Abstract: A kit for converting a fixed ramp rotating bowl feeder into a flexible disk, stationary ramp rotating bowl feeder including an overhead ramp support for spanning the distance between side walls of the rotating bowl. A retaining tube is affixed to substantially a central portion of the overhead ramp support. A stationary ramp is affixed to one end of the retaining tube and projecting outwardly toward the side walls of the rotating bowl. A flexible disk mounted on the stationary ramp for rotating within the rotating bowl together with the rotating bowl for transporting articles disposed within the bowl upwardly to be discharged therefrom.

Abstract: A rotating ring orienting feeder including a hopper for containing a supply of articles. A ring is positioned above the hopper. A support member is provided for retaining the ring in a substantially horizontal position. The supports also provide rotation for the ring. A conveyor is provided within the hopper for supplying articles to the ring. A drive mechanism is provided for imparting rotation to the ring and to the conveyor. A plurality of articles are supplied to the ring by the conveyor and are qualified on either side of the ring. Articles not being disposed in a predetermined orientation are returned to the hopper for resupply. In another embodiment, the articles positioned on the ring may also turn from one position into another position in order to qualify the articles directly on the ring.

Abstract: An article feeding appartus for supplying articles includes a base member with a side wall member having a first surface and a second surface. The first surface is secured to the base member. A rim member is secured to the second surface of the side wall member. An elevating turret is centrally disposed relative to the base member. A plurality of inclined ramp segments are operatively connected to the elevating turret and radially extend from the centrally disposed elevating turret towards the side wall member for forming a reservoir area into which articles may be supplied. A drive member is provided for rotating the base member, side wall member, rim and elevating turret at a predetermined speed.

Abstract: A rotary puck conveying, accumulating and qualifying mechanism for accommodating articles of various sizes. A puck is provided having a predetermined outer peripheral surface and including an article retaining aperture disposed therein. The article retaining aperture being of a predetermined shape for accommodating an outer peripheral surface of an article being handled. A centrifugal feeder is provided for supplying a plurality of articles to an outer peripheral rim. A rotating table accumulates the pucks in both a full and an empty condition. The rotating table is operatively disposed beneath the centrifugal feeder wherein outer peripheral surfaces of the centrifugal feeder and the rotating table overlap. A plurality of pockets are rotatably disposed below the centrifugal feeder for engaging pucks positioned on the rotating table for retaining the pucks in a predetermined location relative to the centrifugal feeder for supplying articles into the aperture in the puck over an extended length of transfer.

Abstract: Photography, particularly, a method of modifying slide transparencies so as to eliminate distortion and to provide uniform illumination in oblique projection, for example, upon rear view screens.The method of modifying slide transparencies includes supporting the object to be photographed at an angle with respect to the optical path of the camera; selectively illuminating the object to be photographed such that the portion farthest from the camera receives the greatest portion of the light with the rest of the object being gradually and continuously less illuminated so the portion nearest the camera receives the least light; and, taking a picture of the object, such that the transparency defines the object being photographed in trapezoidal form with the wider base being the least illuminated and the narrow apex being the greatest illuminated.
