Abstract: ABSTRACT OF THE INVENTION           A cigarette holder is disclosed which contains a filtering element in a cavity within the barrel of the holder.  The filter element is provided with a flange that extends from the element and divides the cavity into an upstream filtering chamber and a downstream stor-age and filter chamber.  Conformations in the flange per-mit communication from the upstream to the downstream side of the cavity.  Smoke enters the filter cavity through a restricted opening where it is made to pass at high velo-city.  Thereafter, the smoke is permitted to expand and cool such that the tars and nicotine in the smoke are con-densed.  The chamber and the filtering element are arranged so that the smoke swirls to impart a kinetic energy to the condensate which results in an inability to follow the con-formations past the flange whereby the condensate is made to impinge upon the surfaces of the filter element where it is condensed.

Abstract: Abstract of the Disclosure A closed-loop emission control apparatus for internal combustion engines includes exhaust composition sensor for feedback control of the air-fuel mixture.          When the temperature in the exhaust passage is lower than the operating temperature of the sensor, control is switched to an open-loop mode.  The feedback control signal is fluctuated above and below a predetermined DC bias at periodic intervals during the open-loop mode to switch the control to the closed-loop mode in a minimum transition time as soon as the sensor's temperature condition warrants feedback control.

Abstract: THERMAL HYDROCRACKING OF HEAVY HYDROCARBON        OILS WITH HEAVY OIL RECYCLE           Abstract of the Disclosure An improved process is described for the hydro-cracking of heavy hydrocarbon oils, such as  oils extract-ed from tar sands.  The heavy hydrocarbon oil feedstock in the presence of an excess of hydrogen is passed through a confined hydrocracking zone under upflow liquid cond-itions, and the effluent emerging from the top of the hydrocracking zone is passed into a hot separator where it is separated into a gaseous stream containing hydrogen and vaporous hydrocarbons and a liquid stream containing heavy hydrocarbons.  The hot separator is maintained near the temperature of the hydrocracking zone and the effluent from the hydrocracking zone enters the separator in a lower region below the liquid level in the separator.  The gaseous stream containing hydrogen and vaporous hydrocarbons is withdrawn from the top of the separator while a portion of the liquid phase in the separator is recycled to the hydrocracking zone without further treatment and in quantities sufficient to increase the superficial liquid flow velocity in the hydrocracking  zone such that deposition of coke in the hydrocracking zone is sub-stantially eliminated.

Abstract: DECONTAMINATION OF WET-PROCESSED PHOSPHORIC ACID. ABSTRACT OF THE DISCLOSURE: Wet-processed phosphoric acid is decontaminated. To this end, the phosphoric acid and an organic solvent, which is partially miscible with water and capable of absorbing phosphoric acid, are contacted countercurrently with respect to one another. The resulting organic phos-phoric acid solution is separated from contaminants un-absorbed by the solvent, termed primary raffinate, decon-taminated phosphoric acid is recovered either in the form of free acid by re-extracting the organic phosphoric acid solution with water, or in the form of an alkali metal phosphate by reacting the organic phosphoric acid solu-tion with an alkali, and the primary raffinate is treated countercurrently with a solvent containing a mineral acid. More specifically, the organic phosphoric acid extract, which originates from the primary raffinate treatment and contains more than 0 up to at most 10 weight% of water, is mixed with an anhydrous solvent in a ratio by weight necessary to ensure the formation of a mixture containing more than 0 and less than 50 % of water than would corres-pond to the saturation concentration of water in the sol-vent; and the mixture is contacted countercurrently with the phosphoric acid which is to be decontaminated.

Abstract: ABSTRACT OF THE DISCLOSURE             The present invention is directed generally to electrical connectors and, more particularly, to improved modular connectors and associated bridging adapter assemblies which may be, for example, advantageously applied in the interconnection of individual telephone receivers to telephone system equipment. The proliferation of different species of telephone connector hardware has required that technicians be familiar with the peculiarities and wiring requirements for a maze of adapters and connectors and that the telephone companies maintain cor-respondingly large part inventories. The telephone companies have focused considerable emphasis on the development of standardized or modularized telephone cables, connectors and associated adapters. The modular connectors and their associated adapters must be creatively designed to provide a wide ranging flexibility in the interfacing with existing telephone system equipment, as well as a suitability for new installations, while retaining simplicity in installation and a rela-tively modest initial manufacturing cost. The present invention is directed to a modular connector which meets the aforementioned require-ments, and to novel adapter assemblies which allow the novel modular connector to be utilized in a wide variety of system applications. According to the present invention, the modular connector and a mounting plate are structured so that the connector sidewalls with integral bosses and/or the apertured mounting plate are resiliently deformable to permit simple insertion and snap-locking of the connector and mounting plate. Various adapter configurations utilizing one or more modular connectors in unique system arrays for interconnection to non-mating signal equipment are also disclosed.

Abstract: Docket No. PC-996 ABSTRACT    Disclosed is a circulation valve for use in the testing of an oil well wherein the circulation valve may be reclosed by application of well annulus pressure to allow a subsequent treating or testing program.  A spring means is subjected to well annulus pressure on two ends of a volume of fluid. The volume of fluid is divided by a dividing means which includes pressure relief means such that fluid on one side of the dividing means is either higher or lower than the well annulus pressure.  This dif-ferent pressure is applied to one set of a piston means, and the other side of the piston means is subject to well annulus pressure such that movement of the piston means may be controlled by changing the well annulus pressure.          An indexing means is additionally disclosed which controls opening of the circulation valve after a selected number of piston means movements, and which closes the circula-tion valve upon a selected movement of said piston means when the circulation valve is in the open condition.
