A magnetic clamping heat sink assembly is disclosed including a magnetic assembly with a carrier body including a magnet. A spring resiliently biases the carrier body. A base assembly includes a base plate. In a first operating condition, the base assembly of the magnetic clamping heat sink assembly is positioned in a first position away from a ferromagnetic element, and the spring holds the carrier body at a medial position spaced apart from the base plate. In a second operating condition, the base assembly of the magnetic clamping heat sink assembly is positioned in a second position adjacent to the ferromagnetic element, and the carrier body is driven downward against a force of the spring to a lower position and into contact with the base plate by magnetic attraction between the at least one magnet and the ferromagnetic element.

A method for sealing a substrate having one or a number of electrically conductive surface regions, including the (i) arranging of a sealing membrane, having a plastic layer and an outer adhesive layer made of a melt adhesive, on the substrate, wherein the adhesive layer is facing towards the substrate, (ii) the positioning of an induction heating device over the sealing membrane, and (iii) heating the melt adhesive for the fusion or partial melting thereof by means of the inductive heating of the electrically conductive surface regions with the induction heating device, in order to adhere the sealing membrane to the substrate after cooling. The method facilitates the sealing of substrates with sealing membranes. Same is suitable, in particular, for sealing floors or ceilings or parts thereof.

A roofing system having at least one underlayment layer; at least two nail fasteners attached to the at least one underlayment layer and into the roof deck, wherein the head of each of the nail fasteners is above the at underlayment layer and the shaft is driven through the underlayment layer and into the roof deck; at least one bead of adhesive applied above the underlayment layer; and at least one metal roofing panels placed on the at least one bead of adhesive applied above the underlayment layer, wherein the at least one metal roofing panels are above the at least two nail fasteners and the at least two nail fasteners do not penetrate the at least one metal roofing panels.

A device for heating and connecting sheets (11, 12, 111, 121) of bituminous or synthetic membranes (100), comprising at least one sheet (11, 12, 111, 121) of a bituminous or synthetic membrane (100) which is applied to at least one base layer (141), said membrane (100) being formed with a single compound or having at least one bottom layer including a compound or a bituminous mixture and at least one upper layer including a polymeric material and an electrically conductive material, which is heated; in particular, a body (13, 23) having a mainly longitudinal (A) development and placed on a first edge (11a, 21a) of a first sheet (11, 21, 111, 121) of the membrane (100) in order to connect said first edge to a second edge (12a, 22a) of a second sheet (12, 22, 111, 121) of the membrane (100) is provided with an upper face (13a, 23a).

An induction heating tool that holds voltage or current supplied to the induction tank circuit constant and tracks changes in the other of voltage or current during each induction heating cycle. The disclosed induction heating tool exploits the fact that the resistance an attachment plate increases along with the temperature of the attachment plate. During an induction heating cycle, the attachment plate is magnetically coupled to a work coil and the resistance of the attachment plate is reflected to the circuit. Changes in the resistance of the attachment plate alter the pattern of energy delivery from the work coil to the attachment plate in a predictable way. Calculations accurately predict the temperature of the attachment plate over a wide variety of ambient conditions, including the presence of moisture at the membrane/attachment plate interface. The disclosed induction heating tool produces consistent results without calibration for ambient conditions.

A method comprises selecting a mounting bracket having opposite horizontal, parallel wings, and a raised portion between the wings, applying a coating of an uncured first sealant material to a first area of a roof surface above decking of the roof, the first area having an outer perimeter greater than overall area of the bracket, urging undersurfaces of wings of the bracket into the uncured sealant material, securing the mounting bracket to the roof by screws applied into the roof decking through holes provided in the wings of the bracket, and applying a second sealant material over heads of the screws on upper surfaces of the wings of the bracket.

A modular anchor has a metal plate having a pattern of holes around a periphery, the forming a boundary of a central inner area, a metal bracket having a raised central portion and parallel wings having upper and lower surfaces in parallel horizontal planes, with the bracket joined to the metal plate at a central location within the hole pattern, the wings and the metal plate coated with a material to facilitate heat welding to membrane; and a transition membrane positioned on the metal plate with the raised portion of the bracket extending upward through an opening in the transition membrane, and with the transition membrane heat welded to the upper surfaces of the wings of the bracket and to the metal plate everywhere within the central inner area, leaving the pattern of holes exposed.

A machine for welding an overlapped region of two adjacent strips of material and a method of using the same. The machine includes a housing with front and rear ends, a wheel train engaged with the housing for moving the housing across the material; a nozzle on the housing having a welding head at a free end; the nozzle being positionable at least partially beneath the housing's bottom wall for welding the overlapped region; front and rear pressure rollers engaged with the housing, where the front roller is positioned forwardly of the welding head and the rear roller is positioned rearwardly of the welding head; wherein the rear pressure roller applies pressure to the overlapped region when the wheel train moves the housing in a forward direction; and the front pressure roller applies pressure to the overlapped region when the wheel train moves the housing in a reverse direction.

A roof assembly comprising: a roof deck; a thermoplastic membrane covering the deck; and a fabric having disposed thereon expandable graphite.
