Abstract: ABSTRACT OF THE DISCLOSURE          Disclosed herein is a carburetor for internal combustion engines having an automatic choke control mechanism including a vacuum diaphragm assembly operatively connected to a choke lever for opening a spring-biased closed choke valve and holding it open at idling and lower engine speeds and a linkage arrangement interconnecting a throttle valve lever and the choke lever for holding the choke valve open at higher engine speeds independently of the vacuum diaphragm assembly.  The linkage arrangement includes a spring-biased choke pull-out lever which is held in a locked position during engine idling and lower engine speeds by a link having one end slidably received in a slot in the choke pull-out lever and the other end connected to the throttle lever.  As the throttle lever is moved past a predetermined advance speed position, the link is moved to a released position in the choke pull-out lever slot wherein the choke pull-out lever is urged into abutting engagement with the choke lever to hold the choke valve open.  As the throttle lever is returned toward the engine idling position past the predetermined advance speed setting, the link returns the choke pull-out lever to the locked position and the choke lever is again controlled by the vacuum diaphragm assembly.

Abstract: ABSTRACT OF THE DISCLOSURE    A large motion expansion joint having a plurality of load-carrying modules which are positioned in parallel relationship to each other and aligned in a direction  trans-verse to the direction of the roadway.  The load-carrying modules generally span the expansion gap between adjacent structural members to support vehicular traffic thereon and include a first end module mounted to an edge of one of the structural members, a second end module mounted to an edge of an adjacent structural member and at least one intermediate module spaced between the first and second end modules.  The intermediate modules carry beneath its upper surface a plur-ality of spaced sleeve-like beam guides which are aligned with a plurality of spaced elongated sleeve-like support beam hous-ings fixedly secured to the second end module.  A plurality of support beams are fixed to the first end module and slide into the beam guides and housings generally in the direction of the roadway so as to support the load-carrying modules. During expansion and contraction of the structural members, the load-carrying modules slide upon the support beams and move toward and away from each other as the gap is either narrowed or widened.  The spacing between modules is  proportionally main-tained during expansion and contraction by means of a linkage system which includes at least two sets of linkages intercon-necting each adjacent pair of load-carrying modules with the linkages arranged generally in a zig-zag configuration gen-erally along the direction of the roadway.  Some of the linkages have bifurcated forked ends and some of the linkages have tongue-shaped blade-like ends with the bifurcated forked ends of the linkages on each module pivotally connected to the tongue-shaped blade-like end of the linkages on adjoining modules Pads are mounted upon the load-carrying modules to provide a roadway surface across the gap.  The space between each module is covered and protected by resiliently yieldable sealing mem-branes secured at the top surfaces of the load-carrying modules and against the underside of the pads with the sealing mem-branes overlying the linkages to prevent water, dirt and other debris from passing downwardly between the modules.

Abstract: ABSTRACT         A motor control apparatus is disclosed having an electric motor which is driven in one direction by an alter-nating current power source and in a return direction by a spring return wherein a holding or braking of the motor is accomplished by the application of direct current to magnetize the motor and hold it in a predetermined intermediate position after the removal of the alternating current power source.  The level of direct current supplied to the motor for braking or holding is held low enough to allow the return spring to mechan-ically demagnetize or degauss the motor so that it will return to its initial position; i.e. the residual magnetism of the motor is kept small enough that the return spring can return the motor to its initial position.  The motor control apparatus is partic-ularly adapted for use to control a three position water valve supplying water to one or both of two different areas or zones as required by area or zone thermostats.

Abstract: Abstract A propulsion system for use primarily in V/STOL aircraft is provided with a variable cycle, double bypass gas turbofan engine and a remote augmenter to produce auxiliary lift. the fan is oversized in air-pumping capa-bility with respect to the cruise flight requirements of the remainder of the engine and a variable area, low pressure turbine is capable of supplying vary-ing amounts of rotational energy to the oversized fan, thereby modulating its speed and pumping capability. During powered lift flight, the variable cycle engine is operated in the single bypass mode with the oversized fan at its maxi-mum pumping capability. In this mode, substantially all of the bypass flow is routed as an auxiliary airstream to the remote augmenter where it is mixed with fuel, burned and exhausted through a vectorable nozzle to produce thrust for lifting. Additional lift is generated by the high energy products of combus-tion of the variable cycle engine which are further energized in an afterburner and exhausted through a thrust vectorable nozzle at the rear or the engine. In the cruise operating mode, the fan is driven at a slower notational speed and all of the bypass flow is directed to a variable area bypass injector where it is mixed with the variable cycle engine products of combustion and exhausted as a mixture through the rear nozzle.  The variable cycle engine can be selectively operated in the single or double bypass mode during cruise to maximize effi-ciency as the aircraft speed is varied.  Because the total Installed thrust is available in the forward cruise mode, an aircraft powered by the propulsion system of the present invention has substantially greater capabilities in the areas of excess power, acceleration time and combat ceiling when compared to prior art conceptions embodying separate lift plus lift/cruise engine. Additionally, by not having to develop and maintain a separate lift engine system, a substantially lower aircraft life cycle cost is possible.

Abstract: 51628(U) ABSTRACT OF THE DISCLOSURE      Structural honeycomb material is expanded to open hexagonally cellular state, by pulling it out in the expan? direction.  It is then compressed across the expansion dir ? tion and fed through a throat where it undergoes further compression which creases the constituent material.  On being allowed to re-expand, the material adopts a stable open-cellular state.          The feeding of the material through the throat is accomplished by driving means which engages the material across the expansion direction.  This is an improvement on feeding it between driving rollers having rotational axes parallel with the major axes of the cells.  Satisfactory compression in the throat is more easily obtained, especially with small cell-sizes.     SPECIFICATION OF THE INVENTION

Abstract: ABSTRACT OF THE DISCLOSURE:             A diaper comprises an outer sheet of waterproof plastic material having a deformed recess area between the sides and ends thereof which forms a pad receiving cavity which is bordered by marginal areas on each side and end.  The cavity is about an inch deep and includes a bottom which is advantageously provided with corrugations or pleats which facilitate its ex-pansion or distortion during wearing.  An absorbent pad is disposed in the cavity, and a moisture holding strip of plastic material overlies at least a part of the marginal area on each side of the cavity and at least a portion of each side of the pad.  The strip is welded to the marginal areas, and as a feature of the construction the plastic is stretched relative to the outer sheet and held in a stretched condition during welding so as to impart some resilient characteristics to the area which is adapted to engaged around the legs of the wearer.  Because the strip overlies the cavity, it aids in securing the pad in position and what is more, it insures that any liquid such as urine which may collect in the pad will not run out of the cavity.
