Abstract: ABSTRACT OF THE DISCLOSURE The present invention relates to motion picture special effects generation and control systems and, more particularly. to a system for simulating an effect such as an earthquake.  Prior art special effects systems require extensive modification of the theater in which they are installed, or the theater must be specially built for such systems, such as those with a vibrating floor or seats.  Additionally. prior special effects control systems requires special reproduction equipment which is not compatible with ordinary motion picture projection equipment.  The present invention overcomes the deficiencies of the prior art by providing a special effects sytem for simulating physical sensations in an audience during the presentation of a motion picture in which relatively high intensity, very low frequency random noise is acoustically coupled to a theater space to produce psychological and physiological sensations, such as earthquake movements, in the audience.  The special effects are controlled by a control sub-channel which is either frequency multiplexed onto a conventional optical audio track, or, in a magnetic stripe film format, the control sub-channel is placed on an accompanying optical track.  The presence and amplitude of two control frequencies in the sub-channel are detected and logically combined, providing four separate digital function control signals and two analog control signals which are variable in amplitude.

Abstract: ABSTRACT OF THE DISCLOSURE           Attitude of a pitch momentum biased satellite in a low inclination orbit is controlled by a closed loop magnetic torquing control system.  A magnetic dipole oriented perpendicular to the satellite's pitch axis in the roll/yaw plane and at a predetermined azimuth angle relative to the roll axis minimizes roll and yaw errors by interaction with the earth's magnetic field. Signals from an on-board roll attitude sensor are used by satellite mounted detection and driver circuits to control the compensating torques.  Magnetic torquing is initiated whenever the roll error as measured by the roll attitude sensor exceeds a predetermined threshold.

Abstract: COOLING SYSTEM FOR A THRUST VECTORING   GAS TURBINE ENGINE EXHAUST NOZZLE                                  Abstract A thrust vectoring gas turbine engine exhaust nozzle is provided with a variable area flow path wherein cooling of the stationary flow path side walls is partially obtained by the film cooling technique. Regulating means, such as a valve, is provided to control the pressure drop of the cooling fluid across the walls as a function of nozzle flow path area, thus optimizing the coolant flow rate as a function of flow path area. Where a rotating bonnet-type deflector is employed to divert the exhaust stream downward to obtain a vertical take-off and landing capability, a system is provided to cool the deflector walls by both the impingement and convection cooling techniques. A favorable pressure gradient for the cooling fluid is obtained by exhausting the cooling fluid to ambient pressure whenever the deflector is deployed. Another valve is provided to regulate the flow of coolant to an expansion flap when the deflector is in its stowed position external to the flow path.

Le procédé comprend une première étape dans laquelle on injecte, à partir du puits, dans la partie du gisement où l'on veut réduire ou annuler les venues d'eau, une solution aqueuse, stable, limpide et salée d'un polymère hydrosoluble et non réticulé P à une concentration C, la solution polymérique présentant une viscosité inversement proportionnelle à la concentration en sel, la viscosité n2 de la solution étant telle que n2 < n1 ou n1 est la viscosité d'une solution du polymère hydrosoluble P dans une échantillon de l'eau de gisement à la concentration C, la viscosité n2 étant obtenue dans la solution polymérique par la présence d'une quantité suffisante d'un sel de métal alcalin ou alcalino-terreux, ou d'un mélange de tels sels.  Dans une seconde étape, on met le puits en production d'huile et/ou de gaz, ce qui permet aux fluides présents dans le gisement de venir au contact de la zone du gisement contenant le polymère absorbé, l'huile et/ou le gaz traversant sélectivement la zone pour venir dans le puits, tandis que le passage de l'eau du gisement est réduit.

Abstract: BRAKE CONTROL VALVE DEVICE WITH MOVABLE     CONTROL RESERVOIR CHARGING VALVE                ABSTRACT OF THE DISCLOSURE       A brake control valve device operated by a reduction in brake pipe pressure on one side of a movable abutment rela-tive to control reservoir pressure on the opposite side em-bodies in the abutment a control reservoir charging valve mechanism, a filter and a choke arranged in series.  The valve mechanism comprises a spring-biased valve slidably mounted in a ported bushing carried by the abutment.  Two spaced-apart stops carried on the abutment enable relative movement between the abutment and the valve whereby, in one position of the valve, fluid under pressure may flow from the brake pipe to the control reservoir to effect charging thereof via the ported bushing, a passageway in the valve and the choke, and, in a second position of this valve, this charging communica-tion is closed.         One end of the valve abuts a member disposed therebetween and a second abutment biased in the direction of the first abutment by a strong spring.  Therefore, upon a reduction of brake pipe pressure on the one side of the one abutment to effect a brake application, control reservoir pressure on the opposite side shifts this one diaphragm and the ported bush-ing relative to the valve until a seal member carried adjacent the one end of this valve is disposed below the ports in the bushing thereby closing communication between the brake pipe and the control reservoir.

Abstract: PILOT REGULATOR                       Abstract of the Disclosure A pilot regulator for pressure regulation servo-control of a valve in a compressible fluid system includes a delay arrangement for achieving both rapid response and stable opera-tion.  The regulator includes a restrictor for supplying fluid from the main valve inlet to a control chamber, and a pilot valve for exhausting fluid from the control chamber.  A diaphragm assembly for operating the pilot valve is biased in one direction by a reference force or pressure and in the opposite direction by the static pressure to be regulated.  The control chamber and a delay chamber, in adjustable restricted communication with the control chamber, bias the diaphragm assembly in opposite directions.  When static pressure change causes movement of the diaphragm assembly and opening or closing of the pilot valve, the difference in control pressure with respect to delay pressure permits limited abrupt movement of the diaphragm assembly, and provides a gradual continued reset movement.
