Abstract:
The present invention relates to a method of producing hydrogen gas and carbon dioxide in a catalytic reaction from formic acid, said reaction being conducted in an aqueous solution over a wide temperature range and already at room temperature (25° C.). The reaction is advantageous because it can be tuned to take place at very high rates, up to about 90 litre H2/minute/litre reactor volume. The gas produced is free of carbon monoxide. The method of the present invention is particularly suitable for providing hydrogen for a motor, fuel cell or chemical synthesis.
Abstract:
An arrhythmia control system and method having automatic determination of the tachycardia confirmation interval. The interval is dynamically set at the minimum of an absolute detection interval and a value calculated as a function of either average sinus interval or tachycardia cycle length or both. The continued presence or the reversion of a pathologic tachycardia can be reliably confirmed, particularly when the patient experiences an elevated heart rate due to, for example, exercise, prior to onset of the tachycardia.

Abstract:
A new procedure for constructing cryogenic storage tanks involves erecting a freestanding metal liner. The liner is sized and configured to withstand the hydraulic forces the concrete wall of the tank being poured without the need for temporary stiffeners on the inside surface of lower portions of the liner. Lateral tension ties can be connected to anchor ties on an outward surface of the liner and used to tie the liner to outer formwork. These ties may be spaced up to about 2 m apart. Studs can also be provided on the outer surface of the liner, and a cylindrical ring of cryogenic steel can be integrated into the liner.

Abstract:
Novel chemical compounds of the general formula K+A−, in which K+ is a 5- or 6-membered heterocyclic ring having 1-3 hetereo atoms, which can be independently N, S, or O; with the proviso that at least one of the hetereo atoms must be a quaternized nitrogen atom having a —R′CN substituent, wherein R′ is alkyl (C1 to C12);the heterocyclic ring having up to 4 or 5 substituents independently chosen from the moieties: (i) H; (ii) halogen or (iii) alkyl (C1 to C12), which is unsubstituted or partially or fully substituted by further groups, preferably F, Cl, N(CnF(2n+1−x)Hx)2, O(CnF(2n+1−x)Hx), SO2(CnF(2n+1−x)Hx)2 or CnF(2n+1−x)Hx where 1

Abstract:
A board game and method of playing the same for teaching strategy and providing entertainment. The board game and method of playing the same includes a game board having a top surface has game play space thereon. The game play space is divided into a plurality of triangles radially extending outwardly from a central portion of the game board such that the each of the triangles has an apex positioned generally adjacent to the central portion. The triangle is divided into four rows such that a first through fourth consecutive row is defined. The fourth row is generally adjacent to the central point. Each of the rows is subdivided into a plurality of game spaces. A plurality of game pieces is used for positioning on the game spaces. Each card of a first deck of cards has an action indicia thereon. Each card of a second deck of cards has an action indicia thereon. Each of the players playing chooses a triangle. The players take turns drawing one of the second deck cards and performing the action indicia thereon. The player who draws a second deck card having action indicia thereon indicating winning the game and fills all of the game spaces with a game space wins the game.
