Abstract: The invention relates to a chemiluminescent composition, ie one which emits light when its various constituent components are mixed together. 
     The composition consists of a least two separate solutions of at least one oxalate, at least one fluorescent substance, hydrogen peroxide and at least one catalyst, in which those componenets which react together are kept separated. The characteristic of the 9,10-bis(phenylethynyl)anthracene is that the oxalate is a bis(dihalo-acylphenyl)oxalate. This compound is easily and economically produced and is easily soluble in the solvents used, to provide high-intensity light emission for long time periods. The 2,4- or 2,6-acyl substituted phenyloxalate also forms a subject matter of the invention.

Abstract: Die Erfindung betrifft eine Ansteuerschaltung für permanenterregte 5-Phasen-Schrittmotoren mit einer 5-Eckschaltung (Fig. 1) in Reihe verbundene Statorwicklungen (W 1 bis W 5). An die zwischen den einzelnen Statorwicklungen befindlichen Knotenpunkte (2) sind elektronische Schalter zum Anlegen der Versorgungsspannung mit unterschiedlicher Polarität angeschlossen. Mit Hilfe dieser Schalter (S 1 bis S 5) kann zusätzlich zu den beiden aktiven Schaltpositionen zum wechselweisen Anlegen der Versorgungsspannung mit unterschiedlicher Polarität, eine dritte Schaltposition zum Freischalten des jeweiligen Knotenpunktes (2) vorgenommen werden. Dadurch sind nun Ansteuerkonfigurationen möglich, die auch Halbschrittpositionen ergeben. Dies läßt sich erreichen, wenn nach einer Vollschritt-Ansteuerkonfiguration, wo vier Statorwicklungen bestromt und eine kurzgeschlossen ist, anschließend zwei Wicklungen durch Freischalten des dazwischen befindlichen Knotenpunktes in Reihe geschaltet und alle Wicklungen bestromt werden. Es ergibt sich dann der Halbschritt. Weiterhin besteht die Möglichkeit, durch Freischalten jeweils von mindestens zwei Knoten (2) den gleichen Motor auch an doppelter Betriebsspannung gleichwertig zu betrieben.

Abstract: Digital electronic apparatus is described, comprising a number or units which share a common resource, such as a bus. Each unit plugs into a connection slot containing first and second groups of terminals, the slots being arranged in order of priority. When a unit requires to use the shared resource, it applies a signal to all of the first group of terminals in the slot to which it is attached. This signal is then propagated to at least one of the second group of terminals in each lower-priority slot, so as to inhibit a grant signal in all those slots. This enables contention between the units to be resolved in a single inter-unit delay time. The allocation of the terminals to the first and second groups may be fixed, or may be controlled by a slot identity obtained from a further group of terminals.

Abstract: A tubing tester valve comprises a tubular housing assembly (100) having a downwardly closing, spring biased flapper valve (136) disposed therein near the top thereof. A tubular mandrel assembly (102) is disposed within the housing assembly below the flapper valve, and includes a piston section (230), and is secured to the housing assembly with shear pins (270). The tubing tester valve may be permanently opened through the application of annulus pressure from the rig floor to the annulus surrounding the pipe string, which pressure acts on the piston section to move the mandrel assembly upward to rotate the flapper valve to an open position. In order to ensure that the mandrel assembly does not subsequently retract downwardly permitting the flapper valve to reclose, a spring biased locking means (280) is provided to hold the mandrel assembly in its "up" position.

Abstract: In a co-ordinate drive circular scanning pattern tracer, command marks give rise to pulses phase delayed 90° with re­spect to the normal tracing pulses. In a system using a sinu­soidal speed signal and sample and hold circuits to produce co-­ordinate drive signals one sample and hold circuit compares the tracing pulses to the speed signal and the other sample and hold circuit compares 90° delayed tracing pulses to the speed signals. The 90° delayed tracing pulses are compared to the output pulses of the pattern tracer to detect the presence of the pulses produced by command marks. If such command marks a detected and command signal is produced which may be used to control the velocity of the system.

Abstract: A method of facilitating the alphabetical dictionary sorting, by computer, of words based upon characters from a multilingual alphabet, especially the repertoire of characters defined in the new standard alphabet known as ISO 8859/1. This invention uses an encoding scheme (33) to determine the language dependent sort orders for the characters defined in ISO 8859/1. This encoding scheme removes the dependency of sorting on the character set's internal collating representation. This method allows the same sorting software to support many (if not all) of the languages supported by the alphabet. By storing the language dependent sort orders as data files (36), the sorting software is immune to the user's language and hence is highly portable. The number of languages supported is directly proportional to the number of data files available.

Abstract: A well fluid sampling apparatus for sampling fluids from a formation reservoir in a well, comprises a body portion (132,183,196,332) defining a large sampling chamber (194) therein and at least one sampler module (214) disposed in the sampling chamber. The sampler module is adapted for separately entrapping a volume of fluid as the sampling chamber fills. A sliding sampler valve (360) is moved to open a sampler port (434) allowing formation fluid to enter the sampling chamber (194). The sampler module has a metering piston (278) therein which automatically closes the module after a predetermined volume of fluid has entered a sampler module chamber (272) defined in the sampler module. The metering can be accomplished by a chamber (272) filled with a viscous liquid which must be discharged through a small orifice (304) as the piston moves in response to fluid pressure in the sampling chamber. The viscous fluid is discharged into an air chamber (314). Testing gauges may be positioned adjacent each of the sampler modules to measure and record fluid pressure and temperature as desired.
