Patent CA-2308667-A1 (CA)
Inventor: BAKKE STIG
IPC: E21B23/04
Filed: 2000-05-17
Abstract: A hydraulically releasable coupling device has an upstream part arranged to permit connection to tubing and a downstream part arranged to be connected to a tool or equipment. A radially expandable locking ring is configured to expand and thereby to disconnect the coupling device. A movable securing ring portion encloses the locking ring at least partially in an unexpanded locking position thereof. A piston body is connected to the securing ring portion and has a through passage which is provided downstream with a restriction element. The piston body has an upstream piston head with an annular upstream reaction surface and an annular downstream reaction surface for pressure fluid in counterflow. The piston head has a larger diameter than a downstream extension formed as a piston skirt, in which the restriction element is mounted. A longitudinal portion of the piston skirt, next to the piston head, is enclosed by a cylinder chamber of the piston head accommodating a return spring.

Title: System and method for automatic notification of upcoming delivery of a mail item
Inventor: PINTSOV LEON A
IPC: G07B17/00
Filed: 2000-06-23
Abstract: In accordance with the present invention, when a mailer generates a mail piece, for example using mail generation software in a PC metering system, the mail generation software accesses a database of mailing addresses. This database also contains e-mail address of recipients in the mailing list (address database). If a mailer wants to send advance notice to a recipient that a mailpiece has been sent to the recipient, the mailer can choose this option automatically and use a unique mailpiece ID as an identifier of the upcoming mailpiece. (The mailpiece ID can be generated specially for this purpose and serve as a reference point for the mailer and the recipient). This can be particularly advantageous in a legal environment, when there is a need for timely distribution of information as well as the need for distribution of legally valid hard copy documents. The unique ID number may be printed in plain text in the address block and cryptographically encoded within the DPM. This ID number can be used to provide references and links to other relevant documents as well. When the DPM is scanned upon induction into a postal distribution network, system includes recognition of the recipient's e-mail address and automatically sends notice of intended delivery to the recipient. The notice may also include an estimated date of delivery.

Abstract: A continuous Liquid-Solids Circulating Fluidized Bed (LSCFB) preferably for use as an ion exchanger consists of two fluidized bed columns, a fluidized bed adsorber (downer) operating in conventional fluidized bed mode for adsorption of ions of interest and a fluidized bed riser for desorption of ions (operating as a riser fluidized bed) to provide regenerated particles. Ion exchange particles circulate continuously between the riser and the downer i.e. the particles that have adsorbed ions in the absorber pass from the adsorber (downer) to the desorber where they are regenerated and the so regenerated particles are return to the adsorber near the top of the adsorber column. The LSCFB can be used in processes for continuous recovery of the ions of interest.

Title: Alphanumeric message composing method using telephone keypad
Inventor: SCHWENDEMAN ROBERT J
IPC: H04Q7/16
Filed: 1999-04-07
Abstract: An interactive method for composing an alphanumeric message by a caller using a telephone keypad includes storing (215) a lexical database (135) from which a plurality of words can be recovered; storing a received sequence of key codes (405) representing a sequence in which keys on a telephone style keypad are keyed; and generating a word trellis including candidate words (415) derived from the sequence and the lexical database. In one aspect of the method, a most likely phrase (420) is formed from a trellis of the candidate words using conditional probabilities stored in the lexical database. In another aspect, keypad error correction is performed when a candidate word is not found in the lexical database. In another aspect, caller responses are used to determine a correct word when all candidate words of a subset of candidate words are incorrect.

Title: Cartridge paint-charging method and device therefor
Inventor: HOSODA TOSHIO
IPC: B05D3/00
Filed: 2000-04-25
Abstract: A paint-charging device for charging a cartridge (25) with paint to allow the paint to breathe during standby. The device comprises a charging valve (61) for feeding/discharging paint fed to the paint storage chamber (30) of the cartridge (25) attached to a charging block (52), and a paint breath valve (91) for feeding/discharging push-out thinner to/from a thinner storage chamber (31). The charging valve (61) is switched to the discharge side to feed the push-out thinner from the paint breath valve (91), thereby pushing out the paint in the paint storage chamber (30).     Further, the charging valve (61) is switched to the feed side to discharge the push-out thinner from the paint breath valve (91), thereby feeding the pain to the paint storage chamber (30). This allows the paint in the cartridge (25) to perform a breathing action, preventing separation of the pigment in the paint.
