Abstract

164,294. Nitro-Fixation Syndicate, Ltd., and Jenkins, H. C. Dec. 6, 1919. Plate apparatus.-The media between which heat is to pass flow in opposite directions in passages constructed from flat strips 2 with end fillets 3 wound spirally. On reaching the outer convolution, the end of each strip is bent back for half a turn and secured to the point 4 at which the other was bent. In the example shown, one medium enters at an annulus 7 and escapes at 6, the other entering at 5 and passing through the central tube 1. A pressure-resisting surround 10 may be provided. Specifications 9815/94, 24404/01, and 159,965 are referred to.
