Patent CA-2153055-A1 (CA)
Title: Vessel mooring system
Inventor: KORSGAARD JENS
IPC: B63B21/00
Filed: 1993-12-29
Abstract: A vessel (11) with a mooring recess (15) on the bottom of the hull moors to a submerged buoyant mooring element (12) anchored to the ocean bottom by hoisting the mooring element (12) from a stowed position at a depth of net neutral buoyancy of the mooring element and its anchoring system (18) into contact with the mooring recess (15). The mooring operation is completed safely, quickly, and positively by rapidly withdrawing seawater into the hull (16) through an opening (58) in the mooring recess so as to reduce the hydrostatic pressure acting on the top of the mooring element as the element comes into contact with the hull of the vessel. The pressure reduction is sufficient to shift the mooring element and its anchoring system from a net negative to a net positive buoyancy condition at the keel depth of the vessel. The seawater may be withdrawn by a high capacity pump (56) that is either specifically installed for this purpose or is part of a bow thruster system of a type commonly found on large vessels.

A capstan (46) is connected to an operating shaft (443, as is a coupling member (64).  Rotation of the capstan by yard personnel effects movement of the gate between its open and closed positions.  A blocking bar (62) is engaged by the coupling member to lock the gate in its closed position.  A lost motion connection between the pinion and the coupling member enables the gate to be unlocked prior to movement of the rack by the pinion, and locked in its closed position subsequent to movement thereto by the rack and pinion.          The arrangement produces a desired sequence of gate operations (unlocking, opening, closing, relocking) which occur automatically.
Patent CA-2158721-A1 (CA)
Title: Method and apparatus for storing and mixing a plurality of fluids and body fluid sampling cartridge using same
Inventor: MACEMON JAMES H
IPC: B01L9/06
Filed: 1995-09-20
Abstract: A mixing device includes a plurality of elongated ampules mounted on a rotatable support with the longitudinal axis of each ampule inclined inwardly toward the rotational axis of the rotatable support. When the mixing device rotates about the rotational support, centrifugal force causes fluid in each ampule to move toward the end farthest away from the rotatable support. A bubble in each ampulethen moves toward the opposite end. In one embodiment, the rotational support isinclined so that the end of each ampule positioned farthest from the rotational support is positioned sufficiently above the other end so that the bubble rises to the end farther from the support in at least one position as the support rotates. As a result, a bubble in each ampule moves back and forth between the ends of the ampule as the rotatable support rotates to mix respective fluids in the ampules. In another embodiment, the ampules are pivotably mounted on the elongated support so that opposite ends are alternately positioned farthest from the support, thereby causing a bubble to move back and forth in each ampule. A chamber for collectinga blood sampling may be positioned on the rotatable support for subsequent analysis by an analysis machine that uses the fluids in the ampules for calibrating and washing purposes.

Title: Automating production and processing of financial documents
Inventor: MESSENGER STEVEN
IPC: H04M11/06
Filed: 1995-12-14
Abstract: A financial instrument such as check contains a transaction record in human-readable form which is digitally signed, error checking characters corresponding to the characters of the transaction record, and error recovery characters corresponding to both the record characters and the error checking characters. An image of the financial instrument is delivered by facsimile transmission to a service center for depositing, certification, authentication or registration. The image is subjected to optical character recognition, and an error calculation is performed using the error checking characters to detect recognition errors. In response to a recognition error, the error recovery characters are used to reconstruct the instrument data.  The various characters in the instrument are arranged in error-handling coding blocks whose members are distributed to accommodate common problems associated with facsimile transmission and poor paper handling practices.  Authentication involves verification of the digital signature  to verify the source of the instrument and absence of alterations.  To allow detection of digital impersonation, all financial instruments from a particular source contain transaction codes that reflect the issuing sequence of the instruments and contain random elements that cannot be predicted.

Patent CA-2169701-A1 (CA)
Title: Electrostatic rotary atomizing spray device
Inventor: DAVIS DENNIS
IPC: B05B3/10
Filed: 1996-02-16
Abstract: A rotary atomizer has an internal power supply in the atomizer housing about which is passed cooling air.          The air then flows out of the atomizer housing in a twisting direction as vectored air in the same direction of rotation as the atomizer head to eliminate any vacuum condition around the atomizer head and to provide shaping control of the coating being sprayed.  Exhaust air from an air turbine motor driving the atomizer head is directed around the outside surface of the atomizer housing to prevent the liquid coating from wrapping back and accumulating onto the atomizer housing.  A speed sensing system is mounted in the atomizer housing and utilizes both magnetics and optics for accurately measuring the rotational speed of the air turbine motor in the presence of high electrostatic charge and RF fields from the internal power supply.  The power supply is disposed within the atomizer housing about the turbine motor.  The atomizing head, in one embodiment, incorporates an insert which divides the flow of coating material into a plurality of individual streams to improve the atomization of the coating material from the atomizing head.  In another embodiment, an insert is located in the atomizing head to insure that the front flow surface of the atomizer head remains wet during operation so that the atomizing head is easier to clean.          The power supply is ring shaped and encircles the turbine and the paint flow passage through the turbine.  An intrinsic safety barrier is provided to supply electrical power to the power supply.  The intrinsic safety barrier is incorporated into the feedback loop of a voltage regulator.
