Patent CA-2190914-A1 (CA)
Inventor: STONER DAVID J
IPC: B65G29/00
Filed: 1996-11-21
Abstract: A rotary feed structure for a gunite-conveying machine includes a polymeric bodyto resist sticking of gunite even if the latter includes silica fume, and even if it has set. The body has chambers in a circle. Preferably the body is urethane, self-bonded to a Ni-hard wear plate to eliminate radial leakage, and the mounting means (typically holes for studs) are, at least in part, integral with the plate. A metal axial spacer is preferably next to the plate, but only within the innermost radius of chambers and with a sizable wall thickness. The body is preferably a feed-bowl type, with chambers formed as generally U-shaped pockets. A gunite machine using the polymeric feed structure also has a hopper, delivery tube, support and rotation of the feed structure, compressed-air for expelling the particulate material from the chambers into the tube, and provision for transporting the hopper, tube, body, and other apparatus. Chambers are selectively sealed to the expelling means and delivery tube. Dust emission is controlled by a short fill at the expulsion end of each chamber, and selective venting of residual pressure through the air-inlet end. Remaining dust, collected by a dry bag or atomizer nozzle, is preferably recycled to the bowl. New materials and procedures are used for fabricating the polymeric body.
Patent CA-2191987-A1 (CA)
Inventor: BARNES WILLIAM JOSEPH
IPC: F16B37/04
Filed: 1996-12-03
Abstract: According to the invention, the clip-on type fastener has first and second spaced apart legs which extend from a closed end to an open end operative to permit the installation of the fastener onto the edge of a panel member having an open ended slot in the edge thereof.  The first leg has a hollow tubular boss extending therefrom toward the second leg and having an abutment end face which is predeterminedly spaced from the first leg.  A thread engaging opening in the second leg registers with the hollow tubular boss so that the installation of a threaded fastener through the tubular boss and into the thread engaging opening causes the second leg to be drawn toward the first leg and into engagement with the abutment end face to thereby establish a predetermined space relationship between the legs for gripping the panel member therebetween.  The hollow tubular boss preferably has a diameter which corresponds closely to the size of the open ended slot of the panel member so that the tubular boss engages the panel member to locate the fastener on the panel member.  In addition, the second leg has a hood structure which extends integrally from the open end thereof, of a general "c" shape, beyond the end of the fastener, and terminates in close proximity with the closed end of the second leg to substantially shield the installed fastener.

Patent CA-2204217-A1 (CA)
Title: Atmospheric hazard detector network
Inventor: THOMSEN MARK H
IPC: G08B27/00
Filed: 1997-05-01
Abstract: A network of identical atmospheric hazard detectors communicates a locally sensed hazard condition directly to multiple neighboring detectors using RF command communication, without the use of wires and without a central control location.  Each detector includes a sensor of an atmospheric hazard, a detection circuit for measuring the sensor output and creating a local hazard signal, an alarm indicator, an RF transmitter for sending a neighboring hazard signal to the network, and an RF receiver for receiving a neighboring hazard signal from the network.  The local alarm and neighboring alarm control signals produce discernibly different alarm indications from the detector's alarm device, facilitating an attempt to locate the origin of a hazard.  In the preferred embodiment, every detector functions as a receive/transmit relay station, enabling the network to be extended in spatial expanse without limit and without increasing the power output of the RF transmitter.  Auxiliary devices are included, for example, a radio controlled light for emergency illumination.

Patent CA-2225228-A1 (CA)
Title: Multifold balloon for stent deployment
Inventor: FISCHELL DAVID R
IPC: A61F2/90
Filed: 1997-12-18
Abstract: Prior art balloons on balloon angioplasty catheters have two folds to wrap the balloon tightly around a distal portion of the balloon angioplasty catheter prior to balloon inflation. When using such a two-fold balloon to deploy a stent having (as is typical) more than three cells disposed circumferentially around each cylindrical segment of the stent, the cells of each segment frequently expand unevenly. That is, after balloon inflation some cells are expanded more than some other cells which is certainly undesirable. The present invention overcomes the disadvantages of prior art devices by utilizing a balloon with three or more folds to more evenly distribute the frictional forces on the inside of the stent during stent deployment thus improving the uniformity of stent cell expansion. Ideally one would like to have the same number of balloon folds as the number of stent cells distributed circumferentially around the stent. Matching the number of balloon folds to the number of cells of each cylindrical segment of the stent provides better size uniformity for the stent cells after they are expanded against the wall of an artery or some other vessel within a human body.
