Notice of Acceptance of Complete Specifications.

Patent Office,
Wellington, 30th October, 1901.

COMPLETE specifications relating to the under-mentioned applications for Letters Patent have been accepted, and are open to public inspection at this office. Any person may, at any time within two months from the date of this Gazette, give me notice in writing of opposition to the grant of any such patent. Such notice must set forth the particular grounds of objection, and be in duplicate. A fee of 10s. is payable thereon.

No. 13093.—26th October, 1900.—ALLAN CAMPBELL, of 1434, West Monroe Street, Chicago, Illinois, United States of America, Manufacturer. Improvements in refrigerating-apparatus.

Claims.—(1.) The combination in a condenser coil with a continuous water-pipe coil, of straight sections of gas-pipe surrounding the straight sections of said water-pipe between the return bends thereof; the top section of said gas-pipe having an intake between its ends, and the bottom section thereof having an outlet between its ends; and said sections of gas-pipe communicating at its ends with a companion section on one side and at a suitable point between its ends communicating with the companion section on the other side of it. (2.) The combination in a condenser coil with a continuous water-pipe coil, of a gas-pipe surrounding the straight portions thereof that has its gas-intake located between the ends of the top section thereof, and its outlet between the ends of the lower section thereof, and each section of which is connected at its ends and at a suitable point between its ends, so that the gas is divided into two oppositely moving currents that travel back and forth to said outlet in that end portion of the condenser into which it originally passed. (3.) The combination in a condenser coil for refrigerating-machines with a continuous water-pipe coil A, of sections of gas-pipe B, two of which surround the greater portion of each straight part of coil A, T-couplings C connecting each two aligning sections of gas-pipe, and connected with the corresponding coupling of the next adjacent parallel aligning sections of gas-pipe on one side, and T-couplings E on the outer ends of said sections of gas-pipe connected with the corresponding coupling E on the ends of the next adjacent parallel aligning section of pipe B on the other side of it, as and for the purpose set forth. (4.) The combination in a condenser coil of a refrigerating-machine with a continuous water-pipe coil A, of sections of gas-pipe B, two of which surround the greater portion of each straight part of coil A, T-couplings C, which have inwardly projecting spacing-lugs for centring said water-pipe and connecting with the corresponding coupling D of the next adjacent parallel aligning sections of pipe B on one side, and T-couplings E secured to the outer ends of said sections of gas-pipe, which, connected with the corresponding coupling E on the end of the next adjacent parallel aligning section of pipe B on the other side as and for the purpose set forth. (5.) In a refrigerating-apparatus, a continuous coil of pipe through which a liquid is forced, of a series of corresponding sections of pipe of larger diameter enclosing the straight stretches of said continuous coil, and coupling-devices connecting the ends of the same to their fellows, so as to make a conduit for a gaseous product moving in the opposite direction to the liquid in said inner pipe, as and for the purpose set forth.
