Abstract: ABSTRACT OF THE DISCLOSURE          A knock-out tool for use with a coiled tubing string consists of a relatively large diameter central portion with a reduced diameter upper portion extending upwardly and being connectable to the lower end of the tubing string.  A similar reduced diameter lower portion or spear extends downwardly from the underside of the center portion.  The center portion centers the tool in the casing so that the spear enters the packer in the well casing and knocks out the removable plug.          The tool is longitudinally apertured or drilled so that com-pressed air or gas can clear away sand or the like from the top of the packer as the tool approaches the packer. A shoul-dered ring or collar is detachably secured for limited sliding movement upon the spear adjacent the center portion of the tool and when the ring strikes the top end of the packer, the pin is sheared.  When withdrawn to the surface, the fact that the pin has been sheared indicates that the spear has entered the packer and dislodged the detachable plug.

Abstract: Boltswitch - Case 103 DUAL SWITCH OPERATOR USING MODIFIED         GENEVA MOVEMENT                      ABSTRACT OF THE DISCLOSURE            A dual switch actuator mechanism  for coordinated actuation of two high-current switches, each of which includes a switch operator mechanism for opening and closing the switch in response to rotation of a switch operator shaft.  The switches are mounted adjacent to each other with their switch operator shafts in aligned paraxial spaced relation.  The dual switch actuator mechanism includes a rotatable main shaft positioned between and in aligned paraxial relation to the switch operator shafts.  A Geneva drive plate having an arcuate bearing   surface is affixed to the main shaft; two drive pins are mounted on the drive plate.  Two modified Geneva follower plates are provided, each affixed to one of the switch operator shafts.  Each follower plate has a drive slot for receiving one of the drive pins and an arcuate bearing surface which is complementary to the drive plate bearing surface.  For a given neutral position of the main shaft, each drive pin is positioned in the entrance of a follower plate drive slot and the bearing surfaces of both follower plates engage the drive plate bearing surface.     Rotation of the main shaft through a predetermined angle in either direction from the neutral position causes one guide pin to move inwardly of the drive slot of one follower plate, rotating the follower plate and its associated switch operator shaft to actuate one switch without actuation of the other.

Abstract: 1950-92a ABSTRACT OF THE DISCLOSURE    A circumferentially complete seal is received in a circumferentially complete groove machined into a surface of a first member forming part of an ionography imaging chamber.  The surface of the first member is separated from a surface of a second member of the imaging chamber by a clearance which normally connects the interelectrode gap of the imaging chamber with the atmosphere.  The seal has an inflatable elastic inner section adjacent to the bottom of the groove and a reciprocable second section which resembles a plunger and is moved from the groove, across the clearance and into sealing engagement with the surface of the second member in response to inflation of the first section.      The latter contains a strip-shaped connector which is bolted to the first member to deform a portion of the first section into sealing engagement with the surface at the bottom of the groove.      The second section is also a tube which contains a reinforcing insert and has a sealing lip adjacent to the interelectrode gap and sealingly engaging the surface of the second member in response to inflation of the first section.  The width of the second section exceeds the width of the clearance and the thickness of the second section is at least twice the width of the clearance.      When the first section is deflated, the width of the seal is slightly less than the width of the groove.

Abstract: ABSTRACT   There is disclosed a soft, hydrophilic plastic corneal contact lens, comprising a substantially circular optical correction zone which is shaped for the correction of astigmatism.  The lens is soft enough to tend to conform to the shape of the cornea when placed on an eye with corneal astigmatism.  The lens comprises at least one discrete lug or flange extending from the periphery of the correction zone, the lug having a radial width measured from the periphery of the correction zone which is less than the radius of the correction zone. The lug is adapted to engage the sclera of the eye, adjacent to the cornea, at one of the depressions on the eyeball formed between the four rectus muscles attached to the sclera of the eye, to thereby prevent rotation of the lens to maintain the required astigmatism correction.
