Abstract: A tape transport assembly typically employing a belt drive for the tape comprises:A. a pair of reels for tape to be transported from a supply roll on one reel to a take-up roll on the other reel,B. at least one peripheral support to peripherally engage one of said reels to position same upon initial reception thereof in said assembly, andC. centering support means carried by the assembly for relative movement into and out of centrally supporting position in which said one reel is displaced out of peripheral engagement with said peripheral support and is centrally supported for rotation.

Abstract: A helmet retention system including a forwardly facing helmet comprises,A. left and right side retention strap sections, the left section having attachments to the helmet at forward and rearward locations, and the right section having attachments to the helmet at forward and rearward locations, the sections hanging from the helmet,B. left and right sliders respectively slidably attached to the left and right retention straps to be adjustably slidable therealong, andC. chin strap means having attachment to and hanging from the sliders to extend therebetween.

Abstract: Composition for a clear blue colored, stabilized liquid peroxygen bleach, suitable for household laundry use on all fabrics, whose coloring dye is rendered non-substantive to natural or synthetic fibers by the inclusion of a non-ionic surfactant as an anti-dyeing agent having an HLB value within a predetermined range.

Abstract: Method and apparatus for bottom hole testing in producing or injection wells under pressure employing a tool adapted to be lowered on a flexible line to sampling depth in a well, the tool including a first section containing a closed sample chamber detachably connected to a second section containing time delay fluid escapement means operable to maintain the closed condition of the chamber until the sampling depth is reached and to then cause entry of a well fluid sample to the chamber followed by its closure to retain the sample and preserve the well pressure at the sampling location, the method including withdrawing the tool from the well, disconnecting the sections to recover the sample chamber independently of the second section, and transferring and opening the chamber for testing of its well fluid content.

Abstract: Unitized fireplace heat deflector comprising upper and lower sheet metal panels relatively angularly variable along a common hinge, the panels being mountable to the side walls of a fireplace opening by longitudinally adjustable terminal bearing rods at the top and bottom of the panel assembly.

Abstract: Equipment for cleaning metal or plastic parts by immersion in a tank-contained agitated liquid cleaning solution in which the parts are loaded into open side cages mounted on a powered carrier wheel immersed in the solution and having interrupted rotation to carry the parts from a loading station at one side of the carrier above the solution downwardly therethrough and upwardly to an unloading station at the opposite side of the carrier, the tops of the cages being slotted to accommodate mechanical displacement of the parts through the cages and the tank containing stationary barriers blocking movement of the parts through the open sides of the immersed cages.

Abstract: A solid product for rub-on application to stains and soil deposits on fabric preparatory to laundering, comprising blended water soluble non-ionic detergent and stable laundry enzyme uniformly dispersed therein, and the method of manufacturing the product.

Abstract: A flaw penetrant test panel having a sheet metal surface in which are impressed tiny or microscopic flaw simulating cavities distributed over the test surface to receive one or more penetrants being tested, the mouth size of the cavities being in the range of about 1 to 10 thousandth inch and being formed by heating the metal to incipient softening temperature followed by penetration of the surface test area using a needle-like tool proportioned to the desired cavity size and depth and which upon penetration of the metal displaces it in a crater-like rim about the cavity being formed.
