Abstract: ABSTRACT        A snare-type animal trap is characterized by a spring noose-actuating spring arm which pivots well in excess of 90° from its set to its sprung positions.  The spring arm is bent slightly to add to its effective sprung position angle.  In a leg snare embodiment, a noose cable guide at the distal end of the spring arm includes a narrow surface from which two upwardly projecting bent guide members extend to define a slot for slidably guiding the cable.  The cable is anchored at one end and has a noose formed at its free end by means of a slide member having two through-holes slid ably surrounding the cable.  A washer precludes passage of the free end of the cable through the first hole which is aligned with a channel defined between two fingers formed at the bifurcated end of the slide member.  The fingers are curled back toward the first hole so that the cable can slidably pass through the first hole, the channel, and then through the second hole to form the noose.  The channel formed by the curled fingers prevents the cable from pivoting when the trap is actuated and forces the noose to rise vertically.

Abstract: FECAL INCONTINENCE DEVICE                       Abstract A fecal incontinence device in the form of an elongated collection bag having an attachment ring about an opening at one end of the bag.  The ring is formed of a soft, pliable, and stretchable closed cell thermoplastic foam, and the bag is formed from a single sheet or film of thermoplastic material that, following its attachment to the ring, is folded to provide a pair of side panels extending at right angles to the plate of the ring, such panels then being heat sealed to each other along their margins to define the finished bag.  The foam attachment ring has its surface coated with a pressure-sensitive adhesive, and its inner and outer margins are non-concentric to define. a relatively narrow perineal attachment zone.  A plurality of release sheet sections cover the adhesive coating of the ring and are sequentially removable to facilitate elective attachment of the ring to a patient.  The bag is also provided with a protected gas vent and a self-closing passage for the insertion of a thermometer or other medical instrument.

Abstract: ABSTRACT OF THE DISCLOSURE     An improved aqueous acidic trivalent chro-mium electrolyte and process for increasing the toler-ance of such electrolytes to the presence of deleteri-ous contaminating metal ions which normally progres-sively increase during commercial operation of the electrolyte ultimately resulting in chromium electro-deposits which are commercially unsatisfactory due to the presence of streaks, clouds and hazes in the de-posit.  The improved composition contains controlled effective amounts of thiazole  or benzothiazole com-pounds which are effective to mask the adverse effects of such contaminating metal impurities and which also enhance the codeposition of such metal contaminants on the parts being plated thereby reducing, and in some instances preventing the progressive accumulation of such contaminating metal ions in the electrolyte.          The invention further encompasses the process of reju-venating trivalent chromium electrolytes which have been rendered deficient in their ability to deposit satisfactory chromium platings by a controlled addition of such additive agents followed by electrolyzing of the electrolyte to progressively reduce the concentra-tion of contaminating metal ions to a level in which satisfactory performance of the electrolyte is restored.

Abstract: DRILL STEM TEST AND PERFORATING SYSTEM  ABSTRACT    A pipe string with a valve, pressure responsive means, packer, firing mechanism and perforating gun are suspended within a well to test a formation.  The packer is set to form an upper and lower annulus, and the valve and pressure responsive means are disposed above the packer in the upper annulus.  A force transmission means extends from the pressure responsive means to the firing mechanism in the lower annulus.  The valve is ini-tially closed to prevent fluid flow through the flow bore of the pipe string.  The upper annulus is pressurized to open the valve and create a pressure differential across the pressure responsive means.  The pressure responsive means then transmits a force through the force transmission means to the firing mechanism to actuate the firing mechanism and detonate the perforating gun.          Fluid from the formation then flows through the perforations and up the flow bore of the pipe string to the surface.

Abstract: Abstract:         A video tape recorder uses pilot signals.  Deviation between a video track on the magnetic tape and a rotating head during a tape stopped condition of an intermittent drive for a noiseless slow-still picture is corrected.  A series of pulses from a frequency generator of a capstan is counted during the tape feeding condition of the intermittent drive, in order to detect the timing of stopping of the tape feeding.        As this count number becomes a set value corresponding to a regular amount of feeding of the tape during the inter-mittent drive, the tape feeding is controlled to stop it.  A tracking error signal is produced from the pilot signals reproduced from the tape by the rotating head during the tape stopped condition.  The set value for the next feeding of the tape is corrected in response to this tracking error signal.          The invention has the advantage of enabling ready synchroni-sation in a system using pilot signals on the video track.

Abstract: ABSTRACT OF THE DISCLOSURE A tire building drum is described as having, a plurality of radially movable bead lock segments at each end of the drum for holding the tire bead rings during the turn-up operation, a pair of turn-up bladders, and a pair of carriers which work in conjunc-tion with the bead lock segments and turn-up bladders to tension the ply endings of the unvulcanized carcass ply or plies as the ply endings are turned up and reversely wrapped around the tire bead rings to anchor the rings to the unvulcanized tire carcass for further processing.  The carriers span the bead seats of the bead lock segments and snugly fit around the adjacent turn-up bladders, so that the bead lock segments, upon radial expansion, pull against and distort the shape of the bladders which react to regain their shape and/or position by pushing back against the carriers to tension the carriers which are in contact with the ply endings and which tension the ply endings during turn-up to eliminate, adjacent the tire bead rings, the formation of voids which entrap air and adversely affect the adhesion between the tire bead rings and surrounding rubber material.  A lubricant is provided between the contacting surfaces of the carriers and turn-up bladders to permit relative, unimpeded movement between these two components.
