Abstract: A mixed mail processing machine comprising a series of modules for performing mail processing functions on the mail pieces as they are transported, oriented horizontally, along a feed deck bordered by a reference surface for registering the mail piece edges, the feed deck being tilted by an angle of 4.degree.-6.degree. off of a horizontal plane for utilizing the assistance of gravity forces to maintain the mail pieces registered.

Abstract: A window shade assembly is provided that includes a pair of independently movable shades, which are located in a front-to-back relationship. The front shade is made of a substantially translucent or light passing material while the back shade is made of a substantially opaque or light blocking material. The user of the window shade assembly is able to adjust one or both of the front and back shades to control where outside light is able to pass through the assembly including the amount of outside light that passes through the front shade or passes directly into the room without passing through the front shade.

Abstract: Singulating apparatus for singulating mail pieces of varying sizes and thickness comprises reversely-driven belts mounted in a four-bar linkage that pivots upwardly to allow bottom most mail pieces through while driving backward overlying mail pieces.

Abstract: A connector assembly for use in attaching a lanyard pull wire to the trigger of a powder-actuated tool which is mounted on a pole for overhead use. A tubular member, preferably a spring, receives a wire loop through its bore. The member slips onto the tool trigger, and the lanyard is connected to the wire loop. The connector assembly is thus easily removable and does not require extra tool modification to use.
