Title: Multi-bushing single-phase electric distribution transformer for feeder phase current balancing
Inventor: LLANO LUIS F
IPC: H02J3/26
Filed: 1993-01-04
Abstract: MULTI-BUSHING SINGLE-PHASE ELECTRIC DISTRIBUTION TRANSFORMER    FOR FEEDER PHASE CURRENT BALANCING            Abstract In three-phase electric power distribution systems, kilowatt-hour conductor losses can be reduced by keeping the current flows in all three-phases as equal to each other as possible.          A secondary benefit of phase balancing is an improved voltage regulation.          At present, phase balancing can be achieved by taking the phase-current measurements, detecting a feeder with a significant current unbalance,identifying a single-phase transformer connected to the highest loaded phase, and then manually reconnecting it to the lowest  loaded  phase.  The  operation  involves  time  consuming activities  in  engineering,  and  the  deployment  of  personnel, equipment and resources for its execution, plus loss of revenue and/or inconveniences  caused by an outage of  several  minutes duration.     In this invention, a single-phase transformer is provided with: three high-voltage bushings, and an internal high voltage side three-position load-break switch. All the necessary connections are already in place, and through the operation of the switch  the transformer load is transferred from the highest loaded phase to the lowest loaded phase; thereby tending to an equilibrium of circuit phase currents and therefore reducing the system losses.          The invention   makes  the phase-balancing process  fast,  easy, convenient, safe, and economical.

Filed: 1993-04-06
Abstract: Abstract of the Disclosure Apparatus  for  detecting  commercial  variations  in transparent containers such as glass bottles that comprises a light source for directing diffused light energy through a container under inspection. A light sensing camera is positioned to receive an image of the light source transmitted through the container sidewall. A light control film is positioned adjacent to the light source between the light source and the container, and comprises a plurality of parallel slats spaced from each other so as to limit the angle from which the image of the light source can be viewed at the camera.  Commercial variations are detected as a function of variations in light intensity received at the camera.  In the preferred embodiment of the invention, first and second arrays of spaced parallel slats are positioned adjacent to the light source, with the slats of the first array being at an angle to the slats of the second array so as to project a moiré fringe pattern through the container onto the camera.

Abstract: ABSTRACT.            PROCESSED ATLANTIC SEAWATER.            WATER has been called the most "ESSENTIAL NUTRIENT".          Since creation, the amount of water on this Planet has not changed. However,  our  supplies  of  clean  usable  water  is  limited,and Canadians and indeed all the peoples of the World, must learn to use Water more wisely!!          The Product, PROCESSED NORTH ATLANTIC SEAWATER, has an average Salinity of 3.5% All the elements known to man are dissolved in Sea Water. The  main substances are:- Chlorine, Calcium, Sodium, Sulphate, Magnesium and Potassium. Sodium Chlorine  accounts for about  85%  of  the  total.  Other  dissolved  solids  present   in significant amounts include Magnesium Chlorine, Magnesium Sulphate, Potassium Sulphate, Calcium Carbonate and Magnesium Bromide.          The therapeutic capabilities and advantages of SEAWATER have been known for many centuries. It has been, and is used as an eyewash, mouthwash, throat gargle, skin toner and wound antiseptic. One prime Worldwide example of these qualities is the DEAD SEA of the Nation of Israel.  For more than 4000 years,  visitors seeking rejuvenation and revitalization have sought the near magical cures and unusual health-giving qualities of the Dead Sea!! So named for it's extraordinarily high levels of salt and minerals, it has the distinction of being the saltiest body of water in the World!! The waters are laden with minerals; in fact they have 50 times more concentrated bromine and 15 times more Magnesium than the Atlantic Ocean!! Bromine relaxes the nervous system and magnesium tones and refreshes the skin. Seawater is soothing to body tissues and is "NATURE'S WAY" to clean and cure!! It is so basic that it goes back to the beginning of time, and MAN as well as all other life is supposed to have come from the sea!!
Patent CA-2094284-A1 (CA)
Inventor: SCHUCHMAN LEONARD
IPC: H04B1/713
Filed: 1991-10-17
Abstract: A digital audio broadcasting system that is capable of providing a large number of high quality stereophonic channels (stereo channels 1 to 33) to mobile receivers in an environment with severe multipath delay (80-I, 80-N) and fading. Intersymbol interference degradations caused by multipath delay (80-I; 80-N) are mitigated via an adaptive equalizer (21) in the receiver. The use of a dynamic single channel per carrier system preserves the simplicity inherent in the single channel per carrier assignment while it incorporates the ability to address frequency-selective fading by providing substantial frequency diversity. Frequency di-versity is achieved via a slow frequency hop implementation in which the assignment of a number of stereo channels to an equal number of carrier frequencies is changed periodically. In this manner, each of many independent stereo channels (stereo chan-nels 1 to 33) achieve the frequency diversity associated with a wide bandwidth by hopping among an equal number of carriers that fully occupy the bandwith. This diversify is achieved without any bandwidth expansion of the group of stereo channels rela-tive to fixed single channel per carrier assignment.

