Abstract: ABSTRACT           A recombinant influenza virus strain derived from (a) an over-attenuated influenza A strain which has been passaged solely in chicken egg cultures, manifests a relatively high yield of virus in such cultures and has an increased capacity for plaque formation of calf kidney cells and (b) a virulent influenza A strain which mani-fests a relatively low culture yield of virus and is sub-stantially free from contaminating mammalian viruses; a method of manufacturing the recombinant strain and a vaccine incorporating it.           The virulent strain is preferably one fairly recently isolated at the time of manufacture of the vaccine.  The over-attenuated strain should have sufficient antigenic distinction between it and the virulent strain and have a proven safety record.

Each charge comparison circuit includes an active charge comparator device having a pair of field effect transistors that are cross-coupled to one another.  Charge is applied from the output of the preceding shift register to an input of the charge comparison circuit, and the charge is compared with a reference charge developed from a reference signal The charge comparison circuit provides complementary logic output signals that correspond to whether the input charge is greater or less than the reference charge.  The charge comparison circuit is insensitive to voltage variations in the DC power supply and does not consume any DC power.  The output logic signals are compatible with the logic levels of the external circuitry.

Abstract: THROTTLE AND IGNITION ADVANCE LINKAGE FOR         AN INTERNAL COMBUSTION ENGINE  Abstract of the Disclosure The carburetor throttle valve of an internal combustion engine is set in timed relation to a timing control coil by a T-shaped throttle control lever coupled to an external throttle operator and a timing control lever resiliently coupled to the throttle control lever.  The two control levers are pivotally mounted on a common pivot pin secured to the engine block. The T-shaped throttle lever is pivotally mounted at the center of the cross-bar with a pair of throttle control cables secured to the opposite ends and to an external throttle control.  The stem of the lever projects outwardly toward the carburetor valve input element.  A cam member includes a slotted and clamp screw connection to one side of the stem to permit adjustment of the cam member along the length of the stem.  A guide wall is coupled to the other side of the stem by a T-shaped stem and groove. The cam member has a first flat cam surface spaced from the valve pin at idle and an angular oriented second surface to provide an amplified throttle movement after a timing advance limit is reached.  The timing lever extends across the cross-bar of the throttle lever with a hook end extended outwardly in laterally spaced relation to the stem.  A coil spring connects the hook end to the stem portion.  The opposite end of the timing lever is adjustably secured to the timing rod for positioning a firing coil of a capacitor discharge ignition system.  A stop screw on the timing lever limits the advance firing position of the coil. The initial rotation of the throttle control lever rotates the timing lever means to TDC and the throttle lever to just engage the valve input.  Rotation of the throttle lever for a relatively small angle then simultaneously rapidly advances the timing and slowly opens the throttle after which the timing lever engages the stop means and the throttle is advanced with fixed timing.

Abstract: ABSTRACT OF THE DISCLOSURE     TAMPER-PROOF BOTTLE CAP AND CONTAINER     An improved bottle cap and container are disclosed. The cap is composed of a top disk, a thin-walled outer skirt and a thin-walled inner skirt both attached to the disk.          The outer skirt is weakened along two circumferential score lines to form a weakened cylindrical band around the outer skirt.  A tab is attached to the cylindrical band and extends outwardly to provide a means whereby a person may grasp the tab between the fingers and tear the band from the cap.  The outer skirt also has two circumferential beads attached to the inside of the skirt with one bead being disposed above the band and one below the band.  These beads fit in groove in the container neck.  Prior to tearing the band from the skirt, the cap is tamper-proof.  When the band is removed the portion above the band functions as a reclosure cap.

Abstract: S P E C I F I C A T I O N IMPROVED HEADER ATTACHMENT STRUCTURE                    ABSTRACT OF THE DISCLOSURE      A crop harvesting header and power unit or tractor of a self-propelled windrower incorporate improved structure for attaching the header to the tractor.  The improved structure includes a saddle bracket fixed to an outer end of each of a pair of laterally spaced apart lower lift arms pivotally mounted on the forward end of the tractor and a spacer sleeve mounted to each of a pair of correspondingly spaced apart lower portions of the header.  Each header sleeve may readily be seated within a respective one of the saddle brackets on the lower lift arms by the tractor operator manipulating the position of the lower lift arms and maneuvering the tractor. The improved attaching structure further includes a front lip formed on each saddle bracket which will overlie a retaining pin insertably mounted in each respective lower header portion by the operator adjacent each header sleeve after the sleeve has been seated in its corresponding lift arm saddle bracket.  When the lift arms are pivoted upwardly or downwardly to raise or lower the header with respect to the ground,  each saddle bracket rotates about its respective spacer sleeve and moves relative to its adjacently positioned retaining pin such that the pin, in effect, follows the contour of the lower, outer surface of the saddle bracket and its lip to thereby maintain the sleeve in seated relationship with the saddle.

Abstract: Abstract of the Disclosure An improved composition and method for detecting fibrinogen, fibrinogen split products and/or fibrin split products in blood comprises utilizing killed, dyed Staphylococcus aureus cells which can be prepared by either of two methods.  In the first method, Staphylococcus aureus organisms are incubated in a nutrient medium containing a polyalkylene glycol having a molecular weight of from 1000 to 5000 to which is added triphenyltetrazolium chloride; the growing organisms reduce the triphenyltetrazolium chloride to triphenylformaran which imparts coloration to the cells; the dyed Staphylococcus aureus cells are killed and substantially all untrapped dye is removed.  In an alternate method, a suspension of Fast Black Salt K is added to a suspension of killed Staphylococcus aureus cells, and the dyed cells which result are washed to remove substantially all unfixed dye.  The killed, dyed Staphylococcus aureus cells prepared by either method are suspended in an imidazole buffer to maintain a pH of 7.4.  The suspension may be lyophilized if desired.  The determination of fibrinogen split products and/or fibrin split products in blood serum is performed by serially diluting the blood serum test sample and adding a specified volume of reconstituted killed, dyed Staphylococcus aureus cells to an equivalent volume of each serial dilution of serum test sample, and observing the serial dilutions for the presence of visible clumping as a positive test result.  Coloration of the cells greatly improves visualization of the end point of the test.  The concentration of fibrinogen split products and/or fibrin split products in the blood serum test sample can be calculated if a comparison test is run with a serum containing a known amount of fibrinogen, fibrinogen split products and/or fibrin split products.

Abstract: ABSTRACT         An austenitic stainless steel alloy which has extremely good pitting resistance and at the same time has good hot-workability characteristics. The alloy contains, as essential constituents, chromium, nickel, molybdenum, calcium and cerium. In achieving the desirable characteristics of the invention, the molybdenum and chromium levels are important in determining pitting resistance; while recoveries of cerium and calcium in the final alloy are important in determining the hot-workability of the alloy, although cerium is the more impor-tant of the two. Sulfur levels are preferably maintained low, on the order of .006% or less.     Also disclosed is a method for making an alloy of the type described above wherein the finishing temperature of hot-rolled strip is maintained around or above 1800°F to reduce edge cracking and preferably is maintained at about 2000°F.
