Abstract: An umbilical cord cutting and clamping device simultaneously severs an umbilical cord to form a maternal cord end and fetal cord end and releasably clamps the maternal cord end. A separate fetal cord end clip mounted in the device simultaneously secures the fetal cord end. The fetal cord end clamp is ejected automatically from the device after the fetal cord end has been clipped. The device provides a more uniform application of clamping force to the umbilical cord than scissors-like devices thereby reducing undesirable hemorrhaging from the clamped cord ends. The device can be used to clamp securely umbilical cords having a large variation in diameter.

Abstract: A captive fastener for securing two closure members together comprises a crew component adapted to be affixed to one of the closure members and a complimentary nut component adapted to be affixed to the other closure member. The screw component comprises a housing, a drive sleeve disposed within the housing for rotational movement therein, and a screw member in operatinal engagement with the drive sleeve whereby the screw member is axially movable between extended and retracted positions relative to the housing in response to the rotational movement of the drive sleeve. The nut component comprises a shell, a nut member disposed within the shell for limited axial and radial movement therein and fixed against rotation, and biasing means for urging against the axial movement of the nut member. The radial and axial movement of the nut member facilitates the alignment and engagement of the screw member with the nut member to eliminate binding when the closure members are assembled.

Abstract: A device for regulating delivery of power from an AC voltage source to a load such as a lamp, a motor, a heating element or the like is described. Electronic circuitry responsive to the AC voltage generates a periodic signal whose magnitude indicates the instantaneous phase angle of the AC voltage relative to the most recent zero crossover of the AC voltage throughout the entirety of each half cycle of operation. A comparator generates a triggering signal when the phase angle signal corresponds to a threshold signal which may be manually set by adjustment of a voltage divider or which may be generated by a sensor in response to a predetermined condition, such as ambient light level or temperature, which is to be regulated by appropriate delivery of power to the load. The triggering signal is applied to a triac series connected with the load to initiate conduction of load current.

Abstract: In wrapping machinery for wrapping articles in heat sealable plastic film, a web of film is drawn from a supply roll and is severed by pulling the film under tension downwardly onto the narrow edge of a thermal cut-off device, which may be a heated rod or blade, to melt the film material along a thin transverse line and to permit severance thereof by pulling. Following severance of the film, the film-wrapped package is sealed by placing the package on a pedestal hot plate. The temperature of the hot plate is higher than that of the thermal cut-off device used to sever the film. The hot plate is supplied by electrical energy from a single source through a temperature sensor and control. The thermal cut-off device obtains its heat by conduction from the hot plate.
