  • Patent number: 5893334
    Abstract: A system for mooring a floating storage vessel (10) in the open sea for remaining on station at all times without any disconnection of the vessel (10) from the mooring system. The mooring system includes a plurality of anchor legs (26) connected to a turret (20) in the well (18) of the vessel (10) with at least one submerged support buoy (28) for each anchor leg (26). The submerged support buoy (28), by supporting a substantial portion of the weight of the associated anchor leg (26), reduces the vertical loads on the turret bearings (46, 48) and permits the turret (20) to be easily rotated from the torque exerted by the anchor legs (26) without any separate turret drive means. The system includes in FIG. 5 an embodiment in which a plurality of support buoys (28A) are provided for each anchor leg (26A). The system includes in FIG. 6 an embodiment in which the floating storage vessel (10B) is permanently moored to a mooring buoy (25B) secured by a plurality by anchor legs (26B) to the sea bed (16B).

  • Patent number: 5893389
    Abstract: A poppet check valve (20) in the embodiment of FIG. 1 has a valve body (30) with a fixed unyielding metal seat (38) for engaging in metal-to-metal sealing contact with a sealing surface (48) on poppet valve member (34) at relatively high fluid pressure ranges. The metal seats 38 and 48 may both be frusto-conical in shape or one frusto-conical and the other spherical. A compliant metal sealing member (42) engages sealing surface (48) in metal-to-metal sealing relation at low fluid pressures prior to engagement of sealing surface (48) with fixed metal seat (38) at high fluid pressures. Alternative embodiments are shown in FIGS. 3-7. The embodiment of FIG. 7 shows a poppet check valve with a pair of staged flexible metal sealing members (42D, 43D) which are integral with body (30D) for progressively engaging the sealing surface (48D) of poppet valve member (34D) prior to engagement of fixed metal seat (38D).

  • Patent number: 5872478
    Abstract: An SCR firing circuit is provided which includes a plurality of opto-couplers, diodes, a capacitor and an SCR, utilized to control the AC power applied to a load, such as a vibratory feeder. In various embodiments of the invention, one or more opto-couplers act as solid state switches and also isolate a control signal from the AC line voltage. The capacitor is charged from an AC power source through the diode during a half cycle of the AC line voltage, and remains charged until the SCR is triggered. In response to a control signal rendering the opto-couplers conductive, the capacitor is discharged through the opto-couplers to fire the SCR and provide AC power to the load. A back-to-back SCR firing circuit is also provided which fires a first SCR when a line voltage is positive and which fires a second SCR when the line voltage is negative, which may be utilized to adjust the frequency of the application of power to the load independently of the frequency of the AC power supply.

  • Patent number: 5868241
    Abstract: A base-excited vibratory conveyor includes an elongated conveyor trough, and an elongated support structure extending generally beneath the conveyor trough. A plurality of springs operatively interconnect the trough with the support structure, whereby vibratory drive of the support structure effects vibratory motion of the trough for conveyance of materials therealong. The support structure includes a plurality of cross-member assemblies which facilitate operative connection of the springs to the support structure, while enhancing the structural integrity of the support structure. The overall conveyor construction can be relatively lightweight in configuration, thus facilitating economical manufacture and operating efficiency.

  • Patent number: 5860840
    Abstract: A disconnectable vessel mooring system including a storage vessel (10) with a turret (32) mounted therein so that the vessel is free to weathervane about an anchored turret. A spider buoy (44) in a docked position is received within the turret (32) with the upper part of the buoy at a position above the sea water level to permit dry servicing of the buoy (44). Anchor legs (68) in the docked position are secured to the turret (32) by securing means (71). Guide tubes (72) on the outer surface of the buoy (44) receive the anchor legs (68) therein for limited longitudinal travel. Selected anchor legs (68) may be disconnected from the buoy (44) when detached from the turret (32) for lowering onto the sea floor to reduce the weight of anchor legs supported by the buoy (44).
