Patent number: 5121188Abstract: A self-contained laser module assembly has a diode laser and driver circuit enclosed with a cylindrical metal housing which forms a first electrical contact for inputting a DC voltage to power the circuit and laser. The housing has a first end which includes a lens positioned to emit a collimated laser beam along an axis of the housing and a second end including a second external electrical contact positioned to contact the power supply. One application of the module is in a pen-like pointer. The pointer includes conductive cap and body portions which are threaded together to house a laser module and a battery in end-to-end relationship. An O-ring between the battery and the body or module is axially compressed by tightening the cap on the body to enable turning on the pointer. The cap has a pocket clip through which electrical contact is selectably made between the body and a side contact on the module to cause a beam to be emitted.Type: GrantFiled: May 16, 1990Date of Patent: June 9, 1992Assignee: Applied Laser SystemsInventors: William C.

Patent number: 4889699Abstract: Synthesis gas is produced by the partial oxidation of a feedstock comprising sulfur and ash-containing heavy liquid hydrocarbonaceous fuels, solid carbonaceous fuels, or mixtures thereof. An iron-containing additive is introduced into the reaction zone along with the feed to produce first and second liquid phase washing agents that collect and transport the vanadium-containing oxide laths and spinels and other ash components out of the reaction zone. A gaseous slag fludizing agent is also introduced into the top of the reaction zone so tha the gasifier is operated at a uniform temperature throughout under conditions that maximize the fluidity of the molten slag over the full opereating temperature range in the gasifier. Equilibrium oxygen and sulfur concentrations are provided in the gas phase in the reaction zone which provide specific partial pressures.Type: GrantFiled: June 20, 1988Date of Patent: December 26, 1989Assignee: Texaco Inc.Inventors: Mitri S.

Patent number: 4828579Abstract: Reactor for gasifying a carbonaceous fuel to produce a usable gas, and comprising an insulated outer shell. A reaction chamber within the shell receives a fuel mixture from an injection burner. The products or effluent of gasification include hot produced gases which are passed through a constricted throat to be cooled in a liquid bath. A dip tube, which guides the hot effluent into the bath, is provided with a stream of coolant from a quench ring. The latter is supported below the reaction chamber and is provided with a thermal barrier along its surface that is exposed to the hot produced gas. The barrier will reduce thermal stress in the quench ring and reduce drain of heat from the gasifier throat, thus avoiding premature chilling of the slag component.Type: GrantFiled: March 7, 1988Date of Patent: May 9, 1989Inventors: Michael W. Becker, Allen M. Robin, John S. Stevenson

Patent number: 4803061Abstract: Synthesis gas is produced by the partial oxidation of a feedstock comprising petroleum coke and/or heavy liquid hydrocarbon fuel containing sulfur and having an ash that contains nickel, vanadium and silicon. An iron-containing or an iron and calcium-containing additive is introduced into the reaction zone along with the feed. The additive combines with at least a portion of the iron and nickel constituents and sulfur found in the feedstock to produce a liquid phase washing agent that collects and transports at least a portion of the vanadium-containing oxide laths and spinels and other ash components out the reaction zone. Slag and other particulate matter is separated from the effluent gas stream and ground to produce a heterogeneous mixture of magnetic and non-magnetic solid particles.Type: GrantFiled: December 29, 1986Date of Patent: February 7, 1989Assignee: Texaco Inc.Inventors: Mitri S.

Patent number: 4788003Abstract: This invention pertains to the use of an ash-removal additive in the production of hot raw gaseous mixtures comprising H.sub.2 +CO and containing entrained molten slag by the partial oxidation of a feedstock comprising a heavy liquid hydrocarbonaceous fuel having a nickel and vanadium-containing ash or petroleum coke having a nickel and vanadium-containing ash. Sticking and build-up of molten slag on the surfaces of a steel quench ring and heat exchanger which may be contacted by the molten slag entrained in the hot raw effluent gas stream is prevented by the high temperature electrodeposition of a protective metal e.g. aluminum or titanium. The protective metal is electrodeposited from an electrolytic bath comprising molten fluorides and diffuses beneath the surface and forms an alloy or solid solution with the subsurface metal.Type: GrantFiled: May 4, 1987Date of Patent: November 29, 1988Assignee: Texaco Inc.Inventors: Mitri S.
