Abstract: An upwardly open end portion of a plastic container straight sidewall is telescoped by an inverted U-shaped portion of a plastic engagement ring with a generally transverse, outward flange on the container sidewall snap interengaging with a similar engagement ring flange. An engagement ring U-shaped portion extends transversely inwardly having, in certain embodiments, either a simple or complex outer wall common with the inverted U-shaped portion and in all cases an interior wall spaced inwardly therefrom. An edge portion of a plastic cover overlies the engagement ring U-shaped portion and has a downward extension fitting therein divided into an exterior wall outwardly abutting the ring U-shaped portion outer or common wall and a transverse inward flange snap interengaging with a similar flange on the ring interior wall.

Abstract: An electrically illuminated sign has a box-like frame with a front face opening and encloses a message plate displaying a message unit through the opening. A separate opaque border strip circumscribes the message unit of the message plate forwardly overlying the same and being forwardly engaged by a frame flange. Opposite side parts of the border strip have directional signal openings formed therethrough normally exposing a contrasting coloration of the message plate therethrough and selectively slidably removable cover strips are positioned between the message plate and border strip covering the border strip directional signal openings with a coloration matching the border strip. The sign may be attached to a mounting surface by a two-piece mounting bracket having a first part secured to the frame and a second part securable to the mounting surface with the bracket parts having slidably interfitting dove-tail portions securing the parts.

Abstract: A machine or apparatus simultaneously manufactures a core-reinforced welded panel and assembles core strips in operative relationship with the face sheets of said panel. The machine includes a first welding head which is insertable in the space between the face sheets and has welding electrode means thereupon which internally weld securement portions of the core strips to adjacent inner surfaces of face sheets of any desired thickness.The welding head includes movable jaws mounting the welding electrodes to move the welding electrodes into engagement with the securement portions of the core strips and the welding electrodes are resilient to permit them to move independently of the movable jaws and each electrode provides an electrically isolated weld.A second welding head is provided which is capable of securing web portions of the core strips by weldments to one another after the weldment of the core strips at their securement portions has been accomplished by the first welding head.

Abstract: A horizontal water inlet tube is inwardly connected reversely through a valve within a horizontal valve housing and from the valve housing downwardly into a generally vertical water outlet tube. The valve is controlled by a valve control arm projecting generally horizontally from the valve housing downwardly connected through a float connector to a float vertically slideable on a float guide extending downwardly from the valve housing. A diverter at the upper end of the water outlet tube receives water flow generally horizontally from the valve housing into a pair of spaced, downward helical grooves directing the flow spirally into a pair of spaced vertical grooves for ultimate discharge downwardly through the water outlet tube. The diverter vertical grooves are larger in cross-section than the respective helical grooves and are formed by radial plates converging centrally to a cylinder at groove upper portions and an inverted cone at groove lower portions, each vertical groove occupying in the order of 120.

Abstract: A door latch construction has exterior and interior operators connected through a latch driving mechanism operable for extending a bolt from a door edge. The exterior operator includes a lock cylinder telescoped by a thickened, hardened metal guard collar with the guard collar longitudinally inwardly abutting a metal shield retaining the shield inwardly against an exterior face of the door. The shield also extends inwardly of the door interior at least partially annularly around a portion of the latch driving mechanism thereby deterring manipulation of the latch driving mechanism by penetration through the door exterior face. The lock cylinder longitudinally inwardly abuts the guard collar so that the guard collar retained between its lock cylinder abutment and its shield abutment is rotatable to deter exterior attack against the overall exterior operator.

Abstract: A grease gun is fed from a constant supply under pressure. The gun has a hand-pumped lever for delivering shots of grease either at high pressure and low volume or low pressure and high volume depending on a changeover valve. Air bleeds from the gun through the nozzle by a single pump of the lever. The lever causes a pushrod to open a one way valve allowing grease to travel entirely through the gun to the nozzle.In another version the pushrod is replaced by a cone valve. Both versions are for single handed operation.

Abstract: A rigid plastic elbow has a fluid passage formed therethrough from a relatively straight refill hose connecting portion and through a reduced length relatively straight overflow tube discharge portion. The refill hose connecting portion is connectable to an end of a flexible refill hose directing water from a water level control valve in a toilet flush tank. A flexible metal clip secured to the overflow tube discharge portion mounts the mounting member on the upper end of a vertical overflow tube of the toilet flush tank with the overflow tube discharge portion directing water from the refill hose downwardly into the overflow tube upper end.

Abstract: An identification device employing a myriad of modes of identifying indicia placement, wherein the device comprises a flexible band having opposed first and second ends wherein the bands may be in severable sheet form and wherein once severed the band is of sufficient length for encircling, captive relationship about an object or person to be identified. A multitude of various means of securing the first and second ends together is available. Additionally, the availability of a choice of identification means, some of self-imprinting character, provides an identification device which is highly versatile having a plurality of end uses.

Abstract: A hand held vegetable slicer has a two part molding which defines a window spanned by an array of blades; both parts have teeth enabling them to interfit to form a comb joint and the ends of the blades are imprisoned between adjacent teeth. In one version the two part molding is a sub-assembly which fits into a window in a preformed handle. In another version the handle has both window and teeth on two opposite edges of the window and a separate toothed molding is used to imprison the blades. ABS plastic and alloy are provided.

Abstract: The invention provides a siphonic apparatus to effect irrigation of a field from a water supply. The apparatus comprises a bridging structure which includes a chassis fabricated from spaced longitudinal bottom members, spaced longitudinal top members interconnected by cross members, vertical struts, diagonal braces and side plates to form a rigid structure having a central elevated section and downwardly angled end sections, the ends of which being on substantially the same plane as the surface supporting the chassis.At least one siphonic tube is rotatably, transversely supported in the chassis.
