Abstract: Substituted toluenes are brominated in the side chain by reaction with 0.5 to 3.2 mol of bromine per mol of substituted toluene at 100 to 250 DEG C, the reaction optionally being carried out in the presence of a solvent and the hydrogen bromide formed at the same time continuously being removed from the reaction mixture. Depending on the amount of bromine employed, mixtures are obtained in this reaction which contain 90 to 93 % by weight, relative to the total weight of the mixture, of substituted benzal bromide in addition to small amounts of substituted benzyl bromide and substituted benzotribromide, or mixtures which contain 15 to 95 % by weight of substituted benzotribromide in addition to 5 to 85 % by weight of substituted benzal bromide, all relative to the total weight of the mixture, or 40 to 85 % by weight of substituted benzal bromide in addition to 15 to 60 % by weight of benzyl bromide, all relative to the total weight of the mixture. Furthermore, mixtures can be obtained which contain 95 to close to 100 % by weight of substituted benzal bromide in addition to close to 0 to 5 % by weight of substituted benzyl bromide. The substituted benzal bromides obtained or mixtures which chiefly contain such benzal bromides can be used for the preparation of the respective benzaldehydes by alkaline hydrolysis of the benzal bromide group.

Abstract: Une radiation optique de frequence stable est generee en utilisant un modulateur electro-optique pour produire a partir d'une radiation d'un laser de puissance qui possede des fluctuations de frequence inherentes, une bande laterale optique de la radiation qui possede la frequence stable. Un signal de modulation est applique au modulateur (12), le signal etant base sur un signal de difference de frequence qui represente la difference des frequences entre la sortie du laser de puissance (10) et un signal optique obtenu a partir d'une source de reference extremement stable (20). La radiation de reference decrite est la radiation de sortie directe d'un laser de reference stable. Dans un mode de realisation, les impulsions d'un laser TEA CO2 de haute puissance fonctionnant sur un simple mode sont synchronisees avec un amplificateur a bande large a impulsions (22) qui amplifie le signal de difference de frequence pour produire le signal de modulation, et un temporisateur optique (30) dans la trajectoire de sortie du laser de puissance, precedant le modulateur, corrige la temporisation creee par l'amplificateur et par d'autres sources de temporisation. L'invention permet d'obtenir des lasers a impulsions sans gresillements, et des lasers ayant une frequence stable d'impulsion a impulsion. Des systemes ameliores "Doppler Lidar" et d'autres systemes "Lidar" utilisent la sortie stabilisee comme radiation de sonde.

Abstract: Kohlenwasserstoffgemische, die mindestens ein tert.-Olefin enthalten, werden mit einem Alkanol an einem sauren Kationenaustauscher umgesetzt, wobei ein Produktgemisch entsteht, das den entstandenen Alkyl-tert.-alkylether, überschüssiges, nicht umgesetztes Alkanol und die restlichen Kohlenwasserstoffe enthält, die in dem ursprünglichen Kohlenwasserstoffgemisch enthalten waren. Weiterhin enthält dieses Produktgemisch untergeordnete Mengen an nicht umgesetzten tert.-Olefin, wobei dieser Gehalt bei vollständigem Umsatz des tert.-Olefins auf 0 absinken kann. Das überschüssige, nicht umgesetzte Alkanol wird aus dem anfallenden Produktgemisch oder aus einen in der Aufarbeitung anfallenden Teilströmen durch Absorption an einem synthetischen Ionenaustauscher mit Kationen oder Anionen austauschenden Gruppen oder Gemischen solcher Ionenaustauscher als Absorberharz entfernt. Das in die Reaktionszone einzuführende Alkanol wird mindestens teilweise durch Desorption von einem mit diesem Alkanol beladenen Absorberharz mit Hilfe des mindestens ein tert.Olefin enthaltenden Kohlenwasserstoffgemisches entnommen. Zur Alkanol-Absorption und -desorption werden mindestens zwei Absorberharzschichten eingesetzt, die im Taktbetrieb von Absorption auf Desorption und umgekehrt umgeschaltet werden. Das den Veretherungsreaktor verlassende Produktgemisch kann zunachst an einem Absorberharz vom überschüssigen Alkanol befreit werden und danach durch Destillation in den Alkyl-tert.-alkylether und das Restgas getrennt werden. Das den Veretherungsreaktor verlassende Produktgemisch kann jedoch auch zunächst durch Destillation in den Alkyl-tert.-alkylether und in das Restgas getrennt werden, wobei mindestens einer der erhaltenen Teilströme alkanolhaltig ist, und danach kann der oder die alkanolhaltigen Teilströme an einem Absorberharz vom Alkanol getrennt werden.

The data communication system is characterized: in that at least one of the node equipments includes means for generating and transmitting repeatedly for a predetermined period the channel which contains a data transmission bit and a validity bit for the former bit: and in that each of the node equipments linked to the common signal transmission line partly sends out the data through said channel and partly makes the validity indicating bit indicate an invalid state, when the speed of said data is so slower than the predetermined period of said channel that the data to be sent out for the predetermined period are out of time thereby to make it possible to effect the data transmission at an arbitrary speed shorter than said predetermined period. 
     Herein also disclosed is a data communication system in which a plurality of node equipments are jointed by a common transmission loop line and in which the information of multiple channels is repeatedly transmitted for a predetermined period to said transmission loop line so that the channel information may be sent and received between terminal equipments linked to said node equipments. The data communication system is characterized in that an idential pattern for synchronization is inserted into and transmitted by the plural head channels of each period so that the synchronization is effected at each of said node equipments by detecting the synchronizing pattern received by means of a detecting circuit.

Title: Compteur avec sauvegarde non-volatile de son contenu

Filed: 1983-04-12
Abstract: L'invention concerne les compteurs. Une décade de comptage non volatile est décrite. Elle comprend cinq bascules dont les sorties (A, B, C, D, E) définissent un contenu décimal de la décade selon le code de Johnson. Dans ce code, chaque bascule ne change d'état que deux fois par cycle de comptage de 0 à 10. L'état du compteur est sauvegardé à chaque incrémentation dans un circuit de sauvegarde (à transistors MNOS ou à grille flottante) propre à chaque bascule. Toutefois, l'état de chaque bascule n'est sauvegardé que si cette bascule à changé d'état lors de l'incrémentation, ce qui est détecté par un circuit logique (32) de sélection de la commande de sauvegarde (Ca, Cb, Cc, Cd, Ce) de chaque bascule. On économise ainsi, grâce à un circuit combinatoire très simple (32), un grand nombre de cycles d'écriture dans les transisters MNOS ou à grille flottante qui ne peuvent supporter des cycles d'écriture trop nombreux.
