Title: Digital button telephone system and extension terminal for the same
Inventor: TANAKA TOSHIAKI
IPC: H04M3/22
Filed: 1997-02-13
Abstract: According to this invention, a digital key telephone system connected to an analog public network NW having a function of transmitting a ringing signal including identification information of a calling line through a subscriber line (CO line), accommodating a plurality of extension lines each connected to a digital key telephone (DKT) 2 or a standard telephone (STT) 4 as an extension terminal, and having a function of switching and connecting the subscriber line to the plurality of extension lines or the extension lines to each other includes a called party storage means storing, in advance, information representing the correlation between the calling line and the extension terminals 2 and 4 as a called terminal. When a ringing signal arrives from the analog communication network NW, calling line identification information (caller ID) contained in the ringing signal is detected by a calling line identification information interface unit (RCIU) 12. A control unit (RCTU) 16 determines the called extension terminal on the basis of the detected caller ID and the information stored in the storage means, so the extension terminal receives the call from the digital key telephone interface unit (RDKU) 13 or a standard telephone interface unit (RSTU) 15.

A single-piece inboard head seals the pump chamber and the motor housing and spaces the pump chamber away from the motor. Removable flame arrestor assemblies are attached to the inlet and outlet ports into which the vapor is, respectively, drawn into and exhausted from. A gland assembly integral with the motor housing provides a seal around the conductors that extend to the motor.
Patent CA-2247688-A1 (CA)
Title: Composite heat sink
Inventor: GOSSETT KEITH ALAN
IPC: H05K7/20
Filed: 1998-09-21
Abstract: The present invention is a heat sink with a heat transfer medium for enhancing the heat transferring ability of the heat sink. In one embodiment, the heat sink comprises a plurality of fins with cavities, a base and a fluid heat transfer medium. The fins are in thermal contact with the base and configured to form a series of longitudinal channels through which air or a fluid medium may pass. The fluid heat transfer medium contained within each of the cavities. The fluid heat transfer medium enhances the heat sink's ability to transfer heat without increasing its surface area, size and/or weight. This enhancement is due to the fluid heat transfer medium's latent heat of vaporization and condensation. Specifically, a larger amount energy is required to vaporize the fluid heat transfer medium. Thus, a large amount of heat can be conducted from the base to the fluid heat transfer medium. Conversely, as the vaporized fluid heat transfer medium condenses on the upper cooler walls of the fins, a large amount of energy is conducted from the vaporized fluid heat transfer medium to the fins. Thus, a larger amount of heat can be conducted from the fluid heat transfer medium to the fins which can then dissipate the heat to lower temperature surroundings.
Patent CA-2248335-A1 (CA)
Inventor: GERSTENKORN BERNHARD
IPC: G05B9/02
Filed: 1998-09-22
Abstract: This monitoring equipment (1) for a drive control for lifts consists substantially of two modules, a safety circuit sensor system (2) and a motor-switching and/or brake- switching circuit (3), wherein the monitoring of a safety circuit (4) and the consequential actions resulting therefrom takes place exclusively by means of electronic components whilst avoiding electrically conductive separating locations. By the use of electronic components, electromechanical switching elements, which have electrically conductive separating locations, can be dispensed with. In addition, an appreciable reduction in the noise level is achieved, since switching noises no longer arise. This has an advantageous effect particularly in the case of lift installations without machine room. Furthermore, the manufacturing costs can be significantly reduced and a high security and reliability of the monitoring equipment (1) can be ensured by the use of usual electronic components.

Title: System and method for implementing local number portability
Inventor: EPLEY ROBERT V
IPC: H04Q3/00
Filed: 1997-10-30
Abstract: A system and method for routing communications to a terminating station associated with a porting subscriber directory number when the porting subscriber line (14a) is cut-over from a donor switch (12a) to a donee switch (12b). Upon cut-over of the porting subscriber line (14a), a local number portability (LNP) activation telephone call is placed to a dial-in platform (50) that activates a previously provisioned but inactive LNP database entry for the porting subscriber directory number. The LNP database entry is located in an LNP database (42a) at a service control point (SCP) (28a). The dial-in platform (50) also activates a previously provisioned but inactive directory-number-level trigger for the porting subscriber directory number at the donor switch (12a). Activating the directory-number-level trigger for the porting subscriber directory number at the donor switch (12a) causes the donor switch (12a) to hold a subsequently received telephone call directed to the porting subscriber directory number. The donor switch (12a) then transmits a query message to the SCP (28a) and holds the telephone call until it receives a response message including routing instructions from the SCP (28a). Activating the LNP database entry for the porting subscriber directory number in the LNP  database (42a) at the SCP (28a) associates the porting subscriber directory number with the donee switch (12b). Activating the LNP database entry therefore allows the SCP (28) to determine the correct terminating switch for the held telephone call, which after cut-over, is the donee switch (12b).
