摘要:
A mass pod turbine device includes a rotating element configured to rotate about a shaft axis. A plurality of mass pods restrained about the periphery of the rotating element. The mass pods are restrained to the rotating element, but may be displaced relative to the center of rotation. During a rotational cycle of the rotating element, the mass center of each mass pod may be dynamically displaced relative to the center of rotation. The mass pods then generating a mass imbalance about the rotational axis and causing the device to rotate about the shaft axis. The system also provides a useful variable inertia member for the storing of the kinetic energy of a rotating assembly.

An apparatus for enabling a base station to transmit radio frequency signals with a transmit diversity technique comprises a first antenna implemented in the base station; and a second antenna implemented in the base station, and placed apart from the first antenna by a predetermined distance. The first antenna utilizes a first frequency band of a predetermined frequency spectrum for transmitting signals, and the second antenna utilizes a second frequency band of the predetermined frequency spectrum for transmitting signals. The first and second frequency bands do not overlap.

A system and method improves linearly-polarized microstrip patch antenna performance and fabrication through the incorporation of a pin fin ground plane and an integral antenna feed assembly. In one embodiment, a patch antenna system includes an antenna area with a patch antenna that provides radio communications. A heat dissipation member is coupled to the antenna area and includes a plurality of pins that provide for both the dissipation of heat from the antenna area and a ground plane for the antenna area. An antenna feed line is further coupled with the antenna patch for providing an electrical connection from the antenna patch to other electronic circuitries, such as a wireless device that may be mechanically coupled to the heat dissipation member. Heat generated during the operation of the wireless device is directed to ambient air by way of the heat dissipation member.

Air voids within a die casting may be minimized by controlling, during the shot process, the venting of gas from the shot tube through a shot tube opening with the proper size at a proper location, and the movement of metal within the shot tube to avoid entrapped gas and prematurely solidified aluminum particles in the molten metal being injected into the die cavity during the shot process.

The present invention tablet filler device system includes a plurality of individually secured cells with a tablet hopper and drum functionally adapted to regulate and orient gravity outflow of tablets, a gravity feed chute connected to and downstream from the hopper to singularly align and feed tablets, and a rotatable starwheel having slots to receive tablets from the feed chute to move tablets to a container filling substation. There is also a tablet inspection mechanism located on the feed chute to discern quality characteristics of tablets moving down the feed chute in accordance with a predetermined standard, and a tablet ejector to eject unacceptable tablets. A stepper drive motor with a counter capability for driving the starwheel in a step fashion for controlled release of tablets is included, and an optional counting verification sensor. The cells are interconnected for computer controlled automatic order filling for a variety of tablet types and container sizes.

A method of tying over an individual customer service connection from a live outer gas main to an inner gas main inserted within the liver outer gas main comprises defining a generally annular region within the space between the inner and outer mains. The region is upstream from the customer service connection between the customer service connection and the source of gas for the outer main. The sidewall of the outer main is opened intermediate the ends of the region, and an amount of a high-density liquid foaming composition sufficient to fill the region is introduced into the opening. The foaming composition is permitted to foam and harden to a plug in the region. Before the foaming composition is permitted to foam and harden, a first end of a first conduit is inserted into the opening, and pushed into the space so that the first end lies upstream from the region. A section of outer main downstream from the region is then removed and the new customer service connection is placed through the sidewall of the inner main exposed by cutting away the outer main.
摘要:
This invention relates to no-bake foundry binders and a no-bake process for preparing foundry shapes which utilizes polyurethane-forming foundry binders. The binders are unique because the isocyanate component preferably contains no solvent and the weight ratio of the phenolic resin component to isocyanate component is atypical. It has been found that the use of these binders in a no-bake process produces foundry shapes with improved tensile strengths.

A method for inserting a smaller cross sectional area, higher pressure fluid conduit or "main" into a larger cross sectional area, lower pressure fluid main, includes inserting a length of smaller diameter gas main into a length of larger diameter gas main while the larger diameter gas main remains pressurized with the gas. The method includes providing a parallel gas pathway from a section of larger diameter main upstream toward the gas supply from the length of larger diameter main into which the smaller diameter main is to be inserted.
