Abstract: An object assembly device automatically assembles a collection of rolling objects of identical size and shape. The assembly device includes an assembly housing having an inlet for receiving rolling objects and an outlet through which the rolling objects are discharged. A rotary feed cone is rotatably mounted within the housing between the inlet and the outlet. The feed cone defines a single-line travel channel having an entrance end and an exit end. The width of the travel channel is sufficient to accommodate no more than a single line of rolling objects moving downstream in succession from the entrance end of the channel to the exit end. A stationary cone base is located within the collection housing, and has a conical interior wall adapted for receiving the rotary feed cone. The cone base has an object discharge opening operatively aligned with the exit end of the travel channel to allow passage of objects outwardly through the cone base in an assembled single-line condition.

Abstract: A object assembly device automatically assembles a collection of rolling objects of identical size and shape. The assembly device includes a collection hopper having an inlet for receiving rolling objects, and an outlet below the inlet for discharging rolling objects. An object assembler is rotatably mounted within the hopper between the inlet and the outlet. The assembler defines a single-line travel channel having an entrance end and an exit end, and a width sufficient to accommodate no more than a single line of rolling objects moving downstream in succession from the entrance end of the travel channel to the exit end. Objects entering the travel channel from the inlet of the hopper are discharged through the outlet of the hopper in an assembled single-line condition. A drive shaft is provided for rotating the object assembler relative to the collection hopper to avoid obstructing accumulation of rolling objects at the entrance end of the travel channel.

Abstract: A novel slide test element and method of making are described. Both feature a lip coined in the sidewall of a recess shaped in a frame member to hold the reaction member bearing the detecting reagents. The lip then overhangs the reaction member, once assembled. Assembly occurs by bending the frame member with the lip facing outwardly, thus forcing the lip to part a distance sufficient to allow the reaction member to be inserted. An optional stacking and fusing procedure is also described to facilitate shipment of frame members prior to assembly.
