A screen printing machine is disclosed which has a screen frame mounted on a swivel mount shaft. The swivel shaft for the screen frame extends through the center plane of the screen frame which extends perpendicularly with respect to the movement of the squeegee. Devices are provided which can raise the screen frame on both sides of the swivel shaft. By means of this construction, while the advantages of a compensation of errors are maintained, the screen printing machine may be used for movements of the squeegee in both directions. The new screen printing machine is particularly well suited for the printing of printed circuit boards.

An ASIC device embedded into the memory subsystem of a computing device used to accelerate the transfer of active memory pages for usage by the system CPU from either compressed memory cache buffer or the addition of a compressed disk subsystem for improved system cost and performance. The Compression Enhanced Dual In-line Memory Module of the present invention uses parallel lossless compression and decompression engines embedded into the ASIC device for improved system memory page density and I/O subsystem data bandwidth. In addition, the operating system software optimizes page transfers between compressed disk partitions, compressed cache memory and inactive/active page memory within the computer system. The disclosure also indicates preferred methods for initialization, recognition and operation of the ASIC device transparently within industry standard memory interfaces and subsystems. The system can interface to present operating system software and applications, which enable optimal usage for the compressed paging system memory environment. The integrated parallel data compression and decompression capabilities of the compactor ASIC mounted on industry standard memory modules, along with the software drivers and filters of the present invention keep recently used pages compressed in the system memory. Additional performance is gained by the transfer of compressed pages between the system memory and the disk and network subsystems. In addition, the present invention may reduce the amount of data transferred between distributed computers across the LAN or WAN by the transmission of compressed page data between remote systems or distributed databases.

A paving stone, made from concrete material, having a one-piece plane surface and two strip like support attachments arranged on each lateral surface. These support attachments form joints between adjacent paving stones in a laid composite structure. On each side, two support attachments are symmetrically arranged with center spacings relative to the planes of symmetry, wherein these planes of symmetry extend through the centers of adjacent lateral surfaces. When these paving stones are stacked next to each other, the support attachments from a first paving stone is disposed adjacent to a support attachment on an adjacent paving stone.

A gas turbine including at least one compressor, one combustion chamber, and at least one turbine including at least one rotor and at least one generator coupled to the at least one rotor is provided. The at least one turbine is coupled to the at least one compressor. Once the gas turbine is shut down, the at least one generator can be used as a motor in order to drive the at least one rotor for a predetermined time period following shutdown of the gas turbine and thereby effect a uniform cooling of the rotor. A method of operating a gas turbine is also provided.
