Patent EP-0044510-A1 (EP)
Inventor: FOX DANIEL WAYNE
IPC: C07C69/83
Filed: 1981-07-14
Abstract: Diaryl esters of aromatic dicarboxylic acids are prepared by directly reacting aromatic dicarboxylic acids with a large molar excess of an aromatic monohydroxy compound, ranging from about 15-17 moles of the aromatic monohydroxy compound which is used as a solvent, reactant and as a carrier to remove water formed during the reaction, the reaction being carried out by heating the reagents at an elevated temperature in the presence of stannous oxide (SnO) as a catalyst at about 275°C. to about 300'C. and removing water formed during the reaction and a major proportion of the aromatic monohydroxy compound from the reaction mixture. The process is especially applicable to the preparation of diaryl esters of isophthalic and terephthalic acid, for example diphenyl isophthalate and diphenyl terephthalate by reacting the acids with an aromatic monohydroxy compound, for example, phenol, giving yields of the diesters of 90-95% plus a 5-10% yield of the corresponding monoaryl ester, or half ester. This mixture can then be reacted with a diaryl carbonate, for example, diphenyl carbonate, to convert the half ester into the diester to give a total yield of diester of about 99.9%.

Abstract: A computer-controlled system is disclosed for dispensing selected packages from a vending machine. The system includes an ejector mechanism (10) adapted to travel rectilinearly intermediate a pair of oppositely-mounted storage banks (12, 14), each bank consisting of a plurality of vertically-oriented adjacent compartments (12a, 14a) in which distinct packages are stacked. The ejector mechanism (10) includes a carriage (20) mounted on a helical screw (22) rotatably driven by a travel motor (30). An ejector lever (34) pivotally connected to the carriage (20) is mounted upon an actuator bar (26) rotatably driven by a pivot member (32) for independently actuating one of a pair of overlapping ejector arms (36a, 36b) according to the directional rotation of the pivot motor (32). Each ejection arm (36a, 36b) is pivotally connected to the carriage (20) and configured to discharge a single package from beneath a stack when actuated. A microprocessor (33) controls the rotational drive of the motors and is provided feedback signals indicative of carriage location and package availability by sensors (42, 45) attached to the carriage (20).

Title: Optical transducer means
Inventor: MCMAHON DONALD HOWLAND
IPC: G01D5/30
Filed: 1981-03-23
Abstract: An opto-electronic transducer is provided for converting small displacements into optical intensity or phase variations which may then be converted into varying electric currents. A first optical fibre guide (6) is disposed with its end face facing, across a gap (22), an end face of a second optical fibre guide (10). The guides (6,10) are attached to respective link rods (9, 11) enabling relative displacement of the ends of the guides (6,10) in proportion to the parameter (such as pressure) to be measured. The sensitivity of the transducer is enhanced through the use of large core, large numerical aperture, multimode optical fibres. The opposed faces of the cooperating fibre guides (6,10) are equipped with or are used to illuminate regular arrays of equally spaced opaque, absorptive, or reflective grating systems providing intensity or phase modulation of the propagating light energy in proportion to wave guide deflection.

Abstract: En vue d'eviter des variations dans la qualite des melanges ou des liaisons au cours du temps, on ajoute au moins un composant distinct seulement au cours de l'utilisation. On enferme le composant dans un reservoir (40) et on le stocke dans la partie en mouvement d'une soupape de dosage (20). A cet effet, un manchon (35) est fixe a la base de la soupape (4), qui possede un epaulement (36) pour soutenir le reservoir (40) et qui presente une embouchure (32). En comprimant la soupape (20) en direction du reservoir (40), celui-ci est detruit ou ouvert; le composant peut ainsi etre melange au composant se trouvant dans le reservoir sous pression. L'action de la soupape resulte d'abord de la fixation d'une fermeture amovible, qui est enlevee apres le melange des composants, apres quoi le melange est utilisable. Avec cette disposition, une conservation longue du contenu du reservoir est possible; il peut etre utilise egalement de maniere simple au moyen du reservoir sous pression.
