Title: Dual combustion zone sulfur recovery process
Inventor: SZEKELY ANDREW GEZA
IPC: C01B17/04
Filed: 1991-01-28
Granted: 1997-01-21
Abstract: A sulfur recovery process wherein a minor fraction of a hydrogen sulfide-containing gas is precombusted with oxygen in an externally cooled combustion zone while extracting the major fraction of the heat released in the substantially complete combustion of hydrogen sulfide to sulfur dioxide in that zone, the gas is further cooled and is then passed to a Claus reaction furnace together with the major fraction of the gas, enabling using oxygen for a substantial productivity increase within the temperature and flow rate limitations of a Claus plant without need for a temperature moderator introduced into the precombustor.

Title: Drill grinding machine
Inventor: SCHROEDER RICHARD L
IPC: B24B3/30
Filed: 1991-04-15
Granted: 1993-11-30
Abstract: DRILL GRINDING MACHINE                 Abstract of the Disclosure A drill grinding machine employs independent servo motors for drill rotation, drill lift, and drill feed.  The three motors are connected through respective suitable drive mechanisms to a tubular spindle that is rotatably mounted within a work head.  The work head contains a hydraulic clamp for selectively chucking and releasing a drill holder.  A drill is gripped in the drill holder such that the drill point is proximate a grinding wheel.  The drill, lift, and feed motors are actuated to rotate the drill about its longitudinal axis and to move the drill point along a predetermined cyclical path of contact with the grinding wheel to grind a selected point.  Combinations of points may be ground on a single drill by suitably controlling the lift and feed motors.  A timing pad adjustably mounted to the machine housing cooperates with the lift and feed motors and the work head clamp to enable the drill to be manually timed prior to a grinding cycle.  Drill rock is selectively available through spring loaded contact between the work head and a hardened strip that is rotatably mounted in the machine housing.

Title: Lightweight metal with isolated pores and its production
Inventor: SANG HARRY
IPC: C22C1/10
Filed: 1991-07-11
Granted: 1997-02-25
Abstract: A novel lightweight gas-metal composite is produced having isolated particle-stabilized pores.  A composite of a metal matrix, e.g. aluminum, and finely divided solid stabilizer particles, e.g. silicon carbide, is heated above the liquidus temperature of the metal matrix and this is mixed such that a vortex is formed.  The molten composite is blanketed with a gas and during the vortex mixing.  This gas is drawn into the melt to produce an expanded, viscous molten composite material containing pores which are very small, spherical-shaped and quite evenly distributed.  The viscous molten composite material can be directly formed into a solid shaped product and is also capable of being remelted and formed by forming processes without destroying the integrity of the pores.  The result is a lightweight expanded metal product capable of being formed into shapes to close dimensional tolerances.
Patent CA-2051199-C (CA)
Title: Multiple input/output devices having shared address space
Inventor: D AMBROSE JOHN J
IPC: G06F13/10
Filed: 1991-09-11
Granted: 1996-03-05
Abstract: A   hardware-based   system   for   managing   multiple input/output devices sharing the same set of addresses in a computer system is described.  The new VIRTUAL ENABLED state is a hybrid of the current ENABLED or ACTIVE and DISABLED or INACTIVE  states.   In  the  ENABLED  state,  an  I/O  adapter responds to I/O addressing and presents interrupts to the processor.  In the DISABLED state, the I/O adapter does not respond to I/O addressing and does not present interrupts. In the new VIRTUAL ENABLED  state,  the  adapter does not respond to I/O addressing (as in the DISABLED state), but will still produce an interrupt (as in the ENABLED state). With the VIRTUAL state, multiple I/O adapters that would normally contend for the  same  set of addresses  (ENABLED state),  or  optionally  be  rendered  inoperable  (DISABLED state),  can  always  remain  available  for  I/O.   A  single register where the processor can read the interrupt status for all ENABLED and/or VIRTUAL ENABLED adapters sharing the same set of addresses is provided.  Other unique registers are also provided to allow the processor to cycle any of the ENABLED and VIRTUAL ENABLED devices between these two states to permit servicing of the interrupt.

Title: Apparatus and method for reducing harmonic interference generated by a clock signal
Inventor: CAHILL STEPHEN V
IPC: H03B1/04
Filed: 1992-10-20
Granted: 1997-12-09
Abstract: An apparatus and method therefor substantially reducing the interference of a harmonic frequency component (301) of a clock signal with a filtered received signal (302), comprises a frequency spreading signal generator (127) and a signal modulator (125). The frequency spreading signal generator (127) produces a frequency spreading signal (130). The signal modulator (125) modulates the clock signal, produced by a clock signal generator (129), with the frequency spreading signal (130) to produce a modulated clock signal (131) including a modulated harmonic frequency component (303). The power level of a modulated harmonic frequency component (303), corresponding to the harmonic frequency component interfering with the filtered signal (202-204), is spread over a frequency bandwidth (f6-f7) greater than the predetermined frequency bandwidth (f4-f5) causing the power level of the modulated harmonic frequency component (303) within the predetermined frequency bandwidth (f4-f5) to decrease.

Title: Nonwoven multicomponent polymer fabric and method for making same
Inventor: PIKE RICHARD DANIEL
IPC: D04H1/54
Filed: 1992-11-30
Granted: 2002-12-10
Abstract: A process for making nonwoven fabric including the steps of meltspinning continuous multicomponent polymeric filaments, drawing the multicomponent filaments, at least partially quenching the multicomponent filaments so that the multicomponents have latent helical crimp, activating the latent helical crimp, and thereafter, forming the crimped continuous multicomponent filaments into a first nonwoven fabric web. By crimping the filaments before the web formation, shrinkage of the web after formation is substantially reduced and the resulting fabric is substantially stable and uniform. In addition, the resulting fabric can have a relatively high loft. The crimp activating step can include heating the multicomponent filaments and preferably includes drawing the multicomponent filaments with a flow of heated air to activate the latent helical crimp.      The resulting fabric can form relatively high loft materials useful as a fluid management layer for personal care absorbent articles or can form cloth-like fabric useful as cover materials and garment material. In addition, a nonwoven fabric comprising continuous single and multicomponent filaments and proces for making same are provided. Still further, a multilayer nonwoven fabric with continuous multicomponent filaments and process for making same are provided. The degree of crimp in the filaments can be varied from layer to layer to produce composite webs with particular fluid handling properties.

Abstract: In producing a laminated packaging material comprising a base film, a silicon oxide layer and a sealant layer that are laminated together, the sealant layer is formed by laminating thermoplastic resin on the silicon oxide layer in thickness of less than 30 µm by using an extrusion coating method. At this time, in addition to the thermoplastic resin layer formed by extrusion coating method, thermoplastic resin film of another type may be laminated on the outside of the thermoplastic resin layer so that the two thermoplastic resin layers form the sealant layer. In this case, sandwich lamination is adopted in which thermoplastic resin is extruded into between the silicon oxide layer and the thermoplastic resin film in thickness of less than 30 µm. In addition, in a laminated packaging material for vertical pillow type packaging, consisting of a laminate of the sealant layer, the base film and the silicon oxide layer, a thermoplastic resin layer and an outer basic material are laminated on the outside of the silicon oxide layer simultaneously with the formation of the thermoplastic resin layer by extruding the thermoplastic resin between the outer basic material and the silicon oxide layer.
