Title: Procede et appareil d'impression de donnees variables
Inventor: PARDO LUIS TRABB
IPC: H04N1/387
Filed: 1998-09-01
Abstract: L'invention concerne une technique destinée à ajouter des données variables à un travail d'impression, cette technique ne nécessitant qu'une quantité minimum de stockage. Cette invention repose en particulier sur l'utilisation d'un algorithme de compression de données pendant la conversion effectuée par le processeur RIP. Dans une première étape, ce RIP convertit un document de référence en un format de compression avant de le sauvegarder dans une antémémoire, par exemple une mémoire RAM ou une mémoire à disques. Cette conversion et cette compression de données se déroulent simultanément, de manière à limiter la quantité de puissance de traitement nécessaire pour convertir et comprimer un gros document, et à diminuer considérablement la quantité d'espace de stockage nécessaire pour sauvegarder le document de référence converti par le RIP. Le document contenant des données variables est converti et comprimé au cours d'une seconde étape, au moyen du même algorithme que celui appliqué au document de référence. Ce document contenant des données variables est converti par ledit RIP directement sur le document de référence en format de compression. Pendant cette seconde étape, ce document de référence destiné à être personnalisé est extrait de la mémoire et stocké dans une mémoire d'images. Le document contenant des données variables est converti par le RIP en un format de compression, directement sur la mémoire d'images, le fichier comprimé ainsi obtenu pouvant être décomprimé et transmis au dispositif d'impression.

Title: Method and apparatus for resurfacing anvil blanket of a rotary diecutter for box making machine
Inventor: POLIKOV YURY
IPC: B31B50/20
Filed: 2000-06-09
Abstract: A rotary die cuter for a box making machine has an abrading cylinder mounted for rotation alongside the anvil for engaging and resurfacing the blanket of the anvil on a virtually continuous basis to smooth, level and even the surface of the blanket. This resurfacing occurs during normal operation of the rotar y die cutter so no production is lost. The abrading cylinder has a sheet layer of abrasive material spirally wrapped on the surface of the cylinder and bonded thereto with adhesive material on the backside of the sheet layer. The abrading cylinder is movable towards or away from the anvil by a servo motor and gearbox. The position of the abrading cylinder relative to the anvil is determined by an encoder which sends the information to a computer or programmable controller which calculates the changing diameter of the blanket and the amount of speed chan ge that must be imparted to the anvil to compensate for its changing diameter. The computer or programmable controller is connected to a drive system of the anvil to effect the speed change.
Patent CA-2311718-A1 (CA)
Inventor: COLODETTE JORGE LUIZ
IPC: D21C9/10
Filed: 2000-06-13
Abstract: The invention configures a process for delignifying pulp wherein one stage of a two stage oxygen delignification plant is obviated. In particular, a pulp soak stage enables a pulp stream to be mixed with an alkali feed and held in residence for a sufficient period of time to allow an alkali hydrolysis leaching of colored materials from the pulp and a swelling of the pulp fibers. Next, the pulp stream is combined with an oxygen feed and is processed through a mixer. The output of the mixer is fed to a pressurized reactor where oxygen reacts with lignin of the pulp fibers. The swelled pulp fibers facilitate the oxygen reaction with lignin and removal of additional colored materials.

Title: Medicinal products created from cannabis using cannabinoid profiles as indicators of efficacy
Inventor: SUTHERLAND MARTIN D
IPC: A01H6/28
Filed: 2000-09-27
Abstract: A process is described whereby a back-crossing protocol is used to create cannabis plants which are further standardized into medicinal products. A specific lighting regime is first used to bring a cloned plant to the vegetative stage followed by treatment with defined type of Gibberellic Acid (GA3) which stimulates sex reversal; from a female to a male. The pollen from this new male is used to pollenate the mother plant with her own pollen. This procedure creates a new variety of true breeding plant with a reproducible genome, which can be cloned into more plants. Confirmation of reproducibility is achieved us Gas Chromatography/ Mass Spectroscopy (GC/MS) to determine the Cannabinoid Profile of the pollenated plant. This cannabinoid profile is used as an index for the type of medicinal product which can be produced. Once this profile is established the raw material is gound into a powder, the cannabinoid profile is re-verified and the powder can be used as a medicine for symptom relief from many different ailments such as epileptic siezures, glaucoma, nausea/pain, multiple sclerosis tremors, migraine, fibromyalgia, hepatitis, depression, anorexia, anxiety. Route of administration of this powder can be made either oral or by smoking.
