Abstract: A valve actuator with an arcuate piston disposed within a housing including a side wall having a partition and two end plates whereby when joined, the housing forms a first and a second compartment. An arcuate piston travels between the compartments via an opening in the partition in an oscillating manner. A removable piston assembly enables removing the arcuate piston, output shaft and lever arms supporting the piston in order to remove the output shaft or to engage a spiral spring connecting the output shaft with the housing. The spiral spring may be pretensioned by winding before inserting the piston assembly into the housing. Fluid pressure applied to either compartment urges movement of the arcuate piston into the opposite compartment.

Abstract: A method and apparatus for determining the presence of a burned out lamp of a traffic signal is disclosed. The current applied to one or more banks of traffic signals and the voltage applied across such traffic signal banks are measured simultaneously. An electrical characteristic, such as impedance, of such traffic signal banks, is measured for each pattern of switch settings which control lamp illumination for signalling as they occur. Such characteristic is stored for each of the unique patterns which are repeated over and over again to control traffic. Such previously stored characteristic provides a baseline characteristic for each successive pattern of illumination of the lamps. With each pattern change, such characteristic is measured and compared with the previous baseline characteristic for the pattern to determine if a lamp has burned out.

An inner ring member attached through such hole and lies in one plane, and an outer ring member is linked to the inner ring member and through a grommet near an adjacent inner corner of the flag. The outer ring member lies in a plane that is substantially orthogonal to the inner ring as the flag flies in the wind.

Abstract: An improved detachable mooring system (1) is disclosed of the kind including a rotatable turret (10) mounted on the vessel (5) and a buoyant spider buoy (20), secured by chains (22) to the sea floor, which may be selectively connected by means of a hydraulic connector (209) to the bottom of the turret (10). One improvement relates to providing a roller bearing (598) between an upper part of the turret and an interior ring (56) of a well (50) of the vessel (50) at a level higher than sea water can reach under fully loaded conditions of the vessel. Such improvement provides an elastomeric pad (584) between the bearing (598) and a support ring (56) to reduce moment loads and to compensate for manufacturing tolerances of interface surfaces of the bearing (580, 586) and the support ring (56). Alternatively one or more spring stacks (791, 793) may be used rather than an elastomeric pad.
