摘要： A universal electric motor (1) for driving an electric hand-held tool device which experiences a high dust load, has a commutator (2), with carbon brushes (9) and lamellas (4). The motor has, for protection against dust particles carried along in the cooling air flowing through it, a protective shield (3) of a stiff and thermally conductive material.

摘要： The length of a column of a gaseous or liquid substance or of a solid bar is determined by generating a standing wave of known frequency, wavelength and/or wave velocity in the column or in the bar. The wave frequency is varied until at least two consecutive maxima (antinodes), two consecutive minima (nodes) or a minimum following a maximum of the amplitude of the standing wave have been detected. The length of the column of medium at known frequency and wave velocity of the standing wave generated in that column is computed from the equationL=c/[2(f.sub.n -f.sub.n-1)] (1),where L is the length of the column of medium, c is the wave velocity, f.sub.n is the frequency of the nth maximum and f.sub.n-1 the frequency of the (n-1)th maximum. Apparatus for implementing the method comprises a loudspeaker 1 mounted in a resonance chamber 2 with a tubular acoustic exit aperture 3. The resonance chamber 2 is mounted by a spacer 4 a distance from the pipe 6 containing the column of gaseous or liquid substance whose length must be determined. The spacer 4 also supports the receiving microphone 7. To keep the acoustic pressure constant over the frequency/wavelength range in the resonance chamber, the acoustic volume in this resonance chamber is kept constant by a regulator unit 11 with a control microphone 10.

摘要： An operating procedure for the motor (1) of an electric powered tool. The operating idle speed of the motor (1) is set to a value using regulator electronics (4), and the operating speed is the same as a chosen operating speed (n1). The motor (1) runs on a pre-determined and higher idle speed (n2) for cooling purposes after a specific idle time (ΔT). while the motor (1) runs on the pre-determined operating idle speed (n1). The engine speed is immediately set to the operating speed (n1) once again, when the motor requires a moment of strain at a certain period of time (T3) to maintain simple and comfortable operating procedures.

摘要： There is described a porous body for the storage and regulated release of vaporizable substances, which consists of open-pored sintered glass. The body preferably has a pore volume of from 30% to 85% and a mean pore size of from 10 to 350 .mu.m. The body is inert to the stored substances, has a very high storage volume and releases the stored substances very uniformly, and in particular, with no chromatography effects occurring.
