Abstract: Implementations disclosed herein provide a compact and easy-to-maintain piece of downdraft equipment for use in facilities with limited floor space that includes a unique air sampler to ascertain the state of dirty air entering the downdraft equipment. The air sampler utilizes a removable portable air quality detector that can be moved to further locate the source of a contaminant when detected. The portable air quality detector may also be replaced when defective without disassembling the downdraft equipment.

Abstract: An access control system which relies at least in part on a non-networked path for permitting an entity access to a secured location; the entity identified by the system by means of a unique entity identifier accorded the entity; entry to said secured location secured by a barrier; said barrier identified by the system by means of a unique barrier identifier accorded the barrier; said system including a local access unit located local to the barrier; said system including a barrier controller for actuation of the barrier; said local access unit issuing an open signal to the barrier controller whereby the barrier permits the entity access to the secured location if and only if data contained in a token communicated from an un-trusted communications device to the local access unit is verified by the local access unit with respect to at least a first parameter by the local access unit.

Abstract: A carding engine guard arrangement includes carding engine (10) having a longitudinal axis, and respective guards (11) arranged along each side of the carding engine (10), in which at least one of the guards includes a support structure (25) arranged along one side of the carding engine (10), and a door arrangement (12) pivotally mounted on the support structure (25) to pivot about a substantially horizontal hinge axis (13, 17, 20) at or near to the upper edge of the door arrangement between a closed position guarding the side of the carding engine and a raised position allowing full access to the carding engine throughout its length, when the latter is inoperative. In a preferred arrangement, the door arrangement includes upper and lower door panels (14 and 15) in which lower panel (15) is first hinged upwardly about its upper edge (16), and thereafter the overlapping door panels (14 and 15) are hinged together upwardly as a unit about the upper hinge axis (13, 17, 20) to the raised access position.

Abstract: A card is provided with a cover assembly adapted to provide enhanced cleaning efficiency. The cover is 4 covers in one with each part being set at a prescribed distance from the carding cylinder to induce increased cleaning. Air drawn through a gap at the first cover disturbs and intermingles with the fibers and loosen dirt. The fourth cover exerts centripetal action to strip away waste from the fiber.
