PIN ASSEMBLY FOR CONVEYOR CHAIN.

摘要

A pin assembly (10) for a chain of a material handling system includes a pin element (12) and an attachment element (14). The pin element includes a shaft portion (16), a head portion (18) at an end of the shaft portion, and an attachment portion (24) at an end of the shaft portion opposite the head portion. The attachment element (14) is configured to attach to the attachment portion of the pin element, and is positionable at the attachment portion and is retainable thereto. The attachment element may comprise a second head portion (14) to define an I-type pin assembly or may comprise a side link and pusher member construction (114) or other element or member. A mounting extension (20) may extend from the attachment portion for mounting an object to the pin assembly after the attachment is attached to the pin element.

A mounting extension (20) may extend from the attachment portion for mounting an object to the pin assembly after the attachment is attached to the pin element. A wireless communication node, such as a repeater, including a frequency translating repeater, a physical layer (PHY) repeater, time divisional duplex repeater (TDD) and the like, is configured with a pair of directional patch antennae and an omnidirectional antenna. The patch antennae can be selected depending on the orientation of the repeater package to communicate with a station such as an access point or a base station. The omni-directional antenna can be directed toward another station such as a client. The patch antennae and the omni-directional antenna can be orthogonally polarized to increase isolation and reduce electromagnetic coupling. Multiple antennae can be used in multiple-input-multiple-output (MIMO) configurations.
