Patent CA-2189933-A1 (CA)
Title: Precompression pump sprayer
Inventor: MONTANER PEDRO P
IPC: B65D83/76
Filed: 1996-11-08
Abstract: A precompression pump sprayer of the type having main and secondary pump cylinders and pistons has a two- piece main piston assembly comprising a separate piston sleeve element of molded compliant material and a hollow piston stem of molded rigid material affixed thereto. The more rigid stem permits a reduction in its overall height and overall diameter, resulting in a reduction of the overall height of the pump sprayer.

Title: Apparatus and method for transurethral focussed ultrasound therapy
Inventor: ANDRUS WINFIELD SCOTT
IPC: A61F7/00
Filed: 1996-11-13
Abstract: An apparatus and method for the treatment of diseases of the prostate, including BPH and prostate cancer, utilizing transurethrally applied focussed ultrasound energy to produce hyperthermal and thermotherapeutic effects in diseased tissue are disclosed. A first preferred embodiment of the apparatus relies on visual control; and a second preferred embodiment of the apparatus incorporates an integrated ultrasonic imaging and therapy transducer. The apparatus and method feature the close proximal placement of the ultrasound transducer to the diseased tissue to be treated, resulting in less attenuation of the beam and deposition of a greater fraction of the total emitted ultrasound energy in the selected portion of the diseased tissue. The ultrasoundenergy passes atraumatically through the urethral wall and other tissue not targeted. At the focal point of the ultrasound energy, substantial heating of diseased tissue to produce hyperthermal effects therein occurs, and even higher thermotherapeutic temperatures are attainable to produce coagulative necrosis of diseased tissue.
Patent CA-2191005-A1 (CA)

IPC: H02H3/33
Filed: 1996-11-22
Abstract: A ground fault protection electrical outlet with miswiring indication includes, besides a main outlet unit that includes a housing, a primary and a secondary pair of first and second electrical connectors accessibly arranged on the housing, two main switches respectively interposed between the first, and the second, connectors of the primary and secondary pairs and simultaneously switchable between their open and closed positions, and at least two electrical contacts located at the same side of the switches as the secondary connectors, an indicator circuit built into the main outlet unit and operative for indicating a miswiring situation in which the wires of a wire pair that supplies electrical current to the outlet unit are mistakenly connected to the connectors of the secondary pair. The indicator circuit includes a current-limiting resistor, an indicator device operative for emitting a discernible warning of the miswiring situation, and an auxiliary switch switchable between its open and closed states, all interposed in series in an electrical path permanently joined with the secondary connectors. The auxiliary switch is ganged with the main switches in such a manner that it is open when the they are closed so that no current can flow through the indicator device even if the miswiring exists, and closed when the main switches are open so that electric current can flow through the closed auxiliary switch and also through the indicating device to activate the latter but only in the event of the miswiring.

Title: Active harmonic filter and power factor corrector
Inventor: SHERO DAVID J
IPC: H02J3/01
Filed: 1997-08-08
Abstract: An active harmonic filter selectively sources current to or draws current from power lines. The active harmonic filter includes a controller which executes a predictor routine which predicts the current to be supplied to or drawn from the power line at a time t+.DELTA.t to reduce load induced phase differences between the line voltage and the line current. An integrating slow control routine integrates difference currents between actual line currents and desired line currents in equivalent segments of time in different cycles of the power line. The integrated differences may be combined with proportionally controlled difference currents to reduce or eliminate harmonic line currents. A current balancing routine enables the active harmonic filter to balance currents in two or more lines of a polyphase power line. The predictor, integrating slow control and current balancing routines, may be used singly or in combination to improve the condition of line currents on the power lines.

Filed: 1996-03-20
Abstract: A cellular telecommunications system has a plurality of nodes, each for performing at least one of a number of cellular telecommunications system functions, including base station, speech coder, control processing, signal processing, local handoff, location register, and network interface functions. The nodes are interconnected by a network preferably comprising an optical fiber cable. In one aspect of the invention, the protocol that is used on the network is a high speed synchronous protocol, such as the DTM protocol.  A first node in the system may be an antenna; an RF component coupled to the antenna; an analog-to-digital converter having an analog port, and a digital port being coupled to the RF  component; and an optical fiber modem for connecting the digital port of the analog-to-digital converter to the network means. A second node in the system may be for performing base station controller functions, wherein the first and second nodes, together, operate as a distributed base station. In another aspect of the invention, some of the nodes may be transceivers, while other nodes include antennas coupled to frequency band filters. The network operates to permit any of the transceivers to be coupled to any one or more of the antennas, thereby permitting a handoff of a call from one antenna to another while maintaining use of the same transceiver, or permitting a handoff of a call from one transceiver to another while maintaining use of the same antenna.
