Abstract: GUN SIGHT POSITIONING MECHANISM            ABSTRACT           A gun sight positioning mechanism (22) disclosed includes a parallelogram linkage for moving a gun sight positioning shaft angularly with a trunnion shaft (32) on which a gun is supported and has a slip clutch (44) that connects the linkage to one of the shafts so that the sight can be aimed downwardly at the target area while the gun remains aimed upwardly along the projectile path.  Preferably, the slip clutch connects the linkage to the gun sight positioning shaft and includes a stop (56) that allows the sight to be aimed upwardly back into alignment with the gun after viewing the impact.  First and second links (46,52) of the linkage are respectively connected to the trunnion and sight positioning shafts and interconnected by a connecting link (54) whose length is adjustable to insure the proper angular movement of each shaft with the other.  A mount of the slip clutch has a flanged end secured to the sight positioning shaft and a distal end on which a handle (58) is secured to provide the pivoting of the sight shaft independently of the gun.  A spring washer of the clutch biases  a  brake member thereof against the second link which is thereby engaged with the flanged end of the mount to provide the slip clutch action.

Abstract: Title of the Invention FOLDING RAIL CAR DOORS                Abstract of the Disclosure A rail car having an interior cavity defined partially by vertical rail car side walls and a roof structure with an inwardly and upwardly directed portion to improve car clearance is disclosed.  Access to the cavity for loading and unloading lading is through an end opening.  A pair of door assemblies, each of which includes a plurality of panels, each panel of which is pivotally movable with respect to the others, are in-cluded for closing the end opening.  Pivot means for mounting each of the door assemblies are provided to move the door assemblies between their respective folded open positions and unfolded closed positions.  The pivot means are mounted for movement toward and away from the interior of the rail car to permit storage of the folded door assemblies within the rail car along the car side walls. Top panel portions extend front the top of the door as-semblies angularly inwardly relative to the opening and in spaced relation with each other and the roof structure. The angle of the top panel portions, the space between each of the top panel portions and every other top panel portion and the spacing of the top panel portions from said roof structure all being of such magnitude that when said door assemblies are in the unfolded closed position, the end opening portion above the door assemblies is substantially closed, and when the panels are pivotally moved from the unfolded closed position to the folded open position and to storage along the rail car side walls and back, each of the top panel portions clears every other top panel portion and the roof structure sufficiently for movement relative thereto.

Abstract: UNINTERRUPTIBLE POWER SUPPLY       WITH LOAD REGULATION OF STANDBY VOLTAGE SOURCE            Abstract of the Disclosure The present invention relates to an uninter-ruptible power supply.  The power supply is comprised of an input to accept an AC power source.  A controlled ferroresonant regulator is coupled to the input and energized by the AC power source.  A rectifier is coupled to the ferroresonant regulator to derive a first rectified DC voltage therefrom.  An inverter is energized by the first rectified DC voltage.  An output unit is provided to accept a load energized by a second rectified DC voltage output of the inverter.  A voltage sensor is coupled to sense a voltage of the load and to a ferro-control to control the controlled ferroresonant regulator and to regulate the second rectified DC voltage output of the inverter at a first magnitude level by controlling a DC level of the first rectified DC voltage.  A voltage regulation circuit is provided which includes a second input adapted to accept a reserve DC voltage source and an output unit to couple it to the inverter.  The voltage regulation circuit responds to the voltage sensor when the voltage level of the second rectified DC voltage output drops below the first magnitude level and is operative to amplitude modulate and couple a voltage level supplied by the reserve DC voltage source to the inverter and to control a DC voltage level of a voltage applied to the inverter level so that a third rectified DC voltage output of the inverter at the load is slightly lower in magnitude than the first magnitude level of the second rectified DC voltage output occurring at the load.  This is accomplished in response to the controlled ferroresonant regulator.  As a result, a failure of the primary power source enables the voltage regulator circuit to insure a continued DC voltage at the load.

Abstract: SCANNING MIRROR ARRANGEMENT                          Abstract An image forming scanning mechanism without obsuration in its optical path comprises first and second reflectors that are pivotally actuated about respective orthogonal axes. The scanning reflectors are positioned so that radiant energy in a first optical path from an object field impinges upon a vertical-scan reflector where it is directed to a horizontal-scan reflector and whereupon it is directed back onto the vertical-scan reflector from whence it is reflected along a second optical path in a different plane from the first optical path.  The pivotal axes of the vertical-scan reflector and the horizontal-scan reflector are perpendicular to path of radiant energy reflected therefrom.  A detector is positioned to receive radiant energy from elemental areas of an object field. The orthogonal disposition of the first and second pivotal axes provides a distortion free image signal from the detector that is comparable with the x-y scan pattern of conventional television display circuits.
