Patent CA-2181786-A1 (CA)
Title: Improved chip feed system and method for a digester
Inventor: BILODEAU VICTOR L
IPC: D21C7/02
Filed: 1995-11-28
Abstract: In a continuous digester system, the chip feed equipment is greatly simplified by substituting a single vertical vessel for the conventional chip bin, steaming vessel and chip chute. An outlet at the bottom of the single vessel is connected, through a low pressure pump, to the low pressure input of a high pressure transfer device which is connected to a digester (either directly or through an impregnation vessel). A metering device, preferably through a pressure isolation device for maintaining superatmospheric pressure in the vessel, feeds chips into the top of the vessel. A first level of chips is established in the vessel, and a second, liquid, level below the first level is also established. Steam is supplied to a volume between the top of the vessel and the second level utilizing a conduit with an automatically controlled vale and a temperature controller for at least partially controlling the valve. A level controller controls the supply of liquid to the vessel and is connected to the low pressure outlet from the high pressure transfer device. There is a reduction in cross-sectional area of the vessel of greater than 50% between the second level and the outlet at the bottom of the vessel. Alternatively, the pump from the bottom of the vessel may be connected to one or more batch digesters.

Title: Uterine endometrial tissue sample brush
Inventor: TAO LIANG-CHE
IPC: A61B10/00
Filed: 1996-09-11
Abstract: A uterine endometrial tissue sample brush includes a flexible core having a distal core end and a cylindrical brush member carried adjacent the distal core end. The core is formed from a spirally wrapped pair of wires and includes an atraumatic tip. The brush member is about 3 to 5 cm long and has a free outside diameter, preferably about 5.08 to 7.62 mm (0.2 to 0.3 in.), suited to maintain patient comfort yet comprehensively contact the undilated uterine canal. The brush member includes a plurality of resilient bristles axially spaced about 0.5 .to 1.5 mm apart. The bristles have a stiffness equivalent to that possessed by nylon-6,12 at a diameter of about 0.076 to 0.152 mm (0.003 to 0.006 in.). This stiffness is critical and unexpectedly gives the brush good exfoliating and collecting abilities simultaneously, in contrast to prior devices which may possess either good exfoliating or good collecting abilities, but not both abilities at the same time. The bristles are preferably composed of nylon-6,12 of about 0.127 mm (0.005 in.) diameter, and are retained between the pair of wires so that they are spirally arrayed. The brush also preferably includes a flexible sheath adapted to slidably receive the core and brush member therein, to prevent the collection of undesired exocervical or vaginal fluid or material during introduction or removal of the brush. The brush especially useful for routinely and repeatedly collecting samples for cancer screening or for monitoring ongoing estrogen replacement therapy.

Title: Synchronous polarization and phase modulation using a periodic waveform with complex harmonics for improved performance of optical transmission systems
Inventor: BERGANO NEAL S
IPC: G02F1/01
Filed: 1996-12-23
Abstract: A method and apparatus is provided that yields improved performance by modulating the optical phase and polarization of an optical signal with a periodic waveform having harmonic content that is more complex than that associated with a simple sinusoidal waveform.  A phase modulator receives an optical signal onto which data has been modulated at a predetermined frequency.  The phase modulator modulates the phase of the optical signal in a continuous manner with the periodic waveform with complex harmonics where the fundamental phase modulation frequency is equal to the same predetermined frequency at which the data is modulated onto the optical signal.  In another illustrative embodiment of the invention, a polarization modulator further processes the optical signal by modulating the state-of-polarization of the signal in a continuous fashion with the periodic waveform with complex harmonics where the fundamental polarization modulation frequency is equal to the same predetermined frequency at which the data is modulated onto the optical signal.  In addition to being continuously modulated, the polarization modulation is performed so that the average value of the state of polarization over each modulation cycle is substantially equal to zero.
