Abstract: A storage fluid heater for heating a fluid, employs a heat storage unit, a heating element thermally coupled to the heat storage unit, and a heat recovery tube thermally coupled to the heat storage unit. The recovery tube is made from a material having a coefficient of thermal expansion so that as the average temperature of the heat storage unit near the heat recovery tube increases, the surface area of gaps between the heat recovery tube and the storage unit increases, causing the contact resistance between the heat storage unit and the heat recovery tube to increase. The temperature of the fluid flowing within the heat recovery tube is thereby limited to a predetermined maximum. A structure that relieves excess pressure when the flow of fluid through the tube is stopped has an expansion tank connected to the fluid inlet of the tube.

Heaters of different temperatures are provided by choosing heaters with ferromagnetic materials having different Curie temperatures. The structure is used as a soldering iron by inserting a heater with a proper shape in one arm and short circuitry the connector in the other arm.

Abstract: A low wattage device for heat-liquefying material is described which employs a low volume mass electrical heat exchanger structure to generate a high power density within a dispensing tip; and simultaneously by actuation of an operator controlled momentary on/off switch for energizing the heat exchanger structure heater, the heat-liquefiable material is pressed into effective contact with the heat exchanger structure. The heat exchanger structure is formed by positioning a resistive heating element in contiguous relation to the outer wall of a low volume thermal conducting mass formed into a heat-liquefying material conductor and generates sufficiently high heat at a relatively low wattage to effectively achieve the desired melting within a few seconds. In a further feature, an insulating shield partially envelopes the heat exchanger structure to prevent contact with the resistive heating element and to minimize heat loss.

Abstract: A computer pad is heated for reducing repetitive motion stress and increasing comfort for a user and for providing potential therapeutic treatment by warming the hand(s) and/or wrist(s) of the user while operating a computer input device such as a mouse or a keyboard. The pad includes an electrical heating device such as a resistance-type heating element embedded in it. If a mouse is used as the input device, it can be either a stationary mouse or a conventional movably positioned mouse that is operated on the level section of the top surface of the pad's upper layer. If a stationary mouse or a keyboard is utilized, the user's hand(s) and/or wrist(s) can be supported by a suitably shaped area within an elevated section of the working surface of the pad. The lower layer of the pad may conveniently include a non-skid bottom surface.

Abstract: A new deicing technology is described which utilizes the actuating properties of shape memory alloys (SMAs) to debond ice accretion formed on a surface. A thin sheet of SMA material is mounted to the icing prone surface to perform the force and displacement combination that can debond the ice. The SMA sheet is activated to expand or contract causing shearing and peeling of the ice. An SMA actuator portion located aft of the icing area can be used to pull the sheet over a ribbed underlay and grooved bands which generates a strain field that severs the ice's adhesive bond. Two-way shape memory action and natural ice latent heat powering are used in different modes of operation to reduce the power requirements and the structural complexity of the deicing system.

Abstract: A soldering tip is disclosed which fits loosely over a ceramic heater rod. The rear skirt of the tip is slotted into segments the rear edges of which are tapered rearwardly inwardly to be engaged by a forwardly opening conical surface on the front of a metallic sheath covering and supporting the rear portion of the ceramic rod. When the soldering tip is urged rearwardly in its assembly to the remainder of the soldering tool the segmented portions of the skirt are then pressed radially inwardly over the ceramic rod. The slots dividing the skirt into segments extend well forwardly thereof whereby the bending of the segments is forwardly of the tip of the ceramic rod where a thermocouple type temperature sensor may be disposed. Thus the skirt portions make good thermal contact with the rear and central portions of the ceramic rod but not with the temperature sensor front tip portion.

Abstract: A hair curler system in which a number of hair curlers and curler lifters are stored in individual compartments insulated with respect to one another and with respect to the outside to thereby effectively improve energy efficiency of the curler system. The individual compartments are formed by cored-out insulation or by individual heat tubes either of test-tube-like shape having an open or closed bottom or of an inwardly recessed bottom to receive heat posts or rods on a heat plate or accommodate lossy dielectric material.

Abstract: A heating element has a flat, flexible strip of electrically insulating material around which is wound a conductor wire. A layer of fixing varnish covers the turns of the conductor wire and the flat strip. Two clips attached to the ends of the strip provide electrical contact with the conductor wire and serve to attach two electricity connection cables. The heating element can be bent without this affecting its ohm value since the fixing varnish prevents the turns of the conductor wire from moving when the strip is being bent.
