    摘要： Optical fiber is provided with a periodically reversing spin while the fiber is pulled through a melt zone. A cooled region of the fiber downstream from the melt zone passes between a pair of opposed elements. The opposed elements are moved so that surface regions engaging the fiber move in opposite lateral directions relative to one another, thus spinning the fiber about its axis. The lateral movement of the engaged surface portions is periodically reversed to reverse the spin direction. The opposed elements may include belts or rollers, which can be tilted to orientations oblique to the longitudinal direction of the fiber.

    摘要： The invention comprises a novel oil distributing arrangement, employing a valve which has a plurality of responses, for use in a gas compressing system or the like. The valve has a plurality of ports for admitting oil thereinto from an oil pump via a cooler, and for discharging oil therefrom, to a gas compressor (or some such similar oil-using end item) or for by-passing oil directly back to the oil pump (or a pump-serving oil reservoir), or for by-passing the cooler, etc. A translating valving element opens and closes communication between different oil admittance and oil discharge ports in the valve, in response to discrete ranges of valve-operating fluid pressures addressed to the valving element, to effect the cited by-passing functions, and to maintain a fairly uniform pump output pressure level.

    摘要： A burner manifold apparatus (10) for delivering reactants to a combustion site of a chemical vapor deposition process includes fluid inlets (32a, 32b), fluid outlets (49), and a plurality of fluid passages (50) extending therebetween. The fluid passages (50) converge toward each other from the fluid inlets to the fluid outlets. One embodiment includes a manifold base (12), a pressure plate (14), and a manifold burner mount (16) for mounting thereto a micromachined burner (58). The fluid passages (50) internal to the manifold base are configured to distribute symmetrically the fluid to the manifold burner mount. The fluid is then channeled through fluid passages in the manifold burner mount. The fluid passages converge, yet remain fluidly isolated from each other, and the fluid passages create a linear array for producing linear streams of fluid. Alternatively, the burner manifold apparatus may include a plurality of manifold elements in a stacked arrangement. In this alternative embodiment, the manifold elements are configured to produce a linear array of fluid passages at the top of the stack, increasing the number of fluid passages at each level of the stack closer to the top. As yet a further alternative, the burner manifold may be produced by extruding a particulate composite through a die to produce a manifold having fluid passages therein. This extruded manifold generally has a tapered section to which a burner may be mounted.

    摘要： A liquid cooling method and apparatus for rapid cooling of a hot glass fiber. In FIG. 1, an open ended liquid coolant container (12) is provided at its lower end with an inverted funnel surface (34). A vertically running, hot glass fiber (42) of indefinite length is continuously drawn through the container, as the container continuously receives a coolant liquid at its upper open end (30). The liquid continuously drains from the container lower open end (32) by flowing along flow surface (36) of the inverted funnel (34), downwardly and away from the glass fiber (42). The temperature of the fiber relative to the temperature of the coolant liquid is such that a vapor barrier surrounding the hot fiber is formed due to boiling of the liquid in a zone surrounding the fiber. This vapor zone facilitates diversion of the liquid (change in direction of flow) from the vertical to an angle thereto, along the inverted funnel surface. The substantially cooled hot glass fiber passes out of the container lower end for further processing, such as coating the fiber. The method and apparatus yields cooled glass fiber not wetted by the coolant liquid.
