Abstract: A method of manufacturing a shell of a wind turbine blade is disclosed. The method of manufacturing includes laying one or more layers of fiber on a surface of mould to form the shell. A spar element is positioned at a pre-defined position on the one or more layers of fiber, and a vacuum bag is positioned or covered around the one or more layers of fiber and the spar element. The method further includes step of infusion of resin through the one or more layers of fiber and the spar element. The resin is subsequently allowed to cure to obtain the shell of the wind turbine blade. The spar element is thus adhered to the shell through resin infusion process.

At least one of the plurality of bushings is provided in an aperture 76, 78 and on either ends of the locking pin 74. Further, at least one primary restraining mechanism 7 is configured in the at least one bushing 1 at one end of the locking pin 74, where the primary restraining mechanism 7 is fixedly connected to the at least one bushing 1 and is configured to restrain at least one of sliding and rotary movement of the locking pin 74.

Abstract: A radio frequency identification fob is disclosed which includes a body and a cover engaged with each other as a fob to enclose a radio frequency identification device. The body and the cover are typically molded plastic. The engagement of the cover to the body may be via an elongated alignment ridge coupled in slideable manner in an elongated mating groove substantially along the major axis of the body. The cover may be secured engaged with the cover by a fastener that could include a releasable latch engaged with a catch. The fob could further include an attachment device such as a key ring to couple the fob to other personal items.
