Abstract: Disclosed herein is a press-working apparatus, monitoring device, and method of operating a press-working apparatus with a press-working monitoring device and one or more displacement sensors configured to provide a first output signal indicative of deformation of the first sensing part. The method can be configured for determining if an error criterion based on the first output signal from the first displacement sensor has been met, and providing a control signal indicative of an error to the press-working apparatus if the error criterion is met.

Abstract: Press-working apparatus, monitoring device, and method of operating a press-working apparatus with a press-working monitoring device and one or more displacement sensors including a first displacement sensor comprising a first primary attachment part mounted on a first part of the press-working apparatus, a first secondary attachment part mounted on a second part of the press-working apparatus, and a first sensing part, the first sensing part being arranged between the first primary attachment part and the first secondary attachment part, wherein the first displacement sensor is configured to provide a first output signal indicative of deformation of the first sensing part is disclosed.

Abstract: The invention provides a pump with a transducer comprising a laminate with a film of a dielectric polymer material arranged between first and second layers of an electrically conductive material so that it is deflectable in response to an electrical field applied between the layers, wherein the laminate is arranged to cause a pumping action upon deflection of the film. The invention further provides a control system for a pump.

Abstract: The invention provides a power actuated valve comprising a transducer and a housing which forms an inlet for entering fluid into the valve, an exit for exit of the fluid from the valve, and a path between the inlet and the exit, the transducer comprising a laminate with a film of a dielectric polymer material arranged between first and second layers of an electrically conductive material. The film is elastically deformable in response to an electrical field applied between the layers, and the transducer is arranged relative to the path so that a ratio between deformation of the film and a flow condition in the path is established.

Abstract: A thermal expansion valve for a refrigeration system comprises a working element with a diaphragm clamped between a cover plate and a cover ring. The diaphragm is a multiple-diaphragm comprising two or more individual diaphragms. This makes the multiple-diaphragm more flexible than a single diaphragms and increases the lifetime of the diaphragm. The individual diaphragms are separated by an anti-friction layer to protect against tear, the anti-friction layer can be grease or oil placed between the individual diaphragms or it can be a layer of coating on the diaphragms.
