  • Publication number: 20120107211
    Abstract: A process for manufacturing high density boron carbide by pressureless sintering, enabling to create sintered products of complex shapes and high strength. The process comprises mixing raw boron carbide powder with carbon precursor, such as a polysaccharide, compacting the mixture to create an object of the desired shape, and finally carbonizing and sintering the object at higher temperatures.

  • Publication number: 20100294476
    Abstract: An automatic temperature regulating device for controlling the flow of a cooling gas through a conduit. The device consists of a plurality of flaps connected to the conduit and made of a shape memory alloy, whereby when in the austenite phase said flaps are in a relatively open state and when in the martensite phase said flaps are in a relatively closed state.

  • Publication number: 20100224267
    Abstract: A temperature responsive valve (TRV), for controlling a flow of gas, employing a shape memory alloy (SMA) wire. The SMA wire is forced by the flow of gas to elongate at temperatures not exceeding a limit known as the transition temperature lower than the austenitic transition temperature. The elongation at a temperature lower than the austenitic transition temperature may be extensive enough to cause a nozzle of the TRV to be blocked, preventing further passage of the gas.
