Patent CA-2213732-A1 (CA)
Title: Time-temperature integrating indicator device
Inventor: ARENS ROBERT P
IPC: G01N3/04
Filed: 1996-03-07
Abstract: A selectively activated time-temperature integrating device for providing a visually observable indication of cumulative thermal exposure, in which a viscoelastic material migrates into a diffusely light-reflective porous matrix at a rate which varies with temperature to progressively change the light transmissivity of the porous matrix and thereby provide the visually observable indication. The viscoelastic material can comprise a pressure sensitive adhesive. The visually observable indication can comprise latent indicia which initially are not visible and become visible, obscurable indicia which initially are visible and become obscured, or a combination of both. Various actuating means for selectively switching the indicator from an unactivated state to an activated state are described. Also disclosed are a method for providing a visually observable indication of cumulative thermal exposure and a method for providing a time and temperature integrating device for providing a visually observable indication of cumulative thermal exposure of an object.

Abstract: The invention relates to a cover for preventing the contents of a can from entering a top sealing groove such as that which is present in paint cans. The cover is in the form of a thin-walled body of substantially consistent thickness which may be thermoformed from a thin sheet of plastic material, such as recycled PET. The body includes an annular portion which in cross-section has a top portion for spanning the groove and downwardly depending inner and outer flange portions which straddle the groove forming parts of the can. The outer flange portion depends below an outer bead at the top outer edge of the can and defines a plurality of circumferentially spaced, inwardly directed impressions for projecting inwardly beneath the outer bead of the can. An outwardly projecting annular web is formed at the bottom of outer flange, and a lower downwardly depending flange is joined to the annular web and has an inner surface of substantially the same diameter as the outer surface of the outer flange portion depending from the top portion to allow nesting of the cover within the lower part of a like cover placed thereover.

Patent CA-2231044-A1 (CA)
Inventor: ULSETH CHRIS
IPC: B65G53/42
Filed: 1998-05-06
Abstract: The application relates to a method of transporting granular substances over long or short distances by means of suspending the granules within a moving mass of low pressure air, which is itself restrained in a length of pipe. The moving, low pressure air is generated by one or more lobe blowers which may be driven by electric or other motive power units. The air is introduced into the system at a shallow angle, enabling the air stream to smoothly flow through the accelerator portion with minimum turbulence and loss of energy. The accelerator cone and venturi are responsible for the ultimate speed of the product flow, which may range up to 11,000 feet per minute; the actual velocity will vary with the type of material handled, its density and grain size. Product is introduced into the air stream from the rear in most cases and brought up to its initiation speed by a high speed auger. In reverse action units, the auger is exposed at its entry end, to the product source and conveyed to a curved portion of the pipe before being caught up into the high velocity air stream. The Pneumatic Units are viable in a range of capacities, from 2" diameter up to 12"     Distances over which product may be conveyed again vary with the product characteristics, but field measurements up to 600 feet within the pipe and an additional free air delivery of up to 300 feet have been recorded. The inclusion of additional blowers and accelerators at intervals enable the movement of product over very long distances, as for example in a cross country pipeline. The technical field covered by this abstract and application is "the movement of materials within a cushion of air by diffusing in a low pressure air stream"

Title: Blade protector for hockey stick
Inventor: PICARD JEAN-MARC
IPC: A63B60/56
Filed: 1998-06-09
Abstract: A blade protector for use on the blade of a hockey stick comprises a pair of substantially vertical and spaced apart side walls defining a cavity therebetween for receiving the blade of the hockey stick, the two side walls being integrally connected at their lower ends by a substantially horizontal web which is designed to elevate the blade of ground to prevent the blade from becoming damaged when the hockey stick is used on ground surfaces, such as asphalt and cement. Typically, two blade protectors are provided on the hockey blade, that is at the front and at the heel of the blade. The web of the blade protector defines a recess dimensioned to accommodate hockey tape which is used to secure the blade protector to the blade by surrounding the blade protector and the hockey blade. As the tape is lodged in the recess of the web, ridges defined on the web outwardly of the recess prevent the tape from contacting the ground surface. The blade protector may be curved to follow a curve of the blade. An upper surface of the web located between the side walls of the blade protector may be concave such as to follow the convex lower edge of the hockey blade.
