    摘要： A safety device for an apparatus to be manipulated by an operator. The apparatus is connected via a supply line for a supply means to a supply means source. A handgrip is provided to be grasped by the operator for controlling the operation of the apparatus. An operating sensor is actuated by the operator and is connected to the control device. The operating sensor may be an electric proximity switch provided so that it is possible to shut off the apparatus when the operator ceases to actuate the operating sensor. The operating sensor, or at least one indicator element of the operating sensor, is disposed on the hand of the operator, particularly integrated into a protective glove for the hand of the operator.

    摘要： For sand blasting a stream of a suspension of a carrier gas and solid particles under superatmospheric pressure is restricted so that it is accelerated, and a liquid-carrying additive gas is mixed with the stream to moisten the particles. The additive gas is introduced into the stream at a pressure greater than the pressure of the stream at the location by between 1.5 and 2.5 times. Normally the additive-gas pressure is about twice the carrier-gas pressure, that is the additive gas is normally introduced at a pressure of between about 10 bar and 30 bar. This high-pressure introduction ensures that the additive gas enters well into the carrier-gas stream so that the liquid carried by the additive gas contacts and wets the solids carried by the carrier gas without just passing through it and wetting the inside of the sand-blast mix nozzle. The additive gas is introduced into the stream in a unit of time at a rate sufficient to introduce into the stream a quantity of the liquid equal to between about one-twentieth to one-thirtieth, preferably one-twenty-fifth, the mass of the particles passing the location during the unit of time.
