Abstract: A vacuum pack encapsulation device for containment of metal members to be joined together by solid-state welding. Positioners are assembled inside the pack in and around the metal members for support thereof during the welding process. Certain of the individual elements of the pack are spaced from one another and spaced from the metal members by deformable spacers. The spacers deform under compression force to permit the pack elements to move toward one another whereby the compression force is transmitted to the metal members to effect welding thereof.

Abstract: A SELF-EXCITED PNEUMATIC OSCILLATOR IS DESCRIBED WHICH INCLUDES A RECIPROCATING VALVE MEMBER THAT IS CAPABLE OF HIGH FREQUENCY OPERATION. THE VALVE MEMBER IS DISPOSED IN A HOUSING HAVING A FIRST ACTIVE SPRING CHAMBER, AND A SECOND SPRING CHAMBER SPACED THEREFROM. BOTH SPRING CHAMBERS ARE CHARGED BY A SOURCE OF PRESSURIZED AIR AND ACT UPON OPPOSITE ENDS OF THE VALVE MEMBER. A DISCHARGE CHAMBER IS DISPOSED SO THAT IT IS BROUGHT PERIODICALLY IN COMMUNICATION WITH THE FIRST CHAMBER AS THE VALVE RECIPROCATES, WHEREBY THE OSCILLATOR CONVERTS THE ENERGY OF THE PRESSURIZED FLUID FLOWING FROM THE ACTIVE CHAMBER TO THE DISCHARGE CHAMBER INTO SELF-SUSTAINED RECIPROCATING MOTION OF THE VALVE. THE OSCILLATOR INCLUDES A FILTER BETWEEN THE SOURCE OF PRESSURIZED AIR AND THE SPRING CHAMBERS TO MINIMIZE ALTERNATING PRESSURE FLUCTUATIONS IN THE AIR SUPPLY LINE, THEREBY ENHANCING EFFICIENCY. THE FILTER AND VALVING PROVIDE FOR AUTOMATIC SELF-STARTING FOLLOWED BY A SHIFT TO A PREDETERMINED VALVE POSITION FOR EFFICIENT OPERATION AT MAXIMUM LOAD.

Abstract: An interlaced electronic commutator system having use in a time division multiplex system. A timing circuit and a plurality of subcommutator circuits are employed, each one of which periodically gates input data for a relatively long period of time, isolates the gated input data, then gates only the last portion of the isolated input data as the subcommutator output. The outputs of all the subcommutators are then combined in a high rate pulse amplitude modulated waveform.

Abstract: A MULTICHANNEL RECORDING SYSTEM IS DESCRIBED FOR RECORDING BOTH DIGITAL AND ANALOG INFORMATION. THE RECORDING SYSTEM INCLUDES APPARATUS FOR CONVERTING ANALOG INFORMATION INTO DIGITAL INFORMATION HAVING A PREDETERMINED FORMAT. EACH TRACK OF THE RECORDING APPARATUS RECEIVES A SERIES OF ENCODED FORMAT WORDS CONTAINING A PLURALITY OF TERNARY NRZ PULSES, EACH REPRESENTED BY ANY ONE OF THREE VOLTAGE LEVELS, POSITIVE, NEGATIVE OR ZERO VOLTS DURING A BIT INTERVAL, SUCH THAT THE AVERAGE LEVEL OF EACH WORD IS 0 VOLTS. THE SPECTRUM OF A SIGNAL COMPOSED OF A SERIAL SEQUENCE OF THESE FORMAT WORDS IS CAPABLE OF BEING RECORDED ON A MAGNETIC TAPE RECORDING TRACK WITH A MUCH HIGHER PULSE PACKING DENSITY THAN HERETOFORE POSSIBLE WITH CONVENTIONAL NRZ OR OTHER BINARY RECORDING TECHNIQUES. THE PLAYBACK APPARATUS WHICH FORMS PART OF THE RECORDING SYSTEM INCLUDES CIRCUITRY RESPONSIVE TO THE ZERO AVERAGE PROPERTY OF THE RECORDED WORDS, AND CONTROLS THE TIMING OF THE READOUT OF THE RECORDED INFORMATION SO AS TO PROVIDE PRECISE TIME COHERENCE BETWEEN ALL OF THE RECORDED CHANNELS. THE LATTER CIRCUITRY ALSO CONTROLS THE SYSTEM FOR DESKEWING THE SIGNALS RECORDED SIMULTANEOUSLY ON PARALLEL TRACKS ON THE TAPE DURING PLAYBACK, THEREBY FURTHER ENHANCING THE CAPABILITY OF THIS SYSTEM TO RECORD INFORMATION WITH EXTREMELY HIGH PULSE PACKING DENSITY. BOTH RECORDING AND PLAYBACK IS CONTROLLED BY A COMMON ACCURATE CLOCK SO AS TO FURTHER INSURE COHERENCE BETWEEN SIGNALS RECORDED ON ALL CHANNELS. ALSO INCLUDED IN THE RECORDING SYSTEM IS AN INPUT-OUTPUT SECTION WHICH TRANSLATES INPUT ANALOG INFORMATION INTO DIGITAL FORM FOR RECORDING IN THE VARIOUS CHANNEL AT RATES AND WITH THE FORMAT COMPATIBLE FOR RECORDING WITH THE SYSTEM. THE INPUT-OUTPUT SECTION ALSO REARRANGES THE DIGITAL INFORMATION READ FROM THE MAGNETIC RECORD INTO ITS ORIGINAL ANALOG OR DIGITAL FORM, AS THE CASE MAY BE.

