Title: Method and apparatus for testing oilfield tubular threaded connections
Inventor: PENISSON DENNIS J
IPC: G01M3/36
Filed: 1995-04-11
Abstract: Equipment and techniques test the integrity of one or more seals within an oilfield tubular threaded connection.  A test fixture may be utilized including three axially spaced sensors which are each responsive to radial deformation of an outer surface of an internally pressurized threaded connection. Excessive radial deformation indicates a failure of at least one of the threaded connection seals.   A relatively simple yet highly reliable technique is provided for quickly and easily determining the sealing integrity of a threaded connection made up at a well site.  If any one of the multiple seals fails during the test, the operator may either break out and re-test the connection, or may make up and test a new threaded connection. The present invention may be used for substantially increasing the integrity of oilfield tubular connections and thereby reducing the overall cost of hydrocarbon exploration and recover operations.

Title: Process for the manufacture of thioglycolic acid
Inventor: BERGFELD MANFRED JOSEF
IPC: C07C319/02
Filed: 1996-12-16
Abstract: A process is described for the manufacture of thioglycolic acid by the conversion of monochloroacetic acid with hydro-gen sulfide under pressure in the presence of tertiary amines in solution, whereby care is taken that the partial pressure of hydrogen sulfide over the reaction medium is at least 2 bar up to the end of the reaction, and the thiogly-colic acid formed as an ammonium salt is released by means of acid. The partial pressure of hydrogen sulfide can be maintained by linking the reaction chamber with a source of hydrogen sulfide under pressure during the conversion.
Patent CA-2194535-A1 (CA)
Inventor: OU WAHO
IPC: H04B1/707
Filed: 1997-01-07
Abstract: An anti-saturation circuit controls the gain of a variable-gain element in the front-end section of a receiver, responsive to a desired signal strength indicated by an indicator signal.  The gain of the variable-gain element varies monotonically over a certain range, being reduced as the desired signal strength increases, in order to avoid intermodulation of the desired signal with an interfering signal.  If the receiver also has an automatic-gain-control circuit, the automatic-gain-control signal is adjusted to compensate for the changing gain of the variable-gain element.

IPC: C08L75/04
Filed: 1997-04-25
Abstract: A polyurethane foam comprising a polyurethane foam matrix having disposed therein polyvinyl chloride in particulate form having an average particle size of less than about 25 µm, the polyvinyl chloride being at least partially modified. A process for producing the polyurethane foam is also described. A polyol dispersion useful in the production of the polyurethane foam comprises a particulate solid material dispersed in a polyol, the particulate solid material being present in an amount in the range of from about 1 to about 70 percent by weight of the polyol dispersion, the particulate solid material consisting essentially of from about 1 to 100 percent by weight of polyvinyl chloride and from 0 to about 99 percent by weight of a second solid, the polyvinyl chloride having an average particle size of less than about 25 µm. A process for producing the polyurethane foam is also described. It is suspected that a potential chemical inter-reaction between the partially modified polyvinyl chloride and the nascent polyurethane plays a large role in the enhanced load properties of the polyurethane foam.

Title: Method and apparatus for shaping processing in which discard of atm cell effectively performed
Inventor: OHASHI SATOSHI
IPC: H04L47/22
Filed: 1997-11-04
Abstract: In a shaping processing apparatus which receives ATM cells as reception ATM cells which contains normal ATM cells and tagging ATM cells, a scheduling unit calculates a transmission time of the reception ATM cell based on a transmission time of a previous ATM cell belonging to a same connection as the reception ATM cell and transmitted immediately before the reception ATM cell and a predetermined time interval.  A cell identifying unit identifies a connection number and cell priority of the reception ATM cell.  The normal ATM cell has a higher cell priority than the tagging ATM cell.  A mapping unit maps the reception ATM cell into a managing table based on the transmission time of the reception ATM cell to store the connection number and cell priority of the reception ATM cell in a storage area of the managing table.  The managing table is associated with transmission times.  The mapping unit outputs an address corresponding to the storage area as the write address to a shaping processing buffer such that the reception ATM cell is stored in the shaping processing buffer.
Patent CA-2221285-A1 (CA)
Title: Exit spark control for an electrosurgical generator
Inventor: BEK ROBIN B
IPC: A61B18/12
Filed: 1996-06-03
Abstract: An electrosurgical generator (10) is disclosed that includes an exit spark control system. Exit sparking occurs when energy arcs to the patient (13) as the active electrode (12) is withdrawn from the patient (13). A basis for controlling the exit spark is to automatically change the frequency at which the final amplifier is driven whenever the conditions for an exit spark are detected. The change in frequency acts to lower the gain and efficiency in the final amplifier and dissipate energy as heat. The exit spark control system includes a frequency adjustable waveform generator (14) and a logic capability for determining the conditions when exit sparking is likely to occur. Sensors and an algorithm in a microcontroller (16) are preferably required to detect the conditions preceding exit sparking occurrence. It is further preferred that, the algorithm also controls the sequencing of events: first stopping the electrosurgical output to prevent an arc from initiating and then changing the driving frequency appropriately to dissipate excess stored energy. The output waveform may be stopped for only a short time or the surgeon will detect drag while cutting through tissue.

Title: Tape roll liner/tab, application apparatus and method
Inventor: JACKSON JEFFERY N
IPC: B65H19/22
Filed: 1996-05-29
Abstract: A method and apparatus (20) for forming coreless rolls (15) of pressure sensitive adhesive tape involves the use of a mandrel assembly (55) having a specific circumferential tape supporting segment (234) thereon for winding tape. The circumferential tape supporting segment (234) has a tape engaging surface portion (246) that, in a radial orientation, is compressible yet sufficiently stiff to support the tape as it is successively wound about the mandrel (55) to form a tape roll (15), and that is sufficiently pliant to permit ready axial removal of a wound tape roll (15) from the mandrel (55).  The innermost wrap (72) of pressure sensitive adhesive tape about the mandrel (55) is masked by an adhesive liner (73). That liner (73) is formed from one portion of a liner/tab strip (123) which had been applied to the tape previously, and prior to winding, the tape is severed, and the remainder of that liner/tab (76) forms an end tab on the outermost end (75) of the previously formed coreless tape roll (15). The liner/tab strip (123) is applied by advancing the liner/tab material (90) laterally across the advancing web of pressure sensitive tape (26) adjacent a first, adhesive bearing side (27) thereof, cutting the liner/tab material (90) to a length approximating the width of the web (26), urging the leading lateral edge portion (190) of the cut liner/tab strip (123) against the first, adhesive bearing side (27) of the advancing web (26) and urging the remainder of the liner/tab strip (123) against the advancing web (26) as the web (26) carries the liner/tab strip (123) away.

Patent CA-2229474-A1 (CA)
Inventor: PARRIS GENE EVERAD
IPC: C07C41/01
Filed: 1998-02-13
Abstract: The present invention pertains to a process for the coproduction of methanol and dimethyl ether (DME) directly from a synthesis gas in a single step thereafter, the "single step DME process"). In this process, the synthesis gas comprising hydrogen and carbon oxides is contacted with a dual catalyst system comprising a physical mixture of a methanol synthesis catalyst and a methanol dehydration catalyst. The present invention is an improvement to this process for providing an active and stable catalyst system. The improvement comprises the use of an aluminum phosphate based catalyst as the methanol dehydration catalyst. Due to its moderate acidity, such a catalyst avoids the coke formation and catalyst interaction problems associated with the conventional dual catalyst systems taught for the single step DME process.
