20100155515 | Safety accessory for coffee grinders-dispensers - A safety accessory for coffee grinders-dispensers includes a substantially cylindrical sleeve having a lower annular portion removably insertable into the base of a grinder-dispenser, an upper annular portion engagable with the neck of a container that contains coffee beans, and an intermediate annular portion provided internally with at least one interceptor member that allows the coffee beans to move into the grinding chamber but also prevents the insertion into the grinding chamber of an element in accordance with grinder-dispenser safety regulations. | 06-24-2010 |
20120228418 | Device for locking the micrometric grinding adjustment in coffee grinders - A device for locking the micrometric adjustment of the degree of grinding in coffee grinders includes a hollow cylindrical casing for housing a lower grinding wheel carrier, which is connected to a motion transmission shaft, and for housing an upper grinding wheel carrier, which is axially movable; and a threaded ring nut engagable in the casing to adjust the position of the upper grinding wheel carrier, wherein the ring nut has at least one seat for inserting a peg for locking its rotation, and the casing has an undercut slot in which a slider cooperating with the peg is housed, the thickness of the slider being less than the thickness of the slot. A member engages the slider and causes it to rise and to interfere by friction with the upper wall of the slot. | 09-13-2012 |

20100011975 | Coffee grinder-dispenser with cooling fans - A coffee grinder-dispenser comprising a base housing an electric motor, with a vertically extending rotatable shaft which is connected to a grinder located in a grinding chamber. A vessel located above the grinding chamber receives coffee beans to be ground. A closure plate allows the coffee beans to enter the grinding chamber. A conduit allows the coffee, after grinding, to be delivered to a funnel; the ground coffee passes downwardly through the funnel into a filter holder. One cooling fan faces the grinding chamber, is activated by a keypad on the funnel, and delivers air transversely across the interior of the housing. A second cooling fan is located on the vertical shaft of the electric motor. The fans are operated by a controller, located within the housing, and provide sufficient cooling air to the grinding chamber to maintain the desired qualities of taste and aroma in the ground coffee. | 01-21-2010 |

20090277494 | SOLAR CONCENTRATORS - Light collectors for use in building-integrated solar concentrators comprise waveguiding components incorporating spaced-apart light collecting elements arranged to collect light from a plurality of lenses in a lens array and deliver light to solar cells for photovoltaic conversion, where several lenses are coupled to each individual solar cell. The light collecting elements may comprise shaped ends of bulk waveguides to deliver incident solar radiation directly to the solar cells, or luminescent or amplifying material that converts the incident radiation to a secondary light signal that is delivered to the cells. The lenses may be pivotally mounted in a variety of ways to improve solar tracking by avoiding mechanical clashes between lenses and optimising the amount of incident light that is harvested. Filters containing heavy water may be positioned in front of the solar cells to absorb long wavelength light unconvertible by the cells, heat energy being then extractable from the heavy water. | 11-12-2009 |

20080230112 | Photovoltaic cells - A photovoltaic system includes a photovoltaic device that includes a lower photovoltaic cell fabricated from semiconductor material having a first bandgap, and having first electrical contacts for extraction of current from the lower cell; an electrically insulating layer monolithically fabricated on the lower photovoltaic cell; and an upper photovoltaic cell monolithically fabricated on the electrically insulating layer from semiconductor material having a second bandgap larger than the first bandgap, and having second electrical contacts for extraction of current from the upper cell. The photovoltaic system also includes one or more first photon sources operable to supply photons to the photovoltaic device, the photons having wavelengths in a first wavelength range associated primarily with the first bandgap. The photovoltaic system further includes one or more second photon sources operable to supply photons to the photovoltaic device, the photons having wavelengths in a second wavelength range primarily associated with the second bandgap. | 09-25-2008 |
20080251118 | Photovoltaic device - A method of forming a photovoltaic device includes a plurality of quantum wells and a plurality of barriers. The quantum wells and barriers are disposed on an underlying layer. The barriers alternate with the quantum wells. One of the plurality of quantum wells and the plurality of barriers is comprised of tensile strained layers and the other of the plurality of quantum wells and the plurality of barriers is comprised of compressively strained layers. The tensile and compressively strained layers have elastic properties. The method includes selecting compositions and thicknesses of the barriers and quantum wells taking into account the elastic properties such that each period of one tensile strained layer and one compressively strained layer exerts substantially no shear force on a neighboring structure; providing the underlying layer; and forming the quantum sells and barriers on the underlying layer according to the derived compositions and thicknesses. | 10-16-2008 |
20130269760 | PHOTOVOLTAIC JUNCTION FOR A SOLAR CELL - A photovoltaic junction for a solar cell is provided. The photovoltaic junction has an intrinsic region comprising a multiple quantum well stack formed from a series of quantum wells separated by barriers, in which the tensile stress in some of the quantum wells is partly or completely balanced by compressive stress in the others of the quantum wells. The overall elastostatic equilibrium of the multiple quantum well stack may be ensured by engineering the structural and optical properties of the quantum wells only, with the barriers having the same lattice constant as the materials used in the oppositely doped semiconductor regions of the junction, or equivalently as the actual lattice size of the junction or intrinsic region, or the bulk or effective lattice size of the substrate. Alternatively, the barriers may contribute to the stress balance. | 10-17-2013 |
