Abstract: ABSTRACT OF THE DISCLOSURE         A ultrasonic flaw detector device including axial and circumferential fixed tracks located in a space defined between a pressure vessel of a nuclear reactor and a heat insulating wall surrounding the vessel and arranged axially and circumferentially respectively of the pressure vessel of the nuclear reactor.  A rotary track is located at a junction of the axial fixed track and the circumferential fixed track and moved in rotary movement by a chain and has its angle of rotation restricted by a pair of stoppers.  A carrier member supporting a ultrasonic probe is moved on the tracks to effect ultrasonic flaw detection to detect any flow that might be present in the pressure vessel.  To transfer the carrier member from the axial fixed track to the circumferential fixed track, the carrier member is first transferred from the axial fixed track to the rotatable track, and after the rotary track is rotated, the carrier member is transferred from the rotatable track to the circumferential fixed track.

Abstract: ABSTRACT OF THE DISCLOSURE:           Two vector components of the EM field, e.g., Hy and Ex, are picked up by suitable probes.  The resulting signals are filtered by narrow band pass filters around a center frequency and amplified by gain selectable amplifiers to an acceptable level for a pre-processing circuit which enables fast mathematical operations to be done.  The pre-processing circuit uses an all pass quadrature (90°) phase shifter, four fast multipliers and four integrators under the control of a timing circuit.  The output of the pre-processing circuit are converted to digital values to permit mathematical processing.  Then, the ratio, the phase shift and the coefficient of coherence between the two vector components of the MT-EM field are calculated.  The above operations can be repeated for various frequencies .omega.o.  The coherence value gives an indication of the quality of the measurement.  With a low coherence value, the measurement must be repeated because the noise is too high.  A graph of the ratio and phase shift values of the EM field with respect to .omega.o enables a geophysicist to make an interpreta-tion of deep rock conductivities at various depths.

Abstract: METHOD AND APPARATUS FOR DETECTING AN EDIT POINT               ON A RECORD MEDIUM                   ABSTRACT OF THE DISCLOSURE         An edit point, such as a splice edit point on a record medium of the type having data recorded in at least one data track and a periodic control signal recorded in a control track, is detected.  The periodic control signal includes an address signal for identifying recurring intervals on the record medium, with data being recorded in the data tracks in successive ones of such recurring intervals.  The address signal normally is incremented from one interval to the next.  Upon repro-duction, the address signal is reproduced, and successive predictive address signals are generated, from one interval to the next, as a function of at least an initial one of the reproduced address signal.  When an address signal reproduced in an interval differs from the predictive address signal generated for that interval, the occurrence of the splice point is detected.                       -i-

Abstract: ABSTRACT OF THE DISCLOSURE      A constant velocity ratio universal joint of plunging type,  with  an  outer  joint  member  having  a  cylindrical interior and grooves formed therein, an inner joint member with a convex surface and  grooves  therein,  balls  in  the grooves, and an annular ball cage engaging the convex surface of the inner joint member and the cylindrical interior of the outer joint member.  When plunge occurs, the balls skid along the  grooves  in  the  outer  joint  member.   The  engagement between the inner joint member and cage is such that the cage can move axially to a limited extent relative to the joint member, so that at the start of plunging movement the balls are able to roll for a short distance before they skid.  This reduces the resistance of the joint to the commencement of plunging movement.   The movement between the inner joint member and cage is obtained by having their engaging surfaces curved but of different radii.

Abstract: ABSTRACT     Feedstocks of fused polynuclear aromatic hydrocarbons, such as phenanthrene, anthracene,  fluorene, and mixtures thereof, are converted to fluorenone and biphenyl products by a catalytic oxycracking step using oxygen-containing gas and steam.  Reaction conditions used are 700-1250°F temperature and 5-50 psia pressure.  The process can utilize either a single oxycracking zone containing a bifunctional catalyst, or two reaction zones connected in series each containing a single functional catalyst.  If desired, the intermediate products of fluorenone and biphenyl can be thermally hydro-cracked to produce additional benzene.  Raw hydrocarbon feed materials having a normal boiling range of 500-900°F can be treated by hydrodealkylation to provide the fused polynuclear aromatic feedstock to the catalytic oxycracking step.  Also, intermediate products from the oxycracking step are preferably hydrocracked in the same hydrodealkylation step to produce benzene product.  The catalyst composition which is utilized comprises a mixture of at least one Group IIB metal oxide and an oxide of molybdenum or vanadium deposited on a .gamma.-alumina support.

