Patent CA-2222788-A1 (CA)
Inventor: AKHAVAN-TAFTI HASHEM
IPC: C07C323/15
Filed: 1996-06-19
Abstract: Vinyl sulfides bearing protected arlyoxy substituents and a process for their preparation are provided. In the process a vinyl sulfide is formed by coupling a ketone compound and a thioester compound with a low valent titanium reagent to form both carbon-carbon bonds in the same step. The vinyl sulfide compounds are useful as intermediates which are convertible into triggerable sulfur-substituted dioxetanes by addition of oxygen to the double bond. The sulfur-substituted dioxetanes additionally are useful for producing chemiluminescence or for further conversion into triggerable alkoxy, alkenyloxy, alkynyloxy, aryloxy, aralkyloxy or acyloxy-substituted dioxetanes. Triggerable dioxetanes are useful for producing chemiluminescence and in detecting activating agents in assays such as immunoassays and nucleic acid hybridization assays.

Title: Separation systems and methods
Inventor: GILDERSLEEVE MICHAEL R
IPC: B01D65/08
Filed: 1996-06-28
Abstract: A vibratory separation system having a drive mechanism for imparting a vibratory motion to a membrane module to enhance filtration. The membrane module comprises one or more filter elements secured to one another, each having a permeable membrane.

Title: Subscriber reward method
Inventor: SAFRAN STEVE L
IPC: H04M15/00
Filed: 1998-03-25
Abstract: A subscriber (12) of a communications carrier is rewarded upon meeting certain criterion. Upon receipt of the subscriber's call, the carrier accesses a profile for the subscriber indicative of the subscriber's relationship with the carrier. Based on the information in the profile, as well as any external criterion the carrier may impose, the carrier determines whether the subscriber is eligible for a reward, and if so, then provides an announcement of the reward during the call. The carrier then provides the reward, which may be a reward of communications of service.

Patent CA-2253122-A1 (CA)
Inventor: GARTON HAROLD W
IPC: B65D5/36
Filed: 1998-11-06
Abstract: An octagonal bulk box well suited for use in pallet storage and transportation of large quantities of flowable solids has a construction allowing the box to be instantly manually erected by the end user. A box precursor which is erectable from a substantially flat condition to form the box is formed of a main blank providing the sidewall panels of the box and a floor blank from which the entire box floor structure is constructed. By forming the entire floor from a floor blank separate from the main blank it is possible to reduce material expense and waste, since the entire floor blank can be constructed of fiberboard lower in strength and cost than that required for the sidewalls. The floor blank is attached to the main blank by connecting flaps extending about substantially the entire lower perimeter of the box walls, on an outside thereof. This configuration serves to reinforce the lower perimeter of the box sidewalls against the large outward bulge forces generated by flowable loads, particularly in the lower third of the box.

Title: Method of borehole compensation of earth formation characteristic measurements using depth measurements
Inventor: HSU KAI
IPC: G01V1/46
Filed: 1998-11-16
Abstract: A method is disclosed for borehole compensation of measurements of earth formations penetrated by a borehole including differential time (.DELTA.t) measurements obtained from a borehole tool in the formation. The borehole tool includes at least one transmitter and a plurality of receivers spaced apart from each transmitter. Each transmitter generates a waveform, and the receivers are responsive to the waveform. A receiver array .DELTA.t measurement is generated for a depth interval spanned by the receivers by cross-correlating receiver array waveforms relevant to the spanned depth interval. A synthesized transmitter array .DELTA.t measurement corresponding to the spanned depth interval is generated by cross- correlating selected transmitter array waveforms. The transmitter array waveforms are selected corresponding to the spanned depth interval by identifying the receiver arrays whose transmitter locations fall within the spanned depth interval and identifying a set of waveforms from the identified receiver arrays to obtain the transmitter array waveforms. The receiver array .DELTA.t measurement is averaged with the transmitter array .DELTA.t measurement to obtain a borehole compensated .DELTA.t measurement corresponding to each transmitter. When the borehole tool includes more than one transmitter, all the borehole compensated .DELTA.t measurements corresponding to each transmitter are averaged to obtain a comprehensive borehole compensated .DELTA.t measurement.

Abstract: The water treatment apparatus utilizes membrane separation technology to separate clean product from a contaminated water source. An improved valve (62, 64, 514) comprising a hollow cylindrical member (66, 84, 560), a valve member (68, 92, 566) slidably arranged within the hollow cylindrical member (66, 84, 560), and an interior channel (74, 86, 564) extending along at least a portion of the cylindrical member is provided. The improved valve (68, 64, 514) is arranged to provide a number of positions including a closed position, flush position and processing positions. These positions are arranged by axial movement of a valve member (68, 92, 566) along the cylindrical bore (74, 86, 564) of the valve body (66, 84, 560). A high pressure seal (310) is provided for use with submersible electric pumps (270) employed in the water treatment apparatus. The high pressure seal (310) provides a means for closing an opening (314) in a wall (316) of a housing containing high pressure water and for sealing around wires (318) extending through the opening (314). This seal (310) may also be used with any other technical device used under similar conditions. A tank (510) for use with smaller water treatment apparatus is also provided. This tank (510) is basically cylindrical with two part cylindrical recesses (532, 533) parallel to the axis of the tank (510) and lying along one side of the tank. Each recess (532, 533) receives a respective one of the cylindrical pump body (513) and the cylindrical reactor body (515). The pump (513) and reactor (515) are therefore efficiently stored within the cylindrical surface of the main tank (510).

Title: Method for purifying adipic acid by crystallization
Inventor: PATOIS CARL
IPC: C07C55/14
Filed: 1997-05-29
Abstract: The invention discloses a method for purifying adipic acid by crystallization or recrystallization in at least one carbolyxic acid. More precisely, it discloses an improvement in adipic acid crystallization or recrystallization, characterised in that the said crystallization or recrystallization is effected in at least one carboxylic acid with a melting point below 20 ·C. The presence of carbon monoxide during crystallization or recrystallization can have a favourable effect on the adipic acid purity, in particular by reducing the content of metal catalyst traces of the adipic acid. The adipic acid purity can also be improved when the crystallization or recrystallization is effected in presence of a strong proton acid.
