Patent CA-2538239-A1 (CA)
Inventor: SCATTERGOOD JOHN R
IPC: B22F9/10
Filed: 2004-09-08
Abstract: This disclosure relates to a novel process for atomizing a liquid material or a mixture of liquid materials. More specifically, this disclosure advances the art by utilizing the inertial forces created in an elevated acceleration environment to further miniaturize and enhance the characteristics of particles resulting from atomization. The key to this disclosure is to subject a melt material to an elevated acceleration and pass a fluid over the surface of the melt. The purpose of the elevated acceleration is to elevate the relative importance of gravitational forces in the melt thus miniaturizing any gravity influenced disturbance.

Patent CA-2541740-A1 (CA)
Inventor: COPELAND RICHARD L
IPC: H01F13/00
Filed: 1997-09-12
Abstract: A two-dimensional array of magnetomechanical markers (20) is adhered to a continuous web (62). A magnetizer element (70) is scanned (74) across the web (62) to magnetize the bias elements in a group of markers (20) with a first polarity, thereby activating the group of markers. The web (62) is then advanced (68) and the magnetizer (70) is scanned across the web in an opposite direction (76) to the previous scan to magnetize the bias elements of a second group of the markers (20) with a second polarity, thereby activating the second group of markers. The web (62) is slit in a longitudinal direction to produce web-strips each carrying a column of the activated markers. The web-strips are rolled to form marker roll assemblies each having about half the bias elements magnetized with a first polarity and the remaining bias elements magnetized with an opposite polarity. The roll of activated markers forms no more than a minimal "leakage" magnetic field.

Abstract: A mattress core having a plurality of holes therein features edge reinforcement members inserted into holes adjacent to the perimeter of the mattress core. Each edge member is made of a foam material having a greater firmness than the foam material of the mattress core body surrounding it in order to prevent sagging of the mattress edges due to exposure to repeated sitting. The edge members can be inserted about the entire perimeter of the core, or along any combination of edge portions, as increased firmness may not be desirable in all areas, for example at the head end of the mattress where sitting is less likely to occur. In one embodiment, a second row of edge members is provided inward of the row directly adjacent the perimeter. This second row is more compressible, or less firm, than the first, providing an incremental increase in firmness towards the edge.
