Patent CA-2261518-A1 (CA)
Inventor: SPENCE RUPERT EDWARD VON HAKEN
IPC: C07F9/535
Filed: 1999-02-12
Abstract: A process to prepare a bulky trialkyl aminophosphonium halide by the reaction of a precursor dihalide with ammonia. The reaction is facile and may be completed under mild reaction conditions. The bulky trialkyl aminophosphonium halides produced by the process of this invention may be utilized in the preparation of ligands for organometallic complexes (preferably using group 4 metals) which are highly active olefin polymerization catalysts. Prior art methods to prepare such organometallic complexes use an azide as an intermediate. Azides require special expertise to handle on a commercial scale and may explosively decompose. The present synthetic method avoids the use of azides.

Title: Process for making pen/pet blends and transparent articles therefrom
Inventor: SCHMIDT STEVEN L
IPC: C08G63/80
Filed: 1997-12-05
Abstract: Process for controlling the change of intrinsic viscosity and transesterification during solid stating of a polyethylene terephthalate (PET) and polyethylene naphthalate (PEN) blend, with an effective amount of an alkylene glycol compound. The process enables the production of a copolymer based on predefined initial and final IV's and final transesterification level, by varying the solid-stating time and/or effective amount of alkylene glycol. In one embodiment, a relatively greater amount of post-consumer PET (e.g., 70 %) having an IV of on the order of 0.72-0.73, is incorporated in the blend to provide a final IV on the order of 0.80-0.85, and a moderate, controlled level of transesterification; the blend is used to injection mold a sleeve layer of a preform. In another embodiment, a substantially transparent neck finish for a preform is made from a PEN/PET blend having an amount of alkylene glycol which enables substantial transesterification, without excessive increase in IV.

Abstract: Des paquets de pixels reliés de même couleur sont identifiés dans une page à trames. Les paquets ayant au moins une taille prédéterminée, correspondant typiquement à des objets texte ou dessin au trait, sont soumis à une compression sans perte. Les paquets ayant une taille inférieure à la taille prédéterminée, correspondant typiquement à des objets image ou photo, sont sensiblement soumis à une compression avec perte. La taille prédéterminée du paquet de pixels commande le mélange des techniques de compression sans perte et de compression avec perte. On obtient la compression optimum en maximisant la compression sans perte, tout en atteignant un taux de compression ciblé. Parmi les différentes fonctions, on trouve la reconnaissance et le codage efficaces des paquets de pixels, le traitement perfectionné des limites entre les pixels comprimés sans perte et les pixels comprimés avec perte, la commande adaptative du taux de compression et les possibilités de compression avec récupération d'erreur.

Title: Fore and aft movement of a pickup reel of a crop harvesting header
Inventor: SHEARER BRUCE R
IPC: A01D57/04
Filed: 1999-10-01
Abstract: A crop harvesting header includes a reel mounted on a pair of forwardly extending arms carried on a header frame above a table and cutting knife. The reel is rotatable about a longitudinal axis and includes bats with fingers which pivot each about a respective bat axis so the angle of the fingers varies as the reel rotates. The angle of the fingers can be varied to increase and decrease the angle at the knife. The arms include a forward portion which is arranged at an angle to a main portion so as to be inclined downwardly and forwardly therefrom. As the reel supports on the arms is moved forwardly along the arms and engages onto the forward portion, the reel is moved downwardly and forwardly which simultaneously changes the angle to provide a more aggressive action as the reel is moved forwardly of the knife.

Patent CA-2299401-A1 (CA)
Title: Process and apparatus for water decontamination
Inventor: MCNEILLY MICHAEL
IPC: C02F1/78
Filed: 1998-08-06
Abstract: Oxidizable contaminants in water are destroyed rapidly and efficiently by exposing the water to oxidizing conditions under pressure. Specifically, a single dose of hydrogen peroxide may be injected into the water, followed by the repeated injection and mixing of low doses of ozone. In each such high intensity mixing/reaction stage, ozone is injected at a pressure, velocity, and direction approximately matching that of the contaminated water flow. High intensity mixing under pressure facilitates rapid and complete oxidation of the contaminants with minimal stripping of volatile contaminants and waste of undissolved ozone. Residual ozone levels after high intensity mixing may be carefully monitored and minimized by adjusting the injection of hydrogen peroxide and ozone in order to suppress the formation of bromate. Additional contaminants may be removed by passing the treated water through activated carbon beds.
