Abstract: Abstract of the Disclosure A process is described for the preparation of mixed iso-meric methylene-bridged polycyclohexylpolyamines wherein a mixed isomeric methylene-bridged polyphenyl polyamine mixture having a functionality of from about 2.0 to about 3.3 is pretreated by con-tacting the mixture and hydrogen with a nickel-containing hydro-genation catalyst at a temperature of from about 25°C. to about 250°C. under a pressure of about 500 to about 15,000 psig.  The pre-treated isomeric polyamine is then hydrogenated in the presence of ammonia under conventional hydrogenation conditions employing a ru-thenium-containing hydrogenation catalyst.  The pretreatment step allows the utilization of mixed isomeric methylene-bridged poly-phenyl polyamine feed mixtures for the production of isomeric methy-lene-bridged polycyclohexylpolyamines in high yields without atten-dant deactivation of the ruthenium hydrogenation catalyst hereto-fore observed.  The process is particularly applicable to continu-ous operation.

Abstract: METHOD FOR MAKING METALLIC SANDWICH STRUCTURES                ABSTRACT A method for fabrication of metallic sandwich structures in which metal blanks, preferably of a titanium alloy, are joined at selected areas and expanded superplastically to form a desired sandwich structure.  Various techniques for joining, preferably diffusion bonding, selected areas of the metal blanks are disclosed. These include treating the metal blanks at selected areas to prevent bonding at those areas and selective application of pressure during bonding.  In the preferred enbodiment, the metal blanks are positioned in a stack after being treated at selected areas.  The stack is positioned relatives to shaping members and heated to a temperature suitable for superplastic forming and diffusion bonding.  Compressive pressure is applied for the selective diffusion bonding.  The stack is expanded into contact with the shaping members by increasing the internal pressure therein, preferably with inert gas, thus forming the desired shaped sandwich structure in one operation.

The secondary element of the system includes a rotatable follower magnet magnetically coupled to the bar magnet and a pointer mounted on the shaft of the follower magnet whereby the pointer sweeps from zero to maximum along a scale as the float travels from its low to its high position.  A mass is eccentrically mounted on the shaft of the follower magnet, the position of the mass relative to the shaft axis being adjusted to produce a moment compensating for the non-linear relationship between flow rate and pointer movement.

Abstract: Abstract of the disclosure A dynamic MOS one transistor cell memory having a plurality of divided bit lines and a corresponding plurality of flip-flop sense amplifiers.  Each bit line being divided into two electrically balanced parts which run adjacent and parallel to each other, and extend from the input/output nodes of their corresponding flip-flop sense amplifier to a balanced data access bus.  The balanced data access bus being connected, in turn, to balanced data access, or read/ write, circuitry.  By virtue of the connection of balanced bit, and bus lines, and balanced data access circuitry, to each flip-flop sense amplifier, the probability of reading errors due to circuit imbalances at the input/output nodes of the flip-flops is greatly lessened.  The direct connection, from the read/write circuitry to both parts of each bit line, arising from this arrangement obviates the need to enable a flip-flop sense amplifier in order to perform a writing operation, and permits a read-modify-write operation with flip-flop sense amplifiers designed with dynamic loads.             - i -

Abstract: ABSTRACT      Selected radio circuits are fabricated on modules which plug into a "mother" board located in the radio chassis. The circuitry included a plurality of RF front ends (including at least one AM and one FM front end), each tunable over a selected radio band by tuner circuitry.  The AM front end includes a saturable core reactor whose tuning inductance varies as a function of the tuning current provided to it by a voltage-to-current converter in the tuner.     Both AM and PM signals are translated by a frequency synthesizer to a common IF  frequency, namely 10.7 MHz. The synthesizer employs a quarts crystal controlled oscillator feeding a phase lock loop whose frequency is varied via the tuning control.  Quartz crystal filters for AM, and ceramic filters for PM provide required selectivity.  As all signals are at the same IF, a common IF amplifier is employed. Further, a single phase lock loop is adapted to demodulate both AM and PM signals.     The resultant demodulated signals are amplified, and tone shaped, via D. C. voltage controlled audio processor circuitry.  The audio circuitry is adapted to accept auxil-iary inputs, such as the output of a tape player.     A digital display senses tuner status providing fre-quency read out.  Additional provisions allow switching the display to read out tape player status, or to provide a time display from an electronic clock.

Abstract: RCA 69,160 Abstract During the integration time, the voltage applied to the electrodes of a charge coupled device (CCD) imager under which radiation induced charges are to be collected is changed as a function of time.  To obtain dark current reduction, a linear ramp may be employed which starts at a relatively low voltage level.  The lower average voltage employed to collect charge signals results in lower dark currents (especially at locations where defects are present) but does not appreciably change the number of radiation induced charge carriers which are collected.  To obtain increased dynamic range, the voltage may be changed in non-linear fashion, for example, increased in discrete steps or increased by changing the slope of the voltage waveform.          Similar techniques may be employed for gamma (.gamma.) correction.

Abstract: Abstract of the Disclosure This invention relates to the field of electronic watches utilizing liquid crystal displays and, more particularly, to means for illuminating such displays under poor ambient light conditions.  In the present invention, the output from the oscillator, which conventionally drives the dividing and counting circuits of the timepiece, is also utilized to power the light source.  The divider output is typically at a frequency of 8Hz, but frequencies in the range of from 3Hz to 100Hz may be used to drive the light source without noticeable degradation of the light output.      By using a pulsed rather than continuous direct current, the power con-sumption is significantly reduced with the attendant advantage of extended battery life.

Abstract: ABSTRACT OF THE DISCLOSURE      A gaseous medium containing aerosols is drawn through a quartz sampling tube and a filter located therein, with the aerosols becoming entrapped on the filter.  The filter is located at the geometric center of a microwave cavity, and the principle resonance of the latter is tracked with the aid of a n adaptive electronic circuit.  The time rate of change of the resonant frequency is a function of the rate of deposition of particulate matter on the filter, and principally of the liquid water content of those aerosols.  Water in the vapor phase passes through the filter and does not affect the measurement; solid particulate does affect the frequency shift but in a second order manner and is readily compensated for after measurement of total aerosol mass deposited and the determination of the dielectric constant of the solid species therein.  In a preferred embodiment a pair of microwave cavities is utilized to compare the resonant shift with the resonant frequency indicated for the same air sample after removal of the aerosol.
