Title: Dual compression format digital video production system
Inventor: WASHINO KINYA
IPC: H04N7/15
Filed: 1996-03-01
Abstract: An audio/video production system (16) is implemented on a PC-based platform, preferably utilizing various forms of removable magnetic, optical, or magneto-optical storage media (70). Specially modified cameras or other sources provide digitally data-compressed audio and video programm materials in two formats, a first format having a higher data-compression ratio and intended for use in off-line systems to develop edit decision lists, and a second format having a lower data-compression ratio and intended for use in on--line editing and to produce the final representations of the programs. Off-line editing decisions may thus be developed on a PC (102) using removable storage media (104), and final representations of the programs may be produced on-line in accordance with stationary-head or rotary-head digital-tape--based formats, such as DAT, 6-mm or 8-mm tapes. In an alternative embodiment, automatic and unattended editing, or extended program playback of more than 40 hours duration of digital video, is available.

Title: A method of producing gas hydrate
Inventor: WILLIAMS ANDREW RICHARD
IPC: B01F3/04
Filed: 1997-01-07
Abstract: A plant for producing natural gas hydrate comprises three stages (i), (ii) and (iii). Stage (i) comprises three pressure vessels (A1, A2 and A3), stage (ii) two pressure vessels (A4 and A5), and stage (iii) the pressure vessel (A6). The conditions of temperature and pressure in the pressure vessels are such that the gas hydrate is formed in the vessels. The formed hydrate is taken off through pipes (e1, e2, e3, e4, e5 and e6) from the pressure vessels to a manifold (34). Chilled water which is both the reactant water and coolant for the process is provided by cooling means (20) and supplied simultaneously to the lower part of each pressure vessel via pipe (22), manifold (24) and pipes (b1, b2, b3, b4, b5 and b6). Natural gas from supply (26) is fed via pipe (30), manifold (32) and pipes (c1, c2 and c3) to nozzles in the lower part of each vessel (A1, A2 and A3) from which nozzles the gas bubbles upwards through the columns of water in vessels (A1, A2 and A3). Unreacted gas is fed from vessels (A1, A2 and A3) to similar nozzles in the vessels (A4 and A5) from which unreacted gas is fed to a nozzle in the vessel (A6) from which the unreacted gas is taken off through pipe (d6). The mean upward superficial velocity of the gas is substantially the same in all three stages.

Inventor: HELD WERNER
IPC: B64C21/08
Filed: 1997-10-20
Abstract: The boundary layer flow along the surface of an aircraft rudder assembly is controlled by suction applied through perforations primarily installed in the leading edge of the rudder assembly.      The control is such that a laminar flow is enforced or at least such that any turbulent flow is displaced so that it begins downstream of the rudder assembly leading edge. Suction air chambers are arranged along the leading edge inside a nose box of the rudder assembly and these boxes are connected through air ducts and a valve system to an exhaust fan. The valve system and the exhaust fan are controlled by a central processing unit providing a flow controller for the suction in response to control signals produced from rated values and sensed actual valves to provide a uniform distribution of the suction along the leading edge of the rudder assembly. The suction system may be switched over to a de-icing mode by blowing warm air out through the perforations in a controlled manner.

Inventor: IWINSKI DEAN J
IPC: B25D15/02
Filed: 1997-10-30
Abstract: A reversible rotary wrench includes an impact mechanism for applying intermittent torque impulses to a load.  The mechanism includes a rotatable shaft having an axis and adapted to be coupled to a motive source, a rotatable anvil for coupling to the load and having a pair of anvil ears, a tubular hammer substantially coaxial with the shaft and having a pair of hammer ears engageable with the anvil ears and a rotatable tubular drive coupling member substantially coaxial with the shaft.  The mechanism also includes a first helical cam structure coupling the drive coupling member to the shaft, a second helical cam structure coupling the drive coupling member to the hammer, and a spring biasing the hammer axially toward the anvil to engage the hammer ears with the anvil ears.  When the shaft is rotated in a first helical direction and torque exerted by the anvil on the hammer exceeds a given threshold, the sleeve rotates and the first cam structure responds to rotation of the shaft to move the hammer axially away from the anvil thereby disengaging the hammer from the anvil. When the shaft is rotated in a second direction and torque exerted by the anvil on the hammer exceeds a given threshold, the second cam structure responds to rotation of the shaft to move the hammer axially away from the anvil thereby disengaging the hammer from the anvil.

Patent CA-2237742-A1 (CA)
Inventor: CHEN SHAWFU
IPC: H04L12/24
Filed: 1998-05-14
Abstract: The present invention presents a new way of data transfer in a multi-host computer environment without causing unnecessary system idle time or other processing delays by utilizing an activate_on_receipt mechanism. This mechanism sets aside a temporary storage upon receiving certain commands such as a read which may tie-up system resources until the incoming data is received. The system environment then proceeds with performing other operations until the first bytes of incoming requested data is received at the temporary storage location, at which time the mechanism terminates all running operations in favor of processing the data that is being received. If the size of the requested temporary storage location is accommodating to the size of the incoming data, data is directly read. Otherwise a new storage location is obtained and the data copied and fully received at this new location before it is read.

Title: Cartridge-based drug delivery device
Inventor: TSALS IZRAIL
IPC: A61M5/158
Filed: 1996-12-11
Abstract: A liquid drug delivery device (40) is adapted to be adhered to the skin of a subject by a base member (49) defining a skin-contacting surface (50) having an adhesive coating. A columnar cartridge (48) serves as reservoir for the drug and is incorporated in a housing which is connected to the base member (49) such that in use the longitudinal axis of the cartridge (48) is disposed substantially parallel to the skin-contacting surface (50). A delivery needle communicating in use with the interior of the cartridge (48) penetrates the skin of the subject when the housing snaps downward relative to the base member (49). This action also causes the actuation of a citric acid (42)/sodium bicarbonate (43) gas generator which generates a gas to move a piston (41) within the cartridge (48), compressing the drug compartment. This compression causes a stopper to be penetrated by a conduit in communication with the delivery needle, allowing the drug to be ejected from the compartment through the needle and into the subcutaneous tissue of the subject.

Inventor: HAACK BRIAN
IPC: B60R13/01
Filed: 1998-06-04
Abstract: The present invention is a truck bed liner having two side walls, a front wall a bottom and a rear wall the bottom further having an integrated liner incorporated into it. The divider is formed by either molding or cutting slots on three sides of the liner bottom. The fourth side is molded or cut into a living hinge. The living hinge allows the unattached portion of the truck bed liner bottom to move freely about the hinge. The side walls of the truck bed liner include receiving channels into which the hinged dividers are locked into place. A latch is molded into and extends from the lower aspect of each sidewall at a point in which when the divider is placed into its horizontal position, will hold it in place. In operation an operator can position the hinged divider to a 90° position with respect to the bottom and lock it into the receiving channels found on the side walls. Once locked into position a compartment is created on each side of the raised wall. When compartmentalization is no longer needed, the hinged portion of the liner can be removed from the side wall channels and placed into a horizontal position, being locked into position by the latches.
