A method of making a shell (30) of a lightweight composite propulsor blade (10) of spar and shell construction having a leading edge portion (39) having twice the thickness as the remainder (33, 35, 37) of the shell thereby enhancing resistance to foreign object damage and improving erosion resistance.
摘要:
A piston ring compressor for compressing a piston ring about a circumference of a piston so that the piston can be inserted into a cylinder. The piston ring compressor includes a wall forming a hollow shaped member and an inner compression surface formed about the interior portion of the hollow shaped member. The inner compression surface has a diameter which gradually decreases from a second end to a first end. The piston ring compressor applies an even compressive force about the piston ring as the piston ring and piston are slid through the piston ring compressor from the second end to the first end.

A stator core module assembly (20) is provided which is adapted to be mounted to at least one structural element (16, 18) coupled to a stator frame (10). The stator core module assembly comprises a stator core module (22) adapted to form part of a stator core (21) and at least one keybar (32A, 32B) having a length less than a width of the stator core. The keybar may be coupled to the stator core module. The stator core module assembly further comprises at least one attachment member (34) for coupling the keybar to the structural element coupled to the stator frame.
摘要:
A piston insertion machine for inserting piston assemblies into respective cylinders of an internal combustion engine. The piston insertion machine eliminates the need for individually lifting and inserting the piston assemblies into the respective cylinders. The piston insertion machine includes a barrel assembly for holding the piston assembly. A first set of components pivot the piston barrel assembly (and thus the piston assembly) from an upright position to a horizontal position. Another component inserts the piston assembly into the cylinder of the engine block.

A piston ring compressor having position sensors for aligning a piston assembly with a cylinder of an engine block. The position sensors enable a piston assembly to be properly aligned with the cylinder prior to inserting the piston assembly into the cylinder without damaging either the piston assembly or the cylinder. The position sensors are linear variable distance transducer which are used to align the centerline of the piston ring compressor with the centerline of the cylinder.
摘要:
A method for wireless synchronization of a first and second magnetic electronic article surveillance (EAS) systems arranged for operation in close proximity to one another. The method includes the steps of programming each of the first and second EAS systems for transmitting at least one unique signal into a partially overlapping interrogation zone of the EAS systems and for receiving any signals from the interrogation zones at respective and predetermined transmit and receive phases relative to a common reference. The first EAS system transmits at least one unique signal containing phase information which is received and identified at the second EAS system during one of its receiver phases as the one unique signal. The second EAS system uses the conveyed phase information received to transmit synchronously with transmissions from the first EAS system.
摘要:
Systems and methods for detecting a security tag. The methods comprise: detecting motion of the security tag while in use to protect an article from unauthorized removal from a protected area; and emitting a first waveform from a radiating device of the security tag in response to the motion's detection. The first waveform is detectable by an Electronic Article Surveillance (“EAS”) monitoring system. The radiating device comprises a device other than an EAS element, a Radio Frequency Identification (“RFID”) device and a Near Field Communication (“NFC”) enabled device.

The present invention comprises a method and apparatus for installing a stator core, or portions thereof, into a power generator frame 2 that comprises assembling the stator core inside of a container 60, and then moving the container to the power generator 1. The container 60 is horizontally aligned with the power generator 1, and the stator core is transferred from the container to the power generator.
