Patent CA-2028102-C (CA)
Title: Undersea package and installation system
Inventor: MOHN FRANK
IPC: E21B33/038
Filed: 1990-02-23
Granted: 1997-07-22
Abstract: An operational package comprising either a pump/driver package (1; 100) or a valve package (250) is retrievably installed at a subsea station by a receptacle (10, 110, 251). Co-operating connection means on the package and the receptacle establish fluid and/or electrical connection between the package and the receptacle on reception or the package within the receptacle. Seal means (14) carried by the package are moved into a condition to seal any such fluid connections. Installation is effected by establishing a running loop extending from a surface vessel downwardly through the receptacle (10; 110) and upwardly to the surface vessel outside the receptacle, the package (1; 100) being moved on and guided by the wire loop from the surface vessel into the receptacle. Alternatively, a handling tool (120) is employed with co-operating releasable connecting means (151) on the handling tool and the receptacle, and operating means (124, 125) operable between the handling tool and the package to effect movement of the package inwardly of the receptacle, after connection of the connecting means.

Title: Radio receiver operational checking method and system
Inventor: KOENIG ROBERT H
IPC: H04B17/20
Filed: 1991-02-21
Granted: 1999-02-16
Abstract: A clock-driven pulse source is used to apply repetitive short pulses to the squelch control connection point of the squelch circuitry of a radio receiver to deactivate momentarily the squelch circuitry at regular intervals. This provides periodic noise bursts of "de-squelch" pulses on an otherwise silent radio in order to inform the radio operator that the radio is live and that the volume is adequate. A light may also be connected to the system to provide a second, visual, indicator of the operational status of the radio.    This radio receiver operational checking system may also be utilized where there are two or more radios in use by providing an additional clock-driven pulse source for each radio in use. The system may be arranged so that the status of individual radios may be quickly ascertained by sound and/or by light indicators.

Title: Chimeric dna-rna catalytic sequences
Inventor: ROSSI JOHN J
IPC: A61K38/00
Filed: 1990-06-05
Granted: 2003-02-25
Abstract: This invention provides chimeric DNA/RNA catalytic molecules useful to cleave RNA sequences. The invention specif-cally provides two different chimeric DNA-RNA-DNA-RNA-DNA catalytic molecules which are targeted to cleave HIV-1 RNA sequences. These chimeric molecules include DNA sequences which flank a catalytic RNA enter. Interaction with the HIV-1 substrate RNAs is achieved by Watson-Crick base pairing of the DNA  flanking sequences with HIV-I RNA. The catalytic ribonucleotide center cleaves the phosphodiester bond of the substrate HIV-I  RNA at the expected location.

Title: Semiconductor optical functional device
Inventor: ISHIKAWA TAKUYA
IPC: G02B6/12
Filed: 1991-07-09
Granted: 2001-09-25
Abstract: Provided as an optical functional device which comprises a substrate, a lower cladding layer, a waveguide layer, and an upper cladding layer each formed of a semiconductor, and in which at least one of the three layers except the substrate has a quantum well structure at a quantum confined potential. The well plane of the quantum well structure is symmetrical with respect to the center position thereof, and varies in proportion to the square of the distance from the center position.        If an electric field is applied perpendicular to the well plane , the respective changes in the absorption coefficient and refractive index in the vicinity of the absorption edge are influenced by absorption peak shifts attributable to both 1e-1hh and 1e-11h transitions. Thus, the optical functional device operates in response to both TE and TM mode light without depending on polarization.

Title: Method and apparatus for preparing validated mail tray labels
Inventor: SANSONE RONALD P
IPC: G07B17/00
Filed: 1991-10-07
Granted: 1995-12-12
Abstract: A method and system for providing validated labels that are attached to mail trays immediately upon mail being processed by a mailer and placed in a tray.  Mail lists and programs for sanitizing the mail list and sorting the mail to achieve postal discounts are stored in a mailer's processor.  A printer is controlled to print addresses on documents, such as letters, that are forwarded to an inserter.  A mail list stored in the processor indicates where the mail is to be sent, the class of mail, level of sortation and the contents of the mail.  Tray contents are computed and appropriate labels are prepared by a label printer under its control.  By making the tray label printing an intricate part of the mail processing system, as opposed to being an adjunct to it, the providing of the labels becomes more efficient, reliable and economical.

The addition of pollucite to the leucite article provides a ceramic article whose thermal expansion coefficient can be varied from 2 x 10-6 to 27 x 10-6°C-1 as measured over the range 50°-700°C.      This invention also relates to this leucite/pollucite ceramic article.

Title: Improved print quality laser marker
Inventor: STONE J JAMES
IPC: B23K26/06
Filed: 1992-10-07
Granted: 1999-12-21
Abstract: Laser marker apparatus for marking indicia onto a substrate includes an exit lens having a focal length, a plurality of lasers, a plurality of turning mirrors, and at least one directing mirror. The surface of the substrate to be marked is positioned generally at the focal plane of the lens. The plurality of lasers is arranged so that their energy output beams are oriented in a generally parallel relationship. The plurality of turning mirrors are positioned along the beam path of each respective laser and are oriented to reflect the output beams at predetermined angles. The directing mirrors redirect the output beams to form a column of spaced apart spots on the substrate.      One of the directing mirrors is then moved in a first direction so as to form another column of spots on the substrate. Movement in another direction forms a third column of spots on the substrate. The columns are interleaved to create a composite column of higher resolution for marking Alpha-numeric characters.

IPC: G06F11/14

Granted: 2000-01-18
Abstract: Techniques for fault-tolerant computing without fault-tolerant hardware or operating systems. The techniques employ a monitor daemon which is implemented as one or more user processes and a fault-tolerant library which can be bound into application programs. A user process is made fault tolerant by registering it with the monitor daemon. The degree of fault tolerance can be controlled by means of the fault-tolerant library. Included in the fault-tolerant library are functions which define portions of a user process's memory as critical memory, which copy the critical memory to persistent storage, and which restore the critical memory from persistent storage. The monitor daemon monitors fault-tolerant processes, and when such a process hangs or crashes, the daemon restarts it. When the techniques are employed in a mufti-node system, the monitor on each node monitors one other node in addition to the processes in its own node. In addition, the monitor may maintain copies of the state of fault- tolerant processes running at least on the monitored node. When the monitored node fails, the monitor starts the processes from the monitored node for which the monitor has state on its own node. When a node leaves or rejoins the system, the relationship between monitored and monitoring nodes is automatically reconfigured.
