摘要： Systems and methods for forming a channel in an uncured concrete slab are described. The system includes a first blade, a second blade, and a third blade. The first and second blades are oriented vertically relative to the concrete slab and spaced a predetermined distance apart. The third blade is positioned between the first blade and the second blade to form a concrete-receiving interior. The system also includes a conveyer having fin(s) extending therefrom to move material through a chute. The first, second, and third blades are configured to cut the channel in the concrete slab and direct excess concrete into the chute where the conveyer moves the excess concrete out of and away from the channel.

摘要： A honeycomb body having a cutout, an assembly including the honeycomb body, and a method of manufacturing. The method includes forming the honeycomb body having a matrix of intersecting walls that define a plurality of cells and channels extending longitudinally through the honeycomb body. A subset of the channels are plugged to create a plurality of plugged cells in a reinforcement region of the honeycomb body. Material is removed from the honeycomb body within the reinforcement region in accordance with a peripheral shape that passes through the plugged cells to form a cutout that extends an axial depth into the honeycomb body.

摘要： An airfoil for a gas turbine engine is provided that includes a first portion formed from a first plurality of plies of a ceramic matrix composite material and defining an inner surface of the airfoil, as well as a second portion formed from a second plurality of plies of a ceramic matrix composite material and defining an outer surface of the airfoil. The first portion and the second portion define a non-line of sight cooling aperture extending from the inner surface to the outer surface of the airfoil. In one embodiment, a surface angle that is less than 45° is defined between a second aperture and the outer surface. A method for forming an airfoil for a gas turbine engine also is provided.

摘要： Embodiments of a system and a method for manufacturing a gypsum board can be used to produce a gypsum board having at least one perforated cover sheet via a cover sheet perforator system. The cover sheet perforator system can include a perforator roller is disposed downstream of a forming station along a machine direction, a roller support frame for rotatably supporting the perforator roller such that its rotational axis extends along the cross-machine direction, and a motor arranged with the perforator roller to rotate the perforator roller about the rotational axis. The drive motor can be adapted to rotate the perforator roller with a tangential speed substantially equal to the line speed to produce a series of perforation holes in an upwardly-facing cover sheet as the gypsum board moves past the perforator roller.

摘要： Various embodiments for a median barrier finishing machine are described. A median barrier finishing machine may include a housing configured to encapsulate at least a portion of a median barrier, where the housing comprises a first vertical wall, a second vertical wall, and a horizontal wall. The median barrier finishing machine may include at least one adjustable member configured to couple the housing to the vehicle and retain the housing a predetermined distance relative to the vehicle while the vehicle is in motion. Further, the median barrier finishing machine may include at least one finishing device disposed within the housing, where the at least one finishing device is configured to contact a surface of a median barrier at least partially positioned within the housing and treat the surface as the vehicle moves the housing along a length of the median barrier.

摘要： A method for recycling concrete mass in a slipform casting process, where the concrete mass is first cast and compacted with a slipform casting machine comprising a restricted cross-section to form a concrete product to be cast and at least one concrete mass tank for feeding concrete mass to the restricted cross-section, and the cast concrete mass is removed from areas of the fresh cast portion of the concrete product, wherein the removed fresh concrete mass is conveyed and dosed back to the at least one concrete mass tank of the slipform casting machine. The invention also relates to a system and a casting machine for implementing the method.
