Abstract: VAVLE AND SEAL ASSEMBLY THEREFOR                      Abstract of the Disclosure An internal safety shutoff and operating valve includes a housing defining a valve seat and a cylinder.  A piston slidable in the cylinder includes a valve closure member engageable with the seat for closing the valve.  A spring biases the piston toward the closed position, and an actuating assembly moves the piston against the spring to the open position.  One set of main ports communicates with the valve seat between the valve seat and the cylinder, and the other set of main ports communicates with the opposite side of the valve seat.  Pressure forces on the piston are balanced by a passage in the piston intercommunicating the cylinder with one set of main ports.  In order to prevent leakage between the piston and the cylinder wall to the other set of ports, a seal assembly including a groove in the piston wall and a seal ring in the groove is provided.  The groove includes rounded inner corners, and the seal ring is provided with inner and outer grooves interconnected by passageways.  When the seal assembly is subjected to a pressure differential, the grooves and passageways equalize the pressures on both sides of the seal, and the seal is moved axially in the direction of the pressure drop against a rounded corner.  The rounded corner cams the seal radially against the cylinder wall to provide positive sealing with the wall of the groove and with the wall of the cylinder.

Abstract: MEANS FOR DETECTING GROUND INSULATION FAILURE FOR ROTARY ELECTRIC MACHINES     ABSTRACT OF THE DISCLOSURE         Electrical potentials are induced in the rotating shaft of many rotary electrical machines because of stray flux that exists in the machines.  Unless provided with adequate ground insulation to interrupt the circuit, currents can flow through the machine bearings and other parts to ground and thereby expose the machine to severe damage.  The device of this invention measures the voltage across the shaft and the bearing to indicate if there is a circuit for excessive current leakage from the bearing to ground.

Abstract: ABSTRACT OF THE DISCLOSURE A method of removing nitrogen oxides from a gas stream, for example the waste gases of a plant in which nitrogen oxides is processed, includes reducing the nitrogen oxides by means of ammonia in the presence of a catal-yst.  During the reduction step, the waste gas is under superatmospheric pressure of up to 12 atm. abs.  Preferably the pressure is between 2 and 5 atm. abs.  The temperature of the waste gas is raised to between 260°C and 340°C prior to reduction.  The ammonia can be introduced in the form of ammoniacal waste gases derived from the synthesis of ammonia.  The apparatus for perform-ing this method includes a reactor having one or more catalyst beds.  A heat exchanger is interposed between the exit of the reactor and a gas turbine. The exchanger heats the waste gas entering the reactor by utilising the heat contained in the waste gas leaving the reactor.  The gas turbine expands the waste gas from the reactor prior to its discharge through a stack.

Abstract: ABSTRACT       A turbocharger system.  One impeller of the turbocharger is driven by exhaust gas from an internal combustion engine, the other impeller functions as a pump to either compress air or to pump air in order to convey granular material.  The impeller wheels are spac-ed and are mounted at the ends of a common shaft.  The shaft is continuously lubricated, the spent lubricant being fed to an oil sump (crankcase).  The specific improvement is a pressure bleed passageway between the chamber which receives engine exhaust pressure and the oil exhaust line.  The bleed allows a portion of engine exhaust to pass to the sump exhaust line and assist oil flow to the sump by virtue of a pressure differential.  This action, in turn, inhibits spent oil from passing through the seals and passing into either or both impellers when oil sump (crankcase) pressure is higher than atmospheric or where there are unfavor-able to gravity flow conditions existing in the oil return line.  Another portion of the system bleeds air from a high pressure reservoir to the interior of the oil sump line to assist spent oil flow to the sump.

Abstract: FOLDING HANDLE AND   CLUTCH CONTROL            Abstract of the Disclosure A folding tiller handle is made in two pieces connected for limited relative longitudinal and pivotal movement, one piece being a permanent part of the basic tiller assembly.  A belt tightening idler sheave is associated with a belt drive which provides the motive force for  rotating the tiller tine assembly.  A control, which includes two separable rigid rod members, moves the idler sheave into and out of tightening engagement with the drive belt.  The rods are joined through a connection which imparts rotary motion from one rod to the other and which also permits relative longitudinal movement therebetween to separate the rods.  The rods are associated with respective pieces of the tiller handle so that when the handle is separated or folded, the control connection to the tightening sheave through the rods is interrupted and the drive belt cannot be tightened to establish the tiller drive.

Abstract: ACTUATING MECHANISM FOR ELECTRICAL SWITCHES       Abstract of the Disclosure An actuating mechanism for actuating electrical switches to insure coordinated connection of circuits vital to safe operation of a mass-transit vehicle includes a frame upon which are mounted one or more electrical switches.  Also included is a cam rotatably mounted on the frame for actuating engagement with the switches upon rotation of the cam by key or similar device.  The actuating mechanism further includes a toggle mechan-ism that is connected at one end to the frame and at the other end to the cam at a point spaced from the point of mounting of the cam to the frame. Secured to the toggle mechanism is a spring whose dead center position does not coincide with the point of actuating contact of the cam with the switch such that upon rotation of the cam, the spring resists movement of the cam until the dead center position of the spring is reached.  As the cam is rotated beyond the dead center position of the spring, the spring assists in the rotation of the cam through the point of actuating contact with the electrical switches.  The actuating mechanism further includes a lock arrange-ment for locking the cam against rotational movement.
