Abstract: A pressure sensitive adhesive membrane and its cooperating, protective, underlying coated release paper are provided with retaining means and the membrane and paper layer are then formed into and maintained as a substantially cylindrical, rolled configuration, creating a unique easily handled, readily employable membrane dispensing assembly. In one embodiment, the retaining means comprises an adhesive which is applied to the non-release coated surface of the paper layer, thereby assuring maintenance of the rolled configuration while enhancing the deployability and the efficacy of the membrane. In another embodiment, a retaining band is affixed about the cylindrical, rolled pressure sensitive adhesive membrane in order to maintain the membrane in the desired rolled configuration.

Abstract: A pressure sensitive adhesive membrane and its cooperating, protective, underlying coated release paper are provided with adhesive means and the membrane and paper layer are then formed into and maintained as a substantially cylindrical, rolled configuration, creating a unique easily handled, readily employable membrane dispensing assembly. In the preferred embodiment, the adhesive means is applied to the non-release coated surface of the paper layer, thereby assuring maintenance of the rolled configuration while enhancing the deployability and the efficacy of the membrane.

Abstract: Apparatus which simulates the exercise obtained while climbing stairs includes two hydraulically phased steps retained in adjacent inclined tracks in which the steps are supported in a hydraulically open-ended system, with the phasing of the steps being controlled by a pair of in-line hydraulic actuators, one each associated with a step, in which fluid forced from one actuator with a downward movement of the associated step is channeled through a variable restricted orifice to the other actuator to raise the other step. In one lightweight, compact embodiment, the device is collapsed down to a compact size through the use of steps which are foldable to the track, and through the use of a track foldable to the frame. In its open position the lower portion of the frame props up the track at an appropriate climbing angle, with upper portions of the frame extending above the track to serve as handles positioned above the center of travel of the steps.
