Patent CA-2242575-C (CA)
Inventor: WELCH DAVID F
IPC: H01S3/131
Filed: 1997-01-10
Granted: 2001-12-11
Abstract: Two approaches are provided for achieving an optical amplifier system capable of producing high peak power, high energy pulse outputs while suppressing scattering noise. The first approach relates to an optical amplifier system which has at least one laser diode pulsed or cw pumped double clad fiber amplifier utilized for receiving a high frequency modulated injected signal pulse of short duration from the laser diode, via the fiber core, for amplification by coupling pump light into the inner cladding of the fiber. The average signal power is sufficient to saturate the gain of the fiber so as to minimize significant onset and buildup of forward and backward scattering noise. The duty cycle of the injected signal source pulse is chosen to allow adequate gain recovery in the fiber amplifier between pulses. The second approach relates to a cascaded optical amplifier system having at least two optical amplifying stages with two pulsed pump sources provided and two amplifying media, the first of which receives the injection and at least one pump signal wherein the injection pulsed signal is amplified to a first power and energy level. The second amplifying medium, optically coupled to the first, amplifies the first level signal to a second level amplified, injection pulsed signal. The duty cycle of the injection pulsed optical signal is synchronized with the first and second pulsed pump signals with the first pulsed pump signal having a different duration in the duty cycle than the second pulsed pump signal.

Abstract: It is intended to provide a swash plate type continuously variable transmission capable of automatically affording a lock-up state in which second distributing valves are stopped at their stroke mid-point to cut off motor ports when a motor swash plate stands upright, even without using any special interlocking mechanism. Second distributing valves for bringing motor ports of motor cylinder bores into communication with a high-pressure oil path and a low-pressure oil path selectively in an alternate manner are arranged in parallel with the axis X of a cylinder block; a valve swash plate for reciprocating the second distributing valves is integrally combined with a motor swash plate on the same slant plane; and the motor ports are formed so as to be controlled selectively by the second distributing valves at respective positions 90° out of phase in the in circumferential direction of the cylinder block 4 with respect to the corresponding motor cylinder bores, the second distributing valves being stopped at their stroke mid-points when the motor swash plate stands upright. In a swash plate type hydraulic unit for use as a swash plate type oil-hydraulic pump or motor, it is intended to attain the reduction in redial size of the hydraulic unit while ensuring a sufficient plunger stroke.0

Granted: 2001-07-24
Abstract: In one embodiment, the invention provides a drilling assembly comprising a motor, a reaming stabilizer and a drill bit. The motor is adapted to be attached to a drill string, the motor includes a drive shaft with a mandrel mounted at the bottom end of the shaft.  The reaming stabilizer is attached to the shaft of the motor by the mandrel, so that the stabilizer may be rotatably driven by the motor. The drill bit is attached to the stabilizer to be rotatably driven by the stabilizer. The stabilizer is sized so that the overall length of the drilling assembly is increased by a maximum of about 16 inches. Greater lengths may reduce motor bearing life, adversely affect the steering of the tool or result in drive shaft breakage with consequent loss of the drill bit and stabilizer in the hole.

Title: Terminal seal for electrolytic devices
Inventor: LING PETER
IPC: H01M50/172
Filed: 1998-12-23
Granted: 2003-01-07
Abstract: A terminal assembly for sealing and electrically isolating a conducting terminal from a container of an electrolytic device uses a lock nut and a single-piece deformable gasket. When the lock nut is threaded down the terminal, an inwardly tapered sleeve of the lock nut cooperates with an outwardly tapered zone of the gasket to force the gasket to surround the opening of the container and to seal the terminal before compression is applied. Reliable sealing and electrical insulation are provided because predetermined axial and radial compression forces are generated on the opening of the container. A robust sealed terminal is provided while over compression of the single-piece gasket is prevented.

Abstract: A surgical method and apparatus for accurately aligning the trajectory of, guiding of, and introducing or withdrawal of an instrument is disclosed. The apparatus includes a base which has a movable member movably attached to the base. The movable member has a passage therein which forms a portion of the trajectory path. A positioning stem further includes a first locator and a second locator. The first and second locators are associated with two different portions of the positioning stem so that they are essentially two points on a line. The first and second locators are also locatable by a scanning or imaging system. The positioning stem is removably attached to said movable member and used to position the movable member. Moving the movable member also moves the passage therein to different trajectories. Once the passage within the movable member more or less is aligned with a target within the body, a locking member locks the movable member into a fixed position. The movable member can be moved to different trajectories using a first hydraulic system. A second hydraulic system can be used to introduce or withdraw an instrument to or from the patient. A mechanical advancement tool can be substituted for the second hydraulic system. The surgical instrument may also be provided with a remote portion for controlling the instrument from a remote location. The instrument can also be computer controlled.

Granted: 2013-02-12
Abstract: The present invention is directed to immortalized STAT1-deficient mammalian cell lines. STAT1 is a signal transducer and activator of transcription that becomes phosphorylated when cells are treated with type I or type II  interferons and leads to induction of specific gene expression, resulting in establishment of the antiviral state and the other known biological responses to interferons, including the inhibition of cell proliferation. Cells which lack this gene product are useful for producing high titers of viral stocks, for producing recombinant viral vectors, for testing samples, especially clinical samples for the presence of virus and for screening candidate compounds or drugs for anti-viral activity.
