Title: Mailing machine having a registration shield with improved air flow capability during ink jet printing on the envelopes
Inventor: BROSSEAU WILLIAM A
IPC: G07B17/00
Filed: 1998-10-16
Abstract: Mailing machine comprising a printer module including an array of ink jet print elements for printing on an envelope having a top surface, a registration shield located below and spaced apart from the printer module and a transport apparatus. The registration shield includes a top surface and a bottom surface and has an opening through which the array of ink jet print elements project ink onto the top surface of the envelope. The transport apparatus feeds the envelope in a path of travel so that the envelope passes between the registration shield and the printer module.  Additionally, the transport apparatus includes a device for biasing the top surface of the envelope into contact with the registration shield. The registration shield further includes a channel extending parallel to the path of travel and in substantial alignment with the opening so that the top surface of the envelope in proximity to the channel does not contact the bottom surface of the registration shield so as to allow air to flow through the opening.

Patent CA-2268566-A1 (CA)
Inventor: UCHINO HIROSHI
IPC: H02J3/18
Filed: 1999-04-09
Abstract: A series compensation generator SCG is installed in a transmission line that links various substations SS and the transmission capability of the system as a whole can be increased by regulating the equivalent reactance of the transmission line. Series compensation generator SCG generates a voltage of which the phase angle is shifted substantially 90° in relation to the current flowing in the transmission line, and it also generates a voltage that compensates the voltage drop due to the equivalent reactance.      Also, when an electrical fluctuation phenomenon (power oscillation) occurs in the transmission line, it is possible speedily to suppress the power oscillation by detecting the power fluctuation of the transmission line and controlling the compensating voltage of series compensation generator SCG so that it suppresses that power fluctuation.

Patent CA-2277180-A1 (CA)
Inventor: ESPENAN GREGORY D
IPC: A61K51/12
Filed: 1998-11-23
Abstract: Administration of a radioisotopic compound by infusion over a period of time greater than two hours, preferably greater than twelve hours, greatly increases the maximum radioactivity that accumulates in the target cell. The efficacy of the administration of the radiolabeled compound can be increased about five times higher than prior bolus injection or short infusion methods. This method enhances the tumor to background ratio by increasing the actual radioligand accumulated inside the tumor cells. This technique works for any radiolabeled compound whose cellular uptake is limited by a cellular process of either binding to a cellular receptor or to a transport protein. Once the radiolabeled compound is bound and internalized, the ability of an unlabeled compound to compete with the radioligand is markedly decreased. The primary factor governing residence time after internalization is the physical halflife of the radioisotope, not biologic half-life.

Title: Coal tar compositions
Inventor: BRZOZOWSKI KENNETH J
IPC: C08L95/00
Filed: 1999-07-16
Abstract: Improved coal tar compositions are described which are prepared from a blend comprising: (A) from about 80 parts to about 98 parts by weight of coal tar having an overall float test of from about 50 seconds to about 220 seconds, (B) from about 2 parts to about 20 parts by weight of coal tar pitch having a softening point of from about 140°C to about 160°C, and (C) from about 1 % to about 20% by weight, based on the total weight of the composition, of an acrylonitrile-butadiene copolymer. In one embodiment up to 35 parts by weight of the coal tar (A) is replaced with a coal tar selected from coal tars having softening points of from about 52°C - 60°C, and from about 56°C - 64°C.     The coal tar compositions are not emulsion, and generally will not contain any significant amount of water (e.g., less than 0.5% by weight). The invention also relates to a process for preparing the coal tar compositions which comprises the steps of: (A) preparing at an elevated temperature, a first mixture comprising (A-1) from about 80 parts to about 98 parts by weight of coal tar having an overall float test of from about 50 seconds to about 220 seconds, and (A-2) from about 2 parts to about 20 parts by weight of coal tar pitch having a softening point of from about 140°C to about 160°C, (B) maintaining the first mixture at a temperature of at least about 170°C, (C) adding to the first mixture, from about 1 % to about 20% by weight, based on the total weight of the composition, of an acrylonitrile-butadiene copolymer to form a second mixture and (D) mixing the copolymer into the second mixture.  The coat tar compositions of the present invention are useful particularly as roofing, waterproofing and maintenance materials. More particularly, the coal tar compositions are useful in built-up roofing (BUR) applications. The coatings formed from the coal tar compositions of the invention exhibit improved tensile, elongation and recovery characteristics, improved fatigue resistance, improved adhesive qualities, and improved cold temperature performance.

Title: Postcure treatment for reaction injection molded polyurethanes
Inventor: RETTMANN KENNETH J
IPC: B29C71/02
Filed: 1998-03-10
Abstract: A method of treating reaction injection molded polyurethane, polyurethane/urea and polyurea polymers comprising exposing a reaction injection molded polyurethane, polyurethane/urea or polyurea polymer to an amount of infrared energy sufficient to increase the temperature of the polymer to at least 180 ~C, and then maintaining the temperature of the polymer at or above that temperature, for a time sufficient to increase the Gardner impact property, as measured using ASTMD-3029, when compared to the same polymer which has been heated to the same temperature and maintained thereat for the same time in a convection oven. The invention produces marked improvements in impact, heat sag and heat distortion temperature properties, and thus is particularly suited to rapid preparation of parts using a mass production conveyor and is particularly well-suited to preparation of parts which are to be subjected to later high temperature processes, such as the "E-coat" process.

Filed: 1998-03-30
Abstract: An optical routing switch provides polarization-independent, low-crosstalk switching between input port (500) and plural output ports over a wide operating range of temperatures and wavelengths. Input signals are split into orthoganally-polarized beams by polarization dependent routing element (30). A  network of switches are placed along the paths. Each optical switch includes:  (1) a polarization rotator (100) that switchably controls the polarization according to the control state of the device; and (2) a polarization-dependent routing element (301) that routes the signals based on their state of polarization. Each output port in the network has an array of polarization rotators (90n) that provide polarization changes so that the beams become orthogonally polarized and a polarization depending routing element (60) recombines the signals.
Patent CA-2286966-A1 (CA)
Title: Differential pressure triggering device
Inventor: GAGNON MICHEL
IPC: H01H35/26
Filed: 1999-10-20
Abstract: The differential pressure triggering device has a housing having first and second adjacent inner chambers with respective pressure inlets. A pressure differential responsive diaphragm extends between the inner chambers. An iron disc is positioned inside the first inner chamber and is attached to the diaphragm so as to move along a predetermined displacement course as a result of a deflection of the diaphragm. A trigger unit is mounted outside the housing alongside the first inner chamber. The trigger unit has an actuator and a switch device responsive to a motion of the actuator for producing a triggering action. A magnet is attached to the actuator in magnetic interactive mobile arrangement with the iron disc so that a displacement of the iron disc resulting from a deflection of the diaphragm, causes a corresponding displacement of the magnet, thereby driving the actuator which operates the switch device.
