Abstract: POWER MODULE ASSEMBLY            ABSTRACT OF THE DISCLOSURE          A power module assembly in the form of an electrochemical battery which is composed of a plurality of anode-cathode units arranged in stacked relation within a housing.  It is necessary that the anodes and cathodes be tightly pressed together at all times so that as an electrolyte flows therebetween there will be the desired electrochemical reaction.  This is accomplished by a pres-sure device.  Since the anodes are consumable, as the anodes are consumed it is necessary that the stack be compressed to that the same pressure may be maintained between the anodes and cathodes.  Accordingly, the pres-sure device is capable of expanding and at the same time transmitting constant pressure on the stack.

Abstract: ABSTRACT OF THE DISCLOSURE      A cache system includes a storage unit organized into a plurality of levels, each including a number of multiword blocks and a corresponding number of address selection switches and address registers.  Each address selection switch has a plurality of different positions connected to receive address signals from a plurality of address sources.  A decoder circuit generates output signals for controlling the operation of the address selection switches.          In response to previously defined level signals, the decoder circuit conditions a specified one of the number of switches to switch from a first position to a second position.  An address specifying the location into which memory data is to be written is clocked into one address register while the address specifying the location from which an instruction is to be fetched is clocked into the remaining address registers.  A comparator circuit compares signals indicating the level into which memory data is to be written with signals indicating the level from which a next instruction is to be fetched. The comparator circuit generates signals which cause the delay of instruction access when there is a conflict between writing memory data and accessing instructions.

Abstract: Abstract of the Disclosure A closed two phase liquid-vapor heat transfer device is provided which is independent of orientation and requires no wick.  A micro bellows containment vessel is filled with liquid to form a coolant vapor phase bubble which is centered within the vessel due to the surface energy characteristics of the fluid.  Heat input at the evaporator section results in evaporation of the liquid at the liquid-vapor interface.  The vapor flows across the bubble and condenses on the opposite side where heat is rejected and liquid is replenished to the evaporator section by flow through the continuous liquid film.

Abstract: Abstract A circuit for regenerating the carrier from a PSK signal is dis-closed.  The circuit has a first and a second output point, having different equivalent noise bandwidths determined, respectively by using broad equiva-lent noise bandwidth filter and a narrow equivalent noise bandwidth.  The phase difference between the output points is detected by a phase detector, and the phase of the signal at the first output point is changed by a phase shifter on the basis of the result of such phase difference detected.  In this way the signal obtained at the first output point which has a good transient response is used as the output signal and when this signal exhibits phase-skipping the phase skipping is removed.  In addition, either channel switching or polarity inversion of the demodulated baseband signal may be performed on the basis of the result of such phase difference.

Abstract: ABSTRACT           Disclosed is a microwave frequency generator for producing a microwave signal with high frequency accuracy, high spectral purity, low noise and high frequency stability.          It is known to phase lock the fundamental microwave oscillator to a highly stable crystal oscillator at lower frequency and convert to a higher output frequency with a multiplier or harmonic generator but fm noise is also multiplied.  The present invention avoids this problem by using MESFET frequency dividers to phase lock a microwave oscillator to a stable reference oscillator without the need for frequency multipliers.          The MESFET frequency divider provides signal gain instead of loss during operation.

Abstract: ABSTRACT     The concentration of deuterium relative to hydrogen in a hydrofluorocarbon is increased by con-tacting the hydrofluorocarbon, in the presence of an alkali metal amide, with an amine having a concentration of deuterium that is greater than that which provides equilibrium with the hydrofluorocarbon.  In a preferred embodiment, a compound enriched in deuterium is pro-duced by first exposing trifluoromethane to infrared laser radiation to selectively cause a chemical reac-tion involving deuterium-containing molecules.  The deuterium-depleted trifluoromethane is deuterium re-plenished by exchange with an amine, and the compound enriched in deuterium is converted to heavy water. Heavy water is useful in certain types of nuclear reactors.
