Patent CA-2145160-A1 (CA)
Title: Gas blending system
Inventor: KNIGHT LARRY F
IPC: B01F23/10
Filed: 1995-03-21
Abstract: A tracer gas line and a carrier gas line are used to provide a tracer gas, such as helium, and a carrier gas, such as nitrogen, for blending. A back pressure controlling regulator is positioned in the tracer gas line and is controlled by a signal from the carrier gas line, so that the tracer gas pressure matches the carrier gas pressure under varying carrier gas flow and/or downstream pressure conditions. The two gas lines are piped to a common discharge manifold, and contain valves or orifices adapted to maintain the same carrier and tracer gas flow proportions independent of changes in carrier flow or pressure.

Patent CA-2148070-A1 (CA)
Inventor: JULNES JON N
IPC: E01F9/04
Filed: 1995-04-27
Abstract: The present invention is characterized as methods for fixedly depositing solidified protrusions on to a surface, and products thereof so as to create a detectible warning whereby the tactile and visual characteristics of the detectible warnings contrast with the tactile and visual characteristics of surrounding surfaces. To create such a detectible warning, a mask in the form of a resilient mat is perforated with a plurality of apertures so as to form a repeating pattern. Each aperture acts as a mold of a protrusion having predetermined dimensions. To enhance the functionality of the protrusions, each protrusion has a generally inclined peripheral surface and rounded peripheral surface to substrate and peripheral surface to upper surface interfaces. The mat is placed in contact with the substrate on which a detectible warning is desired. A blend is created from a curable viscous substance and one or more of the following: reinforcing elements, reflective elements, pigments, or abrasives. The blend is then worked into the apertures whereupon it begins to solidify. After the blend becomes semi-stable, the mat is removed and the protrusions are allowed to fully cure.

Patent CA-2181838-A1 (CA)
Inventor: MORRA JOSEPH ANTHONY
IPC: F23D3/24
Filed: 1996-07-23
Abstract: In a device for holding a wick for an liquid oil lamp, in a bottle, it is known to have a stem with a vertical hole varying in size such that an appropriate wick, used to draw up the liquid oil, can be threaded through the vertical hole, such that the wick is held in place because of the friction which is present between the wick and the wall of the vertical hole. This device is known to have a flared top with a larger diameter than the bottle neck opening such that flared top prevents the device from falling into the bottle. In this invention, a groove is made in the bottom of the stem such that a non-reactive flexible washer of an appropriate thickness and diameter can be installed and retained. The device, with this washer installed in the groove, will form a seal between both the inside of the groove and with the inside of the bottle neck opening. Also in this invention, a channel is made in the flared top. This enables a fragranced oil to be placed in the channel, via a dropper and/or pipette.
