  • Patent number: 5820676
    Abstract: An apparatus for applying precise, uniform, coatings to elongated shafts, such as golf club shafts. Shafts are held by a gripper in a downwardly hanging array. A paint head assembly is moved upwardly over each shaft in sequence to apply a paint coating to a selected portion of the shaft length. The paint head assembly includes a flexible container including a central hole, a vertically moveable edge frame and an expander for changing the area of the hole. Raising the frame forms the container into a bowl like configuration, so that paint will contact a shaft extending through, and in contact with, the hole. The assembly is moved up along the shaft to apply a layer of paint, with the hole area varied to accommodate shaft taper, steps, etc. When the desired shaft length has been painted, the frame is lowered, changing the container to a trough-like configuration with pint away from the hole region. The expander widens the hole out of contact with the shaft and the assembly is lowered to below the shaft end.

  • Patent number: 5817161
    Abstract: In forming a piano-convex lens from a column-like lens blank by heating the blank to a temperature higher than the transition temperature thereof and by pressurizing an upper die with a closed space formed between the blank and the upper die, there are alternately repeated operations of pressurizing the upper die and stopping the application of pressure thereto. Through the control of the amount of displacement of the upper die, the maximum pressure of gas in the closed space at each pressurizing step is so controlled: as to be low according to the surface viscosity of the blank to the extent that no local concave deformation in the surface of the blank is produced; and as to be high to the extent that gas caught in the closed space is discharged at each step of stopping the application of pressure.

  • Patent number: 5795438
    Abstract: A number of distinct parallel digesters are fed with chips from a common steaming vessel. After steaming the chips are slurried and pressurized, and substantially simultaneously the steamed, slurried, and pressurized chips are transferred to at least some of (and typically each of) the distinct parallel digesters. A material stream is split into a number of individually controllable material streams (one for each of the digesters) either at the discharge from the steaming vessel, after slurrying (or at the discharge from a slurrying vessel), or after pressurizing (e.g. in a high pressure transfer device). For example a multi-branch conduit may be connected to the slurry outlet from the high pressure transfer device, the conduit having a branch directly connected to each of the digesters. A distinct return conduit may also be provided from each of the digesters to the high pressure transfer device, each return conduit preferably has a distinct flow control device and/or pump which are individually controlled.

  • Patent number: 5795390
    Abstract: A liquid dispensing system has a number of cartridges, preferably two or four, selectively coupled to a single motor with a respective clutch for dispensing dots of liquid at high speed. The motor drives a spur gear that meshes with individual spur gears associated with each of the clutches. Multiple cartridges are thus activated with a single motor and are housed together in one housing. Each cartridge is movable relative to the housing and is biased downward to a dispensing position with a spring. Air is selectively provided between the dispensers and the housing to drive the cartridges upward to a non-dispensing position. When the air is not provided, the spring returns the cartridge to its downward position. By moving the cartridge relative to the housing, the assembly can dispense at different locations without it being necessary to move the entire pump assembly every time a dot is dispensed.
