Abstract: A self regulating bleed valve for a gas turbine engine is provided which taps or bleeds a portion of a gas, typically air, from a duct of the gas turbine having a wall bounding the gas flow. The bleed valve has a valve member pivotally attached to the wall such that the valve member extends through a main opening formed in the wall. The valve member has an internal cavity in communication with a gas inlet opening and a gas exhaust opening and is pivotally movable between an extended position wherein the gas inlet opening portion of the valve member extends into the gas flow duct such that the inlet opening faces generally in an upstream direction so as to deflect a portion of gas flow into the internal cavity, and a retracted position wherein the inlet opening extends obliquely, generally parallel, to the gas flow so as to minimize the air tapped or bled from the gas flow.

Abstract: A method of and system for paging mobile stations within a cellular telecommunication system wherein the allocation of control channel paging capacity is optimized. Each page request for a mobile station received by the system is classified into a predesignated group based upon the characteristics of the request, such as the degree of certainty with which the location of the mobile is known and the origin of the page request. In accordance with the predesignated group to which the page request is assigned, each page request is assigned a paging extent designation to be associated with one or more page attempts and representing the geographic area within the system to which each page attempt is to be broadcast. A paging priority is then assigned to each page attempt based upon the previously assigned group characteristics and paging patterns. Each page attempt is executed within the system according to its designated priority.

Abstract: A multifunctional visceral catheter having a self-guiding system in the form of a pair of fiberoptic sensor systems which are sensitive to a predetermined analyte, the analyte being one which is removed from the vascular circuit of interest to a high degree, such as galactose in the hepatic venous system or creatinine in the renal venous system. One of the sensors is disposed on the catheter so as to be positioned within the venous system of interest, while the other sensor remains outside the venous system in the vena cava. A substantial difference between analyte concentration values as measured via the two fiberoptic sensor systems provides immediate confirmation that the catheter is properly positioned. In addition to being self-guiding, the catheter provides for direct sampling of venous blood; includes a fiberoptic system for continuously monitoring oxygen saturation in the hepatic or renal venous blood; and is capable of measuring absolute hepatic or renal blood flow.

Abstract: A shrink wrap or stretch wrap pallet system including a pair of end panels arranged and configured so as to mount on opposite sides of a package, effectively connecting a base pallet and a top panel. The end panels themselves are spaced from the perimeter of the package. The end panels have vertical edges which extend beyond the perimeter of the package, thereby defining a plane between respective end panels, the plane serving to space the wrap, which lies substantially therein, from the package. The end panels are conveniently sized and shaped to fit within the area of the base pallet, intermediate panels and top panel thereby providing a relatively compact return package. Side panels may be provided to supplement the end panels.

The locking bar has a slot at one end for engaging and capturing the door knob shaft to prevent its rotation. When the orientation of the locking bar is reversed, the locking bar rests on the shoulder of the recess and does not engage the door knob shaft.

Abstract: A gas flow separator for an annular combustion chamber of a gas turbine engine is disclosed in which the radially spaced apart first and second gas flow separator walls which extend axially into the combustion chamber from the combustion chamber upstream end wall each define a plurality of axially extending channels. Each of the channels extends generally axially in an upstream direction from the downstream edge of each of the separator walls such that their axial lengths are less than the axial lengths of the respective separator walls. Both the depth and the width of each of the channels increases from its upstream end point to the downstream edges of the separator walls. The channels may be circumferentially aligned with each other, or the channels of one separator wall may be circumferentially offset from the channels of the other separator wall.

Abstract: An applicator system for applying color coating on a paper web is disclosed having a color coating applicator along with a backing roll around which is wrapped the paper web. A measuring system is incorporated for measuring a predetermined property of the color coating at several points along the width of the paper web. Predetermined qualities of the color coating include weight, thickness, or surface properties of the coated surface. A control means is included for controlling the color coating arriving at the application zone. The color coating is controlled by varying the temperature, or the consistency of the color coating in a zonewise fashion across the width of the paper web.

Abstract: A method and apparatus for providing an enhanced Call Forwarding Don't Answer feature is disclosed. When an originating address calls a base address assigned the Call forwarding Don't Answer feature and the call is forwarded to a remote address, a Look Ahead feature is implemented. The Look Ahead feature determines if a call setup to a remote address is successful, unsuccessful or points out a feature assigned to the remote line. The originating address is provided with ring tone during the call setup. The call setup results are then used to make appropriate connections to implement the functions of the feature while providing a steady ring tone to the originating address.

Abstract: A fuel supply system for a gas turbine engine is disclosed which incorporates a discharge conduit into the fuel supply system such that an increase in the temperature of the fuel in the fuel injector conduits after engine shut-down will cause a valve in the discharge line to open before the opening of the valve in the fuel injector conduit, thereby directing excess fuel to a receiver or a tank, rather than into the hot combustion chamber. A fuel flow valve is connected to the fuel supply conduit, the discharge conduit, as well as the fuel injector conduits. Under normal operating conditions, a valve member within the fuel flow valve is positioned so as to enable communication between the fuel feed conduit and the fuel injector conduits so that fuel may be supplied to the fuel injectors. When the valve element is moved the a second position, after engine shut-down, it seals off the fuel feed conduit and enables communication between the fuel injector conduits and the discharge conduit.

Abstract: A valve comprises a valve body having threaded connections on each end. A unit handled valve mechanism includes a cage carrying a spring loaded floating valve ball. The valve mechanism is placed in and removed from the valve body without the use of special tools. The valve mechanism includes lip type polyseals allowing pressure from below to leak past a lower valve seat so pressure from below causes the valve ball to seal only against an upper seat assembly. The only segment of the valve ball in substantial compression is immediately adjacent the upper seat assembly. An actuator for the valve fits onto a connector between the actuator and ball in only one manner, so the indicator on the actuator correctly points at the correct indicia on the valve body describing the valve condition, i.e. open or closed. An improved connector between the actuator and the valve ball minimizes the potential of deformation due to abuse.

The unknown coordinates are identified based on a generalized information signal E.sub..SIGMA. =e.sub.1.sup.2 +e.sub.2.sup.3 +e.sub.3.sup.2, where e.sub.1 (i=1, 2, 3) is the amplitude of signals induced in the three bi-orthogonal receiver induction coils in each of the magnetometric sensors.
