Abstract: ABSTRACT  OF  INVENTION      The invention relates to hydraulic jack operating systems.    The end-of-stroke damping of the jack is produced by an element of the shape of a truncated cone, integral with the stem of the jack, which penetrates into a floating ring and which defines, in this ring, a damping chamber isolated from the remainder of the capacity of the jack   When the stem of the jack makes its return move-ment, the chamber is re-supplied with oil through passages which were previously obturated by the displacement of the ring at the instant of the damping.    The invention is applicable to high speed hydraulic controls for circuit breakers with ultra-rapid operation.

Abstract: UNITED STATES PATENT APPLICATION          OF:  Jack E. Prince, Franklin E. Terry and William H. Mullins FOR:  AEROBIC TYPE SEWAGE DIGESTION SYSTEM                          ABSTRACT    The present invention is a system for treating sewage waste commonly called sludge.  An aerator shears the solid particles while simultaneously adding oxygen to the sludge.  After being pumped through the aerator, the sludge exits into a large tank.          The sludge in the tank is continually circulated, drawn from the bottom of the tank and pumped through the aerator.  As additional sludge is periodically added, supernatant water is removed through an overflow line of a stilling well in the center of the tank.          After a lengthy period of time, part of the sludge in the bottom of the tank will be withdrawn and moved to the drying beds.          With some modifications, existing anaerobic systems may be changed to the present aerobic system for a much greater capacity.  Entire collection and waste treatment plant facilities may be designed utilizing the aerators at various stages.

Abstract: HINGE                   Abstract A hinge comprises a first and a second bracket that are at least partially spaced apart.  A viscoelastic member is disposed between and secured to the brackets to permit relative rotation between them about an axis that passes through both brackets and the viscoelastic member.  At least one of the brackets includes a stop engagable with the other bracket to prevent rotation of the first bracket relative to the second bracket about the axis of rotation in one direction beyond a predetermined relative orientation of the two brackets.  Relative rotation between the brackets when the stop is engaging the other bracket occurs about a second rotational axis spaced from the first axis and passing through a point of contact between the stop and the other bracket.

Abstract: ABSTRACT     A system is provided for scanning a laser beam across the width or fabric material to be inspected.  A scanning mirror receives coherent light from the beam and is mounted to repeatedly swing through a given scan angle.  An optical arrangement of mirrors in side-by-side relationship receives the light beam from the scanning mirror and directs it in successive site-by-side parallel directions or channels towards the fabric to irradiate successive areas of the fabric across its width.  A de-scanning mirror is mounted to repeatedly swing through the same given scan angle in synchronism with the scanning mirror and a second optical arrangement of mirrors in alignment with the first mentioned mirrors receives the beam after passing through successive areas of the fabric and directs it to the de-scanning mirror.  The beam reflected from the de-scanning mirror in turn can then be analyzed.

As a result of such third lens, the light beam reflected from the second record carrier surface can be continuously directed at the light detector irrespective of the movements of the second record carrier surface toward and away from the second lens even when the axis of the light beam incident on the second lens deviates from the optical axis of the latter.
