Systems and methods for a concrete apparatus with incorporated lifter are provided. A concrete apparatus is formed by placing a reinforcement system in a mold. The reinforcement system comprises a lifter. Concrete is poured into the mold such that the lifter protrudes from the poured concrete. After the concrete has hardened and the mold is removed, the lifter is used to carry and position the concrete apparatus. After the concrete apparatus is positioned, the lifter is removed at the circumference of the concrete apparatus leaving no holes, thereby eliminating water leakage due to lifting methods.

In embodiments of the present invention improved capabilities are described for reproducing the size of a first ceramic ware in the making of a second ceramic ware. In embodiments, the first ceramic ware may be received on a pottery wheel. A hinged pointer may then be presented to a position on the first ceramic ware, where the hinged pointer may include a pointer connected to a supporting structure by way of a hinge. The first ceramic ware may then be removed from the pottery wheel, and material for the making of the second ceramic ware may be placed on the pottery wheel. The process of making the second ceramic ware may then progress, where the making includes sizing the second ceramic ware to the position of the hinged pointer.

Self-repairing, fiber reinforced matrix materials include a matrix material including inorganic as well as organic matrices. Disposed within the matrix are hollow fibers having a selectively releasable modifying agent contained therein. The hollow fibers may be inorganic or organic and of any desired length, wall thickness or cross-sectional configuration. The modifying agent is selected from materials capable of beneficially modifying the matrix fiber composite after curing. The modifying agents are selectively released into the surrounding matrix in use in response to a predetermined stimulus be it internal or externally applied. The hollow fibers may be closed off or even coated to provide a way to keep the modifying agent in the fibers until the appropriate time for selective release occurs. Self-repair, smart fiber matrix composite materials capable of repairing microcracks, releasing corrosion inhibitors or permeability modifiers are described as preferred embodiments in concrete and polymer based shaped articles.

The aim of the invention is to produce concrete moulded blocks, using a mould which is subjected to a vibrating process. Said mould comprises a frame (FR) and a moulding insert (FE) which is maintained therein. A device comprising receiving elements arranged in said moulding insert (FE) for receiving a displacement sensor (SE) is provided, in addition to an arrangement comprising said device and at least one sensor. The invention discloses advantageous embodiments and arrangements of said receiving elements. The arrangement of the sensor (SE) on the moulding insert (FE) is particularly advantageous and provides an additional displacement variable for relative displacement between the moulding insert and the frame by combining the displacement variables of a sensor (SE) on the moulding insert (FE) and a sensor (SE) on the frame (FR).
摘要:
A mold assembly for manufacturing concrete blocks that is adapted for use in a concrete block machine. The mold assembly includes a plurality of liner plates, each having a major surface, the liner plates configured such that the major surfaces form a mold cavity having a desired form, and wherein at least one of the liner plates is moveable. A gear drive assembly is selectively coupled to the at least one moveable liner plate and configured to move the at least one moveable liner plate toward and away from an interior of the mold cavity. A stabilizer assembly is operatively coupled to the gear drive assembly and is configured to support the gear drive assembly as it moves the at least one moveable liner plate.

A method and system for manufacturing a mask for plugging cells in a honeycomb substrate includes capturing an image of the substrate's end through an end-adhered transparent or translucent film using a camera, forming openings using a laser, wherein a working distance, WDC, of the camera while capturing the image is substantially the same as a working distance, WDL, of the laser while forming the openings. Also disclosed is an apparatus for manufacturing a mask on a honeycomb substrate, having a laser to form openings in a film applied to the substrate's end; and an optical system, wherein either the optical system or the substrate is moveable between first and second operating positions. In a first embodiment, the camera moves whereas in the second, the substrate moves. In each embodiment, the image is obtained without obstructing the path of the laser. Also disclosed is a system for manufacturing masks including multiple cameras and lasers wherein masks are formed on both ends of the substrate without having to reposition the substrate in a holder.
