  • Pleated Filter Preparation System
    Publication number: 20230278308
    Abstract: A pleated filter preparation system is provided for accurately counting pleats along a continuous sheet of pleated filter material and cutting the sheet into filter strips to be formed into filters. The pleated filter preparation system includes a pleat driver having multiple drive gears that engage with the pleats of the pleated filter material to move the pleated filter material through the system. A pleat counter counts peaks and valleys of each pleat comprising the pleated filter material so as to identify a target pleat to be cut. The pleat counter clamps and stretches the target pleat to distinguish the target pleat among the other pleats. A punch cut station cuts the target pleat to form a filter strip having a desired number of pleats. A pleat compressor compresses the filter strips to a predetermined size and then ejects the filter strips into a suitable container or bin.

  • On-car brake lathe adjustable hub adapter
    Patent number: 11745271
    Abstract: An adjustable hub adapter for coupling an on-car brake lathe to a wheel hub. An annular support frame coaxially carries an axially bored and threaded central mounting hub with a set of equidistantly spaced spokes. A lug bolt receiver is associated with each spoke, and consists of a receiving tube, a lever arm pivotally coupled to the spoke at a pivot bolt in proximity to the annular support frame. An engagement pin on each lever arm is captured within a synchronizing ring carried on the annular support frame. The rotational movement of any lug bolt receiver about an axis of the pivot bolt imparts rotational movement to the synchronizing ring, and in turn, causes each remaining bolt receiver to rotate about an associated pivot bolt axis, maintaining the lug bolt receivers in a synchronized and symmetric radial displacement from the central mounting hub.

  • Reverse flow reactors with selective flue gas cascade
    Patent number: 11746011
    Abstract: Systems and methods are provided for improving the operation of groups of reverse flow reactors by operating reactors in a regeneration portion of the reaction cycle to have improved flue gas management. The flue gas from reactor(s) at a later portion of the regeneration step can be selectively used for recycle back to the reactors as a diluent/heat transport fluid. The flue gas from a reactor earlier in a regeneration step can be preferentially used as the gas vented from the system to maintain the desired volume of gas within the system. This results in preferential use of higher temperature flue gas for recycle and lower temperature flue gas for venting from the system. This improved use of flue gas within a reaction system including reverse flow reactors can allow for improved reaction performance while reducing or minimizing heat losses during the regeneration portion of the reaction cycle.
