Abstract: ABSTRACT OF THE DISCLOSURE      A photoelectric detection system for a printer is described. The system is particularly useful for accurately detecting the position of type-bearing or printing elements of known width and spacing as they pass a predetermined location. An output signal is generated that substantially corresponds to the light and dark periods created as the elements pass between a light source and a detector. This output signal is integrated and compared with a reference signal that represents the ratio of the width of the elements to the spacing therebetween and the error is used to modify the light source and thereby adjust the output signal to correspond accurately with the dimensional criteria of the elements.

Abstract: Abstract of the Disclosure Dry polymerization of olefins is conducted in a smoother and more flexible manner in a series of reaction vessels in which the solid polymer being formed is maintained in the fluidized state by an upward stream of a gaseous mixture containing the olefin to be polymerized.  The polymer under formation circulates succesively from the first vessel to the last.  A transi-tion metal compound catalyst and an organometallic co-catalyst are introduced into the first vessel to initiate the reaction.  The stream of gas issuing from each vessel is recycled to the respective vessel and the amount of co-catalyst introduced into the first vessel is such that the atomic ratio of the metal of the co-catalyst to the transition metal of the catalyst is between 0.1 and 10,  In addition, a further organo-metallic co-catalyst is introduced into at least one vessel other than the first in a metal to catalyst metal atomic ratio between 0,1 and 20.  The polyolefin products are in powder form of relatively uniform size which leads to advantages during fabrication of articles therefrom.

Abstract: Abstract of the Disclosure Iron-containing materials are loaded into the top of a shaft furnace to form therein an upright column of the materials.  A burner forms a flame above the floor of the furnace to heat the base of the column and thereby melt the materials at the base of the column into a liquefied-iron melt on the floor of the furnace and a layer of slag on the melt.  In addition this flame formed by the burner forms a deposit in the furnace on which the column is supported.  Slag is continuously withdrawn from the furnace at a location substantially level with the deposit and the melt is withdrawn from the furnace at a location below the layer of slag and is heated as it is withdrawn.  This melt is withdrawn through an iron-drain conduit having an outlet end vertically positioned to be horizontally even with the lower surface of the slag and a refining vessel working inductively or by means of an electric arc may be provided in this outlet conduit for the continuous transformation of the liquefied iron into steel.

Abstract: ABSTRACT OF THE DISCLOSURE A protective mechanism is provided for valves having a nut through which a power-driven valve stem is threaded.  The mechanism functions to protect the valve seat against the continuation of thrust of the valve-stem closure element against the valve seat after the valve has been fully closed. The continuation of thrust force, unless prevented, occurs due to inertia of the drive motor after torque-sensing or other means have shut off the power to the motor.  The protective mechanism includes energy-absorbing means for absorbing the kinetic energy of the over-running drive motor and for stopping further rotation of the valve stem.

Abstract: ABSTRACT A hydraulic power supply unit has a fluid reservoir And a motor-driven pump which delivers fluid under pressure to a hydraulic system through a check valve in a fluid supply line.  A hydraulic pressure accumulator downstream of the check valve helps maintain the system under a predetermined pressure.  An accumulator pressure release valve automatically relieves the accumulator and thus the connected system of hydraulic pressure when the pump is inactive.  The valve has a valve body with a pilot port connected to the discharge side of the pump upstream of the check valve, an accumulator port in communication with the accumulator and a return port in communication with the reservoir.  Internal passages within the valve body interconnect the pilot, accumulator and return ports,  A movable valve member within the valve body moves to a closed position when the pump operates to block flow from the accumulator port to the return port, thereby pressurizing the accumulator and the system.  Opposed surfaces of the movable valve member in its closed position are subjected, respectively, to pump discharge pressure act-ing through the pilot port and accumulator pressure acting through the accumulator port.  These opposed surfaces are of unequal areas with the surface exposed to pilot pressure being of larger area so as to maintain the valve member in its closed position after the accumulator is fully charged. However, when the pump is deactivated so that no pressure acts through the pilot port, system pressure acting through the accumulator port moves the valve member to its open position to release accumulator and system pressure, reducing it to zero.

Abstract: ABSTRACT OF THE DISCLOSURE:        A railway house car side has an elongated opening closed by four doors disposed in  end-to-end relation lengthwise of the car with respect to each other, two of the doors, which may be designated end doors, being movable solely lengthwise of the car to uncover the end portions of the opening, the other two doors, which may be designated center doors, being movable transversely, to disalign them transversely of the car side from the end doors and lengthwise of the side alongside of the end doors to uncover the center portion of the opening.  The edges of the end doors nearest the respective ends of the car side have beveled flanges engageable with outwardly diverging door stops on the car side to wedge the end doors against the car side when closed and the opposite edges of the end doors have flanges overlaid by the adjacent center door edges to hold the end doors against the car side, and the edge of one center door overlies that of the other to afford a seal between them.  Each end door is provided with a manually actuable device for unwedg-ing the door and initiating its opening movement.  As a safety feature the side plate of the car mounts a common top retainer rail for both sets of doors comprising a generally S-section elongated member having an upwardly open inner channel forming the top retainer for the center door  cranks and a downwardly open outer channel forming the top retainer for the end doors.           The side plate also mounts an outwardly extending ledge over-lying the inner retainer channel to prevent the center door crank terminal from rising out of the inner retainer channel, and the web and outer depending flange of the outer retainer channel provide additional obstacles to outward movement of the center door top crank terminals in the event of failure of the common vertical web separating the two channels.  An idler safety retainer crank on each door is addition to the operating retainer cranks prevents separation of the door from the car side if the operating retainer cranks fail.  Novel gasket construction provides an improved seal between the adjacent doors and between the doors and the car side sill and side plate.
