There is at least one canal in the benching portion for connecting at least two of the passages in communication with each other, the canal having an open top portion.
Abstract: An earthquake, fire and wind resistant pre-fabricated building panel comprises a plurality of frame members. The frame members are connected together to form a frame lying in a frame plane, the frame defining a perimeter of the panel, the perimeter bounding an interior portion of the panel. At least some of the frame members are biased inwardly, generally in the frame plane, towards the interior portion of the panel. A first solidified castable substance is cast in the interior portion of the frame, between the frame members. A three-dimensional structure such as a house is formed by connecting the panels together. The connections absorb and distribute seismic forces to the entire three-dimensional structure and the biased frame members act to absorb residual seismic forces reaching the individual panels. The castable substance and biased frame members permit the panel to withstand both positive and negative loading and render the panel fire resistant.

Abstract: An apparatus and method for center finding and physical proximity measurement, the apparatus including a reactance controlled signal source for producing a measurement signal having a measurement signal frequency dependent upon reactance and a probe tip connected to the signal source. The probe tip is operable to receive the measurement signal while presenting a measurement reactance to the signal source, the measurement reactance being due to coupling of the probe tip with a workpiece adjacent the probe tip and the measurement reactance varying in accordance with the physical proximity of the probe tip to the workpiece. The measurement reactance causes the signal source to vary the measurement signal frequency according to the proximity of the probe tip to the workpiece. The measurement signal frequency is sufficiently high to enable the measurement signal to be radiated by the probe tip for reception by a remote receiver.
