Patent CA-2140234-A1 (CA)
Title: Scoophead running tool
Inventor: KENNEDY BRIAN S
IPC: E21B23/06
Filed: 1995-01-13
Abstract: A scoophead/diverter system is run into a wellbore using a novel scoophead running tool. The running tool allows circulation through its inside diameter, and has internal pressure integrity to test any seals below the running tool prior to releasing the scoophead. This also allows circulation while running in order to apply MWD techniques. This run-in tool includes a mounting head from which extends a running stump and a housing (or connecting mandrel) parallel to the running stump. The running stump and housing are sized and configured to be respectively received in large and small diameter bores in the scoophead. The scoophead running tool thus allows torque to be transmitted about the centerline of the scoophead assembly in spite of being attached into one of the offset bore. This torque transmission is accomplished by connecting the connecting mandrel between the running tool and scoophead at the same offset as the large bore of the scoophead. This transfer of torque is important in order to reliably manipulate the scoophead assembly with the running string. The connecting mandrel of the running tool has an internal bypass sleeve that opens at a predetermined pressure that allows a tripping ball to be circulated down to its seat if the scoophead is to run and be anchored into a closed system. This is necessary when having to hydraulically manipulate other equipment (which mandates a closed system) downhole prior to installing the scoophead. Once the bypass sleeve is shifted to allow circulation, the circulation can only continue until the ball is seated. At that time, the circulation ports are once again closed off from above, and increased tubing pressure will release the running tool.

Title: Ethylenic oxygen scavenging compositions and process for making same by esterification or transesterification in a reactive extruder
Inventor: CHING TA Y
IPC: C08K5/57
Filed: 1994-07-13
Abstract: Disclosed is a process for transesterifying a polymer having a polyethylenic backbone and pendant ester moieties comprising contacting a melt of the polymer in a reactive extruder with a transesterifying compound so that the polymer undergoes transesterification but not alcoholysis. The transesterified polymer also has pendant ester moieties which differ in kind and/or number from the unreacted polymer.

Title: Rescue tool
Inventor: HICKERSON WILLIAM
IPC: B66F3/00
Filed: 1993-09-20
Abstract: A light weight, quiet and emergency safe, portable "jaws of life" spreading tool (10) actuated by an electric motor (13). Full high torque at any position, with selectable spreading or cutting motions under high loads is achieved by the use of a rotary, multiple stage, speed reducing gearbox driven by the motor. The gearbox contains an input stage (14) from the electric motor running on a 12 volt DC power supply, and a compound planetary output stage (18). The arms or jaws (12a, 126) of the device are separately driven by the planetary or spindle gears and, for convenience, are attached to external rings on the gears, by heavy duty pins (30). The arms or jaws are removable for interchanging between cutting and spreading configurations, or replacement with general purpose arms capable of both cutting and spreading operations.

Title: Outline programming for developing communication services
Inventor: MARANTZ LYN R
IPC: G06F3/0486
Filed: 1995-04-12
Abstract: With only an understanding of the functionality to be provided by a service, one can quickly and easily develop or create such a service by, in accordance with the principles of the invention, selecting and arranging instantiations of predetermined "pictures", e.g., icons, into a multilevel outline which generallyspecifies the service logic of the desired service. Each picture represents a "service building block", e.g., a high level process part and its customizable attributes, and for each instantiation of a picture in the multilevel outline there exists a corresponding instantiation of a service building block. The operation of the instantiations of the service building blocks are customizable in response to attributes supplied by the service creator. A service development system arranges instantiations of the service building blocks, in response to the operations on the pictures, to develop a program that implements the service logic as specified by the multilevel outline. The display of the graphical multilevel outline may be expanded or collapsed by the service creator for viewing convenience without affecting the service logic or attributes of the corresponding service.

IPC: G06F3/045
Filed: 1993-12-08
Abstract: The data input device is provided with an input surface (40) which, by means of a pen, a writing instrument or the like, is locally subjected to a pressure or a pressing force. Below the input surface, there is arranged a sensor means for detecting at least the current position of the pen or writing instrument and for outputting output signals representing said position. Between the input surface and the sensor means, a color-change layer (50) is provided for temporary optical display of the position on the input surface (40) run over by the pen, writing instrument (30) or the like. The color-change layer (50) is responsive to the writing pressure exerted by the pen, writing instrument (30) or the like, and changes its color in those regions of the input surface which are run over by the pen, writing instrument (30) or the like. After lapse of a predetermined length of time after the input surface has been touched by the pen, writing instrument (30) or the like, the color-change layer (50) resumes its condition prevailing prior to said touch.

Filed: 1995-06-15
Abstract: La présente invention concerne un stratifié tel qu'un panneau de garnissage de porte capable de conserver ses qualités de cohésion sur une longue période par association unitaire d'un élément de base et d'un élément de finition. Selon le procédé, l'élément de finition ne se présente pas sous forme de feuille, et il n'y a besoin d'aucun adhésif pour assujettir l'élément de finition. En outre, ce procédé de fabrication permet de réduire la quantité de matériaux à utiliser et de simplifier le processus de fabrication. Le procédé consiste à mouler un élément base poreux (11) épousant la forme du panneau de garnissage de porte, à appliquer sur la surface de l'élément base poreux (11) une résine liquide (12) devant constituer l'élément de finition. La compression des deux éléments l'un contre l'autre entre deux moules (31, 32) provoque le durcissement de la résine liquide (12) qui imprègne au moins la partie visible de la façade intérieure de l'élément base poreux (11). L'effet d'ancrage assujettissant la résine constituant l'élément de finition (12) à l'élément de base poreux (11) du panneau de garnissage de porte réalisé selon le présent procédé, en garantit la résistance.
