Abstract: A reciprocable piston comprises a cylindrical body reciprocable within a hollow cylinder and at least two spaced ring seals disposed around the circumference of the cylindrical body. Within the cylindrical body there is a scavenging system that comprises: an internal chamber that is in fluid communication with a space between the spaced ring seals; and a one-way fluid passage that allows one-way fluid flow from the internal chamber to the cylinder chamber when fluid pressure within the internal chamber is greater than fluid pressure within the cylinder chamber. A method of scavenging fluid comprises collecting fluid that leaks by a piston seal and returning the collected fluid to the cylinder chamber from which it originated, through a scavenging system disposed within the piston.

Abstract: The inventions herein relate to novel games of chance and apparatus and methods for their play. In one embodiment, a multi-level game of chance is played by presenting the player with multiple options, where there is at least one positive option and at least one negative option. By way of example, at each level the player selects one of four boxes, where two have a monetary amount, and one has a strike. Optionally, the fourth box may comprise a ‘mystery box’, which requires a decision within a decision. When presented with the mystery box, the player may elect to open it or not. If they do not open it, game play resumes at the existing game level. If they open it, one of multiple options is presented, including a positive option and a negative option. In the preferred embodiment, the positive option could include: a multiplier of the winnings of the player, e.g., a double of the money in the player's account, or the updating of the safe level for the player.

Abstract: A device for characterizing a cell or particle includes a channel having an inlet and an outlet, the channel containing a moving fluid therein for carrying the cell or particle from the inlet to the outlet. The device includes a detector for detecting the presence of a cell or particle along portion of the channel, the detector including a first detecting position, a second detecting position, and a third detecting position. The device further includes a light source providing an optical gradient disposed within the channel and between the second and third detecting positions. A control system is coupled to the detector to receive and process detected signals from the detector. During operation, the amount of time that a cell or particle takes to flow through a first distance (i.e., its time-off-flight) is measured. The cell or particle is then flowed past a second, downstream distance in the presence of an optical gradient and its time-of-flight is measured.

Abstract: A variety of games and methods for enhancing game play are provided. In one aspect, a secondary or ancillary game is played in parallel with a first game, such as a lottery ball draw. Yet another game involves the selection of items which a player or participant believes had been selected by an audience as not being the most popular. In yet another aspect, an interstitial progressive sequencing of programming is provided, such as where a series of short segments are presented at differing times throughout an evening of prime time programming. Audience participation may be enhanced by permitting Internet access to the game system, and to permit remote users to play along as if they were in studio participants or part of the studio audience.

Abstract: The inventions herein relate to novel games of chance and apparatus and methods for their play. In certain embodiments, the existing lottery infrastructure is used in conjunction with electronic remote game play. A player receives a ticket identification number (TIN), optionally via lottery game play, and then plays an electronic game based upon the TIN. The remote system contains information associated with the TIN, for example, identification of which game will be played, and in a predetermined context, whether the player is to win or lose, and if they win, the form of the prize. In one embodiment, a multi-level game of chance is played by presenting the player with multiple options, where there is at least one positive option and at least one negative option. By way of example, at each level the player selects one of four boxes, where two have a monetary amount, and one has a strike.

Abstract: A continuous method for generating substantially submicron sized metal particles in a liquid dispersion of known viscosity. Metal carbonyl gas and an inert carrier gas, with an optional dilutant gas, are introduced into a heated liquid bath wherein the metal carbonyl decomposes into submicron sized pure metal particles. The particles are suspended in the liquid. The liquid is processed to form slurries and pastes.

Abstract: A reciprocating floor conveyor (10) including a support frame (12), and a conveyor floor (14), which is comprised of a plurality of laterally spaced-apart conveyor slats (16), a plurality of laterally spaced-apart holding slats (18), and a series of divider planks (20). Divider planks (20) are fixedly secured to the upper portion of support framework (12). Conveyor slats (16) are mounted on support frame (12) for longitudinal reciprocation between “start” and “advanced” positions. Holding slats (18) are mounted on support frame (12) for vertical movement between and “up” position in which the holding slats (18) are above the conveyor slats (16), and a “down” position, in which the holding slats (18) are below the conveyor slats (16).

Abstract: A paging system controller is accessible from a plurality of input devices, such as an attendant's position, a telephone interface, telephone night bell, programmable switch devices and digital data communications devices, and is user-programmable to respond to signalling activity sourced from such accessing devices to establish a paging connection to and perform prescribed audio/visual output paging signal functions with respect to one or a plurality of paging zones served by the system. The output paging signal functions include the transmission of audio tone and voice paging signals via an audio signal path from a paging source to one or more controllably energized paging loudspeaker amplifiers, the generation of one or more alert tones to a paging zone, talkback audio signalling from the paging zone to a telephone interface, the playback of prerecorded (audio/visual) messages from either or both of audio output (e.g. loudspeaker) and visual output (e.g. silent radio) devices.
