Abstract: A device (10) for use in monitoring or measuring properties of a moving bed (11) of particulate material includes a sled (12) that rides or floats on the top surface (15) of the moving bed (11). A mounting structure (14) holds the sled (12) stationary with respect to the linear movement of the particulate bed (11), but permits movement of the sled (12) in a direction perpendicular to the movement of the bed (11), such as up and down when the bed (11) is moving horizontally. The sled (12) can carry on board sensors (76) to monitor the particulate material properties. Other sensors (72, 54) can be located remote from the sled (12) such as a sensor (54) to indicate displacement of the sled (12) in a direction perpendicular to the direction of travel of the moving bed (11). In one embodiment, the device includes a flume-like collector that directs particulate material through a sampling cell comprised of parallel side walls (47, 48) with the sensor sled (12) located between the sidewalls.

Abstract: This invention is a method for forming a chemical conversion coating on ferrous metal substrates, the chemical solutions used in the coating and the articles coated thereby. By modifying and combining the features of two existing, but heretofore unrelated, coating technologies, a hybrid conversion coating is formed. Specifically, a molecular iron/oxygen-enriched intermediate coating, such as a dicarboxylate or phosphate, is applied to a ferrous substrate by a first oxidation. The intermediate coating pre-conditions the substrate to form a surface rich in molecular iron and oxygen in a form easily accessible for further reaction. This oxidation procedure is followed by a coloring procedure using a heated (about 120-220° F.) oxidizing solution containing alkali metal hydroxide, alkali metal nitrate, alkali metal nitrite or mixtures thereof, which reacts with the iron and oxygen enriched intermediate coating to form magnetite (Fe3O4).

Abstract: A wedge-soled bowling shoe has selectable percentages of regions of different coefficients of friction of traction characteristics and different coefficients of friction of slide characteristics on a shoe sole surface. The shoe gives the bowler precise control over relative amounts of slide and/or traction action of each shoe. The bowler can readily change the relative amounts of slide and/or traction action of each shoe by changing a replaceable sole member of the desired percentages of regions of high or low traction and high or low slide to accommodate differing conditions and differing styles of bowling. Using one of a plurality of pairs of replaceable sole members, a first member of each pair is constructed of two materials, each of a different coefficient of friction to provide slide characteristics and a second member of each pair is constructed of two materials, each of a different coefficient of friction to provide traction characteristics.

Abstract: A rotational molded boat or equivalent floatable marine structure has parallel hull walls interconnected by rows of spaced apart, molded V-shaped connectors. The connectors are formed in the rotational molding process. One of the mold sections has a mold surface for forming one of the hull walls, said surface having one or more rows of V-shaped indentations projecting toward an opposite mold surface. The V-shaped indentations have apexes that are spaced apart from the opposite mold surface by a distance that, during the molding process, will fill with molten material to form a molded connection between the finished hull walls. In another embodiment, a lattice structure is assembled to the mold and molded in between side wall components of the hull.

Abstract: A tapered part measuring apparatus and method measures male and female tapered or conical parts. The apparatus and method use non-contact linear measurement technology for accurate and repeatable measurements, particularly of tapered parts with large deviations from their desired measurements. The tapered part suspends in non-contact position to the non-contact linear measurement probe on a true vertical axis to accurately assume the same position on replicate measurements.

Abstract: A hot air slurry dryer having a cylindrical housing with a central shaft rotatably mounted in the housing. Material to be dried moves from an upstream end of the housing to an outlet at a downstream end. A hot air inlet is connected to the upstream end of the housing preferably at an upstream end wall. A material inlet is open to the side wall of the housing downstream of the hot air inlet. The shaft carries structure for breaking up the moist material introduced into the housing and mixing it with the hot air. In a preferred embodiment a drum is carried by the shaft at the inlet end of the cylindrical housing. The drum carries a plurality of agitator blades that pass close by the interior surface of the side wall of the housing.

Abstract: A cutting board combination for use with a double basin sink having a sink divider separating the two basins. The cutting board combination includes a first cutting board that has a flat upper cutting surface and a pair of spaced apart legs fixed to the bottom surface. The legs are spaced apart to straddle the sink divider with the cutting board base supported on it with lateral edges overlapping the sink basins on either side. The cutting board combination includes a second cutting board that can be connected at an inner lateral edge to a lateral edge of the first cutting board. The second cutting board is connected to the first in such a fashion that the work surfaces of the two are coplanar. The inner lateral edge of the second cutting board is supported by the first cutting board. The second cutting board has a length sufficient so that it spans the sink basin with the outer lateral edge supported on the sink rim.

Abstract: Devices for injection of medicines into a human body are designed for one-time use during inpatient or outpatient treatment. The reuse of an injection device having a bellows 3 as an injection container is prevented by providing a locking attachment which prevents backward motion of a bottom 4 of the bellows 3 and which is mounted on elements of the device brought together during the injection (the bottom 4 of the bellows 3 and the housing/needle holder 1). A locking attachment is made in a form of a pair of interacting elastically deformable hooks 6 with a beveled catch and a female part in the form of a hole 7 with a ledge 8. At the instant the injection is completed, the sharpened end 10 of the needle 2 punctures a partition 9 in the bottom 4 of the bellows 3, further preventing reuse.

Abstract: A bowling shoe with a replaceable tip comprises a shoe upper, a shoe sole mounted to the shoe upper, and a plurality of replaceable shoe tips. The shoe sole has a selectable traction area from a toe end and across the width of the shoe sole. Each tip has a margin substantially equal to a margin of the traction area. Each tip covers and conforms to part of the adjacent shoe upper. The surface of each tip has a different coefficient of friction. A selected tip secures to the traction area and part of the adjacent shoe upper. The tips are interchangeable, to provide traction according to support surface conditions and an individual wearer's preference.

Abstract: An extrusion calibrator, to calibrate the exterior profile of a thermoplastic extruded product exiting from an extrusion die, has a modular calibrating cassette of calibrating plates in a surrounding shell. One calibrating cassette is readily interchangeable within the shell for another calibrating cassette of a different extruded product cross-sectional profile. The cassette plates have planar surfaces, free of fluid-conducting pathways, which greatly reduces the time, cost and skill required to establish vacuum and coolant conducting routes through the extrusion calibrator. Fluid conducting routes to conduct vacuum and coolant through the calibrator are established by vacuum and coolant conducting manifolds and channels in the shell interior and by interplate spacings mating with these channels.

The dental pieces have interlock means that hold them together with the jaws in a position of correction. Occlusal surfaces can be provided to permit chewing of food while the appliance is worn.

Abstract: A cubic magnetic core storage memory system which results in increased packing density of the core elements and more economical construction. Memory cores are bonded flat to carrier planes. The carrier planes are then stacked, forming a three dimensional array which is wired with X, Y and sense/inhibit lines. A parallel group (word) of binary digits is geometrically defined by a vertical line drawn through memory cores on the common intersection between an X and a Y coordinate wire on the successive carrier planes of the three dimensional array.
