  • Patent number: 6600612
    Abstract: An optical lens cell, especially useful in projection televisions, includes a tubular optic support structure having an interior with a longitudinal central axis and a first optic support surface extending around the longitudinal central axis. The first optic support surface receives a first optic having an outer circumferential edge and a first mounting surface portion adjacent the circumferential edge. The mounting surface portion of the first optic extends transverse to the longitudinal central axis. A plurality of raised surface members are provided on the optic support surface. At least one resilient member extends transverse to the longitudinal central axis and is configured to contact the mounting surface portion of the first optic when the first optic is positioned adjacent the optic support surface.

  • Patent number: 6441976
    Abstract: A projection television lens cell and system including a tubular optic support structure having an interior with a longitudinal central axis. A first annular support surface extends around the longitudinal central axis for receiving a first optic having an outer circumferential edge. The first annular support surface includes at least a first resilient member configured to contact the outer circumferential edge of the first optic and to be moved in a radially outward direction by the first optic relative to the longitudinal central axis. The resilient member assists in preventing substantial movement of remaining portions of the tubular optic support structure, for example, during assembly and any heat induced thermal expansion of the optic in use.

  • Patent number: 6104554
    Abstract: A projection television lens system having a device that distorts for telescopically adjusting an A/B assembly, the tubular member that carries the A and B lens elements within a focus mount of a projection television lens system. Additionally, at one end of the lens, there is provided a fixed mounting site, i.e. a mounting site which is fixed in position with respect to the CRT 9 assembly. A device is then provided which connects the fixed mounting site to the tubular member. The thermal and structural characteristics of the device are selected so that the device itself distorts in response to temperature changes and thereby moves the A and B lens elements toward or away from the C element in response to, respectively, increased or decreased ambient temperature. In the most preferred embodiment, the fixed mounting site is on the focus mount at the image side of the lens assembly.

  • Patent number: 5634584
    Abstract: Various mechanisms are provided for use in a surgical instrument. A shaft and an engaged lost motion operating knob are provided for rotation relative to a handle portion. A latch system prevents rotation of the shaft unless the shaft is rotated by the knob. A cartridge is provided for rotation at the distal end of the shaft. Engaging structures are provided for preventing rotation of the cartridge relative to the shaft when axial forces are applied to the cartridge. A loading tool is provided for engaging the cartridge to install the cartridge on the instrument. The cartridge includes a washer for engaging a carrier on which the cartridge is mounted so as to prevent rotation of the washer. The washer is adapted to engage a fastener advancing member in a first angular orientation and is disengaged when the cartridge is rotated to establish a second relative angular orientation.

  • Patent number: 5626587
    Abstract: Various mechanisms, and a method of operating them, are provided for use in a surgical instrument. A shaft and an engaged lost motion operating knob are provided for rotation relative to a handle portion. A latch system prevents rotation of the shaft unless the shaft is rotated by means of the knob. A cartridge is provided for rotation at the distal end of the shaft. Engaging structures are provided for preventing rotation of the cartridge relative to the shaft when axial forces are applied to the cartridge. A loading tool is provided for engaging the cartridge to install the cartridge on the instrument. The cartridge includes a washer for engaging a carrier on which the cartridge is mounted so as to prevent rotation of the washer. The washer is adapted to engage a fastener advancing member in a first angular orientation and is disengaged when the cartridge is rotated to establish a second relative angular orientation.

  • Patent number: 5470010
    Abstract: A unique hernia repair stapler is described which allows the forming of staples to attach prosthetics to tissue, or to approximate herniated tissue. The staple is useful in endoscopic operations and may be rotatable or stationary. The stapler has a unique forming and ejecting mechanism; as well, there is the availability of a loading mechanism useful for both cartridges and magazines of staples. An improved staple shape allows for better staple alignment, especially in a multiple load device.
