摘要:
A method and apparatus for priming a printhead. The method includes the steps of bringing a vacuum pump up to a predetermined speed and sealingly engaging a printhead with a capping mechanism after the pump reaches the predetermined speed. The pump is connected to the capping mechanism through a tube with a suitable volume. After a period of time long enough to prime the printhead, the capping mechanism is disengaged from the printhead.

A positionable wiper blade is positioned by a translatable carriage contact and clean a printhead nozzle face. The carriage translates a removable ink tank support structure with an attached ink jet printhead from a printing location to a non-printing location where the positionable wiper blade is located. A replaceable ink supply tank is installed on the support structure and replaced when the ink is depleted. The wiper blade is moved into wiping position by movement of the carriage and when the carriage is translated away from the non-printing location towards the printing location, the wiper blade cleans the printhead nozzle face and flicks the ink removed from the nozzle face into a backstop receptacle. Continued translation by the carriage moves the wiper blade into contact with the backstop receptacle, which then cleans the wiper blade, and subsequently positions the wiper blade away from the wiping position when the carriage returns to the non-printing location, so that the wiper blade does not contact the backstop receptacle until after it cleans the printhead nozzle face.
摘要:
A priming system for selectively priming one of the two printheads of a multicolor ink jet printer. When one of the printheads require periodic priming, the printheads are transported to the printer's maintenance station where individual caps are moved to cover the nozzle faces of the printheads. The priming system has two individual peristaltic pumps, each one of which is connected to a respective one of the caps. The two peristaltic pumps have a single mechanical input to drive selectively one of the pumps and not the other by a positionable swing gear. Each one of the pumps is adapted to prime only one of the printheads. The swing gear engages the drive gear of one pump when the direction of rotation of the input is clockwise and the swing gear engages the drive gear of the other pump when the direction of rotation of the input is counterclockwise.

A method authorizes the holder of a film unit to access a look-up table having stored data The film unit bears an access code having an encrypted first segment. In the method, the film unit is registered and the first segment is detected. The first segment is decrypted to obtain a code value. The code value is matched to a second segment and access to the stored data is allowed.

A method is provided for storing information related to a photographic film unit that includes a local data memory such as magnetic media or an electronic memory unit. In the method, a logical memory unit and the film unit are associated. The logical memory unit is physically remote from the film unit. Exposure-independent information for the film unit is written to the logical memory unit. Exposure-dependent information is written to the local data memory.

A one-time-use camera comprising a film winder wheel rotatable in a film winding direction and a rear cover part with an integral door portion that is to be opened to remove a film cartridge from a cartridge chamber, an integral anti-backup pawl for engaging the film winder wheel to prevent rotation of the film winder wheel in a reverse direction opposite to the film winding direction, and a weakened longitudinal section between the door portion and another portion of the rear cover part that fractures when the door portion is opened, is characterized in that the anti-backup pawl and the door portion are connected to cause the anti-backup pawl to be moved with the door portion when the door portion is opened, and the weakened longitudinal section extends between the anti-backup pawl and the other portion of the rear cover part to fracture between the anti-backup pawl and the other portion, in addition to fracturing between the door portion and the other portion, when the door portion is opened, whereby the anti-backup pawl will be renedered ineffective to prevent reverse rotation of the film winder wheel.
摘要:
A formulation of a drug in a liquid carrier is heated in a controlled fashion and then aerosolized. The aerosolized formulation comprises particles having an aerodynamic diameter in a range of about 0.5 to about 12 micrometers. The particles are inhaled into the lungs of a human patient thereby delivering drug to the patient. By heating the formulation prior to aerosolization, the viscosity of the formulation is reduced thereby improving delivery efficiency. Repeatability of aerosol formation is improved by pre-heating the solution to the same or substantially the same temperature for successive delivery events.
摘要:
In a method for associating a film unit and a one-time use camera, a first copy of a unique identifier is recorded on the film unit. A logical memory unit and the identifier are associated. The logical memory unit is physically remote from the film unit. The film unit is loaded in the one-time use camera body. A second copy of the unique identifier is recorded on the one-time use camera body. The second copy is accessible independent of the film unit.
摘要:
A method keeps photographic film current. In the method, a logical memory unit is allocated to the photographic film unit. The logical memory unit is remote from the film unit. A plurality of photofinishing parameters for the film unit are designated. The logical memory unit is maintained for a time period sufficient to cause aging. The photofinishing parameters are updated counteractive to the aging and photofinishing can then be performed using the updated parameters for the film unit.
摘要:
A one-time-use camera comprising a main body part, a cover part that can be separated at least partially from the main body part, and a viewfinder having a pair of front and rear viewing lenses optically aligned for viewing a subject to be photographed, is characterized in that the cover part is connected to one of the front and rear viewing lenses to move the one viewing lens out of optical alignment with the other viewing lens when the cover part is separated at least partially from the main body part, whereby the one viewing lens can be readily identified to prevent the viewfinder from being erroneously reused. Preferably, the one viewing lens is connected to the main body part in addition to being connected to the cover part in order to hold the cover part to the main body part. A fracture line of weakness exists between the one viewing lens and the main body part which is broken when the one viewing lens is moved out of optical alignment with the other viewing lens.
