Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
91 words
A food processing apparatus comprising an extruder having an outlet, a nozzle connected to said outlet for discharging extrudate, an extrudate receiver located to receive extrudate from said nozzle, mounting means mounting said nozzle and receiver for universal relative motion in two axes to discharge extrudate in any preselected configuration on said receiver positioning means in driving relation with said mounting means for selectively effecting said universal relative motion. programmable controller means for selectively and variably controlling said positioning means to effect continuous or discontinuous relative motion of said mounting means.
Claim 2
Dependent Claim
91 words
A food processing apparatus comprising an extruder having an outlet, a nozzle connected to said outlet for discharging extrudate, an extrudate receiver located to receive extrudate from said nozzle, mounting means mounting said nozzle and receiver for universal relative motion in two axes to discharge extrudate in any preselected configuration on said receiver positioning means in driving relation with said mounting means for selectively effecting said universal relative motion. programmable controller means for selectively and variably controlling said positioning means to effect continuous or discontinuous relative motion of said mounting means.
Claim 3
Dependent Claim
45 words
A food processing apparatus according to claim 1, in combination with a valve associated with said nozzle for selectively starting and stopping extrudate, and valve operating means synchronized with said controller means for opening and closing said valve in selected relation with said relative motion.
Claim 4
Dependent Claim
45 words
A food processing apparatus according to claim 1, said nozzle comprising a flexible conduit having one end communicating with said extruder outlet, and an orifice on the other end of said conduit for discharging extrudate, said mounting means mounting said orifice for said relative motion.
Claim 5
Dependent Claim
50 words
A food processing apparatus according to claim 1, in combination with an additional nozzle communicating with said outlet for discharging an additional stream of extrudate to said receiver, said mounting means mounting said first mentioned and additional nozzles for discharging plural extrudate streams in a preselected configuration on said receiver.
Claim 6
Dependent Claim
38 words
A food processing apparatus according to claim 3, said receiver comprising a conveyor movable along one axis of said relative motion, said controller means controlling said relative motion along said one axis to accomodate to said conveyor movement.
Claim 7
Dependent Claim
53 words
A food processing apparatus according to claim 5, in combination with a valve associated with said nozzle for selectively starting and stopping extrudate, and valve operating means synchronized with said controller means for opening and closing said valve in selected relation with said relative motion to stop extrudate upon completion of said configuration.
Claim 8
Dependent Claim
52 words
A food processing apparatus according to claim 1, said receiver comprising a generally upwardly facing conveyor, said nozzle being over and facing downwardly toward said conveyor, and said mounting means mounting said nozzle for movement longitudinally along and transversely of said conveyor, for discharging extrudate having a two dimensional preselected line configuration.
Claim 9
Dependent Claim
77 words
A food processing apparatus according to claim 7, said conveyor comprising an elongate longitudinally moving belt, said mounting means comprising a longitudinal trolley movable in opposite directions longitudinally along said belt, and a transverse trolley movable with said longitudinal trolley and relative thereto in opposite directions transversely of said belt, said nozzle being carried by said transverse trolley for longitudinal movement with said longitudinal trolley and transverse movement with said transverse trolley relative to said longitudinal trolley.
Claim 10
Dependent Claim
75 words
A food processing apparatus according to claim 8, said positioning means comprising longitudinal and transverse drive means respectively in driving relation with said longitudinal and transverse trolleys, and said controller mean comprising a data processor operatively connected in controlling relation with said longitudinal and transverse drive means, and a memory connected to said processor for imparting information to said processor for operating said drive means to produce said preselected configuration of extrudate on said receiver.
Claim 11
Dependent Claim
48 words
A food processing apparatus according to claim 9, in combination with longitudinal way means fixed along said conveyor and supporting said longitudinal trolley for longitudinal movement, and transverse way means fixed on said longitudinal trolley and supporting said transverse trolley for transverse movement relative to said longitudinal trolley.
Claim 12
Dependent Claim
82 words
A food processing apparatus according to claim 10, said longitudinal drive means comprising a longitudinally extending rotary lead screw operatively connected to said longitudinal trolley, a longitudinal drive motor connected in driving relation with said longitudinally extending lead screw, a transversely extending rotary lead screw operatively connected to said transverse trolley, and a transverse drive motor connected in driving relation with said transversely extending lead screw, said longitudinal and transverse drive motors being electrically connected to said data processor for control thereby.
Claim 13
Dependent Claim
53 words
A food processing apparatus according to claim 11, in combination with a valve associated with said nozzle for selectively starting and stopping extrudate, and valve operating means electrically connected to said data processor for opening and closing said valve in selected relation with nozzle movement to stop extrudate upon completion of said configuration.
Claim 14
Dependent Claim
91 words
A food processing apparatus according to claim 1, in combination with a discharge orifice on said nozzle for passing extrudate, and a closure valve at said discharge orifice for selectively starting and stopping extrudate upon opening and closing for terminating extrudate flow at the discharge orifice, said receiver comprising a generally upwardly facing conveyor moveable in the direction of one dimension of said relative motion, said conveyor being under and closely beneath said nozzle, whereby said valve upon closure severs extrudate proximate to said receiver for accurately terminating the extrudate configuration.
