 Appl.No PCT/US1999/001562 Applicant WESTERN ATLAS INTERNATIONAL, INC. Inventor AMBS, Loran, D.
A system for drilling a slender borehole through geologic formations. The system comprises a hollow drill pipe (20) having a drill bit (26) for maintaining gauge of the borehole. A pulsed generator (10) such as a homopolar generator provides the power for operating a downhole rail gun (12). One or more projectiles (14) are accelerated by the rail gun to impact the geologic formations and to extend the borehole length. A plasma generating material (38) is attached to the projectiles to generate a plasma for accelerating the projectiles, and the projectiles can include a secondary explosive for impacting the geologic formations. A controller controls the operation of the rail gun in cooperation with the drill rate to provide interactive control over the firing rate and the energy of projectiles impacting the geologic formations.

 Appl.No PCT/UA2002/000051 Applicant PECHERITSA, Konstantin Arikovich Inventor PECHERITSA, Konstantin Arikovich
The invention relates to the oil-gas production industry and can be used for stimulating wells by increasing the permeability thereof. The inventive method consists in supplying an acid in an inactive form to a formation. Said invention is characterised in that titanium chloride hydrates having the general formula TiCl4 nH2O, wherein n=1.5-2.5, are used as an acid in an inactive form. Said hydrates have a crystalline structure with bulk density of 1.1 g/cm3 and the content of active chlorine hydrate ranging from 56 to 60 %. Said invention makes it possible to extend the radius of the zone of penetration of the acid into the formation matrix, thereby increasing the penetration of the formation and the efficiency of the treatment of a bottom-hole formation zone.

The present invention pertains to the field of locking devices and more precisely relates to cylindrical mechanisms which can be used in various lock structures such as door locks. This cylindrical lock mechanism includes a drum having a groove formed therein, wherein fixation plates (3) capable of vertical displacement are mounted in said groove. These plates comprise rectangular openings whose lead-in contact surfaces are located under the key. When the lock is in a locked position, said openings extend horizontally and are vertically offset relative to the centre of the plates. Each plate has its own eccentricity. The inner surface of the drum comprises a plurality of diametrically opposed slots. This invention can be used for simplifying the mechanism structure and for reducing malfunction risks.

 Appl.No PCT/US1998/014377 Applicant GENERAL MONITORS, INCORPORATED Inventor BALIGA, Shankar
Apparatus for the optical detection of selected toxic gases, using the ultraviolet region of the electromagnetic spectrum, and the known absorption properties of the toxic gases in the ultraviolet region. An ultraviolet flashlamp source illuminates a straight, highly polished metal tube with numerous perforations to permit access for the gas to be detected. The ultraviolet light then enters an optical compartment comprising an optical beamsplitter and two ultraviolet detectors with wavelength selective narrowband filters attached. The filters are selected so that one overlaps the region of absorption by the gas while the second is in a region where there is no absorption by the gas. The electronic circuit following the ultraviolet detectors and the drivers for the flashlamp, are timed by a microprocessor that provides the means for the electronics and data processing to be synchronized with the flashlamp pulse. The concentration of the absorbing gas is calculated from the output of the two detectors including the dark outputs measured while the flashlamp is turned off. By this method a part per million sensitive toxic gas sensor useful to measure gases such as hydrogen sulfide, sulfur dioxide and benzene is obtained.
