Abstract: Masking film stacks, kits composed of said film stacks, adhesive tapes, and covering tapes, and methods for producing said stacks and kits are provided. The masking film stacks comprise masking films having widths and lengths, wherein the masking films are foldable along folding lines, running along the lengths, to form double-ply-folded masking films such that two free longitudinal edges of the double-ply-folded masking films run adjacent to each another and the double-ply masking films are foldable to form stacks and the two longitudinal edges lie on the masking film stacks.

Abstract: An anterior cruciate ligament or soft tissue tensioning and knee displacement measuring device and method for its use to apply a tensile stress into a repaired or replaced graft and to maintain tension on that graft while an interference screw, or like fastener, is turned into a tunnel section end, containing the graft or sutures connected to the graft, wedging it against the tunnel wall, and, during application of the tensile stress, for determining the distance that the knee is displaced. The invention includes a tensioning device having, as a body, a pair of straight rails with a cross member secured across the rails rear or distal ends with forward or proximal rail ends connected to mounting tubes that are for fitting into pins as have been mounted into to extend from a bone cortex, alongside the tunnel section end, and including a trolley maintained to travel between the body rails.

Abstract: A programmable timer for turning a light on and off in response to changing sunset, daylight savings time, and other programmable conditions. The programmable timer includes an input device, a microprocessor, and a switch. The input device provides calendar, geographical, and daylight savings information to the microprocessor, which stores the programming information. The microprocessor computes an effective switching time from the stored information. The microprocessor employs program logic that compares the effective switching time to the current time to generate a timing control signal. The timing control signal, in turn, causes the switch to turn a light on and off. In the preferred embodiment, the microprocessor and the switch are included within a housing which mounts on a wall in place of a normal light switch. A liquid crystal display is disposed on a face of the housing to provide a read out of the programming information and of the time of day.
