  • Patent number: 4034841
    Abstract: A print wire solenoid device including a disc type plunger-restoring spring which consists of a continuous annular peripheral portion and spoke portions extending radially inwardly therefrom jointly to define a central opening for fitting engagement with the plunger. The plunger and the stationary core or stem members defining a solenoid gap, therebetween are both conically formed to minimize leakage of magnetic flux, thereby substantially increasing the effective flux density and hence the force of attraction. The disc spring, which is neither fixedly secured at any point to the plunger nor to the other adjacent components, is free from any stress concentration in operation and thus not only enables high speed printing operation with an increased length of stroke but facilitates fabrication of the device in combination with the conical formation of the plunger and stem members, which facilitates reduction in size and weight of the devices as well as in power consumption.

  • Patent number: 4034669
    Abstract: A setting mechanism for a postage meter for use in a continuous mail sorting and postage imprinting system which automatically weighs and meters each piece of mail. The system is designed to rapidly handle a large quantity of mixed mail. Mixed mail is continuously and synchronously fed in seriatim along a continuous feed path. Unsealed envelopes have their flaps wetted and sealed. All the envelopes are stopped at a weighing station where they are weighed, and the postage corresponding to their particular weight is computed. The determined postage value is used to continuously reset a postage meter which imprints the required postage upon each envelope as it arrives at a metering station. The actuator banks of the meter are controlled by stepper motors. The metering and weighing functions of the system are synchronized such that the postage meter will imprint the proper postage upon each piece of mail, despite the fact that several envelopes may be simultaneously in transit along the feed path.

  • Patent number: 4033443
    Abstract: Method and apparatus for producing a grey-tone image having areas of different average density values which are given by an n-digit binary number, all the bits of the binary number being interrogated in parallel by clock patterns. For the area to be printed an elemental area containing 2.sup.n pulses is selected which is printed in a total cycle of 2.sup.n .sup.- 1 clock pulses of the clock pattern. In this total cycle, at each clock pulse the drive of each pair of dots is determined in a manner such that the most-significant bit of the binary number is always used for driving while the remaining bits are used a number of times which depends upon their positional values. For this purpose, for each position of the binary number the clock pattern has a number of clock pulses which corresponds to the value of this position. The clock pulses for the individual positions are non-uniformly distributed in time, however, no clock pulses for the second and any further positions of the binary number coincide in time.

  • Patent number: 4029192
    Abstract: A digital electrical circuit for selectively activating a clutch mechanism for controlling the return speed of a business machine carriage. A carriage speed pulse transducer provides a series of sync pulses with intervals between each sync pulse being a function of the return speed of the carriage. These sync pulses and a carriage return command pulse are gated into control circuitry. The control circuitry provides a continuous pulse when the interval of the sync pulses signals that the carriage has exceeded a desired speed. The continuous pulse is used to activate the clutch mechanism for reducing the return speed of the carriage.

  • Patent number: 4027762
    Abstract: Each wire of a wire printer is driven by a separate pneumatic motor. Each motor is actuated by compressed air which is selectively passed through an electrically operated valve for each motor. Each valve is actuated by an electric signal indicating whether the associated printing wire should be driven to print a desired character. Coupled between a compressed air source and all of the individual valves is an electrically operated pressure control valve which is normally closed to block transmission of compressed air from the source to the individual valves. After the individual valves are opened by electric signals to permit the printing of a desired character, the control valve is then opened to permit transmission of the compressed air through the opened individual valves to actuate the individual pneumatic motors to drive the print wires necessary to print the desired character.

  • Patent number: 4026402
    Abstract: An incremental impact printer of the dot matrix type. Binary words representative of data to be printed along a line of print may be accepted from either the printer keyboard or the output of a computer or other source. The printer electronics provides for either a single character or a burst of characters to be substantially instantaneously printed upon receipt. The print head is always moved to the right of the last character printed to facilitate observation of that character. The next character is printed by first moving the print head to the left of the last character printed and then abruptly reversing the print head to print one or a burst of characters "on the fly". A novel registration system serves the dual function of accurately locating the proper position for a character to be printed and determining the direction of movement of the print head at any given instant.

  • Patent number: 4023665
    Abstract: A typewriter comprising a shiftable carrier supporting a rotatable type drum having a plurality of circumferentially extending rows of type characters thereon. Typing keys, when depressed, condition actuators and cause engagement of a power driven cyclic action clutch which drives a power bail to operate a conditioned actuator to rotate the type drum from any position it may be in to a new position to align a type character corresponding to the key depressed with the printing point. Certain of the keys, when depressed, position stops to limit axial movement of the type drum by the action clutch to align an appropriate one of the rows of type characters with the printing point. The action clutch also actuates a centralizer to accurately align the type drum prior to printing and, in addition, causes printing. A cyclic carrier shift clutch is engageable by the action clutch and by certain carrier shift control keys.
