Abstract: Circuit comparateur de fréquence et de phase permettant de déterminer la différence de fréquence entre un signal de référence de fréquence connue et un signal variable de fréquence inconnue. Le circuit contrôle les deux signaux et détecte les déphasages se produisant entre les deux signaux. En particulier, ce circuit détecte les déphasages de 180o et de 360o et enregistre une indication de glissement complet à chaque déphasage de 360o. Ces déphasages indiquent qu'à un instant quelconque pendant la transmission, les deux signaux étaient déphasés et n'avaient pas exactement la même fréquence. Le circuit fournit en outre une indication du sens de glissement à chaque déphasage de 180o. Ces indications du sens de glissement sont produites à la suite d'un déphasage de 360o ou glissement complet et permettent de déterminer les fréquences relatives des deux signaux en indiquant si la fréquence du signal variable est supérieure ou inférieure à celle du signal de référence pendant la durée du glissement complet. Il est ainsi possible d'exécuter les réglages nécessaires pour accorder les deux fréquences.

Abstract: A digitizing system of the type including a tablet, a stylus and associated electronics which is constructed to correct for tilt errors when the stylus axis is tilted relative to the tablet is disclosed. The tablet includes a housing having a rectangular coordinate grid of electrical conductors. The stylus includes an elongated tubular member having a tip at one end, a first coil which is located at a first axial distance from the tip and a second coil which is located at a second axial distance from the tip, the second distance being different from the first distance. A voltage signal is applied to each coil sequentially. The signal applied to each coil induces a voltage in each conductor in the grid. The induced voltages are processed to produce a first and a second data signal, the first data signal corresponding to the position of the first coil relative to the grid and the second data signal corresponding to the position of the second coil relative to the grid, with the difference in the two data signals, if any, being caused by tilt of the stylus. The two data signals are then processed to produce a third data signal corresponding to the position of the tip of the stylus relative to the grid of conductive elements.

Abstract: An improvement in known processes for preparing substituted carboxylic acids useful as acylating agents which comprise reacting (A) at least one aliphatic polymer of one or more lower olefins with (B) an acid reactant selected from the group consisting of fumaric acid, itaconic acid, maleic acid, and the corresponding anhydrides, lower alkyl esters, acyl chlorides and acyl bromides, in the presence of chlorine can be improved by the steps of (i) reacting at a temperature of about 100<o>-200<o>C, a mixture of (A) and (B) in the presence of about 0.05 to 0.15 equivalent of chlorine per equivalent of (A) until of the chlorine has reacted to provide a first intermediate product, (ii) continuing the reaction in the absence of chlorine at a temperature of from about 180<o>-250<o>C until a conversion of 0.4 to 1.1 equivalents of (B) per equivalent of (A) is attained to provide a second intermediate product, and (iii) reacting said second intermediate with about 0.2 to 1.5 equivalents of chlorine per equivalent of (A) used in step (i) at a temperature of about 180<o>-225<o>C. The carboxylic acids produced by this improved process can be used, per se, in lubricants and fuels and as acylating agents in reactions with amines, alcohols, reactive metals or reactive metal compounds to form derivative products which are useful, for example, as additives for lubricants and normally liquid fuels.
