Abstract: TIRE RETREADING SYSTEM          Abstract of the Disclosure Tire casings are retreaded with precured tread strips in a heated pressure vessel provided with pressure connections which effect simultaneous inflation of the tires and pressurization of the vessel while maintaining tire pressure above vessel pressure.  Subsequently a pressure relief system permits the tires to exhaust faster than the vessel.  Each tire is prepared for retreading by applying a bonding medium between the tire periphery and the retread strip and wrapping the resulting assembly with a fluid impervious flexible cover.          Tread stabilization rings, wick material and non-stick polymer film may be inserted between the tread strip and the cover.          The improvement according to the invention also comprises interposing between the tread strip and the cover, a thin, flexible perforated film of synthetic polymeric material which causes the flexible cover to slide against the surface of the tread strip and to thereby penetrate into the tread grooves so as to conform with the tread profile.  A further improvement comprises interposing between the tread strip and the cover, at a location of the connection between the exhaust conduit and the cover, a pad of porous fabric which is stretchable in two directions to thereby aid in releasing air from the space.

Abstract: ABSTRACT                  A method for automatically controlling the restrictors in a ram-tube type refuse compacter or pelletizer. Variable restrictors near the discharge end of the tube control the compaction pressure exerted on the refuse as it is forced through the tube. The restrictors are capable of being moved inward and outward on each ram stroke in response to changes in the ram pressure required to advance the compacted refuse through the tube. The method comprises:                (1) measuring the ram pressure during the last smallest practicable increment of forward ram travel, (2) adjusting the restrictors slightly inward if the pressure measured in step (1) is less than a predetermined pressure P1, (3) measuring the ram pressure when the ram is at the lock-out point, normally about 6' from the forward end of its stroke.                (4) overriding step (2) by making no inward restrictor adjustment if the pressure measured in step (3) is less than a predetermined pressure P3, (5) measuring the ram pressure during at least the last smallest increment of forward ram, and (6) adjusting the restrictors slightly outward if the pressure measured in step (5) is greater than a predetermined pressure P2.

Abstract: ABSTRACT OF THE DISCLOSURE     The principle of operation of apparatus according to this invention is based upon interrogating the image of the target to be ranged at a selected spatial frequency.  The image modulation at the selected spatial frequency will only be a maximum when the image is in sharp focus.  The region of possible points of focus is interrogated by a lined grating which oscillates relative to said region in order to determine the point in the region at which the image modulation has its maximum value.  The point of focus thus determined provides an indication of the range of the target.

Abstract: Cases 5791, 5916, 5917, 5918 EARLY CRACK DETECTION          Abstract Early detection of cracks in non-permeable, structural members subject to stress is effected before the cracks traverse the member by:     (a)  forming a cavity in the structural member or adjacent thereto such that a crack forming in the structural member provides a passage for a fluid to flow between the environment and the cavity without passing through the entire structural member, (b)  sealing a fluid passageway in fluid communication from the cavity to a source of pressure different than ambient pressure at the structural member and to a pressure sensor, (c)  imparting a higher or lower pressure to the cavity and the fluid passageway, and, (d) monitoring the internal pressure in the cavity and fluid passageway with the pressure sensor, such that a crack in the structural member penetrating to the cavity allows passage of fluid between the environ-ment and the cavity and is thus detected by the pressure sensor.  The apparatus and process is particularly appli-cable to early detection with vacuum of cracks in the heat affected zone adjacent to welds on critical stressed members of an offshore platform.  A strain guage system may be employed in conjunction with the crack detection system.

Abstract: ODD-SHAPED CONTAINER INDEXING STARWHEEL     ABSTRACT OF THE DISCLOSURE         Indexing mechanism for multiple station glassware inspection machines in which a plurality of pocketed star-wheels are used.  One set of pockets are formed with con-tainer encircling or restraining members which open and close in response to the contour of a box cam.  The encircling means loosely retains containers so that they may be rotated about their vertical axes while held in a specific location.  The finish of the containers is guided by an upper starwheel having pockets of a size commensurate with the size of the finish of the container.  The containers to be inspected are brought into the starwheel with the encircling means opened.  Upon closing. of the encircling means, containers may be indexed through a series of positions where they may be inspected for various defects.          Prior to arriving at the position where the containers are to be taken from the starwheel, the containers are oriented with their generally long, horizontal axes normal to the direction of movement of the conveyor for taking containers away.         This apparatus permits rotation of non-round con-tainers while still retaining the containers in a sufficiently precise location so as to permit both mechanical and optical inspection of various portions of the  container.
