Patent CA-2023946-A1 (CA)
IPC: F01N13/16
Filed: 1990-08-24
Abstract: Abstract of the Disclosure The known muffler of an industrial engine, in which a channel communicating with an exhaust gas outlet is integrally formed on the inside of a muffler main body made of an aluminium diecast, and an inner lid is mounted to the open side of the channel to form an exhaust gas passageway serving also as a tail pipe, within the muffler main body as disclosed in Japanese Utility Model Applica-tion No. 63-127369 (1988) is improved.  The improvements reside in that a cross-section area of the channel is reduced gradually or in a stepwise manner from its inlet towards the exhaust gas outlet so as to prevent carbon from adhering to the exhaust passageway, and in that at the exhaust gas outlet is formed a projecting wall adapted to butt against the inner lid, integrally with the muffler main body so as to prevent the exhaust gas escape without passing through the exhaust gas passageway.
Patent CA-2026362-A1 (CA)
Inventor: WALLACE DONALD M
IPC: G01N1/40
Filed: 1990-09-27
Abstract: For testing the lead content in it, a water sample of substantial volume is forced through a waterpermeable receiver, preferably of fibrous filamentary cellulose such as cotton or rayon, to extract lead from the test sample and trap it in concentrated form in the receiver. The receiver is dewatered and treated with a color-developing indicator, preferably rhodizonic acid dipotassium salt activated by an acidic buffer solution to a pH of approximately 2.8, which buffer solution preferably includes sodium bitartrate, resulting in the development of a red stain indicating the presence of lead. The potency of the rhodizonic salt in a liquid carrier can be extended by utilizing an alcohol preservative in water in approximately equal proportions. The foregoing process can be performed by a test kit having a syringe for forcing the water sample through a detachable spout packed with fibrous cellulose and such kit includes color-developing indicating liquid and buffer for application to the packed spout after its removal from the syringe.

Title: Foam injected into a gravity override zone for improved hydrocarbon production
Inventor: SANCHEZ J MICHAEL
IPC: C09K8/94
Filed: 1990-09-28
Abstract: ABSTRACT       A process for increasing the production of hydrocarbonaceous fluids in a reservoir where foam is injected into a gravity override zone.  Foam is injected into the override zone via a well placed in the zone.  This foam injection well is positioned between an injector and a producer well.  During a steam-flooding or carbon-dioxide flooding, foam is injected into the override area via the foam injection well thereby blocking the override area and causing flooding fluids to be directed into an oil rich overridden area.          Foam utilized herein can be formed in-situ or ex-situ by a noncondensible gas and a surfactant.

Title: Low temperature plasma oxidation process
Inventor: DOBUZINSKY DAIVD M
IPC: H01L21/8242
Filed: 1991-09-17
Abstract: ABSTRACT OF DISCLOSURE      A process for forming a thin film on a surface of a semiconductor device.  The process involves formation of a  silicon  dioxide  film  by  plasma  enhanced  thermal oxidation, employing a mixture of ozone and oxygen which are generated separately from the reactor chamber in a volume ratio of about 1-10/1, preferably about 5-7/1, at a temperature  generally below 440°C,  preferably  about 350-400°C.  The process is used to form sidewall oxide spacers   on   polysilicon gates   for   field   effect transistors.   A  relatively  fast  oxidation  rate  is achieved  at  a  temperature  significantly  below  that employed in conventional oxidation processes,  and this serves to reduce dopant diffusion from the polysilicon. In addition, the resulting film demonstrates low stress with good conformal  step  coverage  of  the polysilicon gates.  Another use of the process is to grow thin gate oxides and oxide-nitride-oxide with a thickness of less than 100 .ANG..  An oxide film of uniform thickness is formed by controlling the temperature, RF power, exposure time and  oxygen/ozone  ratio  for  thin  gate oxide  (<100.ANG.) application in ULSI FET fabrication.

Abstract: ABSTRACT     Mixtures of light colored bis(C8 - C22 fatty acid) alkylene diamides, C8 - C22 fatty acid esters, and, if de-sired, metal soaps of C8 - C22 fatty acids can be obtained if, in a melt containing fatty acids with 8 to 22 carbon atoms, a part of the fatty acids are condensed to the cor-responding fatty acid diamides with diamines of the general formula NH2-R-NH2, in which R is a straight chain, branched, or cyclic alkylene group with 2 to 12 carbon atoms; a part of the fatty acids are esterified with fatty alcohols with 8 to 22 carbon atoms and/or multifunctional alkanols with 2 to 15 carbon atoms and 2 to 6 hydroxyl groups; and, if desired, a part of the fatty acids are converted to the corresponding metal soaps with basic compounds of divalent metals.  The condensation with the diamines is carried out before the esterification of the fatty acids with fatty al-cohols and/or multifunctional alkanols.  The mixtures so obtained can be used as additives in plastics.

Abstract: SLIDING DOOR OR WINDOW ARRANGEMENT          ABSTRACT OF THE DISCLOSURE              A sliding door system includes an outer frame, a fixed door panel and a sliding door panel.  The outer frame is formed from four frame elements of the same profile which can thus be mitered and connected by corner inserts.   The sliding door panel sits on a saddle provided on the outer frame and slides longitudinally of the saddle.  A weatherstrip element is carried on the sliding door  panel  between the saddle and a recess straddling the saddle.  The sliding door panel is biased away from contact between the weatherstrip and the saddle but is  moved  transversely  as  it  reaches  the  closed position by wedge members at the front edge and by a locking system at the rear edge to compress the weatherstrip to improve the sealing effect.   A portion of the saddle is removed adjacent the fixed door panel to allow the sliding door panel to be removed from the top edge.
