Patent CA-2308788-A1 (CA)
Title: Multiple part manual dispensing syringe
Inventor: MORRIS DAVID PAUL
IPC: B65D81/32
Filed: 1998-10-16
Abstract: A syringe (10) includes a tube (12) defining a chamber (16) with a dispensing opening (18). A plunger (20) is slidably mounted in the tube and is initially positioned at the end (24) of the chamber opposite the dispensing opening. A dasher (26) having an opening (34) is positioned within the chamber at an intermediate point. A cylindrical barrier (40) is detachably secured to the dasher (26). Thus, with the barrier secured to the dasher, the barrier and dasher sealingly engages the tube dividing it into two subchambers (44, 46). An elongated rod (52) extends through openings (54, 56) in the plunger and the barrier and is secured to the dasher. Rotation of the rod detaches the barrier from the dasher establishing communication between the subchambers. A locking sleeve (62) frictionally secures the rod and the plunger together when the rod is moved to a retracted position (Fig. 4). Furthermore, optionally the rod is hollow (Fig. 9) and defines a third subchamber (80) containing a third liquid.

Patent CA-2322503-A1 (CA)
Title: Disposable absorbent article having a skin care composition containing an enzyme inhibitor
Inventor: ROURKE FRANCIS JAMES
IPC: A61K36/48
Filed: 1999-03-11
Abstract: The invention provides an absorbent article, at least a portion of which comprises a skin care composition that comprises an enzyme inhibitor and is at least partially transferred from the article to the skin of a wearer of the article as a result of normal contact, wearer motion and/or body heat. The enzyme inhibitor is transferred to the skin with the skin care composition and is available at the skin/urine and skin/feces interfaces to inhibit enzymatic activity on the skin and to reduce or prevent the occurrence of inflammation.  Repeated application of similar treated articles to the wearer's skin provides an available source with which the enzyme inhibitor transfers onto the skin continuously over time and accumulates to provide a proactive defense against harmful enzymes for the treatment and/or prevention of diaper dermatitis.

The axis i s rotated and a histogram is formed of the pixels projected onto the rotated axis until the histogram includes charateristics indicating that the line is  most closely perpendicular to the rotated axis. In a process of detecting a line on a road, an image is acquired of the road, and pixels of the image having characteristics corresponding to characteristics of the line are selected. A histogram is formed of the selected pixels projected onto an axi s. The axis is rotated and a histogram formed of the selected pixels projected onto the rotated axis until the histogram includes characteristics indicativ e of a line. In a process of detecting a lane on a road having left and righ side lines, pixels of the image in a first area of the image at a first orientation and pixels in a second area of the image at a second orientation  in the image are selected for selecting pixels associated with the lines. Histograms are formed projected on the first and second axes, respectively, and the axes are rotated until each histogram includes characteristics of a line. Also disclosed is a process of detecting a vehicle in an adjacent lane , systems for performing theaforementioned processes, systems for identifying an object and an input signal, and an interface between an image processing system and a controller.

Abstract: A method is provided for making mirrors having enhanced reflective layer resistance to corrosion. The reflective layer of the mirror, typically silver, is contacted, preferably simultaneously, with a first solution containing a specific cation and a second solution containing a specific anion, or alkaline material which forms hydroxyl ions, the specific cation and specific anion or hydroxyl ion reacting to form a water insoluble precipitate on the silver surface. The mirror may then be painted to provide additional corrosion resistance to the mirror.  The method eliminates the need for a copper layer on the silver surface and the method may be incorporated into existing mirror production lines as a replacement for the copper layering step. Also provided are an apparatus for making the mirrors and the mirrors made using the method and apparatus of the invention. A preferred cation containing solution contains tin (e.g., SnCl2) and a preferred anion containing solution contains hydroxyl ions (e.g., NaOH).
