  • Patent number: 7397041
    Abstract: Apparatus for sanitizing objects by use of ultraviolet light includes an enclosed container defining a first object entry opening and a second object exit opening. A first inclined slide is mounted within the container and is positioned adjacent to the first entry opening, and a second inclined slide is mounted within the container beneath the first slide and positioned adjacent to the second exit opening. The slides are positioned at angles with respect to horizontal such that the pull of gravity on the objects moving down each of the slides is greater than restraining electrostatic or frictional forces on the objects. A baffle is mounted within the container and is positioned with respect to the slides for redirecting objects from the first slide onto the second slide, and ultraviolet light sources are mounted in the container and positioned above the slides for irradiating the objects as they move down the slides.

  • Patent number: 6581998
    Abstract: An improved carrier apparatus for use by fire fighters to carry fire hose and to serve as a personnel carrier includes an elongate bottom, a first end wall connected to the bottom and first and second opposed and spaced apart side walls connected to the bottom and to the first end wall. A second fire hose retaining end wall is movably connected to the first side wall for removable connection to the second end wall. A gap is formed between a lower edge of the second end wall and the elongate bottom when the second end wall is removably fastened to the second side wall to permit water and debris to pass out through the gap while preventing the fire hose from falling out of the carrier prematurely.

  • Patent number: 6547231
    Abstract: A newspaper inserting machine for inserting supplements or inserts into signatures or newspaper jackets improves upon conventional inserting machines by modifying the conventional inserting machines existing belt gripping mechanisms for gripping the inserts and for propelling the inserts into the newspaper jackets as the jackets are moved by a conveyor past insert-containing containers. The existing belt gripping mechanisms are modified to be adjustably positionable to accommodate inserts of different thicknesses and are also modified to be adjustably positionable in directions parallel with the conveyor to accommodate inserts of different sizes while reducing the machine set-up time required by operators for different sizes of inserts. The adjustability of the belt gripping mechanisms also increase the capacity of conventional machines for the number of different inserts which can be placed into the newspaper jackets along a conveyor of predetermined length.

  • Patent number: 6516727
    Abstract: A high capacity, multiple-stage railway car switching yard connects together two or more subyards. Each subyard has a fully open arrival/departure end and may have a continuously descending gradient throughout the entire length of its classification tracks. The subyards are positioned opposite one another, so classification tracks of one subyard can serve as receiving tracks for another subyard. Escape tracks are interconnected between the two subyards to provide a higher capacity and more efficiency and flexibility than a single yard by itself.

  • Patent number: 6418854
    Abstract: A new method of sorting railroad cars in yards is presented, whereby outbound trains are built in proper standing order for departure directly on classification tracks, using a continuously sustainable multi-stage sorting process. During this process, cars are easily separated based on priority or according to their delivery time commitments, so connections of cars needing to go on a specific train can be protected. During second stage sorting operations, railcars may be inspected or repaired while they await outbound connections on classification tracks, effectively utilizing otherwise idle time and resulting in considerable savings in time required for railcars to pass through the yard. The need for a separate departure yard, along with the bottleneck “flat” switching operation at the departure end of the classification yard, is also eliminated.
