    摘要: A dimmer for adjustably attenuating light to a fiber optic bundle. An opaque vane has a movement axis with a band on each side. One band has a substantially opaque portion which blocks about 50% of the light of a spot directed against the vane, and an opaque portion for passing about 50%. The other band has transmission slots interspaced between opaque bars, proportioned and arranged to pass varying amounts of light, all as a function of the position of the vane. The light passed by the bands is additive.

    摘要: A single axis three way valve for endoscopes. The valve has a repose, closed setting and two active settings. In one active setting, a common port to the endoscope is connected to suction, and in the other active setting it is connected to a source of irrigation liquids. The valve has two spools, one of which is connected to a finger pad for actuation, and which is spring-loaded to a closed position. The other spool is spaced from the first, and also is spring-loaded closed . The first valve is opened by initial movement. Further movement closes its port and abuts the other spool to open its respective port.
