摘要： An entrance doorway for electrostatic precipitators, bag houses, scrubbers, ductwork and breeching includes an interior metal plate door hinged to a frame plate of similar thickness whereby the interior door and frame plate will follow any warpage of the casing wall as they are subjected to the same temperatures as the casing wall. A hollow core high temperature acid-resistant resilient gasket is employed between the interior door and its frame plate. A pressure screw acting on the center of the interior door flexes it toward the interior of the casing and renders the interior door concave to form a tight seal with the gasket. An interior door retractor is provided to pull the interior door and its gasket away from the frame plate when the pressure screw is relieving pressure on the interior door, thereby preventing damage to the door gasket. An adjustable length telescoping sleeve fixed to the interior door frame plate extends away from the interior door and supports a lightweight thermally insulated exterior door panel which is removably secured by corrosion-resistant latches. The door system eliminates air infiltration and corrosion.

摘要： A door system for a boiler penthouse or other high temperature industrial environment is disclosed. A sufficiently large entranceway for both workmen and large equipment is provided by the door system. The access door has the capability for quick gas-tight sealing during closing. A hinged metal door plate has arcuate welding beads applied to its internal surface near its corners to produce permanent inward cupping of the door plate adjacent to its corners. Devices apply pressure to the exterior surface of the door plate during the closing thereof to flatten the inwardly cupped corners and effect gas-tight sealing of the interior surface of the door plate near its margin with an opposing high temperature resistant gasket carried by the front face of a refractory insulated door frame. A layer of thermal insulating material in a protective jacket is secured to the interior surface of the door plate.

摘要： A litter screening and separating apparatus including a storage compartment arranged for towed movement, a loader structure affixed at one end of the storage compartment for picking up encrusted litter material from floors of chicken houses, a conveyor including a pair of chains for moving the encrusted litter from the loading structure to the storage compartment, a baffle plate adjacent and beneath the conveyor chain for preventing contamination of the conveyor chain from the material stored in the storage compartment, a plurality of loading panels arranged between the pair of chains and being replaceably affixed thereto, and vibrator rollers adjacent the pair of chains for engagement with projections on spaced links of each chain for vibrating the loading panels. The loading panels may be of solid panel construction or of expanded metal, depending upon the type of litter being picked up and the method of use of the apparatus.
