Patent CA-2266078-C (CA)
Inventor: YAMAGUCHI MITSUO
IPC: A23G3/02
Filed: 1997-07-18
Granted: 2005-03-15
Abstract: There are provided a method of producing a pressurized gas-entrapping candy and a pressurized gas-entrapping apparatus to be used for the method. According to the method, the pressurized gas-entrapping candy is produced by preparing a hard candy with a conventional method, crushing the hard candy and sieving to obtain candy particles, attaching a pipe with fine holes in its peripheral wall to a cylindrical vessel through an opening formed in a lid of the cylindrical vessel, filling the candy particles in a space between the cylindrical vessel and the pipe, loading the cylindrical vessel in a long and cylindrical pressure-resistant vessel, feeding heating steam and then cooling water to a jacket portion of the pressure-resistant vessel, while maintaining pressurized state in the pressure-resistant vessel, to carry out heating and cooling treatments of the candy particles in the cylindrical vessel, and then releasing the pressurized state of the pressure-resistant vessel. Since the candy particles do not directly contact with jacket portion of the pressure-resistant vessel, therefore, thermal change in quality does not occur and since the cylindrical vessel fills a function as a cartridge, the pressurized gas-entrapping candy can be produced in substantially continuous manner and in large amount to decrease production cost thereof.

Title: Zoned pressure screen
Inventor: PIMLEY JOHN J
IPC: B01D33/06

Granted: 2007-03-13
Abstract: A pressure screen (10) for screening a suspension of papermaking stock employs a cylindrical screen means (20) which comprises a single screen or a plurality of axially aligned screens and in which the stock screening regions are arranged in annular zones (22a, 22b, 22c) with a rejects region (24a, 24b) located between the screening zones. The intermediate rejects regions shorten the distance which contaminants must move across the inlet surface of the screen and reduce the buildup of concentration of rejects on the screen surface, thereby optimizing the performance of the screen.

Abstract: One or more inflatable tubes are used to support a self-erecting tent. If two or more tubes then they may have at least one cross over criss-crossed in the manner of conventional domed tent poles. The tube or tubes are secured or releasable secured to the tent so that the tent is self-erecting as the tube or tubes are inflated. When two or more tubes are employed, the tubes may be connected by an auxiliary tube so that forcing pressurized air into one tube results in all tubes inflating simultaneously. The ends of the tubes are self-sealing so as to accommodate relatively high air pressure within the tube, in the order of 20-30 pounds per square inch inflated pressure, thereby providing a significantly rigid structure from which the tent is suspended.

Abstract: An on-machine-seamable multi-axial press fabric for the press section of a paper machine is made from a base fabric layer assembled by spirally winding a fabric strip in a plurality of contiguous turns, each of which abuts against and is attached to those adjacent thereto.      The endless base fabric layer is flattened to produce first and second fabric plies joined to one another at folds. Crosswise yarns are removed from each turn of the fabric strip at the folds to produce unbound sections of lengthwise yarns. A base fabric, having seaming loops along its widthwise edges, is disposed between the first and second fabric plies. The seaming loops extend outwardly between the unbound sections of the lengthwise yarns from between the first and second fabric plies.      The first and second fabric plies and the base fabric are laminated to one another by needling staple fiber batt material therethrough.

Patent CA-2284418-C (CA)
Inventor: MACBETH BRUCE F
IPC: H02H3/44
Filed: 1999-09-30
Granted: 2002-04-09
Abstract: Arcing faults are detected by sensing a voltage signal proportional to the rate of change, or di/dt, of the line current when the current steps into an arc fault. A current transformer is used to create the di/dt signal.  The transformer has a selected core type, number of windings, and size which saturates at a pre determined level of primary current. The saturation acts to clamp the maximum di/dt voltage signal at the transformer output, and produce a constant output voltage. The constant output voltage eliminates a signal with a high di/dt, which may occur during a lamp burnout, from producing a much larger di/dt signal than that caused by an arc fault at a lower level of step current. The di/dt signal is passed through a high pass filter, which attenuates 60hz sinusoidal signals, after which the signal is integrated. The integrator acts to delay circuit interruption means until a predetermined number of arcs has occurred. When the integrator voltage reaches a predetermined voltage level, a trigger device activates an electronic switch, which in turn activates circuit interrupting means. One of the novel aspects of this invention is the elimination of the need for a DC power supply.

Abstract: A steam-assisted gravity drainage process, involving a co-operating pair of closely spaced, horizontal steam injection and liquid production wells, is modified as follows: .cndot. during the initial circulation phase, the tubing string is landed at the toe of the injection well; and .cndot. during the following injection phase, the tubing string is landed at the heel or intermediate the heel and toe. It has been found that steam preferentially leaks into the reservoir at heel and toe due to pressure drop arising from friction effects through the annulus, between the tubing string and screened liner. So the steam delivery point through the tubing string during the circulation phase is located at the toe, but it is retracted to the heel or to between heel and toe for the injection phase, to shorten the annulus and thereby lessen the pressure drop.

Title: Method for creating a digital data stream
Inventor: PAWSON DAVE
IPC: H04N19/61
Filed: 1996-07-12
Granted: 2002-05-14
Abstract: A method and apparatus for use in a digital video delivery system is provided. A digital representation of an audio-visual work, such as an MPEG file, is parsed to produce a tag file. The tag file includes information about each of the frames in the audio-visual work. During the performance of the audio-visual work, data from the digital representation is sent from a video pump to a decoder. Seek operations are performed by causing the video pump to stop transmitting data from the current position in the digital representation, and to start transmitting data from a new position in the digital representation. The information in the tag file is inspected to determine the new position from which to start transmitting data. To ensure that the data stream transmitted by the video pump maintains compliance with the applicable video format, prefix data that includes appropriate header information is transmitted by said video pump prior to transmitting data from the new position. Fast and slow forward and rewind operations are performed by selecting video frames based on the information contained in the tag file and the desired presentation rate, and generating a data stream containing data that represents the selected video frames. A video editor is provided for generating a new video file from pre-existing video files. The video editor selects frames from the pre-existing video files based on editing commands and the information contained in the tag files of the pre-existing video files. A presentation rate, start position, end position, and source file may be separately specified for each sequence to be created by the video editor.
