Patent CA-2140235-C (CA)
Inventor: KENNEDY BRIAN S
IPC: E21B43/14
Filed: 1995-01-13
Granted: 2005-11-15
Abstract: A scoophead/diverter assembly functions to orient and anchor multiple tubing strings at the Y-juncture in an oil or gas well with multiple lateral wellbores. An important advantage of this arrangement is to provide communication to multiple reservoirs or tap different locations within the same reservoir, and enable re-entry to these wellbores for remediation and stimulation. The large bore of the scoophead enables a secondary wellbore's production tubing (liner) to pass through until the top of the liner is in the scoophead. In order to effect a seal inside the scoophead, a novel offset parallel seal assembly with centralizer is utilized. This parallel seal assembly carries compressive loads on the primary wellbore side, and has a shear out mechanism on the secondary wellbore side. This seal assembly also may constitute the connection between the scoophead and a selective re-entry tool (SRT). The SRT is a tool that ties the two separate tubing strings below it into a single production tubing string to surface or the next lateral. This parallel seal assembly has two seal assemblies parallel to one another with one seal assembly being larger diameter and longer than the other. The larger seal assembly seals into the seal bore of a tie back sleeve which is latched into the scoophead, and is attached to the top of the secondary wellbore's production tubing string. The smaller seal assembly seals in the small bore of the scoophead. The smaller assembly acts to isolate the primary wellbore. The larger seal assembly is longer than the smaller to allow it to enter its bore and align the assembly. The alignment is accomplished by trapping the larger seal assembly in its bore and trapping the centralizer in the wellbore. This positively limits the rotational mis-alignment available to the smaller seal assembly prior to stabbing into the scoophead.

Abstract: La présente invention concerne un système de radiotélécommunications numériques dans lequel les effets néfastes de fading, de la dispersion temporelle et d'interférences survenant au niveau du canal sont limités par l'élimination des interférences et la diversité par commutation. Les signaux numériques représentatifs de séquences de symboles numériques sont transmis par un canal radio dans lequel les signaux peuvent être dégradés par effet de fading, de dispersion temporelle et d'interférence. Les signaux dégradés sont reçus par un récepteur pourvu d'une ou plusieurs antennes. Les signaux reçus sont traités de sorte qu'un train d'échantillons de signaux reçus rd(kTs) soit formé pour chacune des antennes. Les échantillons estimés de signaux reçus pour chacune des antennes sont produits par combinaison pour chaque canal des séquences de signaux hypothétiques et des modèles de signaux. Les échantillons de signaux reçus et les échantillons estimés de signaux reçus sont traités conjointement avec une estimation des caractéristiques de corrélation des altérations permettant de produire des mesures de segments utilisables dans un algorithme de Viterbi ou un autre algorithme d'estimation de séquence. Le processeur de mesures de segments peut se configurer d'une ou plusieurs façons, suivant que le canal est ou n'est pas à variation temporelle.

Abstract: A process for the counter-current extraction of soluble coffee solids.    Soluble coffee solids are extracted from roast and ground coffee in a first extraction stage using a primary extraction liquid at a temperature of 80°C to 160°C. Then soluble coffee solids are extracted from the partially extracted grounds in a second extraction stage using a secondary extraction liquid at a temperature of 160°C to 190°C, the coffee grounds having at least 25% by weight of soluble coffee solids extracted from them. The coffee grounds obtained from the second extraction stage are drained and thermally hydrolysed in a hydrolysis stage at a temperature of 160°C to 220°C for 1 to 15 minutes.  Soluble coffee solids are extracted from the hydrolysed coffee grounds in a third extraction stage using a tertiary extraction liquid at a temperature of 170°C to 195°C to provide extracted coffee grounds and a hydrolysed coffee extract.

Filed: 1997-12-01
Granted: 2001-05-01
Abstract: An Automatic Prescription Pill Dispensing System for home use provides a locked cabinet in which prescription drugs are pre-loaded into a pill array according to the users medication regime using a specially designed pill cartridges. The bottom of the array consists of a series of sliding panels which selectively permit pills to drop into a dispensing location under control of a microcontroller. Certain prescription pills are available upon demand, while other prescription pills are available at preset time intervals only. Visual and audible alarms alert the user when the prescription pills are available to be removed from the dispensing location. A timer ensures that prescription pills which are not removed by the user within a pre-set time are removed from the dispensing location to a holding bin, thus ensuring that pills may only be removed at the appropriate time. Pills are loaded into special pill cartridges, one type of pill per cartridge and stored in a locked drawer in the unit. This pill cartridge approach simplifies the loading of the main pill array. A removable portable unit attached to the main dispensing system provides a day's medication when the user is away, from the main dispenser for the day. A maintenance unit works in conjunction with the main dispenser to set the time and perform maintenance functions on the Main Dispensing System. A pill cartridge loading tray simplifies the loading of the pill cartridges.
