Title: Method of regulating the superheating temperature of steam in a circulating fluidized bed type gas cooler
Inventor: ARPALAHTI OLLI
IPC: F28D13/00
Filed: 1995-11-14
Abstract: The present invention refers to a method of regulating the steam superheating temperature in a circulating fluidized bed type gas cooler. Hot gas is introduced into a mixing chamber, where it is mixed with solids having a temperature lower than that of the gas, whereby the temperature of the mixing chamber settles to a mixing temperature. The mixture of the gas and solids is taken from the mixing chamber via a riser to a solids separator, heat being thereby cooling the mixture of gas and solids and transferring heat to heat transfer surfaces. Solids are separated from the gas in the separator and recirculated into the mixing chamber. In connection with the cooling of the gas, superheated steam is generated in evaporators and superheaters arranged in the cooler. The mixing temperature in the mixing chamber, according to the invention, is utilized for temperature regulation of the superheated steam generated in connection with the gas cooling. The mixing temperature may be regulated by controlling the amount and temperature of solid material being introduced into the mixing chamber.

Abstract: A method of forming an optical element on the surface of a substrate by ejecting a curable microlens  forming  liquid  from a  nozzle  onto the surface  of  the  substrate  and  curing  the  curable microlens forming liquid. The nozzle tip is parallel to the surface of the substrate when the nozzle tip is moved away from the substrate. Anamorphic lenses may be formed by moving the nozzle tip immediately after ejecting liquid onto the surface of the substrate. F/numbers of lenses in an array are made more uniform by allowing the lenses to settle while in liquid form before curing. F/number of lenses may be controlled by controlling the surface tension of the surface of the substrate.

Title: One-trip well perforation/proppant fracturing apparatus and methods
Inventor: JACKSON ALAN T
IPC: E21B43/267
Filed: 1998-01-30
Abstract: In a subterranean well a one-trip production zone perforation and proppant fracturing operation is carried out using a workstring-supported perforation gun lowered into a casing nipple located in the production zone. Firing of the gun creates spaced apart aligned sets of perforations extending outwardly through a side wall portion of the workstring, the nipple, the surrounding cement, and into the production zone, after which the gun falls intoand is retained in an underlying gun catcher portion of the workstring. While an overpull force is maintained on the workstring above the perforations, a proppant slurry is pumped down the workstring, out its sidewall perforations, and outwardly through the aligned perforation sets formed in the nipple, cement and production zone. After stimulation of the production zone, the workstring and the spent perforation gun that it retains are pulled up, with theupwardly moving workstring positioning a sliding closure device inwardly over the perforations to isolate the stimulated production zone until the well is readied for production. Illustrated alternate embodiments include the use of a low debris casing gun in place of the drop-off type perforating gun, the use of pre-formed wide wall perforations in the workstring side wall, and a one-trip perforation and production flow creating method in which the production zone stimulating step is eliminated.

IPC: B60T17/22
Filed: 1998-05-04
Abstract: A system reliably communicates brake commands from a master controller on a lead locomotive to the brake equipment on each rail vehicle of a freight train. The system includes a mechanism for detecting whether the brake commands are being successfully communicated over a communications channel that is normally used to convey such commands from the master controller to the brake equipment on each rail vehicle. The system also includes on each rail vehicle a mechanism for communicating the brake commands that is independent of the communications channel. The mechanism for communicating conveys the brake commands from the lead locomotive to the rail vehicles only when the mechanism for detecting determines that communication over the communications channel has failed. The system further includes on each rail vehicle a mechanism for receiving the brake commands from the lead locomotive via the mechanism for communicating. The system additionally includes on each rail vehicle a mechanism for acting upon the brake commands received from the mechanism for receiving so that the brake equipment can execute the brake commands as if they were conveyed to the brake equipment over the communications channel.
