摘要： A missile severance device for severing a structural surface member of a body is constructed of a pair of plate members separated by a collapsible liner member ring. An explosive charge is contained with the volume defined by the pair of plate members and the liner member ring. One of the plate members includes a booster explosive charge that serves to detonate the explosive charge so as to collapse the liner member ring and create a directed jet toward the structural surface member intended to be cut.

摘要： A detection circuit for use in an electrical power converter having at least one negative output rail, for detecting the voltage of the negative output rail and for converting the voltage to a positive output voltage. The detection circuit includes an input port for receiving the negative output rail voltage from an electrical power converter, an output port, a ground reference potential, a node having a voltage that is positive with respect to the ground reference potential, and a circuit for generating a measurement current from the node to the ground reference potential. The value of this measurement current is a function of the negative output rail voltage received at the input port. A circuit is further provided for generating an output voltage at the output port that is positive with respect to said ground reference potential and whose value is a function of said measurement current. The detection circuit can be used with conventional pulse-width modulators of switch mode power supplies in order to regulate the value of the negative rail voltage.

摘要： An electronic camera is provided as a module that attaches to the signal bus of a PC-compatible computer. The camera includes a minimum of components, particularly an image sensor and an A/D converter, and a PC-compatible interface connector for mating with a bus extension connector on the computer. By directly presenting digitized data from the camera to the signal bus of the computer through the bus connector, the camera can be kept relatively simple and the computer can be relied upon to perform image processing, storage, and display.

摘要： A Circuit for reversing the direction of current flow in a rectifying device of a power converter during a time interval just prior to when the rectifying device is to be rendered non-conductive is described. The current reversal substantially reduces or eliminates reverse-recovery currents in the rectifying device, which may cause short circuits and needlessly dissipates power. The circuit comprises an energy source, a magnetic storage device, and a switch for coupling the magnetic storage device to the energy source. The magnetic storage device may comprise an inductor or a transformer. The energy source may include a voltage source, the converter's input voltage, the output voltage, or a winding magnetically coupled to another magnetic storage device of the converter. The reversal circuit includes a circuit for coupling the reversing current to the rectifying device such that it partially or completely reverses the flow of current in the rectifying device.

摘要： A method and apparatus for stacking zippered plastic bags maintains the top bag of the stack in a generally horizontal relationship by controlling the position of a stacking table which supports the stack. At least a portion of the stacking table which supports the stack is gradually pivoted in the area of the bag zippers as a stack forms. Preferably, the stacking table is controlled to also maintain the top of the stack at a generally constant level while the stack is forming.

摘要： A method and apparatus for continuous cleaning of bag making machinery is provided. A single roll with a cleaning material attached thereto contacts a rotating drum to remove debris from the surface thereof. When the portion of the cleaning material in contact with the drum becomes saturated with debris, the roll is rotated to present fresh cleaning material to the surface of the drum. The compact design of the cleaning apparatus permits its use in the limited space found around bag making machinery.

摘要： A method and apparatus for supplying gas to a vacuum drum device and which substantially reduces or eliminates the problem of particle and debris buildup in the vacuum passages of the device is provided. The apparatus supplies gas, preferably at a pressure greater than atmospheric pressure, to the vacuum ports of a vacuum drum and includes a source of vacuum, a source of gas, and a rotatable vacuum drum. The drum includes a plurality of vacuum ports on the surface thereof, with the vacuum ports communicating with a plurality of vacuum passages extending generally outwardly from the interior of the drum. A valve alternately connects the passages to the vacuum source and to the source of gas. The selective exposure of the vacuum ports to either a source of vacuum or a source of gas prevents smoke, particles, and other contaminants from being drawn into the vacuum passages of the drum during operation of the system.
