Abstract: Method and apparatus are illustrated for enhancing the air flow characteristics in an air jet loom reed having a tunnel wherein the reed is removed from the loom and positioned in a frame for utilizing a rolling contact by a carriage which conveys measuring apparatus and buffing devices along a predetermined path at a desired sequence and speed of operation.

Abstract: Improved apparatus for the transportation of granular materials such as concrete is disclosed. The apparatus includes a pneumatic discharge area, a rotatable feed wheel having a plurality of pockets opening to a hopper for transporting increments of material to the discharge area and vibrating apparatus including one or more resilient members disposed adjacent the openings to the feed wheel pockets for being alternately flexed and released to impart vibration to the resilient members to enhance the flow of material into the pockets. The vibrating apparatus further includes a mounting ring, adapted for mounting in the device, and one or more inwardly extending mounting bars affixed to the ring for carrying the resilient members.
