Patent number: 8906126Abstract: The present disclosure relates to a fabric filter system, which may be used for removing particulate matter from a gas, such as a combustion process gas. The fabric filter system includes fabric filters (3) in a filter module. From the fabric filters (3), gas flows through a filter plenary space (5) and into an outlet duct (7). A flow control device (17) controls the amount of gas flowing into and through the outlet duct (7). The flow control device (17) comprises a guillotine-type damper (17). The guillotine-type damper (17) provides reliable and efficient control of the gas flow from the filter plenary space (5) into the outlet duct (7). A collar (21), fluidly connecting the filter plenary space with the outlet duct, improves the gas flow into the outlet duct (7).Type: GrantFiled: January 25, 2011Date of Patent: December 9, 2014Assignee: ALSTOM Technology LtdInventors: Rune Andersson, Anders Hjelmberg

Publication number: 20120107533Abstract: A method for the preparation of a coated substrate is provided, comprising the steps of providing a substrate; applying on at least one side of said substrate a first coating layer of a first aqueous composition comprising porous anionic pigment particles having a BET surface area of above 40 m2/g and a binder and applying on said first coating layer, a second coating layer of a second, aqueous composition comprising cationic colloidal silica or silicate based particles and polyalkylene glycol. It has been found that a substrate coated with the combination of the first coating layer and the second coating layer provides a suitable substrate for high-quality and fast-drying inkjet printouts.Type: ApplicationFiled: June 23, 2010Publication date: May 3, 2012Applicant: AKZO NOBEL CHEMICALS INTERNATIONAL B.V.Inventors: Kjell Rune Andersson, Erik Lindgren

Patent number: 7556674Abstract: A device (16) for separating particles (MP) from a flue gas flow (F) has a horizontal flue gas duct (18), through which the flue gas flow (F) is passed substantially horizontally from a first position (P1) to a second position (P2). In the first position (P1), the device (16) has a baffle arrangement (32), which comprises at least one plate (34, 36, 38) which is arranged in the flue gas duct (18) and which is inclined so as to deflect particles (MP) down to the lower portion (42) of the horizontal flue gas duct (18). In the second position (P2), the device (16) has a collecting means (40), which is arranged in the lower portion (42) of the flue gas duct (18) to collect the particles (MP) which have been deflected downwards by the plate (34, 36, 38) to the lower portion (42) of the flue gas duct (18).Type: GrantFiled: May 20, 2005Date of Patent: July 7, 2009Assignee: ALSTOM Technology LtdInventor: Rune Andersson

Patent number: 4921523Abstract: The mechanism comprises a piston and cylinder assembly operable to move mould side portion supports between mould open and mould closed positions thereof. A check valve (72, 74, 76, 78, 80, 82) is mounted in a passage (66) into the cylinder to allow fluid under pressure to enter the cylinder through the passage but to prevent exit of fluid through the passage. The check valve is mounted in a chamber (66f) defined partially by the end cap (60) and partially by a cover member (67) removably mounted on the top of the end cap (60). When the cover member (67) is removed from the end cap (60), the check valve can be removed.Type: GrantFiled: March 16, 1989Date of Patent: May 1, 1990Assignee: Emhart Industries, Inc.Inventors: Hermann H. Nebelung, Rune Andersson

Patent number: 3943716Abstract: The cable drum for the hoist cable of a hoisting device is driven by a hydraulic motor with a constant displacement that in its turn obtains drive fluid from a pump with a variable displacement. The displacement of the pump, and with that the speed and rotational direction of the cable drum, is operated by means of the rod of a piston in a double acting hydraulic cylinder, the piston being displaceable in the cylinder by means of pressure fluid, which pressure and direction of flow is adjustable by means of valves, which in their turn are operated electrically from a control lever.Type: GrantFiled: November 21, 1974Date of Patent: March 16, 1976Assignee: Linden Alimak ABInventor: Rune Andersson
