Abstract
Abstract A system for directing operation of the individual sections of a glass container making machine for initiating and discontinuing section operation at preestablished times in the machine operating cycle and, upon demand, at other times in said cycle. Storage means containing a preestablished cam is associated with each section and section operation is initiated and discontinued in accordance with the cam, the time characteristics of the cam being modified by a cam-trimming system upon said demand.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
205 words
A system directing an I.S. machine individual section to operate in predetermined time relation within the machine cycle or in modified time relation therein upon demand indicated by control inputs comprising: a. storage means containing magnetic signals arranged in said predetermined time relation; b. an electrical signal generator providing output signals corresponding to magnetic signals contained in said storage means; c. a section controller receiving said signal generator output signals and operating said section during occurrence thereof; d. trimming means receiving said signal generator output signals and said control inputs and generating electrical output signals having time relation to said signal generator output signals for conforming said contained magnetic signals to said modified time relation defined by said control inputs; and e. a magnetic signal generator receiving said trimming means output signals and applying corresponding magnetic signals to said storage means thereby conforming said contained magnetic signals to said modified time relation. 2. The system claimed in claim 1 wherein said storage means comprise a magnetic storage drum rotated in synchronism with the conveyor driVe means of said machine, said contained magnetic signals being stored in a continuous portion of said drum periphery and defining a cam having said predetermined relation to said machine cycle.
Claim 2
Dependent Claim
61 words
The system claimed in claim 2 wherein said electrical signal generator output signals include a first signal time coincident with the leading edge of said cam and a second signal time coincident with the trailing edge of said cam, said section controller initiating section operation immediately upon receiving said first signal and discontinuing section operation immediately upon receiving said second signal.
Claim 3
Dependent Claim
47 words
The system claimed in claim 3 wherein said section controller includes a solenoid energized by said first signal and deenergized immediately upon receiving of said second signal, and a valve operated by said solenoid and conducting compressed air to said machine section during energization of said solenoid.
Claim 4
Dependent Claim
126 words
The system claimed in claim 3 wherein said control inputs indicate demands for time advancement of said cam leading edge or for time retardation of said cam trailing edge, magnetic signals being written in said storage means by first polarity electrical signals applied to said magnetic signal generator, said trimming means generating first polarity output signals in response to said control inputs. 6. The system claimed in claim 3 wherein said control inputs indicate demands for time retardation of said cam leading edge or for time advancement of said cam trailing edge, contained magnetic signals being erased from said storage means by second polarity electrical signals applied to said magnetic signal generator, said trimming means generating second polarity output signals in response to said control inputs.
Claim 5
Independent Claim
225 words
A system providing signals initiating and discontinuing the the operation of an I.S. machine section controller during a machine-operating cycle and varying the time of occurrence of said signals in said cycle in response to control signals requiring time advancement or time retardation in said cycle of either said initiation or discontinuance comprising: a. storage means rotated in synchronism with the conveyor drive means of said machine and containing a continuous magnetic cam; b. a first signal generator fixedly positioned with respect to said storage means and generating electrical output signals corresponding to said cam, including signals respectively indicative of the leading edge and the trailing edge of said cam, said leading edge signal constituting said operation-initiating signal and said trailing edge signal constituting said operation-discontinuing signal; c. cam-trimming means connected to said machine conveyor drive means and receiving said first signal generator output signals and said control signals and operatively responsive thereto to generate electrical output signals for advancement or retardation of said cam leading edge or said cam trailing edge; and d. a second signal generator fixedly positioned with respect to said storage means and spaced in the direction of rotation thereof from said first transducer, said second signal generator receiving said cam-trimming means output signals and generating corresponding magnetic signals advancing or retarding said cam leading edge or said cam trailing edge.
Claim 6
Independent Claim
225 words
A system providing signals initiating and discontinuing the the operation of an I.S. machine section controller during a machine-operating cycle and varying the time of occurrence of said signals in said cycle in response to control signals requiring time advancement or time retardation in said cycle of either said initiation or discontinuance comprising: a. storage means rotated in synchronism with the conveyor drive means of said machine and containing a continuous magnetic cam; b. a first signal generator fixedly positioned with respect to said storage means and generating electrical output signals corresponding to said cam, including signals respectively indicative of the leading edge and the trailing edge of said cam, said leading edge signal constituting said operation-initiating signal and said trailing edge signal constituting said operation-discontinuing signal; c. cam-trimming means connected to said machine conveyor drive means and receiving said first signal generator output signals and said control signals and operatively responsive thereto to generate electrical output signals for advancement or retardation of said cam leading edge or said cam trailing edge; and d. a second signal generator fixedly positioned with respect to said storage means and spaced in the direction of rotation thereof from said first transducer, said second signal generator receiving said cam-trimming means output signals and generating corresponding magnetic signals advancing or retarding said cam leading edge or said cam trailing edge.
Claim 7
Dependent Claim
109 words
The system claimed in claim 7 wherein said cam-trimming means comprises: a. first means operatively responsive to said control signal to selectively regenerate either said cam leading edge signal or said cam trailing edge signal; b. second means operatively responsive to said first means output signal and to said machine conveyor drive means to generate signals indicative of the angular position of said first means selected contained cam edge with respect to said second transducer; and c. third means operatively responsive to said control signals and to said second means output signals to generate said signals for advancement or retardation of said cam edge selected by said first meanS.
