Patent EP-0009909-A1 (EP)
Inventor: NICHOLSON CHARLES B
IPC: B05B15/02
Filed: 1979-09-18
Abstract: A spray nozzle for a dual-purpose shower system for conditioning felt or wire fabric in a paper making process has two operative conditions depending on the selected function of the shower system. In one condition the nozzle .provides a high pressure spray and in the other condition it provides a low pressure purging flow, the condition being determined by the relative location of an internal plunger (28) with respect to a surrounding tubular body (10) having a valve member (26) at one end thereof. The plunger (28) is slidable in the body (10) and has a through passage (40) for the flow of liquid through the nozzle, and the clearance between the plunger (28) and the valve member (26) determines whether or not a spray or a purging flow is discharged from the nozzle. The supply of liquid into the nozzle is controlled by co-operating openings (60, 20) and ports (62, 64) in the tubular body (10) and the plunger (28) respectively. These are arranged so that when the plunger (28) is in the spray position a greater area is open for the intake of liquid than when the plunger (28) is in the purging position. A spring (54) moves the plunger (28) into the purge position and liquid pressure acting on the-plunger (28) moves it to the spray position.

Abstract: An hydraulic system for actuating a swing-post mounted backhoe boom (19) comprises two double-acting hydraulic cylinders (17, 18) operated by a control valve (35). As the backhoe boom (19) swings into a swing stop, hydraulic fluid is trapped in the head end (28) of the swing side cylinder. This trapped fluid is discharged through a cylinder relief valve (47), thus absorbing the boom kinetic energy and providing a smooth deceleration of the boom. Fluid discharged from the relief valve (471 is routed to the rod end of the swing cylinder and the head end of the opposite cylinder. Because of the swing linkage geometry, the cylinder rod (30) of the other cylinder had passed over the pivot axis (16) about which the backhoe boom (19) was swinging and thus the piston (29) of the other cylinder was caused to move in the same direction as the swing side piston (29). The movement of this piston can be utilized to provide additional deceleration torque as long as no voiding is permitted to occur in the head end of this other cylinder. Voiding only occurs when the backhoe swing control lever (38) is released prior to the backhoe boom reach ing the swing stop. Voiding does not occur when the con trol lever (38) is maintained in a full power-on or is stroked in the power-on mode until the swing stop is contactes Fluid from the swing side cylinder relief valve is routed to provide the necessary fluid to prevent such voiding Th- routing of the fluid from the swing cylinder to the other cylinder assures that the boom deceleration is independent of whether the control lever is stroked or released.

Abstract: Crystalline aluminosilicates containing an organic nitrogen cation are prepared by mixing a source of silica, a source of alumina, a source of alkali metal, water and one or more substituted neopentyl amines having the formula
     wherein R 2  is H, OH or NH 2 , and R is a C 1  to C 6  alkyl group, thereby maintaining the mixture under conditions of elevated temperature and pressure, typically in the range from 80 to 210°C and 70 to 400 psig, for a time sufficient to effect formation of the aluminosilicate, typically not less than 4 hours. The molar ratio of silica to alumina in the initial mixture is suitably in the range from 10:1 to 150:1 and the amounts of alkali metal and neopentyl amine or mixture thereof are suitable in the range from 50 to 0.02 moles per mole equivalent of total silica and alumina in the respective sources. Depending on the ratio of silica to alumina in the initial mixture crystalline aluminosilicates having a mordenite structure or a ZSM-5 type zeolite structure or mixtures thereof may be prepared. Mordenites having a silica to alumina ratio greater than 10:1 and an alkali metal content less than 0.15% by weight can be prepared directly by crystallisation without any post-crystallisation treatment. 
     The aluminosilicates are used as catalyst supports in various organic conversion reactions. Catalytic compositions are prepared therefrom by depositing thereon one or more metal oxides.

Abstract: Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Reinigung von mit Schadstoffen belasteter Luft unter Verwendung von Sorptions- und Katalysatormassen. Aufgabe der Erfindung ist es, eine Befreiung von Luft von ihren Schadstoffen bei gleichzeitiger Verwendung von Sorptions- und Katalysatormassen zu ermöglichen, wobei überdies die Sorptions- und Katalysatormassen vergleichsweise hohe Standzeiten erreichen. Verfahrensgemäß wird dies dadurch erreicht, daß die dem Filter zugeführte schadstoffbeladene Luft mit z.B. SO2-, NO2-, NO- und HC-Verbindungen zuerst durch die angeordnete Natronkalkschicht, dann durch eine Katalysatorschicht, z.B. Hopkalit, eine partielle Oxidation der Stockoxyde vorgenommen wird, vorzugsweise NO in NO2 und anschließend durch die A-Kohle-Schicht geleitet wird und erwärmt über eine Aufheizvorrichtung einer zweiten Katalysatorschicht, z.B. Hopkalit, zugeführt wird, um CO in CO2 zu wandeln, wobei vorzugsweise hinter der Hopkalitschicht eine Kühlzone angeordnet ist, über die dann die gereinigte Luft der Kabine übergeben wird. Die Sorptions- und Katalysatorschicht sind entsprechend ihrer erforderlichen Temperaturerhöhung hintereinander angeordnet. Die Schadstoffmassen in der Anströmluft (1), bestehend aus z.B. SO2, NO2, NO, CO und HC, werden durch Zuführung ozonisierter Luft (10) in SO3 und NO zu NO2 gewandelt und mit den HC-Verbindungen durch die Sorptions- und Katalysatormassen gereinigt und gewandelt.
