    Abstract: A heater includes a conduit and three insulated electrical conductors located in the conduit. At least one of the three insulated conductors includes an electrical conductor at least partially surrounded by an insulation layer and an electrically conductive sheath at least partially surrounding the insulation layer. One or more layers of electrical insulation at least partially surround the three insulated electrical conductors in the conduit. The one or more layers of electrical insulation electrically isolate the insulated electrical conductors from the conduit.

    Abstract: An LCD projector includes: a light source assembly for supplying light source required for the LCD projector; an image generating mechanism for generating image to be projected, having an LCD panel; a projection objective lens assembly for projecting the image generated by the image generating mechanism onto a screen; and a cooling mechanism for cooling off the surface of the LCD panel of which the temperature is raised due to the radiation of the light source. A thermal diffusion film having good transparency and thermal diffusivity is attachd to the surface of the LCD panel on the one side nearer to the light source assembly so as to facilitate homogeneous thermal diffusion in the surface of the LCD panel, and thus prevent deterioration of quality of projected image due to thermal shimmering caused by cooling air flow coming from the cooling mechanism.

    Abstract: A sliding needle bar tufting machine is provided with two needle bars each carrying a single row of needles, at least one needle bar being mounted to be adjustable in a warpwise direction relative to the other needle bar to enable the spacing between the two rows of needles to be varied. In an alternative construction a needle bar is arranged at each side of a needle bar carrier and both needle bars are adjustable along a common support member mounted in the carrier.
