Title: Process for the recovery of crude terephthalic acid (cta)
Inventor: PIRAS LUCIANO
IPC: C07C51/42
Filed: 2000-11-30
Abstract: The present invention relates to a process for the preparation of crude terephthalic acid which comprises first introducing a slurry containing crystallized terephthalic acid with impurities in an aliphatic carboxylic acid mother liquor into a rotary filter comprising a case and a rotating drum, wherein the rotating drum is subjected to a uniform pressure differential over the entire drum, and the inside of the drum is at a pressure approximately equal to atmospheric pressure or greater, then filtering said slurry; and finally collecting at least some of the solid portion. Other aspects of the invention include continuously adding the original slurry to the rotary filter and washing the solid portion with additional aliphatic carboxylic acid, water or a combination of the two. The solid portion can then be transferred to a reslurry tank which is at the same pressure as the pressure at the point where the solid portion was collected. The present invention also relates to a process for the preparation of crude terephthalic acid which comprises first introducing a slurry containing crystallized terephthalic acid with impurities in an aliphatic carboxylic acid mother liquor into a rotary filter comprising a case and a rotating drum, wherein the rotating drum is subjected to a uniform pressure differential over the entire drum, then filtering said slurry, washing the solid portion with water; and finally collecting at least some of the solid portion. Other aspects of the invention include continuously adding the original slurry to the rotary filter and additional washing with the aliphatic carboxylic acid mother liquor. The inside of the drum can be less than, greater than or approximately equal to atmospheric pressure. The solid portion can then be transferred to a reslurry tank which is at the same pressure as the pressure at the point where the solid portion was collected.

Title: Method and reactivating solid catalysts used in alkylation reactions
Inventor: THOMPSON DAVID N
IPC: B01J38/56
Filed: 2001-06-13
Abstract: A method for reactivating a solid alkylation catalyst is provided which can be performed within a reactor that contains the alkylation catalyst or outside the reactor. Effective catalyst reactivation is achieved whether the catalyst is completely deactivated or partially deactivated. A fluid reactivating agent is employed to dissolve catalyst fouling agents and also to react with such agents and carry away the reaction products. The deactivated catalyst is contacted with the fluid reactivating agent under pressure and temperature conditions such that the fluid reactivating agent is dense enough to effectively dissolve the fouling agents and any reaction products of the fouling agents and the reactivating agent. Useful pressures and temperatures for reactivation include near-critical, critical, and supercritical pressures and temperatures for the reactivating agent. The fluid reactivating agent can include, for example, a branched paraffin containing at least one tertiary carbon atom, or a compound that can be isomerized to a molecule containing at least one tertiary carbon atom.

Inventor: TARDIF PIERRE
IPC: A47J31/20
Filed: 2003-02-12
Abstract: Device having a cover to be positioned on a vessel with an interior wall. A  shaft extends through a transverse passageway in the cover, A basket for holding a flavoring substance is mounted to the end of the shaft. The basket can thus be raised and lowered within the vessel through action of the shaft. A continuous lip of flexible polymer surrounds the periphery of the basket, for engagement with the interior wall of the vessel. With flavoring substance in the basket, liquid is poured into the vessel in such a way as to retain air in the space between the basket and the bottom of the vessel. The basket is pushed downwards, causing at least part of the air retained in the space between the basket and the bottom portion of the vessel to displace the flavoring substance while the air rises within the vessel, resulting in improved infusion of the flavoring substance.

Abstract: Physical items can be digitally watermarked, permitting their recognition by webcams or the like to trigger corresponding actions. Coffee cups and coffee cup jackets are exemplary of items that may be so watermarked. The action triggered by recognition of the item can vary, depending on the context in which the recognition occurred (e.g., store or office). The action likewise vary with time (e.g., triggering a first response when presented a first time, and triggering a second, different, response when presented a second time).  Some such items may have multiple faces (e.g., tow side to a credit card ; six faces to a product carton) - each encoded with a different watermark and triggering a different response.
