International Classification:

US Classification:

359227, 1601661, 160236, 156349

Abstract:

A method of making a fabric Venetian blind comprises helical winding of a narrow, elongated strip, which, when properly overlapped and bonded along longitudinal glue lines, will form the vanes and front and rear facings of the blind. The strips may be formed of a single, uniform material, or of adjacent, longitudinally extending portions of relatively opaque and relatively translucent fabric. An alternative embodiment uses the same winding technique to similarly form a structure of only translucent fabric, but with pockets for subsequent insertion of opaque vanes. Several alternative strip configurations and assembly arrangements are disclosed. The disclosed method and structure may also be used to form products for other applications.

Abstract:

A hybrid high-temperature solar receiver is provided which comprises a solar heat-pipe-receiver including a front dome having a solar absorber surface for receiving concentrated solar energy, a heat pipe wick, a rear dome, a sidewall joining the front and the rear dome, and a vapor and a return liquid tube connecting to an engine, and a fossil fuel fired combustion system in radial integration with the sidewall for simultaneous operation with the solar heat pipe receiver, the combustion system comprising an air and fuel pre-mixer, an outer cooling jacket for tangentially introducing and cooling the mixture, a recuperator for preheating the mixture, a burner plenum having an inner and an outer wall, a porous cylindrical metal matrix burner firing radially inward facing a sodium vapor sink, the mixture ignited downstream of the matrix forming combustion products, an exhaust plenum, a fossil-fuel heat-input surface having an outer surface covered with a pin-fin array, the combustion products flowing through the array to give up additional heat to the receiver, and an inner surface covered with an extension of the heat-pipe wick, a pin-fin shroud sealed to the burner and exhaust plenums, an end seal, a flue-gas diversion tube and a flue-gas valve for use at off-design conditions to limit the temperature of the pre-heated air and fuel mixture, preventing pre-ignition.

International Classification:

US Classification:

60520, 123 46 R

Abstract:

A free-piston device has a stabilized piston drift. A piston having a frequency of reciprocation over a stroke length and with first and second sides facing first and second variable volumes, respectively, for containing a working fluid defining an acoustic wavelength at the frequency of reciprocation. A bypass tube waveguide connects the first and second variable volumes at all times during reciprocation of the piston. The waveguide has a relatively low impedance for steady flow and a relatively high impedance for oscillating flow at the frequency of reciprocation of the piston, so that steady flow returns fluid leakage from about the piston between the first and second volumes while oscillating flow is not diverted through the waveguide. Thus, net leakage about the piston is returned during each stroke of the piston while oscillating leakage is not allowed and pressure buildup on either the first or second side of the piston is avoided to provide a stable piston location.

Inventors:

Assignee:

Clever Fellows Innovation Consortium, Inc. - Troy NY

International Classification:

F25B 900

US Classification:

62 6

Abstract:

A mechanical resonator for a thermoacoustic device having a compressible fluid contained within a housing, the housing having a pair of heat exchangers and a thermodynamic medium therebetween. The resonator includes a member for mimicking dynamic conditions at a position of the housing; and a linear suspension element suspending the member in the housing. The mechanical resonator saves length and eliminates high-velocity flow losses. A transducer may also be mounted with the mechanical resonator to derive power in another form from the system, for example, electricity, or introduce power into the system. In combination, the transducer and mechanical resonator allow for cool-side driving of a thermoacoustic system.

International Classification:

Abstract:

A method for matching an acoustic load and an acoustic driver in a resonant acoustic system, and the acoustic system so formed. The load and driver may be independently designed. The invention provides, inter alia, a matching volume positioned between the acoustic driver and load that is substantially greater than a stroke volume of the driver. The matching volume is sized such that, in combination with the moving mass, the characteristic stiffness of the acoustic driver and the characteristic load impedance, a resulting pressure wave produces an operating resonant frequency substantially equal to the preferred operating frequency of the load. Alternatively, or in addition thereto, a stroke volume of the acoustic driver can be adjusted.
