  • Patent number: RE32558
    Abstract: An electrically driven automatic film advance camera with automatic transition to rewind without external actuation is described. Film advance after each exposure occurs automatically after release of the shutter actuating button by means of an integral electric drive motor preferably contained within the film take-up spool. The end of film condition during film advance is signalled by a sudden onset in film tension, which actuates a switching system to reverse motor drive polarity and power the motor until the film is completely rewound into the cassette, whereupon motor actuation ceases. A take-up spool gear drive train remains fully engaged at all times. During the rewind operation both the take-up spool and the drive spool are driven simultaneously by the drive motor to facilitate film disengagement. A film engaging sprocket serves to govern film advance for framing purposes, the sprocket being principally in an idling state throughout the film advance operation.

  • Patent number: RE32560
    Abstract: A stabilized life raft utilizing a fluid filled depending buoy chamber for overall stabilization and including as improved features thereon a peripheral skirt chamber which fills with the raft supporting fluid upon deployment of the raft and serves as a temporary stabilizer while the buoy chamber becomes filled. The buoy chamber includes baffles to impede the flow of the stabilizing fluid from one portion of the chamber to another in the event of a sudden weight shift within the raft. An improved valve permits a more rapid inward flow of fluid upon deployment of the raft and yet prevents outward flow in instances where the buoyant raft is suddenly thrust upwardly by elements such as waves. The raft, because of the particular placement of the various structural elements in conjunction with the placement of the survival gear and inflation system, is automatically self-righting.

  • Patent number: 4712263
    Abstract: The neonatal blanket of this invention provides a generally elongated hemispheroidal, self-supporting thermal barrier for use with neonatal infants on open radiant warmer beds or convection-warmed infant incubators. The blanket can be formed from a single sheet of flexible clear plastic vinyl of similar material, shaped to provide a concave central cavity of a size to generally accomodate a neonatal infant, and having a relatively narrow, flat edge portion that extends around the blanket's perimeter. In use, the blanket is placed completely over the infant, so that its inner surface is close to but does not contact the infant's skin, and the flat edge portion both helps to support the blanket and provide an effective and efficient seal with the bedding material below. Thus, the blanket captures a volume of dead air space around the infant, which helps to reduce convective air currents within the infant's thermal microenvironment.
