  • Patent number: 5414449
    Abstract: A process of thermal transfer printing which is accomplished in two printing steps. The process utilizes ribbon including a backing layer and an ink donor layer. The ribbon is drawn from a supply spool through a first printing station at which a first portion of the ink is transferred to the backing layer to form a first image thereon. The ribbon continues to and through a second printing station at which the remainder of the ink is transferred to a workpiece in the form of a second image which contrasts with the first image. All that remains of the ribbon as it leaves the second printing station is the backing layer which continues to and through the first printing station once again for the operation already mentioned. Thereupon, the ribbon is drawn onto a take-up spool for eventual disposal. The ink may be fluorescent.

  • Patent number: 5259878
    Abstract: An ink pad device for a high speed mailing machine is disclosed. The ink pad device includes an ink pad and an ink chamber in which the ink pad is at least partially disposed to sorb ink therefrom. The ink pad device may also comprise an ink reservoir and/or a pump for pumping ink from the reservoir to the ink chamber. The ink pad device is attachable to a drive for moving the ink pad horizontally and vertically from a horizontal home position to a horizontal inking position in which the ink pad is tamped against a printing device which imprints postage indicia. The ink pump comprises a deformable chamber which is compressed to pump ink from the reservoir to the ink chamber. In one embodiment, the ink pad and the ink chamber are provided as a disposable, non-replenishable, non-refillable unit containing a limited amount of ink for limited use. In another embodiment, the ink chamber, the ink pad, the reservoir and the pump form a unit in which ink is replenished from the reservoir to the ink chamber.

  • Patent number: 5056433
    Abstract: An ink tray has been improved to include a plurality of channel ribs formed on the bottom surface. The rib ends are spaced apart from the ink tray side walls. An ink pad is supported in the ink tray above the channels such that ink directed through the channels is absorbed by the ink pad. Replenishing ink is directed into the ink tray and caused to collect at one end of a first group of channel ribs and thereafter uniformly between each channel rib of the first group. The displaced ink is then caused to uniformly travel between a second group of channel ribs and exit the ink tray. The travel path of the ink allows for even absorption of ink by the ink pad and the removal of excess ink from the ink tray.

  • Patent number: 4579054
    Abstract: This invention relates to a stand-alone electronic mailing machine that includes a postage metering device. The invention has particular utility when utilized in a mailing machine of the reciprocating platen type. The entire drive mechanism, setting mechanism, and control devices as well as the postage metering mechanisms are all contained in one housing so that there is no need for a separate base. In the mailing machine of this invention, a single central processing unit is utilized along with memory for the purpose of accounting for the postage value that has been charged into the mailing machine as well as the amount that has been used. Non-volatile memory is provided for permanent storage in case of power failure. A pair of stepper motors is used for the purpose of adjusting the print dies with the amounts that are to be imprinted. One of the stepper motors is also used to trip a single revolution clutch which is utilized to affect the printing operation.
