Abstract: A process for increasing the direct esterification reaction rate between a diacid and 1,4-butanediol and for directly esterifying greater than 95% of the acid ends of the diacid by mixing in any order the diacid, the 1,4-butanediol and a catalyst compound selected from organo-titanium, organo-tin, and organo-zirconium compounds, to form a reaction mixture wherein the ratio of diol:diacid is at least 2:1 and then reacting the reaction mixture at an average temperature ranging between 190.degree. C. to 200.degree. C. for a period of time no longer than sixty minutes. The same process may be followed substituting ethylene glycol for 1,4-butanediol, provided the catalyst compound is added neat, further provided that the average reaction temperature ranges from 190.degree. C. to 200.degree. C., and also provided that the reaction mixture be reacted for a period of time no longer than seventy minutes.

Abstract: Permeability of structures consisting essentially of dispersions of barrier resins in permeable structural resins can be predicted by the application of near infrared spectroscopy, within the wavelength range of 600-2500 nm, especially 1100-2500 nm. The method requires establishing a correlation between base permeabilities of samples of a Training set and their near infrared spectra, developing from that correlation a predictive equation, verifying the accuracy of the predictive equation on samples of a Validation set, and applying the predictive equation to the determination of the permeabilities of unknown samples.

Abstract: A method is provided for inhibiting loss of cognitive function, including memory, which may or may not be associated with Alzhemier's disease, in a mammalian species by administering an ACE inhibitor, which is a phosphonate substituted amino or imino acid or salt, such as SQ 29,852 over a prolonged period of treatment.

Abstract: Substituted pyrroles, pyrazoles and traizoles such as ##STR1## and their pharmaceutically suitable salts are useful as antihypertensive agents and for treatment of congestive heart failure.

Abstract: A silencer having multiple integrated channels arranged in a labyrinth configuration is provided. The channels have one open end and one closed end with the open end in communication with a common zone which is connected to a flow duct. The channels are tuned to provide a selected resonance frequency.

Abstract: An apparatus for on-line determination and control of the Flow Behavior Index of a molten polymer stream are disclosed along with methods for using the Index as a means for monitoring and controlling polymer quality. In particular, the Index may be used to monitor and control on-line the levels of branching in the polymer and the polymer's molecular weight distribution.

Abstract: A low insertion force type connector is provided which comprises an elongated housing made of an insulating material and having an elongated cavity in a longitudinal direction. A plurality of contacts are located at predetermined intervals along the length of the elongated cavity and are adapted to contact an edge portion of the printed circuit board. A pair of latches are located at opposite ends of the housing providing a spacing defined therebetween over the cavity. Each contact comprises first contact means having a first contact portion for contacting one surface of the printed circuit board and second contact means having a second contact portion for contacting the other surface of the printed circuit board, and a pin portion for supporting the first and second contact means.

Abstract: A system for delivering a fluid from a puncture in a pressurized vessel and particularly for delivering an entry retardant into or adjacent a secure space.

Abstract: Copolyamide desalination membranes formed by interfacial polymerization on a microporous support are disclosed. The copolyamide is formed by copolymerization of m-phenylene diamine with cyclohexane-1,3,5-tricarbonyl chloride and any of isophthaloyl chloride, terephthaloyl chloride, or cyclohexane dicarbonyl chlorides wherein the average functionality of the acyl chlorides is from 2.20 to 2.40.

Abstract: An anti-snoring pillow which reduces the snoring by the user when sleeping by positioning the head of the user such that the degree of blockage in the user's breathing passageway is reduced. The anti-snoring pillow includes a base member which is preferably inclined and has a curved front edge which is lower in height than the rear edge. The upper surface of the base member adjacent the front edge has an elongated bolster secured thereto, which bolster is curved along its length to conform to the curved shape of the front edge of the base member. The bolster also includes a curved peripheral cross-sectional area for comfortable support of a user's neck. The bolster and the base member, and the choice of materials therefor act in conjunction to ensure comfort and also the positioning of a user's head so as to decrease the blockage of the user's breathing passageway when the user is in a back or in a side sleeping position.

Abstract: The image dot gain that normally occurs in a printing press is controllably simulated as a separate step in the process of producing accurate color proofs. The simulation is attained by placing a diffuser plate between a high-intensity light source and a color-separated image master along with its corresponding image receptor. By varying the position of the diffuser plate the percentage of image dot gain is accurately controlled as an independent variable without the need to alter the exposure time.
