Patent CA-2308682-C (CA)
Title: Expanded film base reinforcement for papermaker's belts
Inventor: ROMANSKI ERIC R
IPC: D21F3/00
Filed: 2000-05-17
Granted: 2006-11-28
Abstract: A resin-coated endless belt for a long nip press has a base which is a polymeric film structure in the form of an endless loop with an inner surface, an outer surface, a transverse direction and a longitudinal direction. The polymeric film structure has a plurality of perforations which may be aligned in one or both of these directions. The polymeric film structure is stretched in the presence of heat to orient the molecular chains in the unperforated intervals between the perforations to provide the structure with tenacity and resistance to further stretching. At least the inner surface of the base (polymeric film structure) is coated with a polymeric resin material, such as polyurethane. The polymeric resin material coats the base and upon curing, forms a mechanical interlock therewith by virtue of the perforations, and renders it impermeable to oil and water. In addition to being useful for a long nip press, the belt may also be used in other papermaking applications, for example, as a calender belt on a calender of the shoe type or on a calender having two or more rolls, or as a transfer belt.

IPC: B29C45/78
Filed: 1999-06-09
Granted: 2008-08-12
Abstract: The invention relates to a method of cooling machines. Typically, the method of cooling is useful in the cooling of dies used in the moulding of plastics or metals. The method relies upon taking advantage of t he latent heat of vaporisation of a cooling liquid. A liquid is maintained in a closed chamber in a die such that the liquid is in contact with the surfaces to be cooled and a space above the liquid surface is available. The pressure in the space is adjusted, typically by vacuum equipment, such that the boiling point of the liquid is adjusted to a level which enables the principle cooling process to involve latent heat.</S DOAB>

Title: Aluminum alloys having improved cast surface quality
Inventor: DEYOUNG DAVID H
IPC: C22C21/00
Filed: 2001-09-21
Granted: 2012-11-27
Abstract: Aluminum alloy compositions are disclosed, which include small amounts of calcium that result in improved surface properties of the cast aluminum. The calcium, and up to 0.25% grain refiners, are added along with alkaline earth metals, transition metals and/or rare earth metals to the aluminum alloy as a melt. The addition results in improved appearance, substantially reduced surface imperfections and reduced surface oxidation in cast ingot aluminum and aluminum alloys. The addition of small amounts of these additives, surprisingly were found to substantially eliminate vertical folds, pits and ingot cracking in more than one ingot casting technique. The additions also improved the appearance of the ingots, including reflectance. As a result, the ingots could be reduced or worked essentially right out of the casting without first conditioning the surface by, for example, scalping. Also disclosed is a method of improving the surface properties and preventing surface imperfections and cracking of cast aluminum alloys. The method includes the steps of adding calcium to a molten aluminum alloy that is essentially free of Be casting the aluminum alloy using any commonly used technique.
