A method and machine for wrapping an article, whereby the article is fed through a feed station, where the article is applied with a respective sheet of wrapping material which is folded into an L about the article, so as to have a free edge not contacting the article, and through a follow-up wrapping station, where the sheet of wrapping material is folded about the article to form a tubular wrapping by applying the free edge onto the article; between the feed station and the wrapping station, the free edge of the L-folded sheet of wrapping material is subjected to traction in substantially the opposite direction to the travelling direction of the article by subjecting the first free edge to suction, so as to smooth the sheet of wrapping material onto the article.

The invention relates to a method and device for controlling the mass flow rate of a sonic gas stream in a pipe. To carry out the above operation, an electric discharge is applied inside the pipe so as to create a plasma in the pipe. The electric discharge allows for an increase in the temperature of the gas stream and thus a variation in the mass flow rate or the pressure of the gas stream. By periodically emitting the electric discharge, a pulsed or adjustable gas jet is obtained at the outlet of the device. The gas jet can then be used to control a main stream.

The embodiment of the invention provides a semiconductor device and a method of forming the same. A static random access memory (SRAM) cell includes a first gate and a second gate each extending in afirst direction. A first gap separates the first gate from the second gate in the first direction. The SRAM cell includes a Vcc contact extending in the first direction. A second gap separates the Vcccontact and the first gate in a second direction perpendicular to the first direction. No segment of the Vcc contact overlaps with the first gap in the first direction. The SRAM cell includes a Vss contact extending in the first direction. A third gap separates the Vss contact from the first gate in the second direction. A segment of the Vss contact is disposed to the first gap. The Vss contact is smaller than the Vcc contact in the second direction.

A butterfly valve comprising a valve seat, a butterfly body engaging the valve seat, a shaft on which the butterfly body is keyed, an electric actuator coupled to the shaft, a torsional return spring adapted to rotate the butterfly body towards a closed position, a compression abutment spring adapted to rotate the butterfly body towards an open position, and an abutment body which causes the action of the abutment spring to stop when the butterfly body is in a limp-home position; the abutment spring having a mechanically fixed end connected to the valve body and a mechanically moving end connected to a wheel rigid with the shaft by means of the interposition of a transmission member mounted to slide within a chamber housing the abutment spring.

According to an embodiment of the present invention there is provided an apparatus for controlling a sub-system of a wind turbine. The apparatus comprises a cooling system comprising first and second heat exchangers, and a fluid circuit arranged to enable a coolant to flow between the first and second heat exchangers; and a processor. The processor is configured to: monitor one or more operational parameters of the cooling system; determine an icing risk based on the one or more operational parameters; and generate a control signal for output to the wind turbine sub-system in dependence on the determined icing risk.

A turbine assembly with a hollow aerofoil having a main cavity with an impingement tube, insertable inside the main cavity for impingement cooling of an inner surface of the main cavity, and a platform at a radial end of the hollow aerofoil, and a cooling chamber for cooling the platform arranged relative to the hollow aerofoil on an opposed site of the platform. The cooling chamber is limited at a first radial end by a wall segment of the platform and at an opposed radial second end from a cover plate. The impingement tube extends in span wise direction through the cooling chamber from the platform to the cover plate and restricts a sub-cavity of the main cavity. The wall segment includes an entry aperture for a cooling medium to enter from the cooling chamber of the platform into the sub-cavity of the hollow aerofoil.
