Abstract: ABSTRACT The invention is an interpreter intercommunication and public address system whereby even when a language other than specified languages for the appar-atus is additionally used, simultaneous interpretation of the language into the specified languages can be done without stopping the interpretation of the speci-fied languages.  The system comprises a first transmission circuit for transmit-ting an audio signal of a microphone for a speaker through a transmitter and a second transmission circuit for transmitting an audio signal at different trans-mitting frequencies through transmitters which are exclusively used for respective languages.  A language spoken by the speaker is interpreted into a medium langu-age at a first booth and a group of second booths is provided where the medium language is interpreted into the respective languages.  A first diode matrix consists of a plurality of transverse lines connected to a power source via a holding-releasing circuit and obverse lines which are connected respectively to interpretation instruction display lamps disposed in the first booth and the second booths.  Switch means are associated with each transverse line and the obverse lines are connected to a first selector arranged corresponding to the respective booths and may be connected to the transverse lines by diode means which are selectively placed in circuit between the obverse and transverse lines. A second diode matrix comprises transverse lines which are connected to the microphone for the speaker via a control switch means and a first amplifier and which are connected to earphones disposed within the first booth and the second booths and which are further connected to the power source via the holding-releasing circuit and an original removing circuit.  The second diode matrix also comprises obverse lines which are connected to the obverse lines of the first diode matrix and which may be connected to the transverse lines by diode means which are selectively placed in circuit between the obverse and transverse lines.  Microphones are connected respectively  to the first selector via second amplifiers and are disposed in the respective booths and a plurality of second selectors selectively switch between the second amplifiers and are connected respectively to the transverse lines of the first diode matrix and to respective microphones disposed within the booths, the first amplifier being connected to the microphone for the speaker so that the second transmission circuit may be connected thereto.  Thus, the system overcomes the shortcomings of conventional simultaneous interpretation apparatus which do not conveniently lend themselves to the use of a non-specified language.

Abstract: Abstract of the Disclosure A sensor chamber having one cavity containing coolant separated by a diaphragm from another cavity containing a fixed mass of inert gas is located within a safety assembly of a liquid metal-cooled nuclear reac-tor. The liquid cavity is in fluid communication with the coolant outside the chamber through a flow limiting orifice. An actuating bellows in fluid communication with the gas cavity is in contact with coolant outside the chamber and is connected to a push rod, which serves as a trigger for a poison bundle release mechanism. During slow changes in reactor coolant pressure experienced under normal operation, the diaphragm moves to equalize the gas cavity and liquid cavity pressures with the coolant pressure outside the chamber. The actuating bellows does not move because it is biased so that a threshold pressure difference is required before it will expand. Under a more rapid drop in coolant pressure, such as is associated with a loss of forced flow, the threshold is overcome and the actuating bellows will also move, thereby triggering the release mechan-ism to shut down the reactor. In an alternate embodiment, the actuating bellows is connected to the liquid cavity rather than to the gas cavity.

Abstract: Abstract of the Disclosure under Rule 72(b) A combination manifold absolute pressure and ambient absolute pressure sensor utilizing a single absolute pressure sensor and a second sensor which is devised to sense the difference between the manifold pressure and atmospheric pressure.  The second sensor is provided with a switch mechanism actuated by a diaphram at a preselected pressure difference between manifold pressure and atmospheric pressure. The actuation of the switch mechanism causes a sample-and hold circuit to sense the instantaneous manifold absolute pressure at the time of actuation of the switch and electrically add the sensed manifold pressure to the set difference between the manifold pressure and atmospheric pressure to provide a signal indicative of ambient absolute pressure. This signal is utilized to provide altitude compensation in a fuel injection system.

Abstract: ABSTRACT OF THE DISCLOSURE A linear variable phase transformer directly converts mechanical displace-ment information to phase information capable of varying fully over preferably more than a 120° period of a typical AC cycle and up to 360° or more phase variation. Three or more linearly arranged primary windings produce respective AC magnetic fluxes that are phase separated by equal amounts over such full period. A core, which is movably positioned relative to the primary windings, receives and/or combines one or more of such fluxes to produce an output flux that induces in a secondary winding an output AC electrical signal having a phase corresponding to that of the output flux and, thus, the positional relationship of the core and the primary windings. The output AC electrical signal is a time-based signal that can be utilized directly in analog applications or readily demodulated for digital use. The use of anti-fringing primary windings to reduce fringe effects and an elongated core that has an apparent or effective length shorter than its actual physical length also are disclosed.

Granted: 1982-07-27
Abstract: ABSTRACT OF THE DISCLOSURE          A method is disclosed for producing an electric thin layer circuit comprising at least one capacitor and a conductor path and/or a resistor.  The number of masks required for the production of such a thin layer circuit is reduced.  First and second layers of tantalum-aluminum alloy where the second layer has a tantalum share lower than the first, are applied on an insulating base.  In a first masking and etching technique, areas of the first and second layers are etched off outside the cir-cuit elements.  At least the second layer is anodically oxidized and the anodically oxidized surface is covered with a silicon dioxide layer so as to form a two layer dielectric for the capa-citor.  In a second masking and etching technique, not-required areas of the silicon dioxide layer external to the capacitor are removed.  By utilizing the silicon dioxide layer remaining as an etching mask, the not-required areas of the tantalum-aluminum oxide layer and the second tantalum-aluminum layer external to the capacitor are removed.  In a third etching and masking technique, a conductive surface layer is applied over the sili-con dioxide layer at the capacitor element to form a two-layer dielectric capacitor and over the first tantalum-aluminum layer to form the conductor path.
