Abstract: TRANSFER AND ADHERENCE OF RELATIVELY DRY PAPER WEB TO A ROTATING CYLINDRICAL SURFACE     Gregory A. Bates ABSTRACT OF THE DISCLOSURE           In manufacturing a soft and absorbent tissue paper, a moist web deposited from a fiber-water slurry, is contoured with the pattern from an open mesh conveying fabric and thermally dried to a relatively high fiber consistency.          Following these steps, the resulting relatively dry patterned web is imprinted as it is transferred and adhered to a rotating cylindrical surface in the form of a Yankee dryer utilizing an aqueous polyvinyl alcohol solution where the polyvinyl alcohol is characterized by a particular degree of hydrolysis and particular viscosity characteristics.  By thermally drying to a high fiber consistency prior to the transfer step, the amount of drying load required to be carried by the Yankee dryer is reduced resulting in either (1)   increased line speed as a result: of reduced Yankee drying load, which reduces the required residence time of the web on the dryer or (2) a reduction in the required diameter of the Yankee dryer, a significant reduction in capital equipment cost.  By thermally drying the web to a relatively high consistency on the conveying fabric, a deeper more pronounced pattern in the Z direction is obtained due to an increase in web structure strength and resistance to compaction of the pattern.  This results in increased bulk (lower density) and increased softness.  As a result of utilizing the particular polyvinyl alcohol, transfer and adherence of the relatively dry web to the Yankee dryer is obtained so as to minimize the amount of skipped crepe whereby the problem of web breakage downstream of creping is eliminated.

Abstract: ABSTRACT OF THE DISCLOSURE         Upper and lower parallel arms are pivoted to the frame of the implement and extend therefrom.  A shank carrying crank member is pivoted intermediate the ends to the outer end of the lower arm and by the upper end to a link which in turn is pivoted to the outer end of the upper arm.  An adjustable heavy duty ten-sion spring extends between the parallel arms intermediate the ends thereof.  When the arms are raised and lower, the shank and culti-vator element carried thereby moves substantially vertical and re-mains in the same horizontal attitude due to the parallel arms.    When an obstruction is engaged by the cultivating element, the crank pivots on the lower arm thus forcing the upper arm upwardly and extending the spring.  The link goes over center thus facili-tating the tripping action if the obstruction is relatively large and further extends the spring which returns the cultivating ele-ment to its original position after the obstruction has been passed.

Abstract: REGENERATIVE-CYCLE INCANDESCENT LAMP       CONTAINING HgBr2 ADDITIVE              ABSTRACT OF THE DISCLOSURE         The useful life of high-efficiency type bromine-tungsten cycle incandescent lamps, such as those used in TV-studio and theater lighting applications, is enhanced by dosing the lamps with a carefully controlled quantity of mercuric bromide (HgBr2) which dissociates when the filament of the finished lamp is energized and provides a predeter-mined amount of Br2 within the envelope during lamp operation.          The quantity of HgBr2 dosed into the envelope is adjusted according to the design life and initial efficiency parameters of the specific lamp type so as to provide a concentration of Br2 within the envelope which is correlated with such parameters and prevents blackening of the envelope and pre-mature failure of the filament at the particular "life-efficiency level" of operation for which the lamp is designed.          For a 1000 watt 120 volt tubular incandescent lamp (DXW type) having a design life of 150 hours and an efficiency of 28 LPW, the HgBr2 dosage is such that it provides from about 2.5 to 6 torr of Br2 within the lamp during operation ---whereas a lamp of the same wattage and voltage rating designed to operate for 50 hours at 33 LPW (DXN type) is dosed with a slightly larger quantity of HgBr2 to provide from about 3.5 to 8.5 torr of Br2 within the operating lamp.

Fiber optics form an optical pathe from the illuminating means to the document and from the document to the photodetector means with filter means being located in the optical path for attenuating light in the near infrared region of the spectrum. Amplifier means are coupled to the photodetector Means and automatic gain control means are associated with the amplifier means for increasing the gain of the amplifier in response to a lesser amount of light detected by the photodetector. The gain control means is adjustable so as to limit the increase in gain when detecting dark regions. Lead networks are coupled to the amplifier means to increase the speed of response to dark-light variations in the document.

A small relatively higher velocity stream of air is directed concentric about a divergent spray or stream of ignited fuel oil in a primary flame zone in such amount that only a minor portion of the fuel can be combusted in said primary flame zone.  The air is directed in such manner as to produce toroidal fluid circulation pattern atomizing the liquid fuel and establishing a stable flame.  A small amount of recir-culated flue gas (RFG) is immediately thereafter introduced concentrically about said primary flame zone in the general direction of fluid flow.  Air is introduced concentrically thereabout in a secondary flame zone in the fluid flow path of said primary flame zone in at least sufficient quantity to burn the remaining combustibles.  Oxides of nitrogen in the resultant effluent are suppressed by adjusting the amount of RFG and hence the flame composition and tempera-ture.
