Abstract: A reusable factory fixture frame is disclosed for use in the manufacture of a color cathode ray tube having a flat faceplate and a tensed foil shadow mask. The frame provides for mounting an in-process shadow mask during photoexposure of an in-process faceplate in a lighthouse. The frame comprises generally rectangular frame means and quick-release mechanical mask-retaining means for temporarily and removably supporting an in-process shadow mask in tension. The frame has at least first six-point indexing means on a first side for registration with complementary registration-affording means on an exposure lighthouse, and second six-point indexing means on a second, opposed side for registration with complementary registration-affording means on an in-process faceplate. As a result, the in-process shadow mask can be precisely registered and re-registered with the lighthouse and the in-process faceplate for the photoexposure of the in-process faceplate while retaining the in-process shadow mask in tension.

A method and apparatus for manufacturing the aforesaid pouches are also described herein.

Abstract: An improved two element locking construction for releasably securing the side edges of a shower curtain to the outer surface of a shower enclosure to prevent leakage of water outwardly of the enclosure and reduce the inward motion of the curtain. The construction includes a first element which is secured to a surface of the enclosure using a suitable pressure sensitive adhesive, the first element forming a recess. A second element is secured to a surface of the shower curtain adjacent a vertical edge, and has a shaped longitudinally extending projection selectively engageable with said first element in an interstice leading to said recess. Disengagement of the elements is accomplished by manually flexing a resilient wall of the first element to temporarily enlarge the insterstice engaging the projection on the second element.

Abstract: A sheet gripping assembly for gripping either single ply or double ply thin pliable sheet material such as plastic film. The gripping assembly has a mating channel to be secured to a support with the sheet material spanning the open channel side, and a channel-shaped cap which snaps over the base channel to grip the sheet material between the channel and cap in such a way that edgewise tension in the sheet material tending to separate the cap from the base channel urges their sheet gripping edges into more firm sheet gripping relation, thereby to more firmly grip the sheet material. The primary application of the invention is securing plastic film to an open frame structure to form a greenhouse enclosure.

Abstract: Disclosed are bags especially adapted to be made from plastic material and in which the bag body film or material and extruded plastic zippers are fusibly incompatible. A pair of extruded plastic zipper strips having reclosable zipper profiles facing toward one another along the lower sides of pull flanges of the bag have the opposite ends of the strips sandwiching opposite side seal seams of the bag therebetween. The opposite side seal seams have holes therethrough, and fused connecting anchors formed from the material of the zipper strip ends extend through the holes. The bag may be closed by squeezing the zipper strips together so that the profiles interlock with one another and interlock the intervening area of the bag walls therebetween. A method of making the bags is also disclosed.

Abstract: An assembly including a clasp member having a pair of opposing upper and lower gripping jaws which receive selected portions of sheets therein; and a wedge member for insertion between the inner surface of said gripping jaws along with the bedsheets for locking the sheets between the clasp member and the wedge member. The preferred wedge has a triangular cross-section and being of a size somewhat smaller than the space between the opposed gripping jaws, to provide some clearance when the wedge is inserted between the gripping jaws. When tension is applied to the sheets the wedge member is caused to rotate and wedge the edges thereof against the inner surfaces of the gripping jaws to more tightly grip and retain the sheets in position.

Positioning and securement of the article of bedclothing in an expeditious manner is thus provided.

Abstract: A clip for retaining thin plastics film material (6) in tension formed of a pair of elongate channel members (2,4) removably assembled together in inverted relationship. The film material passes through the fixing between opposed cooperating complementary sinuous surfaces (8,3;9,12) of the flanks of the channel members and in so doing passes over surface portions of the fixing at the entrance to the cooperating surfaces of each flank pair, which are exposed to direct radiation. To avoid degradation of the plastics at these surface portions, means (30,32) are provided on one of the channel members to cover or shield these surface portions from such direct radiation. The covering or shielding (30,32) may be integrally formed with one of the channel members of removably afixed thereto.

Abstract: A mechanical fastening system for securing a flexible sheet within a channel member via an insert member wherein the latter is made of flexible resilient material having a central longitudinal flex notch that serves to define two adjacent wing portions and permits a temporary elastic deformation of the insert member into an inverted V-shape for insertion of the insert member, together with the flexible sheet, into the channel member. A method for securing the flexible sheet within the channel member, via the resilient insert member, is also presented.

Abstract: A frame strip for use in window frames or other arrangements for securing the edge of either a flexible sheet or a rigid sheet provides a strip member incorporating a cavity having two sides. One side is straight and the other side is generally parallel to the first side and incorporates a first portion and a second portion, the first portion being closer to the first side than the second portion and being interconnected by a curved section. The space between the first portion and the first side is sufficient to receive the narrow side of a rectangular locking member, the other side of which is shorter than the distance between the edge of the interconnecting portion and the bottom of the cavity and longer than the space between the second portion and the first side so that the locking member is prevented from rotation within the cavity to retain a flexible sheet wrapped therearound.

Abstract: A conduit restraining clip to snugly secure one or more axially aligned tubes, wires, lines, cords, hoses and the like, which may vary in bundle size, comprising a base with two side walls projecting generally vertically from its opposite edges and two pairs of spaced-apart arms projecting from the side walls into the interior of the clip and downwardly toward the base of the clip. The arms of the clip flex downwardly and laterally to enable the clip to receive conduits and the upper pair of arms and the lower pair of arms cooperate to cradle the clip's contents in suspended restraint. In one embodiment of the invention, the arms of the clip are equipped with overlapping projections which form an expandable central enclosure which is well suited for holding a plurality of small conduits. Clips according to the invention can be provided with affixing devices for securing the clip contents to another object.
