摘要:
A housing is provided for maintaining a planar lightguide circuit at a temperature within a predetermined temperature range independent of ambient temperature. The housing includes a planar heating arrangement supporting and in thermal contact with the planar lightguide circuit. Also included is a frame assembly having a first surface on which the planar heating arrangement is fixed. The frame assembly has at least one opening through which extends at least one optical fiber coupled to the planar lightguide circuit. An overmold, which is molded around the frame assembly, includes at least one strain relief member through which the optical fiber extends.

The invention concerns an air conditioning installation wherein longitudinal partitions (10, 11) run through by the heating radiator (5) define inside an air treatment housing (1) a median air volume (16) emerging through an outlet (40) connected to a rear zone of the vehicle passenger compartment and two lateral volumes (12, 14) emerging through outlets in the front zone of the passenger compartment. Thus, it is possible to adjust independently air temperature in the front and rear zones, with a more compact housing at economical production costs.

A heat exchanger that is useable in a wearable fluid heater is disclosed. Mechanisms may be used with or comprised in embodiments of the heat exchanger for purging gas from the heat exchanger.
摘要:
A gas sensor radiation source includes a filament in which microcavities having an opening diameter of about half of the absorption spectrum wavelength of a gas whose concentration is to be measured and a depth of twice or more greater than the opening diameter and a bulb enclosing, at a reduced pressure or with a noble gas enclosed therein, a filament. Thus, radiation can be efficiently made in accordance with the absorption spectrum of the gas to be detected.
摘要:
A method and miniature analytical device with thermal regulation of reactants using a localized heat source capable of emitting electromagnetic radiation, such as light emitting diodes (nullLEDnulls) and vertical cavity surface emitting lasers (nullVCSELnulls), generating internal heat, such as resistive, inductive and Peltier heaters, or external heating. The miniature analytical device comprises of array of temperature-controlled zones to restrict the volume heated and localize the heating by having the localized heat source comprise an array of emitters or heaters.
摘要:
A staircase construction is provided which may incorporate an integral heating assembly. The heating assembly is mounted within stair tread covers or repair members which may also be used to repair a damaged staircase. The staircase construction may further incorporate stair tread members of various configurations for attachment to standard stringers.
摘要:
The furnace comprises a tubular inner chamber for the treatment of the raw material, mounted inside the enveloping body of the furnace which is insulated from the exterior and is provided with internal resistor systems for heating the chamber of the furnace by radiation, comprising means for feeding raw material at one end and means for controlling the output of completed product at the other end of the treatment chamber of the furnace, inside which a worm screw, driven in rotation from the exterior, is mounted rotatably, respective percussion devices being incorporated in the ends of the screw to prevent compaction of the mass on the screw.
摘要:
A cable connector for a direct heating cable system for a pipeline (4) where a direct heating cable is connected to the pipeline at two remote points, the cable (3) comprising a cone (1) connected to the end, the cone (1) comprising means for connecting releasably a bolt (9) coaxially to the cone (1), a pulling wire (7) being secured to the bolt (9) adapted to pull the cone (1) and the cable (3) into a connector (2) secured to the pipeline and having an inner shape corresponding with the outer shape of the cone (1), the connector (2) being adapted to lock the cone (1) to the connector (2) and release the pulling wire (7) from the cone (1).
