Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
107 words
A method for enhancing the scaling of stiff dough comprising: degassing and positively feeding stiff dough from an open feed hopper by moving said dough between two rotating feed rolls, through a closed pressure retaining hopper and to a rotating scaling drum having plural through cylinders and a double-acting piston in each of said cylinders, sensing pressure in said closed hopper and controlling pressure in said closed hopper by varying the rotation speed of said two rolls in response to the sensed pressure in said closed hopper and maintaining the minimum pressure in said closed hopper necessary to keep said dough in contact with said scaling drum.
Claim 2
Independent Claim
107 words
A method for enhancing the scaling of stiff dough comprising: degassing and positively feeding stiff dough from an open feed hopper by moving said dough between two rotating feed rolls, through a closed pressure retaining hopper and to a rotating scaling drum having plural through cylinders and a double-acting piston in each of said cylinders, sensing pressure in said closed hopper and controlling pressure in said closed hopper by varying the rotation speed of said two rolls in response to the sensed pressure in said closed hopper and maintaining the minimum pressure in said closed hopper necessary to keep said dough in contact with said scaling drum.
Claim 3
Dependent Claim
23 words
The method in accordance with claim 1, including automatically controlling the positive feed rate of the dough in accordance with the scaling rate.
Claim 4
Dependent Claim
37 words
The method in accordance with claim 1, including maintaining the positively fed dough at a pressure within a predetermined range; sensing the pressure; and automatically varying the positive feed rate in response to changes of sensed pressure.
Claim 5
Dependent Claim
100 words
Dough scaling apparatus comprising: an open feed hopper above two spaced rotatable positive feed rolls for mildly degassing and feeding stiff dough, a closed hopper means beneath said feed rolls, said closed hopper means providing a pressure retaining enclosure in cooperation with said drum and said rolls, pressure sensing means in communicating relationship with the interior of said closed hopper means, control means connected with said pressure sensing means and connected with drive means for said two feed rolls and suitable for controlling the rotational speed of said two rolls in response to the sensed pressure in said closed hopper.
Claim 6
Dependent Claim
100 words
Dough scaling apparatus comprising: an open feed hopper above two spaced rotatable positive feed rolls for mildly degassing and feeding stiff dough, a closed hopper means beneath said feed rolls, said closed hopper means providing a pressure retaining enclosure in cooperation with said drum and said rolls, pressure sensing means in communicating relationship with the interior of said closed hopper means, control means connected with said pressure sensing means and connected with drive means for said two feed rolls and suitable for controlling the rotational speed of said two rolls in response to the sensed pressure in said closed hopper.
Claim 7
Dependent Claim
27 words
The enhancing means in accordance with claim 4, including means for automatically controlling the feed rate of said positive feed means in accordance with the scaling rate.
Claim 8
Dependent Claim
49 words
The enhancing means in accordance with claim 4, including means for sensing pressure within said hopper means with positively fed dough; means for establishing an acceptable level of pressure; and means for automatically varying the feed rate of said positive feed means in response to changes in sensed pressure.
Claim 9
Dependent Claim
64 words
The enhancing means in accordance with claim 4, wherein said means mildly degassing and positively feeding dough comprising a pair of rollers rotating oppositely to one another forming the bottom of said funnel hopper and being disposed in spaced face to face relationship with the space therebetween defining the funnel hopper discharge to said feed hopper; and motor means for rotatably driving said rollers.
Claim 10
Dependent Claim
45 words
The enhancing means in accordance with claim 7, including means for establishing an acceptable level of pressure, and means connected to both of said means and said motor means for varying the speed of said rollers in response to differences between sensed and acceptable pressures.
