Abstract: 11769:RD5 Abstract of the Disclosure An adjustable louver blade assembly including a number of horizontally extending, movable louver blades is described.  Each of the blades is formed in a generally hollow airfoil shaped cross section having a leading edge and a trailing edge.  Trips for inducing turbulent flow of the boundary layer are embossed on the blade surfaces and air flow seal strips can be secured to the trailing edge of each blade.  Reinforcing spacer ribbons are frictionally secured within each blade to rigidize the blade.  The pivotal axis of each blade is located so that the axis is forward of the center of aerodynamic force exerted on the blade for all attitudes of the blade between a closed position and a position about 60° from the closed position.  Blade pivot axis spacing is such that in the fully closed position, the trailing edge of a blade contacts the adjacent blade along its leading edge.  A control rod is connected to each of the louver blades so that all of the blades can be simultaneously swung to any attitude between fully open and fully closed. Each of the blades has chevron shaped slits with inwardly bent tabs near the trailing and leading edges of the blade to guide water on the surface of the blade into the hollow blade.  Water is discharged from exit ports at the blade end into open vertical channels in the side frames which conduct water to hollow corner conduits for discharge.  The frame that houses the louver blade assembly has a wall trap along the top to conduct water flowing down the outside of a supporting wall to the open channels at the side of the louver so that the water does not drip from the frame onto the louver blades,and thus be blown through the louver.

Abstract: ABSTRACT OF THE DISCLOSURE     A variable volume pump for satisfying the requirements of a hydraulic system while limiting fluid flow when the full volume of fluid displacement from the pump is not required by the hydraulic system. The pump includes one or more lines of reciprocable pumping pistons mounted radially around a crankshaft. The rotation of the crankshaft results in centrifugal flow of fluid through crankpin apertures for filling the pumping pistons. Each pumping piston reciprocates within a pumping chamber and the fluid volume filling the piston is directed through a discharge port to the hydraulic system. A valve piston is mounted within the pumping chamber in spaced apart opposing relationship to the pumping piston. The valve piston is normally scated against a valve seat when the pressure level in the hydraulic system is below that necessary to reduce flow. When the pressure in the hydraulic system reaches a predetermined level, compensating pressure is communicated against the valve piston which results in the movement of the valve piston towards the pumping piston. At a maximum desired system pressure, the valve piston contacts the pumping piston and follows the pumping piston during its suction stroke thereby limiting or blocking the fluid flow out the discharge port. Thus, the fluid flowfrom the pump is reduced in proportion to increased system pressure until a maximum desired output pressure is reached with minimum fluid flow.

Abstract: The subsea wellhead system includes a wellhead, a housing seat disposed and connected to the wellhead, a casing hanger landed and supported by the housing seat, a holddown and sealing assembly disposed in the annulus between the wellhead and casing hanger, a running tool attached to the casing hanger for lowering the casing hanger into the well and for initially actuating the holddown and sealing assembly, and other apparatus for applying hydraulic pressure to further actuate the seal of the holddown and sealing assembly. The housing seat and wellhead are connected by a breech block connection. The housing seat maintains a full 360.degree. circumferential bearing surface with the casing hanger. The holddown and seal assembly includes an upper rotating member threadingly engaging the casing hanger and suspending a lower stationary member. The stationary member includes a Z-shaped portion composed of a plurality of frustoconical metal rings connected together by connector links so as to provide a positive connective link throughout the stationary member. The annular links form grooves for housing resilient elastomeric members where, upon the compression of the Z-shaped portion of the stationary member, the elastomeric members initially sealingly engage the wellhead and casing hanger and then, upon further compression, the annular links deform into metal-to-metal engagement with the wellhead and casing hanger so as to form a metal-to-metal primary seal. The seal is actuated initally by the application of torque through a running tool connected to the casing hanger. The seal is further actuated by the application of hydraulic pressure below the blowout preventer whereby a compression set of the seal is achieved which is greater than the working pressure of the well. The rotating member of the holddown and seal assembly follows the further compression of the seal so as to prevent the release of the compression set upon the removal of the hydraulic pressure.

Abstract: CHAMBER To ASSURE RELIABLE INFUSION     OF MEDICAMENTS AND THE LIKE            Abstract of the Disclosure In a fluid administration set of otherwise conven-tional design, an in-line chamber is provided having an inlet and outlet port communicating with the chamber and defining part of the path of flow through the set.  A sealing piston is slidably movable by fluid pressure within the chamber and capable of occupying first positions in which the sealing piston isolates fluid in the chamber adjacent the inlet port from fluid in the chamber adjacent the outlet port.  The sealing piston also can occupy at least one second position in which unlimited fluid flow is permitted between the inlet port and outlet port.  A third port is provided for intermittently insert-ing a critical fluid into the chamber on the side of the sealing piston facing the outlet port.  Thus the piston can be driven into the first position from the second position by this insertion, to prevent mixing of the critical fluid with fluid on the side of the piston facing the inlet port until the critical fluid has substantially passed through the outlet port and the piston moves to the second position.  This permits the reliable, prompt admin-istration of essentially the entire dose of a critical medication, particularly at low flow rates.

Abstract: ABSTRACT           A broadband non-resonant microwave frequency halver which simultaneously decouples the input frequency from the output port through phase cancellation and couples the sub-harmonic frequency to the output port through phase addition providing good isolation between input and output over a very broad frequency range.  The implementation of this circuit specifically excludes resonant, or frequency dependent elements and therefore has a much broader band of operation than previous circuits which relied on resonant phenomena.
