Abstract: Advance shipment data associated with a shipment is received at an inventory controller device. The advance shipment data is verified. A data collection model is generated based upon the advance shipment data. The generated data collection model is stored within a memory. The shipment is autonomously validated by the inventory controller device using the generated data collection model in response to receipt of the shipment. An indication of a target storage location within a receiving facility is generated for each container of the validated shipment using a defined location topology model of the receiving facility including available storage locations.

Abstract: The invention relates to systems and methods for delivering controlled doses of a liquid cryogen. Controlling a restriction in a return conduit and other system geometry maintains proper circulation through a delivery and return conduit, enabling reliable control over the temperature and pressure of the liquid cryogen at the site of dosing.

Abstract: This invention provides an improved method for employing a plasma-arc cutting torch to cut a metal plate. The improvement consists in operating the torch with its lower portion submerged in a layer of water provided over the workpiece. In order to allow automatic adjustment of the torch to the appropriate working height above the workpiece, a mechanism is provided for mounting the torch with respect to the support carriage which guides its horizontal path. This mounting mechanism is such as to allow relative up and down movement between the torch and the support carriage and includes a detecting mechanism including a frame and vertical slides on which the cutting torch is secured so that when the mounting mechanism is lowered to the point where the torch touches the metal plate, the detecting mechanism communicates a signal for the upward movement of the mounting mechanism thereby raising the torch to a predetermined cutting distance from the metal plate.

Abstract: A process for plating beryllium copper with an excellent electrically conductive material such as gold for use in high reliability applications wherein a heat treating step is employed after forming to yield a desired hardness spring temper comprising the steps of: providing a copper-rich surface on the beryllium copper; electroplating the copper-rich surface with a diffusion barrier preplate; heat treating the beryllium copper material to a desired temper; and electroplating the material with a high electrically conductive material. This process provides for a void-free, durable gold plate which can be produced by a continuous automated strip plating line before and after heat treating.
