Abstract: A process and apparatus are provided for the manufacture of a composite fibrous strand comprising glass fibers. Glass fibers and an additive fibrous material (e.g., thermoplastic polymeric fibers) are each introduced separately into a substantially rotationally symmetric zone that is closed circumferentially except for a longitudinal introduction locale. The glass fibers and the fibers of the additive fibrous material are subjected to a vortex to form a homogeneous composite fibrous strand. Good admixture of the fibrous components is made possible thereby facilitating the ultimate production of composite articles wherein the glass fibers are disposed as reinforcement in a highly uniform manner. Such homogeneity and uniformity provides improved mechanical properties to the end user.

Abstract: An apparatus for dispensing ice includes a bin and a shroud that contains a recess for housing a wheel. The shroud mounts to a front wall of the bin and includes a chute that communicates exterior to the bin. The shroud further includes a curved plate that directs ice into the recess so that the wheel can raise the ice to the chute. A plate mounts at an angle sloping downward towards the front wall of the bin to direct ice onto the curved plate of the shroud. A discharge chute assembly mounts to the ice bin and communicates with the chute of the shroud to permit the delivery of the ice exterior to the bin. A gear moor drives the wheel to facilitate the lifting of the ice to the chute of the shroud. Alternatively, in a combination ice and beverage dispenser, the plate mounted within the bin is replaced with a cold plate mounted within the bin at an angle sloping downward towards the front wall of the bin. The cold plate directs ice in the bin onto the curved plate of the shroud and communicates at inlets to a beverage source to cool beverages before dispensing. Dispensing valves communicate with outlets from the cold plate to permit the dispensing of beverages from the ice and beverage dispensing apparatus.

Abstract: At least one parameter of at least one fluid in a pipe (12) is measured using a spatial array of acoustic pressure sensors (14, 16, 18) placed at predetermined ax-ial locations x1,x2,x3 along the pipe (12).  The pressure sensors (14, 16, 18) provide acoustic pressure signals P1(t), P2(t), P3(t) on lines (20, 22, 24) which are provided to signal processing logic (60) which deter-mines the speed of sound a mix of the fluid (or mixture) in the pipe (12) using acoustic spatial array signal processing techniques with the direction of propagation of the acoustic signals along the longitudinal axis of the pipe (12). Numerous spatial array processing techniques may be employed to determined the speed of sound a mix. The speed of sound a mix is provided to logic (48) which calculates the percent compo-sition of the mixture, e.g., water fraction, or any other parameter of the mixture or fluid which is related to the sound speed a mix. The logic (60) may also determine the mach number (MX) of the fluid. The acoustic pressure signals P1(t), P2(t), P3(t) measured are lower frequency (and longer wavelength) signals than those used for ul-trasonic flow meters, and thus is more tol-erant to inhomogeneities in the flow. No external source is required and thus may operate using passive listening. The invention will work with arbitrary sensor spacing and with as few as two sensors if certain information is known about the acoustic properties of the system.

Abstract: A combustor of a gas turbine includes a combustion tube acting as a combustion chamber. In the combustion tube, a cylindrical heat insulating member is disposed and forms a wall of the combustion chamber. Numerous cooling air passages are formed in the heat insulating member and extending in the axial direction between cooling air inlet disposed at one end of the heat insulating member and cooling air outlet disposed at the other end of the heat insulating member. The heat insulating member is attached to the inner surface of the combustion tube at its cooling air inlet side end and a seal ring is disposed around the outer circumference of the heat insulating member at a portion between the cooling air inlet side end and the cooling air outlet side end. The seal ring is made of heat resistant material and prevents cooling air flowing through the annular space between the inner surface of the combustion tube and the outer surface of the heat insulating member.      Since cooling air flows through the annular space around the outer surface of the heat insulating member, all of cooling air flows through the cooling passages in the heat insulating member and is used for cooling the heat insulating member. Therefore, the cooling capacity of the heat insulating member increases.
