  • Patent number: 4642785
    Abstract: An electronic thermometer having a temperature sensing element for sensing a temperature and providing, over time, a series of temperature related electric parameters, and a data storing circuit connected to the temperature sensing element for storing the series of temperature related electric parameters. A data transmitting device is included which has an output and which is connected to the data storing circuit for transmitting the mentioned series of temperature related electric parameters upon command. A connector connected to the output of the data transmitting device has a command input which, when connected to a power source, receives an electrical command for commanding the data transmitting device to transmit data, and further has a data output device for providing thereon the data transmitted from the data transmitting device.

  • Patent number: 4463362
    Abstract: A movable ink reservoir carries a plurality of ink jet print heads and supplies ink to the heads by means of separate conduits. The reservoir includes baffle means therein formed to provide individual ink tanks for the print heads and to prevent or substantially minimize the sloshing motion of the ink as the reservoir is accelerated and decelerated in printing operation.

  • Patent number: 4462037
    Abstract: The level of ink in a reciprocating reservoir is automatically controlled for both printing and non-printing conditions. The reciprocating motion creates forces to cause the ink to move back and forth between the reciprocating reservoir and a main reservoir and a pump maintains the ink at one level during printing. The pump controls the direction and flow of ink moving between the reservoirs by continuous operation during printing and the ink is allowed to rise in the first-mentioned reservoir during non-printing.

  • Patent number: 4460905
    Abstract: The valve mechanism controls the flow of ink from a pressurized ink supply to a plurality of ink nozzles for printing bar codes. The mechanism includes a valve ball and a valve seat and an elastic diaphragm is positioned opposite the valve seat and is movable by action of a spring-loaded magnet armature to move the valve ball against the valve seat.

  • Patent number: 4433341
    Abstract: The level of ink in a reciprocating reservoir is automatically controlled for both printing and non-printing conditions. The reciprocating motion creates forces to cause the ink to move back and forth between the reciprocating reservoir and a main stationary reservoir and to maintain the ink at one level during printing. A check valve controls direction and flow of ink moving between the reservoirs and allows the ink to rise in the first-mentioned reservoir during non-printing.

  • Patent number: 4418353
    Abstract: A short tapered elastomer tube carries ink from a reservoir to an ink jet print head. The tube has a substantially constant inside diameter throughout the length thereof and a decreasing outside diameter along a portion of the length to provide a thin wall section for absorbing return pressure waves generated from the nozzle of the print head.

  • Patent number: 4412233
    Abstract: An ink-carrying conduit connected between an ink reservoir and a print head is placed within an enclosure for a portion of its length and which enclosure is an extension of the reservoir in large tubular form to contain the conduit in an ink vapor atmosphere.

  • Patent number: 4287523
    Abstract: A rotary ink jet printer has an ink supply in a rotating reservoir wherein a major portion of the ink supply is isolated from the ink feed system during the printing operation. A cylindrical reservoir has a central cavity and a surrounding or outer cavity connected by an orifice opened and closed by means of a ball valve to control the flow of ink or ink supply from the central cavity to the outer cavity.

  • Patent number: 4263504
    Abstract: A machine-readable matrix-type code has either repeated or non-repeated dot patterns in one direction representing digital characters which are read by a sensor moved in a direction which is generally normal to the patterns. The patterns of the code may be formed in a manner wherein the sensor views a portion of repeated patterns, or the code may be of lesser magnitude wherein the entire non-repeated pattern area is covered by the field of view of the sensor.