Title: Power control device wherein a bias voltage in level detection is given a constant difference from a detected voltage
Inventor: INOKUCHI HIROYUKI
IPC: H04B7/005
Filed: 1993-06-04
Abstract: In a level detector (17), a bias voltage is developed by a bias current to have a substantially constant difference irrespective of a temperature variation from a detected voltage produced by detecting a device output signal for use in TDM modulation.  A control signal generator (19) calculates a substantially temperature independent difference digital value by subtracting from a first digital value of the detected voltage and a second digital value of the bias voltage to produce an attenuation control analog level used in controlling a variable attenuator (11) which deals with a device input signal to produce an attenuator output signal with a desired value for use as the device output signal.  Preferably, the detected and the bias voltages are amplified by a variable gain amplifier (35) controlled by a processor output signal.

IPC: A61P37/00
Filed: 1992-04-24
Abstract: 2102229 9219732 PCTABS00160 L'objet de l'invention est une nouvelle structure d'oligonucléotides antisens ou sens, les oligonucléotides fermés. L'invention concerne l'utilisation des oligonucléotides fermés - pouvant être avantageusement par exemple des oligonucléotides circulaires - à des fins pharmacologiques, comme molécules antisens ou sens. L'invention concerne également les méthodes d'obtention de telles molécules par des voies chimiques et/ou biologiques. L'utilisation thérapeutique des oligonucléotides comme agents antisens ou sens soulève plusieurs problèmes, dont principalement celui de la stabilité de ces molécules. Les oligonucléotides antisens sont sujet à dégradation nucléolytique, et sont principalement sensibles aux exonucléase. Les antisens fermés qui font l'objet de la présente invention sont des molécules qui ne présentent pas d'extrémités libres et qui présentent donc une résistance accrue aux attaques exonucléasiques. Les oligonucléotides fermés peuvent donc agir comme facteurs antisens avec une plus grande pérennité que les oligonucléotides linéaires correspondants. De plus, des oligonucléotides antisens fermés - circulaires ou de structure secondaire complexe - permettent de prendre en compte les structures secondaires et tertiaires des ARN messagers cibles. Par exemple, de tels antisens peuvent être multifonctionnels, et interagir avec plusieurs régions non contiguës de l'ARN cible. De plus, des oligonucléotides fermés peuvent être utilisés selon une stratégie de type "sens" pour interagir de façon spécifique avec des facteurs protéiques présentant une affinité pour certaines séquences et structures de l'ARN ou de l'ADN. De façon générale, les oligonucléotides fermés, en particulier circulaires, faisant l'objet de l'invention décrite ici pourront être utilisés dans tous les cas où il sera avantageux de disposer d'un oligonucléotide présentant une résistance accrue aux exonucléases par rapport à un oligonucléotide de même séquence mais linéaire.
