Abstract

A liquid fuel conditioning device comprises a pellet of a metallic alloy wrapped in mesh formed from a ferrous material. Alloy contains e.g. tin. Device is obtained by positioning the pellet on a blank mesh e.g. of mild steel, then deforming the blank to enclose the pellet.

Description

METHOD OF MANUFACTURE This invention relates to a liquid fuel conditioning device of the kind comprising a pellet of a metallic alloy composed largely of tin, which in the use of the device is immersed in the fuel to be conditioned.
Such devices are well known in the art and in order to be effective the surface of the pellet should be in contact with a ferrous material. It is known to locate two or more pellets in an elongated envelope formed from a ferrous mesh material however, one disadvantage with this arrangement is that different sizes of envelope are required depending on the number of pellets in the device. Furthermore it is difficult to obtain good contact between the mesh and the surfaces of the pellet. Moreover, when wrapped in an envelope the devices are generally only suitable for placing in a fuel tank. The pellets are manufactured by gravity casting the alloy into depressions in a mould with the result that the pellet has a generally flat surface and a further surface or surfaces corresponding to that of the mould depression. Conveniently the further surface is of a curved nature.
In order to improve the effectiveness of the device and also to simplify its manufacture, it is proposed to wrap each pellet individually in a ferrous mesh and in the accompanying drawings: Figure 1-4 illustrate in sequence one way of wrapping the pellet, and Figure 5 shows in section an arrangement of a fuel conditioning unit incorporating a number of the wrapped pellets.
With reference to Figures 1-4, the pellet which is indicated at 10 in Figures 3 and 4, is wrapped by first stamping out from mild steel mesh, a star shaped blank 11 seen in Figure 1. The blank is then deformed using a suitable press tool, into the form of a cup 12 as shown in Figure 2 following which the pellet 10 is placed in the cup with the flat surface of the pellet in contact with the base wall of the cup. The upper edges of the cup are then deformed over the curved surface of the pellet using a suitable forming tool as shown in Figure 4.
In the manner described, the pellet 10 is enclosed by the mild steel mesh and both the flat and curved surfaces of the pellet are in firm engagement with the mesh thus ensuring the maximum performance of the device in use.
Figure 5 shows a conditioning unit 13 for incorporation in a fuel supply line to an engine. The unit comprises a tube 14 conveniently formed from brass and having end closures 15 which are provided with tapped holed for the reception of pipe fittings. Located within the tube is a plurality of the wrapped pellets and also a pair of ferrite bar magnets. In the use of the unit fuel passes through the tube and is conditioned by the action of the wrapped pellets and the magnetic field produced by the magnets.
The number of wrapped pellets which will be required depends upon the size of the engine to which fuel is being supplied. As the capacity of the engine increases the number of wrapped pellets must also be increased and hence the length of the tube must be adjusted accordingly. In the case of diesel engines besides the conditioning unit illustrated in Figure 5, it may be necessary to place a number of the wrapped pellets in the fuel storage tank.

Claims (7)
