Abstract: ABSTRACT   An apparatus for cleaning the top or bottom horizontal section of a coke oven door seal ring and which applies approximately constant pressure to all points along its lateral path.  A cleaning head is pivotally mounted on the terminal end of an arm member which is, itself, pivotally mounted to oscillate in a horizontal arc on a base structure.  An extension of the door cleaner frame is suspended above the arm and on this frame there is mounted a spring.  A vertical, spring driven link is attached at its upper terminal end to this spring and at its lower end to the base.  This link is also medially attached to the frame so as to pivot in a vertical arc about this point of attachment.  A second idler link which is pivotally connected at its top to the frame and at its bottom to the pivoting base keeps the cleaning head from being vertically displaced out of contact with the seal ring,

Abstract: ABSTRACT OF-THE DISCLOSURE     A gas-dynamic pressure wave machine with an exhaust gas bypass which includes a flap provided in the bypass which opens with higher engine speeds in order to limit the peak pressure in the internal combustion engine.  A flap control is provided via a pressure box with a process pressure, For example, exhaust gas pressure, as the controlling dimension.          The process pressure is coupled with a constant pressure such as a vacuum or excess pressure for altitude compensa-tion and temperature compensation in such a manner that the process pressure is to be raised by the same amount with a decreasing  atmospheric  pressure.   For this  purpose,  the pressure  box  is  divided  into  first  and  second separate chambers by means of a diaphragm and the process pressure acts on the first chamber while the second chamber is main-tained under a constant pressure.  The diaphragm acts on the flap through a plurality of rods.

Abstract: ABSTRACT         A focussing apparatus essentially comprises a truncated outer cone and a coaxial inner cone which between them define a narrow annular passageway through which signals can be transmitted from and to a transducer.          The arrangement tends to create a substantially parallel beam of radiation and the focussing apparatus has very good directional characteristics.  The transducer is mounted on a pillar within a transducer housing collar resulting in a very compact design.  The inner cone is held in place by a number of radiating ribs so that the apex of the cone lies on the plane of truncation of the truncated cone.

Abstract: DISTRIBUTED TIME DIVISION MULTIPLEXING BUS            Abstract High density time division busses suffer from many problems, one of which is that impedance discontinuities cause signal reflections to occur along the bus.  These reflections, in turn, affect the settling time and noise margins of the bus and thus reduce the time "window" in which valid signals may be received.  There is disclosed a transmission bus structure which allows for bidirectional, multi-port operation by using current drivers instead of the traditional voltage drivers for placing data signals on the bus.  The transmission bus is designed in a manner which allows transmission and reception from a single clock on the same clock edge, thereby substantially increasing the time allowed for transmission response and also simplifying the clock distribution requirements.

Abstract: FREIGHT CAR CONSTRUCTION                    ABSTRACT    A freight car is constructed with an undercarriage having a flat cargo floor and with an upright fixed end wall at each end of the floor.  A gantry in the form of an arch extends upwardly from the floor substantially centrally between the end walls and a hood support rail extends between the fixed end walls on each side of the floor.  The space above the floor is covered by a hood which is of a length to extend between the gantry and one end wall and which includes a roof portion which overlies the gantry and the one end wall and side wall portions which extend downwardly from each side of the roof.  The side wall portions carry rollers or casters which are engageable with the rail for supporting the hood for movement along the rail.   The hood may be moved when it is in an open position along the rail for example to completely uncover the space between the gantry and one end wall.  Two hoods are advantageously employed, each of which is movable along the rail When they are positioned in an opened position but only alternatively.  When they are in a closed position an actuator lifts the side wall of the hood upwardly to move the casters off the rail and to move the side wall inwardly toward the edge of the floor into a closed position.

Abstract: SEISMIC ACTUATION SYSTEM            ABSTRACT OF THE DISCLOSURE          A seismic actuation system incorporating a plurality of motion sensors.  The motion sensors included a housing in which a weight is supported for slidable movement along a single direction within the housing.  The sensors are mounted to a horizontally disposed enclosure.  The sensors are arranged so that the directions of travel of the weights within the enclosures are uniformly arranged so that vibration of sufficient magnitude in the horizontal plane will cause one or more of the weights to move.  By adjusting the mass of the weights, the sensitivity of the sensors can be adjusted. When a seismic event of sufficient magni-tude occurs, the weight becomes displaced from a central position within its housing and moves to one or the other end of the housing to activate the contacts. Activating the contacts completes a circuit so that one or more warnings, such as bells, lights, or spoken words, are produced or one or more safety devices are actuated.
