Abstract: TITLE            PROCESS FOR REDUCTION OF NITRATE AND NICOTINE CONTENT OF TOBACCO BY MICROBIAL TREATMENT                        INVENTOR                      Vernon Louis GEISS, Lawrence Edmond GRAVELY and Charles Fred GREGORY     A process for the reduction of the nitrate and nicotine contents of tobacco by microbial treatment is disclosed wherein tobacco materials are subjected, under controlled conditions, to the action of a microorganism effective to degrade nitrates and alkaloids (nicotine) through a biochemical reaction. The microorganism is combined or grown in the presence of a nitrate containing compound in relatively small quantities.  Tobacco treated in accordance with this process has a reduced nitrate and nicotine content, and when incorporated into a tobacco smoking product thereby produces a mild smoke, having reduced nitrogen oxides, hydrogen cyanide and nicotine content.  However, there is no loss of desirable flavor, taste and smoking properties.

Abstract: POKE-THROUGH ELECTRICAL FITTING WITH RELEASABLE WEDGING POINT FOR RETENTION     Abstract A poke-through electrical fitting device for place-ment in a passageway such as a cylindrical hole through a wall, floor, or the like, which may be made of concrete or some other fire rated barrier.  The fitting is designed to prevent the spread of fire from one side of the fire rated barrier to the other, to protect the conductors and to facili-tate installation, by requiring minimum disassembly or assembly during the installation which may be accomplished by a single craftsman.  The fitting includes a channel member through which the conductors pass.  Pivotally coupled to the channel member are spring biased wing members which extend laterally and which include wedge points for binding engagement with the interior of the passageway.  The wing members and wedge points may be released from the underside to facilitate removal of the fit-ting.  A thermal barrier is included to inhibit heat transfer, and other sealing members are provided as a barrier to any products of combustion.  The fitting may include a divider to allow multiple classes of wiring.  A sliding collar assembly may be used at the lower end of the fitting to provide an auxiliary fire barrier at the lower limit of the passageway or hole.

Abstract: 48,628 A B S T R A C T "FLUORESCENT LAMP" Conventionally, the inside surfaces of fluorescent lamps are known to be coated with two layers of fluorescent material. The manufacture of such lamps, however, requires two coating operations, and the red-emitting fluorescent material of the first layer has a low luminous efficiency, and the light emitted by the second layer is partially absorbed by the first layer.          In order to overcome these problems, a fluorescent lamp is provided which comprises a discharge tube on an inner surface of which there is a single layer comprising an alkaline earth metal boron phosphate containing a divalent europium compound as an activator together with a second fluorescent material which has an emission peak in a wavelength range of 620 to 640 nm and a band width (50%) of 120 to 160 nm.

Abstract: LUMBER DEFECT POSITION SCANNER            Abstract of the Disclosure In a lumber inspection and optimization system, an electro-optical defect position scanner is combined with a voice recognition device to enable a human inspector to locate and classify flaws on the surface of a board.  The human inspector, by means of an indicator, pierces a light curtain to electro-optically locate a flaw.  The indicator can be used to enhance the flaw by physically marking the board.  With voice recognition, the human inspector can vocally classify the flaw.   These voice classifications are later correlated with flaw information and used to process the board into its finished products.

Abstract: COMBUSTION APPLIANCE WITH SAFETY DEVICE          Abstract of the Disclosure The invention relates to a combustion appliance having a safety device.  The appliance comprises an inner flame cylinder, a red-heat cylinder and an outer cylinder disposed concentrically outside the red-heat cylinder, thus forming a combustion chamber.  An oxygen sensor is located at a position where it will directly encounter the hot exhaust gases from the combustion flames of the combustion chamber and in a position where the excess air ratio of the flames can be detected.  The oxygen sensor is a partial oxygen pressure sensor in which the resistance between a pair of spaced electrodes changes with variations in the partial oxygen pressure of the atmosphere to be detected.  During incomplete combustion caused by an air feed shortage or the like, e.g. due to dust clogging or the like as well as during the oxygen depression, the oxygen sensor can detect changes in the flames or changes in the red-heat condition of the red-heat cylinder to stop the burning operation thereby to secure the safety.

Abstract: ABSTRACT OF THE DISCLOSURE           Disclosed is a horizontal drive system and method for operating a video display capable of precisely controlling over a wide timing range the interval between the arrival of the leading edge of the input drive pulse and the initiation of the flyback pulse thus permitting the horizontal output to the video display to be synchronized to a great variety of horizontal drive input signals.  The leading edge of the horizontal drive pulse triggers a variable time delay monostable multivibrator, the locked output signal of which is coupled to a precision astable multivibrator.  Potentiometer adjustment of the monostable multivibrator provides for adjusting video information position with respect to raster scan while the astable multivibrator acts as the oscillator in synchronizing horizontal sweep circuitry to the horizontal input drive signal.

Abstract: ABSTRACT OF THE DISCLOSURE          Poly(ethylene terephthalate) filaments of enhanced dyeability, low boil-off shrinkage (even in as-spun condition), good thermal stability over a large temperature range, and useful as texturing feed yarns and/or as hard yarns requiring no further drawing are prepared by spinning at a withdrawal speed (V in yards/minute) of at least about 5500 yards/minute and with a polymer temperature (Tp) measured (in °C) in the filter pack at a point 50-100 mils above the center of the spinneret plate of   wherein (L) and (D) are the length and diameter (in mils) of the spinneret capillary and (w) is the throughput (in pounds/ hour) per capillary.  The filaments are characterized by a long period spacing above 300 .ANG. in their as-spun condition, and, whether in as-spun condition or after heat-treatment, by a low skin-core value as measured by a differential birefrin-gence in relation to their stress measured at 20% extension (which correlates approximately with the spinning speed), a large crystal size, and low amorphous orientation.  The continuous filament yarns may be draw-textured to provide textured yarns which also show enhanced dyeability.  The staple fiber yarns also have very useful properties as compared with conventional staple yarns.  A preferred process of spinning at these extremely high speeds is characterized by the use of a spinneret with capillary-dimensions that produce high shear as the polyester is extruded and is applicable also to copoly-esters, whose filaments show a similar low skin-core in relation to their stress at 20% extension, the precise values for copoly-mers being different from the relationship for poly(ethylene terephthalate).

Abstract: ABSTRACT   The present invention relates to means for transporting/rotating the pot of a smelting furnace. The invention is particularly adapted to furnaces having rotating furnace pots and in particular to furnaces with a split furnace body. The pot is locked from rotation simply by letting the furnace pot rest on its foundation during intervals in which the pot is supposed to be at rest. The pot is rotatably arranged with respect to the furnace foundation and the rotation is produced by means of a plurality d transport means. The transport means are preferably evenly arranged around the circumference of the pot. The transport means comprises lifting means which periodically lift the pot partly or completely off its foundation. The lifting means are preferably of a type which provide a lifting force in vertical direction, either by means of a hydraulic medium or compressed air. The lifting means may for example be formed by one or more flexible hoses which communicates with a pressure producing source. According to the present invention the resistance of rotation imposed by the charge material may provide rotation of the pot, said resistance being exploited to transfer rotation from the upper section to the lower section of the pot.
