Patent CA-2135534-A1 (CA)
Title: Tape splicing device
Inventor: CAIRNS JOHN
IPC: B65H19/18
Filed: 1994-11-10
Abstract: Currently available corrugated carton sealing machines utilize a pair of taping heads, each of which carries a roll of pressure sensitive tape.  When a roll of tape is finished, it is necessary to stop the machine and replace the roll with a resulting loss in production time.  A simple solution to the problem is provided by the tape splicing device described herein which includes a bracket for mounting on a sealing machine frame, a shaft rotatably mounted on the bracket, the bracket carrying a spindle on each end thereof for a roll of tape, a first handle and brake on one end of the shaft for releasably locking the arm in one position, and a second handle on the other end of the shaft for rotating the shaft and arm, a wiper roller and a separation roller mounted on the frame.  A first roll of tape is dispensed from one spindle to a taping head, and a second, fresh roll of tape is placed on the other spindle.  When the first roll of tape is almost completely dispensed, the brake is released and the arm is rotated to bring the second roll of tape into contact with the adhesive surface of the first roll.  Continued rotation of the arm causes the first roll to wrap partially around the second roll, whereby a paper tab on the leading end of the second roll is attached to the first roll of tape to start dispensing of the second roll of tape in overlapping relationship with the trailing end of the first roll of tape.          The arm is rotated until the used roll passes between the wiper and separation rollers, whereby the trailing end of the used roll engages the separation roll and the new roll engages the wiper roll.  The arm is again locked in position and the trailing end of the old roll of tape is cut.  The resulting flap of old roll tape is pressed against the new roll to complete the splice and dispensed with the new roll tape to the taping head.

Patent CA-2144581-A1 (CA)
Title: Method and system for hot air spray coating and atomizing device for use therein
Inventor: HYNDS JAMES E
IPC: B05B12/00
Filed: 1995-03-14
Abstract: A  spray  gun  uses  hot,  high  volume,  low pressure (HVLP) air to atomize a coating material at a spray head of the gun.   The coating material may be water-based  adhesive  or paint  which may  include  a relatively small amount of solvent.  The coating materi-al may also be a high viscosity, solvent-based paint such as a polyester or urethane.  The spray gun includes a plunger mechanism and a trigger which generate an air pressure control signal which opens a valve to allow the hot HVLP air to come to the front of the spray gun. Thermally insulated hot air hoses couple the spray gun to a source of hot air such as a heater conversion unit. Teflon tubes thermally insulate the coating material from the hot air as the coating material is received by the spray gun.  A plastic shroud thermally insulates and concentrates a hot air coating material mixture during atomization of the coating material at a spray head of the spray gun.   The hot air has a temperature in the range of 250°F to 350°F at the spray head so that a substantial portion of the base of the coating material is evaporated from the atomized coating material before coating an article.   When the coating material is a water-based adhesive, the water-based adhesive dries in about the same amount of time that it takes  for a solvent-based adhesive to dry in a conventional spray coating system.

Patent CA-2153137-A1 (CA)
Inventor: TAILLON ARMAND P
IPC: B61F5/12
Filed: 1995-06-30
Abstract: A novel friction wedge for use in a bolster pocket of a truck of a railroad car, comprises a metal body portion having a vertical wall and one or more pad members supported on the surface of a pad-support body. The metal body portion has a vertical wall the exterior surface of which body bears against a guide column of the side frame. The pad-support body, which is part of the metal body portion, is provided with an inclined surface upon which is secured a polymer pad with a central planar inclined surface which bears against the correspondingly inclined surface of the pocket. The pad member is required to be formed from specified reaction injection molded (RIM) polymers which it is found to be free of microscopic voids > 20µm and therefore, fully dense, unlike prior art polymer pads for friction wedges. This property of being fully dense unexpectedly allows the pad to have specified physical properties which permit a railroad car truck equipped with the friction wedges to operate with exceptional reliability, safety and for a long period of time. In a particular embodiment, the design of the pad(s) permits relative movement of the pad and the metal body of the friction wedge to locate the center of pressure accurately on the friction wedge, under load, and this further improves the effectiveness of the friction wedge and extends its useful life.

Title: Delivery of gene products via mesangial cells
Inventor: KITAMURA MASANORI
IPC: A61K35/12
Filed: 1994-11-14
Abstract: Disclosed are methods that achieve i) site-directed delivery, ii) in situ amplification, and iii) sustained expression of an exogenous gene product within renal glomeruli. An exogenous gene, <u>E. coli</u>.beta.-galactosidase, was introduced into cultured rat mesangial cells using a replication-defective retrovirus, and stable infectants were administered to a rat kidney via the renal artery. In the injected kidney, the engineered, cultured mesangial cells populated 40 % of glomeruli site-specifically. The gene product was detected throughout a 14-week period of observation. In an alternative method, engineered, cultured mesangial cells were injected into a kidney subjected to an antibody that induces mesangiolysis followed by mesangial regeneration.  Under these conditions, expression of .beta.-galactosidase was dramatically amplified <u>in situ</u>, and high level expression continued for at least 8 weeks.
