Abstract: The piston of a pneumatic cylinder is reciprocated with a controllable dwell time at each end of its stroke, under the control of a digital fluidic circuit which responds to the termination of exhaust flow at the end of each piston stroke to initiate the reverse piston stroke. The air for driving the piston is supplied alternately to opposite ends of the piston through respective cylinder ports, by way of a corresponding pair of pilot valves which are controlled by the fluidic circuit so that one or the other of the pilot valves may supply driving air to the piston at any time.

Abstract: Apparatus is provided for supporting load bearing, sharply curved girders, particularly for use in a transportation system. The sharply curved girders are supported only at their ends, even for those of substantial length, so as to reduce the number of vertical supports for the girders. This is achieved by providing a relatively short cross-support for the girder extending from the vertical support through the girder at each end thereof, with that cross-support or console having one end bearing on the vertical support and the other end forming a portion of a pivot bearing positioned on the inside of the curve of the girder. A crossbeam rigidly connected to the vertical support also extends transversely of each girder end and forms the opposite portion of the pivot bearing. Thus, torsional forces tending to twist the outside of the curve of the girder downwardly under load is compensated by the pivot bearing which provides a twisting force in the opposite direction.

Abstract: The disclosure is directed to automatic bobbin rewinding for sewing machines. A two-station mechanism is provided enabling bobbins to be transferred from a winding position to a sewing position, with one bobbin being at all times in each position. When a bobbin is exhausted, that bobbin and its case are removed from the sewing machine and, simultaneously, a filled bobbin is removed from the winding position and combined with its case. The bobbin positions are then reversed, enabling the filled bobbin and its case to be inserted in the sewing machine, while the just-removed bobbin is separated from its case and inserted in the winding position. The filled bobbin remains attached to the main thread supply until it is inserted in the sewing position, enabling the thread to be guided and controlled until picked up by the sewing mechanism, thus avoiding the need for manual intervention.

Abstract: Insects are collected and fed to aquatic animals such as fish and frogs. In collecting the insects, an ultraviolet lamp for attracting the insects is hidden in a vertical funnel where the insects cannot see the lamp from a horizontal position. However, the lamp is open to view from above. The insects therefore must fly downwardly to reach the lamp. The lamp is positioned near the exit of the funnel, and the exit empties into an enclosed air space above the water containing the aquatic animals to be fed. A fan is located below the lamp to draw air downwardly through the funnel and into the enclosure below. The insects thus are urged into the trap by at least three forces: the force of gravity, inertia of the downwardly-flying insects, and the air drafts created by the fan. The funnel inlet makes a big target for the insects. Light is reflected upwardly by the funnel walls to attract airborne insects.
