Patent CA-2149494-A1 (CA)
Inventor: GILBERT SCOTT ROBERT
IPC: B65D30/28
Filed: 1995-05-16
Abstract: A flat trapezoidal container provides a generally frustoconical bag with a single cavity when at least partially filled with a pulverulent material such as soil which may have a live plant growing therein, or comestible goods such as popcornand other snacks which rely heavily upon spur-of-the-moment purchases by a cus-tomer who must first be visually attracted to the goods, thereafter be visually convinced of their freshness, and have the opportunity to smell and/or touch thegoods prior to purchasing them. The container may also be specifically dimensioned to snugly sheath a flower pot so as to leave therebeneath, a surplus of film in an empty transition zone which is concealable under the flower pot. The container is made from two flat panels of heat-sealable film, each shaped as a trapezium; or from a single web folded double. The lower portion of the container is ornamentally imprinted along a border extending beneath a generally lateral line above the longi-tudinal axis of the web, to identify the contents and simulate them in their optimum condition to enhance their marketability; and, with a marker in the upper portion, quantifies the volume of the goods contained, or provides instructions for their use. When the cavity is distended by being partially filled, the entire container, except for a transition zone, presents a smoothly arcuate surface of the frustum of a cone. The lower exterior portion is continuously printed with ornamental images of thecontents, or images evocative thereof, without an interruption in the printing, such as is present as an elongated blank rectangle in prior art bags. The transparentupper portion is free from an elongated portion of the printed image near the edges, as in prior art bags. A method is disclosed for forming the printed container which method requires discarding the material for one bag for each bag made by thermally sealing the equally, but oppositely angulated sides of the trapeziums, and the shorter of the remaining parallel sides.

Title: Microballoon catheter
Inventor: RICHLING BERND
IPC: A61F2/958
Filed: 1995-01-26
Abstract: This invention is a microballoon (108) tipped catheter (100). The catheter has a shaft (104) which is of varying flexibility with the most flexible portion towards the distal tip. The balloon is of an elastic material. The catheter shaft has a main lumen (114) extending from the proximal end to the distal end so to allow the use of a guidewire (101) in placing the catheter's distal tip in remote regions. The catheter shaft has a wall that desirably is of multilayered construction. The wall preferably includes an independent lumen (110) which may be formed from a small diameter tubing that is placed between layers of the wall, for the inflation and deflation of the microballoon. The inflation lumen proceeds from the proximal end of the catheter and terminates near the distal end of the catheter but within the microballoon.

Abstract: Novel maleimide copolymers have at least two monomeric units, a maleimide unit and a vinyl unit having a pendant group, the pendant group having two to twenty-one carbon atoms, at least one nitrogen atom and at least one oxygen atom. The copolymer has an average molecular weight between about 1,000 and about 6,000,000. Preferred maleimide copolymers include acrylamide/maleimide copolymers, N-vinyl amide/maleimide copolymers, vinyl lactam/maleimide copolymers, alkenyl cyclic imino ether/maleimide copolymers, and acryloylamide/maleimide copolymers. The substantially water soluble maleimide copolymers are useful for inhibiting the formation of clathrate hydrates in a fluid having hydrate-forming constituents by reducing the rate of nucleation, growth, and/or agglomeration of gas hydrate crystals in a petroleum fluid stream, thereby inhibiting the formation of a hydrate blockage in the pipe conveying the petroleum fluid stream. The inhibitor can be used conveniently at low concentrations, for example in the range of from about 0.01% to about 5% by weight of the water present in the oil or gas stream, to effectively treat a petroleum fluid having a water phase.

Abstract: A method for automatically providing weather advisories for an airport to pilots comprises monitoring weather conditions at the airport and then generating weather advisories in response to these weather conditions. The broadcast traffic on a common traffic advisory channel is also simultaneously monitored and then menus providing for selectable weather advisories and radio check options are broadcast to the pilots. The weather advisories or radio check can then be selected by the pilot by clicks of their transmit button. The time spacing between the menus is adaptively changed in response to traffic on the common traffic advisory frequency. Also, the length of the weather advisories is also changed in response to this traffic. The radio check option is provided automatically by first confirming selection of the radio check option and then allowing the broadcaster to broadcast a short message which is recorded by the system and then rebroadcast.
