摘要:
A method of and apparatus for the simultaneous transmission of voice and data information over the same PCM transmission channel. During periods when only voice information is to be transmitted, the analog voice information is sampled at a first sampling rate, thus providing a digitized voice rate equal to the transmission rate capability of the transmission channel. During periods when both voice and data are to be transmitted, the analog voice information is sampled at a second sampling rate less than the first sampling rate, thus allowing the merged voice and data information to have a total digitized transmission rate equal to the transmission rate capability of the transmission channel.

To uniformly and economically disperse liquids, in the form of sprays of droplets, on surfaces of particles, the particles are lifted in a hollow drum by rotation of the drum about a near horizontal axis. Inside the drum, cantilevered non-rotating shafts position one or more powered slightly conical discs selectively tiltable to disperse sprays of droplets from a central area, in which particles are lifted while centrifugally held to the drum wall and then fall freely back to the wall to start another cycle. The cycles continue until the particles have a desired quantity of liquid on all their surfaces, when the particles leave the drum at an end opposite their entry end. Wood particles can be treated with liquid resin binders, and/or wax emulsions and subsequently formed into boards.

In a two-door road vehicle with rear seats, the seat belt associated with each front seat has its lower outboard end connected to the vehicle body by means of an elongate member (2) along which the belt end can slide forwardly for use and rearwardly when out of use to clearthe door aperture under the pull of a retractor spring, the elongate member (2) extending to a free end from a bolt connection into a tapped anchorage socket, associated with an anti-rotation fastening comprising a pin received in a plain hole or a self tapping screw connection.

A liquid is supplied to a vessel (10) to form a pool (21) from which it discharges through a venturi. A supply pipe or pipes (12, 30) convey other liquids and/or gases from separate sources or from above the liquid pool into the venturi for mixing with the liquid. The supply pipes can extend through the pool and be perforated (22) to tend to maintain the level of the pool. Associated with the venturi are pressure sensors (40, 41) for measuring flow and a densiometer (52) permitting mass flow rate measurement of gas and liquid phases. The apparatus can be incorporated in a cartridge (60) for reception in a receptacle (61) at a subsea installation.

A buoy for use in loading or unloading of a flowable medium, especially oil, the buoy (2) at its lower end being arranged for connection to at least one transfer line (6) and further being arranged to be introduced into a submerged downwardly open receiving space in a floating vessel (1), and the buoy (2) in operation forming a transfer connection between the transfer line (6) and a tube system (41) on the vessel. The buoy (2) comprises an outer buoyancy member (30) arranged for releasable locking to the receiving space (3) of the vessel (1) by means of a locking mechanism (56, 57) arranged therein, and centrally in the outer member (30) a rotatably mounted member (31) which forms a passage (32) for medium and at its ends is arranged for connection to the transfer line (6) and the tube system (41) on the vessel (1), respectively. The buoy (2) at its upper end is connected to a means for hoisting and introducing the buoy into the receiving space (3) of the vessel (1).
摘要:
Large scale integrated circuits are fabricated using redundant circuit elements to replace defective circuit elements by discretionary interconnect changes as determined by fine-grain testing of the integrated circuits after the logic units (such as individual transistors or logic gates) are fabricated and before they are electrically interconnected. The redundant circuit elements are then interconnected to non-defective circuit elements by one of two methods. In the first method a stepper-scanner apparatus modified to expose most of a resist layer defines the interconnect circuitry, but is shuttered-off over the discretionary interconnect changes. Then the discretionary interconnect changes are exposed by a conventional direct write on wafer pattern generation apparatus. In the second method, the interconnect patterning is accomplished by first fabricating a fixed custom mask defining the interconnect layer for a particular lot size (such as 100) of wafers. The fixed mask is fabricated after each wafer of the lot has been tested, and incorporates all the discretionary changes required to avoid interconnection to each defective circuit element in each of the wafers. The fixed custom mask is then used to expose the resist layer defining the interconnect circuitry for each of the 100 wafers.

An arrangement in a vessel for loading or unloading of a flowable medium, especially oil, the vessel (1) being provided with a submerged downwardly open receiving space (3) for receiving and securing a submarine buoy (2) which is anchored to the sea bed (4) and is coupled to at least one transfer line (6) for medium. The receiving space (3) is arranged at a submerged location at the outer side of the hull of the vessel and has an at least partly downwards essentially conically enlarged shape, for mating with a buoy (2) of a corresponding outer shape. In connection with the receiving space (3) there is provided a service shaft (9) connecting the receiving space (3) with the deck (8) of the vessel. The receiving space (3) preferably is formed from a module built into the bow portion of the vessel (1).
