摘要:
The present invention relates to a method of using foam to remove pollutants and/or heavy metals from a flowable media. The method may include providing a foam that may include cavities wherein the cavities may include an adsorbent composition of iron oxyhydroxy granules. The iron oxyhydroxy granules may have a BET surface area of >100 m2/g and a mean particle size of 0.1 mm-2 mm. The method may further include passing a flowable media containing pollutants and/or heavy metals through the foam wherein the pollutants and heavy metals may be removed from the flowable media by the iron oxyhydroxy granules. A method of manufacturing the foam is also disclosed. The method may include introducing an adsorbent composition into a liquid reaction composite to form a mixture and adding an isocyanate reaction component to the mixture to form the foam.

An electric hand-held power tool has a housing, a double-shelled handle attached axially to the housing, a selector ring pivotally located in the housing, an actuating element supported by the selector ring and swivelable manually, the housing and the handle including a line connecting domes oriented parallel to an axis of the housing and located in a parting plane region between the housing and the handle for receiving connecting units, the connecting domes including centering elements for guiding and exactly positioning handle shells when the handle shells are attached individually to the housing.
摘要:
The brushless direct current motor comprises a housing 10, a stator 13 and a rotor 11 within the housing, windings on the stator, sensors for sensing the position of the rotor relative to the stator and electronic circuitry for switching the current in the windings in response to outputs from the sensors to cause the rotor to rotate relative to the stator. The sensors and at least a part of the electronic circuitry are encapsulated in an electrically insulating and fuel resistant material in a container within the housing.
