Abstract: A packaging and disposal system for sealing waste and related materials within flexible plastic tubing for odorless and sanitary disposal. Improvements in the latch, including the addition of a transverse mounted latch spring, and improvements in the support retention springs serve to increase the ability of the device to operate efficiently and effectively and reduce the potential of accidental spills or other exposure of the waste package. The latch requires two independent motions to actuate and incorporates a transversely mounted latch spring. The reduced cross-sectional area of the retention spring design concentrates force applied to the package to increase the effective holding ability of the system.

Abstract: A carrier supporting multiple filters is inserted jointly with the filters into an air sampler. The carrier includes an indexing structure to ensure correct positioning within the air sampler. A memory device physically associated with the carrier stores sample collection data provided by the air sampler. The stored data can be read by a read/write station at a lab, and transmitted to a processor. The processor also receives a weight reading from a communicating balance for each collected sample, and calculates therefrom mass concentration for each sample.

Abstract: An electronic terminal of the type employing a card reading device mounted within the interior thereof accessible through an input port formed in a wall of the terminal. A shield formed of an elastomeric material is mounted adjacent the input port of the card reader to prevent the entrance of debris into the interior of the terminal. The shield provides at least two opposing movable overlapping flaps extending over the card reader input port. The flaps are readily flexible to allow a card to slide therebetween, and automatically flex back to an overlapping closed position when the card is withdrawn. Locator pins and mating holes are provided in said flaps to assure a consistent return to the closed and sealed position. In one embodiment, the shield is made from two half sections which may be either separated or connected via a flexible bridge.
