Title: Electrocatalytic asymmetric dihydroxylation of olefinic compounds
Inventor: GAO YUN
IPC: C25B3/23
Filed: 1993-02-19
Granted: 2005-11-01
Abstract: A process is disclosed in with optically active glycols are produced through an electrolytic asymmetric dihydroxylation (ADH) reaction involving olefins as substrates. The ADH reaction is mediated by a catalytically active amount of osmium tetroxide or osmium-containing precursor in a profit medium in the presence of chiral ligand. Any lower valent osmium species produced in the course of the ADH reaction is regnerated electrolytically either directly in the absence of a secondary oxidant or indirectly in the presence of a secondary oxidant that itself undergoes electrolytic regeneration.

Granted: 1998-08-18
Abstract: A pay per use system  for  the  prevention  of  the unauthorized use  of  computer  software.   An encryption program  encodes  original  software  to  produce  secured software.     The  encoding  is  accomplished  by  using cryptographic techniques.  In order to use the software, a user  must  call  a  telephone  number  to  receive  the cryptographic  keys  necessary  to  decrypt the  secured software.  Thus, users must pay for each use of the secured software.  The system allows software developers to freely distribute the secured software.   Copies of the secured software may be freely made, because payment is based on each use of the software not on each copy of the software.

Abstract: A fish counting method for counting the number of fish by emitting an ultrasonic wave or an electromagnetic wave to a predetermined area where fish pass in a fish farming pool, a river, or the like and receiving reflected waves from fish bodies, wherein, the reflected waves received from a cross section of the predetermined area are periodically stored and an ultrasonic wave fish shade image that shows changes of fish shades is produced, and fish are counted by carrying out an image processing for discriminating the ultrasonic wave fish shade image based on a predetermined fish shade decision rule.  With this arrangement, errors due to muddiness and dusts in water can be reduced and an automatic continuous measuring for a long term can be achieved.

Abstract: L'invention concerne un procatalyseur pour la production de polymères de l'éthylène. Ce procatalyseur comprend un support inorganique, un composé de chlore appliqué sur le support, un composé de magnésium appliqué sur le support, et un composé de titane appliqué sur le support. Le composé de chlore peut être différent ou identique au composé de magnésium et/ou au composé de titane. Le facteur AB exprimant l'équilibre de l'activité du procatalyseur dans des conditions spécifiques de polymérisation est supérieur à 3,2. Ce facteur AB est donné par AB = [(A + A'):2].[log(MFR2': MFR2): (A - A')]. A représente l'activité de polymérisation exprimée en kg de PE par gramme de catalyseur par heure, MFR2 représente l'indice de fluidité en g/min sous une charge de 2,16 kg, conformément à la norme ISO 1133. L'absence de signe "prime" indique une polymérisation effectuée dans des conditions aboutissant à un indice de fluidité bas et la présence du signe "prime" indique une polymérisation effectuée dans des conditions aboutissant à un indice de fluidité haut. Cela signifie que l'activité du catalyseur est relativement indépendante de la présence d'agents de transfert de chaîne.

Abstract: The invention relates to a slip design with substantially longitudinally oriented wickers, which can be used alone or in combination with transversely oriented wickers, to secure a downhole tool, such as a bridge plug or packer, against rotational forces, such as those imparted from a whipstock, as well as longitudinal forces, such as those ultimately delivered by pressure fluctuations from uphole or downhole. The longitudinally oriented wickers are further cammed against the casing since any imparted torque on the packer body contacts a corner or edge of the slip, imparting to it a camming action making it dig further into the casing surface.

Abstract: A method and apparatus is disclosed which spatially enhances stereo signals without sacrificing compatibility with monophonic receivers. In accordance with one embodiment of the present invention, a stereo enhancement system (60b) is implemented using only two op-amps (51, 52) and two capacitors (C1 and C2) and may be switched between a spatial enhancement mode and a bypass mode. In other embodiments, simplified stereo enhancement systems are realized by constructing one of the output channels as the sum of the other output channel and the input channels. In other embodiments, a pseudo-stereo signal is synthesized and spatially enhanced according to stereo speaker crosstalk cancellation principles. In yet other embodiments, the respective spatial enhancements of monophonic signals and stereo signals are integrally combined into a single system capable of blending, in a continuous manner, the enhancement effects of both.

Abstract: A system and method in which the user is provided the option of automatic recall of selected numbers which have been previously called.   The computer based system which  is  controlled  by  operation  of  a  conventional push-button telephone  repeatedly  places  selected  calls and plays a selected prerecorded message whenever a call is  answered.   Processors  provide  the  capability  of recognizing the results of each call as to whether the call has reached a number which is busy or is answered, and also as to whether the call is answered by a person or by an answering machine.   In response to recognition signals,  the  system,  at  the  appropriate  time,  plays a selected  message.   When a  call  has  been  successfully completed  the  called  number  will  be  removed  from  a numbers  queue within  the  system,  and  the  system will record  the  time  and  date of  the completion.   Numbers remaining   in   the   queue  will   be   recalled   until successfully  completed.    The  number  of  unsuccessful recalls,  and the time at which each was made,  is also recorded by the system.   The system is programmable to make calls during selected time periods.  A display panel provides information relating to operation of the system.

Abstract: An ATM transmitter that distributes an ATM transmission process function to plural electronic circuit packages and performs transmission process by forming routes between the plural circuit packages, whereby the route can be flexibly varied while the configuration of a variety of process functions can be managed. The cell distribution section which has plural input and output terminals connected to respective electronic circuit packages forms a route between arbitrary input and output terminals so that receive ATM cells are input and output between respective electronic circuit packages. Process functions are arranged for each electronic circuit package. The function configuration of all the electronic circuit packages is previously set. Thus, a route formation is indicated to the cell distribution section. In other case, input and output terminals for each route are sequentially arranged along the route. The control order of receive ATM cells is previously set. Thus, a receive ATM cell transmission process is performed by the cell distribution section. Moreover, the number of times ATM cells are input and output is arranged for each input and output terminal so that the cell distribution section repeats an input and output operations to the same input and output terminal.
