Abstract: Techniques for initializing an arbitrary portion of memory with an arbitrary pattern includes using a memory controller for performing sequenced read and write operations. The memory controller receives address data, length data and pattern data on a data bus connected to a processor. The address data indicates a location in memory. The length data indicates an amount of memory to be initialized. The pattern data indicates a particular series of bits that is much shorter than the amount of memory indicated by the length data. The memory controller performs multiple write operations on memory beginning at a first location based on the address data and ending at a second location based on the length data. Each write operation writes the pattern data to a current location in memory, thereby initializing the arbitrary portion of memory with an arbitrary pattern based on the pattern data.

Abstract: There is disclosed a valve comprising a valve body, a bonnet, a bellows assembly and a translator assembly. The bellows assembly comprises a bellows and a bellows flange. The bellows flange is positioned between the bonnet and the valve body. The bellows flange defines a bellows flange opening, around which the bellows is attached. The translator assembly extends through the bellows flange opening. The bellows is attached to a periphery of the translator assembly. The invention also provides a power generating system comprising at least one turbine and at least one combustion system which comprises at least one fuel supply, at least one combustion canister, and at least one valve according to the present invention. There is also provided a method of constructing a valve.

Abstract: There is disclosed a valve comprising a valve stem threaded with a translator having a flow modulating region, in which rotation of the valve stem about its axis causes the translator to move axially relative to the valve stem. In one aspect, the threads on the translator and the valve stem threads have substantially similar coefficients of thermal expansion. In another aspect, a protrusion limits axial movement of the valve stem in one direction, the valve stem has at least one protuberance, at least one gland is engaged with the valve body, and at least one shim is positioned between the protuberance and the gland so as to limit axial movement of the valve stem relative to the valve body in an opposite direction. There are also disclosed power generating systems including such valves, and methods of constructing such valves.
