Abstract: ABSTRACT OF THE DISCLOSURE         This disclosure deals with a fuel injector for an internal combustion engine.  The injector includes an injec-tor body having a fuel metering chamber formed therein which receives fuel from a fuel supply.  A plunger is movable into the chamber in an injection stroke to force fuel from the chamber and out of the injector through spray holes.  A valve member is mounted in the path of fuel flow from the chamber to the spray holes, the valve member being movable between first and second positions.  In the first position, the valve member seals the path and prevents air in the combustion chamber from mixing with the fuel being metered into the metering chamber, and in the second position the valve member closes the spray holes to terminate injection.  During an injection stroke, the plunger moves the valve member from the first position toward the second position, and fuel in-jection takes place while the valve member is intermediate the first and second positions   The valve member is also subjected to hydraulic forces at the end of the injection stroke, which move the valve member into the second position in order to abruptly terminate injection.

Abstract: ABSTRACT OF THE DISCLOSURE           The disclosure describes a swing valve having a valve plate and a drive for producing the swinging movement of the valve plate.  This valve should be capable of producing a sealing force when the valve plate is in closed position.  For this purpose, the drive which produces the swinging movement of the valve plate also serves to produce a movement of the valve plate at right angle to the sealing plane, after the valve plate has come to a stop in the closed position.

Abstract: ABSTRACT     An ice preventing/removing device is mounted in the air intake duct of a gas turbine engine.  The device comprises two or more rows of vertically extending, hollow tubular mem-bers connected between upper and lower headers, through which exhaust gases are drawn.  The tubular members are specially designed to both remove moisture droplets from the incoming air and heat the air.  Both condensate and precipitate icing in the inlet system can thereby be prevented and existing ice accumulations can be eliminated without necessarily heating the inlet air to 32°F. or higher.  Economy of turbine opera-tion and increased turbine output capacity can therefore be gained.

Abstract: ABSTRACT OF THE DISCLOSURE      A system for creating an alarm whenever the pressure inside of a combustion furnace is higher than atmospheric pressure.  The system uses a pressure reference comprising a chamber which is designed to average out momentary wind-induced fluctuations of pressure in the atmosphere and to provide a substantial volume of air inside the chamber which is maintained at an average value of atmospheric pressure.  A conduit is passed through the wall of the furnace to the point under the furnace arch where the pressure is to be measured.          This conduit is connected by a tubing to the chamber.  A temperature sensing means is inserted in the conduit as to measure the temperature of gas flowing through the tubing from, or to, the furnace.  Normally, because of the draft in the furnace, air will flow from the chamber to the furnace.  Whenever the pressure in the furnace is greater than atmospheric, hot furnace gases will flow in the reverse direction and the temperature sensor will indicate this flow and cause an appropriate alarm or alarms.

Abstract: Abstract of the Disclosure A device is described for aligning coiled sheet material in the die of a power press during stamping operations.          It includes a coiled sheet material feeder having a pair of powered gripping rollers for gripping and advancing the sheet material, these rollers being mounted on a head portion which is supported on a base with the feeder head being arranged to pivot on the base about a vertical axis and to move on the base laterally to the direction of travel of the sheet material while being fixed against movement parallel to the direction of travel of the sheet material. Hydraulic cylinders are provided for separately laterally moving forward and rearward portions of the feeder head and these are operatively connected to detector means, such as feeler actuated solenoid valves posi-tioned along one side of the travel path of the sheet material between the feeder head and power press.  These detector means sense the edge of the sheet material passing through the power press and cause the feeder head to laterally adjust and/or pivot to maintain the sheet material in proper alignment within the press.

Abstract: FLUID  TRANSMISSION  CIRCUIT          ABSTRACT  OF  THE  DISCLOSURE    A fluid transmission circuit in which three or more pumps, adapted to be driven in unison by a prime mover operating at constant power output, draw fluid from a reservoir and deliver it to a reversible fluid motor via a control valve incorporating forward, neutral and reverse positions, the motor being driven, when the circuit is in use, against a fluctuating resistive force. The fluid outputs of two or more of said pumps are con-trolled by the output of a diverting valve whose input is connected by a separate pressure-sensing line to the fluid flow passing through the motor and which is initially biassed into a position in which each of said fluid outputs from said pumps is delivered to the motors The arrangement is such that, as the demands on the motor increase and the pressure of fluid passing through the motor rises through a succession of predetermined levels, the pressure-sensing line will sense the rises in pressure and, at each successive pressure level, will cause the diverting valve automatically to divert the fluid outputs of successive ones of said pumps back to the reservoir without passing through the motor, the pump outputs being automatically switched into the motor supply line again, one after the other and in the reverse order from that in which they were switched out, by the diverting valve as the demand on the motor subsequently falls.

Abstract: Case 2558 ABSTRACT OF THE DISCLOSURE         Apparatus for determining and controlling wheel slip in a locomotive driven by d.c. motors has sensors which sense the wheel speeds of the different wheels and provide signals representing the different wheel speeds to a comparator.  The comparator provides a signal  representing the difference between the highest and lowest wheel speeds.  A converter also acts on the signals representing the different wheel speeds to provide signals representing the acceleration of the different wheels and a selector selects the signal representing the largest acceleration.  The signal representing the difference between the highest and lowest wheel speeds, and the signal representing the largest rate of acceleration are added together to provide a fault signal.  A signal modifier modifies the fault signal to provide a controlled decay rate and the resulting signal is used to control the d.c. motors.

Abstract: A DIVIDED HOUSING UNIPOLAR DYNAMOELECTRIC MACHINE               ABSTRACT OF THE DISCLOSURE         A unipolar dynamoelectric machine has a divided housing and uses a liquid metal to effect variable resistance control of the machine current.  The machine includes a stator comprising a housing having first and second portions and a field coil.  The housing portions are electrically insulated from one another and together define a chamber having an axis that is coincident with the axis of the annular field coil.  A rotor is journalled in the housing and a control member extends into a recess in the rotor.          The rotor rotates about the control member and is spaced from the stator and from the control member.  The spacing produces annular spaces into which a liquid metal may be forced by an expandable bellows arrangement.  Current flow in the machine is through the control member, the space between the control member and the rotor, the rotor, the space between the rotor and the stator, and the stator.          The amount of liquid metal in the annular spaces between the control member and rotor and between the rotor and stator determines the amount of current flow and the machine output characteristics.
