Abstract: The subject of the invention is a process for melting and refining vitrifiable materials, such that all or part of the thermal energy necessary for melting the said vitrifiable materials is supplied by the combustion of fossil fuel(s) with at least one oxidizer gas, the said fuel(s)/gas or the gaseous products resulting from the combustion being injected below the level of the mass of vitrifiable materials (7). The refining of the vitrifiable materials after melting takes place at least partly in the form of a “thin layer”. The invention also relates to the device for implementing the process and to its applications.

Abstract: The invention relates to methods and apparatus for fabricating a three-dimensional object from a representation of the object stored in memory. The apparatus includes a stationary build table for receiving successive layers of a build material and at least one movable printhead disposed above the build table. The printhead deposits a binding material in a predetermined pattern on each successive layer of the build material to form the three-dimensional object.

Abstract: A roof vent ingress prevention device includes a generally tubular base having a circumferential side wall, a lower pipe-engaging section and an upper section having at least two side vents formed therein, the side vents extending through the side wall for venting of gas from within the generally tubular base. A base slippage prevention device such as a circumferential bead or outward slant to the wall means is mounted on an outer face of the circumferential side wall intermediate the lower pipe-engaging section and the upper section of the generally tubular base and is operative to prevent the generally tubular base from slipping downwards into a roof vent on which it is mounted. Finally, a vent cap is mounted on the upper section of the generally tubular base, the vent cap including a plurality of vent openings formed therein for venting of gas from within the generally tubular base.

Abstract: An apparatus, system and method including a latching device for displaceably retaining a panel relative to a frame. The latching device includes at least a bolt which is carried on the latching device and is operatively associated with the panel to prevent disengagement of the panel. The latching device includes at least one pressure responsive device operatively coupled to the bolt to retain the bolt in a desired position and release the bolt when a predetermined pressure differential occurs relative to two, generally opposite, sides of the panel or when a pressure decrease occurs on one side of the panel.

Abstract: The invention relates to apparatus and methods for producing three-dimensional objects and auxiliary systems used in conjunction with the aforementioned apparatus and methods. The apparatus and methods involve continuously printing radially about a circular and/or rotating build table using multiple printheads. The apparatus and methods also include optionally using multiple build tables. The auxiliary systems relate to build material supply printhead cleaning diagnostics, and monitoring operation of the apparatus.

Abstract: A device to assist in the opening of a manhole cover has a biasing member such as a spring and a pivot rod or rods. The rods and spring are each pivotably attached to first and second mounting brackets. The first mounting bracket is attached to a skirt for seating the manhole cover and the second mounting bracket is attached to the underside of the cover. The spring acts to rotate the manhole cover in a reverse direction to which the cover is intended to be opened until the cover contacts the rod or rods. Then, the cover is rotated in an opposite direction, preferably with manual assistance, using the rods as pivot arms.
