Dependent Claim 19 words

Apparatus according to claim 4 in which the said axes are inclined to each other within the said plane.

Claim 7

Dependent Claim 80 words

Apparatus according to claim 1 in which the outlet means includes a chamber disposed in the path of material flowing from the inlet opening to said at least one outlet opening said chamber having a curved wall disposed in the path of granular material entering the outlet means through the inlet opening and arranged for guiding the granular material through a change of direction along said at least one flow path leading to the said at least one outlet opening.

Claim 8

Dependent Claim 31 words

Apparatus according to claim 6 in which the said curved wall is arranged to guide at least a proportion of the granular material through a change of direction greater than 90°.

Claim 9

Dependent Claim 196 words

Apparatus for injecting granular material in soil comprising: a frame for forward movement over the soil; a plurality of tines, said tines being carried by the said frame, each tine being adapted for opening a vertical slit in the soil when dragged through the soil by movement of the said frame; a plurality of conduits for delivering granular material, each tine having a conduit associated therewith for delivering granular material to the rear of the tine; and a plurality of outlet means, each tine having associated therewith an outlet means connected to the conduit of the tine, each outlet means defining at least one outlet opening for directing granular material in a direction rearwardly of the tine relative to said forward movement of said frame and predominantely in a vertically dispersed distribution including at least one of said at least one outlet openings oriented in an upward direction for providing an upwardly directed component, each outlet means including a swirl chamber operative to forcibly randomise the granular material immediately prior to its exit through said at least one outlet opening and for guiding granular material from the said conduit to said at least one outlet opening.

Claim 10

Dependent Claim 196 words

Apparatus for injecting granular material in soil comprising: a frame for forward movement over the soil; a plurality of tines, said tines being carried by the said frame, each tine being adapted for opening a vertical slit in the soil when dragged through the soil by movement of the said frame; a plurality of conduits for delivering granular material, each tine having a conduit associated therewith for delivering granular material to the rear of the tine; and a plurality of outlet means, each tine having associated therewith an outlet means connected to the conduit of the tine, each outlet means defining at least one outlet opening for directing granular material in a direction rearwardly of the tine relative to said forward movement of said frame and predominantely in a vertically dispersed distribution including at least one of said at least one outlet openings oriented in an upward direction for providing an upwardly directed component, each outlet means including a swirl chamber operative to forcibly randomise the granular material immediately prior to its exit through said at least one outlet opening and for guiding granular material from the said conduit to said at least one outlet opening.

Claim 11

Dependent Claim 32 words

Apparatus according to claim 1 in which each outlet means has a shape which defines a path for directing a proportion of the granular material upwardly in a direction inclined to horizontal.

Claim 12

Dependent Claim 21 words

Apparatus according to claim 8 in which each outlet means defines a plurality of openings spaced apart from each other vertically.

Claim 13

Dependent Claim 46 words

Apparatus according to claim 10 in which each opening defines an axis along which granular material is predominantly directed in operation, and the plurality of openings are disposed in such a manner that the axes of the openings all lie substantially in a single vertical plane.

Claim 14

Dependent Claim 43 words

Apparatus according to claim 11 in which at least one of the said openings has an axis inclined to the vertical in an upward direction and at least one of the openings has an axis inclined to the vertical in a downward direction.

Claim 15

Dependent Claim 19 words

Apparatus according to claim 10 in which the said plurality of openings are positioned substantially vertically one above another.

Claim 16

Dependent Claim 64 words

Apparatus according to claim 10 including an upper outlet opening for directing a proportion of granular material in an upward direction rearwardly of the tine, a lower outlet opening for directing a proportion of the granular material in a downward direction rearwardly of the tine, and a further outlet opening directed in a direction intermediate the directions of the upper and lower outlet openings.

Claim 17

Dependent Claim 67 words
