Title: Emulsifier-free carboxylated nitrile rubber latex
Inventor: MULLER PASCALE FRANCINE JEANNE
IPC: C08F236/12
Filed: 1999-04-26
Abstract: Carboxylated nitrile rubber latices are used in a wide variety of industrial applications, such as in the manufacture of gloves, non-woven fabrics, masking tape and an array of other products. Carboxylated nitrile rubbers are conventionally synthesized by emulsion polymerization. The need for an emulsifier in the synthesis of carboxylated nitrile rubber can be eliminated by practicing the process of this invention. The present invention more specifically discloses a process for the synthesis of carboxylated nitrile rubber latex which comprises the steps of (1) initiating the terpolymerization of 1,3-butadiene, acrylonitrile and methacrylic acid in an aqueous polymerization medium by the addition of potassium persulfate and a potassium persulfate co-initiator, wherein the terpolymerization is initiated in a reactor that is at least 60 percent full, (2) allowing the terpolymerization to proceed at a temperature which is within the range of about 25°C to about 80°C until a solids content of at least about 20 percent is attained to produce a seed polymer latex, (3) adding additional 1,3-butadiene, acrylonitrile and potassium persulfate to the seed polymer latex over a period of at least about 1 hour to produce a second polymerization medium and (4) allowing the polymerization to continue in the second polymerization medium for at least 0.5 hour to produce
Patent CA-2272936-A1 (CA)
Title: Method and apparatus for labelling containers with air-blow supported label transfer
Inventor: HINTON GAYLEN ROY
IPC: B65C9/28
Filed: 1998-01-29
Abstract: A method and apparatus for labelling containers allows labelling of containers by wrap around labelling without applying an adhesive on the leading edge of the label. Labels are held on a label drum and moved into a label applying position while containers are fed into the label applying position. Air is blown from a first position on the label drum onto the leading edge of the label at an angle to the label drum surface and in a direction backward along the label from the leading edge to force the leading edge of the label against the container, while also minimizing the laminar flow of air under the label.  After the leading edge of the label has engaged the container, air is blown from a second position on the label drum spaced from the first position onto the label and container at an angle to the label drum surface to maintain a laminar flow of air over the label and maintain the label tight against the container during container rotation. The leading edge is maintained on the container by wet adhesion or by air which is blown onto the label and container from first and second angled positions on the side opposite the label drum. Air can also be blown from a third position on the label drum spaced from the first and second positions onto the leading edge of the label after the container has rotated almost 360 degrees to maintain the label tight against the container during the final part of the wrapping process.

Title: Well completion system employing multiple fluid flow paths
Inventor: RIVAS OLEGARIO S
IPC: E21B43/38
Filed: 1999-07-13
Abstract: A technique is disclosed for completion of a well, such as an oil and gas production well. A packer is positioned in the well to divide the well into upper and lower zones. The packer has multiple passageways between the upper and lower zones. A pumping system is positioned in the lower zone for displacing wellbore fluids flowing from a production formation. The pumping system may include a liquid/gas separator, and express gas-phase components through one of the passageways and liquid-phase components through another. A conduit conveys the gas-phase components to a desired location. The liquid-phase components are conveyed to a collection location in the annular region surrounding the conduit. The conduit may be used for positioning a chemical injection line within the well, or for receiving a parameter sensing unit. The chemical injection and parameter sensing may be performed independently of gas production, and without interruption of either gas or liquid production.

Title: Punctum plug
Inventor: WEBB NICHOLAS J
IPC: A61B17/12
Filed: 1998-03-27
Abstract: A punctum plug (100) includes a proximal head (102), a distal body (106), and a thin walled flexible shaft (104) between the head (102) and the body (106). The thin wall of the shaft (104) of the plug (100) is preferably provided with accordion-like folds (114, 116, 118), thereby permitting the length of the shaft to vary depending upon the degree to which the accordion-like folds are folded or unfolded. In addition, the accordion-like folds permit the thin wall of the shaft to easily bend, permitting the head and body of the plug to lie along different axes. As a result, the plug is shaped to accommodate both relatively long and short vertical puncta, and the body of the plug may be angled relative to the head to accommodate a variety of anatomical structures. According to another aspect of the invention, the body of the plug may be provided with a thread which rotationally guides the plug into the small punctual opening.
