摘要:
Apparatus, systems and methods for use in three-dimensional printing are shown and described. Various embodiments of the invention allow for more precise and controlled delivery of heat to achieve interlayer drying; isolation of the working region from the outside for reasons of cleanliness and in connection with the vapors of organic solvents; better control of the temperature of the working region; better accuracy in the flowrates of binder fluid dispensed; matching of delivered flowrates for multiple dispensers; verification of delivered flowrate or drops; provision for easier changeover of the machine from one powder to another; cleanability; and other needs.

The rapid design and manufacture of biomedical devices such as implants, oral dosage pills and implantable pharmaceuticals employs electronic data and modeling transmissions via a computer network. Patient information and patient-specific radiological data is captured and transmitted via a computer network to a design and/or manufacturing site. A multi-dimensional digital model is created based on the radiological data and patient information. Communications interchanges between a clinical/diagnostic site and a design/manufacturing site permit modification of the digital model until approved. The approved digital model is converted into machine instructions to construct the biomedical device. Alternatively, the digital model is employed in a best fit selection of a biomedical device from a pre-existing set of biomedical devices or machine-instructions. Transmittal of data over computer networks is further directed to the use of a Website to perform various client-interaction and follow-up tasks.

An apparatus includes a printer and a buffer coupled to the printer for temporarily storing sheets fed out from the printer. The apparatus further includes a control mechanism for monitoring the buffer to determine a number of sheets currently stored in the buffer. The apparatus also includes a data source device that is separate from the printer and is coupled to the printer for selectively providing pages of print data to the printer. The data source device is coupled to the control mechanism and is operative to provide the pages of print data to the printer in response to control signals from the control mechanism.

A method for coding the address location on a document or in a data base so that two or more electronic mailings with differing address placements may be combined together and sorted while the mailings are still in electronic form in order to take advantage of workshare discounts, delivery sequence efficiency, desired delivery date, class of delivery service, etc.

In a mail inserter having an envelope movement mechanism to move an envelope into an insertion station and a feeder to move a pack of insert material into an insertion position so that the insert material can be inserted into the envelope, a linear array of optical sensing elements is used to determine the position of one edge of the insert material and another linear array of optical sensing elements is used to determine the position of one edge of the receiving envelope in order to make sure that there is sufficient end clearance between the insert material and the receiving envelope. A stepper motor is used to adjust the envelope position, if the end clearance is outside a predetermined range.
摘要:
A method and a system are disclosed for adaptively controlling a stepper motor to produce a required torque output based on selection information provided by a sensor or a user/user interface which, in combination with a selector, selects a torque-related value. The selection information provided to the selector for selecting the stepper motor torque-related value may be, for example, the size or thickness of material being handled or the number of accumulated sheets for processing. The torque-related value is predetermined through experimentation and loaded into a lookup table stored in the memory of a motion control system board. The selected torque-related value is provided to a stepper motor driver which supplies the appropriate drive signal(s) to the stepper motor.

The sheet capacity of a pivoting feed head is combined with a complimentary pivoting design for the paper tray lift, such that a large total capacity of sheets is attained within a compact space, while allowing the lifting mechanisms to be located outside of the perimeter of the paper tray.

A feeder for feeding media items from a tray includes a first nudger roller and a second nudger roller. The first and the second nudger roller are moveably mounted to the feeder. The first and the second nudger rollers are in a first position when a tray of a first type is connected to said feeder the first and said second nudger rollers are in a second position when a tray of a second type is connected to said feeder. The tray of a first type may be a shingle feed tray and the tray of a second type may be a stacks feed tray. With the shingle feed tray the first position for the first and the second nudger rollers are where each nudger roller engages each media item in a shingles tray when each such media item is positioned in the shingles tray to exit the shingles tray and to be moved from the shingles tray into said feeder. With the stacks feed tray the second position for the first and the second nudger rollers are where the first nudger roller is positioned out of engagement with media items in a stacks tray and the second nudger rollers is positioned to each engage each media item in the stacks tray when each such media item is positioned in said stacks tray to exit the stacks tray and to be moved from the stacks tray into said feeder.
摘要:
A method and apparatus for folding inserts by inverting the insert sheet after the first fold is made and reintroducing the folded insert sheet into a first buckle chute from the opposite end. The second fold is then made in a second buckle chute which results in either a bottom address or a middle address appearing on the folded insert in a manner that the address will appear through the window of the envelope.
摘要:
An ingestion assembly is provided for a singulating apparatus having a conveyor system for moving a stack of sheet material along a feed path. The ingestion assembly is spatially positioned above the conveyor belt and includes at least one singulating roller driven in a direction opposing the motion of the conveyor belt. The ingestion assembly comprises an assembly support rotationally mounting the singulating roller at a downstream end portion and pivotally mounting to the singulating apparatus at an upstream end portion. A movable guide mounts to the assembly support and is positionable relative thereto as a function of a force vector imposed on the guide by the sheet material. Additionally, the moveable guide includes a surface operative to guide the sheet material into a singulating interface which is formed between the singulating roller and the conveyor system. In operation, sheet material enters the throat of the ingestion assembly and contact is made with the moveable guide. When the force vector, imposed by the sheet material, is less than a threshold level, the guide assumes a first position operative to shingle sheet material in preparation for singulation by the singulating roller. When the force vector, is greater than the threshold level, movable guide assumes a second position operative to pivot the assembly support and increase the singulating interface. Consequently, sheet material having a larger thickness dimension may pass for separation by the singulation apparatus.
