摘要:
The present invention is a power meter with auto switching control. It comprises a power measurement unit where the power and energy data can be display either locally as well as remotely through wireless communications, an electrical receptacle, plug or strip connecting power to electrically powered equipment or devices; a switch with open and close states to control power off and on; a combination of buttons for manual controls and settings; embedded or externally connected sensors to provide signal input, for example but not limited to, occupancy sensors and infrared sensors; a processing unit to automatically control the power on/off according to the measured power, sensor signals, user input, schedules and control strategies; and storage units to hold these control strategies and algorithms and save data.

A process for the production of a metal which comprises: carbothermal reduction of the corresponding metal oxide to produce a mixed gas stream comprising the metal and carbon monoxide; maintaining the mixed gas stream at a suitably elevated temperature to prevent reformation of the metal oxide; ejecting the mixed gas stream through a convergent-divergent nozzle in order to cool the mixed gas stream instantaneously to a temperature at which reformation of the metal oxide cannot take place; and separating and collecting the metal, wherein the nozzle is heated by means other than gas flow through the nozzle so that temperature of surfaces of the nozzle in contact with the mixed gas stream are maintained at a temperature sufficient to prevent deposition on the said surfaces of products from the gas stream.

A neck for a string instrument is provided with a shape that varies along the length of the neck to facilitate an appropriate hand posture at various longitudinal positions on the neck. The neck has a heel end for receiving a body of a string instrument, a head end relative to the heel end, and a fingerboard surface. Adjacent the fingerboard surface, the bass side of the neck is chamfered, relative to the treble side of the neck, from an intermediate position between the heel end and the head end of the neck toward the heel end of the neck, for accommodating a user's thumb when fretting in an upper register portion of the neck.

摘要:
Tissue sheets are disclosed containing an additive composition. The additive composition is applied to the tissue sheet during a creping process in a controlled manner such that the additive composition forms deposits on the sheet separated by untreated areas. In one embodiment, the additive composition is applied to a creping surface. A wet tissue sheet is then transferred to the creping surface by a topographical surface containing elevations. The elevations press the tissue sheet against the creping surface. When creped from the surface, the additive compositions transfers to the tissue sheet according to where the elevations were located on the topographical surface.
