Abstract: The instant invention is a method for achieving a-planar framing configurations which enable the construction of hyperbolic paraboloid surfaces, a multiplicity of which join to create roof structures and enclosures. In particular, the shaping and erecting of connected a-planar quadrilateral frames to create under-framing which can be completed by a simple in-framing, and covered with sheeting material resulting in a new method of constructing enclosures with hyperbolic paraboloid faces without the use of highly trained crews, or the need for elaborate pre-forms or specialized connecting or covering elements.

Abstract: A gas turbine engine turbine cooling system includes an impeller and a diffuser directly downstream of the impeller, a bleed for bleeding clean cooling air from downstream of the diffuser, and one or more channels in fluid communication with the bleed. Each of the channels having a generally radially extending section followed by a generally axially aftwardly extending section terminating at an annular cooling air plenum connected to accelerators. The radially and axially aftwardly extending sections may be connected by a bend section of the cooling air channel and the axially aftwardly extending section may be angled radially inwardly going from the bend section to the cooling air plenum. Each of the cooling channels includes an inner wall formed by a forward end wall extending radially outwardly from an inner combustor casing, an annular cover covering a radially inner portion of the forward end wall, and the inner combustor casing.

Abstract: A gas turbine engine centrifugal compressor axial forward thrust apparatus bleeds impeller tip aft bleed flow from between an annular centrifugal compressor impeller of a high pressure rotor and a diffuser directly downstream of the impeller. The apparatus then uses the aft bleed flow to pressurize an annular cavity extending radially between an inner combustor casing and the rotor and extending axially between forward and aft thrust balance seals. Forward and aft thrust balance lands are in sealing engagement with the forward and aft thrust balance seals on the high pressure rotor respectively. An annular stator plenum in fluid communication with the annular cavity is bounded in part by a forward end wall having conical diffusion holes therethrough which may be axially or circumferentially or axially and circumferentially angled. The forward thrust balance seal may be on an aft conical arm of the impeller.

Abstract: The instant invention employs the impressive capabilities of modern materials such as plastics, composites, and metal alloys of carrying large tension forces, enabling them to carry compression loads by converting the compressive force of internally contained pressurized fluids into distributed tension forces. The walls and membranes of the pressurized elements, and of the envelopes are not “inflated” as in structures made of flaccid or stretchable materials, but are made of substantially rigid materials whose rigidity is enhanced by the fluid pressures contained within. An important application of the principals set forth herein will be in the use of very high tensile strength materials such as titanium or aluminum that are not often considered for use in compression. The significant weight-savings so achieved make possible new applications that might include exotic airframes: lighter-than-air craft, or small robotic solar-powered aircraft to be used for survey, surveillance, or communication.

Abstract: The instant invention is a method for achieving a-planar framing configurations which enable the construction of hyperbolic paraboloid surfaces, a multiplicity of which join to create roof structures and enclosures. In particular, the shaping and erecting of connected a-planar quadrilateral frames to create under-framing which can be completed by a simple in-framing, and covered with sheeting material resulting in a new method of constructing enclosures with hyperbolic paraboloid faces without the use of highly trained crews, or the need for elaborate pre-forms or specialized connecting or covering elements. The instant invention has the advantage that lateral forces are resolved directly along the leg members forming triangular openings at its periphery, and by the triangular configurations resulting when the tension restraining member is added to the framework. Triangular openings formed during construction can be used for doorways and windows without the need for dormers or skylights.

Abstract: The instant invention is an arrangement wherein a set of devices are enabled to signal each other either individually or as a group, and are attached, inserted, or integrated into various items in order to locate such items when they are lost, or to secure them, or otherwise keep track of them; or also any arrangement and deployment of electronic components, modules, etc (one example of which might be standard RFID chips such as are used in inventory control), such that a group of important but easily lost items, (such as wallet, keychain, calendar, and briefcase) can signal to one another so that a lost item can be “beeped” so that its whereabouts can be discovered. Additionally, the devices may be configured to signal the others if or when mutual contact is broken.

Abstract: Methods and devices are adapted for regulating fluid flow to and from a region of a patient's lung, such as to achieve a desired fluid flow dynamic to a lung region during respiration and/or to induce collapse in one or more lung regions. Pursuant to an exemplary procedure, an identified region of the lung is targeted for treatment. The targeted lung region is then bronchially isolated to regulate airflow into and/or out of the targeted lung region through one or more bronchial passageways that feed air to the targeted lung region.

Compositions in accordance with the invention comprise a metal component, Si3N4, and a sintering aid so that the targets will successfully sputter without cracking, etc. The components are combined in powder form and pressure consolidated under heated conditions for a time sufficient to form a consolidated blend having an actual density of greater that about 95% of the theoretical density. The consolidated blend may then be machined so as to provide the final desired target shape.

Abstract: A radio-frequency (RF) radiation suppressor component for use with magnetrons that reduces spurious leakage radiation by absorbing RF radiation, that seats a metal ring connector fixture for making electrical contact to the cathode of the magnetron, and that exhibits improved tolerance of higher operating voltages. An insulated RF suppressor component is comprised of an insulating sleeve member and an outer shell cladding layer made of molded composite iron powder/epoxy resin material that absorbs part of the RF radiation and thus acts as an absorber to reduce magnetron radiation leakage. The insulating sleeve end has a ridged groove indentation to seat a metal clamping ring that contacts the magnetron cathode and provides a terminal connection for the cathode voltage bias and filament heating circuit leads. Testing of prototypes indicates significant improvement in permissible operating voltages and comparable RF suppression compared to conventional RF suppressor components currently in use.
