  • HELMET
    Publication number: 20220378139
    Abstract: A helmet attachment system (5, 31) comprising a helmet (1), a net (5) arranged on the helmet (1), and a helmet attachment arrangement (31). The helmet attachment arrangement (31) has a base layer (33) and an attachment layer (35). The attachment layer (35) is attached on one face of the base layer (33). The attachment layer (35) comprises a plurality of attachment layer sections (35a) that have a mutual distance and that define a string-receiving pattern (37) configured to receive strings (9) of said net (5).

  • Ultrasound sensor system
    Patent number: 7203133
    Abstract: The invention relates to an ultrasound sensor system, especially for a welding electrode, comprising a sensor (5, 6, 7, 10) which, during the detection process, passes ultrasonic waves of a desired oscillation mode into areas to be detected and/or detects ultrasonic waves. At least one material recess (2) is provided in a sensor support (1), and at least one sensor (5, 6, 7, 10) is arranged in said recess.

  • Ultrasonic sensor for controlling the process during resistance spot welding
    Patent number: 7197933
    Abstract: A sensor carrier is provided that has at least one oscillating element (32) that introduces ultrasonic waves into an area to be examined and/or receives ultrasonic waves coming from the area to be examined, whereby the oscillating element (32) is located in an oscillator carrier (33), and the oscillator carrier (33) has connecting means (36, 37, 38, 39) for connection with the electrode (31).

  • Ultrasonic sensor system for horizontally polarized transversal waves
    Patent number: 7055388
    Abstract: The invention relates to an ultrasonic sensor system, especially for controlling a resistance welding process. Said system comprises at least one receiver which is used to detect the ultrasonic signals from the area to be examined. At least two piezoelectric sensors (31, 32) are used as a receiver and are arranged in such a way that their polarization direction vectors indicate various directions, said vectors being projected in a plane perpendicular in relation to the propagation direction of an ultrasonic wave to be detected.
