US Patent:

42403634, Dec 23, 1980

Filed:

Aug 3, 1979

Appl. No.:

6/063873

Inventors:

Stephen R. Troy - Severna Park MD

International Classification:

F23G 900

US Classification:

110241

Abstract:

An incinerator bag that is primarily utilized for the storing of and subsequent destruction of classified documents. The bag is made of a three-ply construction which includes an inner and outer ply or layer of inflammable material such as paper and a middle ply of nonflammable open mesh material bonded therebetween. The nonflammable material may be in the form of, for example, glass fiber, metal wire or a non-metallic nonburnable material such as NOMEX. In addition, a closure element having a handle incorporated therewith is removably attached to the bag for utilization in sealing the bag when the bag is to be transported.

International Classification:

H04B 700

US Classification:

325 25

Abstract:

A channel traffic monitoring radio transceiver having basic transceiver components in combination with a microcontroller which provides the electronic operations which enables the transceiver to automatically establish the least congested channel of communication of a plurality of channels. The microcontroller incorporates therein a digital multiplexer, channel counter, channel traffic memory, channel address display, program read only memory, mode select switch, clock and microprocessor. After operation for a short period of time under the appropriate program stored in the program memory, the channel address corresponding to the lowest traffic number will be shown on the channel address display. This channel will be the least congested channel for communication between parties making initial contact on a congested channel.

Abstract:

A remote parameter monitoring system utilizes a series of half-wave rectifier diodes in combination with a unique overlapping wiring arrangement to provide for location-specific detection of a parameter condition existing at a plurality of spaced locations. In one embodiment of the invention, the system is used for monitoring cracks in helicopter rotor blades and indicating to the crew in the cockpit both the fact of a cracked blade and the specific blade which is cracked. In such embodiment, the system includes a three-phase alternating current transformer whose primary windings are supplied by the helicopter's three-phase alternating current generators and whose secondary windings make up part of the wiring loops between the cockpit and the rotor blades. By controlling currents flowing in opposite directions in the wiring loops, the system allows for blade-specific crack detection of up to six rotor blades by means of only three wires between the rotor blade assembly and the cockpit area.
