Title: Method and apparatus for treating contaminated soil
Inventor: BARCELL ROBERT B
IPC: B09C1/06
Filed: 1990-11-29
Abstract: A vehicle-mounted system for removing hydrocarbon contaminants from the soil has an inclined rotary kiln (10) which is rotated about a substantially horizontal axis of rotation, a burner assembly (18) at the discharge end of the kiln and a hopper (11) for loading soil into the inlet end to advance through the kiln and be directly heated by the burner assembly. The exhaust stream created in the kiln is drawn through a baghouse (24) for removal of fines, then through a catalytic incinerator (32) to burn any unburned constituents in the exhaust stream. The temperature of the exhaust stream is monitored prior to its passage into the incinerator and at the discharge end of the incinerator as well; and the concentration of hydrocarbon constituents in the exhaust stream is regulated either by introduction of air into the exhaust stream as it is discharged from the kiln or by recirculating a portion of the exhaust stream, after filtration, into the kiln.

Title: Pulse analysis system and method
Inventor: LABARRE GARY K
IPC: G01R29/02
Filed: 1991-09-03
Abstract: 55,890 ABSTRACT OF THE DISCLOSURE The invention is a system and method that uses a digital oscilloscope to digitize a waveform and then loads the digitized waveform into a computer.  The computer scans the waveform data locating leading edges by comparing data to a rolling average and a noise threshold and locating tops bottoms if the pulse is negative going of pulses by comparing data to slope criteria until a trailing edge is discovered.  The trailing edge defines the end of the pulse, the immediately preceding leading edge defines the beginning of the pulse and the pulse height and this allows the pulse characteristics to be determined.  This discovered pulse is removed from the waveform by setting all data values in the pulse to the pulse baseline value, and the scan for leading edges, pulse tops and a trailing edge is performed again to isolate and characterize another pulse.  This cycle of detection, analysis and removal continues until the end of data is encountered before a pulse is discovered.1

Title: Band with slotted wedge cams
Inventor: GUNDY WILLIAM P
IPC: F16L33/02
Filed: 1991-10-08
Abstract: A band assembly for effecting a seal particularly adapted for use in establishing a saint between a sewer pipe and a reinforced concrete manhole riser. The seal is affected by a tapered elastomeric tubular connector boot and a clamping band member kith an expansion mechanism. Wedge followers are loosely captured in the end sections of the clamping band and lie glens a circumferential center line on the band. Driving wedges extend along an axis transverse to the circumferential center line. The wedge followers and wedge drivers both have divergent edge sections that interengage and slide over one another as the driving wedges are dulled together by a clamping mechanism comprising, in a simplest form, a nut and bolt. As the driving wedges move toward the circumferential center line, they displace the wedge followers. The wedge followers engage the end portions of the clamping band and force it and the connector boot into a sealing relationship with the surrounding manhole riser:

Abstract: PATENT - Docket 9D-RG-17887 - Ghassemzadeh GAS BURNER WITH IMPROVED PRIMARY PORT ARRANGEMENT                     ABSTRACT An improvement to conventional atmospheric gas burners particularly advantageously applied to the type used as surface heating units in gas cooking appliances such as ranges and cooktops, which typically comprise a burner head having a plurality of primary burner ports formed at port locations equally spaced about the periphery of the burner head.  Improvement is realized by not forming primary burner ports at selected ones of the equally spaced port locations.  The unused port cations are selected so as to separate the primary ports into groups. ? reduction in the number of ports reduces the total port area thereby ducing the amount of primary air entrained in the air/gas mixture ivered to the burner.  In addition the resulting spacing of the groups ports has the effect of reducing the amount of secondary air per port ative to that which would be entrained by the same number of ports, if ally distributed about the periphery.  The net result being more trolled combustion under normal operating conditions and in particular der delayed ignition conditions.

Abstract: SURGICAL STAPLING INSTRUMENT                      ABSTRACT            A linear surgical stapling instrument includes a magazine for holding a plurality of undeformed surgical staples, and an upper jaw carrying the magazine and having opposed distal and proximal ends.  An anvil is formed with staple-deforming pockets, and a lower jaw carries the anvil and has opposing distal and proximal ends respectively configured to mate with the distal and proximal ends of the upper jaw thereby to place the magazine and the anvil in confronting relation.  A staple driver is carried in the upper jaw for driving staples held therein toward the anvil.  Further, the upper and lower jaws are configured such that, when their respective distal and proximal ends are mated, a gap exists between the jaws in an intermediate region between their respective distal and proximal ends. Finally, a pivotably mounted clamp bar joins the upper and lower jaws and when actuated compresses them together in the intermediate region thereby to narrow the gap and to increase the clamping pressure between the magazine and the anvil.  The instrument also includes a blocking system that prevents the jaws from being remated, once having been mated and having had staples in the magazine driven toward the anvil.  Still further, the instrument includes a coupling device for coupling the jaws and clamp bar together when the staple driver is actuated.
