Straight tubes between headers; loop tubes; tube - supports; expansion and contraction of tubes, providing for; gills for tubes.-One heat exchanging fl u i d passes around, and the other through. a plurality of elements each comprising a number of tubes 2 interconnected at one end as by a header 4 and fixed at the other in the tube plate 3 of a divided header and parallel gill-plates associated with all the tubes of each element. The main header is divided by plates 5 so that the fluid passes through the elements of groups of rows in parallel. The plates 5 may be constituted by a single zig-zag partition. The tubes in each element may be unequally disposed with relation to the dividing plate 5, so that, for example, fluid passes outward through more tubes than are passed in returning to the main header. The headers 4 are supported by means of a prong 6 sliding in a hole in strips 7, each of which may support more than one row of headers. Intermediate tube supports are formed by suitably shaped blocks 14, 15 clamped over the tubes, shown as two in each element, and adapted to rest on one another and upon a notched bar 16 around the casing 1. Specification 217,564 is referred to.

Filed: 1927-02-02
Abstract: 265,587. Billand, C. Feb. 2, 1926, [Convention date]. Centrifugal machines; casting-apparatus.-Pipes are cast in centrifugal moulds arranged vertically. The mould a, Fig. 1, is rotated by a belt and pulley 33 and the material is applied progressively by a pipe c commencing at the top or the bottom. Either the mould or the pipe c or both may be moved axially and, if desired, the pipe c may also be rotated in the opposite direction. The end of the pipe c is provided with one or more nozzles e, curved in the direction of rotation of the mould. The mould may be shaped and provided with a core u, Fig. 7, at one or both ends to produce a socket and an overflow chamber r may be provided at the end where the casting is completed. A jacket 41, filled with cooling medium, may also be fitted. The level of the material in the funnel y is kept constant by tipping the ladle w until the nozzles e<2> approach the end of their travel, this point being preferably indicated by an electric device. The ladle, funnel, and pipe b are preferably carried by a vertically movable car 54. A plurality of moulds may be mounted on an intermittently rotated table 57, Fig. 17<a>, by which they are brought singly or in groups into casting position. While the moulds 1 to 4 are being filled by one or more ladles w, the pipes previously cast are being extracted from moulds 9 to 12. The cores v may be inserted by mechanical means u, Fig 17. The moulds may be rotated by one or more electric motors t carried by the table or by a fixed motor brought into driving engagement with each mould in'turn. The Specification as open to inspection under Sect. 91 (3) (a) also states that the material cast may be non-metallic e.g. hydraulic cement and comprises modifications according to which the end of the supply pipe is provided with straight or inclined nozzles e, or with a conical plug f, Fig. 9 (Cancelled), connected to the pipe b by rods g or by a sleeve i or by both or if the supply pipe b projects upwards through the bottom of the mould it is provided with a perforated plug f. Fig. 10 (Cancelled). In another modification the supply pipe does not enter the mould and the plug f, Fig. 12 (Cancelled), is moved axially by a rod j. When casting from the top to the bottom the plug is made to fit the mould, as shown in Fig. 10 (Cancelled), but when it moves in the reverse direction it must be made smaller and then it determines the wall thickness of the pipe cast as shown in Fig. 12 (Cancelled). This subject-matter does not appear in the Specification as accepted.
