Abstract: The present disclosure relates generally to building surface baffles, for example, suitable for forming a room divider, a wall covering, an acoustical surface, or a ceiling surface. The present disclosure relates more particularly to a baffle for a building surface. The baffle includes an elongate body extending along an axis from a first end to a second end. The elongate body has a depth including a narrow portion that extends away from the axis along a first direction and a wide portion. The wide portion includes first and second projections that extend laterally outward from the first direction. The baffle also includes a first aperture extending into the first end of the elongate body along the axis and a second aperture extending into the second end of the elongate body along the axis.

Abstract: The present disclosure relates generally to ceiling panel carriers, for example, suitable for forming a ceiling surface by supporting a plurality of ceiling panels. The present disclosure relates more particularly to a carrier configured to mount ceiling panels at varying heights. The carrier includes an elongate support structure extending in a longitudinal direction and a plurality of attachment projections positioned along the length of the carrier. Each of the attachment projections extends down from the support structure and is configured to hold a ceiling panel. The attachment projections include a first group with a body and an upper hanger that has a first upper flange extending from the body in the longitudinal direction. The attachment projections also include a second group with a body and a lower hanger that has a first lower flange extending from the body in the longitudinal direction.

Abstract: A percussion or hammer drill is provided including a drill plate arranged in the head end of a drill shaft, extending completely across the diameter of the drill shaft and comprising an open front face. Wedge-shaped cutting edges and flanks form two main cutters on the front face, whereby a plane running through the drill axis forms a mid-plane-of both main cutters. The main cutters form a tip angle in the range of approximately 140° to 180° and are separated by a central point.

Abstract: A method and apparatus for delivering a decoded first signal related to a current or predicted condition of a geographic area across a network serving the geographical area to user apparatus. The network includes a headend, at least one source for providing an undecoded first signal related to the current or predicted condition of the geographic area, at least one decoder and at least one encoder. The method comprises decoding the first signal, transmitting the decoded first signal across the network, receiving the decoded first signal and generating a second signal for transmitting across the network to user apparatus in the geographic area. The apparatus and methods permit the collection of information, bringing of the information to a common point, decoding of the information if necessary, and distribution of the information to the appropriate address(es) on the network to which data can be addressed, received, assembled and displayed or played back.
