Abstract: The system uses an intermediary process in an object oriented computer environment to allow application objects to perform operations such as creation, deletion and accessing of other objects. Typically the other objects are database objects. The intermediary process allows associations to be made between add-on attributes and primary objects. The primary objects are objects that are designed to be used by an original application. A later application that wishes to use the same objects as the original application, but with additional attributes, can create, delete and access the additional attributes at run time so that extra functionality is provided to a user of the original application program in an efficient manner.

Abstract: An automatic signaling system from a tractor-trailer being accidentally lifted with the cargo by the overhead traveling crane includes a height-change sensor for triggering a pulse generator which drives a strobe light that is seen by a discriminator mounted above on the crane. The discriminator is coupled into the hoisting circuitry only and does not affect the "lowering" circuitry; it will interrupt hoisting only if the discriminator sees strobe flashes of a particular predetermined frequency and pulse duration.

Abstract: A grapevine trellis system incorporating substantially Z-shaped wire supporting bracket arms arranged and constructed to be alternately and universally mounted on solid T-bar posts, metal roll formed T-shaped posts, and/or conventional rectangular wooden posts.

Abstract: An improved and simplified transparent hand-held random selector device used for selecting numbers, letters or symbols, or a combination of the three which are used for playing lottery related games or other games. Such device comprised of a container (10) formed by a ball mixing receptacle (11) a ball receiving receptacle (12) and a two position sliding gate (15) containing within a plurality of marked balls (19).

Abstract: A sponge body of between 6"-12" long and square in transverse cross-section defining four 2" to 3" wide side surfaces is provided with an elongate handle, the inner end of which terminates approximately 1" to 2" short of the outer squared end of the sponge body which is formed with two perpendicular transverse notches providing a physical and visual guide for the sponge end to conform with moldings and to compressibly fit into tight spaces. The outer end of the handle terminates in a flared scraper blade. In a modified embodiment, the sponge end of the handle is formed with a brush element having bristles extending laterally beyond the plane of one side surface of the sponge.

Abstract: The invention provides an improved SWATH type vessel having pontoons and a stern plane located in a position to influence water flow in the region of the tail cone portions of the pontoons and the propellers to reduce depression of the water adjacent the propellers which would otherwise cause propeller ventilation when the vessel is moving at speed.

Abstract: An earring for pierced ears including a post that is slidably mounted in a vertical slot on the main body or frame of the earring so that the main frame, and the ornamentation carried thereon can be adjusted upwardly or downwardly in reference to the ear lobe and the post projecting therethrough.

Abstract: A stand up hand-held tool to penetrate soil for purposes of cultivation, weeding and the like. The tool comprises an elongate spear shaft, at least one end of which is pointed or otherwise formed to provide a leading edge for expeditious soil penetration. An elongate tubular handle grip, preferably extending about 2/5 the length of the shaft, is mounted on the shaft rod to provide a smooth manual hand grip surface to permit a user's hand to slidably grip the tool in a large variety of longitudinal positions along the lengthwise axis of the rod. The tool is specifically designed to permit a user in a standing position to manipulate the tool using an underhanded sliding grip with one hand on the smooth handle grip.

Abstract: An earring construction for pierced ears includes a main body or frame for supporting a post to project through the pierced ear lobe. Vertically spaced receptors, each capable of receiving and retaining the post, are provided or formed in the back side of the frame whereby in fitting an earring to an individual user, with the earring display side or ornament at least partially overlying the ear lobe, the post may be moved relatively upwardly or downwardly in order to have the earring hang at the optimum position and desired angle in reference to the vertical plane of the ear lobe.

Abstract: A sun visor is disclosed having a plurality of louvers of differing vertical heights with the innermost louver being the highest in elevation to thereby provide overhead light cutoff angles that shield the wearer's eyes from direct rays of the sun.
