Abstract: Disclosed is a method for determining the sound velocity (Cb) in a basic material, in which an ultrasonic probe comprising a transmitting probe, a receiver transducer, and a forward member is used. Said forward member is provided with a coupling surface, by means of which the probe is coupled to the basic material, and has a sound velocity (Cv). The transmitting probe and the receiver transducer are maligned in an oblique manner from each other and from the coupling surface such that a main transmission direction of the transmitting probe and a main receiving direction of the receiver transducer intersect below the coupling surface. The centers of the transmitting probe and the receiver transducer are located at a distance K from each other and are located at a distance Dv from the coupling surface. According to the inventive method, the transmitting probe generates an ultrasonic pulse which runs through the forward member into the basic material, where said ultrasonic pulse creates a creeping wave, a portion of which arrives at the receiver transducer. The shortest sound traveling time (Ttot) is measured and the sound velocity (Cb) within the basic material is determined via the path between the transmitting probe and the receiver transducer, which supplies the shortest total traveling time (Ttot).

Abstract: A dispenser for dispensing a soap product includes a soap pump, a dispensing nozzle, and an expandable and contractible suction chamber. The dispensing nozzle has an outlet for dispensing soap, and the suction chamber is disposed between the soap pump and the dispensing nozzle. The suction chamber is expandable and contractible in volume and is predisposed to an expanded volume. Actuation of the soap pump causes the suction chamber to contract to a contracted volume that is less than the expanded volume to which it is predisposed, and soap is forced through the suction chamber and the dispensing nozzle to the outlet where it is dispensed. Soap that has not been dispensed at the outlet resides in the dispensing nozzle after actuation of the soap pump, and this residual soap is sucked back into the suction chamber during a return of the suction chamber to the expanded volume to which it is predisposed.
