摘要: A high speed print pin driver for a dot matrix printer. A U-shaped core having a pair of parallel spaced legs is formed of a plurality of laminations of silicon iron. A rectangular magnetic field-forming coil is on one of the legs. A magnetic flux plate of silicon iron is disposed across the open end of the U of the core between the legs, the flux plate being attached to the other of the legs and in close-spaced adjacent relationship to the one of the legs. The top surface of the flux plate over the other leg is slightly longitudinally beveled and the flux plate has a bore therethrough over the one of the legs and longitudinally aligned therewith. A longitudinal spring-metal beam is disposed along the flux plate, being attached on one end to the beveled top surface and extending out over the flux plate on the other end. The beam includes an armature piece of magnetically attractable material disposed within the bore in the flux plate. The beam tapers from adjacent the armature piece to the other end thereof and has one edge forming a reinforcing rib along the tapered portion. A print pin is carried by the other end of the beam disposed substantially parallel to the one leg of the core.

摘要: A dot matrix print head includes a solenoid and a spring assembly for driving a print pin, with a positioning means for holding the assemblies in a predetermined relation. The solenoid assembly preferably has a first positioning means adjacent its upper surface and a second positioning means preferably forms a part of the spring assembly. The first and second positioning means are preferably circumferential and the second means is preferably adapted to engage the first positioning means around more than 180.degree. of arc thereof and is expandable to permit sliding engagement with the first positioning means so as to hold the spring assembly locked onto the solenoid assembly. Preferably a molded stiffening rib is carried by the spring assembly and extends from the armature to the pin-carrying tip of the spring assembly. The molded pin support is formed integrally with the stiffening rib and permits rotation of the end of the pin in the support. It is also preferred that there be a molded pad carried by the stiffening rib to engage an impact absorbing member during return of the printing pin from printing position.

摘要: A method and associated apparatus for quickly and accurately advancing paper between the platen and printing mechanism on a line-by-line basis in a high speed printer for printing lines of text including a platen and a printing mechanism disposed adjacent the platen. The method comprises the steps of, threading the paper from the supply input through a powered first drive mechanism disposed before the platen and printing mechanism, through a frictional gripping mechanism disposed adjacent the platen between the platen and the first drive mechanism and adapted for frictionally gripping the paper under a gripping force sufficient to prevent advancement beyond the frictional gripping mechanism by a pushing force on the paper while permitting the paper to be pulled through the frictional gripping mechanism by a second drive mechanism, between the platen and printing mechanism and into engagement with a powered second drive mechanism disposed after the platen and printing mechanism and adapted for gripping and rapidly moving the paper a feed distance; using the powered first drive mechanism to receive the paper and advance at least one dot line feed distance of paper to form a supply loop between the powered first drive mechanism and the frictional gripping mechanism; and, at the time for advancing the paper by the feed distance, which may be while the first drive mechanism is still operating, using the powered second drive mechanism to pull the paper through the frictional gripping mechanism the feed distance from the supply loop.

摘要: In a serial printer wherein a bi-directionally operating motor drives a carriage in an oscillatory motion between two end points, an improvement for minimizing the time for direction reversal of the carriage. There is a ballistic rebound device for transferring energy of the moving carriage in one direction into a resilient member and for retransmitting energy absorbed by the resilient member back into the carriage in a direction opposite the one direction. There is also an electrically operated brake for selectively coupling the ballistic rebound device to the carriage. Sensing apparatus is provided for sensing the position of the carriage with respect to the two ends. Finally, logic connected to the sensing device is provided for removing a drive voltage from the motor and connecting the ballistic rebound device to the carriage at points with respect to the end points which wil cause the carriage to stop motion in one direction at a desired position with respect to the end points and for applying a drive voltage to the motor and disconnecting the ballistic rebound device from the motor shaft at points with respect to the end points which will cause the carriage to stop and accelerate to a maximum velocity in a direction opposite the one direction in a minimum amount of time. One version employs a single brake carried by the carriage and another employs a pair of brakes disposed adjacent respective ends of carriage movement.

摘要: An improvement to a dot matrix printer of the shuttle variety wherein a printhead is oscillated from side to side within a printer base. The shuttle is disposed within a ballistic energy transfer device mounted for oscillating movement from side to side in the opposite direction to the instantaneous movement of the shuttle. A rebound spring is operably connected to exert a rebounding force against the shuttle to aid it in reversing direction. Also, a centering spring is operably connected for exerting a centering force against the ballistic energy transfer device. A linear motor is connected for driving the shuttle back and forth in an oscillating motion with respect to the ballistic energy transfer device. Optionally, the linear motor is connected for driving the ballistic energy transfer device back and forth in an oscillating motion with respect to the printer base. The turnaround time of the shuttle is adjusted by adjusting the span of the shuttle or the spring constant of the rebound spring. Linear encoders are provided to determine the shuttle position as the shuttle moves back and forth.

摘要: A method for generating visible light and a deceptive signature pattern for an emissions producing asset is disclosed. The method comprises illuminating at least one lighting assembly of the asset in a pattern. The pattern produces visible light synchronous with a signature of a wavelength in a substantially similar range as normal emissions of the asset. The method also comprises modulating a radiant intensity of the signature of the at least one lighting assembly between a minimum radiant intensity and a maximum radiant intensity in a repetitive cycle and operating a controller to regulate the pattern.
