20150115044 | THERMOSTAT UNIT - Disclosed is a thermostat unit having at least two thermostats, which are held at a normed rail. The two thermostats are arranged transversely to the rail axis. | 04-30-2015 |
20120315024 | ELECTRIC HEATER - The invention relates to an electric heater comprising a fluid-conducting housing, in which at least one, preferably helical, heating unit, preferably a wire resistance heating element, is accommodated. The heating unit can have a tubular outer body, in which a heating element electrically contacted with a control circuit accommodated in an electronics housing is embedded. According to the invention, end sections of the heating unit extend in a sealed manner through the fluid-conducting housing to, and preferably into, an electronics housing. The invention further discloses a method for actuating an electric heater and to a heater that can be operated according to such a method, wherein said heater is designed with at least one resistance heating element, which acts as a temperature sensor, so that the temperature thereof can be used for actuating the heater. | 12-13-2012 |
20120227280 | DRYING OF WATER DAMAGED BUILDINGS - A drying apparatus for temporary location within a damp or waterlogged room is disclosed. The apparatus includes sensors to sense the level of temperature and humidity within the room, a heater to provide heat for the room, an air circulation fan for selectively circulating heated air within the room or selectively exhausting warm and humid air from the room and for allowing outside ambient air into the room. The apparatus being adapted to cyclically continue until the sensed humidity reaches a required level, the apparatus thereafter indicating, directly or indirectly, the completion of the drying process. A method of drying a room using such apparatus is also disclosed which employs a technique whereby the rate of change of the temperature increase is used to determine when humid air should be exhausted from the room. A time limit can also be use to determine when said exhausting takes place. | 09-13-2012 |
20110147374 | ELECTRIC HEATING APPARATUS FOR HEATING INFANT FOOD BY MEANS OF ELECTROMAGNETIC RADIATION - The present invention relates to an electric heating apparatus comprising a casing in which a receptacle containing a substance to be heated, preferably infant food, can be at least partly received. In the casing a radiation source for emitting electromagnetic radiation is arranged and the heating apparatus further comprises at least one reflector disposed in such way that it directs the emitted electromagnetic radiation onto the substance to be heated. In accordance with the invention, the reflector forms a hollow by which the receptacle can be at least partly received for heating, the radiation source being arranged with respect to the reflector such that a predominant portion of the electromagnetic radiation which is not directly incident on the receptacle is directed to the receptacle by the reflector. | 06-23-2011 |
20090183778 | TANK WITHDRAWAL SYSTEM WITH ELECTRIC AND FLUIDIC HEATING DEVICE - The invention relates to a tank withdrawal system for a vehicle tank filled with a frozen liquid. The tank withdrawal system comprises a heating system comprising at least one electric heating element as primary heating device and a conduit system provided with at least one withdrawal conduit with a withdrawal opening arranged in the vehicle tank. The cold start volume of the frozen liquid extending around the withdrawal opening can be melted by the primary heating device. To quickly melt a cold start volume while melting off the remaining frozen liquid consuming as minimal amount of energy, the heating system comprises a secondary heating device supplied with a heating fluid and the conduit system comprises at least one heating conduit through which the heating fluid can flow and which is arranged in the liquid in the vehicle tank. | 07-23-2009 |
20080266047 | Power resistor module - A power resistor module for electrical circuits has at least one resistor element and at least one housing element. The at least one resistor element is mounted at least section-wise between two electrically insulating, thermally conductive insulation elements in the housing element. The insulation elements at least section-wise abut against the at least one housing element. Methods for producing an electrical power resistor module for an electrical circuit include compressing, at least one resistor element with two electrically insulating, thermally conductive insulation elements. At least one of the two insulation elements is pressed at least section-wise against a housing element. If a wire is used as the resistor element, the use of possible fillers such as magnesium oxide may be waived by providing that the wire abuts at least section-wise against at least one of the two insulation elements during the compression. | 10-30-2008 |
