Abstract: A hot ash vacuum is provided with a canister having an outer housing and a concentric inner housing; a cap for the canister has a vacuum motor extending into the inner housing; a flexible hose is coupled through the cap and communicates with the inner housing at one end and a nozzle at the other end; and a dust collector communicating through the cap with said inner housing for collecting hot ash dust therefrom.

Abstract: A vertically extensible seat bracket assembly for fishing boats or the like, characterized in that most of the assembly mounts below the boat deck when in this lowered position, the seat may be raised and locked in its elevated position with a simple lift-and-twist motion. The seat mount assembly includes a shock absorbing spring, as well as a feature which allows easy removal of the seat for storage while the major portion of the seat bracket assembly remains below the boat deck.

Abstract: On a helicopter having a main fuel tank and outer curved walls with connector lugs thereon, an auxiliary fuel tank for each side of the helicopter, each tank being of aerodynamically streamlined configuration having an outer convex wall, a top rounded wall, a bottom rounded wall and an inner concave wall for abutment against said outer curved wall of said helicopter; a plurality of connector ears on said tanks for attachment to said lugs; said connector ears having a breakage point of 5000 PSI; said connector lugs having a breakage point of less than 5000 PSI, whereby said auxiliary fuel tanks may break away from said helicopter in the event of a crash landing; gravity feed lines from the helicopter's main fuel tank to said auxiliary tanks whereby said tanks are filled from said main fuel tank when said main fuel tank reaches a predetermined high level, and auxiliary pumps in said auxiliary fuel tanks for pumping the fuel from said tanks to said main fuel tank when said main fuel tank reaches a predetermined

Abstract: An adjustable head support comprising a base support having a lower rail and an upper rail; said lower rail for engaging a support surface such as a mattress; said upper rail having a first means for adjustably supporting a pad upon which patient's chin rests and having a second means for adjustably supporting a pad upon which a patient's forehead rests, and said pads having hydraulic means to ensure maximum comfort of a patient while lying in the prone position.

Abstract: There is provided a hunting blind comprising an upper frame including a peripheral frame structure, top reinforcing side members and a cross strut; gun-support bars attached to and vertically spaced from said upper frame; a bottom frame structure separably attached to said upper frame; a cover extending about said upper frame and said lower frame, said cover having a plurality of window openings, and a flap on the inside and a flap on the outside of said window openings to open or close said openings at the discretion of a hunter occupying said blind.

Abstract: A drill bit having cutting cones is provided with a plenum chamber communicating with orifices for supplying lubricants to the bearings of the cutting cones and orifices communicating with the plenum for supplying cutting liquid and gaseous fluid to jet nozzles on the periphery of the drill bit for supplying a low volume of said cutting liquid and gaseous fluid to the area below the drill bit cutting cones thus reducing the velocity of the cuttings and orifice communicating with the plenum chamber and a meter for measuring the volume of cutting liquid and gaseous fluid being supplied to the drill bit.

Abstract: A waste gas burner is provided with a flare stack for receiving waste or hazardous gas, a chamber for receiving said gas from said flare stack, said chamber having variable openings for the passage of air, apparatus for increasing the velocity of the gas in the chamber creating a vacuum whereby ambient air is drawn into the chamber and mixed with the gas, a flare tip on said chamber for the passage of mixed gas and air and an ignitor adjacent the flare tip for igniting the gas mixture of gas and air.

Abstract: This invention comptemplates providing a tape cassette cleaner which is light in weight, simple and easy to manufacture and comprises a housing having a forward section in which there is a rotatable spool to be engaged by the drive mechanism of a tape recorder. The housing has a rearward section having a spool therein which is driven by the first spool by a drive belt. The rear section has a spindle extending from the pulley wheel and is adapted to engage a spool of a tape cassette. Adjacent the spindle is a projection which is adapted to engage the other spool of a tape cassette. Wiping pads are provided on supports which wiping pads engage the tape or film of a tape cassette. When the forward section is inserted into a tape recorder, the pulley wheels are driven by the interconnecting drive belt and the tape cassette tape is caused to move past the wiping surfaces to clean dirt and oxide therefrom. One of the wiping surfaces may be saturated with a cleaning solution manually.

Abstract: A drill bit for drilling into earth formations comprising a plurality of sections having connection means to connect said sections to form a unitary drill bit; means in said plurality of sections for storing and delivering lubricants to the cutting cones; and wear bar segments on said plurality of sections to form continuous wear bars about the periphery of said unitary drill bit thus reducing the wear on said unitary drill bit.
