Patent CA-2049221-C (CA)
Title: Double hoist drive using load coupled hold and close variable frequency motors
Inventor: JAMES MICHAEL
IPC: B66C3/12
Filed: 1991-08-14
Granted: 1996-01-16
Abstract: A hoist drive for a double hoist carrying member having a hold hoist drum, a hold rope connected to the hold hoist drum and from which the carrying member is suspended, and a hold motor for rotating the hold hoist drum to raise and lower the carrying member.  The hoist drive further includes a close hoist drum, a close rope connected to the close hoist drum and from which the carrying member is suspended, and a close motor for rotating the close hoist drum to raise and lower the carrying member.  During raising of the carrying member, the hold and close motors are each supplied with a.c. power at different preselected frequencies.  The hold and close motors each operate along a first pair of intersecting frequency to torque curves during a raising operation in which the hold motor curve is steeper than the close motor curve.  During a lowering operation the hold and close motors operate along a second pair of intersecting frequency to torque curves in which the hold motor curve is also steeper than the close motor curve.  Due to the intersection and relative slopes of the first pair and the second pair of curves, the speed of the hold motor follows the speed of the close motor during both raising and lowering operation and the motors operate at the intersection points of the pairs of curves and share the load during both raising and lowering operation.

Title: Polyolefin resin and method for the preparation thereof
Inventor: NAKACHO KENJI
IPC: C08F10/00
Filed: 1993-02-16
Granted: 1997-06-03
Abstract: A novel method for the preparation of a polyolefin such as an ethylene-based copolymeric resin is proposed.  The polymeric resin obtained by the method has a very high average molecular weight to ensure excellent mechanical properties of the shaped articles therefrom but still is capable of exhibiting good molding workability by virtue of the relatively low melting point and low degree of crystallinity.  The method comprises contacting an olefin monomer or monomers with a unique catalyst system compris-ing, for example,  (a) a titanium compound such as titanium tetraalkoxides,  (b) an aluminoxane compound and (c) an organic aluminum compound such as trialkylaluminums and/or (d) an organic compound having a .pi. electron in a molecule such as toluene, in a specified molar proportion.  Prefer-ably, these catalytic ingredients are contacted with each other prior to their contacting with the monomer or monomers to be polymerized so that the catalytic activity of the catalyst system can be further enhanced.

Patent CA-2106024-C (CA)
Inventor: DEDIO EDWARD LEWIS
IPC: G03C5/58
Filed: 1993-09-13
Granted: 1997-01-07
Abstract: A photothermographic element comprising a photosensitive silver halide, an organic silver salt and a reducing agent in concentrations such that imagewise exposure to actinic radiation generates from the silver halide a catalyst which accelerates an image-forming reaction between the organic silver salt and the reducing agent is processed by a method comprising the steps of (1) imagewise-exposing the element to actinic radiation to form a latent image therein, (2) subjecting the imagewise-exposed element to a first heating step at a temperature and for a time sufficient to intensify the latent image but insufficient to produce a visible image, and thereafter (3) subjecting the element to a second heating step at a temperature and for a time sufficient to produce a visible image.  This method of "thermal latensification" serves to greatly reduce the significant speed losses that were heretofore encountered with photothermographic elements when considerable time was allowed to lapse between exposure to actinic radiation and generation of the visible image by heating.
