    摘要： A fluid compressor comprises a casing containing liquid and having located within it a shaft driven radial impeller for pressurizing the liquid before it is fed to a further rotatable structure. By rotation of the impeller and the further rotatable structure, the high pressure liquid compresses a gas or vapor within the compressor casing and expels it from the casing through an outlet port therein. The high pressure liquid inlet end of the rotatable structure is partially shrouded by a shroud structure to restrict the input of high pressure liquid to part of the rotatable structure. The shroud structure has an opening therein which allows the high pressure liquid entering the rotatable structure to be depressurized and returned to the inlet end of the radial impeller after compressing the gas or vapor. By so doing, further gas or vapor for compression will be drawn into the compressor casing.

    摘要： A replica eye with programmable iris illumination and a method of making the same is provided. The replica eye includes a programmable lighting element having a planar base with electrical pins outward of a centrally disposed light source is electrically coupled via the pins to one or more electrical connections. One end of a transparent cylinder approximately coextensively abuts the light source. The outer portions of the planar base and its electrical connections are folded into a folded assembly that is received into and adhered along an inner circumferential wall of a ring. The electrical connections are further adhered along a rear portion of the ring and planar base. A semi-spherical dome sandwiches an opaque body to an opposing end of the transparent cylinder, thereby defining an illuminable iris and pupil, respectively.
