Title: Methods of delivering multiple channels of audio and video by radio communications and cable
Inventor: RUTHERFORD JOHN G
IPC: H01Q1/12
Filed: 1992-10-19
Abstract: ABSTRACT          The invention comprises the use  of  a  community  communications facility  that  minimises  the  need  for   individual   consumer equipment that in the case of antennas of the dish variety,  make unsightly appendages to residential or commercial properties, and in the case of electronics for receipt and transmission of  video and   audio   services,   encryption,   decoding,    compression, digitising,  and  other  high  technology  transmission   related activities, such are  expensive  and  often  impractical  if  the transmissions being received are too weak from  distant  sources, or if terrestrial, are shaded by buidings  or  terrain  features, from the equipment of the end user.          The high cost of trunk coaxial or fibreoptic cabling, shortage of radio spectrum, and cost of satellites  capable  of  transmission direct to consumers and receivable on  small  dishes,  makes  the concept  of  community  antenna  and  communications   facilities desirable for use with  short  range  consumer  transmission  and reception equipment  particularly  of  the  type  appropriate  to microcellular radio telephony and interactive  TV  transmissions. The combined use of radio  and  cable  transmissions  over  short distances to and from the premises of end users, and thence  from the community transmission  facility  to  hilltop  retransmission facilities  or  direct  to  satellite;  offers  flexibility   and economy, and has benefits in  respect  to  copyright  laws  where receipt of long range  broadcast  transmissions  by  viewers  and listeners would otherwise be a breach of copyright laws.

Patent CA-2088546-A1 (CA)
Title: Gas-blast circuit breaker
Inventor: HILTBRUNNER HUGO
IPC: H01H33/915
Filed: 1993-02-01
Abstract: The gas-blast circuit breaker has passages in the pump piston which connect the pump space to the arcing space and to the surrounding space. These passages are held closed during switching-off and open during switching-on by valve devices. For this purpose, the pump piston is used as a valve seat and the annular disk is used as a valve body which is common to the first valve and to the second valve, the first valve controlling the passage between the pump space and the surrounding space, and the second valve controlling the passage between the pump space and the arcing space. When switching-off large currents, the piston is subjected to an overpressure in the switching-off direction, which overpressure is produced by switching gas flowing into the arcing space, in order to support the drive. The valves are prevented from opening, by means of the pressure in the pump space. During switching-on, the annular disk is raised off the pump piston against the spring prestressing, by means of the reduced pressure in the pump space and the overpressure in the arcing space, in order to connect these two spaces to the surrounding space and to ensure pressure equalization without the drive having to apply more energy during switching-on than in the case of a circuit breaker without an arcing space.

Title: Method for correcting spectral and imaging data and for using such corrected data in magnet shimming
Inventor: DUNKEL REINHARD
IPC: G01R33/46
Filed: 1992-03-24
Abstract: Spectral and imaging data (Fig. 9, Fig. 15, Fig. 18) is corrected for various types of distorsion, such as phase and baseline distorsion, by fitting a mathematical model of the expected data to the experimental data. The model includes parameters relating to the distorsions to be corrected. The model is fitted to the data by adjusting model parameters, generally through a regression analysis, and when a best fit is obtained, the parameters resulting in the best fit provide the information necessary to correct the data. The inventive method is used to produce phase and baseline corrected spectra (Fig. 10, Fig. 16, Fig. 21), or the corrected data is used in magnetic shimming, wherein phased spectral data is used with a magnetic shim coil distorsion model, or with moment minimization of resonance frequency distribution to direct magnet shimming.

IPC: C07C41/01
Filed: 1994-01-25
Abstract: An oxygenated organic liquid product and a fuel gas are produced from a portion of synthesis gas comprising hydrogen, carbon monoxide, carbon dioxide, and sulfur-containing compounds in a integrated feed treatment and catalytic reaction system.  To prevent catalyst poisoning, the sulfur-containing compounds in the reactor feed are absorbed in a liquid comprising the reactor product, and the resulting sulfur-containing liquid is regenerated by stripping with untreated synthesis gas from the reactor. Stripping offgas is combined with the remaining synthesis gas to provide a fuel gas product.  A portion of the regenerated liquid is used as makeup to the absorber and the remainder is withdrawn as a liquid product.  The method is particularly useful for integration with a combined cycle coal gasification system utilizing a gas turbine for electric power generation.

Title: Liposomal Antibiotic Formulation
Inventor: SHEK PANG N
IPC: A61K31/54
Filed: 1994-03-04
Abstract: The drugs of choice for treating intra-abdominal sepsis caused by infection with Gram negative bacteria include .beta.-lactams such as cefoxitin. However, unless the drugs are administered within 8 to 12 hours post-infection, the infecting microbes rapidly gain entry to and reside in cells of the reticuloendothelial system, where the microbes appear to become shielded from further drug action. It has been found that a liposomal cefoxitin formulation is effective in reducing the bacterial counts and the mortality of animals suffering from intra-abdominal Gram negative sepsis. The preferred liposome is phosphatidylcholine and phosphatidylserine in the molar ratio of from 9.5:0.5 to 1:1.

Abstract: An automatic calling service is provided wherein a subscriber predefines one or more destination telephone numbers, and calls to such number or numbers are billed to the subscriber's local telephone number. Calls are made to such destination numbers through a platform that may be reached via a toll free number. The calling party identifies him/herself as a subscriber, by entering a personal identification number, to authenticate him/herself as a person entitled to make such calls. Based upon the identification provided, a determination is then made as to whether thesubscriber has stored one number, or more than one number. If one number is stored, the caller need not identify the destination number, and advantageously, that number is then dialed. If more than one number has been specified, the subscriber is prompted to provide an indication of the particular number desired. The call is then completed to the desired number. In either event, the identity of the subscriber is used to assure that the call is billed to the subscriber's local telephone number. In order to reduce the possibility of unauthorized access, a determination may also be made as to whether to call is originating from an eligible location, as by checking automatic number identification (ANI) information associated with the call.
