Abstract: A flow straightener is disclosed for a hydrogen cyanide reaction process that maintains a substantially uniform velocity profile to provide a plug flow with reduced flow rotation within a mixing vessel. This results in improved performance and production of hydrogen cyanide.

Abstract: The present invention relates to an improved process for producing hydrogen cyanide. More particularly, the present invention relates to a commercially advantageous process for producing hydrogen cyanide at enhanced levels of productivity and yield while using natural gas comprising at least one C2+ hydrocarbon, carbon dioxide, and hydrogen sulfide. The natural gas is purified to be used as a source of methane-containing feedstock.

Abstract: The present invention relates to an improved process for producing hydrogen cyanide involving a heat exchanger comprising a plurality of tubes, wherein each of the plurality of tubes comprises a ceramic ferrule extending through the entrance of the tube, each ferrule comprising an insulation layer surrounding at least a portion of the ferrule, and one or more washers, wherein at least one of the one or more washers surrounds the ferrule above the entrance of the tube, wherein the ceramic ferrule is spaced apart from the tube.

Abstract: A game controller, which is used in conjunction with a game device, includes a housing, a light-emitting device provided within the housing for producing flashing light of varying intensity, and a circuitry provided within the housing and generating control signals in response to signals received from the game device to control the intensity and the flashing frequency of the light emitted by the light-emitting device.

Abstract: A key-operating device includes a shell confining a chamber therein and connected to a video game apparatus with depressible keys, a lever pivotally mounted in the chamber and having protrusions projecting toward the keys, a wheel surrounding and connected to the shell and rotatable relative to the shell, and an actuating member projecting from the wheel and engageable with the lever in such a manner that rotation of the wheel results in engagement between the actuating member and the lever so as to permit fulcrum movement of the lever and pressing of the keys by the protrusions.
