Abstract: A method for qualifying a mask for use in lithography is proposed. The method includes the following steps: a provision of an apparatus for qualifying a mask, the apparatus comprising an optical system and an evaluation and control device; a detection of at least one first phase difference of light at the mask by use of the optical system and the evaluation and control device; loading the mask; detecting at least one second phase difference of light at the mask by use of the optical system and the evaluation and control device; and implementing a comparison of the first phase difference with the second phase difference by use of the evaluation and control device.

Abstract: An indicator that the cartridge is draining slowly is placed on top of the cartridge. When slow draining causes urine to pool on top of the cartridge, liquid enters a float housing, causing an indicator to change color. The indicator is visible through a lens in a diverter. The indicator may be a disk that undergoes a chemical reaction to change color or a float that flips over to reveal a side having a different color. When the cartridge is operating properly, the float displays a first color. Flipping of the float reveals a second color to the observer. A color change indicates, such as by signaling, that the cartridge needs to be replaced.

Abstract: A computer unit has a browser is assigned a web application program cache and a configuration data file that specifies the web application programs storable in the cache and loadable from the cache without using an on-line connection to a communication network, in order to execute the web application programs. Update data for the configuration data file is read-in over an interface, assigned to the computer unit, and updates the configuration data file. A device for operating an application portal is configured such that the web application programs are selectable via the application portal. The programs are to be stored in a web application program cache. The device generates update data regarding the web application programs for the configuration data file as a function of the web application programs that may be selected; and provides the update data for transfer to the interface of the computer unit.

Abstract: A dry trap valve, such as usable in a non-flushing urinal and other drains, is employed to transport a fluid, such as urine or other wastewater to a sewer line for receipt and disposal of the wastewater. The dry trap valve includes a holder (e.g., a band holder) having an entry for receipt of the wastewater, a drain for disposal of the wastewater, a passageway (e.g., dent, depression or bypass) for conducting the wastewater from the entry to the drain, and an element e.g., a sealing band) for sealingly covering the passageway. The sealing band includes a hinged portion adjacent the lower end of the dent and is disposed to articulate upon flow of the wastewater from the dent and to permit the wastewater to flow to the drain and to close in the absence of the wastewater flow. Gases from the sewer line also press upon the sealing band in the absence of wastewater flow to further seal the dent.

Abstract: A forming section for a gap blade former type papermaking machine having a headbox which delivers a jet of papermaking stock between a conveying forming fabric and a backing forming fabric is provided. The conveying fabric moves in sliding contact over an impingement shoe on which the jet of papermaking stock is delivered at a point of impingement. A forming shoe located immediately downstream of the impingement shoe over which the backing forming fabric slides. The impingement shoe is mounted for at least one of pivoting and transverse movement so that a position of the point of impingement of the jet of papermaking stock can be adjusted by at least one of rotating the impingement shoe about a first pivot point and transversely shifting the impingement shoe. The forming shoe can also be mounted for movement.

Abstract: A urinal uses a sloped interior back wall to create a specific angle between an incoming urine stream and the back wall to effect an anti-splash phenomenon which involves the contact angle hysteresis and the coanda effect, thereby at least to minimize urine splashing. The contact angle hysteresis deals with the perpendicular angles at which the urine stream comes into contact with the back wall of the urinal bowl, that is the amount of angle degrees between the angle of surface of the bowl and the angle of the urine stream at the point of contact. This angle takes advantage of the Coanda effect so as to cause the fluid (urine) to run down the surface of the back wall to the bottom of the urinal, rather than splashing back. The Coanda effect is the tendency of a fluid jet to stay attached to an adjacent curved surface that is very well shaped. In one embodiment, the interior back wall is vertically sloped towards the user, at an angle greater than 20° from the vertical (e.g.

Abstract: A twin fabric hybrid forming section for paper making machine is described in which: the pitch of the fabric support elements decreases progressively in the machine direction; the level of vacuum applied to the forming fabrics through the dewatering boxes increases in the machine direction; the two forming fabrics together with the stock sandwiched between them traverse at least four separate and distinct vacuum zones within the forming section as they proceed in the machine direction; the level of vacuum applied to the last of the at least four separate and distinct vacuum zones is higher than the level of vacuum applied to the first of the separate and distinct vacuum zones; the level of vacuum applied to the at least four separate and distinct vacuum zones follows a preselected profile; and the dewatering boxes carrying the fabric support elements are arranged so that the fabric support elements are located in an alternating sequence on the machine sides of both of the forming fabrics.

Abstract: A cartridge for placement in a urinal includes a chamber having an entry for receiving wastewater (e.g., urine), a quantity of sealant floatable on the wastewater in the chamber for functioning as a barrier to odors that may otherwise emanate from the wastewater in the chamber, a sealant reservoir coupled to the chamber for containing a supply of the sealant, and a closed path sealant dispenser for dispensing the sealant from the sealant reservoir to the chamber for maintaining the sealant modicum atop the wastewater. The sealant dispenser includes a cap having a U-shaped channel, and opening, and an orifice entering into a throat in which the sealant floats. An air vent avoids the buildup of suction in the primary reservoir.
