Title: Papermaking machine with papermaking belt
Inventor: AMPULSKI ROBERT S
IPC: D21F1/10
Filed: 2001-08-31
Abstract: A papermaking belt for use in making hard grades of paper such as printing kraft, newsprint, linerboard, fine or writing grades of paper. The papermaking belt may be used in conjunction with a single-wire draw or twin-wire draw of a papermaking machine. The papermaking belt comprises a woven reinforcing element and a patterned framework. The framework defines either or both faces of the papermaking belt. The pattern of the framework is independent of the weave of the reinforcing element. This arrangement decouples the amount and pattern of the paper-contacting surfaces of the belt from the weave and/or permeability of the belt. Further, this arrangement allows for increased and more uniform contact area of the paper web against a drying cylinder. Additionally, this belt provides an increased wear surface for improved belt life.

Patent CA-2628834-A1 (CA)
Inventor: GUILLET JAMES E
IPC: B22F1/054
Filed: 2001-05-28
Abstract: There are provided internally cross-linked, stable polymeric materials, in the form of substantially spherical particles, each particle consisting essentially of a single macromolecule. They have the unusual property of being soluble or dispersible in a liquid medium without significantly increasing the viscosity of the medium, rendering them potentially useful in imaging applications such as ink jet printers. They can be prepared by dissolving polymeric material in a solvent system to form a solution of the polymeric material at a concentration therein of less than the critical concentration for the polymer, causing the polymeric material to contract into an approximately spheroidal conformation in solution, cross-linking the polymeric material in solution in said spheroidal conformation so assumed, and recovering stable, cross-linked approximately spheroidal polymeric particles from the solution.

Title: Pin bone removal apparatus
Inventor: SHIPMAN GREGORY KENNETH
IPC: A22C25/16
Filed: 2006-11-16
Abstract: A pin bone removal device that provides a plurality of fixed members arranged substantially in side-by-side orientation. The invention also comprises a plurality of moveable members also substantially arranged in a side-by-side orientation. In one aspect, the fixed members and moveable members collectively form a stack of members in which a moveable member is positioned adjacent each fixed member. In this aspect, a linear drive is operatively connected to each of the moveable members and is configured to cause oscillating movement of each moveable member to cause the moveable members to contact the adjacent fixed member. This movement causes pinch points to be created and released between the fixed and moveable members. As the fillet of fish is moved along the stack of members, the pin bones are caught at each pinch point and then released.
