Abstract: A popper for propelling powder. In one example embodiment, a powder popper includes a hollow housing that includes an internal powder chamber, a bottom plug positioned at the bottom of the powder chamber, powder positioned in the powder chamber above the bottom plug, a seal for preventing the powder from leaking out of the powder chamber past the bottom plug, and means for propelling the powder from the powder chamber upon activation of the powder popper, which causes the powder to expand in the air into a small cloud of the powder.

Abstract: Motorized snare. In one example embodiment, a motorized snare includes a housing, a snare cable extending from the housing and terminating in a noose, a retraction mechanism at least partially positioned within the housing and including a motorized reel attached to the snare cable, and a trigger mechanism configured, upon being triggered, to cause the motorized reel to reel in at least a portion of the snare cable into the housing.

Abstract: A nut shell filter allows the shell filter media to be scrubbed without being removed from the filter vessel. In order to protect the vessel from pressure surges which can occur during the scrubbing cycle, pressure applied during the beginning of the scrubbing cycle is contained within a scrubber tube such that the filter vessel is not subjected to pressure surges which occur at the beginning of the scrubbing cycle. The scrubber tube and scrubber filter tube may either be disposed within the filter vessel or outside of the filter vessel.

Abstract: The system of the present invention has a flexible bladder designed to provide for the transfer of liquids from a storage/transport unit to vehicles without the necessity of pumps and/or motors. The system includes a flexible, collapsible bladder that uses compressed gas or air, or a pressurized liquid, to pressurize the unit. The bladder is constructed with a flexible internal diaphragm which extends from a portion of the interior of the bladder, and separates the ends of the bladder. The system further comprises removable means to inject air, gas or fluid into the first end of the bladder and removable means to inject and expel the fluid stored in the second end of the bladder.

Abstract: Disclosed are a switching system and method for a Small Computer System Interface (SCSI). The SCSI has a plurality of ports coupled to devices having differing priorities including a highest priority (initiator) and lower priorities (targets). The present invention interconnects a plurality of the highest priority initiator devices to the lower priority target devices. A plurality of analog switches are each coupled to one of the initiator device ports and to the lower priority target device ports, preferably on a singular target bus, for selectively interconnecting the coupled initiator device to the lower priority target device ports. A controller is coupled to the initiator devices and to the plurality of analog switches, and is responsive to requests for connection from the initiator devices for arbitrating amongst the initiator devices to operate the analog switches to interconnect only one of the initiator device ports to the lower priority target device ports.
