Title: Fuzzy control apparatus in which rules can be changed, method of operating same, control system in which changeover is controlled by fuzzy reasoning, and method of controlling thesame
Inventor: HISHIDAI HAJIME
IPC: G06N7/02
Filed: 1990-07-10
Granted: 1997-12-09
Abstract: In a fuzzy control apparatus in which a rule is capable of being changed during operation, a fuzzy reasoning output which prevails immediately prior to a rule change is stored when a rule change is made, and a fuzzy-control output is generated by combining, after the rule change, the stored fuzzy reasoning output which prevailed immediately prior to the rule change and a fuzzy reasoning output which prevails following the rule change.  The ratio of the combination is altered in such a manner that, with the passage of time from the moment at which the rule change is made, there is a gradual decrease in a percentage of the fuzzy reasoning output which prevailed immediately prior to the rule change, and a gradual increase in a percentage of the fuzzy reasoning output which prevails following the rule change, in the fuzzy-control output.  Upon passage of a predetermined time from the moment at which the rule change is made, the fuzzy reasoning output which prevails following the rule change is outputted as the fuzzy-control output.  As a result, a sudden change in the output at the time of a rule change is prevented so that a smooth changeover can be carried out.

Abstract: A halyard retainer (10) eliminates noise created by the halyard (12) hitting a flagstaff (14) by retaining the halyard (12)  at a greater distance than would normally separate the halyard (12) from the flagstaff (14).  A base (30) fixedly secures the halyard retainer (10) to the flagstaff (14).  The halyard restrictor (24) is at the distal end (20)  of an arm (16)  and includes two slots (26).  The longitudinal portions (28) of the slots (26) allow the halyard retainer (10) to hold the halyard (12)  without additional latches or locks.          The arm (16) is rotatable about a first pin (42) between  an  operating  position  and  a  storage position  and  is  locked  into  one  of  the  two positions using a second pin (58).

Title: Analogs of glycoprotein hormones having altered immunological characteristics, efficacy and/or receptor specificity
Inventor: CAMPBELL ROBERT K
IPC: C07K19/00
Filed: 1991-05-07
Granted: 2003-09-23
Abstract: The invention relates to modified chorionic gonadotropin (CG) alpha, beta-heterodimeric polypeptides comprising a gly-coprotein hormone alpha-subunit polypeptide and a non-naturally occurring beta-subunit polypeptide. The modifications in the beta-subunit polypeptide involve tho deletion, addition, or substitution of one or more amino acid residues. The modified heter-odimeric polypeptides of the invention have different properties compared to native hCG. Certain alpha, beta-heterodimeric pol-ypeptides bind to LH and FSH receptors and stimulate steroidogenesis in testicular and ovarian cells. Other alpha, beta-heterodi-meric polypeptides bind to LH receptors but have lower efficacy than hCG to stimulate steroidogenesis in testicular and ovarian cells.

Patent CA-2093712-C (CA)
Title: Apparatus and methods for reducing fuel/air concentration oscillations in gas turbine combustors
Inventor: BLACK STEPHEN H
IPC: F23D14/02
Filed: 1993-04-08
Granted: 2003-07-15
Abstract: A lean burn gas turbine combustor has a premixer zone receiving compressor discharge air through openings in a combustor liner. A fuel nozzle has an upstream orifice 52, a downstream orifice 56, and a captured response volume 54 therebetween. Upstream orifice 52 affords a high pressure drop for gaseous fuel to approximately the pressure of the compressor discharge air. The low pressure discharge orifice affords a pressure drop comparable to the pressure drop across the openings of the combustor liner for the air supply. The dynamic pressure response characteristics of the fuel and air inlets to the premixer zone are substantially matched to eliminate variations in fuel/air concentration resulting from pressure variations in the premixer zone. The captured response volume between the upstream and downstream orifices is sized sufficiently to store enough fuel to accommodate the mismatch in phase angle of fuel flowing into the captured response volume through the upstream orifice at a first phase angle relative to the phase angle of a pressure forcing function in the premixer zone and fuel flowing out of the captured response volume through the downstream fuel discharge orifice at a second phase angle relative to the phase angle of the pressure forcing function.

Granted: 2004-07-27
Abstract: A method of operating a regenerative glass furnace for melting glass for the manufacture of shaped glass articles so as to minimise emission of NOx in waste gases leaving the furnace, the furnace having sealed regenerators which act as heat exchangers, the method comprising supplying fuel in excess of that required for stoichiometric combustion to ensure that glass of the required quality at the required production rate is obtained, and that the waste gases leaving the furnace through the regenerators contain combustible material, and reacting said combustible material with sufficient air to ensure that the waste gases exiting to atmosphere contain permissible levels of combustible material and contain permissible levels of NOx.      Alternatively, the furnace may be operated at substantially stoichiometric conditions and fuel is supplied to waste gases as they leave the melting chamber. The invention also relates to a regenerator glass furnace for use in the method. The invention further provides a method of reducing the emissions of CO in waste gases leaving a cross-fired regenerative glass furnace for melting glass for the manufacture of shaped glass articles, the furnace having sealed regenerators which act as heat exchangers, the method comprising removing CO from the waste gases in the regenerator by combusting CO in around 8% excess air, based on the combustion air for the supplied fuel, at a temperature greater than 650°C.
