  • Patent number: 4577756
    Abstract: A protective canister for computer discs comprises a hollow tube and a pair of end caps for closing the tube and fixing a central post therein. A stack of alternate computer discs and spacers having aligned central apertures is loaded onto the center post and clamped in the canister by way of a pair of platforms carried by the end caps about the central post. The elements of the canister are preferably constructed from hydrocarbon-based polymers and, after loading, the canister is sealed in shrink film so that the discs are protected in an environment which is free of particulate matter.

  • Patent number: 4225174
    Abstract: A sanitary refuse device for collecting waste products such, for example, as the droppings of dogs, cats, and other animals. A hollow, cane-like, substantially vertical handle has a pistol-type grip at its upper end and a pair of normally open, spring-biased, pick-up jaws at its lower end, one of the jaws being fixedly connected to the lower end of the handle and the other jaw being pivotally mounted so as to swing to and from the fixed jaw. A trigger in associated relation with the piston-type grip is connected to the pivoted jaw through the medium of an actuating rod which passes through the handle and normally exists under compression in order to maintain the pivoted jaw in its open position against the action of the associated spring. Retraction of the trigger places the actuating rod under tension so that it becomes a pull rod and causes the pivoted jaw to swing towards the fixed jaw into a closed position.
