Abstract: A dispensing port adapter device for preventing a loss of pellets from a feed tube to a suction tube includes a sleeve extending from a first end to a second end. A chamber space is defined within the sleeve and the second end receives the feed tube of the railway car hopper into the chamber space of the sleeve. An end wall is attached to the sleeve and covers the first end. The end wall has an aperture extending therethrough to receive the suction tube. A securing member is mounted on the sleeve and secures the sleeve to the feed tube wherein an outlet of the feed tube is positioned within the chamber space. A seal is attached to the end wall and covers the aperture to prevent the pellets from exiting the sleeve through the aperture.

Abstract: Device and method for handling biological specimens. For example, the device includes a base and a substrate. The substrate includes a first surface disposed on the base and a second surface configured to support a biological specimen. A compressive element is disposed on the second surface of the substrate and surrounds the biological specimen. The compressive element includes an opening opposite the second surface of the substrate on which the compressive element is placed. The opening is configured to form a well that allows one or more reagents to be introduced into the well for chemically processing the biological specimen. The compressive element and the base cooperate to secure the compressive element to the substrate to form a seal which is configured to retain the one or more reagents in the well.

Abstract: Method and system for processing biological specimens. For example, the method includes loading a plurality of biological specimens on a continuous substrate at a plurality of spaced-apart locations on the continuous substrate, attaching a plurality of wells to the continuous tape substrate corresponding to the plurality of spaced-apart locations where each well surrounds a respective biological specimen on the continuous substrate, performing one or more chemical processes on the respective biological specimen contained in the each well of the plurality of wells, and analyzing results of the one or more chemical processes on the respective biological specimen contained in the each well of the plurality of wells.

Abstract: An internal combustion engine having one or more modules each employing fluidly-communicating, oscillating, power cylinder and air cylinder. The power and air cylinders oscillate about separate, individually supporting sets of trunnions positioned non-linearly with respect to each other and permitting the passage of air therethrough. The air cylinder includes a pre-combustion chamber for the purpose of withholding the delivery of a portion of compressed air to the power cylinder until all spent gases have been evacuated from the power cylinder. Means for enhancing fuel dispersion and/or vaporization is provided whereby cavities are provided in the cap of both the air cylinder and the power cylinder that are in selective synchronous fluid communication.

Abstract: A disposable lighter has an elongated body and an L-shaped clip that has a dual purpose of actuating a release valve for gaseous fuel and securing the lighter within a user's pocket. Simplicity in design renders the device easy to manufacture, reliable in performance, and disposable after exhaustion of the fuel supply.
