摘要： Rifling for the barrel of a firearm includes a first gain twist region for increasing the rotational velocity of a bullet as it travels from the breech towards the muzzle end of the barrel, and a second region in which the rifling is of a constant twist so that the bullet exits the muzzle end of the barrel at a constant rotational velocity. The bore defined in the barrel is tapered in a direction from the breech end to the muzzle end so that the diameter of the muzzle opening of the barrel is less than the diameter of the breech opening. The angle of the rifling is variable with the rate of the gain twist of the rifling. The gain twist of the rifling in the barrel is formed by a button, preferably having a sinusoidal shaped periphery, which is pulled through the barrel during the manufacturing process. The smooth periphery of the button prevents shredding of the barrel when the button is twisted at different speeds to provide the variable gain twist of the rifling in different sections of the barrel. In a further aspect of the invention, an apparatus is provided for selectively varying the rotational speed of the button to form the desired gain twist of the rifling during manufacture of the barrel.

摘要： By providing a fluid transfer assembly, two components forming bone cement are maintained separately from each other until actual intermixing thereof for use is desired, with the liquid monomer component being completely dispensed from a sealed unit directly into the mixing vessel in a closed loop manner, without exposure thereof to the user and without breakage of the container holding the liquid monomer, and a unique, multi-component, product handling and delivering system is achieved. In accordance with the present invention, the fluid transfer assembly is constructed for cooperating with the sealed vial or tube containing the liquid monomer and the mixing vessel for completely extracting all of the liquid monomer from the vial/tube in a closed loop operation and directly delivering the liquid monomer into the mixing vessel containing the dry powder. This transfer operation is achieved upon demand by the user, while preventing the liquid monomer from being exposed to the user or to the surrounding area.

摘要： Apparatus, systems and methods are provided for a planetary suit audio system that allows a suited occupant to acoustically interact, using three dimensional surround sound and directional accuracy, with and within the ambient surface environment. This is being developed directly for integration into future versions of a Martian surface suit. The hardware and apparatus incorporates a system that requires a low power suit interface, an intelligent digital signal processing (DSP) sound chip, appropriately integrated and tested sound processing Head-Related Transfer Function (HRTF) algorithms, integrated communications system circuitry, miniaturized electric eternal microphone arrays and speakers, and occupant used internal suit speakers or headsets. It has been found that the pressure at the Martian surface (equivalent to 99,000 feet in altitude on the Earth) supports the appropriate acoustical properties to allow for standard environmental auditory interaction. Exploration of the surface of Mars will require crews to routinely work within the confined spaces of environmental pressure suits during missions lasting as much a 500 days. The use of traditional suits means that operators have to adapt to an internal environment that limits the amount of direct sensory interaction with the external environment. Incorporating external audio capabilities has a major impact of providing the extravehicular activity (EVA) or surface operations crewmember with a second natural means of interacting with, and exploring their environment. This will also make the operating environment more tangible and comfortable for daily operations. Given this apparatus, crews will have the ability to judge actions, environmental conditions, and equipment operations based on auditory inputs, thus promoting increased operational safety and mission success.

摘要： Lower and upper covers permanently secured together form a vial enclosing chamber in a cap assembly which encloses the top of a bone cement mixing apparatus mixing chamber having prepackaged premeasured bone cement powder. The vial contains a monomer bone cement liquid and may be glass. The vial has two valve seats in corresponding ports on opposing vial side walls sealed by a releaseably secured preferably glass valve member threaded to a nozzle attached to the cap assembly. The vial ports are aligned with a mixing chamber liquid inlet port to permit the cement liquid to flow into the mixing chamber from the opened valves. The vial may be supplied enclosed in a separate package and includes valves on a valve stem attached to the package for opening and sealing the vial. In the alternative, the vial is frangible glass and may be opened by fracturing it and retaining the fragments in the vial receiving chamber to release the liquid to the mixing chamber.
