Title: Polymeric alloys
Inventor: KYU THEIN
IPC: C08L67/00
Filed: 1990-04-11
Abstract: Abstract of the Invention Two-component polymeric composition having two interconnected solid phases, and exhibiting spinodal decomposition morphology at the domain boundaries are shown, as are methods for forming the same.  The compositions are prepared from two different polymers, one of which possesses ductility in that it shows substantial yield behavior under tensile stressing, the other being brittle, exhibiting no such behavior; thermoplastic polymers, in conjunction with thermotropic liquid crystalline materials, exemplify such systems.  The desired morphology is created by preparing the two component compositions in a single solid phase below the lower critical solution temperature of the compositions, and thereafter heating the compositions above such temperature to form a two-phase system.  After a predetermined period of time at the upper temperature, during which spinodal decomposition spontaneously occurs, temperature of the compositions below the lower of its two glass transition temperatures.

Title: Shuttle drive
Inventor: SHAW DONALD E
IPC: B66F9/075
Filed: 1990-09-21
Abstract: Abstract of the Disclosure A shuttle drive is disclosed for a storage and retrieval machine having a shuttle mounted on a carriage which is vertically movable on a mast for carrying objects to and from overhead storage spaces.  The mast is mounted on a base and the mast and base together travelable to designated locations.

Patent CA-2025911-A1 (CA)
IPC: B66F9/07
Filed: 1990-09-21
Abstract: A mast connecting structure is disclosed in which the mast includes a lower end having upper plate means connected to the lower end of a mast, and lower plate means spaced from the upper plate means and connected to a base on which the mast is to be mounted.  Tensioned connecting means connect the upper plate means and lower plate means together to thereby mount the mast on the base. The connecting means may comprise bolts having threaded ends and nuts threaded on the bolts.  The bolts have an elongated length sufficient to span the thickness of the upper and lower plate means through which the volts pass plus the distance of the space between the upper and lower plate means.  The long bolt length increases the volume of the bolt body which results in an increased stress distribution and thereby an increased ability to withstand stress due to impact loading of the connecting structure.  The mast end and mast base are preferably held apart at a spaced distance by support means such as spacer tubes positioned between the upper and lower plate means and coaxially with the connecting bolts.

Patent CA-2029134-A1 (CA)
Inventor: GRETHER PAUL
IPC: C03C27/06
Filed: 1990-11-01
Abstract: The glazing element is provided with at least one tensioned insulation form (2) between two panes (1). Spring elements (3) secured to a tension profile (4) serve to place the film under tension. The spring elements are distributed over the entire film periphery. They are also elastically bendable in all directions transverse to their elongation, and are secured with their longitudinal direction essentially perpendicular to the film plane with one end at the film and the other end secured to the tension profile In this manner, the spring elements can elastically follow relative shape alterations of the film with respect to the tension profile by bending transversely to their longitudinal direction. In this novel construction, tension forces are distributed in all directions in the insulation film. No friction forces need to be overcome in order to tension the film. The entire tension taken up by the film support is so small that it is possible simply to adhere the tension profile inwardly to the panes. Simple helical coils can be used as the spring elements
