  • Patent number: RE33176
    Abstract: A method for determining the density of coal or other bulk material in a stockpile includes boring a calibration hole into the pile and collecting at least a portion of the cuttings thus obtained into a container. A series of readings are taken within the container with a nuclear depth-density gauge, and the weight of the cuttings and container volume is measured. The measured weight and volume are compared with the gauge readings to calibrate the gauge. A test hole is then bored substantially to the bottom of the stockpile, and a section of steel casing is inserted and partially pressed into the hole. A second section of casing is attached to the first and similarly pressed into the hole. In this manner, casing is extended the full depth of the hole. Readings are then taken at various depths therein with the nuclear gauge. From the data thus obtained, average density throughout the pile is determined.

  • Patent number: 4905320
    Abstract: A protective body support for use to protect a wearer's knee, or other such body part, re-directs and dissipates the forces associated with an impact delivered to the body support in such a manner as to prevent the application of a force to the body that is sufficient to harm that body. The body support includes plurality of triangular compartments that are attached at the apex of the triangles to an adjacent element of the support. Energy-absorbing beads are contained in the compartments, and the triangular shapes are oriented so that forces applied to the support are re-directed against the apexes so as to apply shear forces thereto. The apexes are attached so that at a predetermined level of impact force applied to the support, the resultant component applied against the apexes will rupture at least one of the apex connections thereby allowing the beads to spill out of the support compartment located adjacent to the ruptured apex.

  • Patent number: 4905322
    Abstract: An energy-absorbing sound-attenuating earcup comprises a rigid shell of an ABS terpolymer that is about 0.090 inch thick so as to crush upon impact at an applied force less than that required to crush the skull of the wearer. The shell has an inner coating of a sound-deadening rubber material to compensate for the reduced sound-attenuating capability of the thinner-than-normal shell. Spaced flanges defining a peripheral channel for receiving a cord of a helmet suspension are formed as staggered series of tabs rather than as circumferentially continuous members to facilitate crushing of the shell upon impact. Resilient earseals disposed between the shells and the wearer's ears comprise first thicknesses of standard polyurethane foam and second thicknesses of slow-recovery polyurethane foam to provide additional impact absorption while permitting the earseals to conform to the wearer's head in cold weather when the helmet is first put on.

  • Patent number: 4905328
    Abstract: A sofa-bed assembly comprising a rear vertical section, a lower horizontal section, a front vertical section, and an upper horizontal section pivoted to one another in succession for folding movement between a collapsed sofa condition and an extended bed contidion. A mattress folded within the assembly presses upwardly against the upper horizontal section, and a locking linkage arrangement resists the tendency of the folded mattress to swing the upper horizontal section upwardly out of a horizontal plane when the assembly is in its collapsed condition. Release of the locking linkage involves initially compressing the mattress further, thereby increasing the force required to open the bed. Additional links respond to unfolding of the rear leg, which supports the unfolded lower horizontal section for relieving some of the pressure of the mattress on the upper horizontal section, thereby reducing the force required to open the locking linkage to permit unfolding of the upper horizontal section.

  • Patent number: 4905347
    Abstract: A removable torque rod assembly for a self-closing door which may be easily installed on a door and an anchoring device mounted to an underlying door frame. The torque rod assembly may be used for either a left- or right-handed door. The assembly uses a torque rod located inside a metal sleeve having the sleeve crimped or attached to or otherwise made integral with the rod at its top end so that the rod and sleeve act together at the top end. The lower end of the torque rod passes through a bushing attached to the sleeve and through a bushing cap surrounding the bushing. A resilient O-ring fits into an annular groove in the bushing. The torque rod assembly is installed on the door by forcing the O-ring past an aperture in the door so that the O-ring holds the assembly on the door and a head of the bushing mates with the aperture in the door. The lower end of the torque rod assembly is then mounted in an anchoring device which keeps the lower end of the rod from rotating.

  • Patent number: 4905351
    Abstract: An airline cleaner has a cylindrical cage coaxial and the same diameter as a pipe connected to either end of the cage. Helical vanes around the circumference of the cage cause the air and seed cotton moving through the pipe in the cage to move in a helical motion as they move through the cage. The helical motion will wipe the seed cotton against the cage, and trash will fall through spaces in the cage, thus being removed from the seed cotton. A housing surrounds the cage.
