  • Patent number: 8596932
    Abstract: Provided herein are systems and methods for use in controlling a translocation process of a pneumatic tube system in order to reduce the amount of energy transferred from the tube system to a pneumatic carrier and, hence, its contents. Generally, these utilities entail identifying and/or reducing forces applied to a pneumatic carrier traveling through a travel path within a pneumatic tube system. The systems and method disposed herein allow for varying the velocity of a pneumatic carrier as it passes through a travel path of the pneumatic system. Such varying of the velocity allows for reducing the total forces applied to the pneumatic carrier during passage through the system. In one arrangement, the power output of a power source connected to a compressor device is altered to vary the velocity of pneumatic carries in the system.

    Abstract: Methods, apparatus, and systems for analyzing the motility of motile cells, such as neutrophils, are described. The microfluidic devices described herein generally include a main channel and one or more side channels and can be used for causing migration of cells in response to a biochemical gradient. The main channel has an inlet and an outlet and can be sized to receive the cells. The side channels that branch from the main channel terminate in a closed end and are sized such that the cell migrates into and through the side channel in response to a concentration gradient established between the main channel and the interior of the side channels in which the biochemical stimulus is trapped after priming and loading.

  • Publication number: 20120201613
    Abstract: A method for transferring objects (e.g. ophthalmic or contact lenses) between two consecutive processing stations, e.g. processing stations having differing cycle times or cycle speeds, including removing the objects from a preceding processing station, in which objects are advanced with a first cycle speed, transporting the objects to a subsequent processing station including a plurality of consecutively arranged receptacles (1-10), which are advanced through the subsequent processing station with a second cycle speed faster than the first cycle speed. The objects may be transported via at least one feed tube (12, 13) ending in a respective transfer nozzle (14, 15) arranged in vicinity of a corresponding one of the receptacles (1-10) and which is aligned with an inlet of the receptacle (4, 5; 4, 6). The respective transfer nozzles (14, 15) can be moved synchronously with and in the direction of advancement of corresponding receptacle.

  • Patent number: 8167517
    Abstract: A pump for particulate material includes a pump chamber wherein material flows into the pump chamber under negative pressure and flows out of the pump chamber under positive pressure. A plurality of pinch valves are provided to control flow of material into and out of the pump chamber. The pinch valves are operated independent of each other and of the pump cycle rate. A modular design of the pump is provided. A pump control feature is provided for air flow rate control during positive and negative pressure conditions.

  • Publication number: 20120051849
    Abstract: Provided herein is a system and method for alleviating gridlock in a pneumatic tube system. In various instances where inter-zone transactions conflict, one of the transactions is removed from a conflicting set and temporarily delivered to an alternate location in the system. This allows other blocked transactions to proceed. Once the gridlock condition is alleviated, the temporarily delivered carrier is retrieved and rerouted to its intended destination.

  • Patent number: 8123868
    Abstract: A method and apparatus for cleaning, drying, coating, baking etching and deposition of surfaces on glass substrate as it transitions thru and between small gaps between hydro-static porous media bearings. Due to the non-contact nature of the device extremely high pressures can be induced upon the work piece through various fluids without damage to the substrate, allowing the system to utilize the viscous nature of fluids to accomplish the desired cleaning, drying, coating, etching or baking. The process also allows for simultaneous and immediately sequential ordering of processes.

  • Patent number: 8113745
    Abstract: A pressure tank having a simple structure to intermittently feed powder to a conveying pipe, and a method for determining the intervals for feeding the powder to the conveying pipe. The pressure tank includes a tank body used as a structure of a pressure vessel having a receiving port at its upper portion and a discharging port at its lower portion, a first check valve disposed just under the receiving port so that it can freely move up and down, and so that it can close the receiving port by its upward movement that is caused by means of compressed air, and a second check valve disposed just under the discharging port so that it can freely move up and down, and so that it can close the discharging port by its upward movement that is caused by means of compressed air.
