摘要： A preinsulated pipe assembly and pipeline formed from a plurality of such assemblies. Each pipe assembly includes a pipe with a heater housing mounted thereon to form a cavity along the exterior of the pipe and a preformed insulation layer for insulating the pipe and the heater housing. A connecting assembly is used to join the pipe assemblies and form a pipeline. Pull means detachably connected to a heating element facilitates placement of the heating element in the heater housing cavities, and a pulling assembly attached to the heater element permits removal of the heater element after installation of the pipeline.

摘要： An electrical heating cable which limits power output once an established temperature limit is reached. The cable includes heating elements in the form of temperature-sensitive variable resistance elements electrically connected in parallel between two supply bases at spaced positions along the length of the buses. The heating elements not only serve to generate heat for heating but also undergo a substantial positive increase in resistivity when the temperature of the cable nears the established temperature limit. The increase in resistivity substantially reduces the heat-generating current in the cable to limit the power output to within established heat limits.
摘要翻译： 一旦达到建立的温度限制，就限制功率输出的电加热电缆。 电缆包括温度敏感的可变电阻元件形式的加热元件，该可变电阻元件在沿着总线长度的间隔位置处并联电连接在两个电源基座之间。 加热元件不仅用于产生加热的热量，而且当电缆的温度接近建立的温度极限时，电阻率也会显着增加。 电阻率的增加大大降低了电缆中的发热电流，将功率输出限制在已建立的热限度内。

摘要： A pipe heat transfer assembly adapted to be easily and rapidly installed with unskilled in the field on a pipe to be heated or cooled includes an elongated rigid channel cover member and a separate elongated, preshaped, solid, flexible strip of thermoplastic resin heat transfer material having a first surface preshaped to conform closely to the inner cavity surface of the channel member and a second surface preshaped to conform closely to the shape of the pipe surface on which it is to be mounted. The strip of heat transfer material may be pre-shaped by molding or extruding. An elongated heat transfer element, which may be an electric heating wire or an elongated tube for a heat transfer liquid to flow therethrough, is embedded in the strip during such pre-shaping. Alternatively, a space for reception of the heat transfer element can be formed in the strip during the pre-shaping of the strip and the element subsequently installed in the space. The thermoplastic heat transfer material after preshaping remains solid and flexible without any significant flow within the temperature range of from about 10.degree.F to about 120.degree.F.

摘要： Pipe heat transfer assembly and method of making same, wherein a strip of heat transfer material is pre-shaped to a solid flexible form for closely .[.comforming.]. .Iadd.conforming .Iaddend.with a heat transfer element for either heating or cooling and which is also pre-shaped to fit closely within an external channel member, whereby the entire assembly may be more easily and rapidly installed with unskilled labor in the field on a pipe to be heated or cooled, using retaining band means as the holding means for the assembly, with the assurance of complete coverage of the heat transfer element by said heat transfer material so as to eliminate air gaps. The heat transfer material may be pre-shaped by molding or extruding, with the heat transfer element embedded therein during such pre-shaping, or with a preformed space for the heat transfer element. The heat transfer material is solid, capable of retaining its shape, and remains flexible, after pre-shaping, within the normal temperature range to which the material is subjected, preferably within a range of from about 10.degree. F. to about 120.degree. F.

摘要： An electrical heating cable which limits power output once an established temperature limit is reached. The cable includes a high-resistance element and a temperature-sensitive variable resistance element electrically connected in series between two electrical conductors otherwise insulated from each other by insulating material. The temperature-sensitive resistance undergoes a substantial positive increase in resistivity when the temperature of the cable nears the established temperature limit. The increase in resistivity substantially reduces the heat-generating current flowing in the cable to limit the power output.

摘要： A mounting apparatus for releasably securing an external member to a tubular member having a resilient, curved clamp member with open ends. The curved clamp member extends for more than 180.degree. but less than 360.degree., having a diameter less than the diameter of the tubular member prior to mounting the curved clamp member to the tubular member. The curved clamp member further includes a mounting portion opposite the open ends for engaging an external member for holding the same securely to the tubular member.
