Filed: 1992-10-14
Abstract: The amount of N2O emission from a fluidized bed reactor is reduced by adding a hydrogen radical providing additive (e.g. a hydrogen containing fuel such as natural gas or alcohol) to the flue gases discharged from the fluidized bed. Sufficient oxygen is present in the flue gases-either by addition with the additive, or by addition of an excess to the combustion chamber-so that the additive reacts with the oxygen, typically raising the temperature of the flue gases (e.g. from about 700 DEG -900 DEG  C. to about 950 DEG -1100 DEG  C.) so that N2O production is reduced about 10-90%. The additive may be injected in or just prior to a cyclone for separating particles from the flue gases. In a gas discharge immediately after the cyclone, just prior to a superheater of a convection section, or in a combustion chamber just prior to a gas turbine.

Granted: 1996-04-02
Abstract: A separator tank for rainwater and waste-water includes a container defining an upwardly open chamber, with a lid to close the chamber.  An inlet is at a first location and an outlet is at a second location.  A passageway forms part of the container and communicates the inlet with the outlet.  A first opening is adjacent the inlet and communicates the passageway with the chamber, while a second opening is adjacent the outlet, also communicating the passageway with the chamber.  The passageway itself is sealed from communication with the chamber, except for the openings.  A weir is provided within the passageway, disposed with respect to the first opening such that, under relatively low entry flow rates, all entering materials are contained by the weir and flow through the first opening and into the chamber. Under relatively high entry flow rates, the entering materials overflow the weir and are delivered by the passageway to the outlet.

Abstract: A method of correcting or alleviating presbyopia in humans comprising (a) fitting a first contact lens to a first eye, and (b) fitting a second contact lens to the other eye. Each of the lenses has a first power provided by the shape, curvature and material of the lens to provide a refractive corrected image and a second power provided by diffractive means to provide a second corrected image, the second power being additive to (or subtracted from) the first power. the lenses are fitted so that one has a refractive near image optical power and the other has a refractive distance image optical power, and the diffractive means of the lenses are arranged so that the amount of the light directed into the near image by one lens is substantially greater than that directed into the far image by that lens, and the amount of light directed into the far image by the other lens is substantially greater than that directed into the near image by that other lens. In this way the wearer sees an image of relatively high intensity and retains a large amount of stereoscopic vision.

Title: Countergravity casting using particulate supported thin walled investment shell mold
Inventor: CHANDLEY GEORGE D
IPC: B22D18/06
Filed: 1991-08-15
Granted: 1996-10-15
Abstract: An expendable pattern of an article to be cast comprises a meltable material that expands upon heating (e.g., a wax pattern).  The pattern is invested with particulate mold material to form a thin, layered shell having a wall thickness not exceeding about .12 inch.  The thin shell wall thickness unexpectedly reduces damage and distortion to the shell during removal of the pattern therefrom by steam autoclaving.  After firing, the thin gas permeable shell mold is surrounded by a refractory particulate support media in a vacuum housing.  The vacuum housing is then evacuated to evacuate the mold cavity defined by the thin shell and concurrently a pressure is applied to the support media so as to compress the support media about the thin shell to support the shell against casting stresses when molten metal is countergravity cast into the evacuated mold cavity.

Granted: 1995-09-12
Abstract: A  cellular mobile  station  is  operable  in  a telephone mode and a time data display mode.  During the time display mode, the station constantly receives an area identifying  code  transmitted  from  a  cellular  mobile communications system.   On crossing a boundary between adjoining cell-site areas,  a time difference value  is entered  from  a  keypad  into  a  location  of  a  memory corresponding to the received code.   This  process  is continued on  a  learning basis  to  store  as many  time difference values into the memory as there are cell-site areas along the route of a journey.  Following the learning process,   the  station  constantly  receives  an  area identifying  code  and  recalls  one  of  the  stored  time difference data from the memory corresponding to a code received on crossing a boundary and modifies displayed timepiece data with the recalled time difference.
