An induction heating tool has an induction heating coil configured to generate a magnetic field closely matched to the shape of the anchor plate. The induction heating tool includes a base configured to assist an operator in aligning the coil over each anchor plate. In the disclosed embodiments, the base supports a circular induction coil with a structure that clearly shows the position of the induction coil. In the disclosed embodiments, material surrounding the induction coil is removed or made transparent so the operator can see the roof immediately surrounding the induction coil as an additional aid in positioning the tool over anchor plates.

Stand-up induction heating tool for membrane roofing

A portable induction heating tool is provided as a membrane roofing tool for use in sealing anchor plates with a heat-activated adhesive to a membrane roofing member. The tool uses two different audible tones so two tools can be used simultaneously on a single roof, while allowing a user to easily distinguish between the operation of both tools. The main housing containing electronics is weather-tight, and requires no forced-cooling devices. The controller automatically performs data logging functions, such as counting the number of anchor plates per job or per day that have been properly placed, counting the number of activation events for a tool's life, tracking the number of faults which occur as the tool is being used, and the controller can identify the type of fault that occurs during operation of the tool. The controller also stores energy setting changes in memory.

Stand-up membrane roofing induction heating tool

A circuit fault detector and interrupter which consists of parallel current conduction paths, including a path through a mechanical contactor and a path through a power electronics switch having active feedback control. A fault can be detected by a fault detection circuit within 50 &#x3bc;S of the occurrence of the fault, causing the mechanical contactor to be opened and the fault current to be commutated via a laminated, low-inductance bus through the power electronics switch. The power electronics switch is thereafter turned off as soon as possible, interrupting the fault current and absorbing the inductive energy in the circuit. The fault current can be interrupted within 200 microseconds of the occurrence of the fault, and the device reduces or eliminates arcing when the mechanical contactor is opened.

A portable induction tool is provided for soldering or brazing sections of metal pipe together. A work coil head (with induction coil) is U-shaped, allowing placement of the head around lengths of pipe, heating a susceptor (e.g., the pipe) to form a joint, and then to be withdrawn after the pipe joint is made. In one form, the tool uses heat pipes to remove thermal energy from the head, and also a heat exchanger for higher-powered units. Power capacitors are generally included with the induction (work) coil to create a tank circuit of a resonant frequency. The induction coil uses Litz wire, copper tubing, or heat pipes with a conductive outer skin to carry the high-current being delivered to the induction coil. The induction coil has a general racetrack configuration, which is typically wound in a U-shape (or as a semicircle) as a single winding, with multiple turns.

Induction coil design for portable induction heating tool and method for its use

An improved induction heating apparatus is provided for attaching membrane roofs. A top membrane layer is attached to attachment disks that hold sheets of thermal insulation to the top of roof substrates. The heating apparatus emits a magnetic field that raises the temperature of the disks and a heat-activated adhesive on top of the disks which, after cooling, becomes adhered to the bottom surface of the top membrane layer. The disks in turn are attached via fasteners to the substrate portion of the roof structure. The apparatus includes a set of bottom guides that allow a user to find the attachment disks mechanically, without actually seeing those disks beneath the top membrane layer. A fine locator circuit is provided, using a magnetic field, and the apparatus allows a user to stand upright while operating the apparatus.

This invention relates to a transformer and more particularly, to a system and method for making a transformer utilizing dynamic magnetic compaction. A coil is placed in a conductive container, and a conductive powder material, such as ferrite, is placed in the container and surrounds the coil and the turns of the coil. A power supply energizes a capacitor which subsequently provides a high energizing current to a second, energizing coil within which the container, material and inner coil are situated, thereby causing the container, powder materials and coil to be compacted to provide an electrical component, such as a transformer, motor, commutator, rotor or choke.
