Abstract: The invention includes methods of secure redemption for use with and without automation, such that the redemption system is resistant to a dishonest redemption clerk using the system in reverse to locate a correct answer and use that information to defraud the game sponsor.

Abstract: A Multiple Play Lottery Game for use as a promotional game or casino-style game. The game may be adapted to a dispensable card or a video format; particularly, it incorporates elements of active play by the player and player determination of the level of risk engaged as well as attributes of prize control.

Abstract: A gas-propelled dispensing device for a liquid container has a high pressure vessel and a pressure gas vessel. A pressure reducing valve is provided between the two vessels so that as consumed, replacement gas is supplied to the low pressure chamber at a controlled moderate pressure. A relatively long tube delivers liquid from the bottom of the container, and a gas duct in the discharge head is connected to the low pressure vessel. Both ducts are opened by pressing the discharge head so that gas flows through a venturi passageway to draw liquid from the container which is propelled outward by the gas in a spray. Liquid carbon dioxide is a preferred nontoxic, nonflammable source of the gas propellant.

Abstract: A skill game for home or promotional use in stores or in fast food restaurants that provides a player with a degree of self-determination and provides an inducement to perspective customers. The score is dependent on the player's skill and his confidence in his answer. This game provides a variable scoring system where each additional clue which is revealed reduces the score of a correct answer.

Abstract: A barrier layer ceramic capacitor and a method of making the same, using barium plumbate or modified barium plumbate as the base material. The fabricating process is a one step process requiring a maximum sintering temperature of 1000.degree. C.

Abstract: An apparatus and method for generating high power electro magnetic radiation in the millimeter or submillimeter range axial injection and adiabatic compression of an electron beam using large electric fields in an evacuated AXIOM (Axial Injection Orbitron Maser).

Abstract: A controlled porosity dispenser cathode and method of manufacture therefo using chemical vapor deposition and laser drilling, ion milling, or electron discharge machining for consistent and economical manufacturing a cathode with pores on the order of 0.2 to 2 .mu.m in diameter.

Abstract: A method and apparatus for converting an ion beam from a standard ion gun into a neutral particle beam by the processes of resonance neutralization followed by Auger deexcitation and/or Auger neutralization, established by directing the ion beam to pass in the proximity of a suitable metal surface.

Abstract: A device for detecting small amounts of alkanes such as methane, ethane, propane, and butane gases, comprising an optical waveguide and a light source for propagating light therethrough; apparatus for obtaining samples of air to be tested; apparatus for adding water vapor to these air samples to yield gas mixtures with at least a 30% relative humidity; and means for flowing these mixtures over the surface of the optical waveguide at a rate sufficient to favor condensation of the mixture on the waveguide surface to thereby form a thin film thereon. The presence of alkanes is determined by detecting the intensity of the light after propagation through the optical waveguide and then comparing that detected intensity to a reference. In a preferred embodiment, the optical waveguide is an optical glass capillary in which the surface is closed in a lens-like configuration at the detector end.
