Abstract: IMPROVED ARRANGEMENT FOR PROTECTING          A ROTARY DEVICE FROM IMPACT THRUST FORCES     ABSTRACT OF THE DISCLOSURE      A means is described for restraining axial movement of an output shaft of a prime mover which protects the prime mover from undesired axial impact loads applied thereto. The protective means comprises a first body mounted to a rotating output shaft for motion in an axial direction upon the application of a thrust force to the body and a second body which is stationary relative to the output shaft. Means bias the bodies apart and enables mutual engagement there-between which restricts movement between the bodies in an axial direction when an impact force is applied to the first body.

Abstract: MD.md SMOKE DETECTOR         Abstract of the Disclosure An improved smoke detector having a faster response time, greater immunity to ambient energy, and lower maintenance is disclosed.  The smoke detector uses modulation techniques to differentiate within a smoke detection chamber between am-bient energy and energy from a transmitting source.  A delayed automatic gain control is provided to reduce the effects of slow change of parameters in the detector itself and to provide greater discrimination between smoke which should cause an alarm and smoke resulting from, for example, tobacco. The disclosed improved smoke detector further provides for increased signal-to-noise ratios thus providing for more accurate and precise measurements.

Abstract: ABSTRACT OF THE DISCLOSURE         The degree of fullness of a mill driven by an electric motor is measured by, firstly, measuring the variation of the power input of the mill and, secondly, determining the degree of fullness on the basis of the degree of variation of said power input, whereby use is made of test or calibration measurements performed, previously with different degrees of fullness.  Perferably a current or voltage signal descriptive of the power input is created and then a signal representing the degree of full-ness is generated as proportional to the amplitude of said voltage or current signal.

Abstract: POLYESTER TEXTILE MATERIAL  HAVING IMPROVED OPACITY     Abstract of the Disclosure A polyester fiber textile material made by the application of titanium dioxide pigment thereto is provided.  According to the process by which the textile material is made, the titanium dioxide pigment having a particle size of at least about 0.18 micron is exhausted from a dispersion of same onto the textile material at a pH below approximately 7.5.  Subsequent heat set-ting of the polyester textile material improves retention of the titanium dioxide pigment.     It has long been known that textile materials, that is spun yarns, exturded filaments, woven fabrics, knitted fabrics, non-woven materials and the like can be rendered more opaque by the addition of various metal oxides, such as titanium dioxide thereto.          By adding opacity to a sheer textile material, the covering power of the material is greatly improved, without the extra weight and cost that would be present for a heavier, tightly formed substrate.          Likewise, in so adding opacity to the textile material it is quite desirable, if not imperative, to avoid changing the handle characteristics to a point where the material becomes unsuited for garment use, for example, and the improved opacity charac-teristic should be retained after repeated launderings or dry cleanings.

Abstract: ABSTRACT      DECATIONISATION OF AQUEOUS SUGAR SOLUTIONS      Aqueous sugar solutions are agitated in a batch process with strong cation exchange resin, optionally mixed with anion exchange resin, or with a mixture of weak acid cation exchange resin in the hydrogen form and anion exchange resin, under closely defined time and temperature conditions to effect decationisation or deionisation without the degree of cooling and dilution required in conventional fixed bed processes.   In the presence of strong acid cation exchange resin the temperature is 20 to 40°C and the contact time between sugar and resin is at most 20 minutes, unacceptable levels of inversion thereby being avoided.   When weak acid resin is used as the cation exchange resin the temperature is 20 to 90°C and the contact time is at most 90 minutes. When mixed anion and cation exchange resins are used colour bodies are removed from the sugar solution.

Abstract: ABSTRACT         Portland and other hydraulic cements are produced by introducing nodular, pulverulent, or molten feed materials, properly proportioned, into a melt that is contained within an electric furnace.  The furnace may be arc, induction, resistance or other type using electric current as the source of energy. This current not only heats the melt, but further serves to produce turbulence which mixes the feed materials within the melt so that those feed materials chemically combine within the melt, providing the melt with the desired chemical constituency.  The size, form of electrical energy input, and other design features of the furnace are related to required feed rate and the material melting rate.  The melt is thereupon withdrawn and cooled to solidify it into a substance that has the chemical constituency and properties of the desired hydraulic cement.

Abstract: ABSTRACT OF THE DISCLOSURE      For use in a suspended ceiling system a pair of beams joinable end to end in aligned relation, each of the beams having a vertical web and lower flange at right angles thereto.  The beams have identically formed end portions each terminating in a horizontal tongue integral with the web.  Each web has formed therein a window having an inwardly spaced "locking" edge and having a vertical dimension just slightly greater than the height of the tongue. Each of the tongues is notched and bent along its upper and lower edges to form a pair of integral hooks.  The tongues are sufficiently straight with respect to the plane of the web so that when a tongue is received in the window of the companion beam it bears with resilient lateral force against the far edge of the window, insuring that the hooks "catch" behind the locking edge to a desired depth.  The tongues may be withdrawn from the windows by a force applied at an angle having a lateral component in a direction to bendingly stress the tongues for disengagement of the hooks.  The far edge of each window is formed with an integral tang bent convergently from the plane of the web to engage the tip of an inserted tongue to guide the same into the window, the tang optionally serving as a positive lock.

Abstract: ABSTRACT The object of the invention 3 to provide an improved method for removing caffeine from aqueous solutions such as coffee and tea extracts. Decaffeination with liquid, water-immiscible, caffeine-specific solvents having relatively low partition coefficients has in the past required very high solvent-to-extract ratios and has resulted in the loss of an undesirably high level of non-caffeine soluble solids. The process disclosed herein decaffeinates an aqueous caffeine feed solution by contacting it with a multi-phase extractant which comprises a continuous phase of a liquid, water-immiscible, caffeine specific solvent and discontinuous aqueous phase dispersed therein. The caffeine is selectively extracted from the aqueous feed solution, leaving the solubles necessary for a good tasting beverage due to the high combined selectivity of the extractant phases. Very low solvent-to-extract ratios are possible because the multi-phase extractant has a much improved partition coefficient as compared to the water-immiscible solvent.

Abstract: ABSTRACT   A flame spraying device including a rocket accelerator wherein a low velocity flame is produced into which a coating material is introduced.          At least one rocket accelerator producing a high velocity stream of combustion product gases is positioned relative to the low velocity flame so that the coating material carried thereby is accelerated toward the substrate to be coated.  By positioning the rocket relative to the low velocity flame, the dwell time in the low velocity flame can be optimized to produce the best coating of a substrate.  The coating quality is also enhanced by the fact that the coating material does not oxidize or cool significantly while in the high velocity stream and by the fact that the coating material strikes the substrate at high speed thereby resulting in high density coating.                                 .
