Abstract: A sequential stepped directional control valve accepts pressurized hydraulic fluid from a pressure port, and directs that pressurized fluid to a first stage port, or to both a first stage port and a second stage port. In the neutral position, the valve blocks the flow of pressurized hydraulic fluid into the valve. In the first stage position, pressurized hydraulic fluid flows into the valve and is directed by the valve to the first stage port, however, the fluid flow to the second stage port is blocked. In the second stage position, pressurized hydraulic fluid flows into the valve and is directed to both the first and second stage ports. When the valve transitions from the first stage position to the second stage position, the valve does not cycle through a neutral position, and the flow of pressurized hydraulic fluid to the first stage port is uninterrupted.

Abstract: A hoisting and lowering driving engagement multi-row chain is disclosed, in which bending of the connecting pins in the chain is suppressed to avoid fatigue failure. Additionally, the load carrying balance in the chain width direction is improved, and contact vibrations and contact noises generated between the chain and the hoisting and lowering sprockets are suppressed. Endurance of the bush in the chain is thereby improved. Bending of connecting pins is avoided by press-fitting bushes, through which connecting pins pass, into intermediate tooth plates. This also improves load carrying balance widthwise. Contact noises and vibrations between the bushes and sprockets are suppressed by providing bushes with a separate sprocket engagement portion having a larger diameter than the press-fitting portion of the bushes.

Abstract: An engagement chain type hoisting and lowering device is disclosed, having a hoisting and lowering table attached to the upper end of two or more pairs of hoisting and lowering driving engagement chains. A driving motor drives two pairs of hoisting and lowering sprockets which, in turn, raise or lower two pairs of hoisting and lowering driving engagement chains. By arranging two pairs of hoisting and lowering driving engagement chains on two opposed sides of the hoisting and lowering table, buckling of the hoisting and lowering driving engagement chains is suppressed, resulting in stable hoisting and lowering operations without slippage of articles on the hoisting and lowering table, and chain endurance is improved. The device is designed so that the lowest position of the hoisting and lowering table can be lower than the height of the peripherally located driving motor, for ease and safety of operation and maintenance.

Abstract: A wire rope has an independent wire rope core including lubricated individual core wires that are encapsulated in a tubular sheath of elastomeric or polymeric material surrounding the core wires and retaining the lubricant. A plurality of strands are located radially outwardly from and adjacent to the core. Each of the strands include strand wires that are lubricated. The strand wires are encapsulated in a tubular sheath of elastomeric or polymeric material that retain the lubrication for the strand wires. The core and strand encapsulating materials prevent direct metal-to-metal contact between core wires and strand wires, and between strand wires of adjacent strands. The core and strand encapsulating materials are applied in a manner so as to avoid loss of lubricant. Retaining lubrication and preventing direct metal-to-metal contact significantly improves the useful life of the wire rope.

Abstract: An offset lithographic printing press combined with a gapped or seamed cylindrical offset printing blanket having pre-made blanket material mounted on a cylindrical sleeve is disclosed, wherein conventional, manufactured blanket material in flat form is adhered to a cylindrical sleeve to economically produce a cylindrical sleeved blanket. The leading and trailing ends of the flat blanket material are joined in close proximity such that a small gap is formed. A seam may be made with a filler material that fills the remaining gap resulting in a seamed sleeved blanket. In use, the blanket's printing surface, which excludes the gap or seam, is aligned with the printing plate's image-bearing surface. Consequently, no loss of print length results from the gap or seam.

Being narrower than the plate cylinder gap, no loss of print length results from the seam.

Abstract: This invention generally concerns electronically controlled hydraulic valves for use in electro-hydraulically controlled transmissions. The proportional pressure control valve 20 includes a hollow cage 42 pierced by cage tank ports 52, cage clutch ports 54, and cage pump ports 56. The cage pump ports 56 receive fluid from a pump. The cage clutch ports 54 supply fluid to a hydraulic actuator. The cage tank ports 52 return fluid from the valve 20 to a tank from where fluid circulates back to the pump. Main spool 112 controls fluid flow between cage clutch ports 54 and cage pump ports 56 or cage tank ports 52. An electro-magnetically operated pilot valve regulates fluid pressure applied to a control pressure surface 138. A feedback pressure passage 126, having feedback restriction orifice 128, restrains the rate fluid flows between the cage clutch ports 54 and the feedback pressure surface 114.
