Abstract: A compaction unit (12) having a frame (14) resiliently mounted to a rigid support (10), the frame rigidly supporting a molding flask (24) therein, and having at least one pair of synchronized motors (A) with eccentric rotors coupled to the frame for vibratory motion therewith. The motor pairs are synchronized in counter rotation so that a given pair produces a net force vector perpendicular to a line joining the motor pair. Preferably, three motor pairs (A, B, C) for driving the frame in three different axes, are controlled by a program which permits sequential specification of the duration and net vector acceleration, over a wide range of values. The motors are maintained in synchronized phase relationship during the changeout of flasks, so that the compaction vectors experienced by each flask begin from the same initial idle condition.

Abstract: A circulating fluidized bed furnace (10) wherein a non-cyclonic particulate separator (18) is integrally disposed in the flue gas flow path between the furnace gas outlet (14) and the flue gas duct (16). The separator (18) comprises an arcuate duct (20) having a curvilinear inner wall (24), the portion thereof which is disposed across the inlet to the flue gas duct (16) having a plurality of openings (28) therein which provide a flow area through which a portion of the flue gas pass into the flue gas duct (16). Gas/solids separation is accomplished as the flue gas turns sharply from its arcuate path to pass through the openings (28) in the inner wall (24). The momentum of the particulate solids and the centrifugal forces acting thereon prevent the solids from sharply turning and cause the solids to continue on their arcuate flow path through the duct (20) in the remaining flue gas to a solids collection means (40) opening to the solids outlet (26) of the arcuate duct (20).

Abstract: A joint between a pair of coaxial tubes (14, 20) which extend into a pressure vessel (12) from a surface (16) is sealed using a sleeve-like housing (30) which surrounds the joint to be sealed. An upper fluid-tight seal (46) is formed between the longer of the tubes (20) and the housing (30). A lower fluid-tight seal (36) is formed between the housing (30) and the surface (16). An intermediate seal (40) is also formed between the housing (30) and the shorter tube (14). The upper and lower seals (46, 36) are independently preloaded through the use of spring washers (52, 58). Primary loading of the lower seal (36) to the surface (16) is caused by fluid pressure in the vessel (12) which acts on the housing (30).

Abstract: A probe (8) for inspecting the walls of a tubular conduit (40, 42) or the like is provided with a pair of movable arms (20a, 20b) urged outward from a central rod (4) into contact with the tube interior. Eddy current coils (16, 18) carried in the tube engaging ends (32a, 32b) of the arms (20a, 20b) are maintained in a constant, spaced apart relationship with the tube wall interior for increasing inspection accuracy and sensitivity. The movable arms (20a, 20b) can accommodate varying internal tube diameters, expanding and contracting relative to the central rod (4). A sloping nose (2) and tapered arm portions (32a, 32b) assist the probe in traversing the conduit interior.

Abstract: A system (10) for determining the thickness of a magnetic flux conductive clad material over a magnetic flux conductive base material of different permeability applies an alternating voltage (96) to the primary winding (52) of an incomplete core-type transformer (54). The secondary winding (40) voltage to primary winding (52) voltage ratio is determined with the material being clad-thickness measured (56) completing the incomplete core (54). The voltage ratio is a nondestructive measurement of the thickness (64) of the clad material. The preferred embodiment applies a constant voltage alternating voltage power source (18) to the primary winding (52). This obviates the need to determine the ratio of voltages. The secondary winding (40) voltage is a direct nondestructive measurement of the thickness (64) of the clad material. By reference to a particular clad material-base material chart, the clad thickness is read from the scale adjacent the intersection of the voltage induced in secondary winding (40) and the curve (78, 80, 82, 84, 86, 88, 90, 92, 94) representing the composition of the clad material.
