Abstract: ABSTRACT OF THE DISCLOSURE       A waterproof article for use in, for example, protective clothing.  The article prevents liquid water from penetrating through to undergarments while at the same time permitting moisture vapor such as perspiration to pass out through the article.  The article is thus both breathable and waterproof, The article is layered:  a microporous hydrophobic outer layer which permits the passage of moisture vapor but resists pene-tration by liquid water at pressures up to about 50 psig;  a hydrophilic inner layer permitting the transfer of moisture vapor but preventing surface tension lowering agents such as those contained in perspiration and/or body oils from reaching the hydrophobic layer.

Abstract: RCA 73,648 Abstract of the Disclosure Apparatus is disclosed in a video signal processing system for automatically controlling the blanking (black) current level of an image reproducing kinescope having cathode and grid intensity control electrodes.  During measuring intervals when cathode blanking current is to be monitored, a fixed voltage is applied to the cathode over the entire measuring interval, and a locally generated auxiliary signal is applied to the grid electrode during a portion of the measuring interval.  A version of the grid signal appears as a cathode output signal proportional to the level of cathode blanking current conduction.  A voltage responsive sensing network coupled to the cathode provides an output difference voltage proportional to the difference in cathode current conducted over the measuring interval. This voltage is utilized to modify the cathode bias in a direction to produce the desired cathode blanking current level at or in the vicinity of kinescope cut-off.

Abstract: Abstract A receiving system is disclosed that substantially instantaneously receives an RF signal.  The inventive receiving system may be advantageously utilized at a central station of a mobile radio system for providing an omnidirec-tional receiving pattern.  Both voice and digital information signals modulated on the RF signal transmitted from a mobile station are substantially instantaneously acquired by the central station.  The receiving system includes an omnidirectional antenna array having a plurality of spatially disposed directional sector antennas, converting circuitry for converting the RF signals received by each directional sector antenna to an IF signal, IF bandpass filters for filtering each of the IF signals, and a maximal-ratio predetection diversity combiner for continuously combining the filtered IF signals to provide a composite IF signal so that any received RF signal is substantially instantaneously acquired.  Because of the fast acquisition of RF signals, the receiving system will not lose the initial portion of voice and digital information signals modulated on an RF signal transmitted by a mobile station.

Abstract: Method And Apparatus For Purification of Gases Abstract The present invention is directed to a method for selective purification of gases. The method comprises feeding an exhaust gas containing a solid impurity and a gaseous impurity to a separator. A substantial portion of the solid impurity is separated. Then, the partially-purified gas is fed to a spray dryer. That gas is sprayed with an absorption agent to separate gaseous impurities. Then, the further, partially-purified gas is fed to another separator to separate remaining solid impurity. An exhaust gas which is substantially free of solid and gaseous impurities and fly ash having a desired quality are recovered. The invention is also directed to an apparatus for selective purification of exhaust gas, containing solid and gaseous impurities, from a boiler plant (1). The apparatus comprises a solid-separation means (3) for separating a substantial portion of the solid impuri-ties from the exhaust gas. Then, a means for feeding the partially purified exhaust gas to a spray-drying means (5) is included for separating gaseous impurity from the exhaust gas. Then, a means for feeding the further, partially-purified exhaust gas to another solid-separation means (7) follows the spray-drying means. A plant for selective removal of fly ash and sulphur oxides from boiler plant exhaust gas is also described.

Abstract: Shear Seal Assembly Abstract A shear seal assembly has an inner sleeve and an outer sleeve with an elastomeric material bonded therebetween.  One sleeve has a circumferential groove formed in the exposed wall thereof in which groove an O-ring nests.  The assembly is mounted between two telescoping members that have limited relative rotation. The sleeve without the groove is press fit on or in one member and the sleeve with the groove will be spaced from the other member so that the O-ring will extend from the groove into sealing contact with said other member.  Clips or retainers are provided for seating the grooved sleeve to said other member whereby limited relative rotation or oscillation between the members takes place without rupturing the elastomeric material.  The shear seal can be removed without destroying the shear seal structure so that it can be reused.

Abstract: ABSTRACT       Electronic Measuring Apparatus Electronic measuring apparatus, specifically for measuring the fuel consumption of a vehicles is arranged to receive distance indicative signals from a speed sensor and rate of fuel flow signals from a flowmeter sensor.  The values represented by these signals are then divided by suitable processing means, such as a microprocessor, and the resulting output signal provides an indication on a display of fuel consumption with respect to distance travelled.  A manually activatable calibration circuit causes storage of the value of the speed-dependent signal at the moment of manual activation and the microprocessor makes use of this stored reference value as a weighting factor for the calculation of fuel consumption.  Accordingly it is arranged that the manual activation of the calibration circuit should take place at a predetermined speed, and thenceforth other speeds are calculated on the basis of the predetermined speed corresponding to the value of the speed-dependent signal at the moment of activation of the calibration circuit.
