Abstract: A portable apparatus and related method for practicing tennis, comprising: a frame substantially fixed in a substantially vertical orientation; and a mesh mounted to the frame, disposed in a substantially vertical plane, and pulled taut in relation to the frame to a user-determined tension; wherein: the structural combination of the frame, the mesh and the tension of the mesh in relation to the frame enables a tennis ball striking against the mesh to rebound from the mesh in the manner of a trampoline rebound; whereby: a user of the apparatus can practice tennis, alone, in any environment, with minimal noise, by hitting the tennis ball into the mesh, and thereafter successively hitting rebounds from the mesh back into the mesh, at will. This enables a person to practice tennis, alone, in any environment, with minimal noise, at will.

Abstract: A paper roll dispensing apparatus in accordance with the invention comprises outer winding separation and inner winding restraint means for restraining inner windings of the paper roll from unrolling while simultaneously separating an outer winding of said paper roll from its inwardly-adjacent winding, and tension-supplying means for pressing a restraining edge of the outer winding separation and inner winding restraint means against an outside layer of the paper roll, both when the paper roll is substantially full and as the paper roll becomes depleted. Preferably, the paper roll also comprises tack adhesive means for adhering successive windings of the paper roll to one another when the outer winding is not pulled away from its inwardly-adjacent winding and simultaneously enabling the adhesion to be broken without substantial tearing of the paper when the outer winding is pulled away from its inwardly-adjacent winding.
