An adjustable safety utility knife includes an elongated ergonomically shaped handle formed of two elongate shell members each having a peripheral edge and an outer generally convex surface and an inner generally concave surface. The shell members are fastened at the peripheral edges along a vertical parting plane to form an elongated internal cavity. The handle defines a front end, a back end and an intermediate portion suitable for being gripped by a user and also defining top and bottom surfaces extending along opposite sides of the shell members along said peripheral edges. The handle has a slot-like aperture at the front end substantially aligned with the parting plane and dimensioned for passage of a flat cutting blade therethrough. A guide element within the elongated cavity guides the cutting blade between a first position for safely storing the blade fully inside said cavity and a second position for selectively extending the blade beyond the aperture to expose at least a portion thereof. A manually operated button arranged on the top surface is coupled to the guide element for selectively moving the blade between the first and second positions. The handle has a rear opening at the back end for providing access to the elongated internal cavity. A carrier frame has a blade cartridge receiving compartment and dimensioned to be removably receivable within the cavity through the rear opening between a retracted position in which the carrier frame is fully stored within the internal cavity of the handle end and an extended position in which the carrier frame is at least partially moved exteriorly of the back end to provide access of the cartridge receiving compartment. A blade cartridge for storing a plurality of flat cutting blades is receivable within the blade cartridge receiving compartment.

It involves the use of voltage disconnect devices to rapidly, manually or automatically disconnect and isolate the vehicle energy storage devices from the electrical system of the vehicle with ease and safety. The electrical power source may be a battery, a battery pack, a capacitor or other device which may be used to store electrical energy onboard a vehicle.

A microwave cooking oven return of a food item to an original placement parking of the oven's rotating table concurrent with the end of a selected cook-time. The cooked foodstuff ends-up parked at the same frontward facing turntable orientation that existed at the onset of the oven's overall operating cycle by synchronizing overall turntable circumrotation time with a preferred cook time. This absolute concurrency of return-parking and selected cook-time completion safely provides for unencumbered open-door access enabling immediate removal of the foodstuff from the turntable at the very moment of cooking completion.

A polishing pad for planarizing and polishing a semiconductor substrate. The polishing pad (22) includes an adhesive layer (34) that is operative to adhere the polishing pad to a polishing fixture. To protect the adhesive layer from contamination during storage and shipment, a release liner (24) is placed over the adhesive layer. The release liner has sufficient surface characteristics to stay in adhesive connection with the adhesive layer during storage and shipment; however, the release liner is operative to be peeled away from the adhesive layer without disturbing the bond between the polishing pad and the adhesive layer. To aid in the removal of the release liner from the polishing pad, the release liner includes a pull tab (26). The pull tab is comprised of a single-sided tape that is adhered to the outer surface of the release liner. A portion (28) of the pull tab extends beyond the edge of the release liner. This extending portion has sufficient length to enable an operator of the polishing fixture to remove the release liner from the polishing pad while wearing gloves.
