Title: Compact flexible filter assembly for a fluid bed granulator, coater or dryer
Inventor: GUBLER SCOTT A
IPC: F26B25/00
Filed: 1995-04-24
Abstract: A novel filter assembly (8) for fluid bed granulator, dryer or coater machines (1) which utilize a rigid filter frame (10) consisting of a solid bottom plate (4), a donut-shaped top plate (3) with said top and bottom plates being connected by side rods (5) to form a cage-like frame work. Said rigid filter frame (10) is reusable, around which a pleated (13) reusable flexible filter bag (9) is fitted and clamped (7); top support plate (2) and mounting plate (12) are connected by a threaded rod (6) with a sealing gasket (11) between them. Said filter assembly (8) is located inside said fluid bed machine's exhaust path so that when the process air is drawn through the filter bag (9) it forms around and through the filter frame (10) to cause a pleated (13) accordion effect in such a way that it allows the use of flexible filter media in a configuration that takes less space, gives better support to prevent tearing, is much easier to change and clean between product production run and can be continuously cleaned during operation by alternately providing reverse air flow through it.

Title: Methods and apparatus for increasing acceptance and adjusting the rate of pressure variations within a prespecified range in precharged fluid storage systems
Inventor: GERSTMANN JOSEPH
IPC: F17C13/00
Filed: 1997-10-24
Abstract: Methods and apparatus for (a) increasing expansion tank "acceptance" (defined herein as working fluid storage capacity); and (b) adjusting the rate of pressure variations within a prespecified range in precharged fluid storage systems (for example, holding pressure down below a prespecified threshold value for a given volume of acceptance, stored water temperature level, etc.). A          "volatile" fluid (defined herein as a fluid having a boiling point within the predetermined pressure and temperature operating ranges for a given system), is used at least in part as the expansion fluid in an expansion tank included in a fluid storage system.  The volatile fluid, whether pure or combined with an ideal gas to temper the expansion fluids sensitivity to temperature, can be used to realize a relatively constant pressure "vapor spring" to make internal expansion tank pressure relatively independent of acceptance (where the term "relatively" in each instance is referring to a comparison between the use of an expansion fluid that contains a volatile liquid and one that does not contain such fluid).

Patent CA-2221644-A1 (CA)
Inventor: KUNDRAT DAVID M
IPC: C21C7/076
Filed: 1997-11-19
Abstract: A multiple stage process for obtaining Ni units from Ni laterite ores and sulfur-bearing Ni concentrates during production of nickel-alloyed iron, nickel-alloyed steel or nickel-alloyed stainless steel in a reactor equipped with top- and bottom-blowing means. Dried Ni laterite ore is charged into an iron/slag bath mixture containing dissolved carbon and a metalloid reductant such as aluminum or silicon. The laterite ore is melted while heat is generated by oxidation of the metalloid and carbon on the reactor. After the laterite ore is melted, top-blowing of pure oxygen and bottom-blowing of an oxygen-containing gas are ceased. Bottom injection of an inert stirring gas is begun. A sulfur-bearing Ni concentrate and aluminum are added to the bath. Sulfur from the sulfur-bearing Ni concentrate is transferred to and held within the slag produced from the laterite ore by controlling slag composition and temperature, degree of mixing of the iron/slag bath mixture by the inert gas and the carbon/metalloid concentration in the bath mixture. The sulfur-containing slag then is discharged from the reactor and the iron bath mixture is decarburized and refined to alloy specification. The extent of desulfurization by the slag determines the amount of sulfur-bearing Ni concentrate that can be added to the bath for a given slag weight. Total slag weight throughout the process should be within the range of 200 to 300 kg slag/MT bath mixture, the temperature of the bath should be maintained between 1500-1700°C, the slag basicity should be controlled between 1-3 and the compositions of Al2O3 and MgO in the slag should be maintained between 10-25 wt.% and  10-20 wt.% respectively.

IPC: B01J21/16
Filed: 1997-12-15
Abstract: A catalyst for exhaust gas purification is capable of purifying the hydrocarbons, nitrogen oxides and carbon monoxide present in the exhaust gas discharged from an internal combustion engine. The catalyst has a monolithic carrier and a catalyst layer containing Pd, Ba and a heat-resistant inorganic oxide, formed on the carrier. The amount of Pd supported on monolithic carrier is 100-300 g per ft3 of monolithic carrier (3.53x10-3 to 1.06x10-2 g per cc of monolithic carrier), the amount of Ba supported on monolithic carrier is 0.010-0.060 g per cc of monolithic carrier in terms of BaO, and the weight ratio of Pd and Ba as expressed as BaO is 1:2 to 1:10.  This catalyst for exhaust gas purification is superior particularly in hydrocarbon purification for a low-temperature fuel-rich exhaust gas (such as exhaust gas emitted during cold start) of automobile.

Abstract: A cylinder block is coupled to a cylinder block/cylinder head coupling surface of a cylinder head by ten bolts which are disposed to surround outer peripheries of combustion chambers.          In order to enhance sealability of an opening of a cooling water passage defined radially outside the bolts as viewed from the combustion chambers, the cylinder block and the cylinder head are further fastened to each other by a bolt disposed in the vicinity of the opening. Thus, the fastening force of the cylinder block/cylinder head coupling surface can be increased to increase the degree of freedom in design of the opening of the cooling water passage defined in the coupling surface.

Abstract: A defense system which includes a plurality of laser weapons.  The fields of regard of contiguous laser weapons are overlapped to create a battery or forward engagement missile defense system (FENSES).  The FENSES effectively increases the killing power of the laser weaponry thus reducing the kill time of such laser weaponry.  As such, the vulnerability of such laser weaponry to attack is greatly reduced.  Each laser weapon includes a command and control system that is integrated into a master control unit which issues commands to the fire units of the laser weapon systems in order to cause the fire units to act individually, or in groups or as a whole.  By increasing the kill power of the laser weaponry through advantageous laser placement, the effects of thermal blooming are greatly reduced.
