摘要： A monolithic low noise variable gain amplifier with series feedback includes a dual gate field effect transistor (DGFET) having a common source FET and a common gate FET with scaled gate widths and/or an interelectrode matching element connected to ground through a capacitor positioned between the two gates for reducing the minimum noise figure of the common gate FET and establishing the output load for the common source FET, and an inductive series feedback line for connecting the common source FET to ground. The amount of series feedback between the source and ground of the DGFET as well as the appropriate output load obtained through gate width scaling are selected to make the conjugate input impedance equal to the optimum impedance for a simultaneous noise match and power match.

摘要： This invention provides a switched limiter with variable attenuation designed with monolithic GaAs p-i-n diodes. Greater than 30 dB of small-signal variable attenuation is achieved at X band frequencies, with a minimum insertion loss of 0.5 dB. The variable attenuation switched limiter provides 15 dB of isolation to a +30 dBm input signal. Under bias conditions that result in variable attenuation the variable attenuation switched limiter input impedance remains matched. When used as a passive limiter, 7 dB of limiting has been achieved for a +30 dBm input signal at 10 GHz.

摘要： A monolithic amplifier having a common-gate input stage with a device transconductance which is higher than required for input match, and a load impedance presented to the common-gate stage which is not conjugate matched. The present invention teaches a common-gate configuration using an FET with higher transconductance and a higher output load impedance. Over narrower bandwidths, excellent input match is thus obtained with noise figures at least as good as those obtained with the common-source approach. This combination of noise figure and input match is achieved in a compact monolithic structure.

摘要： A transportation method and barge-carrying water-borne vessel therefor having a hull with rigid supporting and hull-reinforcing structure, a bow, a stern, and side walls providing a series of buoyancy compartments. The hull has a hollow interior defining at least one hold extending most of the length of said vessel. The bottom of the hold is always below the level of the sea. Water can be placed from the sea into the hold and can be pumped out from it. A gate at one end of the vessel is opened for flotation loading of the hold, when the hold is partially flooded, with buoyant cargo carriers such as barges, lighters and pontoons. Each such carrier may be held down against the bottom of the hold. A collision bulkhead located adjacent the gate enables closing the hold off in a watertight manner, and this collision bulkhead can be opened to enable the flotation loading and unloading.

摘要： An improvement in a barge-carrying flotation-loaded waterborne vessel. A hollow interior defines upper and lower longitudinal barge holds arranged in vertical rows of aligned tiers, each hold being flooded during the time it is loaded and unloaded. There is at least one loading lock at one end of the vessel for enabling flotation loading of each vertical row of barge holds; each lock has a pair of side bulkheads and a bottom, and gate means for separating the lock from and opening it to the outside for flotation loading and unloading of one barge at a time. There is also a separate lock gate for each tier of each row for connecting a hold of each row to a lock. In each lock there are sets of barge support panels, each pivotally attached by a horizontal longitudinally extending pivot to one of the side bulkheads, at least one set being disposed on each side of the lock adjacent to and approximately on a level with each upper longitudinal barge hold. Associated with each set of barge support panels is an erection system for swinging panels up from a vertical storage position to a horizontal barge-supporting position. First locking and releasing means secure each panel in its vertical storage position and release each panel for movement to its load-supporting position. Second locking and releasing means secure each panel in its horizontal barge-supporting position and release each panel to return to its vertical storage position.

摘要： A barge-carrying vessel of the flotation loading and unloading type. Each barge-stowage hold has parallel, vertical side walls that are only slightly further apart from each other than the width of the barges to be stowed. The barges are held down against the bottom of the hold, enabling transfer of buoyancy from the barges to the vessel when the hold is flooded. For this purpose, a series of guides is secured to one side wall of the hold, each guide comprising a pair of parallel vertical tracks. In between each pair of tracks is a wedge having a sloping outer face for engagement with a barge in a wedging manner to force this barge against the opposite side wall. The wedges are raised and lowered as needed, and are positively secured in place in their barge-hold down position.

摘要： A vessel for transporting, on a body of water, cargo consisting of barges, pontoons, and lighters, and other floating cargoes. The hull has a bow, a stern, and water-tight buoyancy compartments in side walls. The hull also has a perforate bottom shell with rigid supporting and reinforcing structure, enabling the cargo hold to be flooded and open to the sea under all conditions while loading, in transit, and during discharge. A hinged gate is provided at either or both ends of the hull for rapid flotation loading and unloading of the floating cargo, and each gate closed during transportation of the cargo. The vessel carries means for moving the cargo into, out of, and within the hold. A series of vertical pistons secure the floating cargo units by exerting a downward force to bring the cargo to bear on the hull structure. The water in the hold, having communication with the sea, provides buoyancy for the cargoes secured therein. This buoyancy supports most of the deadweight of floating cargoes, so that typically only a minor portion of the deadweight is carried by the vessel. In the case where the buoyancy of some cargo unit in the secured position exceeds its weight, such as in a lightly loaded barge, a transfer of buoyancy to the vessel assists the vessel in supporting the heavier floating cargo units. Thus such buoyancy and the transfer of buoyancy by floating cargo units to support the cargo's own weight reduces the load carried by the vessel, enabling a structural saving in its weight; this, together with rapid loading and unloading, provide a more efficient transportation system.

摘要： A transportation method and a barge-carrying waterborne vessel in which there is flotation loading and unloading, with the loading being assisted by water flow from the gate into the flooded vessel and toward the opposite end of the vessel from the gate. For unloading, the water flows in the opposite direction, toward the gate. Preferably, loading is through a gate in the stern while water is being pumped out from a sump at the forward end of a hold. When barges are fully loaded into the hold, the stern gate is closed and the hold may be dried out; then the barges are secured in place against movement relative to the vessel. There may be more than one hold having at least one longitudinal bulkhead dividing the holds. There may be either a separate gate for each hold or a transfer system in which each longitudinal bulkhead has an archway providing a passageway joining adjacent holds. During lateral transfer water jets may play against the sides of the barge to cause lateral movement. Adjacent the gate there are preferably rollers, some of which are powered, which engage the sides of each barge and move it into or out from the gate and the hold. Novel barge retention systems are provided requiring relatively few, if any, powered devices.
