Filed: 1990-08-14
Abstract: A process for the liquefaction of natural gas is disclosed wherein expansion valves for low-level multicomponent refrigerant and liquefied gas product streams are replaced with process-loaded turboexpanders (141, 151) having liquid inlet streams. Each turboexpander is coupled with a compressor or pump (142, 152) so that expansion work extracted from a given stream is used directly to compress or pump the stream prior to cooling and expansion. The use of process-loaded turboexpanders reduces the minimum work of liquefaction and increases the liquefaction capacity of the process.

Inventor: STIERMAN ROGER J
IPC: C25D7/12
Filed: 1990-01-09
Abstract: @ This disclosure describes a plating fixture to hold a silicon wafer containing integrated circuits in a metal plating bath. The wafer (11) is coated with photoresist to a thickness equal to the desired bump height and the desired bump locations patterned by standard photolithographic techniques. The wafer is then loaded in the fixture and the fixture placed in the plating bath so that the patterned side of the wafer is facing up and the plating anode (3) is located directly above the wafer (11). Systems presently on the market have the wafer positioned with the patterned side facing down and the anode located below it, or the wafer faces sideways and the anodes are access from it. These present systems allow air to be entrapped in the pattern of the photoresist, lowering yield by under plating or uneven plating of the bumps on the wafer. This disclosure prevents such yield loss and also allows cleanups on the wafer after it is loaded in the fixture.

Abstract: A system and method for fusing or merging video imagery from multiple sources such that the resultant image has improved information content over any one of the individual video images. The sensors generating the video imagery are typically responsive to different spectral content in the scene being scanned, such as visible and infra-red or short and long wavelength infra-red, and the like. This permits real-time, high pixel rate operation with hardware implementation of moderate cost and complexity. Image enhancement by frequency content specification is another advantage of this approach. The flexibility permits application to many different video formats and line rates.

Abstract: The machine tool is intended for workpieces (1) of wood, synthetic material or the like and has a tool-bearing spindle and a transporting part (3), on which the workpieces (1) to be machined can be transported along the tool. They can be fed into the machine from a feeding region, which has an insertion opening (11), which can be partially closed by a run-in guard (9). The insertion opening (11) can be completely closed by means of at least one closing part (38) which can close transversely to the direction of advancement (15) of the workpieces.
