Abstract: A backup power supply includes a housing with a central compartment holding an electrical generator preferably an alternator and a hydrocarbon powered motor. The housing further includes first and second side compartments. The first side compartment stores the electronic components of the generator. A top covers all three compartments and has two side overhangs and a forward overhang. The side overhangs provide air inlets to the two side compartments which in turn permit passage of air into the central compartment. The forward overhang includes an air outlet which allows air to be directed from the central compartment to outside the housing. The alternator itself includes a fan which pulls air from one side compartment into the central compartment. The motor has a second fan that pulls air into the central compartment from the second side compartment. Further the exhaust from the motor is encased in a shroud which leads directly to a passage through the top to the forward outside opening.

Abstract: An improved micro computer diskette is constructed from a light-weight, foldable paperboard blank having nonwoven liner material bonded on its inner surfaces. The paperboard blank is scored with double score lines to form a hinged portion between diskette jacket halves as a leading edge of the diskette and three side edges with overlay flaps for securing the jacket halves together. Folding the paperboard blank along the double score lines and adhesively securing the overlay flaps produces a rigid cartridge structure for diskette use having liner material on its inner surfaces and external surfaces adapted for printing thereon with any desired graphics. The paperboard jacket halves are embossed in corresponding sections with offset ridges for lifting the liner material into cleaning contact with the disk media. Head slots are punched in the paperboard blank, and an externally removable tab with self-adhesive edges is used to cover the head slots.

Abstract: An improved micro computer diskette is constructed from a light-weight, foldable paperboard blank having nonwoven liner material bonded on its inner surfaces. The paperboard blank is scored with double or heavy caliber, single score lines to form a hinged portion between diskette jacket halves as a leading edge of the diskette and three side edges with overlay flaps for securing the jacket halves together. Folding the paperboard blank along the score lines and adhesively securing the overlay flaps produces a rigid cartridge structure for diskette use having liner material on its inner surfaces and external surfaces adapted for printing thereon with any desired graphics. The paperboard jacket halves are embossed in corresponding sections with offset ridges for lifting the liner material into cleaning contact with the disk media. Head slots are punched in the paperboard blank, and an externally removable tab with self-adhesive edges is used to cover the head slots.

Abstract: An apparatus and method for manufacturing partially cut (semi-converted) products in continuous roll form has input feeds for supplying a continuous web of material and a continuous transport web in parallel, feed rollers for incrementally advancing the two webs together to a cutting station where product units are partially cut in successive increments in a continuous strip, a scrap remover, and a station for winding up the cut product strip. The webs are unwound and the cut product strip is wound via dancer bars maintaining constant tension. The input webs have a width which is a multiple of the width of the product units so that multiple strips can be formed simultaneously. The invention is used to form semi-converted, micro diskette liners having connecting portions and indented cutouts marking the boundaries between units. The cutouts are overcut in one direction and also in an intersecting direction to obtain complete cuts despite slight variations in registration.
