Title: Method for producing low carbon equivalent rolled steel shapes by controlled rolling
Inventor: TAKESHIMA YASUSHI
IPC: B21B1/088
Filed: 1993-11-05
Granted: 1998-04-21
Abstract: A method for producing a steel section by a rolling process including a rough rolling step, an intermediate rolling step and a finishing rolling step.          The intermediate rolling step comprises water-cooling the flange portion of the rough-rolled steel section between rolling passes in the intermediate rolling step to cool the surface layer of the flange to a temperature not higher than 750°C, and rolling the flange portion during recuperation of the surface layer of the flange at least one time between the rolling passes with a total draft not less than 20% and at an average rolling temperature not higher than 950°C and, after the finishing rolling step the outer surface of the flange is cooled at a cooling rate ranging from 0.5 to 10°C/sec depending on the thickness of the flange.  Also the carbon equivalent of the steel is a controlled.         The advantage is that steel sections of various contours and dimensions can be produced from minimized varieties of steel compositions.
Patent CA-2104016-C (CA)
Inventor: GREENALL JONATHAN
IPC: F24B13/00
Filed: 1992-02-14
Granted: 2004-07-20
Abstract: A stove (1) comprises a fire-box (4), and an ash-chamber (5) separated by a grate (19). Air intake means (21, 23) is provided beneath the ash-chamber. Air supply means (30) connected to the air intake means extends vertically past the ash-chamber and the fire-box to an upper region of the fire-box. Air delivery means (27) provides communication between the air supply means and the fire-box. In use fuel burning inside the fire-box causes external air to be drawn into the air intake means, through the air supply means and through the air delivery means to a region above fuel in the fire-box. External air is pre-heated by passing underneath the ash-chamber and past the ash-chamber and the fire-box during its passage into the firebox. Turbulence caused by an interaction between pre-heated air entering the fire-box and heated air already present causes smoky combusted air (F) to be pushed away from a door (35) at the front of the fire-box.

Title: Optical sensing apparatus for remotely measuring exhaust gas composition of moving motor vehicles
Inventor: JACK MICHAEL D
IPC: G01N21/25
Filed: 1994-09-12
Granted: 2000-06-13
Abstract: A light source (12) radiates an infrared beam (14) through the exhaust plume (22) of a motor vehicle (20) which passes in front of the source (12). A photosensor unit (18) includes a plurality of photodetectors (42,44,-46,48) which are spaced closely adjacent to each other and simultaneously sense the beam (14) after it propagates through the plume (22). An optical beam homogenizes or integrator (36) disposed between the plume (22) and the photosensor unit (18) causes the light incident on the photodetectors (42,44,46,48) to have uniform intensity.      The photodetectors (42,44,46,48) are sensitive to different wavelengths corresponding to spectral absorption peaks of constituents of the composition of the plume (22), including carbon monoxide (CO), carbon dioxide (CO2) and hydrocarbon (HC). A computer (24) computes the composition of the plume (22) as the percentages of the constituents based on the sensed transmittances of the respective wavelengths through the plume (22). A video camera (26) produces a video image of the vehicle license plate (28), and a combiner (24,32) causes the video image to be displayed on a video monitor (30) and recorded on a video recorder (32) together with the plume composition data.

Title: Elastic net-like substrate having a layer of fibers pre-bonded thereto for use in an absorbent article
Inventor: COLES PETER
IPC: A61F5/44
Filed: 1993-03-11
Granted: 1999-04-27
Abstract: In an absorbent article, such as a diaper or incontinence briefs, an elastic me mber (60) comprising a net-like elastic substrate (62) to which fibers (64, 66) are pre-bonded provides for a breathable elastic for use as a side- a waist- or leg elastic. The fibers that are bonded to the net-like substrate, for instance by hydro-entangli ng, ensure a soft and comfortable contact with the wearer's skin. In the side panels of the absorbent article, the elastic members have a large freedom of stretch without buckling taking place, thus reducing chances of leakage. When the elastic member is locat ed between the topsheet and the backsheet, a strong connection of topsheet to backsheet is established using a relatively small amou nt of adhesive.

Title: Misfire detection method for an internal combustion engine
Inventor: NOBLE GARDINER A
IPC: F02P17/12
Filed: 1994-11-01
Granted: 2003-05-20
Abstract: A method for detecting misfire in the combustion cylinder of a spark ignition internal combustion engine. The method includes the steps of charging an ignition transformer to a maximum ignition charge and initiating an ignition discharge between electrodes of the spark plug. The ignition transformer is then charged to a predetermined diagnostic charge which is less than said maximum ignition charge. If combustion is occurring within the cylinder, the temperature and pressure near the spark plug will be sufficient to allow the diagnostic charge to discharge. If the diagnostic charge does not discharge, the charge will be reflected back into the ignition transformer where it will be detected by a circuit as an indicia of misfire.

IPC: A61K8/49
Filed: 1994-06-27
Granted: 2006-01-24
Abstract: The invention relates to a novel process for the preparation of ergothioneine.      The process for the chemical synthesis of the different optical forms of ergothioneine is characterized in that it essentially comprises steps which consist in preparing or using an N .alpha.,N .alpha.-dimethy-lated histidine ester salt (optically active if necessary), treating this compound with an alkyl, alkenyl or aryl halogenothionoformate in the presence of a base, protecting the sulfur-containing substituent in the compound obtained, converting this protected compound to a compound of the trimethylammonium type and freeing the desired ergothioneine by saponification or acid hydrolysis, as appropriate. This process affords a better yield and ensures an excellent optical purity.
