Abstract: Escutcheons for a temperature-controlled food holding cabinet are removable and field replaceable by the use of interlocking keys and keyholes that hold the escutcheon in place and align the escutcheon to electrical connectors. The escutcheons are provided with illuminated user interfaces. A key formed on either the escutcheon or chassis of the cabinet, engages a corresponding keyhole formed on either the cabinet chassis or the escutcheon.

Abstract: An improved coupler body having an area of increased material in the upper lock chamber.

Abstract: A finger core for forming the front part of a knuckle for a railcar, said finger core comprising a single opening to form a single rib at the horizontal center line of the resulting knuckle.

Abstract: A railroad coupler knuckle includes a single, solid rib at a horizontal centerline of the knuckle that passes through a pivot pin hub thereof. The single, solid rib extends generally from a flag hole of a finger cavity of the knuckle to an opposite side of the knuckle from the flag hole. In another aspect, a railcar coupler knuckle includes a tail section, a hub section, and a nose section. The tail, hub, and nose sections define internal cavities including (i) a combined void that defines a pivot pin hub cavity and a kidney cavity and (ii) an isolated finger cavity. The combined void is formed using a first internal core during manufacturing of the coupler knuckle. The isolated finger cavity is formed using a second internal core during manufacturing of the coupler knuckle, such that molten alloy substantially separates the combined void and the isolated finger cavity.

Abstract: A coupler body for a railcar coupler, said coupler body comprising at least one central datum feature that does not wear during coupler use.

Abstract: An improved lock for a railroad coupler, said improvement comprising a chamfer on a knuckle shelf seat.

Abstract: A method for manufacturing a railcar coupler knuckle includes providing cope and drag mold portions having internal walls defining at least in part perimeter boundaries of a knuckle mold cavity; positioning a first internal core within either the cope mold or the drag mold portions, the first internal core configured to define a kidney cavity and a pivot pin hub as a single void within the knuckle; positioning a second internal core within either the cope mold portion and the drag mold portion, the second internal core configured to define a finger cavity; closing the cope and drag mold portions with the two internal cores therebetween; and at least partially filling the mold cavity with a molten alloy, the molten alloy solidifying after filling to form the knuckle, wherein the first internal core defines the kidney cavity and the pivot pin hub of the coupler knuckle, and wherein the second internal core defines the finger cavity of the knuckle.

Abstract: A volumetric displacement dispenser and method of using the dispenser is disclosed for dispensing liquid contents from an interior of a bottle with a bottle neck while preventing air from filling a void created within the interior of the bottle caused by the liquid contents being poured out of the bottle by gravity. The dispenser includes a stopper having first and second boreholes extending there through, the stopper being adapted to form an air-tight seal when it is seated into the bottle neck. An air pressure tube routed through the first of the boreholes has a first end open to atmospheric air and a second end open to the interior of the bottle. An expandable volumetric displacement balloon is attached to the second end of the air pressure tube and a one-way liquid valve is disposed in the outlet of the liquid flow channel in the stopper.