Abstract: A HYDROACOUSTIC TRANSDUCER IS DESCRIBED HAVING A RADIATOR IN THE FORM OF A FLEXING DISC AND AN ACOUSTIC DRIVE MEMBER FOR COUPLING A FLUID-FILLED CAVITY, THE PRESSURIZED FLUID IN WHICH IS ACOUSTICALLY MODULATED, TO THE RADIATOR. THE DRIVE MECHANISM INCLUDES A PISTON WHICH IS GUIDED IN AN OPENING IN THE HOUSING WHICH EXTENDS INTO THE CAVITY CONTAINING THE PRESSURE-MODULATED FLUID. AN ANNULAR-SEAL IS PROVIDED IN THE OPENING AND EXTENDS PARTIALLY INTO THE PISTON AND INTO THE WALL OF THE OPENING. THE WALL OF THE OPENING AND THE PISTON IS CONSTRUCTED TO PROVIDE A CLAMPING STRUCTURE SO THAT FLUID IS PREVENTED FROM LEAVING THE CAVITY WHILE THE PISTON IS PERMITTED TO VIBRATE IN RESPONSE TO THE ACOSTIC ENERGY OF THE MODULATED FLUID.

Abstract: An FM signal discriminator circuit is described having a pair of emitter follower transistors of complementary symmetry cross coupled to each other. The output is taken at a base to emitter junction of one of the transistors so that voltage drops across the base to emitter junctions cancel, thereby enhancing linearity and temperature stability of the circuit. Discriminating action is obtained by transfer of charge between capacitors, one of which is contained in a charging circuit connected between the cross coupled transistors. The voltage across the last-mentioned capacitor is a function of the frequency of an input signal.

Abstract: BROADLY, THIS DISCLOSURE IS DIRECTED TO A SYSTEM FOR PRODUCING AURAL PSYCHOLOGICAL DISTRUBANCES AND PARTIAL DEAFNESS OF THE ENEMY DURING COMBAT SITUATIONS. ESSENTIALLY, A HIGH DIRECTIONAL BEAM IS RADIATED FROM A PLURALITY OF DISTINCT TRANSDUCERS AND IS MODULATED BY A NOISE, CODE OR SPEECH BEAT SIGNAL. THE INVENTION MAY UTILIZE VARIOUS FORMS AND MAY INCLUDE MOVABLE RADIATORS MOUNTED ON A VEHICLE ORIENTED TO CONVERGE AT A DESIRED POINT, INDEPENDENTLY POSITIONED VEHICLES WITH A COMMON FREQUENCY MODULATOR, OR MEANS EMPLOYED TO MODULATE THE ACOUSTICAL BEAM WITH RESPECT TO A FIXED FREQUENCY. DURING COMBAT, FRIENDLY FORCES WOULD BE EQUIPPED WITH A REFERENCE GENERATOR TO PROVIDE AURAL DEMODULATION OF THE PROJECTED SIGRAL, THEREBY YIELDING AN INTELLIGIBLE BEAT SIGNAL WHILE ENEMY PERSONNEL WOULD BE RENDERED PARTIALLY DEAF BY THE PROJECTED SIGNAL AS WELL AS BEING UNABLE TO PERCIEVE ANY INTELLIGENCE TRANSMITTED IN THE FORM OF A MODULATED BEAT SIGNAL.
