Abstract: A linear motion device of the type in which magnetic coils surround a shaft lifting and lowering slugs which contain gripper elements which in turn may be selectively engaged and disengaged from the shaft. An upper coil operates to lift an upper slug while an upper central coil operates to effect engagement between the shaft and the upper slug. A lower coil operates to pull down a lower slug while a lower central coil operates to effect engagement between the lower slug and the shaft. The single central coil operates to simultaneously pull down the upper slug and lift the lower slug whereby two lifting steps are accomplished in each cycle of the lifting device.

Abstract: A fuel burner safety control circuit for burner safety shutoff valves functioning in different operational modes depending upon the occurrence of an interruption in power to the circuit or an unsafe operating condition in the overall system so as to be capable of distinguishing between a momentary power interruption where the burner should not be shut down and an emergency condition where the burner should be shut down substantially immediately. The safety control circuit has a deenergize-to-trip burner safety shutoff valve with an integral time delay to maintain burner safety shutoff valve energization during momentary power interruption, and a bypass arrangement permitting the time delay to be bypassed during emergency trip conditions to provide substantially immediate burner safety shutoff valve deenergization for closing down the burner system. This capability of distinguishing between momentary power interruptions and emergency trip conditions is accomplished by using a circuit having parallel time delay relays to activate switches set in series in a time delay circuit. The time delay relays function in opposite energization senses (i.e., energize to trip and deenergize to trip) in activating the switch with which it is associated, one switch being normally closed and the other closed on application of power to the safety control circuit. On a power interruption, both relays would assume a deenergized state maintaining the switches closed for a set period of time to continue the integrity of the time delay circuit to prevent trip of the deenergize-to-trip burner safety shutoff valve. This is accomplished by the deenergize-to-trip relay holding in the powered closed switch for a discrete period of time and the energize-to-trip relay (being deenergized) having no effect on the normally closed switch. In an emergency unsafe operating condition the deenergize-to-trip relay would again be deenergized to maintain the powered closed switch closed, but the energize-to-trip relay would assume an energized state substantially immediately opening the normally closed switch to trip the deenergize-to-trip burner safety shut off valve for closing down the burner system.

Abstract: A SWITCH FOR DIRECTING A STREAM OF FLUIDIZED PARTICULATE MATERIAL FROM A PIPELINE CONVEYOR PIPE EITHER THROUGH A BYPASS CONDUIT TO A CONTINUATION OF THE PIPE OR THROUGH AN ENLARGED CONDUIT TO A RECEPTACLE OR HOPPER. THE CONDUITS FORM A UNIT PIVOTED TO SWING TRANSVERSELY OF THE CONVEYOR PIPE AND SELECTIVELY ALIGN AND CONNECT EITHER THE BYPASS CONDUIT INLET OR THE ENLARGED CONDUIT INLET WITH THE CONVEYOR PIPE. THE ENLARGED CONDUIT FORMS AN EXPANSION CHAMBER HAVING STREAM TURNING BAFFLES DIRECTING THE STREAM THROUGH THE CHAMBER TO AN OUTLET IN THE BOTTOM.

THE OUTLET CARRIES AN O RING SEAL MEMBER WHICH IS FORCED INTO SEALING RELATION AROUND A DISCHARGE PASSAGEWAY IN A PLATE, FORMING THE UPPER PORTION OF A HOPPER, BY THE SWINGING MOVEMENT OF THE SWITCH AND SEALS THE JOINT BETWEEN THE CHAMBER OUTLET AND THE PLATE. THE PIVOT IS POSITIONED AT ONE SIDE OF THE SWITCH MEMBER CENTER OF GRAVITY SO THAT THE WEIGHT OF THE SWITCH MEMBER WILL ASSIST IN THE SEALING. THE SEAL MECHANISM FOR THE BYPASS OUTLET IS USED TO RESIST THE END THRUST ON THE SWITCH.

Abstract: A VESSEL RECEIVES A FLUID MIXTURE TO PROCESS THE MIXTURE. REMOVAL OF THE PROCESSED FLUIDS IS CARRIED OUT WITH A PRESSURE REDUCTION. A VAPOR IS EVOLVED FROM THE MIXTURE AND COMPRESSES AND MIXED WITH THE FLUID MIXTURE RECEIVED BY THE VESSEL TO RAISE THE ENTHALPY OF THE MIXTURE TO CARRY OUT THE PROCESS IN THE VESSEL.

Abstract: A system for detecting a fault in the output signal of a flame scanner circuit, the system comprising ball means, normally gravity biased to a nonblocking position, periodically pneumatically activated to intercept, and block, the scanning view of a glow discharge tube detector used to indicate the presence of a flame. A logic circuit having an AND gate receives independent signals from the pneumatic activating means for the ball means (indicating ball means actuation) and from the flame scanner circuit (indicating positive firing of the glow discharge tube detector). The tube detector, of course, should not be firing, and thus signaling the existence of a flame, when its scanning view is blocked by the ball means. If both of the abovementioned signals reach the AND gate at the same instant, the gate will operate to pass a signal to a fault indicator which may operate any suitable alarm means to indicate a fault in the glow discharge tube detector.

Abstract: Apparatus for providing an indication of the position of a movable member comprising a magnet which moves with the member and a plurality of magnetic flux responsive switches individually positioned along a line parallel to the path of movement of the member. A voltage divider electrically connected to the switches provides a signal commensurate with the position of the member to a position indicating device which includes a second voltage divider, a stepping relay and means to indicate the position of the stepping relay.

Abstract: A structure for mounting equipment at a subsea location has a platform member and an anchor member, each with independently adjustable buoyancies. The two members are interconnectable and can be nested together for towing to their emplacement site, at which their buoyancies are sequentially adjusted, the anchor positioned, and the platform winched down and secured to the anchor. The platform is retrievable to the surface without an external power assist. The anchor member may also be retrieved if external power is available to blow the anchor ballast.
