Abstract: Study of the change with time in the voltage between an electrode (9) and a metal structure (1) buried in the soil (3) and deemed to be protected against corrosion by an electrical current. For this study, provision is made to momentarily interrupt the flow of the protective current, to read the voltage between the structure (1) and the electrode (9), to pass these readings through an analog filter (11), to smooth these filtered signals by substituting therefor values corresponding to a postulated continuous and monotonic function and then, the said filtering operation having distorted the said signals, to reconstitute mathematically the change in the voltage signals between the structure and the electrode, such as it would be without any analog filter. The invention relates to the study of the cathodic protection of gas pipelines. <IMAGE>

Filed: 1991-02-05
Abstract: A method and equipment for testing the seals and locating any leaks in the supply-exhaust system (A) of an internal combustion engine with fuel injection for motor vehicles. The test is effected by admitting compressed air to the inlet pipe (C) of the engine at a first regulated pressure, detecting the value of the pressure upstream of the inlet pipe, discharging the compressed air from the inlet pipe, and detecting the discharge pressure. The discharge pressure is compared with the supply pressure and, if the former is below a predetermined value, the air-supply pressure is increased so as to identify the location of the leak.

Title: Zero clearance anti-extrusion rings for containment of PTFE packing
Inventor: HUTCHENS WILBUR DEAN
IPC: F16J15/16
Filed: 1991-10-09
Abstract: A packing containment (10) assembly for sealing an operating member such as a shaft (12) or stem in a fluid control valve (14), particularly where PTFE packing (16) is used. A pair of zero clearance anti-extrusion rings (18) of PEEK material are mounted in the shaft with the PTFE packing (16) therebetween. Each ring (18) has an inner diameter slightly less than the shaft (12) outer diameter to form an interference fit. The rings (18) are split with a scarf cut (24) to provide an overlapping joint and enable mounting of the rings (18) on the operating member (12). A male adapter PEEK ring (64) matches a V-type female packing ring (16a) which significantly reduces the amount of PTFE packing (16) needed for a reliable seal. A step cut PEEK zero clearance anti-extrusion ring (18) could be used as well as a fractured carbon ring (50).

Abstract: Méthode d'enrichissement de particules de houille, par exemple de charbon, consistant à former à partir de ce matériau une boue dans une solution aqueuse saline. La boue est séparée dans un cyclone en deux parties, l'une à faible densité et l'autre à densité élevée. La première contient des particules de houille à teneur en soufre et en cendres inférieure à celle des particules de la deuxième. Les particules de houille sont séparées de la première partie, sur laquelle on laisse toutefois un résidu de la solution aqueuse saline. Les particules ainsi séparées, ainsi qu'une partie résiduelle du sel sont utilisées comme combustible pour la production de gaz de houille dont au moins une partie de la teneur en soufre est dégazée sous forme solide par le sel résiduel, ou bien réduite au cours d'un processus de fabrication de charbon extra-pur.

Abstract: Système informatique insensible aux défaillances dont le fonctionnement automatique insensible aux défaillances réduit la fréquence de création de points de reprise tout en ne nécessitant ni simultanéité ni atomicité par rapport aux informations transmises à des moyens de secours. Ces avantages sont mis en oeuvre par un fonctionnement permettant de retarder les transmissions de message à partir de tâches primaires se déroulant sur un processeur de données vers des moyens de secours jusqu'à ce qu'une action soit achevée, laquelle continue après une défaillance du processeur de données. Bien qu'un tel fonctionnement puisse avoir pour résultat le fait que les moyens de secours n'ont pas reçu tous les messages transmis à leurs tâches primaires respectives lorsque la défaillance a lieu, l'on parvient malgré tout a une récupération à l'aide des moyens de secours, puisque la transmission à ces derniers est régulée de manière que tous les moyens de secours s'accordent sur l'état du processeur de données au moment de la défaillance, lequel n'est pas forcément l'état effectif du processeur de données au moment de la défaillance.

Title: Methods and compositions for genetic therapy and potentiation of anti-tumor immunity.
Inventor: FROST PHILIP
IPC: A61K35/12
Filed: 1991-09-12
Abstract: The invention provides a preparation of tumor cell lines containing an exogenous gene encoding a polypeptide that potentiates the immune response to the tumor, for example, interleukin-2. The invention includes methods for cancer therapy by immunization with the immunopotentiating tumor cell. The invention also provides methodology whereby one can selectively ablate in vitro and in vivo genetically altered cells. A preferred embodiment of this aspect of the invention includes a cell containing a first exogenous gene encoding an immunopotentiating polypeptide and a second exogenous gene encoding a "lethal" or "suicide" polypeptide, preferably under the control of an inducible promoter. Introduction of the second exogenous gene confers the ability to selectively kill the tumor cell by inducing a promoter in operative linkage to the gene encoding the lethal polypeptide to initiate transcription of the polypeptide. Diphtheria toxin or the thymidine kinase of Herpes simplex virus are exemplary lethal genes. An exemplary promoter employed is the 6-16 promoter, which is inducible with low levels of interferon. Methods for using the cells in cancer therapy are also provided.

The suction device (6, 21) releases the sheet film (3a) to be removed from a sheet-film stack (3) by bending its front section. The thickness sensor (10, 11, 15, 17) which has a forklike design is spring-biased to move onto the bent area of the sheet film (3a) still located on sheet-film stack (3). The thickness sensor comprises two levers (10, 11) with rollers (15, 17), one lever (11) being pivotable relative to the other lever (10). Depending on its path of pivotal movement the pivotably mounted lever (11) actuates a switch (19). If there is more than one sheet film (3a) between the rollers (15, 17) of the levers (10, 11) switch (19) is actuated which interrupts the sheet-film removal operation and causes its repetition. Even if the removal operation must be repeated several times the sheet film (3a) to be removed remains on the sheet-film stack (3), which prevents it from being subjected to any undesired wear and tear.

IPC: C23C14/04
Filed: 1992-07-27
Abstract: The improved material deposition process of the present invention utilizes a first, low temperature deposition step followed by a second, high temperature/high power deposition step. In the first deposition step a collimation plate (32) is placed between the sputtering target (18) and the substrate (12), such that a collimated stream of sputtered material is deposited upon the substrate (12). The collimated stream provides a seed layer (40) which aids in eliminating voids by partially filling the holes and grooves in the surface of the substrate (12). The second deposition step is conducted as a high temperature sputtering deposition. At the high temperature the sputtered material joins and flows with the seed layer (40), whereby the holes and grooves are more easily filled without voids and an improved planarized layer is achieved.
