Abstract: The closure device includes: a retention ring seated around the container and axially locked between a finishing cord and a peripheral rib, which are externally incorporated to an upper region of the tubular body of the container; and a locking ring which is seated and affixed around an end cord of the lid and incorporating an outer skirt surrounding the end cord and the finishing cord and being elastically deformable, from a locked position against upward displacement at the locking ring, to a position unlocked from the latter. The device may further include a suspension handle coupled to the retention ring, and a seal means cooperating with both the retention ring and the locking ring to make evident a first opening of the container.

Abstract: A yoke type quick opening closure is provided. A torque bolt shares loads of the yoke with a drawbolt, and a separate safety bolt is provided. A common wrench interface feature is also provided.

Abstract: A drum band assembly for securing a lid to a drum. The drum band assembly includes a band having a first free end and a second free end, means for removably attaching the band to the drum and means for attaching the lid to the band. The band and the means for removably attaching the band to the drum are structured and arranged to provide for the drum band assembly to fit a drum having varying diameters or a drum of varying volumes, e.g. 55 gallon or 30 gallon drums.

Abstract: A mold includes at least one axial member carrying at least one sidewall molding surface for molding a sidewall of a tire, radial segments each carrying at least one surface for molding a tread of the tire and locking surfaces for connecting the axial member with the radial segments. First radial and axial locking surfaces which are displaceable and carried by the axial member cooperate with second radial and axial locking surfaces. The sidewall molding surface is integral with a fixed portion of the axial member. The first radial and axial locking surfaces are integral with at least one locking member mounted in the axial member and are movable relative to the fixed portion.

Abstract: An extendable trim ring for deadbolt locks having a collar slidably mounted in an annular flange. The flange is defined by a tubular wall outwardly-encircled by a protruding lip, and a notch running around the lip. In addition, the rim of the flange is defined by alternately longer and shorter teeth. The annular collar is slidably received within the annular flange. Specifically, the annular collar has a tubular wall seated within the notch of the flange. The inner surface of the collar is defined by a plurality of recessed axial tracks for slidably receiving the alternately longer and shorter teeth of the flange. Thus, the collar can be pulled from the flange (to extract said teeth from the tracks), rotated, and reinserted for pull-and-twist adjustment of the extension of the collar from the flange.

Abstract: A battery cover assembly (100) includes a battery cover (30), a resilient member (20), and a locking member (40). The battery cover has a latching member configured for engaging with the fastener mechanism of a housing (10), and an insertion hole (322) configured for the insertion of a latching post (120) of the housing. The resilient member is mounted on the battery cover, and has a first latching end (202) and a second latching end (204). The first latching end is secured on the battery cover. The locking member is rotatably attached on the battery cover and configured for resisting the latching post when the battery cover is in the closed position thereby preventing movement of the battery cover toward the opened position. The second latching end of the resilient member is fixed on the locking member.

Abstract: A gate latch having a ring suspended in a frame cooperating with a bar mounted on a gate or the like, wherein the gate is automatically latched upon closure by preventing the ring from moving upon engagement of the latch bar, is easily unlatched by raising the ring manually, and wherein the latch can be secured in the locked or unlocked position.

Abstract: Essentially "U" shaped endless elastic loops, with the opening facing inwardly, removably hold first foil covers over access openings of flanged containers. The foil is placed over the container opening and flange formed around the opening. The elastic loop is stretched to encompass the foil cover and flange and then released to secure the foil cover over the access opening. Clamping strips can be provided with the elastic loops to hold second foil covers onto the elastic loops and over the container openings. The clamping strips are provided with protrusions or recesses that match recesses or protrusions on the upper surfaces of the elastic loop to clamp foils between them and over the access openings.

Abstract: This relates to a tamper-evident closure cap having a tamper-evident structure for locking engagement beneath a transfer bead of a container neck finish. The closure cap includes a customary tamper-evident band which is of a diameter to freely pass over both external threads and a transfer bead of a container neck finish. In order that a bridge rupturing pressure may be applied to the tamper-evident band, there is provided a separate lock ring of a size to engage beneath the transfer bead while having an outer portion overlying the tamper-evident band to transfer pressure thereto during the removal of the closure cap. The lock ring is radially expansible to freely pass down over the threads and transfer beads during the application of the closure cap.

Abstract: In accordance with illustrative embodiments of the present invention, a gate latch apparatus includes a frame having spaced side members, a ring pivotally mounted between the side members, and means to limit outward swinging of the ring. A support rigidly secured with respect to the frame has a horizontal portion and an inclined portion to aid the user in positioning a latch bar on the horizontal portion where operation of the latch is assured. The bar causes the ring to swing inwardly during closure, and the ring drops downward upon passage of the bar to latch the gate closed. To release the latch, the ring is lifted to enable the bar to be removed from the support.

Abstract: A locking prevention apparatus for attachment to the locking shaft of a passage lock door knob assembly for an interior door consists of a split ring of substantially rigid material which engages circumferentially the external surface of the locking shaft between the interior door knob and the interior face plate of said door knob assembly to limit translational motion of the interior door knob along the locking shaft toward the interior face plate.

Abstract: A novel wafer retainer assembly is described which includes a ring member for securing wafers in a planetary fixture. The ring member is easily removed or inserted by means of thumb and forefinger pressure exerted on tabs extending from open ends of a resilient spring and maintains the wafers in apertures on the planet member without exerting any pressure on the wafers, thus avoiding breakage.

Abstract: A safety gate latch system having a gate tongue, first and second rings on opposite sides of the gate tongue and held in a frame in a manner such that when the rings are down, the gate tongue cannot move past either ring, a post-tongue, a second ring frame attached to the gate tongue and supporting primary and secondary safety rings disposed on opposite sides of the post-tongue whereby a gate using said system cannot be opened in a direction without the lifting of one of the first and second rings and also one of the safety rings.

Abstract: A device for the metallic sealing of an intermediate partition on the smooth inner wall of a cylindrical vessel, particularly with large diameters, by means of a sealing ring which is variable with respect to its diameter, on which sealing ring, the intermediate partition is fastened. The sealing ring is divided into at least two parts, and is able to be expanded at the separation positions, respectively, by one wedge each.
