A labeling machine includes a base structure which rotatably supports a conveyance carousel for the containers to be labeled and at least one protection structure which can move, with respect to the base structure, from an active condition, in which it prevents access from the outside to at least one portion of the conveyance carousel, to an inactive condition, in which it allows access from the outside to the at least one portion of the conveyance carousel, and vice versa; the protection structure includes a supporting framework for components of the protection structure, which includes a profiled bar having an arc-like extension around the axis of the conveyance carousel, which is arranged above the base structure and forms at least one engagement seat for elements for fixing to the supporting framework at least one of the components.

A machine control and data logging station, intended for use with a saw or other machine tool, features a processor which monitors a number of input lines, a real time clock and time stamp function. Any change of input signals from the machine tool will be recorded in flash memory. Both wired and wireless outputs may read the memory at any given time. Optionally, hardware or software data communication encryption may be employed to provide increased confidentiality and security. The station continually monitors sensor inputs and can react automatically to emergency-stop the machine tool upon sensing a dangerous condition.

Safety systems requiring intentional function activation and material testing systems including safety systems requiring intentional function activation are disclosed. An example material testing system includes: an actuator configured to control an operator-accessible component of the material testing system; an operator interface comprising a plurality of inputs; and one or more processors configured to: control the actuator based on at least one of a material testing process or an input from the operator interface; and require two or more inputs to be received within a predetermined threshold time to permit at least one operation of the actuator.

A protective housing for a testing, measuring or production device has a protective element, which seals a housing opening and is held and guided by guide devices and can be moved into an open position by a drive device. The guide devices have arched sections which are outwardly curved forward and extend backwards in a straight line on an upper side of the protective housing. The protective element includes two flexurally stiff rectangular plates, which have straight longitudinal sides and a curve approximating the arched sections and are connected to each other on a longitudinal side via a hinge. The guide devices include a number of guide elements guided on a guide rail, wherein a respective guide element is arranged on the hinge and further guide elements are arranged on both sides of the hinge. The drive device drives the rearmost guide element via two traction transmissions, which have traction mechanisms running parallel to the straight section of the guide devices.

An enclosure for a laser in which on side of the enclosure includes a rotatable positioner and a vertically slidable door movable between open and closed positions. With the door in the open position, the positioner is free to rotate, thereby enabling an workstation to rotate into and out of the enclosure.

A protective cover having at least one supporting profile and having at least one length-adjustable protective cover element, the supporting profile having a first connecting means for detachably connecting the protective cover element, and the protective cover being movable in a direction of movement within a predetermined range of movement, which is defined between a first position of the protective cover and a second position of the protective cover, the supporting profile being rotatably mounted around an axis in such a manner that the height of the cross section of the supporting profile is disposed essentially perpendicular to the direction of movement in the first position and parallel to the direction of movement in the second position.

A method for determining and/or monitoring the state of a protective cover, includes the steps of a) obtaining a first state value of at least one characteristic physical, mechanical and/or chemical property of the protective cover at a first point in time; and b) obtaining a second state value of the at least one characteristic property of the protective cover at a second point in time, which is to subsequent to the first point in time; and c) comparing the obtained state values; and d) determining the state of the protective cover based on the comparison performed in step c).
