèle aux couches limites de la formation. Selon un procédé, la différence de tension entre une paire de boutons de la série est proportionnelle à la résistivité du lit de la formation adjacente aux boutons. Le rapport des différences de tension entre deux paires proches de boutons d'électrode assure une mesure quantitative du rapport de la résistivité creuse. La résolution de l'image produite par ce nouvel outil est déterminée uniquement par l'espacement des boutons.

Granted: 2008-06-17
Abstract: A demand television system (100) comprising a broadcast encoder (250) and a storage encoder (252). The broadcast encoder encodes a real-time video frame sequence to form a broadcast bitstream and broadcasts the broadcast bitstream to a plurality of subscriber equipment (106), while simultaneously the storage encoder encodes the real-time video frame sequence to form a storage bitstream that is stored in an information server (108). The subscriber equipment decodes (510) the broadcast bitstream to display the broadcast program. At any time, the subscriber equipment may request (524) to review the information previously displayed in the broadcast bitstream. As such, the storage bitstream is transmitted (526) to the subscriber equipment.

Abstract: A computer-implemented process rates pipe segments in a water distribution system, the water distribution system including pipe segments and hydrants. Information gathered from maintenance tasks and inspections performed on the pipe segments and hydrants within the water distribution system is stored in an electronic database. The information in the electronic database is analyzed for a specified period of time to determine the presence of water quality factors and service interruption factors. Points are assigned to the pipe segments based on the presence of the water quality factors and service interruption factors. The pipe segments are rated based on the total points assigned to the pipe segments. The pipe segment ratings can be used for prioritizing the replacement of pipe segments in the water distribution system.
