Abstract:
An adhesive-backed film application tool (10) is provided for applying an adhesive-backed film (100) having at least first and second widths to a first surface (202) of a sash (200). The sash (200) further includes a second surface (204). The tool comprises (10): a directing structure (20) adapted to engage the second surface (204) of the sash (200); an application structure (30) pivotably coupled to the directing structure (20); and an element (40) for biasing the directing and application structures (20, 30) toward one another such that the directing and application structures (20, 30) are capable of being releasably clamped to the sash (200). The application structure (30) includes at least one rotatable element (37a, 37b) for applying the adhesive-backed film (100) to the first surface (202) and guide structure (160) for properly locating the adhesive-backed film relative to the rotatable element (37a, 37b) and the first surface (202). The guide structure (160) has a movable guide surface (172a) capable of being located in a first position corresponding to the first width (w1) of the adhesive-backed film (100) and a second position corresponding to the second width (w2) of the adhesive-backed film (100).
Abstract:
The present invention relates generally to separation of ions based on their transport properties. More particularly, the invention relates to separation of ionic mixtures and characterization of ions in gases using higher-order differential ion mobility spectrometry (HODIMS) enabled by asymmetric waveforms of fundamentally new types. The invention discloses a method and apparatus for separation of ionic mixtures and characterization, identification, or quantification of ions in a gas based substantially on the terms of third or higher order in a series expansion of ion mobility as a function of electric field intensity. This is achieved using a periodic, time-dependent electric field with novel waveform profiles that cancel or substantially reduce the contributions to time-averaged ion motion of the leading n (where n≧2) terms of that expansion, thereby achieving ion separations based substantially on the (n+1)th term. Separations using HODIMS with different n are expected to be highly orthogonal, enabling multidimensional separations employing HODIMS analyzers of different orders. The expected high orthogonality between HODIMS and mass spectrometry or ion mobility spectrometry would make HODIMS/MS and HODIMS/IMS combinations powerful analytical tools of broad utility.
Abstract:
A transponder device having multiple modes of operation, such as an active mode and a passive mode, wherein the modes of operation are selected in response to the strength of a received radio frequency signal. A communication system is also provided having a transceiver configured to transmit a radio frequency signal and to receive a responsive signal, and a transponder configured to operate in a plurality of modes and to activate modes of operation in response to the radio frequency signal. Ideally, each mode of operation is activated and deactivated independent of the other modes, although two or more modes may be concurrently operational.
Abstract:
A hot-gas stream (40) flows along the surface of a segment arrangement for shroud bands, in particular in a gas turbine. The segment arrangement comprises segments (20, 20′) arranged next to one another and in each case separated from one another by a gap (12). The hot-gas stream (40), in at least one section (70) of the gap (12), has a velocity component perpendicular to the direction of the gap from a first segment (20) to a second segment (20′). In this case, in said section (70), along that edge (26) of the first segment (20) which faces the gap (12), at least one film-cooling bore (52) connects a cooling-air chamber (50), allocated to the first segment, to the surface (22) subjected to the hot-gas stream (40), and/or, in said section (70), along that edge (26′) of the second segment (20′) which faces the gap (12), at least one edge-cooling bore (56) connects a cooling-air chamber (50′), allocated to the second segment, to the inside (28′) of the gap (12).
Abstract:
The invention relates to a device for operating an annular combustion chamber (15) which is equipped with combined burners (1) for liquid (4) and gaseous fuels (9), in particular burners of the double-cone design, each burner (1) having a fuel lance (3), with at least one additional air passage (7), for feeding the liquid fuel (4) and an airblast nozzle (2) for atomizing the liquid fuel (4), into which airblast nozzle (2) atomizing air (5) is fed from outside the burner hood (13), and an adjusting mechanism being provided for at least partly throttling the inflow of the atomizing air (5) during gas operation, wherein the adjusting mechanism is an external valve (21) which is arranged in a main feed line (19), coming from the compressor outlet (18), for the atomizing air (5), the main feed line (19) leading into a ring line (20), and the ring line (20) being connected to the head (24) of each fuel lance (3) via one branch line (23) each.
Abstract:
A floor covering system (10) including a first layer (14) of planar material and a second layer (12) of planar material. At least a portion of the second layer (12) is adapted for laminating engagement with the first layer (12) to define a floor covering. The system further includes a locating means for locating two or more of the second layers in a substantially aligned configuration, wherein the second layer (12) is adapted to receive the locating means.
Abstract:
A utility knife includes a body having a groove adapted to receive a blade. The groove has a plurality of tabs defined on at least a first side. The utility knife also includes a slide assembly device positioned in the body for sliding movement with respect to the body. The slide assembly device includes a housing with a first engaging member having a first protrusion and a second engaging member having a second protrusion releasably engaged with the tabs. The slide assembly device also includes a rocker attached to the housing that is operatively connected to at least one of the engaging members. The rocker is operable for disengaging the first protrusion or second protrusion with respect to the tabs. Disengaging one of the first and second protrusions by the rocker allows sliding movement of the slide assembly device with respect to the body.
Abstract:
The invention describes a device for separating dust and dirt out of flowing media. A curved flow path (1) is imposed on the flow (21), and heavy foreign bodies are separated out of the main flow by centrifugal force. The partial stream required to carry away the foreign bodies is aftertreated in a filter (11) and returned in purified form. Unlike with conventional filters, which have to process the entire flow of media, pressure losses during the separation of dust are minimized, and on the other hand no medium is lost for removing the dust load.

A locator tool assembly (10) comprising a locator tool (20) capable of being mounted to a vehicle door (200). The tool (20) includes at least one locator projection (42a, 42b) adapted to mount one or more film tabs (104). Each tab (104) forms a removable part of an adhesive-backed film structure (102). The assembly (10) further includes a stripper mechanism (50) associated with the locator tool (20) for use in removing the one or more film tabs (104) from the at least one locator projection (42a, 42b).
Abstract:
The invention discloses a process for treating a ceramic protective layer (3) which is applied to the surface (2) of a gas turbine part (1). The roughness of the ceramic protective layer (3) is reduced at at least one first location (5), and the original roughness is retained at at least one second location (6). The roughness is advantageously retained at locations (6) on a turbine blade or vane (1) which are at risk of detachment, while the roughness of the remaining surface (2) is reduced in order to reduce the heat transfer to the surrounding hot-gas flow.
