The hydraulic portion of the system includes two pair of combined electrical and hydraulically operated pilot trip valves that are so arranged that the opening of any one valve of each pair decreases the hydraulic trip pressure to close rapidly the steam inlet valves to the turbine; that an open or closed failure of a single trip valve does not prevent a valid trip or cause an unwarranted trip; and finally that an open failure of one pair of the valves does not result in an unwarranted trip. Each pair of valves is electrically operated from an independent voltage source such that the electrical failure of one source does not cause or prevent an unwarranted turbine trip.

Abstract: This specification discloses a method of providing an ice structure at a desired offshore, frigid location. The structure is constructed at a first offshore location by accumulating ice on a base of naturally occurring ice.

Abstract: The specification discloses a method and system for detecting brake wear in a metal forming machine having a ram operable by a rotative drive and further having a brake for stopping the ram. The amount of rotation of the drive for the machine is determined from the time of energization of the brake to the time of stopping of the ram by the brake.

An alarm is generated as the determined amount of rotation of the drive exceeds the predetermined magnitude, thereby indicating excessive brake wear. Further operation of the ram is then prevented upon the generation of an alarm. The specification further discloses a check system for checking the operation of various components of the detection system prior to detecting of the brake wear.

Abstract: A flow transmitter for monitoring pulsating liquid flow rates, such as intermittent or cyclic impulsion produced by reciprocating pumps, employs a short stroke, variable area flowmeter having an armature core mounted in the flowmeter stem. As the stem rises and falls with flow, the armature moves within a linear variable differential transformer coil to produce an A. C. voltage following core deflection. This A. C. deflection signal is converted to a milliampere D. C. signal by means of a demodulator which through a long-time constant RC filter network averages the pulsed flow variations to provide a continuous non-inferential measurement proportional to flow.
