Patent CA-2249287-A1 (CA)
Title: Photoactivatable chain transfer agents
Inventor: AMOS RICHARD A
IPC: C08F2/38
Filed: 1997-03-20
Abstract: A photoactivatable reagent useful as a chain transfer reagent for providing a semitelechelic polymer having one or more terminal photoactivatable groups. The reagent provides one or more photoactivatable groups and one or more sulfhydryl (or other chain transfer) groups, the photoactivatable and chain transfer groups optionally being joined together by a spacer group. The reagent can be used to prepare a polymer by serving to initiate the polymerization of ethylenically unsaturated monomers. The reagent itself becomes an integral part of the resultant polymer, thereby providing the polymer with a terminal photoactivatable nature. The method provides a number of benefits, including the ability to provide homogeneous photoactivatable polymer compositions, e.g., in terms of the uniform location of the photogroup(s) on the terminal portion of each polymer molecule and the ability to build a desired nonpolar quality, and in turn improved surfactancy, into otherwise polar polymers.

Title: Network management framework
Inventor: RIGORI SERGE ANDRE
IPC: H04L12/24
Filed: 1998-10-02
Abstract: A generic management framework for a network management system enables management services and management agents to be added in use as required. Management services can be loaded or plugged into the framework dynamically. As a result a management structure can be provided which is scalable and dynamic and can evolve as requirements change. Management information is modelled as management beans. Network management adaptors can also be added as required to the framework to support protocols such as HTTP, SSL, RMI, SNMP. Remote applications can thereby control the management beans remotely through different protocols.

Title: Metalized paperboard
Inventor: KUZNETSOV VLADIMIR G
IPC: C23C14/02
Filed: 1999-04-20
Abstract: A harmonic mitigating device connected between the power distribution system and the load provides a flux shifting multiple-winding reactor with a capacitor bank connected between the reactor windings. At least one line winding is oriented in a first polarity on a core, and at least one compensating winding oriented in the opposite polarity on the core and connected between the output of the first winding and the load. The opposing fluxes generated by the line winding and the compensating winding cancel and thus reduce the through-reactance of the device between the load and the power supply. The input of a cross-link circuit comprising a capacitor is connected between the line winding and the compensating winding. The reactance through the cross-link circuit to the neutral (or another phase) is lower than the reactance through the line winding. Harmonic currents thus flow through the cross-link circuit, and are largely prevented from penetrating the power distribution system.

Title: Support of resilient material under a compression attached to a rail anchorage
Inventor: MOLYNEUX GODFREY MATTHEW OWEN
IPC: E01B9/62
Filed: 1999-09-15
Abstract: This invention relates to rail anchorages that are used with all rails, but is particularly concerned with adjustable rail anchorages, which allow rail alignment to be adjusted, and which are installed on rails used by cranes. To reduce this rail movement and to help limit vertical uplift of the rail, pressure is applied to the rail flange by resilient material attached to the part of the rail anchorage that overhangs the rail flange. The object of this invention is to provide support to the resilient material in a way that its length can be increased from the bonded surface or outside of the pocket in which it is installed. The invention allows for a greater variation in rail size and rail elevation that can be accommodated with one rail anchorage type and differing lengths of the resilient material.

Inventor: ESTLANDER PETER
IPC: A47F1/03
Filed: 1998-02-18
Abstract: A dispenser for bulk goods comprises a storage container (11), and a discharge device connected thereto, a dosing means and a discharge chute (14) extending to a collecting point. The dosing means comprises a valve flap (18) which is pivotable between a closing position and a discharge position. An operating device (15, 27) is adapted to pivot the valve flap between said two positions. A locking device (34, 24) prevents the valve flap from pivoting from the closing position to the discharge position in the absence of a collecting receptacle or bag at the collecting point. Preferably, the operating device comprises two operating handles (15a, 15b), which are operatively connected to the valve flap (18) for pivoting thereof. In this operative connection, a sensor mechanism (27, 30, 31, 33) is included, which permits power transfer merely in essentially parallel or synchronous actuation of the operating handles.

Title: Vehicular rotary seat
Inventor: TAKENOSHITA TADASHI
IPC: B60N2/24
Filed: 1998-04-03
Abstract: With respect to a rotating seat for a vehicle, for example, for the elderly or the handicapped, the known art requires two operations of moving a seat body forward and rotating it to a door opening, and is thus poor in usability. Further, if the seat is positioned to the front such that the seat can be rotated at that position, the space close to occupant's feet is sacrificed. It is, accordingly, an object of the present invention to provide a rotating vehicle seat having excellent usability without sacrificing the space close to occupant's feet. A rotating vehicle seat of the present invention includes a rotating support base 10 for rotatably supporting a seat body 2, a longitudinal support base for supporting and moving the rotating support base in a longitudinal direction of a vehicle, and coupling means 6, 38 disposed between the seat body 2 and the longitudinal support base for coupling the rotational movement and the longitudinal movement of the seat body.
