A fluid filtering apparatus and method may include keyed components to ensure that a correct filter element is being installed into a filter base, and to automatically actuate a fluid valve as the filter element is rotated into place on the base. Tool-less replacement of the element is provided. An embodiment of the element may include inner and outer substantially tubular-shaped media packs disposed about an axis, with one end of each of the inner and outer media packs being attached to an end cap of the element in a manner defining a fluid flow space between the inner and outer media packs for receiving a flow of fluid directed in parallel through the inner and outer media packs. A housing of the filter apparatus may include a flow tube configured to fit into the space between the inner and outer media packs.

A fluid filter arrangement is provided. The fluid filter arrangement includes a filter cartridge having a ring of filter media sealingly bonded to first and second end caps. The first and second end caps having first and second openings, respectively, fluidly communicating with the interior of the ring of filter media. The second end cap includes a seal surrounding the second opening. The fluid filter arrangement further includes an adaptor having at least one housing mount on the external side and an annular flange having a valve seat on the internal side. The adaptor is sealingly mates with the second the end cap.

An improved fluid filter arrangement having an improved fluid bypass is provided. The fluid filter arrangement includes a ring of filter media extending between first and second ends sealingly bonded to first and second end caps, respectively. The filter media defines an interior. Each end cap includes an opening in fluid communication with the interior. A grommet comprising at least in part a sealing material that is different than the material for the second end cap is received by the opening in the second end cap. The grommet is sealed against the second end cap. Furthermore, the grommet includes an annular-flange which includes an annular valve seat and a fluid bypass opening.

An adjustable transition duct support system for a transition duct that channels hot gases from a combustor exit to a gas turbine inlet of a turbine engine. The adjustable transition duct support system includes an adjustable forward transition flexible support assembly in contact with a transition duct body, whereby the forward transition flexible support assembly may be formed from a base extending toward the transition duct body and first and second side support arms extending from the base to the transition duct body. The first and second side support arms may be formed from a plurality of flex plates spaced from each other with spacers that provide rigidity in circumferential and radial directions and flexibility in an axial direction. The number of flex plates used may be varied to accommodate different turbine engines. The adjustable transition duct support system may have natural frequencies for circumferential and radial modes above two engine orders.

A gas-turbine burner having a plurality of main swirl generators which each have an inlet flow opening formed by the main swirl generator edge is provided. In order to achieve a uniform flow of combustion air through the main swirl generator, the gas-turbine burner has an inlet-flow guide means with a flow guide surface which runs from one of the inlet-flow openings to an adjacent inlet-flow opening, to which the main swirl generator edges which form the inlet-flow openings are connected, and the flow guide surface widens from there radially upwards. The main swirl generators are central-symmetrically arranged around a pilot burner and the flow guide surface runs radially outside the main swirl generators.

A laser marker 28 includes fixed legs 64 and 66, and a retractable leg 76, extending therefrom. With legs 64, 66 and 76 extended, the laser marker 28 can be moved about a workpiece surface 124 to selectively locate the line mark 137. With the leg 76 retracted, the legs 64 and 66 can be moved along, a workpiece edge surface 140 to selectively locate the line mark 137. The laser marker 28 can be positioned precisely on a circular saw shoe 150 by placing the legs 64 and 66 within reference holes 180 and 182 on a platform 164 on the shoe. The laser marker 28 can be positioned precisely on a protractor platform 244 by locating the legs 64 and 66 in a first circular guide track and the leg 76 in a second circular guide track 111.
