Abstract: Abstract of Disclosure Method and apparatus for determining on board a heaving drilling vessel, the flow rate of drilling fluid flowing from a wellhole and into a telescoping marine riser connect-ing the wellhole with the vessel.  A measuring apparatus is associated with a drilling fluid return conduit of the riser in such a position that the measuring apparatus and the portion of the conduit between the measuring apparatus and the riser are at all times filled with drilling fluid.  The measuring apparatus generates a first signal proportioned to the flow rate of drilling fluid flowing therethrough, measures the drilling fluid level in the riser and generates a second signal proportional to the change in volume of the drilling fluid contained therein above the point at which the conduit intersects the riser.  The telescoping movement of the riser is measured and a third signal is generated proportional to the change in volume of the flow path pro-vided by the riser between the wellhole and said point.  The first, second and third signals are correlated with each other whereby the measured flow rate of the drilling fluid is modified to compensate for the telescoping of the marine riser and the drilling fluid stored in the marine riser above the point the conduit intersects with the marine riser, whereby the true flow rate of the drilling fluid flowing out of the wellhole and into the marine riser is determined onboard the heaving vessel.

Abstract: ABSTRACT OF THE DISCLOSURE Novel electrochemical cells are provided herein.  In such cells, one electrode is an expanded mass of particulate material, means for passing an electrolyte through the expanded electrode and a counterelectrode in direct electrical contact with at least some particles of the expanded electrode, the counterelectrode being electrically conducting but having a contact re-sistance in air between itself and copper test surface of at least 10 times the contact resistance under the same conditions of measurement between the copper test surface and another surface of copper.  An electrolyte is passed through the particulate electrode, possibly for fluidising and/or circulating the particles of the electrode.  Suitable particulate materials include ruthenium oxide, lead oxide nad iron oxide.  Whereas in previous cells of this kind, a diaphragm has been arranged between the particulate electrode and the counterelectrode of the cell, it has been discovered that such a cell can be operated with the counterelectrode actually in contact with particles of the particulate electrode provided the material of the surface of the counterelectrode is suitably chosen.

Abstract: Abstract of the Disclosure An optical switch of the switched directional coupler type is provided with an adjustable cross-over state as well as an adjustable straight-through state, in order to provide reduced crosstalk in the cross-over state, for example, when the switches are used in an optical switching system.  The improved switch is based on asynchronous or phase-mismatched coupling between two parallel optical strip guides driven by electrodes to which the voltage is applied.  In order to use phase-mismatched coupling instead of phase-matched coupling for the cross-over state, in order thereby to obtain electrical adjustability of that state, the driving electrodes are split into two or more sequential sections, thereby defining two sequential coupling sections of the parallel optical strip guides.  The cross-over coupling is then achieved by switching the mismatch conditions so that at the point of partial coupling the "nonoriginating" guide appears to the coupled optical waves to be the "originating" guide.

Abstract: OPTIMAL DRIVER FOR LSI               Abstract of the Disclosure An intermediate driver circuit comprising at least five stages which are cascaded between a signal driver, such as a logic circuit on an LSI chip, and a high capacity load driver, such as a driver for long off chip inter-connection lines, wherein the total delay in the signal source caused by great disparity between the capacitance of the signal driver and the load driver is minimized.          The delay is minimized by use of a cascaded series of n-intermediate drivers where n=lnM, M =  , and where the capacitance of any intermediate stage is  .   Use of these parameters in the design of intermediate stages, each having a capacitance designed in accordance with the foregoing equations has been found to be useful in connection with amplifiers having five or more intermediate stages, and wherein the ratio of capacitance of the load circuit to the capacitance of the driver circuit is greater than about one hundred to one.  The utility of these design parameters in instances where the ratio of capacitance is greater than a thousand to one, and the number of intermediate stages is ten or greater is particularly apparent.

Abstract: DARLINGTON TRANSISTOR  DEVICE            Abstract of the Disclosure In a device of the Darlington type providing a connection of transistors formed on a monolithic substrate there is a collector region of a first conductivity type and a base region of the second conductivity type forming a P-N junction.  The base region contains at least two emitter regions which are simultaneously formed therein with a space between them.  They have the same conductivity type as each other, which is opposite to that of the base region.  The improvement comprises the provision of an obstruction region having the same conductivity as the emitter regions and located in the space between them.  The depth of the obstruction region is larger than that of said emitter regions whereby a narrow path is formed between the collector-base P-N junction and the P-N junction formed between the obstruc-tion region and the base region.  This path functions as a bias resistor connected between the bases of the transistors of sufficiently high resistance value to give the device satisfactory characteristics.

Abstract: -Abstract of the Disclosure Extracellular neuraminidase (NANAase) is produced by the microorganism Arthrobacter sialophilum sp. nov.  The enzyme is included from this microorganism by a variety of glycoproteins.  The preferred enzyme inducer is a hot water extract of edible bird s nest which has been mildly acid-treated.  The microorganisms, after aerobic growth in complete medium of relatively simple composition, are har-vested, washed, salt-shocked, and induced in mineral salts solution which leads to facile enzyme induction.  The produced NANAase is purified by ammonium sulfate fractionation, DEAE cellulose chromatography, gel filtration and ultrafiltration. The enzyme can further be readily crystallized from concen-trated solutions.  Disc gel electrophoresis at both acidic and basic pH's showed a major protein band.  The predominant protein contained NANAase activity.  The NANAase has an apparent mole-cular weight of 87,000 daltons.  The purified enzyme has a pH optimum of 5-6, an apparent Km of 2.08 mg/ml for Collocalia mucoid  and 3.3 x 10-3 M for N-acetylneuraminlactose and is insensitive to Ca++ ions and EDTA.  Linkage specificity studies using N-acetylneuraminlactose and colominic acid indicated that the NANAase hydrolyzes (.alpha., 2-3), (.alpha., 2-6) or (.alpha., 2-8) linkages. The above-identified microorganism produces about 5 mg of NANAase/liter of induction medium and is an excellent source for the preparation of relatively large quantities of homogeneous NANAase.
