Abstract: A communication device (10) in a clam shaped housing includes a camera (12) incorporated within a first portion (18) of the clam-shaped housing and a lens (14) incorporated within a second portion (19) of the clam-shaped housing. The camera and the lens can substantially align when the first portion pivots relative to the second portion. The lens can be an afocal converter lens that changes an effective focal length of a lens of the camera from among a wide angle, a telephoto, and a macro lens. The communication device can have at least one among a main display (15) on a flip portion of the communication device or an auxiliary display (16) on an opposing side (21) to enable viewing without the lens when the communication device is an open position and the auxiliary display can enable viewing with the lens when the communication device is in a closed position.

Abstract: A stripper roller assembly employs first and second parallel spaced horizontally elongated rollers lying in a horizontal plane. A plurality of spaced horizontally elongated members are disposed at right angles to said rollers. Each member extends between and is secured to said rollers, each roller being freely rotatable about its horizontal axis in said members. A like plurality of horizontally elongated rack gear devices cooperate with the members. Each rack device is disposed adjacent a corresponding member intermediate said rollers and is horizontally slidable along the corresponding member between a first position at which the horizontal separation between the rack means are a selected one roller is a minimum and a second position at which said separation is a maximum. A horizontally elongated shaft is rotatably supported by the stationary main frame of the folding machine with which the assembly is used.

Abstract: An air operated electrically controlled machine using constant speed motors and known per se is provided with electronic counter and clock pulse generator control which eliminates uneven folding and over and under folding characteristics of the known machine and wherein separate photocell circuits control the folding operation while enabling much longer lengths of materials to be folded and eliminating jamming characteristics of the known machine.
