摘要:
A push chain (24) is used to drive a piston (26) into a canister (21) of extrudable material (23). The push chain is stored in an elongated chain magazine (32), withdrawn from the magazine and into the canister by actuation of a trigger (16) connected to a sprocket (22) for the chain. The push chain obviates the need for an elongated piston rod used in conventional extrudable material dispensers.

A motion transmitting drive chain (50) is prevented from buckling by applying a relatively small compressive bias force to one side of the pins (56) around which the chain links (52) rotate. The bias force is applied on the locking projection (58) side of the pins axes of rotation such that the links are urged to rotate in the direction required to lock them against each other.
摘要:
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.
摘要:
A method of surface toasting a bread-type food product, comprising the steps of: providing a toasting apparatus having a fixed heated platen (40) and a movable platen (44); depositing a product between the platens while in spaced condition; moving the movable platen (44) toward the fixed platen (40) to bias the product against the fixed platen and surface toast the product; backing the movable paten (44) away from the fixed platen (40) an amount sufficient for the product to expand but not completely release the product from the fixed platen; and moving the movable platen (44) completely away from the fixed paten (40) to completely release the product from the fixed platen.

A pass thru food warming apparatus is shown with a housing defining open rear and front ends between which food products can be passed. A generally horizontal grate extends between the open rear and front ends of the housing and on which the food products can be supported. A heating platform is mounted beneath the grate for warming the food products supported by the grate. The heating platform includes a generally horizontal top plate, a radiant heater and sensor assembly immediately beneath the top plate for heating the top plate, and a generally horizontal bottom plate spaced beneath the heating device to define a cooling chamber therebetween. The heater and sensor assembly includes a substrate having a select size and shape defining a plurality of heated zone areas. An elongate foil heater conductor is secured to the substrate in each zone area. The heater conductor extends about the substrate in a first select pattern to generate heat proximate thereto. An elongate foil sensor conductor is secured to the substrate in each zone area. The sensor conductor extends about the substrate proximate the heater conductor in a second select pattern, generally similar to the first select pattern, so that the sensor conductor senses temperature of the entire zone area.

A pass thru food warming apparatus is disclosed with a housing defining open rear and front ends between which food products can be passed. A generally horizontal grate extends between the open rear and front ends of the housing and on which the food products can be supported. A heating platform is mounted beneath the grate for warming the food products supported by the grate. The heating platform includes a generally horizontal top plate, a radiant heating device immediately beneath the top plate for heating the top plate, and a generally horizontal bottom plate spaced beneath the heating device to define an insulating chamber therebetween. A generally hollow insulating chamber also is provided along either one or both of the front and rear edges of the heating platform.

A push chain (24) is used to drive a piston (26) into a canister (21) of extrudable material. The push chain is stored in an elongated chain magazine (32), withdrawn from the magazine and into the canister by actuation of a trigger (16) connected to a sprocket (22) 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 content indicator driven by the push chain.
