Title: Gasket having multiple regions of different densities  and thicknesses and method of manufacturing same
Inventor: BELTER JEROME G
IPC: B29C70/70
Filed: 1987-07-08
Granted: 1996-01-09
Abstract: An improved gasket having multiple regions of different densities and thicknesses and a method of manufacturing same is disclosed.  First and second laminae of compressible gasket facings can be utilized to form a finished gasket or gasket blank having two different density regions.  The first lamina has a shape which corresponds to the overall shape of the gasket.  The second lamina has a shape which corresponds only to those regions of the gasket for which a higher density is desired.  The first and second laminae are aligned with one another in overlapping planar relationship and pressed together by a die having opposed flat surfaces.  When so pressed, the second lamina is pressed into and combined with the first lamina so as to form a unitary gasket having flat facing surfaces and two different density regions.  The higher density region is defined by that portion of the first lamina material which was overlapped by the second lamina during the pressing operation, while the lower density region is defined by the non-overlapped portion of the first lamina.  Multiple laminae of the gasket facings having different shapes may be utilized in this manner to form gaskets or gasket blanks having additional regions of different densities.  In alternate embodiments of the present invention, the flat surfaces of the die may be provided with grooves or raised embossments in certain areas.  When the laminae of the gasket facings are pressed together as discussed above, the portions thereof engaged by the grooves or embossments are compressed differently than the other portions engaged by the flat surfaces of the die.  Those differently compressed portions of the finished multiple density gasket blank have not only a different density than the other portions of the gasket, but also have a different thickness than the other portions of the gasket.  If a finished gasket is not initially formed by the the method of the present invention, the gasket blank so formed can be cut or otherwise machined in any conventional manner to form the finished gasket.

Title: Apparatus for collecting dust from gas
Inventor: REICHEL DIETER
IPC: B01D46/24
Filed: 1987-07-09
Granted: 1992-12-22
Abstract: ABSTRACT              For a collection of dust from gases at tempera-tures up to 900°C and under pessures up to 20 bars by means of gas-permeable two-dimensional filter elements, an appa-ratus is proposed which comprises a pressure-resisting cy-lindrical outer housing, which contains a gas-tight pear-shaped inner housing, which is movably mounted in the outer housing by a means of a heat-insulating carrying structure and is provided with a tubular gas outlet port and comprises a cambered bottom, which contains cylindrical filter elements. A pressure-confining gas-tight compensator is provided be-tween the tubular gas outlet port of the inner housing and the outer housing. Because the "pressure-confining" and "supporting" functions are separate, the design problem how the internal components, which will be subjected to tempe-ratures up to 900°C, can be joined to the pressure-confining wall of the outer housing, which must not be heated above 200°C.

Abstract: F-3964(4119) CRACKING CATALYST           ITS PREPARATION AND USE          .                           ABSTRACT             New catalyst compositions of superior hydrothermal stability, which evidence increased gasoline plus distillate yields, improved coke selectivity and reduced C4- Gas yields, are based on framework dealuminated faujasitic zeolites having a framework silica to alumina molar ratio of from about 5 to 100.  In a preferred embodiment, an "ultrastable Y" composited with a matrix is subjected to a treatment with a source of aluminum and rare earth compounds followed by hydrothermal treatments to improve the hydrothermal stability and selectivity of the catalyst for catalytic cracking.  This is evidenced by higher gasoline plus distillate yields and lower coke and gas production at lower catalyst usage per barrel of feed relative to commercial cracking catalysts currently being used.

Granted: 1992-05-12
Abstract: Abstract of the Disclosure A method is disclosed of dehydrating a thin water based ceramic slurry coating on a foam pattern assembly having hidden internal surfaces.  The method comprises sequentially subjecting the coated assembly to a first warm air flow at a sufficient temperature and time to dehydrate and remove 60-80% of the water of the coating, and secondly subjecting the dehydrated coating assembly to low level microwave energy to substantially remove the remainder of the water in all of the coating, the dehydrated coating being devoid of bubbles or cracking.         The coating is made by use of a slurry comprising a thixotropic silica water suspension with the silica comprising only 40-50% of the slurry; the slurry also may include a small portion of clay and in some cases an acrylic or epoxy glue additive.  The pattern assembly or cluster is comprised of a plurality of molding patterns integrally carried by a gating system and common sprue, the patterns being at least four in number and radiating from the common sprue.  The patterns may be of a complex nature having tunnels or internal chambers not readily exposed, such as are present in an automotive manifold or head casting pattern.
