The present invention is directed to a ball including an outer shell formed from a first thermoplastic material and having an inner surface defining a cavity, outer details formed from a second thermoplastic material and disposed on at least a portion of the outer surface of the outer shell, and a core formed from a foamable polymeric material and disposed within the cavity of the outer shell. The ball may be produced by forming a pair of half shells having inner surfaces defining corresponding portions of the cavity of the outer shell, forming the outer details on the outer surface of at least one of the half shells, and foaming a polymeric material to form the core.

In a method and apparatus for identifying and distinguishing fungal species, a hyperspectral imaging scanner is used to acquire hyperspectral image data for radiation obtained from a sample area in which at least one unknown fungal species is present. A computer compares the acquired hyperspectral image data with spectral signature data stored in a digital library, which includes spectral signature data for each one of a group of known fungal species, and identifies the fungal species, based on the result of such comparison. The spectral signature data stored in the digital library take into account, for each fungal species, spectral variations that can occur due to at least one of environmental and temporal influences. The computer comparison includes a pixel-by-pixel analysis of the degree of difference between acquired hyperspectral image data and the spectral signature data, so that a spatial distribution of identified fungal species can be determined for a sample area.

Improved features for a filter system for a deep fat fryer are described. The fryer includes a movable filter pan disposed below the cooking tank which is fed by gravity when the tank is drained through a downspout. The downspout is curved and rotatable from a down position when it is in use/storage to an up position when it is not in use and a stabilizing clip is mounted on the downspout to secure a separate polishing tube when it is in the down or horizontal position to allow one handle to lift two pipes at the same time for removal of the filter pan. An inline removable filter is provided in the oil return line, and the return line is slidably supported on the side of the filter pan so that it can rise and fall with the debris in the filter pan.

A metering apparatus 10 for continuously supplying a specified amount of fluid material F to a desired surface. The apparatus 10 includes a reservoir 14 for maintaining a supply of fluid material, a housing 16 having a central bore 22 therethrough, a receiving opening 24 for receiving fluid material from the reservoir 14 to central bore 22, and an exit opening 26 through which fluid material exits the housing 16. A rotatable screw member 28 is provided engaged through the housing 16 within said central bore 22, and a driver 37 engaged with the screw member for rotating the screw member within the bore at between approximately 1 rpm to 2,700 rpm, and preferably approximately 1,750 rpm, in order to continuously supply fluid to the exit opening 26. At this operating level, fluid material is provided from the exit opening 26 at a flow rate of between approximately 1 to 23 grams/min, and in a thickness of approximately 0.001 to 8 mils. The reservoir 14 includes a tank 50 for the fluid material, and a motor 68 for agitating the fluid during operation of the apparatus 10. The housing 16 is secured adjacent the tank 50 to provide the fluid material from the tank to the receiving opening 24.

A rotatable electrical connector or swivel is used in a substantially vertical subterranean portion of a drill string within a drill pipe. The swivel has an enclosed oil filled chamber having a first shaft concentrically mounted therein. The first shaft protrudes from the chamber and is electrically connected to one end of a wireline which is used for electrical connection between the surface and instruments located downhole. Within the interior of the oil filled chamber the first shaft is attached to a first member disposed within the complementary surface of a second member concentrically aligned with the first member. The second member includes a second shaft which protrudes from the oil filled chamber and is connected to the other end of the wireline. One of the two shafts is rotatably mounted in bearing within the chamber so that the complementary surfaces of the first and second members are in the relationship of a rotor and stator. Continuous, electrical contact between the rotor and stator surfaces are assured by placement of a plurality of berrylium copper wire spring wipers between the rotors and stators. The enclosure of the oil filled chamber, includes an elastic member which permits equalization of the internal oil pressure within the chamber with the external hydrostatic pressure of the drilling fluid or other fluid present in the drill pipe.

A windrow-type paving machine movable along a windrow of paving material includes a loading conveyor operable to transfer the upper portion of the paving material within the windrow into a hopper. The remainder of the paving material remains on the roadway and passes through a tunnel formed in the paving machine to a lateral auger and screed which cooperate to spread and level the paving material. The machine provides a hopper which receives the upper portion of the paving material for subsequent delivery by a conveyor to the lateral auger and screed when insufficient paving material passes through the tunnel to produce the required paving. Agitator means are provided in the tunnel to break up lumps of paving material and the like before they reach the auger.
