  • Patent number: 5615995
    Abstract: A mail piece stacking machine is disclosed which is designed for use on conjunction with a mail piece processing or handling machine, such as a typical mailing machine, for stacking a plurality of pieces of mail as they are ejected seriatim from an outlet end of the processing or handling machine. The stacking machine has an elongate frame with a first feeding device consisting of a pair of cooperating rollers disposed adjacent the inlet end of the stacking machine, receives the mail pieces seriatim from the processing or handling machine and positively feeds the mail pieces into the stacking machine.

  • Patent number: 5577278
    Abstract: By providing position control means cooperatively associated with a support pad with said control means being constructed for arcuately moving the support pad in response to activation by the user, with the position control means and pad peripherally surrounded by a cover, a unique, portable, self-contained, unitary, movably adjustable support assembly is attained whereby individuals are able to position the support pad in any desired location or on any surface while also being able to automatically raise and/or lower the support pad to any position for comfort and support. In the preferred embodiment, the movably adjustable support assembly is constructed with expandable shroud means integrally connected with the cover in association with the position control means for expanding in response to the arcuate movement of the position control means while being automatically retracted into a folded configuration when the control means are returned to its original position.

  • Patent number: 5503388
    Abstract: A buffered stacking apparatus selectively diverts horizontally disposed documents from a main conveying path, then stacks and transports the documents to replaceable receiving receptacles. The apparatus has a primary horizontal conveyor belt with a lower reach defining a horizontal primary conveying path and at least one secondary conveyor belt having an upper reach which, when the secondary conveyor belt is in a horizontal position, is disposed in a lower juxtaposed relation to the lower reach of the primary conveying belt. The buffered stacking system also selectively effects pivotal movement of the secondary conveyor belt from the horizontal position to a second inclined position wherein the reach of the secondary belt is inclined to the lower reach of the primary conveyor belt. Documents being transported along the primary conveying path are diverted along the inclined reach when the secondary conveying belt is inclined.

  • Patent number: 5438874
    Abstract: By providing a captured roller construction as the movement assembly for a sensing element, a low cost, accurate, measuring instrument is achieved. In the present invention, the movement of the sensing element causes the movement assembly to produce rotational motion in direct response thereto. As a result, any change in the level of the source condition being monitored is immediately indicated on a visual readout, due to the responsive rotational motion of the movement assembly. By employing captured rollers as the principal means for attaining rotational motion, an easily constructed, dependable, low cost movement assembly and measuring instrument construction is realized.

  • Patent number: 5248960
    Abstract: By providing a pointer assembly which is easily mounted to a computer terminal or screen and is movable from a first position to any second position on the terminal or screen, with the position of the pointer being precisely measured and transmitted to the computer, a unique, easily employed signal generating and position controlling system is realized. By incorporating a switch in the pointer assembly or in association with the pointer assembly, any individual is capable of employing the system of this invention quickly, easily, and accurately, without requiring training or expertise. In the preferred embodiment, the pointer assembly is movable both arcuately and longitudinally, relative to a fixed initial position, with any movement from the initial position being precisely measured to determine the desired, user-selected position.

  • Patent number: 4300710
    Abstract: A continuous fan-folded form feeder is applied to a copying machine and has a receiver for the folded form from which the form is trained over the top of the copying machine platen and then beneath the platen to the rear of the copying machine for engagement by form tractors to be progressively fed in stages beneath the platen to a re-fold tray. Drive means for the tractors feeds the form step-by-step in selected increments of length.
