Cable coiling device for electric heaters
The present invention relates to an improved cable coiling device
for electric heaters comprising a cable coiling frame being built
in the casing at where the exit of the power cable locates; and
an accommodating hood being disposed on the periphery of the coiling
frame according to the casing appearance and such accommodating
hood works with a linking member which turns the cable coiler on
and off by lifting up the linking member to coil the power cable
thereby the coiled cable will not be exposed and hence gives an
artistic, reliable, convenient, and safe effect.
Refsicoat heat resistant material and high-temperature electric
heaters using said material
The present invention relates to the provision of materials intended
for use in an oxidative medium at high temperatures, including the
manufacture of high-temperature electric heaters, parts, sensors
and tools operating at temperatures of up to 1900.degree. C. and
higher. On the basis of suicides--solid solutions (Mo,W).sub.5 Si.sub.3
and (Mo,W)Si.sub.2 as well as Novotny phase (Mo,W) .sub.5 Si.sub.3
C containing molybdenum and tungsten, a heat-resistant material
is proposed, which makes it possible to produce parts fully made
therefrom and a broad range of other heat-resistant materials for
the provision of protective coatings and soldered joints: "REFSIC"
composite materials, carbon, silicon carbide materials, refractory
metals and their alloys. Extensive property-varying potentialities
by controlling the phase composition, a large diversity of the structural
features of single-layered and multilayered protective coatings
make it possible to control the heat-resistance, resistance to thermal
shocks and resistance to combined thermal deformations of the coating
as such and of parts produced by soldering other high-temperature
materials with the help of the proposed heat-resistant material.
The proposed electric heaters can have working parts and current
lead-in wires made from the above-mentioned high-temperature materials,
having soldered joints and protective coatings prom the proposed
material in different combinations of materials and heater designs.
Controller for electric heaters for internal combustion
engine
This invention pertains to a controller for electric heaters for
preheating temperature sensitive components of internal combustion
engines operating in very cold climates. The controller reduces
energy consumption by turning on the engine component heater no
sooner than necessary for the object to achieve the desired temperature.
The device monitors ambient air temperature and when it is cold
enough, projects the rate of the change of temperature forward to
predict the temperature at the time the engine must next be started.
Using manufacturers' heater specifications, the air temperature
ambient to the engine components and an heating function derived
from heat conduction theory, the device calculates the amount of
time required for heating the engine components and turns on the
heater when the appropriate time arrives. For vehicles going into
service on fixed daily schedules, the controller automatically controls
the start and duration of heating without user intervention for
both daily and weekend schedules. A key pad and display panel allow
entry and verification of data for each heater, including desired
use time(s) for each day of the week, vehicle/heater circuit identification,
and the heating time parameter for the engine/heater.
