Title: Adsorbent filtration system for treating used cooking oil or fat in frying operations
Inventor: ABRAMS CHRIS
IPC: A47J37/12
Filed: 2000-07-12
Abstract: A process for treating used cooking oil or fat by passing the used cooking o il or fat from a used cooking oil or fat source to a holding vessel, and contacting the used cooking oil or fat with a predetermined amount of purifying material upon accumulation of a first predetermined amount of the oil or fat in the holding vessel. The used cooking oil or fat and the purifying material then are passed from the holding vessel to a filter apparatus upon accumulation of a second predetermined amount of the oil or f at in the holding vessel. The second predetermined amount of oil or fat is greater than the first predetermined amount. Upon passing of the used cookin g oil or fat and the purifying material from the holding vessel to the filter apparatus, the purifying material becomes entrained in the filter apparatus.  The used cooking oil or fat then is passed from the filter apparatus for the  source. After the oil or fat is treated, residual oil or fat and the used purifying material may be removed from the filter apparatus by blowing gas through the filter apparatus.

Patent CA-2379654-A1 (CA)
Inventor: GONS JOHAN
IPC: C08J9/04
Filed: 2000-07-12
Abstract: La présente invention concerne un procédé de formage d'un article comprenant une micromousse à alvéoles fermées issue de thermoplastique. Dans ce procédé au moins un thermoplastique fondu comprenant un agent d'expansion est soumis sous pression à une opération de formage et, après que la pression a été au moins partiellement levée, il est refroidi. Ce procédé se caractérise par le fait que la quantité d'agent d'expansion est sensiblement identique à la quantité correspondant à celle du gaz libéré par cet agent d'expansion qui est confiné dans la structure condensée et fermée des alvéoles de la mousse, lesquelles possèdent un diamètre alvéolaire spécifique, de façon sensiblement uniforme dans cette mousse, à la pression régnant au cours du refroidissement. Si en guise d'agent physique d'expansion on utilise l'azote et le PP en guise de plastique, la concentration se monte environ à 0,12 wt %, en masse du thermoplastique, alors que cette valeur est d'environ 0,19 wt % si l'on utilise du dioxyde de carbone en guise d'agent d'expansion. Ce procédé est opportunément mis en oeuvre sous forme de procédé d'extrusion, éventuellement sous forme de procédé de coextrusion. L'utilisation du talc comme agent nucléant est bénéfique, et dans le procédé de cette invention la concentration de talc s'avère être un facteur déterminant du diamètre de l'alvéole.

Patent CA-2392960-A1 (CA)
Inventor: BRENGER ANDREAS
IPC: C09J175/04
Filed: 2000-11-25
Abstract: Polyurethane compositions are produced in a two-step process, wherein, in a first step, a diol component with a molecular weight of less than 2000 is reacted with a monomeric diisocyanate with a molecular weight of less than 500 and the unreacted monomeric diisocyanate is removed from this reaction product and then, in a second step, the resulting high molecular-weight diisocyanate is reacted with a polyol so that a reactive prepolymer with isocyanate terminal groups is formed.   An addition of migratory polyisocyanates having a substantially lower vapour pressure than diphenylmethane diisocyanate improves the adhesion properties of the polyurethane compositions according to the invention.  These reactive polyurethane compositions are suitable for use as binders for reactive one- or two-pack adhesives/  sealants, which can optionally be solvent-based. With a suitable choice of polyols, these compositions are also suitable for the production of reactive hot melt adhesives. A substantial advantage of these compositions compared with known polyurethane compositions is the drastically reduced proportion of monomeric diisocyanates with a molecular weight of less than 500.
