摘要： A bending machine is provided to form a multiplicity of predetermined types of bends within several planes in elongated, heavy gauge workpieces of various sizes and shapes by pressure between a stack of dies and a pair of swingable anvil plates carried by elongated wings each of which is, in turn, swingable to adjust the distance between the anvils. Slide rails for the workpiece are readily accessible for loading and unloading. The die stack includes releasable vise-like clamps which grip the workpiece to preclude distortion during bending, and the stack can be raised or lowered to provide proper alignment of preselected die units of the stack.

摘要： An automatic closure assembly for a sliding panel, particularly of the screen door type, is disclosed. One or more power springs, operable in their linear ranges are mounted within a compact housing configured for ready attachment to a surface adjacent the sliding panel. The springs apply tension to a cord wound on a take-up reel within the housing. One end of the cord is screwed to the sliding panel such that as the panel is moved in an opening direction, the power spring(s) are wound in tension to apply closure forces to the panel. Different selections are provided for enabling an operator to select a plurality of different discrete tension forces to be applied by the closure assembly to the sliding panel.

摘要： Optical energy, provided from a remote user-operated source, is utilized to initially electrically charge a capacitor in a circuit that also contains an explosion initiating transducer in contact with a small explosive train contained in an attachable housing. Additional optical energy is subsequently supplied in a preferred embodiment to an optically responsive phototransistor acting in conjunction with a silicon controlled rectifer to release the stored electrical energy through the explosion initiating transducer to set off the explosive train. All energy transfers between the user and the explosive apparatus, either for charging it up or for setting it off, are conveyed optically and may be accomplished in a single optical fiber with coding to distinguish between specific optical energy transfers and between these and any extraneous signals.

摘要： A tungsten bridge device for the low energy ignition of explosive and energetic materials is disclosed. The device is fabricated on a silicon-on-sapphire substrate which has an insulating bridge element defined therein using standard integrated circuit fabrication techniques. Then, a thin layer of tungsten is selectively deposited on the silicon bridge layer using chemical vapor deposition techniques. Finally, conductive lands are deposited on each end of the tungsten bridge layer to form the device. It has been found that this device exhibits substantially shorter ignition times than standard metal bridges and foil igniting devices. In addition, substantially less energy is required to cause ignition of the tungsten bridge device of the present invention than is required for common metal bridges and foil devices used for the same purpose.

摘要： An improved planar heat pipe wick structure having projections formed by micromachining processes. The projections form arrays of interlocking, semi-closed structures with multiple flow paths on the substrate. The projections also include overhanging caps at their tops to increase the capillary pumping action of the wick structure. The capped projections can be formed in stacked layers. Another layer of smaller, more closely spaced projections without caps can also be formed on the substrate in between the capped projections. Inexpensive materials such as Kovar can be used as substrates, and the projections can be formed by electrodepositing nickel through photoresist masks.
