Title: Organophilic clay additives and oil well drilling fluids with less temperature dependent rheological properties containing said additives
Inventor: DINO DAVID
IPC: C09K8/32
Filed: 2001-03-09
Abstract: Conventional organophilic clays, when used as rheological additives in oil based invert muds, display marked viscosity loses in the mud when these muds are heated much above 350° F, whereas muds prepared according to the present invention are dramatically more viscosity stable at temperatures through 500.DELTA. F. The present invention relates to the discovery of oil based invert emulsion drilling fluids that provides more stable drilling fluid viscosity and anti-settling performance over varying temperatures when compared to conventional fluids containing organoclays. As a result, the inventive fluids of this invention are ideal candidates for high temperature applications. This invention in another aspect of this invention is a process for improving the rheological properties of oil well drilling fluids particularly useful for oil- based invert emulsion types of drilling fluids. The new process uses as a rheological viscosifer for such fluids as a specific organoclay which when added to a drilling fluid at from about 0.5 and 5% by weight creates an inventive drilling fluid composition less sensitive to the very hot temperatures found in the drilling hole, and in the long stem of drilling pipe.

Abstract: Means for providing anonymity in a Voice-over IP (VoIP) telephony network for calls established between a calling endpoint 120 and a called endpoint 130. The calling and called endpoints 120, 130 have respective IP addresses and can be under the control of a single IP call server 110 or separate IP call servers 110, 310. An IP address is obtained from a network address translator 150 that is operatively connected to the IP call server 110.      The IP call server 110 then substitutes the IP address of the calling endpoint 120 with the IP address obtained from the network address translator 150 in all call signaling messages intended for the called endpoint 130. Conversely, the IP call server 110 substitutes the IP address obtained from the network translator 150 with the IP address of the calling endpoint 120 in all call signaling messages intended for the calling endpoint 120. The end result is the setup and establishment of a VoIP call between the endpoints 120, 130 in which the actual IP address of each endpoint is unknown to the other.

Abstract: La future génération de CD réenregistrables (CD-RW) à grande vitesse destinés à l'enregistrement à grande vitesse (4x-10x) nécessite une nouvelle stratégie d'écriture qui ne convient pas à l'enregistrement à des vitesses plus réduites (1x-4x). Les graveurs de CD-RW actuellement disponibles pourraient accepter ces disques et les enregistrer conformément aux stratégies d'écriture existantes, mais les disques seraient impossibles à lire. Afin d'empêcher cela, une zone d'étalonnage de puissance et une zone de mémoire programme, toutes deux nécessaires à l'enregistrement, sont masquées pour les graveurs actuellement disponibles. De ce fait, le disque sera rejeté. Dans un mode de réalisation consistant à appliquer une référence temps absolu sur le disque. Les emplacements de démarrage de ces zones sont déterminés par un décalage temporel fixe par rapport à une zone de départ postérieure. Un mode de réalisation consiste à faire en sorte que la zone d'étalonnage de puissance et la zone de mémoire programme ne puissent pas être suivies, par introduction d'un temps absolu d'une minute, par exemple, dans un saut de code temporel gravé, juste avant le temps de démarrage de la zone de départ. Un autre mode de réalisation consiste à introduire le temps absolu dans des sauts de code temporel gravés entre une zone de test et une zone de comptage de la zone d'étalonnage de puissance.
