Abstract: INTEGRAL ELECTRICAL CONTACT AND     METHOD OF MAKING SAME        ABSTRACT            An integral electrical contact (10, 110, 210) and a method for making the electrical contact is dis-closed.  The contact includes an elongated electrical conducting base portion (19, 119, 219) which has an axial passage (29, 129, 229) extending therethrough and also includes several axially aligned electrical wires (20, 120, 220) integrally formed with the base portion. The wires are axially aligned with the passage of the base portion and extend beyond a first end (18, 118, 218) of the base portion.  Each of the wires which extends beyond the first end of the base portion in-cludes an end portion (24, 124, 224) that terminates in an acutely angled surface.  The electrical contact is made by coining an electrically conductive flat sheet of material (12) to form a plurality of elongated raised design portions (14, 16, 114, 116, 214, 216) which are axially aligned and extend inwardly from one end surface (13) of the sheet.  The design portions are separated by slitting the sheet between the design portions or by further coining the sheet to form the wires.  A bevel is placed on the ends of the wires at the end surface of the sheet before the wires are slit apart.  The sheet is then rolled so that the wires are axially aligned and adjacent to each other.

Abstract: TITLE          TIRE TRACTION DEVICE          ABSTRACT OF THE DISCLOSURE         A traction device surrounding the tread and sidewals of a tire.  The device includes several elongated, molded plastic traction members having fastening strips secured to opposite ends.  The traction members are secured about the periphery of the tire by a flexible belt or strap extending through the fastening strips at opposite sides of the tire so that the traction members extend across the tire tread from one side of the tire to the other.  The traction members have a generally planar outer face.  The inner face is formed with a plurality of suction cavities surrounded by sidewalls which abut the tread surface of the tire.  A plurality of relatively small apertures extends from the suction cavities outwardly and communicate with recesses formed in the planar outer face of the traction members so that as the tire rolls along a road causing the traction members to sequentially contact the road surface, the contact between the undersurface of the traction members surrounding the suction cavity walls and the tire pro-duces a vacuum within the suction cavities.  The vacuum causes the traction member to simultaneously grip the tire and the road surface until the traction member is lifted from the road surface, at which time the suction within the suction cavities is broken by the admission of air through the apertures be-tween the suction cavities and the outer surface of the trac-tion members.

Abstract: ABSTRACT OF THE DISCLOSURE      A plastic blow-molded container is disclosed having at least one and preferably a plurality of penetrable wall portions or sites which are sufficiently thin to permit piercing by a needle, spike or the like without coring or fragmenting, and also having a thicker recessed wall portion adjacent to each penetrable wall portion.  Each penetrable wall portion is formed during the blow-molding process by expanding the plastic parison over a projection in the mold cavity and into an adjacent recess in the cavity.  The thin penetrable portion of the container is formed within the mold recess and the thicker recessed portion of the container is formed by the mold projection.  With a plurality of penetrable sites, liquid may be withdrawn or added through a needle or spike inserted through one site, while dis-placement air is vented through a needle or the like inserted through another site.  The sites may be spaced sufficiently close together to permit sterilization, for example by swab-bing, in one motion.

Abstract: HIGH TURBULENCE SCREEN Abstract of the Disclosure Apparatus for screening a suspension of liquid, paper making fibers and undesirable rejects to remove a substantial portion of the rejects therefrom comprise a cylindrical screening member provided with circumferentially extending screening slots in the range of from greater than 0.008 inch to approximately 0.030 inch in width, and bars projecting from the inlet face of the screen and cooperating with rotating foils for creating a field of high intensity, fine scale turbulence adjacent the inlet face of the screen.  The paper making fibers and other particles of elongated thin shapes can pass through the screening slots, but relatively chunky reject particles, which would pass through the larger openings of conventional paper making screens, are rejected without fractionation of the paper making stock or appreciable variation in the consistencies of the feed, accepts and reject flows.  The apparatus has special utility in a two-stage screening system when installed immediately ahead of the headbox of a paper machine, and also as the primary screen in a waste paper stock preparation system.
