  • Patent number: 5429698
    Abstract: Methods and apparatus for printing and collating multiple webs of materials, particularly for use in creating personalized direct mail materials, are disclosed. The invention includes a single, highly flexible press having components capable of being driven at unequal speeds to account for different sizes of insert materials and their associated envelopes. Operating a single press in this manner reduces the amount of waste web material which otherwise would be present. The press similarly includes novel collating and inserting apparatus whereby each outgoing envelope is effectively formed around the "insertable" materials. Control mechanisms and verification systems associated with the press additionally maintain any personalized materials in registration, permitting a single press to produce the entire direct mail piece from multiple webs with minimal waste.
    Type: Grant

  • Patent number: 4108182
    Abstract: A surgical instrument comprising a housing with a motor and source of power contained in the housing. A removable sheath is placed over the housing and a cutter assembly is removably mounted to the housing so that the housing is protected from external materials and contamination. The cutter assembly has a body, a tube projecting from the body, a reciprocating blade positioned in the tube and a cam drive transfer mechanism mounted in the cutter body which transmits motion to the blade from the motor shaft. The tube defines an aperture in its side and the blade as it reciprocates in combination with the walls defining the aperture shears vitreous material entering the hole. A second passage is formed in the cutter body communicating with the tube to allow pressure differentials to be exerted to the tube.The cutter head and removable protective sheath are replaced after each successive operation in order to eliminate patient-to-patient cross contamination.
