Abstract: A push chain is used to drive a piston into a canister of extrudable material. The push chain is stored in an elongated chain magazine, withdrawn from the magazine and into the canister by actuation of a trigger connected to a sprocket for the chain. The push chain obviates the need for an elongated piston rod used in conventional extrudable material dispensers.

Abstract: A piston and piston rod for a rodless dispenser for extrudable material are configured such that compressive force exerted on the piston from a push chain causes a reactive torque to be created that locks the links of the chain together. The push rod is located away from the piston's geometric center.

Abstract: A push chain is used to drive a piston into a canister of extrudable material. The push chain is stored in an elongated chain magazine, withdrawn from the magazine and into the canister by actuation of a trigger connected to a sprocket for the chain. The push chain exerts a compressive force on a piston rod connected to a piston at a point offset from the center line of the piston, causing the piston to rotate to lock the push chain. The amount of material remaining in a tube of extrudable material is enunciated by way of a contents indicator driven by the push chain.

Abstract: A food product steamer includes rotatable platforms that can be covered and uncovered by one or more rotatable, concave hoods. In a first position for the platform(s), the platform(s) supports a food product over a steam-emitting opening above a steam generator. In a first position for the hood, the hood covers the food product such that steam from the steam generator is trapped within the hood to steam the food product. In a second, open position, the hood is rotated where it can receive the food product when the food product slides or falls off the platform as the platform is rotated from its first position to a second, elevated position. At least one embodiment enables food products to be removed from either side of the steam generating base by using a double-acting hinge.

Abstract: One or more piezoelectric devices cool or heat a thermally-conductive basin. The basin is sized, shaped and arranged to receive two or more food serving trays. In a preferred embodiment, the food serving trays are sized, shaped and arranged to provide an air gap between the tray and the thermally-conductive basin so that the tray is cooled by convection and radiation but not conduction.

Abstract: A method of toasting a food product like an English muffin irradiates the food product with infrared (IR) energy from an infrared energy source while simultaneously directing an unheated air stream toward the food product.

Abstract: A temperature controlled food storage unit is provided with a Peltier device (18) to effectuate the temperature of food place in a thermally conductive container or basin (24). Air from a fan (52) is passed through an air duct (50) and over a heat sink (22), which is thermally coupled to one side of the Peltier device (18). A hand-operated damper (54, 64) is used to control the air flow through the air duct (50) and over the heat sink (22) thereby controlling heat exchange between the Peltier device (18) and ambient air.

Abstract: Passive temperature control is provided to vessels too tall to be stored in a shallow, temperature-controlled tray or basin by a vertically oriented thermally-conductive tube. In one embodiment, an insulative collar covers the tray and insulates portions of the tube that extend above the top of the tray. Optional heat sinking fins and air convection holes increase heat transfer between the tube and the tray.

Abstract: A food heating device usable as a toaster, fryer or warmer uses a metal plate having separately heated regions separated by a thermal break. The separately heated regions use separately energized and controlled heating elements embedded to the material from which the metal plate is made. One region can be kept hot while the other region is shut off or kept at a lower temperature until demand requires both sides to be heated. Separating the regions by a thermal break reduces heat transfer from the hot side to the cool side.

Abstract: A spatula (200, 700, 900) has a platform (201, 701, 901) having an opening bounded by a food support (205, 217, 221, 223). At least a part of the food support (205, 217, 221, 223) supports a food product, such as a bread product, for steaming or toasting. An optional guide (209, 609, 909) is disposed on one side of the platform (201, 701, 901). The guide (209, 609, 909) is configured to align the food product with a package (501) arranged and sized to contain at least the food product. The platform (201, 701, 901) optionally has one or more segments (703, 705) that rotate away from the platform (201, 701, 901).

Abstract: A steamer for sandwich buns, bagels, croissants, cakes, vegetables, pastas, and other foods delivers fixed amounts of water onto a hot, dry platen through a vertically-oriented water conduit which is also thermally insulated from the hot platen and made from thermally insulating materials. The vertically-oriented water conduit retains water after a water supply is shut off at the beginning or end of a steam generating cycle. Orienting the conduit vertically reduces the surface area of liquid water exposed to air. Insulating the water conduit from the hot platen reduces the rate at which water standing in the conduit evaporates. Tubes used in the water conduit are insulating and easily removed from the water conduit assembly and flexible. Minerals that precipitate out of solution and become deposited onto the flexible tube are easily removed by flexing the flexible tube.
