摘要:
A fast, electro-optically switched zoom lens system operates across a broad spectral and thermal range while correcting for birefringent aberrations by means of a polarizing system that preferably includes polarizing reticles.

An electronically adjustable, combinational color filter device is provided for generating color light. Incoming light is split in a polarizing beam splitter/combiner into a first and a second element of light. One or more wave plates operate to modify the polarization state of the first element of light, and one or more dichroic reflective filters reflect portions of the first element of light having a predetermined wavelength. Similarly, one or more wave plates operate to modify the polarization state of the second element of light, and one or more dichroic reflective filters reflect portions of the second element of light having a predetermined wavelength. Reflected portions of the first element and the second elements of light are combined in the polarizing beam splitter/combiner to create color light. A spatial light modulator may be used to create color images.

This invention provides a process for control in oil and gas wells and related facilities of prokaryote caused souring, fouling and corrosion by reduction of problematic prokaryotes with naturally occurring lysing organisms, particularly sulfate-reducing prokaryotes by proliferating suitable virulent lysing organisms under conditions in which problematic prokaryotes thrive, including in a gas production wellbore. The process provides in situ proliferation of virulent lysing organism in a wellbore by providing both virulent lysing organisms and their host prokaryotes to selectively grow an effective control amount and concentrations of lysing organisms in a well formation.

Composite sputtering targets are made by hot pressing metal or metal containing powders into a backing plate which can be comprised of a different material with a depression formed in a surface or can be a used sputtering target of the same or different material. The depression corresponds to the erosion pattern of a target having the same geometry. The depression can be formed for example, by machining. The backing plate is loaded into a graphite die and covered with the sputtering material to form an assembly. A ram is added and the assembly with the ram is loaded into a hot press which is taken to an appropriate pressure and temperature under vacuum to form a composite sputtering target having a sputtering zone of densified sputtering material.

An elastic reinforcing cover is provided for a carton having a front panel, a back panel and two side panels being substantially at right angles, both side panels being substantially at right angles as to both the front panel and the back panel, The two side panels are generally parallel to one another and the front panel and the back panel are generally parallel to one another. A base is connected to the side panels and the front panel and the back panel. The base includes a slide resistant surface. The front panel, the back panel and the two side panels and the base are flexible and elastic. A strap is secured to and extends from the rear panel to the front panel, the strap and the front panel include a fastener to secure the strap to the to the front panel. The strap is located generally midway between the two side panels.
摘要:
In contrast to current industrial practice where alloying powders are added to starting powder metallurgy compositions either as powder mixtures or fully prealloyed powders, the present invention posits a diffusion bonded nickel-copper precursor additive mixture for direct one step addition to the starting powder metallurgy master blend composition. Segregation and dusting are substantially reduced and the mechanical properties of the resultant compact are improved.
摘要:
A composition for use with alloys including extra-fine nickel powder dispersed with a hydrophobic inorganic dispersant which is preferably high-purity silica treated with hexamethyldisilazane (fumed silica). The composition breaks and prevents the agglomeration of the nickel powder, thereby preventing weaknesses in alloys, like steel for example, formed with the nickel powder. A method for making an alloy with the composition includes mixing the nickel powder with other metals and/or nonmetals and the hydrophobic fumed silica to form an alloy blend, pressing the alloy blend, and sintering the alloy blend.

A system and method for recording and displaying a graphical path in a video game is provided. Upon initiation of a time-trial run, the player views a color-coded previous game path that dynamically changes color based upon a current elapsed time associated with the time-trial run, elapsed times associated with the previous game path, and character states associated with the previous game path. The previous game path may include, but is not limited to, a “best time” path, a “worst time” path, and an “average time” path. In one embodiment of the invention, the player may gauge game progress as measured against the “best time” path as displayed via a series of path markers, and subsequently varies player character input controls to optimize performance against a player character associated with the “best time” path.

An alternate display content controller provides a technique for controlling a video display separately from and in addition to the content displayed on the operating system monitor. Where the display is a computer monitor, the alternate display content controller interacts with the computer utility operating system and hardware drivers to control allocation of display space and create and control one or more parallel graphical user interfaces adjacent the operating system desktop. An alternate display content controller may be incorporated in either hardware or software. As software, an alternate display content controller may be an application running on the computer operating system, or may include an operating system kernel of varying complexity ranging from dependent on the utility operating system for hardware system services to a parallel system independent of the utility operating system and capable of supporting dedicated applications. The alternate display content controller may also include content and operating software delivered over the internet or any other LAN. The alternate display content controller may also be included in a television decoder/settop box to permit two or more parallel graphical user interfaces to be displayed simultaneously.
