  • Patent number: 6969164
    Abstract: A printing cartridge including a body, the body having a base and a tower defining a passageway. The tower is made from a first polymer material, and has a proximal end and a distal end. The proximal end is attached to the base. The distal end includes a surface. A frame, made of a second polymer material different from the first polymer material, is attached to the surface of the tower. A filter is attached to the frame and positioned to extend over the passageway.

  • Publication number: 20040257412
    Abstract: A method of assembling a print head that includes the steps of: (a) providing a print head base including a nozzle and at least one ink channel; (b) mounting in fluid communication with the at least one ink channel of the print head base an ink regulator that includes: (i) a pressurized chamber including an ink inlet in fluid communication with an ink source, an ink outlet in fluid communication with the at least one ink channel of the print head base, and an exterior flexible wall having an inner surface facing an interior of the pressurized chamber, (ii) a valve biased to restrict fluid communication between the ink source and the pressurized chamber, where the exterior flexible wall actuates the valve to overcome the bias in response to a predetermined pressure differential across the exterior flexible wall to provide fluid communication between the ink source and the pressurized chamber, where the fluid communication between the pressurized chamber and the ink source decreases the pressure differential ac

  • Publication number: 20040257414
    Abstract: A method of assembling an ink filtration system in fluid communication with an ink source comprising the steps of: (a) providing a printhead base including at least one ink channel in fluid communication with at least one nozzle; (b) positioning an ink filter in fluid communication with at least the one ink channel of the printhead base; and (c) laser welding the ink filter in series with the printhead base to provide a sealed fluidic interface therebetween ensuring that ink within at least the one ink channel has passed through the ink filter. Also disclosed are methods and resulting apparatuses utilizing laser welding to mount components of an ink cartridge for use with an inkjet printer.

  • Patent number: 6164271
    Abstract: The ball throwing machine of this invention includes a vertical base plate mounting a wheel support plate for pivotal movement about a pivot axis which defines an arcuate slot in the base plate through which a clamp bolt extends from the wheel support plate. The wheel support plate mounts top and bottom pneumatic tired wheels for rotation to grip a ball between them and project it forward. An electrical control circuit affords adjustment of wheel rotational speed by a single rotary switch and also allows selection of a variety of types of pitches by a single rotary switch. The electrical circuit also provides for the setting of a differential rotational speed between the top and bottom wheels, for optimum quality of pitching control, and also provides for limiting the minimum and maximum wheel rotating speeds to achieve realistic pitching speed range.

  • Patent number: 6089217
    Abstract: A ball throwing machine which includes a tripod leg support is provided with the rearwardly positioned leg formed as a pair of telescopic sections. Rack and pinion components are mounted one on each leg section and the pinion is operated by a crank to effect lengthening or shortening the telescopic sections, to effect an incremental change in the trajectory of a ball thrown by the machine.

  • Patent number: 4604798
    Abstract: Apparatus for removal of connectors from printed circuit boards. The connors have spring-lock type of conductor pins therein which secure the connectors to the printed circuit board in substantially permanent relation and if some conductor pins were to become defective the whole printed circuit board would be thrown away. The device of the present invention is disposed for removal of the connectors from the printed circuit board without causing damage to the board.
