Abstract: MOTORIZED POOL COVER                 ABSTRACT OF THE DISCLOSURE A pool cover is alternately reeled on the spool and drawn across the pool by a mechanism in which a motor-driven shaft reels in a cover sheet to uncover the pool and the free end of the sheet is pulled by cords reeled onto drums connected to the driven shaft to cover the pool.  The cords are reeled around the drums in the opposite direction from which the sheet is reeled around the spool, and the cords are entrained around direction-reversing pulleys at the opposite end of the pool, an arrangement which results in the cord being reeled on the drums as the sheet is paid out from the spool and vice-versa.  The cord velocity and cover sheet velocity are attempted to be matched and held constant by winding the cords onto from a conical cord drum for the cords. The cord is guided precisely onto and from a given diameter portion on the conical drum by a cord carriage.         It is preferred to try to obtain a constant and uniform tension on the opposite beaded edges of the cover sheet and on the cords on opposite sides of the pool to prevent slack from developing in the cover sheet or cords.  Herein, biasing means for the spool and the cord drums are provided in the form of torsion springs that connect the spool and cord drums to the shaft.  The torsion springs coil or uncoil to adjust somewhat the speeds of spool rotation and drum rotation with respect to the rotational speed of the shaft.  The interconnection of the spool torsion springs and drum torsion springs maintain the sheet and cords under continuous tension.         Limit switch means in the form of magnetically actuated switches along the side of the pool are actuated by magnets carried by the cover sheet to stop reel-in or pay-out of sheet at the fully covering or fully uncovering positions of the sheet.

Abstract: LASER HETERODYNE INTERFEROMETRIC METHOD AND SYSTEM FOR MEASURING     ULTRASONIC DISPLACEMENTS               Abstract of the Disclosure The invention is concerned with a laser hetero-dyne interferometric method and system for measuring the displacement of a free surface of a material subjected to ultrasound.  A laser beam having a predetermined in-tensity is generated and then divided into first and second beam portions having respective intensities re-presenting minor and major fractions of the predetermined intensity, the first beam portion being angularly dis-placed relative to the second beam portion and being frequency shifted by a predetermined frequency.  The second beam portion is passed through an optical lens off-center thereof to focalize the second beam portion onto the free surface of the material subjected to ultra-sound, thereby scattering same.  The scattered second beam portion is combined with the first beam portion to obtain an optical fringe signal which is converted into an electrical fringe signal comprising a central peak at the predetermined frequency and a sideband on either side of the central peak.  The electrical fringe signal is thereafter processed through circuitry means without de-modulating a phase modulation produced by ambient vibra-tions, to extract a signal proportional to the displace-ment of the free surface.

Abstract: Abstract Of The Disclosure A downhole tool apparatus has a housing with a compression chamber defined therein.  A fill passage is disposed through the housing for placing the compression chamber in open flow fluid communication with a well annulus exterior of the housing so that well fluid may flow into the compression chamber as the apparatus is lowered into a well.      An isolation valve is provided for selectively closing the fill passage and thereby trapping well fluid in the compression chamber.  An operating element is disposed in the housing.  An actuating piston is slidably disposed in the housing and is operably associated with the operating element for operating the same in response to movement of the actuating piston relative to the housing.  The actuating piston and housing are so arranged and constructed that movement of the actuating piston relative to the housing changes the volume of the compression chamber and of any well fluid trapped therein.  The volume of the compression chamber is sufficiently large that an equal volume of water containing no absorbed gases would have a volume decrease when subjected to a pressure increase equivalent to a prede-termined operating pressure of the actuating piston means, at least as great as the decrease in volume of the compression chamber when the actuating piston is moved bet-ween first and second positions thereof relative to the housing.
