IPC: A61B19/00
Filed: 1993-02-24
Abstract: A specimen-receiving receptacle apparatus (10) for use in minimally invasive surgical procedures can be remotely opened and closed from a proximal end of the apparatus, outside of the patient (30). The apparatus (10) includes a belt (16) having substantial longitudinal rigidity so that the belt (16) can be forced longitudinally into the surgical site to open the specimen-retrieval receptacle (12) from a remote end of apparatus (10). The belt (16) can be longitudinally pulled out of the surgical site to close the specimen-retrieval receptacle (12) from outside of the patient (30). The belt (16) is relatively flexible or easily deformable along an open end (14) of the receptacle (12) without deforming substantially out of the plane of the open receptacle end (14). This is achieved by aligning the belt (16) with the respect to the open end (14) such that a large dimension of the belt (16) is aligned transverse to the plane of the open receptacle end (14). In a preferred embodiment, the belt (16) is extruded from nylon and has an elliptical cross-sectional shape.

Title: Steam cooling of gas turbine with backup air cooling
Inventor: CHEN ALLEN G
IPC: F02C7/18
Filed: 1995-04-27
Abstract: A gas turbine power plant in which a mixture of steam and compressed air, the mixture being primarily steam, is used to cool the rotating blades and stationary vanes in the turbine section. The air is bled from the compressor. The flow rate of steam that is mixed into the compressed air is adjusted so to maintain the pressure drop experienced by the compressed air as it flows to the turbine within a predetermined range. Consequently, the steam and air mixture has the same volumetric flow rate as if compressed air alone were being used. Thus, any sudden decrease in steam flow rate will automatically result in an offsetting increase in the flow of compressed air due to the decrease in the line pressure in the common line through which the air and steam flow to the turbine. Consequently, no control, isolation or check valves are utilized in the compressed air piping.
