Abstract: A mail decelerating device wherein a straight channel with a V-shaped cross section is supplied by a conveyor channel with a number of mail items; the mail item is intercepted and directed by a deflecting element towards an inclined wall of the V-section channel, along which it slides and is arrested on striking a kinetic energy dissipating device at one end of the V-section channel; following stoppage of the item, a bottom opening in the V-section channel is opened, and through which the mail item drops out by force of gravity.

Abstract: A batter board is interposed between an upper conveyor belt, that is discharging granular material, and a lower conveyor belt that is receiving it. The batter board is adapted to deflect the downwardly arching stream of material, to laterally adjust the location on the lower belt where the material is deposited. The extent of deflection practised is controlled in response to measurements which monitor the downstream belt side travel of the lower belt. The position of the batter board is adjusted with hydraulic actuators protected with a shock absorbing system.

Abstract: A method of and apparatus that is continuously automatically operative in an in-line system is described for applying under heat, vacuum and mechanical pressure a photoresist-forming layer to printed circuit boards that already have been prelaminated by the loose application thereto of dry film as discrete cut sheets within the confines of the surface of the boards whereby a laminate without entrapped air bubbles and closely conforming to the surface contours such as circuit traces of the printed circuit board is obtained. Featured is a two-part conveyorized vacuum applicator comprising as one part two input conveyors in end-to-end relation and as the other part a belt conveyor and vacuum laminator.

The impact plugs may be formed in various shapes to resist becoming dislodged from the polyurethane bed.

Abstract: Apparatus for loading friable nuclear fuel pellets into a sintering boat from a pellet press which ejects newly made pellets. An inclined pellet chute (preferably a tube) receives the ejected pellets and discharges them against a first resilient brush which reflects the pellets downwardly to a second resilient brush. The brush tips are spaced apart such that a pellet moving downward along the second brush contacts the flexible brush tip of the first brush before dropping off the second brush (preferably with near-zero velocity) into the sintering boat.

Abstract: An automatic combinatorial weighing apparatus includes a double collection chute assembly disposed in delivery paths for passage of articles to be weighed. The double collection chute assembly includes an inner collection chute having an outlet and a pair of outer collection chutes having respective outlets, the outlets being connected to timing hoppers, respectively. Articles flow down the inner and outer collection chutes at as equal speeds and in as equal times as possible, the speeds being increased as much as possible, due to valleys created by flat plates which form the chutes. To prevent an increase in noise produced by hitting engagement of the articles with the chutes as the articles flow down the chutes at high speeds, a vibration damper having a vibration-restriction damping capability is disposed in an area of the delivery paths for damping the vibration to suppress the noise.

Abstract: A transfer assembly of a belt conveyor comprises a discharge drum of the conveyor rigidly secured on a frame at the discharge end of the conveyor. Also on the discharge end of the conveyor is hinged a deflector shield which has a curvilinear portion whose concavity faces the discharge drum and is located after the drum along the conveyor belt movement. The shield has an entry portion located before the discharge drum along the conveyor belt movement. A support is secured rigidly to the frame at the discharge end of the conveyor. Two rods are hinged by first ends to the support, the rods being positioned one after the other along the conveyor belt. The other ends of the rods are hinged to the shield so that the distance between the first ends does not exceed the distance between the other ends of the rods.

Abstract: A first transporting unit advances a series of stacks of paper sheets along a straight first path. A transfer conveyor can be lifted into the first path to divert selected stacks into the range of a second transporting unit which defines a second path making an oblique angle with the first path. The transfer conveyor is assisted by a pusher which is adjacent to the first path opposite the stack-receiving end of the second transporting unit and is movable at right angles to the first path to move the diverted stack sideways. Such stack strikes a yieldable bumper which expels it from the second path into the range of a third transporting unit serving to advance stacks in parallelism with or at right angles to the direction of movement of stacks along the first path. The orientation of selected stacks remains unchanged during diversion from the first into the second path as well as during diversion from the second into the third path.

Abstract: Apparatus for preventing segregation of aggregate includes a plurality of vertically disposed chutes at the discharge end of a conveyor, each chute being arranged to intercept a portion of aggregate leaving the conveyor, and direct it downwardly onto a common pile.

Abstract: An improved conveyor system for transporting die-cut blanks from a rotary die cutter to a blank stacking device includes a blank take-up section comprising a spring biased take-up guide which insures that blanks are positively engaged by the conveyor system before they are released by the die cutter. The conveyor system includes a vacuum belt which serves to suspend and transport die-cut blanks while maintaining them in precise registry to a blank stacking device. An improved snubbing device is disclosed which decelerates blanks without damage to the blanks themselves and then causes the decelerated blanks to rebound back toward the die cutter for improved stacking. A ramp structure is disclosed which flexes blanks near the blank release section of the conveyor system such that the trailing edge of transported blanks snap away from the conveyor system, thereby positively disengaging the blanks from the conveyor.
