A method for determining the degree of wear of a valve, the degree of wear of the valve being dependent on the degree of wear of an operating element that is made of an expandable material and performs a mechanical movement each time the temperature changes, the change in temperature resulting in wear, the operating element made of an expandable material being mechanically connected to a piston; the movements of the operating element made of an expandable material are calculated by initially sensing the change in temperature on the operating element, whereupon the changes in temperature are recalculated as movements on the basis of the temperature/expansion curve applicable to the operating element made of an expandable material.

Method for determining the degree of wear of a valve, and apparatus for carrying out said method

Disclosed is a method for determining the degree of wear of a valve, the degree of wear of the valve being dependent on the degree of wear of an operating element that is made of an expandable material and performs a mechanical movement each time the temperature changes, the change in temperature resulting in wear, the operating element made of an expandable material being mechanically connected to a piston; the movements of the operating element () made of an expandable material are calculated by initially sensing the change in temperature on the operating element (), whereupon the changes in temperature are recalculated as movements on the basis of the temperature/expansion curve applicable to the operating element () made of an expandable material.

Disclosed are drive systems for a vehicle trailer maneuvering drives, some embodiments having a motor unit and a voltage source for supplying the motor unit, wherein the motor unit comprises a brushed electric motor with motor shaft and a motor controller that may include a speed detection unit for detecting the speed of the motor shaft and a control and regulating unit for the motor, for its voltage supply.

Drive system for a vehicle trailer maneuvering drive

A maneuvering drive () for a trailer () has a central unit (), at least two drive units () by which wheels () of the trailer () can be driven and which are controlled by the central unit (), each drive unit () including a checking module () by which drive specifications of the central unit () can be checked as to whether they can be fulfilled, and a feedback channel being provided by which the drive units () can feed back to the central unit () if the drive specifications cannot be fulfilled.

Maneuvering drive with smart central unit

A handler for electronic components, in particular IC's, comprising a feed unit for plungers with a pneumatic cylinder unit that can be displaced and that is coupled to a pneumatic cylinder displacement unit, which moves said cylinder unit back and forth in the axial direction of the plungers.

Handler for electronic components, in particular IC'S, comprising a pneumatic cylinder displacement unit for moving plungers

The invention relates to a handler for electronic components, in particular IC's, having a plurality of circulating carriages () that are guided along their circulating track by means of a stationary, annular guide device () consisting of at least one circulating guide rail. Retaining units () are provided on the circulating carriages (), said units retaining the components () to be tested.

A plunger for holding and moving electrical components in particular IC's to and from a contacting device connected to a test bed, comprises a head piece with a fluid distribution chamber through which temperature-controlled fluid flows. A suction head is arranged such that the temperature-controlled fluid flows around the suction head and is diverted along the suction head to the component.

Plunger for holding and moving electronic components in particular ICS

A handler for electronic components, in particular IC's, for controlling the temperature of the components and supplying and removing said components to and from a test device has circulating units that can be moved along a circulating track. Each unit has at least one retaining unit for retaining a component. In addition, the circulating units have temperature-control chambers containing components that are retained by the retaining units, so that the temperature of the components can be controlled during transport from the charging station to the test station.
