Abstract: Self-regulating electrical heating systems which comprise a constant voltage or constant current power supply and at least one heating unit which comprises a reactive component, a resistive heating component, and a temperature-responsive component. Preferably the reactive component and the temperature-responsive component are combined in the form of a capacitor comprising a dielectric whose dielectric constant decrease with temperature or an inductor comprising a core whose permeability increases with temperature.

Abstract: A continuous flexible cable-type immersion heater for heating liquid in a container having a heating elementformed of electrical resistance wire coiled in axially spaced pitches of uniform diameter with a braided sheath of glass fiber material received over the coiled element in closely fitting free sliding engagement. A thin wall continuous tubular Teflon ® PFA jacket is received overthe braided sheath in closely fitting free sliding engagement. Conduit means are attached in fluid sealing attachment to the ends of the jacket and purge of dry gaseous medium is circulated from one end of the heater to the other inside the jacket for removal of chemical vapors for protecting the heating element. In one embodiment, a thermocouple encased in thermosetting plastic is disposed between the braided sheath and the plastic cable jacket for quick sensing of over temperature upon loss of container liquid.

Abstract: Method for monitoring the electrical integrity of a heater and a novel heater for use in such a method. The heater includes an elongate heating member; an insulating jacket which encloses the heating member; a first electrically conductive member which surrounds the insulating jacket; a separating and insulating member which surrounds the first conductive member; and a second electrically conductive member which surrounds the first conductive member and is separated and insulated therefrom by the separating member. The method includes the step of testing the electrical relationship between the first and second electrically conductive members. A useful electrical circuit for implementing the method is shown in Figure 2.

Abstract: A heat tracing tape which can be cut to required lengths has a heating element comprising at least two lengths of woven or braided resistance wire each in the form of a flat strip. The strips are encased in extruded silicone rubber whereby they are spaced from one another. The strips are electrically connected at one end by a connector and the tape is provided with a power supply termination either at its other end, or at a T-branch connection, for connecting the tape to the power control system. The power control system is adjustable to set an estimated value of power required to maintain a predetermined process temperature. The system automatically adjusts the power supplied to the tape to the estimated value by means of a feedback control system. A process temperature sensor also regulates the power supplied to the tape in accordance with a sensed temperature.

Abstract: Disclosed are improved melt processable, self-temperature regulating, irradiation cross-linkable, electrically semi-conductive polymeric compositions (5) which in conjunction with annealing at a temperature at or above their melt point temperatures subsequent to their having been radiation cross-linked provide for improved self-temperature regulating electrical heating devices (1) including flexible electrical heating cables. Heating cables (1) made in accordance with the invention comprise two or more elongate substantially parallel spaced-apart electrical conductors that are electrically interconnected by means of extruded forms of the compositions which have been annealed at a, temperature at or above their melt point temperatures prior and subsequent to their having been cross-linked by irradiation. The compositions of the invention have an amount of electrically conductive particles, such as carbon black, dispersed therein, that is controlled within the range of 17% to 25% by weight to the total weight of the compositions.
