Title: Belt press for continuous manufacture of wood-product members
Inventor: GERHARDT KLAUS
IPC: B27N3/24
Filed: 1995-10-27
Abstract: A continuous press for a compressible wood-product strand has a row of longitudinally spaced open frames, upper and lower heated press plates extending in a longitudinal direction through and supported by the frames, and respective upper and lower sheet-steel belts having respective lower and upper stretches extending longitudinally parallel to each other through the row of frames between the plates from the upstream to the downstream ends and defining a longitudinally extending passage having an upstream end, a downstream end, and a center between the ends.  A drive advances the stretches longitudinally downstream and thereby draws in the wood-product strand longitudinally and compresses it transversely.  Two sets of transversely displaceable downstream pressing elements transversely oppositely engageable between the center and the downstream end with the strand between the belts are displaceable longitudinally downstream synchronously with the strand.  These pressing elements are urged transversely inward against the strand by actuators provided between the frames.

Abstract: A structural member (10) formed from a billet, each member (10) comprising a plurality of corrugated paperboard sheets (12) bonded together with an adhesive (14) and disposed between a core fibre layer (16, 18), each core fibre layer (16, 18) comprising at least one ply of a fibreboard sheet (19), a pair of caps (20, 22) of a solid fibreboard sheet bonded to respective side faces of the paperboard sheet (12) and to the respective edges (23) of the core fibre layers (16, 18). A method of manufacture is disclosed in which the billet is built up of corrugated paperboard sheets (12). The billet is then ripped into planks for use as a plank, board, or cleat, particularly as components for corrugated paperboard containers. A pallet made of planks and a pallet made of planar sheets cut from the billet are disclosed.
Patent CA-2163586-A1 (CA)
Inventor: EADY ROBERT FREDERICK
IPC: B65G53/08
Filed: 1995-11-23
Abstract: A bulk material transportation system accelerates the bulk material to a selected velocity and mixes it with an airflow. When moving through the delivery pipe, the airflow forms a laminar airflow with the slower layer of the airflow occurring adjacent the inner surface of the pipe and the higher velocity layers of the airflow occurring toward the center of the pipe.  As the bulk material moves through the pipe, its velocity is increased by the higher velocity layers and is inhibited from making frictional contact with the inner surface of the pipe by the lower speed layers. The bulk material thus flows through the delivery pipe with little contact with the interior of the delivery pipe.

Title: Braking mechanism for in-line skates
Inventor: DAOUST BERNARD
IPC: A63C17/14
Filed: 1995-06-29
Abstract: The braking mechanism has two generally L-shaped levers (8), one on each side of the skate. Each lever has two arms, namely an upwardly projecting arm (10) and a rearwardly projecting arm (12), pivotally connected to the chassis of the skate where the arms intersect (14), such that each upwardly projecting arm extends upwardly in general alignment with the skater's leg, and that each rearwardly projecting arm extends rearwardly from the chassis, the rearward distal ends having a brake pad (16) secured beneath them. The upper distal ends may be connected to a pivotable boot cuff (5), but preferably instead have a generally C-shaped cup (18) extending laterally between them, positionable behind the skater's calf or against a liner (4) of the boot. Rearward rotation of the skater's calf relative to the boot produces rearward movement of the upper distal ends, thereby moving the brake pad downwardly.

Inventor: BOUCHARD PETER A
IPC: G03F7/34
Filed: 1995-06-02
Abstract: Methods and apparatus for peeling a laminate containing image media wherein the leading edge portion of the laminate is struck by beater blades to initially separate the leading edge portion of one layer from the laminate.  The separated leading edge portion is then transported into a nip defined by a peel surface (70) and a lower peel roll (68) after which the leading edge portion is bent about the peel surface (70) by a folder (91) driven by a linkage mechanism. While the leading edge portion of the laminate is bent, one layer is held by a vacuum device (84) while the remainder of the laminate returns to its path of travel under its own resiliency. The separated layer is then peeled from the laminate by take-away rolls while guided by the peel surface. The remainder of the laminate is guided by a deflector roll to move along the path at a predetermined angle while the layer is being peeled. In one method, the layer is peeled at an angle to the longitudinal direction of the laminate. This is effected by orienting the peel surface and the lower peel roll (68) with their axes extending at an angle to the path of travel of the laminate. Further, a method includes having the layer peeled at an angle other than the screen angle of the imaged and non-imaged portions of the laminate. A small diameter peel surface (70) is used for effective peeling.
