Title: Interlock for transversely oriented circuit breaker switches
Inventor: FLEGEL DAVID D
IPC: H01H9/28
Filed: 1999-07-08
Abstract: An interlock for first and second circuit breaker switch mechanisms which respectively have first and second operating handles thereon oriented such that the direction of operation is transverse in relation to the other. The interlock includes an interlock mechanism disposed between the first and second switch mechanisms and includes a support, a first interlock member interconnected with the first operating handle, and a second interlock member interconnected with the second operating handle.  The first and second interlock members are mounted to the support for movement relative to each other along with the respective first and second operating handles. The interlock members include interference structure to prevent the second switch mechanism from being in an ON position when the first switch mechanism is in its ON position and likewise to prevent the first switch member from being in an ON position when the second switch member is in its ON position. The interlock mechanism allows both switch mechanisms to be in an OFF position simultaneously. The interlock mechanism may be used to prevent simultaneous delivery of electrical power from two alternate sources.

Patent CA-2280877-A1 (CA)
Inventor: SHARPLES MARTIN
IPC: C11D3/48
Filed: 1998-02-24
Abstract: The invention provides a hard surface cleaning composition of pH 3-11 comprising: a) 1-30 % nonionic surfactant, b) 0.005-5 % of a water soluble, anionic polymer having an average molecular weight of less than 1000000, said polymer being free of quaternary nitrogen groups, wherein, the ratio of polymer: nonionic is 0.1: 1 or less, and, c) 0.005-5 % of a cationic surfactant. It is believed that in the presence of the cationic surfactant, negatively charged (i.e. carboxylic dissociated) polymer can interact with the cationic surfactant and the nonionic surfactant to form a three-component complex which deposit the nonionic surfactant upon the soil and/or surface being cleaned. While the mechanism is not entirely clear, this may possibly be due to the interaction of the charged polymer with mixed miscelles of cationic and nonionic surfactant.

Title: Integration of low-k polymers into interlevel dielectrics using controlled electron-beam radiation
Inventor: HENDRICKS NEIL H
IPC: H01L21/312
Filed: 1998-03-09
Abstract: A process for the preparation of substrates used in the manufacture of integrated circuits wherein spin-on low dielectric constant (low-k) polymer films are applied on semiconductor substrates. A non-etchback processing of spin-on low-k polymer films, without losing the low dielectric constant feature of the film, especially inbetween metal lines, is achieved utilizing electron beam radiation. A polymeric dielectric film (7, 8) is applied and dried onto a substrate and exposed to electron beam radiation under conditions sufficient to partially cure the dielectric layer. The exposing forms a relatively more hardened topmost portion (8) of the dielectric layer and a relatively less hardened underlying portion (7) of the dielectric layer.

Inventor: CHAN MUN
IPC: H04L12/56
Filed: 1998-04-14
Abstract: For enhanced efficiency in setting up routes, and for enhanced throughput in an ATM network, invocation of objects can be parallelized. Also, throughput of a connection manager can be increased, and the latency of call set-up decreased by caching of network states such as recently used routes (504), output or input VCI/VPIs (506), bandwidth and buffer resources (507) and existing connection states (503). And the systems throughput can be increased by aggregating multiple request messages (505) into a single invocation instead of making multiple invocations.

Filed: 1998-07-17
Abstract: A system and method (Figs. 1-2) for dynamically optimizing occupied bandwidth of a direct modulated FM radio is disclosed, in which a remote receiver periodically monitors the received output of a local transmitter and compares the received output occupied bandwidth to a reference level. If the monitored level of the demodulated signal unacceptably exceeds the reference level an error mesage is developed and sent back to the local transmitter to cause the output of the local transmitter to be adjusted to more closely conform to the desired spectrum output mask. An alternative embodiment (Fig. 4) is also disclosed in which temperature and operating frequency are monitored at the local transmitter and a correction factor appropriate for that operating temperature and frequency are applied.
Patent CA-2296788-A1 (CA)
Inventor: MCCALL MARK S
IPC: H01R4/66
Filed: 2000-01-21
Abstract: The invention provides a cable-securing and grounding device that simplifies installation and grounding of shielded cable within an enclosure housing an optical networking unit. The device has two shells or housings that fit together to form a casing having openings through which a cable such as a combined optic-fiber and power cable run. Two sets of teeth within one housing engage the cable, one set made of a metal and touching the shield and the other set touching the outer jacket of the cable. A pressing surface within the other housing presses the cable at approximately the mid-point between the two sets of teeth. The combined action of the teeth and the pressing surface hold the cable in place. A threaded portion of the device is inserted through a hole in the enclosure, and a metallic nut secures the threaded portion to the enclosure. The metallic teeth within the device conduct electricity from the cable's shield through one of the metallic housings and through the metallic enclosure and to ground. This configuration eliminates the need for a separate ground wire that attaches to the cable's shield and to a ground lug within the enclosure, and simplifies installation by reducing the time and effort required to secure and ground a cable.

Patent CA-2304016-A1 (CA)
Inventor: POHJANVUORI TIMO
IPC: H04H60/94
Filed: 1998-09-14
Abstract: The above-mentioned objects are achieved in accordance with the invention by a method for transferring information from an information provider (100) to an information consumer (190) in a highly efficient manner by means of a digital audio broadcasting (DAB, 140) system and a secondary bidirectional transfer network (130). The secondary network provides information of where the DAB  receiver (191) of the information consumer is located so that only suitable DAB transmitters (146) in the area are used for the information transfer itself. The location is determined by having at least one transmitter identification information (TII) of one transmitter that the receiver can receive transferred via the secondary network. Thereby only the necesary DAB  transmitters need to be used for the information transfer, thus relieving the rest of the DAB transmitters (145, 147) from an unnecessary downloading.
