Abstract: A device for warming a shoe is disclosed. An insole has a top cavity. A releasable shoe pad includes a top padding member and a recess between forward and rearward bottom portions. The device includes a thin metal member formed on the pad and including an intermediate conductive member, a forward conductive section extended from the conductive member, and a rearward conductive section extended from the conductive member, and a heater unit fastened in a space defined by the recess. The heater unit includes a fuel chamber, a combustion chamber filled with zirconia fibers, and a channel interconnected the fuel and the combustion chambers, the channel including fibers and a wick having one end immersed in the fuel chamber and the other end connected to the fibers.

Abstract: The present invention provides an apparatus for heating water. In certain embodiments, the present invention relates to a portable apparatus for heating water that may also be self-contained such that connection to additional sources of fuel or electrical power are not required. Certain embodiments of the present invention may be used to provide heated water for showers, cleaning, food preparation, and the like.

Abstract: A heated cushion particularly for stadiums and sports and recreational activities, comprising a body inside which a seat is formed for accommodating a container which is meant to be filled with hot water to diffuse heat from the inside of the cushion toward its outer surface.

Abstract: A temperature control apparatus for a bed includes at least one heating element, mounted in a resting surface on a mattress of the bed for warming at least a first are(a of the resting area. A temperature sensor is located to detect the temperature of the first area of the resting area, and transmits the information to a central control unit. The central control unit includes a central processing unit which is interconnected with both the heating element and the temperature sensor to adjust the temperature in the first, area of the resting area as desired. The central control unit is also connected to a timer to permit programming of temperature changes as desired. An occupant sensor in the resting surface of the mattress will detect the presence and absence of an occupant, and transmit this information to the central control unit for processing.

Abstract: A heat pack for use as a warmer mattress for infants is formed of a flexible container at least partly filled with a supercooled aqueous salt solution which is selectively trigger-activated to produce heat by exothermic crystallization. The container is compartmentalized, being divided into several compartments by a heat-sealing arrangement of upper and lower joined halves. When crystallization is initiated by activating the trigger, crystallization is propagated quickly into the several compartments, from each of which heat is thereby liberated, the compartments being shaped such that the crystallizing solution in each compartment is effectively trapped therein to substantially prevent saddle-bagging, and whereby the heat pack reliably and safely supports an infant upon the warmer mattress. The upper and lower halves are heat-sealed together in various possible heat seal patterns defining the compartments, as by sealed margins and heat-seal extensions extending inwardly from the peripherally margins.

Abstract: A backpack-transportable, heated sleeping bag ground pad is provided for the hiker/camper which is extremely compact, simple to use and which may incorporate a variety of conventional outdoor heat sources, such as a campfire or simple kerosene or alcohol lamp, for example. The system basically includes a heating reservoir and miniature, battery-operated pump system to circulate heated water through flexible plastic tubing embedded in a standard sleeping bag ground pad.

Abstract: A thermoelectric heat pump or power source device is provided with P-type and N-type elements made of either thin films or thick films for use on flexible or nonflexible substrates. For flexible units the film type elements are formed on substrates of such flexible, electrically insulation material as, for example, MYLAR and TEFLON; while for inflexible units the elements are formed on substrates of such materials as, for example, Beryllia, Alumina, ceramics, or plastics. Further, the elements are patterned on the different substrates for particular usages. For example, radial element patterns are used for cooling hot spots and ladder element patterns are used for cooling linear hot bodies. Ladder element patterns may also be used on flexible substrates to be folded to form corrugations having cold strips and hot strips on opposing sides to which sheets of suitable material can be attached to form panels, blankets, therapeutic devices or pipe coverings for heating or cooling their contents as desired.

Abstract: A bed clothes drying device comprises a hot air supplier having a blower and a heater which is connected to an air inlet and a hot air outlet and a bag which is connected through a joint pipe to the hot air outlet and filled out under a blow pressure given by feeding a hot air from the hot air supplier to discharge the hot air through the sheet of the bag and which has flexibility and air-permeability with a resistance of 1.75 to 3.75 mmH.sub.2 O to air flow of 0.7 to 1 m.sup.3 /min. The bag is disposed between a bed and a coverlet to dry the bed and the coverlet with the hot air and the bag has an improved structure.
