Patent CA-2232690-A1 (CA)
Inventor: BOCHENEK JEFFREY
IPC: H02P7/03
Filed: 1996-09-17
Abstract: An electrical circuit for a switch having a lockout feature is described. The circuit permits both a primary operator and an auxiliary operator to operate a bi-directional motor (30) by activating separate low-current switches (SW1, SW2, SW3, SW4). The circuitry enables the primary operator to disable the auxiliary operator's ability to operate the motor by activating a lockout switch (L/O). With the lockout switch activated, the primary operator can operate the motor without interference from the auxiliary operator. High-current power switches (50, 52), activated via logic circuitry (70, 90) rather than by the operators, are used to complete a power circuit for energizing the motor.

Title: Conversion of a permanent connection into a signalled permanent connection and vice versa
Inventor: BOSLOY JONATHAN L
IPC: H04Q3/00
Filed: 1998-12-04
Abstract: A method of converting a permanent connection, such as a PVC, into a signalled permanent connection, such as an S-PVC, in a connection-orientated network, such as an ATM network, without service disruptions. The method includes the steps of: (a) establishing signalling links between each network node along the path of the permanent connection; (b) providing information to identify the cross-connections along the path; (c) incorporating the cross-connect identification information in a call set-up message; (d) signalling the call set-up message along the path from a source network node to a destination network node; and (e) associating the cross-connection of each node along the path with the appropriate signalling links in order to form the signalled permanent connection. The cross-connect identification information may be a unique call identifier for the permanent connection, in circumstances where the call identifier is associated with the permanent connection cross-connections prior to Step (d). Alternatively, the cross-connect identification information may be a permanent connection path definition specifying each cross-connection is the path. A  similar method for converting a signalled permanent connection into a permanent connection is also disclosed.

Title: Process for producing a polymer by polymerization of a monomer having an ethylenic double bond
Inventor: NOGUKI GENJI
IPC: C08F2/00
Filed: 1999-02-03
Abstract: An improved process for producing a polymer by polymerizing a monomer having an ethylenic double bond in a polymerization vessel having a polymer scale preventive coating film on its inner wall surfaces, etc. is provided. The coating film is formed by coating a first coating liquid containing a compound selected from the group consisting of an aromatic compound having 5 or more conjugated .pi. bonds and a heterocyclic compound having 5 or more conjugated .pi. bonds, and then coating a second coating liquid on the first layer. The first and second coating liquids are applied by means of steam as a carrier. The second layer has a surface having a contact angle to water of less than 60° after its surface has been brought into contact with a solution of mixture of water and a vinyl chloride monomer in a weight ratio of 1:1, at 50°C for 1 hour. This process can shorten the time for forming the coating film to improve productivity, can improve the effect of preventing adhesion of polymer scale, can make colored particles less mix into polymer products obtained by this process, can lessen fish eyes and initial discoloring of formed products and can improve the quality of polymeric products and their formed or molded products.

Inventor: CHEN PHANG-LANG
IPC: C07K14/435
Filed: 1997-12-17
Abstract: The protein encoded by the human gene HEC(highly expressed in cancer) contains a long series of leucine heptad repeats and appears to be crucial for normal mitosis. HEC localizes to the nuclei of interphase cells and redistributes to centromeres during M phase. Ectopic expression of a mutant HEC containing only the heptad repeats results in the inability of cells to divide more than once. Inactivation of HEC results in disordered sister chromatid alignment and separation, as well as in the formation of non viable cells with multiple, fragmented micronuclei. HEC interacts through its leucine heptad repeats with several proteins involved in mitosis, including nek2, sb1.8, and two different regulatory subunits of the 26S proteasome, MSS1 and p45. These biochemical properties of HEC suggest its potential roles in modulating proteins important for spindle attachment to kinetochores, sister chromatic movement, and M phase progression.
