  • Patent number: 9987655
    Abstract: A fluid dispensing apparatus and method is disclosed. Systems include an in-line or linear bladder apparatus array configured to expand to collect a charge of fluid, and contract to assist with fluid delivery and dispensing. The bladder array is disposed within a chamber of pressure control fluid common to exterior surfaces of each bladder in the bladder array. Simultaneously, some bladders within the array of linear bladders can be dispensing fluid or maintaining fluid while some bladders are collecting fluid. A given filtration rate can be less than a dispense rate and thus the system herein compensates for filter-lag that often accompanies fluid filtering for microfabrication, while providing a generally linear configuration that reduces chances for defect creation. With multiple bladders, multiple different types of fluid can be readied for selective dispense.

  • Publication number: 20080311316
    Abstract: A device which simulates natural flowering actions, including growth and efflorescence, is actuated by partial immersion of a stem into a liquid. An aperture through the stem base admits the liquid into the stem. A piston slidably disposed within the stem is driven downwardly by the bias force of a resilient spring while an agent which impedes the piston motion dissolves in the liquid. Growth is simulated by a sleeve outside the stem which descends in relation thereto to push the flower upwardly. A simulated corolla is attached to the stem and gradually rotates and opens during the ascent thereof. A cam controls the pivotal position of lifters which open and close the corolla. The petals of the corolla vibrate before opening and open with variations in starting time. As the corolla opens, a surprise gift, gradually ascending on a presentation platform, is revealed. The device may be reused.
