  • Patent number: 6386693
    Abstract: The present invention pertains to an ink supply tank for an inkjet print head that can be installed in fixed fashion in an inkjet printer, having an ink reservoir that can be connected to an ink supply line leading to an inkjet print head, and having an ink delivery device that has actuating elements accessible from the outside, which can be brought into active engagement with corresponding, motor-powered drive elements of the inkjet printer, in which the ink delivery device feeds ink into the ink supply line at overpressure upon actuation of the actuating elements. In order to reduce the manufacturing effort and ensure a high level of functional reliability with an ink supply tank of such a type, the invention suggests that the ink delivery device have a pressure-generating device that acts on the ink reservoir and is coupled with the actuating elements, and that provides the ink reservoir with overpressure when the actuating elements are driven.

  • Patent number: 6354699
    Abstract: The present invention pertains to a procedure for manufacturing an ink-filled ink cartridge for an inkjet printer, which, for the withdrawal of ink, has connected to the ink space a tubular dome, the outer end of which is closed off by a pierceable, airtight, elastic membrane, and the inner end of which is covered with a fine-mesh filter screen, with the procedural steps: (1) evacuation of the ink space to a filling vacuum, (2) filling of ink into the ink space, (3) ventilating of the ink space, (4) evacuation of the ink space to transport vacuum, sealing of the ink space. In order to reduce as much as possible the air amount trapped in the dome during filling, the invention suggests that before the evacuation to transport vacuum, a stiff covering be applied from the outside in front of the membrane in a sealing manner, thus trapping a defined air volume.

  • Patent number: 5634548
    Abstract: A brick dehacking apparatus. The dehacking apparatus is operable to blend the upper and lower courses of brick from a kiln car with each other and further blend these brick with brick from the middle courses of the stack in preparation for stacking and strapping.

  • Patent number: 5626139
    Abstract: An improved tympanic thermometer incorporates twin thermopiles, each including a set of sensing junctions and a set of reference junctions configured so that three of the four sets of junctions sense only the temperature of an ambient environment, while the fourth set of junctions receives energy from both the ambient environment and from the tympanic membrane of a patient whose temperature is being taken. The energy received from the tympanic membrane is intentionally not bandwidth limited, enabling an accurate temperature measurement to be calculated which is substantially independent of wavelength. A light pipe is optionally included to assist in carrying radiation from the tympanic membrane to the fourth set of thermocouple junctions used for temperature sensing. In the preferred embodiment a dielectric coating is internally applied within the light pipe, and interchangeable tubes may be provided which conform to the aural physiology of different patients, including children.

  • Patent number: 5443357
    Abstract: An apparatus for forming a tyne layer in an automatic brick stacking system having a conveyor for moving courses of brick from a kiln car to a stacking and straping station is disclosed. The apparatus includes a set-down transfer head for removing a course of brick from the conveyor. A separation conveyor receives brick from the set-down transfer head. The separation conveyor has a plurality of parallel, spaced-apart conveying means for moving the bricks in a longitudinal direction. A stop means engages and stops the movement of bricks therepast. A lift means is disposed between the conveying means and between one end of the separation conveyor and the stop means for lifting and redepositing a portion of the bricks upstream of the stop means. The conveying means, stop means, and first lift means are sequentially operated in a cooperative relationship to space the rows of brick apart in the longitudinal direction of conveyance and at predetermined intervals to form the tyne layer.

  • Patent number: 5437535
    Abstract: A brick dehacking apparatus is disclosed. The dehacker is operable to vary the number of rows of brick and number of brick in a row of brick courses removed from a kiln car and selectively combine and alternate courses of brick removed from at least two kiln cars in preparation for stacking and straping.

  • Patent number: 4542539
    Abstract: This biologically compatible surgical prosthetic implant has a multi-layer coating formed from metallic particles having sizes which increase in the direction from the metallic body of the implant toward the surface of the coating which is to interface with bone. The gradation is achieved by first depositing a layer of small particles, for example microspheres, of metallic coating material on the surface of the implant, then depositing progressively larger particles in subsequent layers. The particles may be deposited by any one of a number of well-known processes including but not limited to a flame-plasma process, in which several parameters are controlled as functions of the size of the particles.The resultant coating has minimum density and maximum porosity at its outer surface to encourage ingrowth of bone.
