Abstract: Method and apparatus making it possible to obtain a perforation of the wall of a well by the action of a tool, such as an explosive gun. Lowered into the well is a working assembly comprising a perforation tool (4) associated with a measurement housing (5), such as a logging probe and temperature and pressure sensors. The assembly (4, 5) is suspended by means of a connecting cable on a supporting element (8) capable of being locked on the inside of and on the base of a column (1). The column is lowered as far as the working zone and blocked by means of a packer (2). The supporting element (8) and the assembly (4, 5) are displaced by means of a control cable lowered from the surface, and the best locations of the well for carrying out the blasts are determined by means of measurements. Sensors contained in the housing (5) make is possible to monitor the results. After the work has been carried out, the gun (4) is left in the well, and the supporting element (8) and housing (5) are raised in order to open up the interior of the column. The invention is used, for example, for oil-producing wells.

Abstract: The present invention relates to a process for obtaining mechanical energy at an output speed which can be used directly on a shafting or on a receiver machine, without a speed reducer, and which employs a thermal engine with external combustion of a hydrocarbon, having a closed steam circuit and comprising a steam generator 1 connected to a volumetric motor 5, characterised in that a fraction of the steam expanded at medium pressure and coming from said so-called main volumetric motor 5 is transferred for the purpose of actuating turbocompressor means, where the final expansion of the steam takes place, and in that the other fraction of the steam expanded at medium pressure is recompressed in said turbocompressor means, and this recompressed steam is applied to an auxiliary volumetric motor 65 which actuates the auxiliary devices necessary for the operation of the engine; for an anaerobic mode of operation of the latter, the CO2 coming from the generator 1 is compressed in order to liquefy it, and the liquefied CO2 is stored in bottles which previously contained the oxidising oxygen as the latter is consumed. The invention is used in industry and in the marine sector in general with regard to its atmospheric mode of operation and in the submarine sector with regard to its anaerobic mode of operation. <IMAGE>

Title: Site specific in-vivo activation of therapeutic drugs.
Inventor: BREDEHORST REINHARD
IPC: A61K47/48
Filed: 1990-01-23
Abstract: A method for site-specific in-vivo activation of a prodrug in an animal using an activator-targeting moiety conjugate to localize an activator at a predetermined site of use and a prodrug compound that is converted to an active drug in the presence of the activator. In the preferred embodiment, the targeting moiety, the activator, and the prodrug demonstrate little or no immunogenecity in the animal being treated. The targeting moiety is relatively specific for binding to the target tissue than to non-target tissue. The activator is not found or present in only small amounts in circulation or in non-target tissue, does not have a substrate for its activity in circulation or in non-target tissue, can be linked to the targeting moiety, and is capable of converting the prodrug to an active drug. The prodrug is selected for its ability to exert a cytotoxic activity on the target tissue after conversion by the activator.

Abstract: A calcined or sintered material having a basic composition (Pb 1-x La x )(Zr y Ti 1-y ) 1-x/4 O 3 (wherein O < x < 0.25, O < y < 1) is pulverized and is used as a raw material for a support member of the moisture sensor. A plate made of this material having a thickness of 0.5 mm and a size of 6 x 6 mm is sintered at 800 to 1100° C for several hours in the open air to obtain the support member. The support member is immersed in an aqueous solution of alkali metal phosphate of 0.05 mol/I or higher for several seconds, dried, and heat-treated at 600 °C to 900 °C for several hours in the open air so that the entire porous surface is covered with an alkali metal phosphate. As shown in Fig. 1, golden opposing electrodes (2) are formed on both surfaces of the moisture-sensing member (1) by vacuum deposition, and lead wires (3) are attached to the electrodes using an electrically conductive resin adhesive to obtain a moisture sensor of the sandwich structure. The sensor is left to stand several days under high-temperature and high-humidity conditions (60 to 90 ° C, 80 to 95 % RH). At a temperature of 30 C, the sensor exhibits an impedance of 1 MQ when the relative humidity is 0 % and 3 MQ when the relative humidity is 90 %, which is a region suited for assembling a measuring circuit, and further exhibits very little aging and very small temperature coefficient.

Abstract: A detector path insertion verification system for use with flux mapping of a pressurized water nuclear reactor uses a transfer insertion switch (54) at the input of each multiple-path selector (30) to detect insertion of a detector into the multiple-path selector (30). No insertion switches are used at the output of the multiple-path selectors; instead software is used to verify the position of the multiple-path selectors. The sensed actual position of each multiple-path selector is monitored as the multiple-path selector is rotated to verify that the sensed actual position passes through the expected sequence of positions in an expected amount of time. The multiple-path selectors are rotated until a sensed actual position is equal to a desired position and rotation is stopped. After the passage of a short period of time, the actual and desired positions are again compared and if equal, insertion is begun. When the transfer insertion switch (30) detects insertion of the detector into the multiple-path selector, the actual and desired positions are again checked and insertion of the detector is continued only if the actual and desired positions are still equal.

The gasket may provide moderate surface pressure at a portion slightly away from the hole (Hc) to be sealed to prevent deformation of the engine parts. High surface pressure may be formed near the hole to be sealed.
