Abstract: A line blind valve is disclosed which includes a housing having opposed similar housing halves with resilient sleeve units which compressibly engage each other in the valve open condition and engage opposite sides of the gate or blind in the valve closed condition.  The line blind valve provides visibility of all gate edges so as to give a positive indication that the gate or blind has passed completely through the seals.  Lockout is also provided when the gate or blind is closed.  Each sleeve unit has a plurality of compression holes extending axially and arranged at intervals relative to the circumference of  the  sleeve.   An encircling stiffening ring of harder material is encapsulated in each sleeve so as to be positioned at the inner end of the compression holes.  The line blind valve construction of the present invention results in no leakage to the outside when the valve is fully open and no leakage to the outside or past the gate internally when the valve is fully closed.

Granted: 2003-03-11
Abstract: Anti-falsification paper characterized in that thin fragments having brightness, which are obtained by fragmenting nacreous pigment coated paper coated with a nacreous pigment coating solution mainly comprising a nacreous pigment and a binder insoluble in cold water but soluble in hot water, are allowed to exist near the surface of a substrate sheet. Even when falsification is attempted by reproduction using a color copying machine, the colors of the thin fragments having brightness, which are mixed in paper, cannot be reproduced. Therefore, a genuine (original) can be easily distinguished from a forgery (copy).      The thin fragments are firmly bonded to paper by the action of the binder, and fall-off of the thin fragments does not occur at the time of printing. Even when anti-falsification paper becomes spoilage or waste paper, thin fragment with brightness does not adversely affect recovery of the pulp.

Abstract: A vehicle communications network is provided which includes a ground translation circuit and interfacing transmitter circuits that achieve smooth current sourcing transitions. Included is a communications bus such as a J1850 having multiple-access for interfacing with a plurality of electronics, preferably within a vehicle. Each transceiver has a transmitter and receiver interfaced with the bus.

Abstract: An oil field Whip-Anchor System, for deviating a wellbore, which uses an improved whipstock (1) incorporating a new setting apparatus and method, attached to a mechanical (14M) or hydraulic anchor packer is disclosed. The complete Whip-Anchor System also includes an apparatus and method for retrieving the Whip-Anchor if it is used in wellbores which require retrievable wellbore deviation tools. The new apparatus reduces the number of whipstock bodies that must be warehoused to three fundamental types which fit all commonly used wellbores. The apparatus permits the proper "set" of a mechanical packer without fear of shearing the releasable attachment device currently used in the industry and permits an operator to "bottom hole wash" while setting a mechanical packer in a wellbore. The same apparatus and similar techniques are used for both mechanical or hydraulic packers. The system utilizes a slot cut in the face (11) of the whipstock for setting (13) and retrieval (12). Other improvements include a pinned spring loaded hinge assembly (6) which assures that the tip of the whipstock will fall against the wellbore, a deflector plate (7) that uses a surface hardening or polycrystalline diamond inserts to reduce wear on the top portion of the device during the window milling operation. Also disclosed are additional downhole tools for use with the Whip-Anchor System.

Abstract: A system for verifying that a card possessor is the authorized card owner compares scanned fingerprint data with fingerprint data encoded on an optical card.  More than one of the person's fingerprints are encoded on the card, and the process of identification of the card possessor involves the random selection of separate fingerprints for scanning and comparison against the encoded fingerprints.  A card reader/writer reads fingerprint characteristic information from an optical card inserted therein and a processing unit, connected to a fingerprint scanner and card reader/writer extracts from the scanned fingerprint certain well known indicators, and matches the recorded fingerprint characteristic data with the scanned fingerprint characteristics to establish identity therebetween.

Abstract: An aircraft inertial webbing reel is mounted in a housing and has a ratchet wheel.  A dog is mounted for spring-biased movement into engagement with the ratchet wheel teeth to lock the reel.  A spring-biased blocking cam normally blocks movement of the dog.  An inertia mass (96) movable within a chamber (94) has opposed end mounting surfaces (112, 130) with conical fittings (114, 132) which define an axis.  A linkage (100) comprising a pair of interconnected levers (102, 120) each having a distal end (106, 124) having a conical fitting (108, 126).  The fittings each confine a ball (118, 136) to mount the mass (96) on the lever distal ends (106, 124).  A sliding and pivotal fitting interconnects the lever proximal ends (138, 146) and provides an overcenter mechanism normally biasing the lever distal ends (106, 124) toward each other and against the mounting surfaces (112, 130) to clamp the balls (118, 136) within the conical fittings (108, 114, 132, 126).  A predetermined acceleration of the aircraft (90) in any direction causes the mass (96) to shift the balls (118, 136) and move the lever distal ends (106, 124) away from each other.  This moves an output member (152) which shifts the blocking cam to unblock the dog which locks the ratchet wheel, reel and webbing.  The housing (92) is mounted with the mass axis oriented laterally of the aircraft (90) so that the linkage (100) provides the same output in response to movement of the mass (96) laterally of the aircraft (90) along the axis or in any direction forwardly and vertically of the aircraft (90) in a plane perpendicular to the axis.  In another embodiment, the levers are connected by a link (38).

Abstract: In a network system for effecting signal transmission by plural channels, there are provided plural channel alteration units each of which is adapted to receive signals through plural channels and to output each of the signals entered by said plural channels in any of plural channels . Transmission control is executed in such a manner that mutually proximate plural signals, which have to be outputted by a designated same channel among the plural channels from a first one of the plural channel alteration units, are entered through respectively different channels into the first channel alteration unit. As the first channel alteration unit receives the plural signals by different channels, there can be resolved the drawback of a long waiting time for the output of the signals by a desired channel, encountered in case the signals are entered by a signal channel.
