Abstract: The present invention provides a saddle-less fitting having a stepped outer wall surface. The stepped outer wall surface includes a first and second surface and a step. The step includes a first bowed band surface extending from the first outer wall surface a predetermined distance inward towards the inner wall surface. The fitting further includes an insertion portion which includes the second outer wall surface and a second bowed band surface. The first bowed band surface and the second surface are bonded to a prepared pipe with a bonding agent. A more liberal application of the bonding agent may be employed to cause the other fitting and pipe surfaces to further bond together. Once the bonding agent hardens, or becomes cured, a unitary structure is formed which provides a leak-free tap.

Abstract: Reduction of reflection from an integrated circuit substrate during exposure of a photoresist layer on a surface such as an integrated circuit wafer is minimized by incorporating an antireflective coating between the photoresist layer and the integrated circuit substrate. The antireflective layer, after exposure and development of the photoresist layer, is preferably removed by exposing the non-masked antireflective layer to activating radiation while heating the coating to induce a solubilizing reaction in an antireflective coating and a curing reaction in an overlying photoresist mask. Thereafter, the exposed portions of the antireflective layer are removed by treatment with a suitable developer.

Abstract: A lift system for individually elevating one or more harvesting units of a cotton harvester through a range of movement extending between an operational position and a raised position while maintaining other harvesting units in an operational position relative to the harvester. The lift system includes a source of actuating fluid, a fluid pressure actuator connected to each harvesting unit for elevating a respective harvesting unit, and a control system connected between the source of actuating fluid and each fluid pressure actuator for selectively controlling the elevation of the harvesting units relative to the chassis of the harvester. The control system includes ground sensors for individually maintaining the harvesting units in a preselected elevational position relative to the harvester.

Abstract: A discharge conveyor system for a cotton harvester which removes a commingled mixture of ripe and green bolls from cotton plants during a harvesting operation. The discharge conveying system includes duct structure having an inlet arranged proximate to an outlet on a harvesting head assembly from which the commingled mixture of harvested materials pass. An air system directs an air stream through the duct structure such that ripe or lighter bolls are drawn into the duct structure while heavier or green bolls fall from the outlet of the harvesting head assembly. A basket is mounted on the harvester for receiving the green bolls and includes a floor comprised of a plurality of louvers which combine with each other, in one position, to hold green bolls in the basket, and are movable to a second position wherein the louvers are arranged relative to each other for purposes of boll discharge.

Abstract: A hydraulic drive system for driving component parts such as harvesting units of a cotton harvester head assembly. The hydraulic drive system includes a source of actuating fluid and fluid pressure actuators for driving the harvesting units independently of each other. Suitable conduit structure connects each fluid pressure actuator to the source of actuating fluid. The conduit structure is preferably flexible to facilitate transverse positioning of the harvesting units on the head assembly. A control valve assembly is connected to the conduit structure and is operably interposed between the source of actuating fluid and the fluid pressure actuators for selectively interrupting and effectuating the supply of actuating fluid from the source of actuating fluid and each of the fluid pressure actuators thereby influencing operation of the harvesting units.

Abstract: The adjacent edges for two covers of a tote box have interlocking fingers where separation is resisted by means of hooks on one or more of the covers engaging side flanges of the box to lock the covers in place. The closed covers present a flat surface inset with respect to a plurality of abutments in the vicinity of the sides and ends that prevent side shifting of a like box stacked on top of it. The side abutments have a second function of latching into the end walls to hold the covers in their open position, even when a plurality of like boxes are nested. The latches and locks are unitarily molded into the cover and provided with cam surfaces that together with inherent resiliency of the structure provide for locking and latching by movement of the cover.

Abstract: A shelf for an order picking system includes a rectangular frame having front and rear rails with upwardly facing bottom support surfaces and uniformly spaced notches along the length thereof above the support surfaces. Track members extending across the frame between the rails have bottom end portions supported on the support surfaces and have end edge portions received in certain of the notches. The track members are selectively adjustable to different positions by placing the track member end edges in different notches.

Abstract: A track member having a bottom end portion resting on an upper surface of a support flange has a clip member slidably attached thereto for movement between a locking position and a releasing position for respectively preventing or permitting upward movement of the rail end portion with respect to the support flange. In the locking position of the clip member, a projecting tongue engages the bottom surface of the support flange opposite from the upper surface area on which the track member bottom end portion is supported. In the releasing position of the clip member, the tongue is clear of the support flange.
