Patent WO-8604959-A1 (WO)
Inventor: TING HUI-TZENG
IPC: F02M7/14
Filed: 1985-02-13
Abstract: Un gicleur mobile de carburant émis sous basse pression par un groupe de petits trous répartis sur une surface est associé à la plaque d'étranglement (7) d'un carburateur de sorte que la quantité en excès de carburant sous des conditions de charge partielle tombe dans une zone de drainage et s'écoule dans un réceptacle (6) d'où elle retourne au réservoir de carburant par une canalisation de débordement. Le réceptacle (6) a un niveau de carburant fixe pour servir un système de ralenti. Une pompe de carburant entraînée par le moteur fournit pour chaque temps d'admission du moteur une quantité fixe de carburant au gicleur mobile et à un dispositif de dérivation (9) qui possède une ouverture variable pour dévier une partie du carburant vers la zone de drainage en fonction de la vitesse du moteur.

Abstract: FINGER JOINTING GREEN LUMBER                    ABSTRACT OF DISCLOSURE           Finger  jointed  lumber  is  produced  from  discrete green lumber pieces each formed with a first set of fingers on one end and a second set of fingers at the other end.  The first  set  of  fingers  is  dried  by rapidly  applying  heat substantially solely through the  first set of fingers in a first  drying station.   The  second  set  of  fingers  is then rapidly dried in a second drying station.   A thermo-setting adhesive  is  applied to the  second set of  fingers  of each lumber piece while still hot and the second set of fingers on one piece and the first fingers on an adjacent lumber piece are mated and crowded together to form a joint.  The adhesive is significantly cured by residual heat in the mating ends before significant moisture migrates back to the fingers from the bodies of the mating lumber pieces and interferes with the curing of the adhesive.

Abstract: A method of winding a belt-shaped member is used in winding a tire member around a forming drum.          A position of a leading end of a tire member is detected to obtain a shifted distance of the leading end relative to the forming drum.  The leading end is then transferred to the forming drum, while the leading end is being moved in a width direction to make zero the shifted distance.  The leading end is pressed against the forming drum, while the leading end is brought into coincidence with a reference position of the forming drum. The forming drum is then rotated during which the tire member is suppled onto the forming drum.          A position of a trailing end of the tire member is detected to obtain a shifted distance of the trailing end relative to the reference position of the forming drum.  The trailing end is the supplied onto the rotating forming drum, while the trailing end is moved in a width direction to make zero the shifted distance of the trailing end.  In this manner the tire member is completely wound about the forming drum with the leading end being snugly coincident with the trailing end.

Title: Method and apparatus for precision attitude determination and kinematic positioning
Inventor: HATCH RONALD R
IPC: G01S19/48
Filed: 1990-09-21
Abstract: A technique for resolving whole-cycle ambiguity that is inherent in phase-angle measurements of signals received from multiple satellite-based transmitters in a global positioning system. The relative position of a secondary receiving antenna with respect to a reference antenna is approximately known or approximately initially determined and then measurements from a minimum number of satellites are used to determine an initial set of potential solutions to the relative position of the secondary antenna that fall within a region of uncertainty surrounding the approximate position. Redundant measurements are taken from one or more additional satellites and used to progressively reduce the number of potential solutions to close to one. Even if the number of potential solutions is not reduced to one true solution, the number can be further reduced by using additional measurements taken at different time intervals, at which different satellite geometries prevail. The disclosed technique produces rapid elimination of false solutions and permits real-time computation of relative position in kinetic positioning applications, and of angular orientation in attitude determination applications.

Abstract: Abstract of the Disclosure A shuttle control for a storage and retrieval machine has a supervisory control means mounted on the base of the storage and retrieval machine and shuttle control means mounted on the carriage of the storage and retrieval machine.  The supervisory control means receives shuttle operating commands and information signals and provides operating instruction signals for the shuttle to the shuttle control means.  The shuttle control means receives the operating instruction signals from the supervisory control means, produces operating information signals to the supervisory control means, and controls the operation of a shuttle motor drive.  Circuit means having sliding contactors moving with the carriage on vertical slide bars mounted on the mast transmit operating instruction signals and information signals between the supervisory control means and the shuttle control means at a maximum transmission rate limited by the problems of transmitting the signals through the sliding contact means.  Sensing means mounted on the carriage of the storage and retrieval machine produce shuttle operating condition indicating signals to the shuttle control means at a transmission rate faster that the maximum transmission rate of the circuit means.  The indicating signals are used by the shuttle control means to control the operation of the shuttle motor.

Filed: 1990-10-22
Abstract: SAND  CONSOLIDATION METHOD      (D#79,192-F) ABSTRACT         This invention relates to a method of treating wells completed in subterranean formations containing unconsolidated sand particles, so as to form a permeable barrier which permits relatively free flow of liquids including petroleum therethrough while restraining the flow of sand particles into the wellbore.          The method comprises formulating a treating fluid containing a compound which undergoes acid catalyzed polymerization, preferably an oligomer of furfuryl alcohol, and an anhydride of a strong acid such as phosphorous tribromide mixed in a suitable diluent such as methyl isobutyl ketone.  The composition is injected into the formation.  The anhydride reacts with trace amounts of water forming an acid which catalyzes the polymer.          Polymerization produces more water to react with additional anhydride.  The water content of the treating zone must be less than five percent by volume based on the volume of the pore volume of the treating zone, which usually requires a pre-treatment to remove water from the treatment zone, such as a preflush with a non aqueous fluid.
