Abstract: ABSTRACT          SMOKING ARTICLES AND METHOD OF MAKING SUCH ARTICLES          A smoking article (15) comprises a coherent mass (9) of combustible tobacco-containing material having at least one passage extending through it between two spaced openings in the surface of the mass, the tobacco mass having such porosity as to support combustion when ignited and such density and porosity as to substantially occlude gas flow therethrough.  The article preferably has at least one air-permeable plug (5,6) of readily ignitable material blocking the passage at one or both ends.  The tobacco-containing mass may include non-tobacco filler particles, such as carbon or clays, and the plug may contain a flavorant.  The articles may be made by shaping a mixture of combustible tobacco material with a volatile liquid, for example a mixture of water and ethanol, under pressure into a discrete coherent mass, preferably by extrusion, forming a passage through the mass, and drying the mass to a porosity and density such as to substantially occlude gas flow therethrough but to support combustion when ignited.

Abstract: ON-HOOK/OFF-HOOK STATUS CHECK CIRCUIT          Abstract of the Disclosure_ An off-hook/on-hook status check circuit is adapted to be connected in series with either the tip or the ring lead of a telephone subscriber loop at a location remote or apart from the telephone station set.  The circuit comprises an opto-emitter subcircuit in series with a capacitor.  These are connected in parallel with a pulsing contact which alternately permits the charging of the capacitor by the telephone central office voltage or its discharge through the opto-emitter subcircuit.  As the capacitor may only be charged when the telephone station set is off-hook drawing loop current, the opto-emitter subcircuit provides a predetermined output when the capacitor discharges, identifying the off-hook condition of the telephone station set.  No output from the opto-emitter subcircuit during the capacitor discharge interval identifies the on-hook condition of the set.  If the present circuit comprises an element of a dial pulse signaling system, the dial pulse signaling system is able to abort dial pulsing when the telephone set is on-hook and continued dial pulsing is not desirable.

Abstract: ABSTRACT OF THE DISCLOSURE      A cord locking device is provided for use in association with a sun-blind or the like provided with an upper beam and one or more webs of sun-blinding material folded in a zigzag line and opened or closed by means of cords.  The locking device has a U-shaped member having a flat bottom and legs, with a cross-plate at one end having an inlet hole to accommodate a number of cords.  Also included in the assembly is a tumbler with a pivot shaft near its upper end, which pivot shaft is journalled in the legs of the U-shaped member near the tops of the legs.  The tumbler, in vertical position, substantially fills the space between the legs and bottom of the U-shaped member under the pivot axis, and the lower edge of the tumbler is spaced from the bottom by a distance smaller than the thickness of the cords, which should extend between the bottom and the lower edge.  The tumbler is loaded by a member which is slidable in the cross-plate in vertical direction, and this slidable member projects a lip or the like, the free end of which may cooper-ate with the adjacent face of the tumbler to effect loading. In a portion of the slidable member, which is lying in the cross-plate, an inlet hole for the cords is provided substan-tially coinciding with the inlet hole in the cross-plate, whereby the bottoms of the inlet holes are at least partly sloping upward in opposite direction.  In this way, a cord locking device is provided which will be operative for use with sun-blinds, yet can be made smaller than locking devices previously known that it can be built into an endstop of the blind, or can be affixed externally with minimal defacement.

Abstract: METHOD AND APPARATUS FOR                  MONITORING LUNG COMPLIANCE                     Abstract of the Invention Respirator techniques are described for measuring the linear slope of the inspiratory phase to monitor lung compliance.  The measurements of the slope characterize a pressure wave index which is recorded at regular intervals to provide a clear record from which a warning of the patient's pulmonary condition such as lung compliance can be derived.  Several techniques are shown and described.   In one, the pressure wave index is determined by sensing the times when the pressure-time signal reaches predeter-mined pressure levels above a base line.  In another technique, the linear slope segment is searched for and its slope then measured.

Abstract: ABSTRACT OF THE DISCLOSURE            A power transistor array integrated circuit includes an array of transistors, each having an electrode connected in common to a conductive line forming a part of the integrated circuit.  The electrodes of the trans-istors are spaced along the conductive line and have a decreasing length in a given direction along the conductive line and have a decreasing length in a given direction along the conductive line.  The conductive line has a corresponding increasing width in the given direction.     The decrease in length of the electrode and the increase in width of the conductive line are such that the electrodes and the conductive line form a generally rectangular shape.  Differences in turn-on voltage for the transistors resulting from the differences in their elec-trode length tend to compensate for voltage drop in the conductive line, thus giving uniform outputs from the trans-istors in the array.  A region forming a reverse biased P-N junction to isolate circuit elements in the integrated circuit from one another is used as part of a conductive path to circuit ground and has a surface contact region of like conductivity and more highly doped than the reverse biased P-N junction region. The integrated circuit of this invention is especially useful as a thermal print-head driver circuit.

Abstract: ABSTRACT OF THE DISCLOSURE The primary winding of a high leakage inductance transformer is coupled to a source of alternating input voltage to develop alternating polarity output voltages across tightly coupled secondary windings, including a high voltage winding of the transformer.  Various DC supply voltages, including the ultor voltage, are derived from the secondary winding output voltages.  To regulate the secondary winding output voltages, a          circuit comprising a capacitor and a saturable reactor is coupled as a load circuit to one of the transformer secondary windings. When the saturable reactor magnetically saturates during each half cycle of the alternating polarity output voltage, a circulating current is generated and flows between the saturable reactor and the capacitor.  To enhance the power supply efficiency and reduce the temperature rise within the magnetizable core of the saturable reactor, the parameters of the transformer and               load circuit are selected so as to generate a relatively low amplitude circulating current.  To improve output voltage regulation when a low amplitude circulating current is developed, a compensating drive winding is provided that is magnetically tightly coupled with the primary winding of the high leakage transformer.  The compensating drive winding is coupled in series with the saturable reactor winding across the capacitor and polarized relative to the capacitor coupled transformer secondary so as to oppose the tendency of the output voltage amplitude or half-cycle volt-second area to vary with variations in input voltage amplitude.

Abstract: REDUCTION OF NITROGEN OXIDE   EMISSIONS FROM CALCINERS     ABSTRACT OF THE DISCLOSURE     Disclosed are method and apparatus for reducing the emissions of nitrogen oxides from incineration systems.    More particularly, the invention relates to the reduction of nitrogen oxide emissions from thermal incinerators employed in installations for calcining solid carbonaceous materials such as petroleum coke and anthracite coal.  A hot effluent gas stream containing hydrocarbon vapors and entrained carbonaceous solid particles is removed from a calciner and introduced into a thermal incinerator for combusion of the vapors and the particles.  The improvement comprises effecting preliminary combustion of the hydrocarbon vapors but not the carbonaceous solid particles in the gas stream using sub-stantially the stoichiometric amount of combustion air, and introducing the resultant gas that is substantially free of hydrocarbons and oxygen into the thermal incinerator and therein effecting combustion of the carbonaceous solid particles with additional combustion air, thereby to reduce the nitrogen oxide emissions from the incinerator.
