Abstract: A safety latch for supporting a post in a post driver while the post is being driven into the ground. A post-engaging roller is mounted on a lever arm that is pivotally attached to the post driver and moveable between a released position for positioning of a post in the post driver and a working position where the roller is in supporting engagement with the post. A spring biases the roller to maintain supporting engagement with the post while it is driven. In a preferred embodiment, the spring is part of an over-center device for biasing the safety latch to both the released and working positions depending on which side of center the lever arm is positioned.

Abstract: A laminate structure or label for mounting on a surface of a tire, for example, a label or RFID tag label, includes a face stock layer of a material permeable to the migratory oils and waxes present in tire rubber. The permeable material allows the oils and waxes to pass through the face stock and prevents their build up between the face stock and the adhesive layer, improving the adherence and durability of adherence of the laminate structure to tire rubber.
