摘要:
A paraffin bath apparatus for melting paraffin used in therapeutic applications is disclosed. The paraffin bath apparatus comprises a housing having a base, a sidewall and upper opening. An inner tub is formed of a temperature resistant polymeric material is a generally cup shaped member having a bottom wall, an upstanding wall and an open top. The inner tub is received within the upper opening of the housing with the bottom wall of the inner tub overlying the base of the housing. The heating element is located between the inner tub and the housing for providing heat to the inner tub sufficient to melt the paraffin but below the temperature that would adversely affect the polymeric material forming inner tub. A thermostatic sensor is disposed between the inner tub and the housing and is electrically connected to the heating element to control the heat provided to the inner tub. A temperature indicating element may be provided in the inner tub and placed in contact with paraffin melted in the inner tub. The temperature indicating element provides a visual indication that the paraffin in the tub is within a predetermined temperature range and is visible through the melted paraffin.

An apparatus for heating water is provided having a water receptacle including a bottom wall and side walls for containing a volume of water therein to be heated. The bottom wall of the receptacle has an exterior surface and an interior surface proximate the volume of water to be heated. The water is heated by a heater contained within the water receptacle and secured to the interior surface of the bottom wall of the receptacle by a securement pin which extends through the bottom wall and is threadably engaged with the heater. The heater is elevated from the interior surface of the water receptacle by a collar of high insulation material which is received within a peripheral groove portion of the heater such that the tightening of the securement pin compresses the rubber collar to create a seal between the heater and the bottom wall of the water receptacle. In addition, the elevating collar serves as a barrier between the heater and the bottom wall such that the heater is not in direct contact with the water receptacle wherein in the event of overheating, the heater does not melt or burn the water receptacle.

An electric heating pad is provided, the heating pad having a conductive sheet, the conductive sheet provided with an elongated opening and a perimeter. The conductive sheet is comprised of a flexible and pliable material so that the conductive sheet is capable of following and adhering to the contour of the surface of the human body when applied thereto. A first sheet material, having a seal area disposed on the first sheet material and a perimeter larger than the perimeter of the conductive sheet so as to extend over the conductive sheet to define a sealing edge is provided. A second sheet material, having a seal area disposed on the second sheet material and a perimeter larger than the perimeter of the conductive sheet so as to also extend over the conductive sheet to define a sealing edge is also provided. In this way, when the conductive sheet is placed between the first and second sheet material and when the sealing edges of the first and second sheet material are aligned together, the sealing area and the sealing edges of the first sheet are adhered together with the sealing area and the sealing edges of the second sheet so that the conductive sheet is sealed within the first and second sheet material to define a water-tight pouch.
摘要:
A refrigerated beverage dispenser. A beverage container is carried in a covered refrigerated housing that includes a heat exchanger for maintaining beverage at a predetermined temperature. A dispensing tube provides a conduit for the beverage. To dispense the liquid, a pressure differential is produced whereby the pressure on the liquid in the container is greater than the pressure at a dispensing port.

A paraffin bath apparatus for melting paraffin used in therapeutic applications is disclosed. The paraffin bath apparatus comprises a housing having a base, a sidewall and upper opening. An inner tub is formed of a temperature resistant polymeric material is a generally cup shaped member having a bottom wall, an upstanding wall and an open top. The inner tub is received within the upper opening of the housing with the bottom wall of the inner tub overlying the base of the housing. The heating element is located between the inner tub and the housing for providing heat to the inner tub sufficient to melt the paraffin but below the temperature that would adversely affect the polymeric material forming inner tub. A thermostatic sensor is disposed between the inner tub and the housing and is electrically connected to the heating element to control the heat provided to the inner tub. A temperature indicating element may be provided in the inner tub and placed in contact with paraffin melted in the inner tub. The temperature indicating element provides a visual indication that the paraffin in the tub is within a predetermined temperature range and is visible through the melted paraffin.

摘要:
A heating element for heating liquids, comprising a heating coil coiled about a central axis. The coil has a first end and a second end lying in a plane substantially parallel to the central axis. The coil is covered with insulation which is covered with a protective sheath. The protective sheath is covered with an aluminum housing provided with a central aperture to increase the surface area of the heating element in contact with the liquid to improve start-up time. The aluminum housing is also provided with an aperture to receive a thermostat. A pressure die having a first portion and a second portion is adapted to receive a spacer between the first and second portions to vary the distance between the first and second portion and allow for the manufacture of heating elements of varying diameters.
