Abstract: Platform assemblies may be built up using a substantial number of inverted U-shaped vertical supports with platform hold down members that hold the platforms in place, thus avoiding slippage or pilferage. The hold down members form a unitary structure with the supports and platform assemblies to hold the platforms securely in place. The unitary structure of the scaffolding assembly with hold down members acts as a deterrent against pilferage of the platforms because the unitary structure does not allow the planks to be removed unless the platform assembly is substantially disassembled. It also reduces the steps required to assemble a secure platform assembly with hold down members thus saving time while still preventing slippage and pilferage. The hold down members may have holes at one end, and these holes have a diameter slightly greater than the outer diameter (OD) of the guide pipes at the junctions between vertically extending pipes.

Abstract: A machineable envelope assembly includes an envelope and a strip releasably attached to the envelope. The strip extends out from the envelope flap when the strip lies flat relative to the envelope pocket panels to define with the panels a rectangle having a full letter-size paper width. Thus, when the assembly is in a paper tray of a printer or copier, the assembly is configured and sized to engage both sides of the paper tray, so that the envelope is continually aligned and does not skew during a feeding and printing process in the printer or copier. Thereby the address(es) and/or any PC printed postage are printed straight and accurately positioned in the envelope. The assemblies can be stacked into printer infeed trays and automatically fed therefrom for mass printings and mailings. And after being printed and output by the printer, the strips are peeled off of the envelopes, the paper sheet(s) or other desired contents inserted into the envelopes and the envelope flaps sealed closed.

Abstract: A pop-up structure or sticker for use with two hinged panels, includes a display area, and is provided with transparent supporting legs or other structure, secured to both of the two hinged panels so that the pop-up structure or sticker folds flat when the panels are closed and pops up and appears to "float" over the hinged panels when they are opened.

Abstract: A spa facility includes a pliable container, and flexible hoses for connecting to the pump and heater of a conventional pool, as well as to a source of compressed air. A flotation member is secured to the rim of the container. A plastic dome includes double tubes along its rim, one filled with air and the other with water, and is inflated by the pressurized air bubbling up out of the spa container. The pliable container is supported by pool water and/or a supplemental stiff supporting container.
