Abstract: In accordance with one embodiment of the present disclosure, a method for filling a void of an electromechanical system includes forming a void within a support layer. A conductive layer is formed outwardly from the support layer such that a portion of the conductive layer partially fills the void. A remainder of the void is filled with an inorganic material. A mirror is formed outwardly from the inorganic material and the conductive layer.

Abstract: A novel outdoor sign apparatus for mounting to a ground surface, e.g. a real estate sign. The outdoor sign apparatus comprises a pair of horizontally spaced footings for a support base, a movable support frame that holds the sign, a plurality of stakes for mounting, and support elements. The support frame is supported by each of the footings and has a first position substantially perpendicular to the footings for display and a second position substantially parallel to the footings for transport. Support elements such as chains (or other similar means such as cables, rigid bars, etc.) connect between the support frame and the footings to selectively hold the support frame vertically upright in the first position. The support elements can be disconnected to release and lower the support frame to the lowered position for transport. The stakes are driven downward into the ground at an outwardly extending angle relative to the vertically upright support frame and sign.

Abstract: A planter includes a pair of toothed wheels which sweep mulch away from the path followed by furrow opening discs. The sweeper wheels are carried on the trailing end of a parallel bar linkage attached to a tool bar by which the planter is pulled. As a result of the parallel bar linkage, the sweeper wheels may float upwardly and downwardly independently of the planter frame in order to conform to uneven ground. A spring acts on the parallel bar linkage and may be adjusted either to press the wheels downwardly into the ground if the mulch is hard and dense or to urge the wheels upwardly and relieve some of the weight of the wheels from the ground if the mulch is loose and the underlying soil is relatively fine.

Abstract: A planter includes a pair of toothed wheels which sweep mulch away from the path followed by furrow opening discs. The sweeper wheels are carried on the trailing end of a parallel bar linkage attached to a tool bar by which the planter is pulled. As a result of the parallel bar linkage, the sweeper wheels may float upwardly and downwardly independently of the planter frame in order to conform to uneven ground and achieve more effective removal of the mulch without significantly disturbing the soil. The forward location of the sweeper wheels enables a coulter to be mounted on the planter frame and slice vertically into the ground ahead of the furrow opening discs.

Abstract: A tank carrier for carrying agricultural liquid for application to fields has a tank frame is pivotally suspended below a castor wheel frame at one end thereof and is hitched to a tractor or other pulling device at the other end thereof.
