Title: Nonionically stabilized polyester urethane resins for water-borne coating compositions
Inventor: BALATAN SERGIO E
IPC: C08G18/10
Filed: 1990-07-17
Abstract: Laterally stabilized, water-miscible polyester polyurethane resins, useful as principal binder resins and as pigment grind resins in water-borne coating systems are the reaction product of one or more polyols, one or more polyisocyanates, and a polyester prepolymer formed by the reaction of a polyether alcohol, one or more polyols, and one or more polyfunctional carboxylic acids. The resins have a polyester polyurethane backbone with pendant polyether groups, attached to the polyester segments of the backbone, which serves to solubilize arid stabilize the resins in aqueous media. The resins have small dispersion particle size at the same or higher molecular weights than similar prior art resins, and produce better metal flake orientation when used as the principal resins in base coat formulations which contain aluminum and mica particulates for "metallic" effect coating finishes.
Patent CA-2023220-A1 (CA)

Filed: 1990-08-14
Abstract: In a spacer frame for use in separating panes of glass of an insulated glass panel, a cornerpiece has first and second arms joined by a flexible hinge to permit angular movement of said arms with respect to one another. The first and second arms each have a first portion that has a cross-sectional area substantially equal to the cross-sectional area of a spacer bar into which they are inserted, and a second portion that protrudes from the spacer bar that is of a cross section larger than said first portion to form a shoulder that is adjacent and abutting the end of the spacer bar. The shoulder is substantially continuous around its perimeter tosubstantially eliminate moisture paths from outside said spacer bar to the interior of the spacer bar. The folded corner presents an essentially solid mass that prevents moisture from entering the spacer bar. The cornerpiece also includes anangled projection that extends from a first end of the first arm and a slot formed in the first end of the second arm, the projection and slot cooperating with oneanother to form an interference fit that releasably holds the first and second arms in a desired angular relationship. A first surface of each of said first and second arms has a series of sawtooth-like serrations formed thereon that interferes with an interior surface of the spacer bar to aid in maintaining the arm in the spacer bar.

Title: Turret spicer for web rolls
Inventor: BUTLER RICHARD A JR
IPC: B65H19/16
Filed: 1990-10-02
Abstract: ABSTRACT OF THE DISCLOSURE      A turret splicer includes various novel features that enable it to reliably splice web from different rolls at any speed between (and including) zero and the line speed of a down-stream web consuming machine, such as a printing press. The turret splicer includes a large accumulator for supplying web while the splice is being made at less than line speed.  In addition, the splicer has translatable roll support carriages which enable each roll to be mounted independently onto the turret, and moved laterally within the turret.  The turret is rotatable by an improved drive arrangement that places the turret motor near the floor, and uses a mechanical linkage to communicate the output of the motor to journal shafts on which the turret is mounted.  Thus, the large, central turret shaft of conventional turret splicers has been eliminated. Acceleration of the rolls is achieved by conical drive elements which only contact the rolls along their sides, and do not contact the surface of the web.  The splicing mechanism includes an improved, cushioned pressure roll, and a pivotally mounted knife.  A computer is used to control roll loading, roll accelerating, web splicing and the other features and operations of the turret splicer.

Abstract: A hearth arrangement for a furnace which melts  refuses carried  on the hearth arrangement comprises a  plurality  of hearth  blocks arranged like a stair.  The hearth blocks  are inclined  stepwise  in a refuse carrying direction  and  each hearth  block  has  a width direction  perpendicular  to  the refuse carrying direction.  Each hearth block is divided into two block elements in the width direction of the hearth block and  the  two  block elements are joined  to  each  other  by springs which exerts a biasing force on the block elements in the  width  direction of the hearth block.   A  clearance  is formed  between each two adjacent hearth blocks  to  tolerate heat  expansion  of  the  hearth blocks.  Each  block  has  a protuberance  extending over a next hearth block  located  in the  ash carrying direction such that the ash does  not  flow into  the  clearance  between the hearth  blocks.   A  convex portion is formed on a contacting plane of one block  element and a concave portion is formed  in a contacting plane of the other block element such that the convex portion engages with the concave portion to ensure a tight engagement of two block elements.
