Abstract: A viscometer assembly includes a first plate with a rail configured to constrain fluid thereon between its edges by surface tension. A second opposing plate has a surface spaced from the rail by a predefined gap of constraining fluid to the rail by surface tension when the rail is inclined and gravity pulls the fluid along the rail. The kinematic viscosity of the fluid is determined as a function of the predetermined gap and the time it takes the fluid to flow along the rail.

Abstract: A method of manufacturing a composite turbine rotor in which blade coupons are fabricated from flat braided fabrics that have extending axial fibers. The extending axial fibers are then woven between the plies of polar woven fabric which make up the body of the rotor. This preform assembly is then impregnated with resin and cured. The blade coupons make up the blades of the rotor and can be made to have an airfoil shape, a curved shape, or a twisted shape by the use of blade formation tools designed for forming the rotor preform.

Abstract: The invention is a sharpener for a knife of a food slicer. The sharpener includes a base assembly and a sharpener assembly. The base assembly includes a lever mounted thereto on a pivot; the lever carrying a cam member which extends therefrom. The sharpener assembly includes a housing and a longitudinal cavity, a sharpening wheel mounted for rotation on an axle which reciprocates lengthwise in the cavity, a compression spring positioned in the cavity at the base of the axle, and an actuator which reciprocates in the cavity portion on the side of the spring opposite the axle. Upon moving the lever about its pivot, the cam contacts the actuator and moves the actuator in the direction of the axle and compresses the spring. The spring moves the plunger lengthwise within the cavity and urges the sharpening wheel against the knife.
