The inflatable hood (1) is provided with a plurality of inflatable, tubular support elements (3) with plastic films (2) arranged between them, which tenter one or more surfaces between the support elements (3) in the inflated state.

Abstract: A radio frequency detection system is provided that includes at least two radio frequency detection devices, which have an antenna each with a detection range for a radio frequency identification and detect the radio frequency identification information provided in the detection range. The radio frequency detection system is designed to attenuate a detection range of a detecting radio frequency detection device in the detection range of the at least one other radio frequency detection device by means of a compensation member such that the radio frequency identification cannot be detected by the detecting radio frequency detection device in the detection area of the at least one other radio frequency detection device.

Abstract: There is described a gas laser comprising a pair of substantially mutually parallel and opposed electrodes (17, 37), between which a volume is defined containing a gas in which said electrodes generate a discharge. At opposed ends of the electrodes, in said volume, mirrors (65) are arranged to define a resonant cavity. The electrodes form an integral part of two portions (5, 7) of a sealed housing (1), containing the gas and in which the mirrors and the electrodes are housed. The two portions (5, 7) forming the housing are electrically connected.

Abstract: A method is provided for producing a bearing ring (1) for large-size rolling bearings including at least one track (3) that is provided with a hardened peripheral layer. With the method the peripheral layer that is to be hardened is exposed to the electric field of an inductor in order to be heated and is then quenched. At least two inductors (2) are disposed above a common zone (a) of the annular track (3) that is to be hardened at the beginning of the hardening process. These inductors (2) heat the opposite peripheral layer to a hardening temperature at this location. The inductors (2) are moved in the opposite direction along the annular track in order to heat the adjacent central zones (b). Sprinklers (5) that are directed onto the heated peripheral layers are turned on following a short distance, and the peripheral layers are quenched starting from the center of the zone (a) that was heated at the beginning.

Abstract: A pneumatic linear gripper, including a gripper body (11) with a chamber (15), a piston (12) moving alternately in the chamber (15) and a pair of jaws (13) sliding associated and movable in opposite directions with piston via a translation device (20). The gripper body (11) is formed of two elements (14), or semi-shells, joined face to face to define at the same time the chamber (15) for the piston (12) and the sliding guides (16) for the jaws (13). The piston (12) is composed of a first component (21), made of a plastic material, bearing seals and a second component (22), made of metal, associated with the first and united, in particular integral, with the translation device (20) of the jaws in opposite directions.

Abstract: An improved construction of filtration media of a wedge filter provides a performance on both surface and inner filtration mechanisms with offering many times recycled use by washable functions. Particularly a wedge filter plate is used to construct a hollow cylindrical type media of wedge filter.

Abstract: A modular support (7) with holes (10) for attachment screws is equipped with a through seat (7A) with axial stop (7B) for a nut (9) capable of being received and engaged in said through seat; the modular support (7) can be utilized simply by preparing—on the load bearing structure—the threaded holes for the screws and a trace for a transverse spline, partly received in another trace (16) in the support (7).

Abstract: A plurality linkages, preferably a robot holding either a spot welder with welding guns or the workpiece. The plurality of linkages move a spot welder with open tongs toward a first spot weld position. The welding guns are then closed on the workpiece and welding is performed at the first spot weld position. While the welding is being performed, parts of the plurality of linkages are advanced toward a second weld position while the welding guns remained closed at the first spot weld position. When the welding at the first position is finished, parts of the linkages are already advanced towards the second position, and the remaining linkages are then advanced to the second position. This allows the linkages or robot to move faster from one spot weld position to another.

Abstract: A method is provided for determining faults during the operation of a pump unit. At least two electric variables that determine the electric output of the motor and at least one fluctuating hydraulic variable of the pump are detected. The detected values or values formed from these variables by algorithms are automatically compared to predefined stored values using electronic data processing and the results of this comparison are used to determine whether or not faults have occurred.

Abstract: The mowing head (1) comprises: a body (3), which can be engaged to a motor shaft and defines a peripheral edge (3C); at least one member for anchorage (9) of a cutting line (F), with an elastically loaded eccentric oscillating element, which co-operates with a surface of contrast fixed to the body for anchoring said cutting line. The oscillating element (11) projects from the peripheral edge of the body of the mowing head with a knurled edge (11Z), which forms a gripping surface for causing oscillation of the oscillating element and release of the cutting line.
