Abstract: PSA label constructions of this invention comprise a flexible substrate having a release surface, and a layer of pressure-sensitive adhesive disposed on the release surface. A nonblocking continuous film that, in combination with the pressure-sensitive adhesive is sufficiently self supporting, is disposed over a surface of the layer of pressure-sensitive adhesive to render the pressure-sensitive adhesive tack free. The continuous film is selected from the group of film-forming polymers consisting of polyamide resins, polyester resins, polyurethane resins, polyacrylate resins, vinyl acetate resins and mixtures thereof having a tensile strength of at least 200 psi, and a percent elongation of at least 50. The continuous film can be applied sequentially or simultaneously with the PSA. For purposes of simultaneous application it is desired that the continuous film be formed from a material having a hot melt viscosity that is within a factor of about two times a hot melt viscosity for the PSA. The completed PSA label construction is adapted to receive and retain printing or marking indicia directly onto a surface of the continuous film.

Abstract: A winch device, comprising a drum for storing cable and the like, wherein the device disengageably couples the drum to a winch drum shaft driven by a high torque, low speed hydraulic motor or pump.      The motor includes a housing suitable for mounting on a frame of a vehicle or other device. The principal components of the motor or pump include a crank shaft mounted in the housing for connection to a winch drum shaft. At least two cylinder and piston assemblies are attached to the crank shaft for rotation of the crank shaft upon movement of the pistons between a minimum and maximum point of travel in the cylinders to thereby impart motion to the crank shaft and, thus, the drum crank shaft. A valve assembly is driven by the crank shaft for providing hydraulic fluid to the cylinders under pressure to sequentially move each the piston between its minimum and maximum points of travel by providing hydraulic fluid under pressure on each face of the piston to move the piston in the desired direction of piston travel. The preferred coupling device is a driver block mounted on the crank shaft, a driver block receiving socket mounted on the winch drum shaft: and a unit moving one of the shafts into and out of engagement there between.      A brake prevents rotation of the winch drum shaft whets the shafts are out of engagement there between.
