  • Water-dispersible urethane polymers, aqueous polymer dispersions and half-esters useful therein
    Patent number: 4329490
    Abstract: Aqueous dispersions of oil-modified, carboxyl-containing, urethane polymers are prepared by reacting diisocyanates or their isocyanate-terminated prepolymers, with half-esters of hindered diols, especially 2,2,4-trimethyl-1,3-pentanediol, and anhydrides of polycarboxylic acids, preferably aromatic acids having at least three carboxylic groups, especially trimellitic anhydride. The urethane polymers are "oil-modified", i.e., extended with unsaturated fatty acid esterpolyols; and when neutralized with ammonia or amines can be dispersed in water to form especially desirable coating compositions. An organic phosphite may be incorporated in the compositions to control the development of hardness in films made from the aqueous dispersions and thereby avoid the formation of wrinkles in films that are made from the compositions.

  • Polyurethane encapsulating resins
    Patent number: 4313858
    Abstract: A thermally-stable polyurethane encapsulating resin system which comprises a polyurethane prepolymer made by reacting a polyisocyanate with a polyol to form an isocyanate-terminated prepolymer. A second component of the system is a curing polyol for reacting with the prepolymer to form a polyurethane polymer having pendant vinyl groups provided by the use in said system of a hydroxy-terminated diene polymer. The system also contains a drying oil having an iodine number of up to about 200 in an amount sufficient to reduce the viscosity of the composition and improve filler loading. The system also contains a peroxide catalyst in an amount sufficient to promote cross-linking of the pendant vinyl groups of the intermediate polyurethane polymer to provide a thermally-stable polyurethane resin product, and promote the reaction of the drying oil into the product during curing.

  • Electrically controlled elevator
    Patent number: 4304375
    Abstract: A helicopter elevator (12, 13) is driven by an electrical actuator (20) to position the elevator (12, 13) to an optimum angle of incidence for given flight conditions. The actuator (20) is included within a servo loop which responds to a command signal derived from an electronics module (69). Transducers which measure longitudinal cyclic position (40), collective pitch position (41) and air speed (42) generate signals which are summed in a summation unit (43). The output of the summation unit (43) is passed through a signal multiplier (45) which has the gain thereof set inversely proportional to air speed. A trigger unit (56) activates the signal multiplier (45) at an air speed above a preset threshold. An integrator (54) integrates the sum of the outputs of the longitudinal cyclic position transducer (40) and air speed transducer (42) to compensate for different center of gravity aircraft loadings.

  • Airplane wing and undercarriage construction
    Patent number: 4298175
    Abstract: There is disclosed an airplane having an inflatable type air cushion confining undercarriage thereunder wherein the airplane wing structures comprise three-dimensionally enlarged inner wing components merging aerodynamically with the airplane fuselage. The under surfaces of the inner wing components and the fuselage cooperate to provide a downwardly convex broad base structure which is oval-shaped in planform, and a toroidal configured inflatable trunk is attached to the perimeter of the base structure for circumscribing the air cushion cavity under the airplane. Thus, an enlarged width and length air cushion type undercarriage is provided to give the airplane improved stability characteristics when operating in air cushion, ground, or water supported mode. When the trunk system is deflated the elastic sheet material thereof retracts snugly against the slightly convex bottom surface of the base structure.

  • Filament-type trimmer
    Patent number: 4287670
    Abstract: In a filament type trimmer in which a filament is wound on a storage spool rotatably mounted in a rotating housing having a rim portion, the filament in passing from the spool to an exit opening in the rim portion of the housing extends through a flexible tubular guide which wraps approximately one turn around the spool. The guide prevents the outer coils on the spool from becoming entangled and also prevents local melting and welding of the outer coils as the result of axial vibration in the string during operation of the trimmer.
