Abstract
Abstract A control assembly for use in controlling the operation of a can end press of the type having a plurality of operating stations for performing different work operations on a can end passing through the press, each operating station including a fixed station portion and a reciprocally movable station portion which engages a can end mounted on the fixed station portion, comprising: strain gauge operatively associated with at least one of the operating stations for detecting the strain experienced in a portion of the station during press operation and for providing a strain gauge signal indicative thereof; data processing assembly for receiving and processing the signal of the strain gauge for detecting a signal condition conforming to predetermined criteria associated with an abnormal operating state of the press and for providing a control signal responsive to the detected abnormal operating state.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
217 words
A method for modifying a lower base member of a progressive press station for enabling accurate load sensing in the press station wherein an unmodified lower base member comprises a generally cylindrical tool supporting, upper portion and comprises a lower attachment plate portion integrally formed with said upper cylindrical portion which is adapted for mounting said lower base member on a lower press shoe, said lower attachment plate portion having a lower base dowel pin bore extending therethrough in coaxial relationship with a central longitudinal axis of said upper cylindrical portion; said lower base member being located on said lower press shoe by an original dowel pin received in said lower base dowel pin bore and in an oppositely positioned dowel pin bore in said lower press shoe, the method comprising the steps of: a) radially and axially enlarging said lower base dowel pin bore whereby said enlarged bore extends axially into said generally cylindrical portion of said lower base member; b) machiningly reducing the diameter of said upper cylindrical portion of said lower base member in an axial region thereof positioned radially opposite a portion of said enlarged dowel pin bore; and c) mounting a transducer on an axially extending surface of said upper cylindrical portion of said lower base member in said axial region thereof
Claim 2
Independent Claim

Claim 3
Dependent Claim
49 words
The method of claim 1 wherein the steps of enlarging said dowel pin bore and machiningly reducing said upper cylindrical portion diameter comprises reducing the cross sectional area of said upper cylindrical portion in a selected axial region thereof to less than half of its original cross sectional area.
Claim 4
Dependent Claim
20 words
The method of claim 2 wherein said reduced cross sectional area is approximately 46% of the original cross sectional area.
Claim 5
Dependent Claim
33 words
The method of claim 1 comprising the further step of providing a radial bore through said upper cylindrical portion of said base member and extending a lead wire from said transducer assembly therethrough
Claim 6
Dependent Claim
93 words
The method of claim 1 comprising the further steps of: a) substituting a modified dowel pin for said original dowel pin; said modified dowel pin having a lower portion identical in diameter to the original dowel pin, a midportion having a diameter slightly less than the diameter of said expanded dowel pin bore in the base member, and an upper portion having a diameter less than said midportion diameter; and b) mounting said modified dowel pin in non-load-bearing relationship in said dowel pin bores in said base member and said lower die shoe.
Claim 7
Dependent Claim
25 words
The method of claim 1, said transducer mounting step comprising mounting a transducer assembly on an outer reduced diameter surface of said upper cylindrical portion
Claim 8
Dependent Claim
27 words
The method of claim 6 comprising the step of covering the reduced diameter region of the upper cylindrical portion and the transducer assembly mounted thereon with epoxy.
Claim 9
Dependent Claim
175 words
The method of claim 1: a) wherein the steps of enlarging said dowel pin bore and machiningly reducing said upper cylindrical portion diameter comprises reducing the cross sectional area of said upper cylindrical portion in a selected axial region thereof by at least 50%; b) wherein said transducer mounting step comprising mounting a transducer assembly on an outer reduced diameter surface of said upper cylindrical portion; c) and comprising the further steps of: i) substituting a modified dowel pin for said original dowel pin; said modified dowel pin having a lower portion identical in diameter to the original dowel pin, a midportion having a diameter slightly less than the diameter of said expanded dowel pin bore in the base member and an upper portion having a diameter less than said midportion diameter; ii) mounting said modified dowel pin in non-load-bearing relationship in said dowel pin bores in said base member and said lower die shoe; and iii) covering the reduced diameter region of the upper cylindrical portion and the transducer assembly mounted thereon with epoxy.
Claim 10
Independent Claim
63 words
A method for mounting a transducer assembly on a cylindrical portion of a base member of a progressive can end press comprising the steps of: a) providing a circumferential recess in a selected axial region of the cylindrical portion; b) mounting a transducer assembly on the base member in the circumferential recess; and c) filling the circumferential recess with a sealing matrix material.
Claim 11
Independent Claim
63 words
A method for mounting a transducer assembly on a cylindrical portion of a base member of a progressive can end press comprising the steps of: a) providing a circumferential recess in a selected axial region of the cylindrical portion; b) mounting a transducer assembly on the base member in the circumferential recess; and c) filling the circumferential recess with a sealing matrix material.
