Abstract: A cartridge for a disc-shaped recording medium, the cartridge including a cover shell and a base shell which house a flexible, magnetic recording medium therebetween. A movable shutter is provided along a front edge of the cartridge for covering, when in the closed position, an opening in each shell which allows a read/write head to access the recording medium. The shutter is windowless and has triangle-shaped portions which cover the read/write head access openings. The shutter includes a raised rib along its periphery and has a rounded corner. A raised rib may also be provided on the cartridge shell adjacent the read/write head access opening to prevent debris particles from entering the interior of the cartridge via the head access opening. The shutter is reinforced to prevent bending and has a rounded corner to minimize the chance that the shutter corner will become snagged on some other object, such as loose clothing.

Abstract: An article support adapted for adhering to a substrate is described. The article support preferably includes a base member, a stretch release adhesive tape adhered to that base member, and some mechanism for gripping the stretch release adhesive tape. These items are arranged so that when the base member is adhered to the substrate by the stretch release adhesive tape, the base member can be removed by pulling on the gripping means at an acute angle from the surface of the substrate. Gripping means which resist disassociation from the stretch release adhesive tape during the removal of the base from the substrate are disclosed, including handle types. The base member can be generic, suitable for attaching various types of support members via, for example, complimentary dovetail slides. In such cases, provision such as a latch can be made to temporarily lock the support member to the base member.

Abstract: An adjustable tray assembly adaptable for use in desk drawers having side walls spaced at various distances. The tray assembly includes a first portion having a plurality of open top receptacles and a support lip projecting away from one side, and a second portion also with a projecting support lip and mounted on the first portion to affording relative movement between the portions to change the spacing between the first and second support lips so that they can be supported on the upper edge surfaces of the side walls of the drawers of different widths with the first and second portions bridging therebetween. The tray assembly can also include dispensers for office supplies including note paper, tape flags and tape; the tape dispenser being of a novel low profile design.

Abstract: A pad assembly comprising a multiplicity of flexible sheets each having a band of repositionable pressure sensitive adhesive coated on its rear surface adjacent and spaced by a small predetermined spacing from a first edge. The sheets are disposed in a stack with the band of repositionable pressure sensitive adhesive on each sheet adhering it to the adjacent sheet in the stack; and a layer of padding compound is disposed over and adhered to aligned first edges of the sheets in the stack. The padding compound allows, after the band of repositionable pressure sensitive adhesive on the rear surface of one of the sheets in the stack is separated from the front surface of the adjacent sheet in the stack, that one sheet (and any sheets above it) to be pivoted away from that adjacent sheet while remaining adhered to the adjacent sheets.
