Abstract: RADIAL FORCE ANTI-EXTRUSION DEVICE    FOR SEALED DRILL STRING UNIT Abstract of the Disclosure A drill string reamer-stabilizer includes a main body adapted to be connected as an element of a rotary drill string.  Individual bearing shafts are mounted axially along the exterior of the main body to support roller cutters that engage the wall of the borehole.   Seal units are positioned around each bearing shaft between each roller cutter and bearing shaft to define a lubricant space;.  The seal units retain lubricant in the lubricant space and prevent contami-nating fluid and materials in the borehole from entering the lubricant space. At least one seal unit comprises an annular cup-shaped elastomer seal member mounted in an annular seal gland in the roller cutter.   The seal gland has an inner side adjacent the lubricant space and an outer side exposed to the fluid and materials in the borehole.  An annular spring member sits in the cup-shaped elastomer seal member and maintains the seal member spaced from the outer side of the seal gland so that internal pressure in the lubricant space  is vented outward past the seal member but external pressure of  fluid and materials in the borehole forces the seal member against the inner side of the seal gland creating a fluid tight seal.

Abstract: On sait que la réalisation d'un dispositif permettant la circulation d'un fluide est d'autant plus difficile à effectuer que la température de fonctionnement du dispositif est élevée. Au-dessus de 1400 degrés Kelvin (K) environ, les céramiques s'imposent, mais les techniques de fabrication ne sont pas aussi aisées que dans le cas de métaux et de graves problèmes d'étanchéité et de réalisation se posent. Dans la présente invention, les conduits de fluide sont inclus dans la masse de la céramique, ce qui permet d'éviter l'emploi de joints d'étanchéité et de faire en sorte que l'étanchéité ne dépende plus que de la porosité du matériau lui-même. Dans la présente invention la fabrication du dispositif comprend trois étapes: fabrication d'éléments non totalement frittés, assemblage,et frittage de l'assemblage. Un tel procédé permet la réalisation de dispositifs complexes.

The carton blank has a front panel, a bottom panel, a rear panel, a cover panel, and a front cover sealing flap articulated one to the other in the order named, with end-forming flaps and glue-flap extensions extending later-ally therefrom adapted to be glued together to form inner and outer walls and side-cover flaps.  The bottom outer wall-forming flap is glued to the inner wall-forming flaps by glue strips along the side edges of the latter, where they are joined to the front and rear panels, and the side-cover flap has a tuck-in tab adapted to be tucked in under the bottom outer wall-forming flap between the glue strips.  The glue-flap exten-sions are adapted to fold over the side-cover flaps and to be glued thereto by an extension of the glue strip adjacent the front of the carton.  In forming the carton or package, one end is closed first by folding in the side flap extensions, folding down the side-cover flap, applying the glue strips with the one adjacent the front or the carton extending up over the folded-down side-cover flap, then folding up the bottom outer wall-forming flap to a position overlying the tuck-in tab and folding in the glue-flap extensions over the glue strip on the side-cover flap and causing adherence between the glue and the folded-in flaps.  The tube thus formed is then filled and the other end closed in a like manner.

Abstract: ABSTRACT        A pressure responsive, variable resistance, analog switch has first and second conductors interleaved in spaced-apart relationship and disposed on a base member.  An insulative spacer ring is positioned around and rises above the first and second conductors.  A resilient cover sheet is attached to the top of the insulative spacer ring in spaced relationship over the conductors to define an enclosure between the resilient cover sheet and the base member.  A pressure sensitive resistive conductor composition is disposed on the resilient cover sheet or on the conductors in the enclosure to interconnect a resistance between the first and second conductors when the resilient cover sheet is depressed against the conductors.  The amount of resistance so interconnected varies inversely to the amount of pressure exerted.

Abstract: ABSTRACT     Two separate but identically shaped sections cooper-ate to form an electrical cord gripping device when they are brought together.  The sections are insertable into recesses in cooperating halves of an electrical housing, by wedging or snapping them into place, and, when the housing is closed, the sections form a restricted opening and provide a clamp around an electrical cord passing through the opening and into the housing.          The sections are readily removable from the housing, so that a single housing can be used with electrical cords of different sizes.  Further, each section contains a diagonal rib, and, when the sections are brought together, their ribs criss-cross one another to grip the cord from opposite sides.  The sections are also shaped to provide abutting surfaces which overlap each other to cam the sheathing of the electrical cord into the open-ing provided by the sections, and prevent crimping of the sheathing.

Abstract: ABSTRACT OF THE DISCLOSURE         In order to limit the dispersion into the air of fines during the processing, handling and transport of fines-contain-ing material, a hollow plow-like member is employed to insert the fines onto a conveyor belt well below larger particulate matter being conveyed by the belt.  The plow-like member has a generally narrow V-shaped cross section, and the sidwalls flare outwardly at its lower terminus.  The plow-like member is positioned just above the belt surface and is oriented with its leading edge facing the direction of material flow.  Thus, the larger particulate matter lumps are lifted and folded back from each side of the plow-like member's centerline to define a space into which fines can be inserted through the tool interior.    After the larger particulate matter lumps pass the member trail-ing edge, they fall back toward the belt center and cover the deposited fines.
