    摘要: Inverse gas-chromatography apparatus for investigating the properties of a solid material, having a carrier fluid, comprising at least two fluid components (typically water and an inert gas); a second flow comprising the carrier fluid components and probe material; a temperature controlled column, for holding the solid material; a switch for selectively passing the flow of carrier fluid and the second fluid flow through the column; a detector for detecting the passage of the probe material through the column. The relative proportions of the fluid components in the flow of carrier fluid and the second fluid flow can be controlled.

    摘要: A housing has two side walls extend upwardly from a floor to define a channel extending between a primer inlet and a primer outlet. A lanyard clip is fastened to the side walls adjacent the primer inlet, compressing the clip releases it, allowing primers to be loaded through the primer inlet. A spring is riveted to the housing floor with a protruding spacer segment facing the primer inlet, and a restraint segment facing the outlet. Multiple primers are restrained between the spring spacer segment and the primer inlet, yet the spacer segment may be deflected by pushing a primer toward the primer outlet until it is positioned on the restraint segment, and presented for engagement on the primer holder of an in-line action muzzleloading rifle. Pulling the dispenser displaces the primer to move along and depress the restraint segment, and dispensing it. A floor cut-out acts as a decapper.

    摘要: A method and apparatus for maintaining a liquid-frozen solid slush mixture in a vessel at a desired total slush mixture and desired solids content during conditions under which the solids in the slush mixture in the vessel are melting. The method comprises introducing fresh slush mixture to the vessel, while removing liquid from the vessel--both at rates directly proportional to the rate of solids melting in the vessel. The apparatus comprises an auxiliary vessel containing slush mixture and means for transferring slush mixture to the main vessel at one rate, means for transferring liquid from the main vessel to the auxiliary vessel at another rate, and means for controlling the transfer rates in a prescribed manner.
