  • Patent number: 4247048
    Abstract: A two-piece nozzle for use on hand actuated pump dispensers is disclosed. The nozzle features a tubular member, which may be a part of the main body of the pump, having a circular, planar face at its terminal end. A hollow bore extending through the tubular member and the hollow face is in liquid passage communication with a recess in the planar face. A cap is rotatably mounted to the tubular member and has an end wall with a planar inside surface which will form an interface with the circular planar face of the tubular member. Radially displaced from the center axis of the circular skirt is a dispensing orifice which is registerable with the recess present in the planar face of the tubular member. A sealing boss surrounds the dispensing orifice and bore to provide a liquid-tight seal with the planar face when the orifice is not in registration with the recess. Mounting structure is provided on the cap and tubular member for achieving a rotating mount of the cap to the tubular member.

  • Patent number: 3984096
    Abstract: A method and apparatus for feeding letters from a relatively loose stack of letters, in which each successive end letter in the stack is subjected to repeated impulses applied by a rapidly reciprocating friction surface which moves in a direction having components of movement both transverse to and parallel to the plane of the end letter. The movement is sufficiently rapid that the inertia of the leading letter to movement transverse to its plane substantially increases the pressure between the friction surface and the leading letter as compared with the pressure between that letter and the next in the stack. The friction surface is preferably a relatively uncompressible pad which is moved with an elliptical motion to repeatedly strike the end letter at a speed between 1,000 and 10,000 cycles per minute.

  • Patent number: 3984158
    Abstract: The journal and/or pilot bearings of a rotary cone earth boring bit are constructed to include alternating areas of wear resistant materials and anti-galling materials. The bearing matrix is formed by compressing a powdered alloy in the shape of the desired bearing element. The bearing matrix is sintered, thereby forming a porous bearing element. An anti-galling material is infiltrated into the porous matrix of the bearing element and the bearing element is hardened. The resulting bearing element includes areas of wear resistant materials and areas of anti-galling materials.

  • Patent number: 3981498
    Abstract: A roller having an outer textured cylindrical surface applies, by means of a constant current, a non-uniform charge pattern over the surface of a sheet of material such as, for example, sheets of paper or plastic as used in xerographic transparencies and/or over the surface of a conveying structure, such as a conveying belt, which moves the sheet material to, through, and/or beyond a xerographic transfer zone. The charge applied over the sheet material is of a polarity opposite to that of the charge applied to the conveying structure so that an electrostatic tacking force holds the sheet material on or adheres the sheet material to the conveying structure. Preferably the charge is applied over the surfaces of the sheet material and conveying structure which face each other.

  • Patent number: 3972524
    Abstract: A sheet intercept mechanism for temporarily retaining sheets released by the take-off grippers above a delivery pile at the output of a sheet fed printing press. The mechanism includes a horizontal support member and a clamping member normally in open position but having means for closing to capture the edge of a dropped sheet. A horizontal actuator coupled to the support member advances it to a sheet receiving position above the edge of the pile. Triggering means are provided coupled to the take-off grippers for closing the clamping member phased with the release of a sheet so that the clamping member clamps the dropped sheet preventing it, and any subsequently dropped sheet, from dropping upon the pile so as to permit the pile to be removed and a new pile board inserted. The triggering means is disabled as long as the horizontal support is in its retracted position and enabled only when the support is in sheet receiving position.

  • Patent number: 3968959
    Abstract: A document transport and separating device which utilizes opposing intermittent motion imparting devices having tips, the end of which are caused to move in an elliptical manner to feed, separate and align documents such as sheets of paper. One end of the tips of the devices are caused to move in an elliptical manner through a combination of application of an intermittent force parallel to the longitudinal axis of the tips of the device at its other end coupled with a rotational movement about a mounting spring which converts the longitudinal force into the elliptical motion. The longitudinal force is applied by pulsing a solenoid or electro magnet. The tips of the opposing devices are flattened at their point of intermediate contact to prevent multiple sheet feeding and greater surface contact and the coefficients of friction of the flattened tip surfaces are greater than the coefficients of friction between each of the sheets such that sheet feeding occurs.

  • Patent number: 3968960
    Abstract: Apparatus for inverting and stacking sheets successively conveyed along a path. Each sheet is sensed and actuates an inverting means which causes an element to engage and slow the leading edge of the sheet at a discharge region and deflect it from the path to a stacking platform. The trailing portion of the sheet continues to be moved by conveying means at approximately its original velocity and moves past the leading edge so that the sheet is rolled over and deposited in an inverted position on the stacking support or preceding sheet. The stacking support is sloped upward at its outer edge to facilitate removal of a portion of the stacked sheets while continuing the stacking operation. The conveying means extend over the stacking support to insure that the shorter sheets as well as the longer ones are properly deposited on the stack. By using a plurality of sheet engaging elements on the inverting means, sheets having a wide range of sizes can be deposited on the stack.

  • Patent number: 3966197
    Abstract: A printing machine receives single sheets which are removed from a stack by the suction cups of a feeding mechanism which is combined with a monitoring unit serving to detect the absence of sheets at the undersides of suction cups or the lifting of two or more sheets. The monitoring unit employs a transducer having two feelers which determine the thickness of lifted sheet material and an indicating device which is actuated by the feelers and produces signals serving to indicate the absence of sheets, the lifting of two or more sheets and/or to control the operation of the printing machine. The suction cups can form part of the transducer when the latter is designed to detect only the absence of sheets or they form part of a second transducer which is provided in addition to the first mentioned transducer.
