Abstract: A garment refreshing appliance comprising: an enclosure for receiving at least one garment to be refreshed, a support positioned in said enclosure to receive and suspend said garment in said enclosure, an air moving device arranged to circulate a flow of air within said enclosure, and an air duct associated with said air moving device to direct said circulating flow of air within said enclosure, said air duct having a plurality of flow directing vanes associated therewith to direct said recirculating flow of air against said garment.

Abstract: A wavelength division multiplexed self-healing passive optical network using a wavelength injection method includes a central office for coupling modulated multiplexed optical signals (MMOS) and broadband optical signals (BOS)for an upstream light source into one signal transmitted to a plurality of optical network units (ONUs) through a working main fiber and a protection main fiber. A remote node connects to the central office via the main fiber and protection main fiber and to the ONUs through working distribution fibers and protection distribution fibers. The remote node demultiplexes the MMOS and the (BOS) for an upstream light source. The remote node transmits demultiplexed signals to the ONUs, which receive the modulated optical signals and the BOS for an upstream light source which corresponds to predetermined ONUs, and demodulate the modulated optical signals, and modulate upstream optical signals via demultiplexed BOS for an upstream light source.

Abstract: Process for the preparation of urea from ammonia and carbon dioxide in which the composition of the various process streams is measured via an ultrasonic measuring principle and in which the results of these measurements are used for process control. The process is particularly suitable for continuous measurements in a urea process.

Abstract: The invention is a portable machine using two pairs of rollers to squeeze water from a wet floor mat. A motor provides a driving force to the lower rollers and the upper rollers are driven by frictional engagement with the lower rollers. After passing through the two sets of rollers, the mat exits the back of the machine and falls into a basket. After processing by the machine, the car mat is substantially dry and able to be placed into a car interior without fear of mold formation.

Abstract: An ink jet head which is -prevented from corrosion by ink, and an ink jet recording apparatus using the same. An ink-resistant thin film (25) made of Ti, a Ti compound, or Al2O3 is formed on the surface of recess portions (21 to 23) of a substrate in which a reservoir (8) for reserving ink, orifices (7) and pressure chambers (6) are formed. Since this ink-resistant thin film (25) is formed, corrosion can be restrained without reducing printing quality, without necessity to change the component/composition of the ink and the material of the head, and with little change of its manufacturing process, even if there is a fear that the head material may be corroded by the ink.

Abstract: A dense array of ink jets is achieved by a fanning-in of chambers to a linear array of orifices. The ends of the chambers remote from the orifices have actuation locations which are coupled to elongated transducers having axes of elongation which are parallel to the axes of ejection of droplets from the orifices.
