Appl. No.:

5/544654

Inventors:

Robert V. McCarthy - Columbia PA

Assignee:

Armstrong Cork Company - Lancaster PA

International Classification:

G01N 1110

US Classification:

73 60

Abstract:

A coaxial cylinder rheometer having a very small (less than 0. 020 inches [0. 0508 cm]) gap between the concentric cylinders and being capable of charging highly viscous (greater than 100,000 poise) and/or thermally sensitive materials, e. g. , Polyvinyl Chloride, Polyurethane, etc. , into this gap for testing. The inner cylinder, rotor, comprises a single element which can be driven axially and rotationally. The outer cylinder, stator, comprises an upper part having a projection-like ring on its lower surface and a lower part having a trough-like ring in its upper surface. The two parts are fastened together with mating screw threads on each part. The material to be tested is deposited in the trough-like ring in the lower part and the two parts are screwed together into an operational position wherein simultaneously the projection-like ring moves into the trough-like ring extruding the flowable material therebetween into the gap between the coaxial cylinders and the bottom and top edges of the inner surfaces of the upper and lower parts, respectively, come together to form a complete and uninterrupted outer cylinder inner surface.

Abstract:

A bar connector comprises an elongate bar with a series of electrical attachment structures along a length of the elongate bar. Each wire electrical attachment structure is to secure at least one wire to the elongate bar. A flexible connector wire with two ends that connect to the elongate bar is used to establish an electrical connection between the at least one wire and a secondary distribution line by a crimp connector. A method of connecting an electrical wire with the bar connector is also claimed.
