  • Patent number: 12208409
    Abstract: The invention provides a head for a fluid excitation device in which a transducer comprising a vibration generation portion and a fluid excitation portion is secured to a flexible substrate using an adhesive layer located between the vibration generation portion and the flexible substrate. An external force-applying structure is not needed to secure the vibration generation portion to the fluid excitation portion, removing a cause of significant vibration damping. Rather than damping the vibrations generated by the transducer, the flexible substrate instead itself moves in co-operation with the transducer, reducing damping effects. The design and manufacture of this arrangement is relatively simple and no complex tuning is required to ensure efficient operation over the entire operational life of the head. The head can be used in a fluid excitation device such as an atomiser or ultrasonic bath.

  • Patent number: 12201862
    Abstract: An extinguishing lance for electrical devices that are burning, has a holding portion having a handle part for operation, an extinguishing-agent feed having a coupling device for connecting a pressure hose for extinguishing agent, and a tubular extinguishing portion, from the free end of which extinguishing agent is introduced, under pressure, into the object that is burning. The extinguishing portion tapers to a point at the free end and has a constricted, hollow flow cross-section for extinguishing agent conducted under pressure. The extinguishing portion and its tapered, additionally hardened end are produced from stainless steel. The extinguishing portion has, at least in the region of the holding portion, a voltage-insulating coating, which is electrically insulating for electric voltages U?500 V. Thus, the minimum legal requirements for protection against thermal hazards, against mechanical overloads, and against electrical hazards are reliably met.

  • Patent number: 12145166
    Abstract: The disclosure relates to a rotary atomizer for applying a spray jet of a coating agent (e.g. paint) to a component (e.g. motor vehicle body component). The disclosure provides that the construction dimensions of the rotary atomizer are coordinated in such a way that the air pressure at the outlet opening of the paint nozzle during operation is lower than the air pressure in the nozzle chamber of the bell cup and in the external rinsing channels in order to prevent a backflow of the coating agent from the outlet opening of the paint nozzle backwards in the direction of the nozzle chamber due to the pressure difference.
