Abstract: ABSTRACT OF THE DISCLOSURE:             An improved line card circuit usable with key telephone system is adapted to permit a message to be automatically trans-mitted from a subscriber key telephone station when operated to place a telephone line in a hold condition.  A coupling circuit interfacing the message source and the telephone line during the hold condition of the line provides a high degree of cross-talk isolation.  The coupling circuit also has the feature of auto-matically limiting to a predetermined level the power of the output signal supplied to the telephone line.  A [stoppable] option is provided by the coupling circuit to permit its operation with a standard eight ohm high fidelity amplifier source as well as with at 70 volt intercom systems.  The line card circuit, besides these features, includes circuitry to allow full supervisory control of a telephone line to be exercised by a user of the subscriber key telephone when such unit is not in the hold condition.  The line card circuit also includes circuitry that controls the operation of audible and visual indicators of an associated key telephone.

Abstract: ABSTRACT       The improved system for liquid cooling of a rotor of a rotary piston mechanism applies to those types having two housing walls spaced apart by a trochoidal shaped peripheral wall to define a multi-lobed cavity within which a multi-cornered rotor is eccentrically supported for planetary movement, and in which the rotor has a hub portion and peripheral wall portions defining therebetween cooling spaces which communicate with the area exteriorly of the rotor through an opening adjacent each end of the hub portion.  The improved rotor cooling system comprises a cooling liquid discharge nozzle disposed in at least one of the housing walls and connecting the discharge nozzle to a source of pressurized cooling liquid.  The discharge nozzle is positioned so as to direct emitted cooling liquid into the adjacent rotor opening and the cooling spaces in the rotor.       In a narrower aspect of the invention a regulator and valve assembly is provided to control flow of cooling liquid to the discharge nozzle in accordance with the pressure conditions of the cooling liquid and temperature and load operating conditions of the engine.

Abstract: ABSTRACT    A bearing and drive mechanism to rotate precisely spacecraft components, in particular, an array of solar panels.  A drive shaft in such a mechanism designed for long-life capability is required to have high stiffness in addition to axial and radial constraints for precise rotation relative to a fixed housing.  A preloaded pair of duplex, coacting angular contact ball bearings mounted between the shaft and housing provides axial and radial shaft constraint.  A single bearing, mounted on an axially compliant diaphragm, is preloaded by resiliently flexing the diaphragm.  The preloaded single bearing provides a radial constraint and thus shaft support at the mounting of the single bearing, this additional support increasing the stiffness of the shaft against moments and forces imposed on the shaft.  The compliant diaphragm permits axial thermal deflections of the shaft relative to the housing, such deflections  caused, under temperature changes, by the difference in thermal expansion properties of the shaft and housing.

Abstract: ABSTRACT OF THE DISCLOSURE        A method and apparatus, for supporting spurious interference components that arise in video recording apparatus, of the type which utilize frequency modulation of a carrier signal with a video signal, is disclosed.  The invention suppresses an unwanted spurious interference signal component substantially to zero by generating the second harmonic of the video information modulating signal and adding the second harmonic to the modulating signal at a predetermined phase and amplitude prior to being modulated upon the carrier signal.  The phase is such that the result-ing signal is that which, when the second harmonic is added, heightens the upward deviating peaks and flattens the lower peaks of the fundamental modulating signal.  The amplitude of the second harmonic signal is added in direct proportion to the square of the modulating index of the modulating signal.

Abstract: PROCESS FOR THE CONCENTRATION OF DILUTE SULFURIC ACID SOLUTIONS          Abstract of the Disclosure The invention relates to a process for the concen-tration of metal salt-containing dilute sulfuric acid solutions.  The solution is first preconcentrated by indirect heating and evaporation to a concentration at which no substantial amounts of the salts are precipitated under the reaction conditions, then the preconcentrate is reconcentrated by mixing it with a sufficient amount of hot, highly con-centrated sulfuric acid to produce evaporation of water from the solution, and the salts which precipitate are then removed.  In this way a concentrated, and to some extent purified, sulfuric acid solution is obtained without the usual difficulties of metal salt crustation on the indirect heating means or harmful decomposition products in the waste gas.

Abstract: ABSTRACT OF THE DISCLOSURE        An electronic time-of-day met?ring system is disclosed for measuring electrical power by at least two different mechanical recording devices depending on the time-of-day and time of week in which the electrical power is being consumed.  A conventional kilowatt hour meter includes a set of decade gear driven dials which register the kilowatt hours consumed on a continuous basis.  At least one other set of decade gear driven dials is provided for registering the consumption of kilowatt hours during preselected peak power usage inter-vals.  A single MOS integrated circuit controls the operation of the alternate circuit controls the dials. This circuit utilizes as its time base the 60 Hz line voltage derived from the energy distribution system being metered.  A clock circuit generates timing signals for a clock control circuit which includes a circulatory memory which is preprogrammed to contain the times at which one or more alternate sets of dials are to be actuated.  When the clock time equals a stored time a gating signal is generated.  At the same time a function command signal, also stored in the circulatory memory, is passed through the enabled gate for engaging or disengaging the alternate set of decade gear drive dials, depending on the value of the function stored.  The gated signal controls the energization of a bistable clutch which engages the alternate set of dials.  A method for register-ing total energy consumed by a metered system as well as energy consumed during preselected time intervals is also disclosed.
