Abstract: A carpet seaming iron has two heating elements to maintain the iron at desired temperature with a minimum of temperature oscillation. One element remains energized as long as the iron is switched on, while the other is controlled by a thermostat. With proper selection of the power of the first heating element, the iron achieves a very steady, minimally-oscillating temperature by cycling the second element on and off in response to actual iron temperature during use, supplementing the first element as needed. Larger oscillations such as exhibited with single-element thermostat-controlled irons are avoided by the relatively smaller power of the second element, the only element cycled on and off, even when the thermostat is mechanical.

Abstract: A thermal activation device has a thermal head having heat generating elements for thermally activating a heat-sensitive adhesive layer of a heat-sensitive self-adhesive sheet. The heat-sensitive self-adhesive sheet has a sheet-like substrate having a printable surface on a first side thereof and the heat-sensitive adhesive layer on a second side thereof. An energy control device controls the thermal head by applying one or more voltage pulses to the heat generating elements for energizing the heat generating elements to thereby thermally activate an area of the heat-sensitive self-adhesive layer in one step. When a series of the voltage pulses are applied to the heat generating elements, the energy control device selectively switches between the heat generating elements to be energized by the voltage pulses each time one of the voltage pulses is applied.

Abstract: A base for warming massage nodes of a hand-held therapeutic device includes a housing, terminals connectable to a power supply, a seat for seating the massage nodes, and a heating circuit positioned to provide heat proximate to the massage nodes when the massage nodes are seated in the seat. The massage nodes can comprise an outer layer of stainless steel or iron and a core of material other than or in addition to air. The core absorbs or retains heat for a preferably gradual release over time. A method for warming such massage nodes includes selectively disposing the massage nodes in the housing adjacent to a heater, energizing the heater, permitting the heater to warm the massage nodes, and separating the massage nodes from the heater. The massage nodes can be separated from the heater by a magnetic extraction using the hand-held therapeutic device.

Abstract: A waveguide system for passing microwave energy while blocking foreign particles from a moving gas passing through the system is provided. The system includes first and second waveguide sections and a low loss microwave window disposed between the waveguide sections to allow microwave energy to pass from the first waveguide section through the window to the second waveguide section. The system also includes a gas bypass filtration system having a first port in communication with the first waveguide section, a filter element in communication with the first port, and a second port in communication with the filter element and with the second waveguide section. The system of the invention having these features blocks, by means of the window, a gas flowing through the first waveguide section and forces that gas to flow through the gas bypass filtration system so that it enters the second waveguide section only after passing through the filter. A system designed to include a pillbox window is also provided.

Abstract: An electric heater for gaseous media with at least one support plate and at least one helix of corrugated, electric resistance heating wire wound continuously around the support plate and whose turns are held by means of heating wire bend-offs on the longitudinal edges of the support plate is characterized in that the heating wire is positioned in such a way that it only contacts longitudinal narrow sides and/or edges of the longitudinal narrow sides of the support plate, the bending angle being much larger than 40°. This significantly reduces the risk of thermal damage to the heating wire, particularly in the vicinity of the plate edges. As a result of the largely naturally stable design of the heating wire, the heater according to the invention requires no spacers between the support plates and is therefore particularly simple and inexpensive to manufacture.

Abstract: An apparatus and method for manufacturing ultra-fine particles using an electrospray device is disclosed. One or more capillary provided at its tip with a nozzle is positioned within a guide duct and precursors such as metal organic materials and metal halogen compounds, or nonvolatile substances or volatile substances are supplied to the capillary.

The sprayed liquid droplets are carried along the guide duct together with carrier gas injected into the guide duct. When heat energy is applied to the liquid droplets, chemical reactions of the liquid droplets occur. A collecting plate positioned in front of the guide duct collects ultra-fine particles formed by the chemical reactions.
