Abstract: An apparatus for making an article of footwear is provided. The apparatus may include a last shaped to resemble a human foot and being formed at least in part from a susceptor material that is thermally reactive to an electromagnetic field. The apparatus may also include an induction coil disposed proximate to the last and configured to produce an electromagnetic field that causes the susceptor material in the last to increase in temperature by induction heating.

Abstract: A last for forming an upper of an article of footwear includes an exterior surface, where the exterior surface includes a plurality of three dimensional structural surface components disposed over at least 50% of the exterior surface of the last.

Abstract: A vapor plate for covering a manhole of a cargo transport tanker includes a plate member and one or more push rod assemblies. Each push rod assembly includes a guide tube extending through the plate member and a push rod extending through the guide member. A rod of the push rod moves linearly and rotationally within the guide tube. An adjustable collar of a resistance mechanism may be fixed to the rod so that the collar engages a spring allowing a user to generate a resistive clamping force by pushing downward on the push rod. A user may clamp the rim of a manhole between a lower handle of the push rod and the plate member with the resistive force by positioning the lower handle underneath the rim after generating the resistance force. The push rod assembly is sealed to prevent vapor leakage.
