Abstract: An improved lid mechanism for a web feed device, particularly device for feeding perforated paper webs in printers, copiers and the like, and more particularly a tractor with an improved lid mechanism, wherein pins on which the lid (10) is pivotally mounted for movement between open and closed position are unloaded (do not have any force or bias applied thereto) when the lid is in its open and closed position. The lid (10), when closed, covers the paper and is then spaced from the surface (34,36) of a frame along which the paper is fed by a pin drive such as a belt (26) having pins (28) which extend into perforations of the paper (30). A depending leg (48) of the lid has a block (60) with surfaces (70,72) disposed at an angle (72) to each other. These surfaces extend from a corner (74) of the block. One of these surfaces (70) is preferably perpendicular to the surface (38) of the lid which defines the gap. The other of these surfaces (72) defines the position of the lid in its open position. These surfaces bear against the outer wall (56) of a side plate (16) of the frame of the device (the tractor) and are biased thereagainst by a flat spring (82) mounted on the side plate (16). This spring (82) bears against surfaces of said block opposite to the surfaces which bear against the outer side wall. The location of the lower surface (38) of the lid and the size of the gap (40) is defined by a pin and slot (76) hinge arrangement. The slot is longer (76) than the stroke of the pin which is executed as the lid moves between its open and closed position. Accordingly in both the open and closed position the block is under compression and the pin is unloaded. The lid may be molded and an integral body of plastic. The use of steel pins may be avoided. The location of the lid and the size of the gap is accurately defined since dynamic factors such as material strength, bending deflections and part homogeneity do not affect the accuracy of the lid position; the position being dependent only on the static dimensions of the block, the pin and the groove.

Abstract: An image of a subject in a scene formed by a fixed focus lens through a scanning aperture of an electronic flash camera, particularly that of a subject located closer to the lens than the near distance of its lens normal depth of field, has its clarity or sharpness substantially improved by firing the electronic flash during exposure at the smallest possible aperture for optimum subject image sharpness and overall scene exposure. The appropriate aperture to produce such an image is a function of ambient scene brightness and of the IR light from the electronic flash being reflected from a subject within the scene which are determined prior to and/or at the early stages of an exposure interval.

Abstract: This invention relates to barrier seal systems (10) for sealing the annular space between a housing (14) and a rotating shaft (12) which extends through a bore (16) in the housing (14). The seal system (10) has inboard (66) and outboard (46) mechanical end face seals. The inboard seal (66) faces have spiral grooves (98) for pumping a buffer fluid from a buffer chamber (68) between the two seals (46-66) toward the high pressure side of the inboard seal (66). The primary ring (76) of the inboard seal (66) may be double balanced. For high pressure applications, the buffer fluid may be pressurized and a pumping ring may be included in the outboard seal to circulate buffer fluid. High pressure applications also require two hard seal rings and optimum dam (100) and face widths. Buffer fluid can be supplied to the seal system by a reservoir (30) connected by a gravity feed line (108-112). A buffer fluid containment device may be attached to the high pressure side of the seal (10) to prevent process fluid from contaminating the seal faces or secondary seals.

Abstract: A hydrometallurgical method comprising a leaching operation is provided for recovering copper from particulate copper sulfide flotation concentrate containing at least about 20% copper by weight, a significant portion of the copper in the copper sulfide concentrate being in the cuprous state. The copper sulfide flotation concentrate in the finely divided state is subjected to leaching with an alkaline solution of ammonia plus ammonium sulfate of concentration ranging from about 30 gpl to 150 gpl of ammonia and about 25 gpl to 200 gpl of ammonium sulfate at a temperature ranging from about 10 DEG C to 95 DEG C, preferably about 20 DEG C to 40 DEG C, the amount of sulfide concentrate in the leaching solution ranging from about 25 gpl to 500 gpl proportioned at least stoichiometrically to the ammonia concentration of the leaching solution. The sulfide concentrate is leached under substantially ambient pressure while continuously aerating the solution for a time at least sufficient to dissolve the cuprous copper and oxidize it to the cupric state while avoid or substantially minimizing the oxidation of sulfide sulfur to sulfate, and thereby obtain a filtrate containing at least about 15% of the total amount of copper in the concentrate and provide a washed residue containing at least about 20% copper by weight comprised substantially of cupric sulfide. The copper in the leaching solution after further processing is subsequently recovered by electrowinning. The residue can be further treated in a smelter to recover copper therefrom or upgraded by subjecting the residue to conventional flotation and provide a secondary flotation concentrate containing at least about 30% by weight of copper. <IMAGE>
