Abstract: Abstract of the Disclosure Disclosed is a method for filling a cartridge which can be subsequently capped and closed.  This is done by filling to a discrete level and then applying a closure.          A displacement dome is provided at the lower portion of the syringe cartridge closure to first displace a predetermined amount of air or gas and then to displace a minor amount of fluid upon closure to seal the cartridge, and insure zero head space.  The entirety of the process of filling is done in a vented environment, and the closure applied at ambient.          The invention also provides an apparatus which includes a syringe cartridge having its open lower portion closed by a plunger piston.  The upper portion is closed by a syringe cartridge closure having a leur tip cap.  Means are optionally provided interiorly of the tip cap to retain a hollow needle, which is held in position by a leur tip, the latter being vented and provided with a seal for the needle.          The piston plunger at the lower portion of the cartridge can be advanced, desirably by a second plunger, to empty the contents.  Upon resealing, the leur tip cap is applied over the leur tip after a bead is formed on the tip. The tip cap then penetrates the leur tip, or optionally the interior of the hollow needle thus completely reclosing the cartridge and sealing the same for storage until intended for further use.

Abstract: ABSTRACT OF THE DISCLOSURE        A particulate synthetic catalyst material composed of sub-stantially aluminum oxide promoted with 0.5-10 W % total metal and having total pore volume of 0.350-0.500 cc/gm for use in demetallization and hydroconversion processes for metals-containing hydrocarbon feedstocks.  The catalyst material is preferably spherical shaped and provides a narrow differential size range having a particle equivalent diameter ratio range for larger to smaller particles of about 1.2-2.0, and a preferred nominal 12-18 mesh (U.S. Sieve Series) particle size range.  The catalyst can be advantageously used in an ebullated bed reactor in a hydro-demetallization process for hydrocarbon feedstocks containing high metals concentration at reaction conditions of 780-850°F tempera-ture and 1000-3000 psig hydrogen partial pressure.  Use of such synthetic catalyst results in improved reactor fluidization opera-tions and low catalyst loss by attrition and carryover of fines from the reactor, and achieves improved results of 60-70 W % hydro-demetallization and 50-70 V % hydroconcersion of the 975°F+ fraction of the feed material to lower boiling hydrocarbon pro-ducts in a single stage operation.

Abstract: 59-139,499 MATERIAL FOR ELECTRIC CONTACTS      Abstract A material for forming contacts for use in connectors,  switches  and  the like  for electronic appliances.  The material comprises a first metal layer having a conductivity, a second metal layer having a springiness and a plastic layer interposed between these metal layers.  With this arrangement, the two metal layers take charge of the conductivity and the springiness, respectively, so that the contacts according to the invention are small-sized and inexpensive in comparison with prior art contacts made of copper alloys under the same current capacity and contact pressure.   Moreover,  the contacts according to the invention can eliminate disadvantages of the prior art contacts made of two directly contacted metals, such as separation between them due to difference in coefficient of thermal expansion and elongation, deterioration of the  contacts  due  to  diffusion  therebetween,  and disintegration of the contacts due to electrochemical corrosion resulting from difference in electric potential between two metals.

Abstract: Abstract The method for controlling the rate at which a downhole logging tool samples and records a detected condition obtains three samples of the condition at three consecutive sample times and computes a prediction value for the n-th sample from the first three samples.  The method compares the actual n-th sample with the predicted value and records the (n-1)-th sample if the variance between the predicted and actual values is outside a predetermined threshold or difference.  The sample rate is changed if the actual values of the samples remain within the predicted value's prese-lected range for more than a preselected number of samples.          The sample rate interval is also increased if the battery life or memory capacity decrease below predetermined thresholds.  The sample rate interval is decreased to its shortest interval if a pressure change above a predetermined threshold is detected.

Abstract: ABSTRACT OF THE DISCLOSURE        OPTICAL GUIDED WAVE SIGNAL PROCESSOR FOR MATRIX-VECTOR MULTIPLICATION AND FILTERING          An array of fiber optic couplers coupling an input and an output waveguide.  The output waveguide is routed among the couplers of the array such that either backward or foward coupling exists.  With backward coupling, energy coupled into the output waveguide in a coupler of the array is guided back to the preceding coupler for coupling back into the input waveguide.  The backward coupling allows recirculations to occur between couplers to create poles and zeroes in the transfer function of the array which transfer function can be programmed or tailored somewhat to have specific characteristics.  Further, the backward coupling allows the array to be used for matrix-vector multiplication.
