Abstract: Safety contrivance for bag sealer is provided, including a pair of specially designed terminal brackets mounted on opposite ends of an upper jaw of the bag sealer. The terminal bracket has an angular slot, including a vertical and a horizontal slot sections, right down the middle to create a three dimensional space in the bracket and two identical halves on the right and left sides, with a slot depth greater than the vertical length of the trimmer, so that the trimmer can be completely concealed in the bracket enclosure to prevent possible infliction of cuts or more serious body injuries even if the operator's hand is in contact with the cutting edge of the trimmer blade accidentally.

Abstract: A combined deflection electrode and phase sensor electrode for a deflection type ink jet printer is made up of a ceramic support plate 19, a conductive layer 21 acting as the deflection electrode, layers of insulator 25 covering the conductive layer 21, and a patch of conductive material on the layers of insulator 25 to provide a phase sensor electrode 29 (Alternative constructions are also disclosed). A time of flight sensor electrode 31 may also be provided in the same way. The layers of insulator 25 prevent the sensor electrodes 29, 31 from being electrically connected, by splashes of conductive ink, to the deflection electrode provided by the conductive layer 21. The sensor electrodes 29,31 can have a larger sensing area than separately provided electrodes, allowing them to be further from the ink jet and thereby easing alignment requirements.

Abstract: A system and method is disclosed for dynamically generating a display document to conform to a display device according to viewing preferences of a user of the display device. The method selects display elements from an application description file, and maps them on a display area in a functional manner. For each user, a predetermined user profile can indicate recommended viewing preferences so that a desired presentation of the information can be produced accordingly.

Abstract: A method is provided for adjusting the operating amplitude of a modulation signal which influences the separation of drops from an ink jet of an ink jet printer. The method includes (1) determining the phase relationship between the modulation signal and the instants when successive drops separate from the ink jet for a plurality of amplitudes of said modulation signal (2) identifying the amplitude of the modulation signal at a predetermined characteristic point in the function of the phase relationship with the amplitude from the magnitude of the change of the phase relationship with the change of the amplitude; and (3) selecting the operating amplitude for the modulation signal in accordance with the amplitude identified in step (2).

Abstract: An ink jet printer automatically adjusts the amplitude of the modulation signal applied to a transducer (159) to break the ink jet into droplets. Correct modulation amplitude is determined from changes in jet break-up length, as determined by changes in jet break-up length, as determined by changes in jet break-up phase relative to the modulation signal.The printer has interchangeable print heads (3), which may have different nozzle sizes. A calibration code, specifying the particular values of ink pressure, jet velocity and charge correction required for optimum performance of a particular print head (3), may be entered into control logic (93), which operates the printer accordingly.Most print head components are mounted on a mounting subtract (111), with all connections being made to the underside of the mounting subtract (111) and sealed with a potting compound, to avoid damage.Ink viscosity is controlled in response to ink pressure, which is in turn controlled in response to ink jet velocity.

Abstract: In a continuous ink jet printer of the type in which drops can be deflected to a plurality of print positions, the path of undeflected drops is angled relative to the substrate 23 which is printed onto, so as to shorten the path of the most deflected drops. Since the most deflected drops are the least stable, this tends to increase print quality or allow greater printing speed. The plane of deflection of ink drops may be parallel to a circuit board 1 on which components of the print head are mounted, enabling a deflection electrode 15 and other electrodes to be formed directly on the circuit board, thereby reducing the number of components which have to be mounted separately onto the circuit board 1.

Abstract: A deflection arrangement for deflecting charged particles, e.g. ink drops in an ink jet printer, is arranged so that the potential dropped across an air gap between deflection electrodes varies with position along the air gap. This may be achieved by providing a varying thickness of dielectric material 31 on one deflection electrode 29, extending towards the other deflection electrode 27. Preferably, the width of the air gap varies to follow the fanning out of the paths of differently deflected particles (e.g. ink drops), and the variation in the potential across the air gap allows advantage to be taken of the fact that the dielectric strength (breakdown field strength) of air varies with the width of the air gap.

Abstract: To flush ink out of the ink gun 15 of an ink jet printer, it is connected to a suction source 23 (normally used for gutter suction) through a purge line 33, purge valve 35 and gutter valve 27, while the ink feed line 13 is connected to the solvent reservoir 17 through a feed valve 11 and a flush valve 37. This draws solvent from the solvent reservoir 29 into the feed line 13 and the ink gun 15. Then, the purge line 33 is isolated from the suction device 23, and the feed valve 11 connects the feed line 13 to a supply of ink pressurized by ink pump 5. The pressurized ink is driven into the feed line 13, driving some of the solvent already in the feed line and the ink gun 15 out through the nozzle of the ink gun 15. The ink flow is then stopped before fresh ink reaches the ink gun 15. This avoids ink drying in the ink gun 15, blocking the nozzle, while the jet is not running.
