Abstract: A turbomachinery apparatus includes: a turbine, including: a turbine component defining an arcuate flowpath surface; an array of axial-flow turbine airfoils extending from the flowpath surface, the turbine airfoils defining spaces therebetween; and a plurality of fences extending from the flowpath surface, in the spaces between the turbine airfoils, each fence having opposed concave and convex sides extending between a leading edge and a trailing edge, wherein the fences have a nonzero camber and a constant thickness, are axially located near the leading edges of adjacent turbine airfoils, and wherein at least one of a chord dimension of the fences and a span dimension of the fences is less than the corresponding dimension of the turbine airfoils.

Abstract: An equipment for shredding various meats, cooked and/or pre-cooked, deboned, whether of ox, chicken or other animals, equipped with a meat striping system to shred it without crushing it, with simple and resistant structure, motorized and coupled directly to the motor shaft for productivity gain, and also, with components of modern and functional design, which provide efficiency and safety for the operator during handling. The present meat defroster is constituted by a rectangular-shaped bench (1), provided with four legs, with motor and shaft mounted horizontally.

Abstract: A method and apparatus for testing closed hydraulic systems such as a blowout preventer for leaks maintain a constant pressure in the portion of the hydraulic system to be tested. A variable displacement pump is connected to the system for maintaining a constant pressure within the system. Any amount of fluid introduced into or removed from the blowout preventer in order to maintain constant pressure is measured and is an indication of the leak rate in the closed hydraulic system.
