Abstract:
A closure having a stopping mechanism whereby a stop lug is positionable between a flexed and unflexed position relative to a spring gap. The stop lug may project from a skirt of the closure top wall. The spring gap is positioned adjacent the stop lug to provide an area for the stop lug to travel when outside forces are applied to the stop lug and subsequently return back to the unflexed position. The stop lug may have a substantially vertical support rib in combination with a plurality of annularly spaced ribs.
Abstract:
A pole bridle (20) for facilitating the manipulation of a pole (22) by a hoist includes plates (24) configured for placement in spaced-relation about the pole (22). Retaining members (26) are coupled to an outer surface (28) of the plates (24). The retaining members (26) are configured to retain a flexible member (62) of the hoist in encircling-relation about the pole (22). An upward force (72) imposed on the flexible member (62) creates a transverse force (74) on the plates (24) to direct the plates (24) against the pole (22). The transverse force (74) largely prevents the plates (24) from slipping along the pole (22) as the upward force (72) incrementally extracts the pole (22) from a fixed, upright position in the ground (60).
Abstract:
The present invention relates to a hydraulic speed control system for controlling the peripheral speed of a pick-up reel rotatively mounted about the front of a peanut combine. During the harvesting operation, the hydraulic speed control system is adapted to drive the pick-up reel at a generally constant speed as long as the ground speed of the peanut combine is equal to or less than a selected speed. The hydraulic control system is responsive to the ground speed of the peanut combine such that once the ground speed exceeds said selected speed, the hydraulic control system then drives the pick-up reel in proportion to ground speed such that the peripheral speed of the reel is generally equal the harvester ground speed in order that the relative velocity between the entering crop material being delivered to the combine by the reel and the combine itself is generally zero.

Abstract:
An electrographic liquid applicator head is inexpensively but precisely fabricated by adhering a flat base member, in which grooves are molded or cast, to a thin, photofabricated cover member. The adhesive isolates the supply gutters of the base and supply slits of the cover from adjacent drain slits and gutters. In a preferred embodiment the surface of the cover member is held in a suitably planar position by a planar surface on a magnetic chuck.
Abstract:
A pressure regulator system for providing controlled reduction of fluid pressure from a relatively high pressure fluid source to a relatively low regulated fluid pressure output. The pressure regulator includes a pressure reduction regulator designed for stable flow under transonic conditions, and an improved solenoid valve assembly for switching the reduction regulator to an operational condition.
Abstract:
A solenoid valve assembly including a movable armature acting through a lost motion unit for moving a valve member to an open position. The lost motion unit stores armature stroke energy during an initial stage of armature stroke, and sums the stored energy with armature stroke energy during a latter stage of armature stroke to open the valve member.
Abstract:
The present invention relates to an automatic tobacco harvester having a longitudinal leaf conveyor system for receiving tobacco leaf material defoliated by a defoliator assembly carried by said harvester and generally conveying the received leaf material rearwardly and upwardly about said harvester where the longitudinal conveyor system discharges the leaf material therefrom about a rearward elevated area on said harvester. The longitudinal leaf conveyor system of a particular harvester includes a series of laterally spaced longitudinal conveyor assemblies, each conveyor assembly including a horizontal conveyor section for conveying the leaf material from the defoliator assembly towards the rear of said harvester, and an elevating section which acts to convey the leaves from the horizontal section upwardly therefrom to an elevated area on said harvester where the leaves are discharged therefrom. The elevated section of each longitudinal conveyor assembly includes a pair of adjacently disposed endless leaf elevating conveyors that cooperate to convey tobacco leaves therebetween to the elevated area of discharge. The endless leaf elevating conveyors include a lower disposed wire chain type conveyor and an upper slightly flexible belt conveyor, the belt conveyor being trained around a lower roller that is movably mounted relative to the adjacent wire chain conveyor for allowing a leaf entry area defined therebetween to be varied in accordance with various masses and volumes of tobacco leaf material entering between said wire chain and belt elevating conveyors.
Abstract:
A burner control system for improving burner performance and efficiency. The system may determine fuel and air channel or manifold parameters. Determination of parameters may be performed with a sensor connected across the air and fuel channels. A signal from the sensor may control the parameters which in turn affect the amounts of fuel and air to the burner via a controller. Parameter control of the fuel and air in their respective channels may result in more accurate fuel and air ratio control. One or more flow restrictors in fuel and/or air bypass channels may further improve accuracy of the fuel and air ratio. The channels may be interconnected with a pressure or flow divider. Byproducts of combustion in the exhaust, temperatures of gas and air, flame quality and/or other items may be monitored and adjusted with control of the fuel and air ratio for optimum combustion in the burner.
