Abstract: Disclosed are methods and apparatus for cleaning heat exchangers and similar vessels by introducing chemical cleaning solutions and/or solvents while maintaining a target temperature range by direct steam injection into the cleaning solution. The steam may be injected directly into the heat exchanger or into a temporary side stream loop for recirculating the cleaning solution or admixed with fluids being injected to the heat exchanger. The disclosed methods are suitable for removing metallic oxides from a heat exchanger under chemically reducing conditions or metallic species such as copper under chemically oxidizing conditions. In order to further enhance the heat transfer efficiency of heating cleaning solvents by direct steam injection, mixing on the secondary side of the heat exchanger can be enhanced by gas sparging or by transferring liquid between heat exchangers when more than one heat exchanger is being cleaned at the same time.

Abstract: A machine tool control system. A machine tool controller is provided to receive commands from an input source and provide control instructions to a machine tool based at least in part on the commands. An operator interface is provided for inputting commands to the controller. The interface includes a display screen having images of individual command functions, the images being selectable on the screen to place into a sequence of command functions selected by an operator. A sequence generator indicates sequential ordering of the command functions represented by the sequence of images on the screen, such that a sequence of images on the screen selected by the operator is translated by the operator controller sequence generator into a sequence of commands to be inputted into the controller. The operator interface may include one or more images each representing a plurality of individual command functions in a defined sequence.

Abstract: A system for client caching of target addresses for network requests includes one or more processors and memory coupled to the processors, where the memory stores instructions executable by the processors to implement an application configured to direct network requests received from users to target servers over the network. The application attempts to update a current version of a local data object storing network addresses, where the attempt includes sending an update request to a redirecting server over a network. If the attempt succeeds, the application accesses the updated version of the local data object to obtain a target address for a network request. If the attempt fails, the target address is obtained from the version of the local data object that existed before the update was attempted. The application directs the network request to the appropriate server using the target address.

The transmitter assembly includes a frequency transmitter having an antenna and a first plurality of electrically conductive elements. The receiver assembly includes a frequency receiver having an antenna and an annunciator. Immersion of at least a portion of each of the first plurality of conductive elements in water causes the frequency transmitter to transmit a frequency via its antenna to the antenna of the frequency receiver, thereby causing a first annuciation by the annunciator.

Such a combined functionality film may be incorporated into a liquid crystal display (LCD) or LCD panel assembly.

Abstract: A wire grid polarizer may be formed by embossing a substrate surface with a mold having a plurality of grooves to form raised ridges; and depositing a metal line profile onto the ridges through one or more baffles oriented at an oblique angle to the normal of the substrate. The metal line profile is characterized by a cross-sectional width that tapers such that the metal line profile is wider proximate a vertex of the ridges than proximate a base of the ridges. A wire grid polarizer may comprise a substrate with a plurality of raised ridges and a plurality of metal lines on the raised ridges. The metal lines are characterized by cross-sectional metal line profiles having triangular shapes with a tip down configuration. Such a wire grid polarizer may be used in a liquid crystal display.

Abstract: Material may be obliquely deposited on a plurality of down-web oriented features on a substrate oriented in a down-web (z) direction or other than a cross-web (y) direction. A linear source generates a vapor flux of a material oriented parallel to the substrate and either parallel to the y direction or at an angle intermediate the y and z directions. The vapor flux impinges on the substrate at an oblique angle relative to the y direction. The substrate moves in the z direction relative to the linear source as the material impinges on the substrate. The vapor flux has a sufficiently narrow angular distribution in a plane perpendicular the substrate and parallel to the y direction that material deposits on predetermined portions of the down-web oriented features but not other portions, forming parallel down-web oriented lines of the material on the substrate.

Abstract: A method for forming a plurality of parallel metal lines on a substrate of thin film elastomeric material and a wire grid polarizer formed by such method. A sacrificial layer is formed by coating the substrate with a water soluble polymer while the substrate is stretched. The existing tensile force is removed, leaving an undulating topology of buckled sacrificial layer material. A masking layer is then deposited at an oblique angle and then fractured into parallel lines of material by application of a second tensile force. Unmasked portions of the sacrificial layer are removed by dry etch. A metallic layer is then deposited and a lift off process employed to remove remaining portions of the sacrificial layer and materials deposited thereover. Upon removal of the second tensile force, the substrate returns to its unstressed length with metal lines of predetermined periodicity thereon.
