Abstract: A prefabricated chimney assembly of the dual-wall type, adapted to be coupled to the flue outlet of a fireplace, is disclosed. The chimney assembly includes an inner conduit extending the length of the chimney assembly to form the flue through which combustion gases flow upwardly, and an outer conduit mounted in spaced relationship to the inner conduit so as to define an annular passage for conducting only outside air downwardly therethrough.
Abstract: This efficient checking account record keeping and check disposal system, including a method of producing the negotiable instruments for the system, provides checks and check stubs on which information pertinent to the functioning of a checking account may be stored conveniently and efficiently. The invention also is directed to a method of printing the checks and stubs in which the "safety paper" background design may be selectively printed and in which information spaces on the back of said stubs may be printed along with the printing of the background design in one operation.
Abstract: A seal assembly arranged and constructed for an operable or portable wall panel to provide top, bottom or side seals therefor is disclosed. A channel shaped member is mounted in the panel in fixed position, with the open end of the channel extending outwardly to an edge thereof. A seal actuator means is operatively coupled to a spring loaded, shiftable seal assembly which is mounted in the channel and is held in a latched, retracted position. The spring-loaded seal assembly is shifted inwardly of the channel to release a latch means so that the springs are released to permit the seal assembly to shift outwardly of the channel to its extended, self-leveling sealed position.
