Abstract: Apparatus and methods are described for marking stakes and carriers. Marking stakes have a body and tab. The body's proximal end and the tab can be tilted out of a plane containing the remainder of the body so that apertures on the body and the tab register with one another and the body is tensioned substantially upright. The body's length is sufficient so that when the proximal end is fastened to a mounting surface the distal end is visible. The body may be flexible, avoiding dislodged, broken, bent, or moved stakes and preserving lines, curves, grades, offsets, cuts, and fills. The stake can remain flat when not in use, overcoming the problem of handling and transporting bulky stakes. Marking stake carriers carry lengthy stakes and fasteners and fasten to surveying rods with various diameters, providing a simple and organized method to handle and transport marking equipment.

Abstract: A tilting mechanism incorporated into a conventional wheelbarrow, the wheelbarrow including a bucket portion, a pair of elongated handles supporting the bucket portion, and a front wheel. The tilting mechanism includes a frame adapted to being secured to a rearwardly extending location of the elongated handles and such that the bucket portion is disposed between the frame and the front wheel. A pair of elongated supports are incorporated into the frame and, in combination with the front wheel, support the wheelbarrow upon a surface. The frame includes structure for establishing an angle or incline, relative to an uneven or peaked surface, and is actuated to facilitate tilting of the bucket portion about a longitudinal axis extending through the wheelbarrow.

Abstract: A detention filter system for the temporary accumulation and storage of storm water runoff is disclosed for limiting the rate of runoff from a developed tract of land to no more than that which was naturally discharged from the same tract when in its prior undeveloped state. The system includes one or more conventional rip rap filled gabion boxes which may be aligned end-to-end along the edge of a developed parcel of real estate so that storm water can run off into the boxes and temporarily accumulate therein. The system also includes a sheet of porous fabric or perforated sheet, attached to and covering a surface of the gabion boxes to restrict the rate of flow of storm water runoff flowing through the boxes and the sheet to a downstream storm drain, storm sewer or stream. The sheet may be formed of two or more layers of the porous fabric or perforated sheet.

Abstract: In each of the two disclosed switches, an electrically conductive contactor plate is mounted on an insulating carriage, slidable in a casing along a path which is parallel with first and second parallel contact bars, mounted on an insulating wall of the casing. The contactor plate has first and second contact points for slidably engaging the contact bars during a portion of the movement of the contactor plate. During the remainder of such movement, the contact points slidably engage insulating boss portions which project from the insulating wall and are flush with the contact bars. The contactor plate has a third contact point projecting therefrom and slidable along an insulating ridge projecting from the insulating wall and disposed between the contact bars. The insulating ridge is flush with the contact bars for slidably supporting the third contact point while keeping it from engaging the contact bars. The insulating ridge is also flush with and connects with the insulating boss portions.

Abstract: A flexible surveyor's marker constructed of an elongated strip of stiff, yet flexible, foldable material such as Mylar plastic including an elongated body portion creased along a longitudinal centerline thereof and a pair of tabs connected to a transverse fold line along one end of the body portion and containing a nail hole in each tab is disclosed. The tabs are slidable one across and over the other to a position wherein the nail holes register with one another. The body portion is tiltable out of a plane containing the tabs toward a direction perpendicular to the plane containing the tabs as the tabs are slid one across and over the other toward registry of the nail holes.
