Abstract:
A hydraulic assisted turbocharger (18) provides charge air to the intake manifold (14) of a vehicle internal combustion engine (12). The hydraulic assist (54) can be selectively turned on by the vehicle operator when the vehicle is stopped or is travelling at a low speed so that charge air can be supplied to the engine (12) immediately upon a subsequent acceleration.
Abstract:
The present invention provides a composition comprising; (a) 1,1-dichloro-2,2,2-trifluoroethane; (b) a hydrogen-contributing compound; and (c) a sufficient amount of a compound which substantially reduces the formation of 1-chloro-2,2,2-trifluoroethane. The present composition is useful in compression refrigeration and air-conditioning equipment.
Abstract:
A filter/conditioner for filtering and dispensing conditioners and inhibitors to the engine coolant of an internal combustion engine includes a circumferentially extending array of filtering media circumscribing a container defining a compartment which contains a coolant softener/conditioner and a rust inhibitor pellet which dissolves to release rust inhibitor into the coolant. A diamond design is embossed on the outer circumferential surface of the container, so that grooves provided to permit coolant to travel to one of the ends of the container, and then through the container where the coolant is treated.
Abstract:
A sinter-reactive lanthanum chromite powder is prepared from the lanthanum chromite precursor LaCr1-xMxO3 (Adsorbate). The powder is crystalline, has the formula LaCr1-xMxO3, where M is magnesium or calcium and x ranges from about 0.03 to 0.3, and sinters to densities higher than about 95 % of theoretical density at temperature as low as 1600 DEG C in inert or reducing atmospheres. Sintering to such high density at temperatures in the vicinity of 1600 DEG C makes the powder particularly suited for use as interconnect material for solid oxide fuel cells.
Abstract:
A method and correction circuit is described incorporating a monopulse receiver (30), injecting a first signal of known amplitude and arbitrary phase and a second signal of the same amplitude shifted 90° and measuring the output voltages of the channel and using the measurements to generate four coefficients which may be mathematically applied to the output signals of the channel to provide a corrected output (71, 72, 71', 72'). The invention overcomes the problem of compensating for phase and gain drift in the in-phase and quadrature paths of the sum and difference channels of a monopulse receiver.
Abstract:
A method of spinning discontinuous lengths (staple) of a high molecular weight (over 150,000) polyethylene fiber, and the resulting spun fiber, are disclosed. The method comprises blending a sufficient amount of discontinuous lengths of any other fiber (as a carrier) with the high molecular weight polyethylene fiber lengths to permit spinning. The resulting spun yarn preferably comprises about 5 to 95 weight percent discontinuous lengths of the high molecular weight polyethylene fiber which is characterized by a denier per filament of 20 or under and an ultimate elongation of 8 % or under at room temperature, and about 5 to 95 weight percent discontinuous lengths of the other fiber which is characterized by a denier per filament of 20 or under and which is either permanently crimped or has a memory. The carrier fiber or mixtures of carrier fibers may be chosen to achieve specific properties in the spun fiber: e.g., polyester or cotton for hand; pigmented polypropylene for color; aramids and polybenzimidazoles (PBI) for flame resistance; and carbon for chemical absorbance or resistance and for use in composites requiring strength and toughness. The spun fiber has utility in composites, industrial, medical and/or apparel applications.
Abstract:
An optic system (10) having a lens arrangement (38) for collimating a beam of light carried by a first array (20) of a bifurcated fiber bundle (18) to uniformly illuminate the entire surface (36) of a fluorescent material (30) to create an output signal corresponding to the temperature of the fluorescent material (30). The lens arrangement (38) focuses the output signal onto the end (34) of bifurcated fiber bundle (18) where a second array (24) communicates up to one half of the output signal generated by the glow of the fluorescent material (30) to a detector (44) which processes the output signal to inform an operator of the temperature of the fluorescent material (30).
Abstract:
A system for conditioning working fluid in environmental control systems (10, 310) includes arrangements for minimizing icing from a variable flow velocity turbine exit flow (88) at subfreezing conditions, wherein the turbine (22) is very closely located to the downstream heat exchanger (14), including a backpressure plate (246) for minimizing flow velocity stratification, an internal bypass passage (254) arranged to produce a relatively predictable bypass flow ratio regardless of the flow velocity stratification, and other anti-icing techniques (232, 260, 346, 454).
Abstract:
A magnetic metallic glass alloy exhibits, in combination, high saturation induction and low magnetic anisotropy energy. The alloy has a composition described by the formula FeaCobBcSidCe, where "a" - "e" are in atom percent, "a" ranges from about 72 to about 84, "b" ranges from about 2 to about 8, "c" ranges from about 11 to about 16, "d" ranges from about 1 to about 4, and "e" is zero or ranges from about 3 to about 4, with up to about 1 atom percent of Mn being optionally present in the alloy, with the provisos that (i) when "e" is zero and "a" is greater than or equal to 80, "b" cannot exceed 4, (ii) when "e" is zero and "a" is less than 80 by an amount x, "b" cannot exceed (4+4x) and, (iii) the sum ("a"+"b"+"c"+"d"+"e") equals 100. Such an alloy is especially suited for use in large magnetic cores associated with pulse power applications requiring high magnetization rates. Examples of such applications include high power pulse sources for linear induction particle accelerators, induction modules for coupling energy from the pulse source to the beam of these accelerators, magnetic switches in power generators in inertial confinement fusion research, magnetic modulators for driving excimer lasers, and the like.
