Patent EP-0309379-A1 (EP)
Inventor: SANDSTROM PAUL HARRY
IPC: C08K5/17
Filed: 1988-09-07
Abstract: It is often desirable to utilize accelerators in the sulfur vulcanization of unsaturated rubbers. In many cases a primary accelerator is used in combination with another accelerator, called a secondary accelerator or activator, which further increases the rate of vulcanization. It has been determined that compounds having the structural formula:
     wherein x is 2 or 3, wherein n is an integer from 1 to 100, and wherein A represents an alkylene group containing from 1 to 20 carbons atoms, act as secondary accelerators in the vulcanization of unsaturated rubbers. For example, it has been determined that 4,7-diaza-decane-1,10-diamine is a particularly desirable secondary accelerator.

Abstract: A method for the enrichment of carbon 13 by use of multistage laser irradiation. A mixture of CHClF₂ and Br₂ is used as starting material. The mixture is irradiated with laser rays emitted from a carbon dioxide gas laser to obtain CBr₂F₂ enriched with carbon 13. This CBr₂F₂ enriched with carbon 13 is once more irradiated with laser rays emitted from a carbon dioxide gas laser to produce C₂Br₂F₄ which is further enriched with carbon 13. Alternatively, the product CBr₂F₂ of the first laser irradiation is once more irradiated together with O₂ to produce COF₂ which is further enriched with carbon 13.

Abstract: A circuit for automatically matching the gain and offset of a time-shifted digitizing channel in a data acquisition circuit which includes a reference digitizing channel, having a fixed voltage reference, and at least one time-shifted digitizing channel having components that are adjustable for gain and offset. Feedback is provided by examining the dynamic range and average value of a known input signal which is digitized, sent through the time-shifted digitizing channel and stored in memory. A microprocessor reads the stored data and, by separately varying the gain and offset parameters, computes optimal values for each parameter. Digital-to-analog converters (DAC's) allow the microprocessor to communicate with one fixed-gain variable-offset amplifier in the front end and with one fixed-gain variable-offset amplifier and one analog-to-digital converter (ADC) in each time-shifted digitizing channel. By controlling the offset of the amplifiers and the reference level of the ADC, precise matching of the gain and offset of the time-shifted digitizing channel with the gain and offset of the reference digitizing channel may be performed easily and inexpensively. The circuit may be extended to an arbitrary number of additional time-shifted digitizing channels and provides a comparatively simple, inexpensive way to automatically match the gain and offset of each time-shifted digitizing channel.

Abstract: In order to take a practically unlimited number of fluid samples, in particular from a well in production, a sonde is used including as many modular sampling devices (10) as there are samples to be taken. These devices (10) are disposed end-to-end and they are actuated in succession by a central control rod (66) driven back-and-forth by an actuator device situated at the top end of the sonde. A bottom end piece puts the bottom sampling device into a ready position in which it is ready to be actuated by raising the rod (66). By taking a sample in this way, the bottom sampling device also serves to put the adjacent sampling device into its ready position, and so on all the way up to the topmost sampling device.

Abstract: La vitesse de l'entraînement du disque d'un lecteur de CD est régulée à l'aide d'un circuit de régulation de phase qui est réglé manuellement au moment de la fabrication. Afin d'éviter le réglage manuel fastidieux au moment de la fabrication ainsi que les fluctuations de vitesse dues au viellissement des composants, entraînant une détérioration de la reproduction du son, le réglage peut s'effectuer automatiquement. A cette fin, on sépare le régulateur (R) du circuit de régulation de phase de l'oscillateur commandé par tension (VCO). La sortie de l'oscillateur commandé par tension (VCO) est connectée à la première entrée de l'indicateur de phase (P2), la fréquence de référence (BF) étant dirigée vers la seconde entrée dudit indicateur de phase. Un microprocesseur (MP), dont l'entrée (E) est connectée à la sortie de l'indicateur de phase (P2) et dont la sortie (A1) est connectée à l'entrée de l'oscillateur commandé par tension (VCO), modifie la tension à sa sortie (A1) jusqu'à ce que la fréquence à la sortie de l'oscillateur commandé par tension (VCO) corresponde à la fréquence de référence (BF). Le microprocesseur (MP) conserve ladite tension. Le régulateur (R) est ensuite à nouveau relié à l'oscillateur commandé par tension (VCO). Le circuit de régulation de phase est maintenant réglé et opérationnel. Pour un lecteur de CD, le réglage peut par exemple se faire chaque fois que l'on branche l'appareil ou que l'on met un disque ou pendant les pauses séparant deux plages de musique. Ledit circuit de régulation de phase convient particulièrement pour un lecteur de CD.
