Abstract: ABSTRACT OF THE DISCLOSURE             The invention relates to a filter tube and a method for making the filter tube.  The filter tube consists of a plurality of randomly disposed interrelated inorganic fibers having a diameter of from about 0.001 to 10 microns.  The tube forms a semirigid, self-supporting, porous, filter tube of desired filtering porosity and efficiency, and the fibers of the filter are bonded at the junction of the fiber crossover points with a bonding amount of a substantially nonhydroscopic pyrolyzed quaternary ammonium silicate as a binding agent.  The filter tube of the invention is character-ized by a high collapse strength and substantially nondusting properties during handling.  The method for making the tube con-sists of impregnating a filter tube composed of interrelated, non-woven negatively charged inorganic glass fibers, having a diameter from about 0.001 to 10 micorns, with a liquid dispersion of positively charged particles of a nitrogen substitute silicate compound.  The impregnated filter tube is then heated to a tempera-ture of about 800 to 1100°F to provide an inorganic pyrolyzed silica binder, thereby forming a self-supporting porous filter tube subject tot use at high temperature.

Abstract: PROCESS FOR IMPARTING ANTISTATIC PROPERTIES TO PLASTICS      ABSTRACT OF THE DISCLOSURE:    Antistatic properties are imparted to plastics by blending a pulverulent plastics material and, if desired further addends, with conductive carbon black and making the resulting blend into a moulding composition. The pla-stics are more particularly blended with 4 to 12 weight % of conductive carbon black having a water absorption stiffness (AS-number) of 15 to 35, a specific electric resistance of 10-1 up to 10-3 ohms . cm under a moulding pressure of 100 to 180 atmospheres absolute, a bulk den-sity of 100 to 180 g/liter, a BET-surface area of 100 to 1000 m2/g. The carbon black is made by a process wherein an aqueous suspension of carbon black having an AS-number higher than 15 is intimately blended at temperatures with-in the range 5 and 120°C, under pressures within the range 1 and 20 atmospheres absolute, in liquid phase at a pH-value of 7 to 10, and for a period of 1 to 20 minu-tes, with vaporizable liquid aliphatic or cycloaliphatic hydrocarbons, the carbon black is separated from liquid matter, then heated and thereby freed from hydrocarbons and water, and finally annealed for 20 to 30 minutes at 200°C up to 2200°C. The aqueous suspension is prepared by subjecting hydrocarbons, which are liquid at room temperature, to thermal conversion at 1200 to 2000°C, under pressureswithin the range 1 and 80 atmospheres absolute, and in the presence of oxygen or an oxygen-containing gas, and water scrubbing the resulting carbon black-containing reaction gas.

Abstract: 6/24/?5 sam        OPTICAL SUBSTRATE WITHOUT DISTORTING THE UNIFORM DIRECTION OF                            POLARIZATION     ABSTRACT OF THE DISCLOSURE           A stretching frame and vacuum former having an identical geometric shape with the vacuum former being proportionally reduced in peripheral dimensions, permits a stretched molecularly-oriented, light-polarizing, organic film having a uniform direction of polarization to be bonded to a substrate without distorting the direction of polarization.  The method is practiced by supporting the molecularly-oriented, light-polarizing, organic film in contact with the edge of the vacuum former with the vacuum former being located substantially equidistant from the stretching frame and then a vacuum is applied to the chamber of the vacuum former to draw the film down onto the optical element.  By utilizing a stretching frame and vacuum former having identical geometry, the uniform direction of polarization is not distorted by uneven stretching of the organic film as it is drawn down into contact with the glass element by the reduced pressure.

Title: Apparatus for the continuous purification of exhaust gas containing solvent vapours

Abstract: APPARATUS FOR THE CONTINUOUS PURIFICATION OF     EXHAUST GAS CONTAINING SOLVENT VAPOURS     ABSTRACT OF THE DISCLOSURE           The invention is an apparatus for purifying an exhaust gas containing solvent vapours by bringing the exhaust gas and adsorbent particles into continuous mutual contact to adsorb the solvent vapours onto the adsorbent particles.  The adsorbent particles containing the solvent vapours are subsequently regenerated by contact with an incondensible inert gas.  The solvent vapour mixes with the inert gas and is removed from the regenerating section of the apparatus, and most of the vapour is removed from the gas by condensation or the like. The remaining solvent vapour is removed from the regenerating gas by contact with the particles leaving the adsorption section of the apparatus, and then the regenerating gas can be recycled to the regenerating section.  The advantage of the apparatus is that it enables an incondensible inert gas to be used as the regenerating gas, instead of the conventional steam or the like, by providing for almost complete removal of solvent vapours from the inert gas after regeneration of the particles so that the gas may be continuously reused for the regeneration process.

Abstract: BEHIND CASING FLUID FLOW DETECTION IN PRODUCING WELLS USING GAS LIFT (D#74,517-3-F) Methods are provided for locating and measuring the linear flow velocity and volume flow rate of undesired water production behind casing in a producing well operating on gas lift while the well remains in a producing configuration.  A well logging tool sized and adapted for passing through production tubing is lowered through the tubing string into the producing zone.  The tool contains a source of 14 MEV neutrons and two longitudinally spaced gamma ray detectors.  The detector may be placed alternately above or below the neutron source on the tool while maintaining the same source to detector spacing.  With the well on production under gas lift the earth formations behind the casing are irradiated with 14 MEV neutrons, either continuously or in bursts, to activate elemental oxygen nuclei comprising the molecular structure of the undesired water flow.  The decay of unstable isotope nitrogen 16 produced thereby is detected by the detection of its characteristic gamma rays at the dual spaced detectors.  These measurements may then be interpreted in terms of the linear flow rate and volume flow rate of the undesired water flow. I

Abstract: ABSTRACT     An electrical connector for terminating a very fine magnet wire comprising a three sided contact forming three sides of trapezium.  The centre side forms an acute angle with the second side which is serrated and an obtuse angle with the third side. The connector further comprises a housing having a cavity therein for receiving and retaining the contact. The cavity contains a stopping means against which the junction of the first and centre contact sides abut as the contact is inserted into said housing. However, the third contact side continues further into the cavity to cause the acute and obtuse angles to become right angles, thereby pushing the serrated second contact side in a direction normal to the insertion force and against a given wall of the housing and across which the magnet wire has been positioned.

Abstract: OPTICAL POSITION SENSOR          Abstract of the Disclosure A transducer for converting position displacement into a digital output signal correlated to the current placement state, An opaque vane is operably movable transversely in a radiation path between a radiation source and two juxtaposed radiation sensitive diodes.  Discrete signals, emitted by each of the diodes in relation to the amount of their respective surface areas exposed to radiation, are converted by logic and a dual slope integrating analog-to-digital converter to a useful digi-tal output signal.  In one embodiment, both diodes are subject to having exposed radiation interrupted by the vane.  Logic sup-plies the difference of the diode signals to the converter as its measured input while a sum signal is supplied thereto as its reference input.  The ratio of input signals is then emitted by the converter as an output signal indicative of the current placement state.  In another embodiment, only one diode is sub-ject to having radiation interrupted by the vane and its signal comprises the measured input to the converter while the other diode signal comprises the reference input.
