  • Patent number: 6000687
    Abstract: A hydrostatic holding device has a first actuator constructed to increase the pressure of a hydraulic fluid within a pressure chamber to urge a metal sleeve into firm engagement with a workpiece received in a hydrostatic sleeve and a second actuator constructed to relieve the high pressure within the system to permit the workpiece to be removed from the sleeve when desired. Preferably, the first and second actuators are separate cylinders each having pistons displaceable by separate actuating rods to conveniently achieve the increased pressure needed to firmly hold the workpiece and the bleeding or relieving of the pressure so that the workpiece can be removed from a holder. A check valve downstream of the first actuator prevents reverse flow of the hydraulic fluid from downstream of the check valve back into the first actuator and thereby permits the increased pressure to be maintained independently of the first actuator.

  • Patent number: 5820897
    Abstract: This invention discloses a method of holding and transporting a hollow flexible belt throughout a coating process. The method includes placing an expandable insert into the hollow portion of a seamless flexible belt, and expanding the insert until it forms a chucking device with a protrusion on at least one end. A mechanical handling device is then attached to the protrusion, and will be used to move the chuck and the belt through the dipping process, as materials needed to produce a photosensitive device are deposited onto the surface of the belt, allowing it to be transformed into an organic photoreceptor. The chucking device and flexible belt are then removed from the mechanical handling device, the belt is cut to the desired width, and the chuck is removed from the inside of the photoreceptor.

  • Patent number: 5707052
    Abstract: system of helically coiled air hoses (18) supports a printed circuit board (14) in an assembly station, and allows the conveyor rails (15, 16) to adjust in and out, accommodating various widths of printed circuit boards (PCB). One of the conveyor rails is fixed and the other is movable. Air hoses are each formed in a helix and placed below the PCB and above the upper work surface of the assembly station, and arranged so that when the air hoses are pressurized the helix expands in diameter to become wedged between the work surface and the PCB to support it from below. One end of each of the air hoses is connected to the fixed rail and the other end is connected to the movable rail. The hoses are sufficiently flexible so as to be free to move about in a lateral direction, but they are diametrically rigid to prevent the diameter of each hose from changing substantially when the hoses are pressurized.

  • Patent number: 5695393
    Abstract: A tool for the precision processing of the optical surfaces of lenses has an elastic membrane (10), connected to a rigid holder (20), which incorporates a processing segment (11) and a bellows-type segment (12). Together, the membrane (10) and the holder (20) delimit a cavity (15), which is filled with a material (16) that becomes ductile under specific conditions, and which can be induced, at will, to form a flexible or rigid supporting layer for the membrane (10). When the material (16) is in its ductile state and the processing segment (11) contacts the optical surface, the bellows-type segment (12) exerts forces on the ductile material (16) which cause it to press the processing segment (11) against the optical surface, so that the tool retains its shape after the ductile material (16) has become rigid. As this tool can be used to shape any type of optical surface, it is particularly well-suited for the processing of prescription lens eyewear.
