Abstract: A multi lumen catheter assembly. The assembly provides an expandable, low profile, fixed length sheath and catheter, with fixed infusion ports. The assembly has an expandable outer sheath that expands upon pressure activation with a fluid and the sheath allows the fluid to exit from at least one predetermined fixed location from a distal end of the catheter assembly. The catheter assembly can be used in various medical device procedures, such as a TIPS (Transjugular Intrahepatic Portosystemic Shunt) procedure, or anywhere a low profile, multi lumen, infusion catheter system is desired.

Abstract: An emergency ejection seat adjustable along two independent axes: vertical adjustment (up and down) and horizontal adjustment (fore and aft). The ejection seat adjusts to accommodate all aircrew sizes, sitting shoulder heights, buttock-knee lengths, and functional limb reaches and is constructed of modular components which are easily removed and replaced. The ejection seat comprises a seat bucket structure, a seat insert, a linkage assembly and equipment bays. The linkage assembly interfaces between the ejection seat bucket structure and seat insert to allow both vertical and horizontal adjustment.

Abstract: A liquid treatment system for hollow articles having an open end facing downwardly upon a moving conveyor belt includes a vacuum stripper tube connected to a blower for generating a suction force withdrawing excess liquid from the hollow articles and the belts, and a pair of flow splitters for distributing the suction force applied to opposite ends of the vacuum stripper tube. The system is provided with a baffle disposed in the vacuum stripper tube for improving the distribution of suction force in the vacuum stripper tube. The system also includes an excess liquid collection arrangement constructed and arranged to establish a one-way flow of and collect excess liquid evacuated from the vacuum stripper tube. The system further contemplates a blow-off unit operably connected to the blower for supplying dry air to the hollow articles and conveyor belt.

Abstract: A simulation device is provided for testing autotrack antennas. The device includes a mode coupler and transmit horn which are identical to the mode coupler and transmit horn of the antenna to be tested. The mode coupler has a plurality of waveguide input ports for transmitting voltage signals which are complex conjugates of signals occurring under receiving conditions. The device then generates a signal that simulates the far-field, plane-wave testing environment and applies this signal to an antenna to be tested.

Abstract: A mobile petroleum processor or refinery. In particular a petroleum processor or refinery which has been constructed on railroad flatbed cars. The different units that make up the refinery are mounted on individual flat bed railroad cars and connected together. These cars can be moved over railroad networks to provide a petroleum refinery which can be moved in, set up, operated and taken down in a short time.

Abstract: A harness and belt assembly for a crewmember of an aircraft including left and right slings, a first belt assembly having first end second ends, a survival kit strap assembly attachment fitting which slidably engages the belt assembly, and a mechanism for releasably attaching the fitting to a seat of an aircraft. The slings are designed to extend from the chest of the crewmember, over the crewmember's shoulders, to the back of the crewmember. The first end of the belt assembly is attached to one of the slings at the portion designed to be adjacent the crewmember's chest. The second end of the belt assembly is attached to the other of the slings. A survival kit belt can be affixed to the fitting so that the survival kit ejects with the crewmember during an ejection.

Abstract: A self contained, self powered microprocessor controlled aircraft ejection seat escape parachute deployment sequencer which can handle problems caused by high altitudes into the stratosphere and by high speeds above Mach 1, and which will deploy the parachute, based on seat mounted pitot tube and ambient pressure readings plus stored data, when speed and altitude are at human physiologically acceptable levels. Many failsafes to cope with unusual conditions, and additional features are also included.

Abstract: A hinged container with a releasable closure for receiving a compressed down sleeping bag therein. The container comprises a pair of mating top and bottom members coupled at one end by a hinge; and the closure comprises a pair of bars which are rigidly coupled, respectively, to the top and bottom members and a pair of torsional shear bolts releasably coupling the bars together. These bolts are sheared by pivotal movement of two levers coupled thereto. The apparatus for compressing the sleeping bag into the container comprises an elongated, open-ended sleeve; a hydraulically-actuated compressing ram movable into and out of the sleeve; and an assembly at an end of the sleeve for releasably securing the container to the sleeve with an open end of the container aligned with the open end of the sleeve.

Abstract: An ejection seat is provided with fins on opposite sides which are normally stored along the seat side rails and are deployed immediately after ejection to yaw-stabilize the seat as it is slowed by a drogue. The fins are mounted for rotation and are deployed such that they extend rearwardly and out to the sides.

Abstract: A parachute deployment sequencer includes two sequencer systems in electromagnetic shielding housings. Each housing contains two bellows connected to pitot tubes, a third bellows for measuring ambient pressure and three switch contact sets connected in series, each contact set being operated by one of the bellows. Each housing also contains a battery actuated by seat ejection and a deployment firing circuit with a series switch circuit in between. After ejection, deployment is initiated when all three switches are closed.

Abstract: Various antenna systems are disclosed which generate a shaped beam having a substantially Gaussian distribution substantially without sidelobes. The antenna system consists of basic subarrays consisting of seven or nine radiating elements arranged respectively in a circle with a central element or in the form of a square. The radiating elements are fed in phase but the power applied to each element and the spacing is so selected that due to interference the sidelobes substantially disappear. More complex antenna arrays to form different beam shapes may be formed from the two basic subarrays.

Abstract: An ejection sequencing system used particularly in an ejection seat operation includes continuous sensing of both airspeed and altitude. The continuous airspeed sensing is accomplished by continuously measuring the airstream temperature and then determining the optimum instant for parachute deployment from the measured temperature, thus making the deployment event temperature-responsive. When the sensed airspeed is within a predetermined acceptable limits, a first signal is generated. Continuous altitude sensing is accomplished by an aneroid barometer and when the sensed altitude is within predetermined acceptable limits, a second signal is generated. When these first and second signals are transmitted to the parachute container, they initiate parachute deployment. Redundant, failsafe system operation can be provided through the use of two or more interconnected airspeed sensing devices having fixed time delays for backup.
