Title: High efficiency dual output light source
Inventor: DAVENPORT JOHN M
IPC: G02B6/00
Filed: 1994-10-13
Abstract: A centralized lighting system is provided having a high intensity light source which is disposed at approximately the first optical focal point of an ellipsoidally shaped reflector member. A mirror member, disposed in advance of a second optical focal point associated with the reflector member, receives light output from the light source and is constructed so as to divide the light output into at least first and second beam portions. The mirror member is further effective so as to separate the first and second beam portions by at least 90 degrees relative to one another. Corresponding at least first and second optical transmission members are receptive of the first and second beam portions and are effective for communicating the light output to locations remote from the light source. In one embodiment, the mirror member is V-shaped and is constructed of first and second mirror segments joined together so as to form an angle of less than about 85 degrees therebetween. The mirror member is effective for dividing the beam portions so that such beam portions are substantially equivalent to one another in terms of intensity, shape and color.      The V-shaped mirror member is further effective for separating the first and second beam portions by approximately 180 degrees relative to one another.

Title: Waterpowered fish decoy and jigging device
Inventor: DUBRISKE PAUL C
IPC: A01K97/00
Filed: 1994-09-15
Abstract: TITLE - WATERPOWERED FISH DECOY AND JIGGING DEVICE     ABSTRACT      A fishing device used for trolling or in moving water where sportfishing is shown which employs the force of water, as the device moves through it, to engage a propeller that turns a shaft engaging a cluster of gears.  The gears alternately engage a worn shaft and a Spool. The spool retrieves a cable, to which, is attaches a variable parachute drag.  This drag incorporates a release mechanisim to which a fish line is attached.  The cable, while being retrived on the spool, acclerates the lure attached to the fishline.          The lure appears to be  a live baitfish that is swimming rapidly to avoid a predator.    The worm shaft engages a pawl, which is carried in a pawl retainer to travel along the worm shafts axis and thereby disengaging the spool, which is rotatably mounted on an axle type shaft mounted parallel to the worm shaft, from the gear cluster.  The spool has the cable wrapped aroung it while being engaged in the gear cluster and when it becomes disengaged the force of the water against the parachute drag which is attached to the cable causes the cable to unwind.  During the unwinding the lure is suspended motionless and begins to flutter as it sinks or floats up thus, resembling a stunned baitfish.  The device which is shaped like a fish and incorporates a prominent lateral line, appears to be a feeding predator.  The apparent feeding scene as witnessed by other fish triggers the instinct of those fish to feed.    The propeller is clear and virtually invisible underwater, allowing the device to more closely imitate a natural fish.       This imitating of the feeding scene and the consequent enticement of other fish is desirable to fishermen and enhances the opportunity to catch fish.  The device is easy to disassemble allowing for color changes, economical to buy and provides an enhanced fishing technique and thus, is enjoyable for sport-fishermen.

IPC: F04B17/03
Filed: 1994-11-15
Abstract: A volumetric pump for administering intravenous fluids to a patient comprises a housing having an elongate cavity therein with an open and a closed end.      A resilient sheet of material having a centrally-located aperture covers the open end, and a pump shaft is slidably disposed through the aperture to form a sphincter seal therebetween. An inlet conduit leading from a fluid source (an IV bag) passes through the housing into the cavity near the open end thereof, and an outlet conduit leading to a fluid sink (the patient) passes through the housing from the cavity near the closed end thereof. The shaft is driven back and forth in reciprocating motion inwardly and outwardly of the cavity to produce, respectively, a positive pressure forcing fluid out of the outlet conduit to the fluid sink, and a negative pressure forcing fluid from the fluid source through the inlet conduit.
