Title: Selectively closeable plastic film bag
Inventor: PAPPAS GEORGE
IPC: B65D33/20
Filed: 2000-01-31
Abstract: A selectively closeable plastic film bag is formed with front and rear plastic film panels. The bag includes a bottom and side edges and each of the front and rear panels include a top edge whereat an opening is provided into the bag cavity. An adhesive strip is provided on the inside surface of the front or rear panels extending longitudinally thereacross between the bag side edges. The adhesive strip is placed in a pattern extending at an angle upwardly from each of the side edges to a generally linear portion therebetween. A release liner is provided between the front and rear panels and is located partially over or above the adhesive strip at the side edges and below the linear adhesive strip portion. The adhesive strip portion covered by the release liner is prevented from coming in contact with the other bag panel thereby retaining the bag open. The release liner is detachably attachable to the adhesive strip. For closing the bag, the release liner is pulled out from between the panels causing the adhesive strip to come in contact therewith. The adhesive strip extends uninterrupted from side edge to side edge thereby making the closure leakproof. Pocket panels are attached to the bag thereby forming pockets for selectively receiving items therein. The front and rear panels are provided with weakened material lines extending between the side edges for easily ripping and gaining access to the bag cavity. To prevent fusing of the release liner to the front and rear panels, both the release liner and front and rear panels are cut away at the bag side edges above the adhesive. The release liner extends above the front and rear panels top edges or into notched areas at the bag side edges whereat it may easily be gripped.
Patent CA-2298865-A1 (CA)
Inventor: DEZIEL ANDRE
IPC: B25C1/04
Filed: 2000-02-15
Abstract: The nailing tool has a hollow main body including a valve slidable therein. The main body includes a compressed air reservoir, the compressed air keeping the valve closed in a resting position. An anvil is provided at the upper end of the tool, with an empty annular chamber at atmospheric pressure being located under the anvil and over a ring integrally attached to the valve. Thus, if a hammer blow is dealt on the anvil, the latter loosely slides inside the main body, without reaching the ring, with the valve remaining closed and no fastener being expelled from the tool. Upon a trigger being activated on the tool handle, compressed air fills the annular chamber between the anvil and the ring. In this condition, upon a hammer blow being dealt on the anvil, the impact of the blow is transmitted by the compressed air to the underlying ring, consequently opening the valve. The opened valve allows compressed air to flow into an underlying piston drive chamber, where a piston is driven by the sudden compressed air inflow to drive a fastener out of the tool. Air exhaust channels allow the piston and the valve to return in their initial resting positions after a nail has been expelled from the tool.

Title: Method of enhanced sterilization with improved material compatibility
Inventor: MERHAZION ABRAHAM
IPC: A61L2/20
Filed: 2000-03-29
Abstract: A method of enhanced sterilization with improved material compatibility. The following enhancements have been made. First, repeated venting , evacuation, and plasma treatments can be performed in the pre-plasma stage. Second, a lower power level can be used in the post-plasma stage than in the pre-plasma stage. Third, after the post-plasma-stage, the chamber can be held at atmospheric pressure or sub-atmospheric pressure for a period of time after venting, before re-evacuating the chamber, rather than evacuating after the chamber is vented to atmospheric pressure or sub-atmospheric pressure. Any of the three enhancements may be used separately, and it is not necessary to practice all three enhancements to obtain at least some of the benefits of enhanced sterilization with improved material compatibility.

Patent CA-2305441-A1 (CA)
Title: Methods of using ice-controlling molecules
Inventor: FAHY GREGORY M
IPC: C07K14/00
Filed: 1998-10-02
Abstract: A dispersal pattern of hydrogen bonding sites on an ice surface is used as a template in a process for the design, selection and manufacture of synthetic ice interface dopants. Ice interface dopants are generally molecules which bind to a surface of an ice crystal and inhibit subsequent gain or loss of water molecules. The ice interface dopants can thus inhibit ice crystal growth, recrystallization, and sublimation. Ice interface dopants can also inhibit heterogeneous nucleating agents, and thus postpone or prevent ice nucleation. On the other hand, very strong IIDs may be used as well to beneficially induce ice nucleation. Exemplary dopant structures are provided that achieve near-perfect ice-bonding efficiency while being thoroughly adaptable to a wide variety of specialized ice-bonding applications. Orbital steering provides for steering lone pair orbitals of ice bonding atoms in the interface dopant to result in an optimal angular alignment with the complementary binding sites on ice.
Patent CA-2307230-A1 (CA)
Inventor: HEBBAR MOHAN A
IPC: F01D5/28
Filed: 1998-10-27
Abstract: Large gas turbine blades (10) made from separate cast segments (12, 14. 16, 18) of superalloys are disclosed. The turbine blade is designed such that bond lines between adjacent segments are placed in low stress regions of the blade.  The cast superalloy segments of the blades are aligned and fitted together with specified tolerances. The turbine blade segments are then joined by transient liquid phase bonding, followed by a controlled heat treatment which produces the desired microstructure in the bond region. The method allows for the production of large, high quality turbine blades (10) by joining small, high quality cast superalloy sections (12, 14, 16, 18), in comparison with prior attempts to cast large turbine blades as single pieces which have produced very low yields and high individual component costs.
