Abstract: A spectrometer includes a crystal analyzer having a radius of curvature that defines a Rowland circle, a sample stage configured to support a sample such that the sample is offset from the Rowland circle, x-ray source configured to emit unfocused x-rays toward the sample stage, and a position-sensitive detector that is tangent to the Rowland circle. A method performed via a spectrometer includes emitting, via an x-ray source, unfocused x-rays toward a sample that is mounted on a sample stage such that the sample is offset from the Rowland Circle, thereby causing the sample to emit x-rays that impinge on the crystal analyzer or transmit a portion of the unfocused x-rays to impinge on the crystal analyzer; scattering, via the crystal analyzer, the x-rays that impinge on the crystal analyzer; and detecting the scattered x-rays via a position-sensitive detector that is tangent to the Rowland circle.

Abstract: The invention described herein is a spectrometer having components allowing remote orientation of crystal analyzer and detector.

Abstract: The present invention provides a holder and dispenser of rolled products such as paper, plastic, foil, tape and other goods with magnetic resistance. The dispenser generally includes a base and a cage that supports the roll of material and rotates relative to the base. A magnetic resistance mechanism is generally located between the base and the cage. The magnetic resistance mechanism creates forces that act to resist rotation of the cage relative to the base.

Abstract: A collapsible chess clock including four interconnected generally planar panels that are operable to be erected into opposing player, digital time information centers wherein two of the panels reflect a player time decrement pause capacity upon completion of a player move and an on the clock position of an opposing player and two the panels reflect each player's time remaining to forfeiture of the game.

Abstract: A display system is configured to display a stereoscopic three dimensional relief effect in aerial space from a two dimensional image source. The display system has a reflector, having a generalized cylindrical concave surface. The two dimensional image source is arranged between the first side and the second side facing the generalized cylindrical concave surface. The reflector reflects light from the two dimensional image source outward as an aerial image. The aerial image exhibits the stereoscopic three dimensional relief effect. A support structure is operably connected to the reflector and the two dimensional image source. The reflector and the two dimensional image source are adapted to be individually rotated and tilted relative to one another while their position is physically secured.

Abstract: Fire resistant glazings comprise a fire resistant interlayer based upon a silicate waterglass are characterized by the incorporation of aluminum ions. The aluminate is incorporated as a solution which has been partially neutralized using hydroxycarboxylic acid which is preferably citric acid. The incorporation of aluminum provides glazings have improved fire resistance and impact properties.

Abstract: A spout for use with a container for dispensing a substance (e.g., a condiment) from the container such that any remaining substance exterior to the container adjacent the spout may be allowed to drain back into the container. A lid may be engaged with a container at an engagement portion. A spout portion of the lid that is positionable between a dispensing position and a storage position may define an orifice. The orifice may provide for communication between an interior volume of the container and an exterior of the container. Thus, the substance may be dispensed through the orifice. Furthermore, when in the storage position, the spout portion may direct any remaining substance on an exterior portion of the spout portion through the orifice and back into the container. Thus, a cleaner and more sanitary top of the container may be realized.

Abstract: The present invention provides lottery tickets each of which incorporates one or more set(s) of random results data generated by random data generating software. Each set of random results data corresponding to possible results of game play, a sports event or a sporting contest, and incorporates a verification code for each set of random results data.

Abstract: Bilayer materials are produced by drying a solution of an alkali metal silicate upon the surface of a flexible backing material until a flexible silicate film is produced. The film may be separated from the backing material and incorporated into laminated fire resistant glazings. The alkali metal silicate solution preferably comprise a surfactant. The bilayers may be transported or stored before the flexible silicate film is separated and incorporated into a glazing.

Abstract: A single hand, horizontal, paper towel dispenser for paper towel rolls designed to assist in creating a tear of a selected number of sheets by providing friction from a static tear bale. The single hand dispensing device can optionally employ friction surfaces and various additional structures to allow a user to grasp paper towel segments and tear off a desired length of paper towel segments with one hand.
