Abstract: A self-uprighting delineator post construction comprises a base that may take a number of different forms and which is capable of being fixed to any suitable stationary object. A delineator post is provided which is of light weight impact resistance construction and may be composed of any one of a number of suitable impact resistant materials. A load cell is interposed between the base and delineator post and incorporates upper and lower load cell which are in abutment and pivotally disposed. The load cell elements are secured by a pair of cables disposed in side-by-side relation and maintained under tensile stress by open or a pair of compression springs which are subjected to a predetermined spring preload. The side-by-side cables fit within aligned passages of the upper and lower load cells which are of elongated cross-sectional configuration and serve to insure return of the delineator post to its properly oriented upright position after being forced toward the horizontal by an impact force.

Abstract: In a valve having a valve body and a bonnet mounted on the valve body, a bonnet lock secures the bonnet against relative rotation with the valve body. The bonnet lock cooperates with a pin driven into the valve body to lock the bonnet against rotation. Unequally spaced slots formed about the lower end of the bonnet lock permit adjustment of the bonnet lock for alignment with the lock pin. A jam nut threadably mounted on the bonnet engages the bonnet lock and maintains it in position.

Abstract: A universal shipping container comprises two separable and telescoping components. The shipping container includes a base plate supporting an upstanding tubular body to be received within a tubular body extending downwardly from a top ring plate. The ring plate includes a central opening for receiving the shanks of a drill bit therethrough. The telescoping components include cooperating fasteners for securely holding the drill bit within the shipping container.

Abstract: A water shutoff valve is disclosed in the preferred embodiment comprising a cylindrical body having a valve disk and water flow sensor therein. The sensor is operatively connected to a timer which automatically resets to zero upon interruption of water flow through the valve. The valve automatically closes upon continuous flow of water through the valve for a predetermined period of time, indicating a potential leak in the water supply line. The timer may be set for selected time intervals permitting the valve to remain open for short or long intervals as required.
