Title: Clamp for device box
Inventor: BOURASSA ALAIN
IPC: H02G3/08
Filed: 1996-03-29
Abstract: A clamp for use to fix nonmetallic sheathed or armored cables within an electrical device box. This clamp has an L-shaped body with a forwardly projecting front wall and an upwardly projecting rear wall. The front wall has a central hole and a rectilinear front edge of a given length that is parallel to the rear wall. An integral U-shaped element projects from the front edge of the L-shaped body along the full length of it. Two upwardly embossed portions are made in the front wall. These portions are symmetrical with respect to the central hole and each has a semi-cylindrical cross-section with an axis perpendicular to the rear wall. Each embossed portion ends at a short distance from the rear wall and defines therewith a locking ridge. Two front openings are made in the front wall at the junction of the embossed portions with the front edge of the body. In use, fixation of the clamp within the device box with a screw inserted into the central hole of the front wall of the clamp allows one or two cables to be squeezed and thus be fixed either between the U-shaped element, the corresponding locking ridge and the adjacent wall of the box when the cable is of the nonmetallic sheathed type, or within one of the embossed portions when the cable is of the armored type.      Advantageously, a forwardly and downwardly projecting tab can be provided in the rear wall of the clamp, to retain the screw used to fix it into the device box.

Abstract: A method of determining an amount of dissolved gas in a fluid sample is disclosed. The method includes hydraulically confining and expanding the sample while measuring pressure and volume. A first volume and pressure are determined at which the rate of change in pressure with respect to volume deviates from a linear relationship. A second volume and pressure at which continued expansion of the fluid causes substantially no change in pressure is determined The first pressure and volume are extrapolated by the linear relationship to intersect an extrapolation from the second volume and pressure at no change in pressure, thereby determining a bubble point comprising a bubble point pressure and a bubble point volume. A third pressure corresponding to measured pressure of the fluid sample at the bubble point volume is determined. An extrapolated sample volume is determined at the third pressure byextrapolating the linear relationship from the bubble point to a sample volume along the linear relationship corresponding to the third pressure. A volume of gas dissolved in the fluid sample is determined by linearly scaling a difference between the bubble point volume and the extrapolated sample volume with respect to a difference between the second volume and the bubble point volume. In a preferred embodiment of the invention, the sample is withdrawn into a sample chamber in an electric wireline formation test tool having a means for measuring pressure and volume of the sample chamber.

Filed: 1996-11-04
Abstract: A cellular telephone subscriber who wishes directory assistance services is connected in the conventional manner to an operator who identifies a destination telephone number desired by the subscriber. As in the prior art, the operator then initiates a call connecting the subscriber to the destination telephone number. In a preferred embodiment, the operator locates a desired destination telephone number in a computer database, and can select automatic dialing of the located number. Further, rather than dropping all further involvement with the call, the preferred embodiment of the present invention continually monitors the connection thereby established for a predetermined DTMF signal issued by the customer, such as that obtained by pressing the "*" button. If such a signal is detected, the customer is transferred to a directory assistance operator, who can then provide whatever further assistance is needed (e.g. redialing a busy number, or providing further directory assistance). This feature can be disabled, manually or automatically, if the destination number makes its own use of the DTMF signals.

Abstract: The invention increases the effectiveness of chemotherapeutic agents in treatingsolid tumor cells. The cyclin dependent kinase inhibitor p27Kip1 is a major regulator of the drug resistance of solid tumors, and resistance is increased by high levels of intracellular p27Kip1. Tumor-targeted p27Kip1 inhibitors are therefore useful as chemosensitizers in treatment of slow growing solid tumors. The invention relates to products which are p27Kip1 inhibitors that can downregulate or inactivate p27Kip1, decrease cell adhesion, increase cell proliferation, increase susceptibility to spontaneous, drug or irradiation induced cell death and reduce or prevent tumor resistance to anticancer compounds. These products may be used in pharmaceutical compositions. The invention also relates to the use of the p27Kip1 inhibitor and a method for using p27Kip1 inhibitor as a chemosensitizer and a regulator of drug resistance of solid tumors. The invention includes a method for screening anti-cancer agents which are preferentially active against slowly dividing cells or which chemosensitize solid tumors.
