Abstract: SELF-ADJUSTING BREATHER BAG                 Abstract of the Disclosure A self-adjusting breather bag for use in sealed storage structures to limit the contact of ambient atmosphere with the stored material.  The self-adjusting of the lower part of the bag to a higher position in the structure is accomplished by strategically assembling elastic or resilient members inside or outside the bag which automatically raises the lower portion of the bag when the bag is in a substantially non-inflated condition and allow the bag to expand in an inflated condition.  A retracting device may be used to store the elastic or resilient members to provide for a greater range of inflation and retraction of the bag.

Granted: 1982-05-04
Abstract: ABSTRACT OF THE DISCLOSURE    This invention relates to a self-contained emergency lighting fluorescent pack which is mountable to a fluorescent fixture by being placed in-line with a fluorescent lamp having a length shorter than that normally installed in the fluorescent fixture.  It may alternatively be mounted in a side-by-side relationship near one of the fluorescent lamps used in the fixture.  The emergency fluorescent pack includes a safety cradle which is positioned on the fixture 50 as to prevent energization of the fixture if the fluorescent lamp lit by the pack during power outages is improperly installed in the fixture.  the fluorescent pack further includes a high frequency ferro-resonant transformer having operating characteristics that provide for energizing a lamp from batteries within the pack without the need for heating the lamp filaments and without the need for an external ballast.          The disclosed emergency lighting fluorescent pack is useful in any building using fluorescent fixtures there it is desired to have illumination during power outages.

Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus for computerized axial tomography (CAT) image reconstruction applicable to X-ray scanning of the human body. Successive series of calculations determine the values of a characteristic in defined segmented areas of an examination plane.  A reduction in the time and equipment requirements for reconstruction calculations may thereby be effected.   Images representative of the difference between the value of the characteristic at a reconstruction point and the average value of the characteristic in adjacent regions (.DELTA.u) may be calculated and dis-played from measurements taken within a localized contiguous region of the examination plane.  Radiation dose to patients and computation time in X-ray computerized axial tomography scanning systems is thus reduced.          Differential displays of the type described may be adjusted to image boundaries, in which case they do not suffer from gray scale resolution problems which are typical of prior art displays.

Abstract: ABSTRACT     The rotary control valve has a casing defining a receptacle therein.  The casing has a main axis and spaced flow ports which communicate with the receptacle through a fluid flowway.  A flow-control member is rotatably disposed within the receptacle.  The member has a body which is shaped to fit said receptacle and which defines an axial bore opening through the outer wall of its body, whereby, in use, the opposite open ends of the bore are in register with the flow ports when the control member is in its fully-open position   The wall of the member's body has a pair of elongated orifice slots extending circumferentially of the body in opposite directions, generally from the opposite open ends of the wall of the bore.  Each of the slots is defined by converging walls.          The body has non-slotted closure portions between the trailing ends of the orifice slots and the adjacent ends of the bore.  The closure portions are adapted to close off the flow ports in the flowway-closing position of the control member.  The improvement resides in that the body has a silencing chamber surrounding the wall of the bore, and silencing means are disposed in the silencing chamber.

Abstract: ABSTRACT OF THE DISCLOSURE         An annulus is integrally rotatable with a shaft. First and second pistons are disposed between the shaft and the annulus in diametrically opposed relation.  A plu-rality of pistons are circumferentially spaced around the annulus and are sequentially supplied with high pressure hydraulic fluid to exert driving force on the annulus and shaft in proportion to the eccentricity of the annulus. High pressure fluid is selectively applied to one of the first and second pistons, to shift the annulus and thereby vary the eccentricity thereof and the motor speed and torque.  A pair of diametrically opposed, semicircular shoes, are retained by the shaft and movable perpendicular to a direction of movement of the first piston.  An inner end of the first piston is formed with a circular cutout. In response to high pressure applied to facing surfaces of the shoes, the shoes move away from each other and abuttingly prevent the first piston from moving closer to the shaft beyond a limit position.  In response to low pressure applied to the  facing surfaces of the shoes, the shoes move toward each other and fit inside the cutout. Thus, the first piston is allowed to move closer to the shaft than the limit position.  This arrangement provides a three speed radial cylinder hydraulic motor.
