专利汇可以提供Electronic control system for adjustment of ink fountain in a printing press专利检索，专利查询，专利分析的服务。并且An electronic system for adjusting the ink fountain in a printing press. The ink fountain includes a plurality of adjusting screws driven by a motor through a drive shaft which is clutched and declutched to the screws by means of a solenoid matrix. Energization of selected solenoids within the matrix is controlled by pushbuttons on a unit control panel. A first series of buttons is used to select the plate position at which the adjustment is to be effected, and a second series of pushbuttons is used to select the column position at which the adjustment is to be effected. A pair of separate unit control panels is provided at each printing unit in the press. A digital counter provides a visible indication of the magnitude of each adjustment commanded by the operator. The system may be used for presetting the press, as well as making adjustments during a press run. A color cylinder or half deck on the unit may be controlled through the same control panel used to control the balance of the unit.，下面是Electronic control system for adjustment of ink fountain in a printing press专利的具体信息内容。

权利要求

1. In an electrical ink control system for a printing press having a printing cylinder, a plurality of plate positions along the printing cylinder, a plurality of repeated columnar positions along each plate position, and control means for each columnar position along the printing cylinder to regulate the flow of ink from an ink supply to the respective columnar position, the improvement comprising: means including a first manually-operated momentary enabling switch for each plate position along the printing cylinder for selecting the plate position at which ink regulation is to be effected; means including a first manually-operated momentary activating switch for each repeated columnar position along a plate position for selecting the column position at which ink regulation is to be effected; first matrix circuit means for selectively connecting each different combination comprised of one of said first momentary enabling switch means and one of said first momentary activating switch means in controlling relation to a different one of said ink flow regulating control means; means including a first pulse activated bi-stable latch for connecting each of said first manually-operated momentary enabling switch means to said first matrix circuit means in enabling relation to all of said first manually-operated momentary activating switch means; means for producing a pulse signal by manual operation of any selected one of said first enabling switch means to selectively set a respective one of said first bi-stable latch means in enabling relationship to all of said first activating switch means; and means generating a shorter duration pulse signal by the operation of any other of said first enabling switch means to reset said selected first bi-stable latch means in a disabled relationship to all of said first activating switch means.

2. The invention defined by claim 1 in combination with a printing press having an additional printing cylinder and corresponding plate positions, repeated columnar positions, and ink flow regulating control means, further comprising: means including a second manually - operated momentary enabling switch for each plate position along the said additional printing cylinder for selecting the plate position at which ink regulation is to be effected; means including a second manually - operated momentary activating switch for each repeated columnar position along the said additional corresponding plate position for selecting the column position at which ink regulation is to be effected; second matrix circuit means for selectively connecting each different combination comprised of one of said second momentary enabling switch means and one of said second momentary activating switch means in controlling relation to a different one of said additional ink flow regulating control means; means including a second pulse activated bi-stable latch for connecting each of said second manually-operated momentary enabling switch means to said second matrix circuit means in enabling relation to all of said second manually-operated momentary activating switch means; means for producing a pulse signal by manual operation of any selected one of said second enabling switch means to selectively set a respective one of said second bi-stable latch means in enabling relationship to all of said second activating switch means; and means generating a shorter duration pulse signal by the operation of any other of said first and second enabling switch means to reset said selected second bi-stable latch means in a disabled relationship to all of said second activating switch means.

3. The invention defined by claim 2 wherein each said first bi-stable latch means also is reset by a shorter duration pulse signal generated by operation of any of said second manually-operated momentary enabling switch means.
