Abstract: The embodiments shown provide a coupling apparatus and method of use to enable fluid communication between a multi-port mechanical switch and a primary dive regulator. The apparatus includes a grooved portion configured to be releasably attached to a multi-port mechanical switch and a leading edge dimensioned to be releasably secured onto a primary dive regulator. The method includes providing the apparatus with the multi-port mechanical switch and primary dive regulator and compressing or extending onto the first end into the multi-port mechanical switch, and extending a second end onto a primary dive regulator to create a hermetically sealed channel for fluid communication through the apparatus.

Abstract: The breathing port isolation apparatus includes a housing, valve, and actuator to enable a diver to isolate a breathing port of a snorkel or dive regulator using a single mouthpiece. The housing is configured to seat the valve and actuator and releasably engage a mouthpiece and dive regulator, which provides the diver with a continuous flow of air through the mouthpiece without having to transition between multiple regulators or breathing ports. The valve includes a piston and enables linear movement between the first and second port. The actuator enables the diver to depress a push-button and transition the actuator between depressed and extended positions, which correspond to the first and second breathing ports.

Abstract: A stack of sheets bound on one end and supported by a backing sheet with dimensions of at least 25.5 by 33 inches. Individual sheets are removed from the bound stack of sheets with a horizontal microperfed line. Further, each sheet can be divided into nine 8.5 by 11 inch subsections using lines of weakening within the paper sheet whereby each 8.5 by 11 inch subsection can be easily folded or loaded into a copier, printer, scanner or shredder.

Abstract: A business card assembly for printing on with a desktop printer. The card assembly having two printable sides, and microperfs for defining business card subsections. Further each subsection has a first portion and a second portion. The first portion contains a tab for releasably attaching the business card first portion to the second portion.

Abstract: An image transfer assembly (12) receives an image printed from an ink jet printer. The assembly (12) provides a device to transfer the printed image onto an image-receiving surface. The assembly (12) has a flexible substrate (16) on one side, and an upper surface (20) on the other side that is substantially permeable to ink jet printer ink and that is non-tacky prior to printing. The assembly (12) has an adhesive or polymer layer (14) in between the upper surface (20) and the flexible substrate (16). After printing with a water-based ink jet printer ink, the user may apply the assembly (12) to a substrate, such as a window or other surface, and remove the flexible substrate (16), thereby leaving the layer (14) that bears the image on the substrate. In one of several alternative embodiments, the layer (14) is divided into discrete zones that are separated from one another along boundaries.

Abstract: Generally speaking, a method for forming custom-printed, three dimensional structures using a computer and a computer-controlled printer, has several steps. A flexible rectangular sheet is perforated to form a removable portion. Lines of weakness are formed on the removable portion, to serve as fold lines that ultimately folding the two-dimensional removable portion into a three-dimensional structure. A user instructs a computer program to command a computer-controlled printer to print particular information onto the printing surface of said removable portion. After printing, the user removes the removable portion from the sheet along the perforations and then folds the removable portion along the lines of weakness and secures the folded sheet into a three dimensional structure. The removable portion may be provided with a pressure-sensitive, water-activated, cohesive or other type of adhesive for adhering securing the folded sheet into the three-dimensional structure.

Abstract: A system for rivetless attachment of a ring binder assembly to a cover wherein an attachment portion including one or more prongs adapted to imbeddingly engage a cover substrate and a surface adapted to mate in facing relation with a surface of the cover is formed unitary with a confining spring cover plate of the ring binder assembly, the ring binder assembly being attached to the cover by forcing the attachment portion against it with sufficient force to drive the prongs into the substrate and hold the surface of the attachment portion firmly against the cover.

Abstract: Image-recording technology records images displayed on a screen onto an image sheet. An image-recording assembly has an image sheet and an associated opaque shield. The shield is slidable to expose the image sheet to the image displayed on the screen. The image sheet may be of the type which has microcapsules containing photo-hardenable chemicals coated onto a base sheet. The image-recording assembly is positioned in front of a screen displaying an image with a user exposing the image sheet by shiffing the position of the shield. The exposure time may be controlled manually by the user or automatically by software displaying the image on the screen. To develop the image sheet, unexposed microcapsules are ruptured by either applying pressure to the image sheet or forcefully sliding the image sheet across a sharp edge. The image-recording assembly may be flexible and is preferably less than 15 mils thick.
