Abstract: An H2S-containing feed gas is burned in at least one burner which opens into a combustion chamber, using oxygen and air. This gives a gas mixture containing H2S and SO2 to be converted into elemental sulphur by the Claus process. Oxygen is passed in through the central tube (13) of the burner, the H2S-containing feed gas is passed in through at least one second tube (14) which surrounds the central tube coaxially, and air is passed into the combustion chamber through a coaxial outer tube (15). The burner is charged with an H2S-containing feed gas whose hydrocarbon or CO2 content is at least 5 % by volume. At the orifice of the burner, the flow rate of the oxygen is 50 to 250 m/sec and that of the H2S-containing feed gas is 10 to 30 m/sec. In the core zone (18) of the burner flame, temperatures in the range from 2000 to 3000 DEG C are produced, and a gas mixture having temperatures of 1350 to 1650 DEG C and containing at least 2 % by volume of CO and at least 8 % by volume of H2 is discharged from the combustion chamber.

Inventor: OTTMAN TADD VAUGHN
IPC: G06F9/445
Filed: 1990-02-27
Granted: 2000-01-04
Abstract: The method of the present invention allows for the loading of operating systems between computers over a network, thereby drastically decreasing the amount of time required to download an operating system or update an operating system. A root directory is created and a subset of the operating system is loaded into the memory of the computer which is to receive the operating system, thereby eliminating the need to access or use the disk during the operating system download process. The subset of the operating system contains the basic commands for fife creation and manipulation, directory creation and network communication. The computer system is then started using the subset of the operating system located in memory and connected to the network. Once the computer is connected to the network, the files comprising the operating system to be downloaded are copied and transferred from a remote computer over the network and stored on the disk drive of the receiving computer.

Abstract: An improved die member and method of attaching a self-piercing and riveting fastener to a panel wherein a slug pierced from the panel by the riveting fastener is securely staked in the tubular riveting portion of the fastener during the installation of the fastener. The staking method includes shearing integral ribbons from the inside surface of the tubular barrel portion as the barrel portion is deformed radially outwardly in an annular die cavity of the die member. The integral ribbons are then preferably deformed radially inwardly in semicircular staking cavities defined through the free end of the central die poet. In the moat preferred method, radial tabs are simultaneously formed in the panel slug, which are deformed against an inside surface of the barrel portion, securely staking the slug in the tubular barrel portion and preventing inadvertent removal of the slug.

Title: Method of maintaining synchronization of a free-running secondary processor
Inventor: MCLAUGHLIN PAUL F
IPC: G05B19/05
Filed: 1991-09-18
Granted: 1998-05-26
Abstract: Data bases of a first and second input output processor (IOP), which are primary and secondary slave IOPs, respectively, are synchronized, and communications by a master controller is made only to the first IOP.     Each IOP is executing the same tasks utilizing their own clocking systems. A method for maintaining synchronization between the first and second IOP comprises the steps of transmitting a message addressed to the first IOP by the master controller.  The first IOP receives the message for subsequent execution.  Receipt of the message is acknowledged by a transmission back to the master controller the acknowledge message including a message number.  The second IOP eavesdrops on the transmissions between the master controller and any of the IOPs on the network.  Upon recognizing that the message is addressed to the corresponding first IOP and that the message is of a predetermined type, the second IOP receives the message for subsequent execution.  The second IOP verifies the message number in the acknowledge message, the message number being determinable by the second IOP, such that when both the first and second IOP complete execution of the received message which results in an update of the respective data bases, both data bases continue to contain the same information thereby maintaining synchronization.

Title: Image recording apparatus utilizing serial recording head and image recording method therefor
Inventor: TANAKA SOHEI
IPC: B41J11/42

Granted: 2000-11-14
Abstract: An image recording apparatus, having a recording head and a pair of transport rollers in front of the recording head and another pair of transport rollers behind the recording head, with a larger transport speed for a recording sheet in the latter pair for applying a suitable tension on the recording sheet, is capable of detecting the remaining amount of the sheet in front of the first pair and varying the transport speed and/or the recording area of the recording head after the rear end of the sheet leaves the first paired roller, in such a manner that the eventual error in record position, resulting from sheet advancement by the second paired rollers only, can be compensated.      In this manner the area of precise image recording on the sheet can be expanded.

Title: Alkaline leaching of galvanized steel scrap
Inventor: RODABAUGH RONALD D
IPC: C22B19/00
Filed: 1991-10-04
Granted: 1999-04-20
Abstract: Caustic dezincing galvanized steel scrap. A dezincing plant includes a plurality of tanks interconnected in series with steel scrap sequentially being moved through each of the tanks. The tanks contain a caustic leaching solution including an oxidant with the leaching solution being circulated through each of the tanks in a direction opposite to the movement of the scrap. Fresh scrap initially is exposed to a partially depleted leaching solution with the oxidant concentration of the leaching solution increasing as the scrap moves through the series of tanks. Leaching solution depleted of its oxidant is transferred to an electrolytic cell where zinc is removed and plated as metallic zinc powder onto a cathode. The leaching solution is recycled by removing zinc. The chemistry of the leaching solution is controlled so that sufficient free caustic is present to prevent passivating zinc coating on the scrap. Oxidant is added to the recycled solution and the caustic concentration is adjusted, if necessary, to have a total caustic concentration of at least 5 M and the recycled solution is returned to the last tank. Compressed scrap bales are dezinced and ready for use as a melting furnace charge material.

Patent CA-2060584-C (CA)
Title: Method and apparatus for controlling density profile in a concrete extruded slab
Inventor: MARTENS ERNST
IPC: B28B1/08
Filed: 1992-02-04
Granted: 1999-03-16
Abstract: In the extrusion of hollow core concrete slabs, the density profile across the slab is controlled by the vibration of a hammering plate forming one side of a packing chamber through which the concrete is extruded. Vibrations are imparted to the hammering plate by a vibrator that acts to produce vibratory motions in the plate that are not parallel to the direction of extrusion. With two vibrators producing vibratory components both in the direction of extrusion and outwardly to opposite sides of the packing chamber, the flow of concrete to the side edges of the slab is augmented. In an auger-type extruder, this allows the outer augers to be run at a slower speed than otherwise, thus increasing their service life. The vibratory frequency may also be reduced considerably, thus reducing the noise generated by operation of the apparatus.

Title: Fluid pulse generating apparatus
Inventor: STEINHARDT MICHAEL D
IPC: E03C1/06
Filed: 1992-11-06
Granted: 2002-04-16
Abstract: An apparatus for pulsing water flowing to a shower head includes a housing with a chamber, first and second water inlets to the chamber and a water outlet. The second inlet and the outlet are located through a wall of the housing at one end of the chamber. A valve has a plate with a plurality of apertures. The valve disposed within the chamber so that water flowing through the first inlet urges the valve into close proximity to the housing wall where rotational movement of the valve alternately opens and closes the water outlet.      That action creates a pulsed flow of water through the outlet.      Water flowing into the chamber through the second inlet moves the valve plate away from the housing wall permitting water to flow continuously from the second inlet into the outlet without being pulsed. A mechanism is coupled to the valve to produce the rotational movement.
