Granted: 1981-08-25
Abstract: ABSTRACT OF THE DISCLOSURE           Metallo-organic compositions soluble in oils and hydrocarbon solvents, of a high transitional metal content and highly overbased character, are prepared from sources of transitional metals (or of transitional in conjunction with non-transitional metals) reacted with mixed organic acids com-prising at least one monocarboxylic acid and a second acid, either a sulfonic acid or a different molecular weight mono-carboxylic acid.  Formation of the complexes requires the use of excesses of metal over acids, and the use of an oxygen-supplying material such as air, regardless of whether the metal source be a free metal, an oxide or a hydroxide.  Alkoxyalkanols or glycols may be used in addition to the required acids.  These compositions comprise (1) a polynuclear core of a normally in-soluble metal oxide or hydroxide which is crystalline by X-ray and electron diffraction observation, with metal hydroxyl car-boxylate groups (and when present, sulfonate or alkoxyalkanol or glycol groups) ionically and hydrogen bonded to the core element atoms, and additional acid groups having an unbound association with a core and its bonded groups; (2) ultimate particles having structure with minimum average undissociated molecular weight of about 104; and (3) a ratio of total moles of metal to total moles of organic acid moieties being greater than 1 to 1.  The major application for these complexes will be as catalysts for a variety of chemical operations in which prior art metal soaps currently are used.  The use of the complexes results in certain advantages in addition to the high metal con-tent.  The complexes are not only soluble in organic media, but they also exhibit some of the important properties of the metal oxides used in heterogeneous catalysts.  Consequently, they will be useful in bridging the gap between heterogeneous and homo-geneous catalysts by supplying advantages common to each.

Abstract: ABSTRACT OF THE INVENTION         A DC isolation amplifier having improved conductive isolation between its input and output.  The amplifier includes an input section having a modulator and an output section having a demodulator and an oscillator section.  The modulator and demodulator are nonconductively coupled through inductive loops of two closed-loop cores of magnetic material each having windings inductively coupled to the material of their associated core and to the other of the modulator or the demodulator.  Additionally, a unitary closed loop winding couples the two cores so as to minimize the net EMF induced in the turns of the winding by the respective component of the external magnetic field of the turns substantially normal to the respective plane of each turn.          Additionally,  this unitary loop is twisted between the cores to comprise a twisted pair additionally to minimize the effects from external magnetic fields.  In the preferred embodiment, this loop is limited to two turns per core.  However, this number may be increased slightly for certain specific situations.  In preferred embodiments, the cores are housed in magnetic shields, the shields having an opening in one end and the center line of the core is disposed in the plane of the opening of the shield.

Abstract: Canada #3551 A B S T R A C T           A bimodal automatic lens focussing apparatus in-cluding detection and switching means for detecting a loss in a localized focal condition and switching to a search mode wherein the objective lens is scanned between its outer limits to reacquire focus.  Photodiode arrays sense respec-tive light images on either side of the desired focal plane, and the resulting signals are processed to drive the lens to the desired focal plane.  A level discriminator monitors the processed signals.  Upon detection of a loss of the localized focus condition a mode switch is gated to couple a ramp generator to the lens driver.  The lens is scanned between its outer limits until the level discriminator again detects the localized focus condition and the ramp generator is decoupled from the lens driver.

Abstract: ABSTRACT OF THE DISCLOSURE           A fixed functional relationship in either tabular or equation form is established between the growth of various microorganisms in the presence of a few (e.g., one or two) predetermined concentrations of a predetermined antibiotic and the minimum concentration of such antibiotic necessary to at least inhibit the activity of such samples.  The rela-tionships are established for each desired combination of antibiotic and general class of microorganisms and the degree of growth is measured at a predetermined time or level of growth, preferably  before saturation occurs at "growth" or "no growth" extremes.  The minimum concentrations used in deriving these fixed relationships are determined by stan-dard accepted quantitative techniques.  Thereafter, the minimum concentration of the predetermined antibiotic necessary to at least inhibit the activity of any given pathogenic microorganism taken from the same predetermined general class of organisms may be rapidly and accurately determined by (1) measuring the growth of such sampled pathogenic organism after the same predetermined time in the presence of the same few (e.g., one or two) predetermined concentrations of the antibiotic and (2) using the resulting measurements together with the previously established fixed functional relationship to identify the required minimum concentration for that particular combination of micro-organism and antibiotic.  Apparatus for semiautomatically and for automatically carrying out this method are also disclosed.

These water-in-oil emulsions, particularly when derived form charcoal pre-purified MAPTAC momomers, give superior results when they are used to dewater sludges of the type found in municipal sewage and industrial waste treating plants. They are also useful in improving the fine and filler retention during the paper-making process.  Further, they may be used for reducing fluid friction in pipelines and the like.

Abstract: ABSTRACT       The present invention relates to a combination chlorine generation and supply assembly and a method of injecting chlorine into a desired stream of water.  The chlorine generation assembly includes an electrolytic cell having a housing enclosing an anode and a cathode for the generation of gases, including chlorine, hydrogen and means for accommodating the aspiration of the gases from the housing for supply to 2 gas feed system.  The gas feed system includes a housing for receiving water from a body of water such as a swimming pool to be chlorinated and an interior chamber constructed to receive chlorine from the electrolytic cell, to receive water from a major chamber within the feed system, and to accommodate the admixing of the water and the chlorine for injection back into the main body of water.  In the preferred structural arrangement of the gas feed system, the feed system housing includes a top enclosure member and a major body component having a bottom, two sides and two ends.  The admixing chamber for the water and the chlorine is formed at a first end of the housing by a plate attached to that end at a position toward the top of the housing body such that the plate extends downwardly toward the other end of the housing.          The plate terminates above the bottom to form the admixing chamber between it and the first end of the housing and to provide a passageway for water into the admixing chamber.
