Patent CA-2016713-A1 (CA)
Inventor: NORTON IAN T
IPC: C09K23/56
Filed: 1990-05-14
Abstract: The present invention is concerned with a process for preparing a dispersion comprising a continuous fat phase and a dispersed gelled aqueous phase, wherein a water-continuous composition, containing at least 1% gelatin by weight of water, is cooled from above the gel setting temperature of the water-continuous composition to below said gel setting temperature and subjected to such conditions of shear that the water-continuous composition is converted into small gelled aqueous beads, after which a fat-continuous dispersion is formed while maintaining the temperature at below the gel melting temperature. The process according to the invention offers the advantage that it enables the preparation of water-in-oil dispersions of extremely low fat content even when using aqueous phase compositions which in the ungelled state do not possess a high viscosity. Also the present process makes it possible to incorporate ingredients into the aqueous phase which, in the absence of a gelled structure, would promote and actually induce the formation of an oil-in-water dispersion. Another aspect of the present invention is a dispersion comprising less than 23% by weight of a continuous fat phase and a dispersed gelled aqueous phase containing gelatin at a concentration of 1 to 7 times its critical concentration and optionally a combination of one or more gelling agents other than gelatin at a concentration below their critical concentration.

IPC: G06F11/22
Filed: 1990-05-31
Abstract: A TECHNIQUE FOR PRODUCING AN EXPERT SYSTEM        FOR SYSTEM FAULT DIAGNOSIS Abstract The present invention relates to a technique for operation on a computer for developing the knowledge base for ultimately providing very fast and cost-efficient fault diagnosis systems. The present technique uses a effective hierarchy of rules where at a first level are rules which allow the arrangement of the system under test to bedecomposed into a hierarchy of sequential and parallel subsystems. At the second level are rules that generate the efficient testing rules for each pure subsystem. The second level rules can be compared to a node evaluation function in a typical problem of searching a graph to select the best node for expansion from a current list of candidate nodes, so that the best path to the correct system diagnosis is found in the shortest amount of time using a minimum of user input. Two heuristic rules are applied tospeed-up the process of selecting the node as the best candidate for expansion. The resultant hierarchy of rules permit the cost-efficient knowledge base and resultant output test tree procedure to be generated for a fault diagnosis system to be applied for testing an associated device or system.

Filed: 1990-08-22
Abstract: ABSTRACT         A method and apparatus for trimming a boat to adjust the angle of attack of the boat relative to the water, which comprises passing the boat through the water at a speed sufficient to cause an intake conduit means located on the after portion of the hull, and preferably at the stern of the boat to receive water.   The received water is passed from the stern via a transfer conduit means to the bow of the boat.  The received water is then expelled downwardly out of the bow via a discharge nozzle at a velocity sufficient to create a reaction force great enough to create a bow-lifting moment upon the boat hull.  In addition, the trim system further includes means for controlling the velocity of flow of the water expelled from the discharge nozzle to thereby control the reaction force and the bow-lifting moment.

Title: Method for the preparation of a stabilized catalyst for the polymerization of olefins
Inventor: FUNABASHI HIDEO
IPC: C08F4/651
Filed: 1990-09-13
Abstract: ABSTRACT OF THE DISCLOSURE            METHOD FOR THE PREPARATION OF A STABILIZED CATALYST FOR THE POLYMERIZATON OF OLEFINS      A so-called Ziegler catalyst composed of a titanium halide-containing solid ingredient and an organoaluminum compound for the polymerization of olefins can be imparted with greatly improved storage stability by first subjecting the catalytic composition to a pre-polymerization treatment and then to a contacting treatment with carbon dioxide and/or carbon monoxide. The catalytic activity is almost unchanged even after storage of the stabilizedf catalyst for 90 days or longer in nitrogen gas.  The stabilized catalyst can also be used advantageously in a continuous-process polymerization of propylene by continuously introducing the monomer carrying the catalyst owing to absence of blocking of the pipe line with the polymer formed in-line.

