Abstract: An extension table (2) comprises a plurality of extension rails (4, 6) along the table (2) for adjusting a dimension of the table (2), wherein an extension rail (4) of the plurality of extension rails (4, 6) comprises, laterally disposed relative to each other, a middle part (4b); a first outer part (4a) connected to a first section (10) of the table (2) and slidable relative to the middle part (4b), a second outer part (4c) connected to a second section (12) of the table (2) and slidable relative to the middle part (4b), wherein the middle part (4b), the first outer part (4a), and the second outer part (4c) of the extension rail (4) each comprises an identically designed profile (106).

Abstract: A table sliding system comprising: a table surface (110) and a frame (120), wherein the table surface (110) and the frame (120) together form a sliding system (100) comprising a sliding surface (140) and at least one sliding member (150); wherein said at least one sliding member (150) is arranged to be movable along said sliding surface (140), to provide a relative movement between said table surface (110) and said frame (120).

Abstract: A method for detecting a faulty cooling unit in a set of cooling units configured to provide a coolant to work rolls arranged to process a work item therebetween, the method including: varying the flow rates of the coolant ejected from a sub-set of the cooling units; in response to varying the flow rates, determining a flatness variation value of the work item for at least each of the cooling units in the sub-set of cooling units, the flatness variation value being indicative of the work item flatness variation downstream of the work rolls; and detecting a faulty cooling unit based on comparing the flatness variation values to a reference flatness variation value.

Abstract: A method of controlling flatness of a strip of rolled material in a production line including a hot rolling mill and at least one cold rolling mill, downstream of the hot rolling mill, the method including determining flatness data of the strip in one or more of the at least one cold rolling mill and/or following passing of the strip through one or more of the at least one cold rolling mill; determining a thickness profile target of the strip for the hot rolling mill based on the flatness data; and passing the strip through the hot rolling mill and adjusting the thickness of the strip based on the thickness profile target. A control system and a production line are also provided.

Abstract: A valve drive device for actuating valves of an internal combustion engine a rocker arm device and a switchover device that includes at least two actuators for the at least one rocker arm device. The two actuators respectively include a switching element adjustable between a first position and a second position; a resetting device for resetting the switching element with a resetting force into the second position; a holding coil for offsetting the resetting force of the resetting device; a switching coil that counteracts the resetting force during operation. The switching coil and the holding coil adjust the switching element into the first position.

Abstract: A camera housing capable of carrying camera components and peripherals is provided. The housing includes a front portion, a back portion and an intermediate portion in between. The intermediate portion is formed with an arched recess dimensioned to receive the shoulder of an operator. A straight base line A extends substantially horizontally and defines a top section of the recess in an operating position of the camera housing. The front portion and the back portion substantially are located below line A.