Abstract: APPARATUS AND METHOD               FOR MEASURING BLOOD PRESSURE     ABSTRACT OF THE DISCLOSURE     A blood pressure measuring device is disclosed which uses an inflatable cuff to apply external pressure to a patient's body member.  The device detects and measures amplitude of pressure oscilla-tions induced in the cuff by blood flow in the body member as the cuff pressure is decreased in steps from a magnitude above the expected systolic pressure to a magnitude below the expected diastolic blood pressure.  The mean arterial blood pressure is measured at the step at which the pressure oscilla-tions reach a maximum.  Systolic blood pressure is determined by making a first linear approximation to a plurality of amplitude measurements occurring below the expected systolic pressure and making a second linear approximation to a plurality of points occur-ring above the expected systolic pressure.  The syst-olic pressure is calculated by setting the two approximations equal.  Diastolic blood pressure is determined by detecting the cuff pressure which results in an equivalent oscillation magnitude to that determined for the systolic pressure.

Abstract: ABSTRACT OF THE DISCLOSURE           A method is disclosed for the selective removal of basic nitrogen compounds (BNC) from natural and synthetic hydrocarbon feedstocks, which method comprises mixing the feedstock oil with a nonaqueous solution of anhydrous non-polymeric Group IVb, Group Vb, Group VIb, Group VIIb, the non-noble (iron group) metals of Group VIII. copper, zinc, cadmium, and mercury halides, except chlorides, or tetrafluoroborates, complexed with non-aqueous polar sol-vents under conditions of agitation and mild heating whereby the basic nitrogen compounds exchange with the polar sol-vent to complex with the above-recited metal halides and metal tetrafluoroborates.  The oil is then decanted to separate it from the metal halides:  BNC complexes and the decantate washed with a polar solvent, which preferably in-cludes water, and dried.  The basic nitrogen compound-metal halide or metal tetrafluoroborate complex dissolves in the polar solvent, and that which is in the oil is removed by the polar solvent wash.  The preferred polar solvent for the wash step is water.     The anhydrous nonpolymeric metal halide or metal tetrafluoroborate-nonaqueous polar solvent complex can be used as such, or they can be impregnated onto a support material.

Abstract: Abstract An expansion joint sealing assembly of the type employing a flexible membrane extending between two relatively rigid elongated elastomeric pads is adapted to seal the gap in the area where a curb and roadway portion of the deck intersect. The assembly is especially useful in situations where the gap extends at a skew angle across the roadway, so that the line of intersection between the curb and roadway portions of the deck, along which the sealing assembly must be bent, is not perpendicular to the longitudinal dimension of the sealing assembly.  This creates a complex bending angle for the flexible membrane portion of the seal.  In brief terms, the problem is solved by providing laterally extending convolutions in the side edge portions of the membrane and a locking rib on the top of each convolution which fits into an appropriate slot in the elastomeric pad to which each side edge portion of the membrane is connected.

Abstract: METHOD OF USING HIGH CONCENTRATION   SULFURIC ACID FOR STRIPPING AND PRECIPITATION OF ADSORBED MAGNESIUM                         ABSTRACT      Adsorbed magnesium is removed from a cation exchange resin by elution with 20 to 70% sulfuric acid as increments of the loaded resin move upwardly in a stripping column, the regenerated resin being removed at the top of the column and the sulfuric acid of reduced concentration with the eluted magnesium is removed from the lower portion of the column.  The sulfuric acid concentrations are controlled so that the regenerating solution can be formed from commercial concentrations of sulfuric acid without undue dilution, and so that the magnesium can be precipitated from the eluting solution by increasing the sulfuric acid concentration without adding a large amount of commercial concentration acid.  The amount of dilute sulfuric acid produced as a waste material is kept to a minimum, while the prinicpal sulfuric acid by-product has a usefully high concentration, such as may be employed for treatment of phosphate rock.

Abstract: MULTIPLEXED HAMMER DOT BAND MATRIX PRINTER          Abstract The present invention describes a dot band matrix printer in which the pitch of the dot font elements on the moving band is precisely twice that of the pitch between hammer faces.  A hammer bank is positioned for impacting the dot font elements and driving them into a printing medium.  The pitch between two dot font elements is normally assigned to a single hammer, but in the present invention, the number of hammers is doubled.  Also an electronic control is used so that adjacent hammers cannot be fired simultaneously. The hammers are divided into two groups with members of each group alternating on a one for one basis along the hammer bank.  Control circuits are utilized to prevent one of the groups of hammers so defined from firing at the time the other group is being fired.  The result is that the hammers which are fired will all be operating on the same relative dot position in their space in the line of print being formed.  With normal dot band hammers, additional spacing is allowed between dots on the band to avoid the problem of nipping and crashing of the anvil elements on the back of the dot band into extended faces of adjacent print hammers.  This has created a small gap in which no dots can be created.  The present invention also provides a means for automatically selecting large or small dots for printing if the print band has large and small size dot font ele-ments alternated serially on it.  It is only neces-sary to choose firing the hammers of the first group or the second group first in order to select large dots or small dots for printing.