Title: System for precisely controlling discharge rates of loss-in-weight feeder systems
Inventor: JOHNSON NORMAN R
IPC: G01G13/29
Filed: 1990-10-30
Abstract: System for controlling the discharge rate of a material feeder. A weight scale connected to the material is sampled and the samples input to a digital processor. The digital processor determines for consecutive time intervals during discharge of said material, a [AV] weight loss over the time interval. The [AV] weight loss for the interval is compared with a desired weight loss which is calculated from a desired setpoint material discharge rate. The resulting error is averaged with subsequent errors to form a control signal for the material feeder. The calculation of errors over each subsequent interval increases the resolution of the control signal, increasing the ability to control discharge rates to compensate for changes in material density which other wise affect discharge rates.

Title: Constant swing golf club set
Inventor: DAVIS C MICHAEL
IPC: A63B53/00
Filed: 1990-11-19
Abstract: ABSTRACT     A set of golf  clubs is  disclosed which includes a first set of woods and a second set of irons. The iron set includes multiple subsets. All of the irons in the set have a common club head which is the same in weight,  vertical face height and length, but different in loft angle and face width so that all the irons have the same face presentation. All of the subsets are different in shaft length, but within each  subset, the  shaft  lengths  are  the  same.          Regardless of the difference in shaft lengths,  there is a common lie and common grip line and top grip line defining a common grip about which all of the irons and woods are gripped.  This provides the same vertical hand height and a common stance and swing for all  of  the  irons  in the  set.  Counterweights disposed within the spaces increase the speed of the club head for the irons in the subsets respectively.          All subsets have a different shaft  length,   total weight,  lie angle,  and counterweight.  All subsets have the same club head weight and swing weight.  The wood set includes wood which have the same grip line and  swing  weights,   but  different  loft  angles, lengths,  and counterweights.  Accordingly,   all the clubs in the golf club set may be played with a shortened club length placing the golfer closer to the ball for more accurate hitting with  a common swing and yet with increased club head speed so that the ball goes further.

Abstract: PRODUCTION OF GASOLINE AND DISTILLATE FUELS FROM LIGHT                        CYCLE OIL                         ABSTRACT High octane gasoline and high quality distillate are co-produced by a hydrocracking light cycle oil from a catalytic cracking process under conditions of low to moderate hydrogen pressure and severity to produce a high  octane,  hydrocracked  gasoline.   The  distillate fraction from the hydrocracker is separated to form a first  fraction  which  boils  immediately  above  the gasoline fraction and a second, higher boiling fraction which is withdrawn as product.   The first distillate fraction is recycled, preferably to extinction, to the cracker to increase the paraffinic content of the higher boiling   distillate   product   by   removal   of   the hydroaromatic components in the recycled fraction. The recycled fraction may be mixed with fresh feed to the cracker or may be injected at a higher level in the cracking  riser  as  a  secondary  feed  injection.  The paraffinic distillate product has a low sulfur content and a high cetane index and is useful as a road diesel fuel.

Title: Selecting the most suitable receiver antenna from two or more receiver antennas
Inventor: EKELUND BJOERN O P
IPC: H04B7/26
Filed: 1991-04-09
Abstract: The invention relates to the selection of an antenna in a receiver of a mobile radio station which forms part of a time-multiplexed radio communication system. The signal strength of each antenna is measured in each time slot which immediately precedes the time slot intended for the station concerned, and the antenna selection is effected in dependence on the measured signal strengths. In order to eliminate the risk of unsuitable antenna selection as a result of momentary falls in signal strength, the signal strength for each antenna is measured on several occasions during the time slot in which the measurements take place. The signal-strength values for each antenna are thereafter combined linearly, so as to form a suitability measurement. The antenna having the highest suitability measurement is selected for the next arriving time slot.
