| 141 | Position indicator | US3641966D | 1970-05-21 | US3641966A | 1972-02-15 | AUERDAHL OLAV |
| A position indicator system for remote indication of a position of a governing member. The indicator system has two bourdon tubes, the first of which is mechanically connected to the governing member and the second serves as an indicator actuator. The two bourdon tubes are interconnected with a capillary tubing in a closed hydraulic system and transmits the pressure variations generated by the mechanical subjection of the first bourdon tube by the governing member to the bourdon tube in the indicator. A compensating system has an additional pair of bourdon tubes, the first of which is installed at the location of the governing member, and the second of which is installed at the location of the indicator. The bourdon tubes are interconnected with a capillary tubing in a closed hydraulic system. A mechanical connection is provided between the pivotable fitting supporting the second bourdon tube and a free end of the bourdon tube at the indicator position.

| A plurality of manually operable master piston and cylinder assemblages and one or more slave piston and cylinder assemblages are connected in series with each other in a closed hydraulic circuit continuously pressurized at low pressure by way of an accumulator. Each master assemblage has a valving bypass circuit such that when the piston is manually driven it functions as a conventional piston. When it is driven by a differential in the fluid pressures applied to its opposite faces, it functions as a conventional piston until it closely approaches the ends of its strokes in opposite directions, respectively, whereupon the valving bypass circuit is rendered operative and bypasses the pressure fluid around the piston from one end of the cylinder to the opposite end. This renders the device self-synchronizing simply by manual movement of one of its master pistons through a complete forward and return stroke. Relief of excess pressures, and reduction of, and compensation for, thermal expansion and contraction are provided.

| 143 | Hydraulic uniflow control unit | US3576192D | 1969-11-10 | US3576192A | 1971-04-27 | WOOD RAY A R; ATKINS ROBERT A |
| There is disclosed a hydraulic control unit particularly for use in steering apparatus for boats, and in which the hydraulic fluid always flows in the same direction. The unit has pressure passages having ends to be connected to opposite sides of a pumping unit and opposite ends to be connected to the device to be controlled, such as the opposite ends of a slave cylinder which operates the rudder of a boat. A shuttle valve normally closes off the pressure passages and shuts them off from a common return passage which is connected to the reservoir of the pumping unit. When hydraulic fluid flows through one pressure passage, it shifts the shuttle valve to open the passage and connect the other passage to the return passage. The flowing fluid also passes through a check valve in the pressure passage and shifts a lock spool to open a corresponding check valve in the other pressure passage.
