Abstract: A capless retractable sealed marking instrument has a sealed chamber incorporated in a marker casing. The sealed chamber includes a chamber, a wiper ring, and an annular rim and a seal portion with a cross-slit aperture defining surfaces or flaps which are moved out of contact by a linearly-advanced marker nib to open the seal for extension of the marker nib. The configuration of the disk provides positive sealing force between the lateral sealing surfaces of the seal flaps. Retraction of the marker nib draws the flaps back into the sealed chamber configuration to protect the marker nib and cartridge from atmospheric degradation.

Abstract: A portable hand-held power stapler with an outer housing contoured to fit comfortably within the grip of a hand, said stapler having an improved actuation system comprising a manually operated power switch that will actuate the stapling mechanism when a paper-sensing arm positioned in a document insertion slot is brought into contact with the inserted edge of a document, thereby completing the electric circuit to the power source of the electric motor driving the stapling mechanism, said actuation system further having a manually actuated reverse switch to engage a reverse function of the stapling mechanism to clear a paper or staple jam.

Abstract: A capless retractable sealed marking instrument has a sealed chamber incorporated in a marker casing. The sealed chamber includes a chamber, a wiper ring, and an annular rim and a seal portion with a cross-slit aperture defining surfaces or flaps which are moved out of contact by a linearly-advanced marker nib to open the seal for extension of the marker nib. The configuration of the disk provides positive sealing force between the lateral sealing surfaces of the seal flaps. In the storage position, the seal effectively closes to protect and preserve the associated component. In a preferred embodiment, a housing member includes a closing member. The closing member engages the disc to seal the slit in the closed position when the associated component is in storage. The disc may include tabs that engage the closing member.

Abstract: A frame assembly supports a pair of rolls of clear plastic laminating tape. The two rolls of laminating tape are rotatably disposed facing the other, top and bottom, and dispense toward the center towards a stationary bar to the fore of the device. The frame is open to the rear and a rear feed guide is used to insert a web of cardstock or paper so that the inserted material is directed in between the convergent tape rolls so as to be adhesively secured on top and bottom to the laminating tape. The cardstock is advanced through the tape rolls by pulling the forward distal ends of the laminating rolls. A cutting bar that moves downward to meet the stationary bar. The web of stock and laminating tape form a laminated sheet that is cut off by applying downward pressure against the cutting bar on the stationary bar. A resistive heating element may be provided to cut the laminating tape thermally.
