Abstract: An animal resistant insert for a trash container is disclosed. The insert comprises a platform portion bounded by an edge and a flange portion extending from the edge of the platform portion at an angle. The flange portion terminates at a terminal circumference, the terminal circumference being approximately equal to the inner circumference of the trash container. The insert further comprises at least one handle extending from the platform portion. The insert may also comprise a rim of resilient material attached to the terminal circumference of the flange portion and at least one ventilation hole disposed on the platform portion.

Abstract: Disclosed is a computer-implemented method for estimating at least one requirement for migrating a computer-based application from a source platform to a target platform. The method comprises receiving identifications of respective migration tasks; correlating base costs to respective ones of said migration tasks; receiving identifications of migration attributes that affect migration cost; correlating cost factors to respective ones of said migration tasks, each of said cost factors indicating an amount by which a migration attribute affects the base cost of a migration task; and estimating a cost for each migration task, by applying the cost factors for each migration task to the base cost of the migration task.

Abstract: A manifold for a heat exchanger comprising a tank, a plurality of tubes arranged to receive fluid therein, a plurality of fins for interspacing the tubes, the fins extending along the length of the tubes to thereby define a core section, wherein the header section is formed with multi-point brazing interfaces for securing said header and said core section during a brazing process. One embodiment provides at least one doubled wall area in close proximity to the tube slot areas to form a structure of increased strength, permitting the material to be reduced in relative thickness. The manifold may be formed from flat sheet stock by extended side walls of the header portion joined by a separate cap to close a top portion of the manifold assembly for the purpose of collecting fluid to and from the tubes and said at least one inlet and outlet.

Abstract: A method and apparatus for laser cutting a target material is disclosed. The method includes the steps of generating laser pulses from a laser system and applying the laser pulses to the target material so that the laser pulses cut through the material. The laser pulses have an approximately ellipse shaped spot, have a temporal pulse width shorter than about 100 nanoseconds, and have an energy density from about 2 to about 20 times the ablation threshold energy of the target material. The laser pulses are applied to the material such that the major axis of the ellipse shaped spot moves parallel to the cutting direction. The spot has a leading edge and a trailing edge on the major axis, and the energy density of each laser pulse increases from zero to a maximum along the leading edge and decreases back to zero along the trailing edge.

Abstract: A power take off assembly for a heat exchanger for a vehicle. The assembly includes a rectangular frame having passages all the vertical sides to marry with core tubes from the heat exchanger, a face plate with a hole to position the power take off sleeve, a back plate with a similar hole, and a sleeve to allow the power take off shaft to pass though the assembly when installed in a heat exchanger for an automobile/truck. The assembly is pieced together and tabs located on the perimeter of the frame lock the front and back plates into place, the sleeve is inserted in the holes, and the entire assembly is brazed in a one shot process.

Abstract: Disclosed are various forms of an active, isolated &bgr;-secretase enzyme in purified and recombinant form. This enzyme is implicated in the production of amyloid plaque components which accumulate in the brains of individuals afflicted with Alzheimer's disease. Recombinant cells that produce this enzyme either alone or in combination with some of its natural substrates (&bgr;-APPwt and &bgr;-APPsw) are also disclosed, as are antibodies directed to such proteins. These compositions are useful for use in methods of selecting compounds that modulate &bgr;-secretase. Inhibitors of &bgr;-secretase are implicated as therapeutics in the treatment of neurodegenerative diseases, such as Alzheimer's disease.

Abstract: A simple but effective concept of using nylon, polypropylene or other flexible filament 2 as brush to create ring seals for pneumatic transfer carriers, thus affecting a virtually air tight seal 6 as well as superior durability due to the low coefficient of friction between the plastic brush filament and the conduit 7 through which it passes.

Abstract: The present invention concerns animal kennels or crates that provide a means for housing, containing and training animals, and in particular, domesticated house pets such as dogs and cats. The crate is collapsible so that it can be disassembled and transported in a convenient fashion. The crate is comprised of side panels, end panels and a top panel that define the boundaries of the crate. These panels are secured together through the use of edge pieces that are strong enough to maintain the integrity of the crate when placed under the stresses associated with an animal trying to escape, while also being flexible enough to provide for an easy means of assembling and disassembling the crate. Corner caps are placed on the corners of the crate and a removable base can be clipped to the crate. The edge pieces and corner cap also provides the crate with an aesthetically appealing appearance that reduces the perception of crates being cruel to the animal.

Abstract: A computer-based system for designing and using three-dimensional environments over a bandwidth limited network such as the Internet. The system allows an environment to be specified as a series of two-dimensional grids of text characters. Each character occupies a single grid position and represents an object in the environment. Objects can be given characteristics such as texture maps, and associated images and sounds that are triggered by events such as a user approaching the object. An object or image can be a hyperlink so that, when clicked or moved upon, the user is transported to a new location. A basic set of objects and media (images and sounds) is provided so that a designer of an environment does not have to perform low-level three-dimensional modeling. Objects can behave differently when placed near one another. For example, walls fuse together to provide a longer wall.

Abstract: An improved high average power, high brightness laser system. The laser system comprises an XeCI excimer amplifier, an XeCI excimer preamplifier, a means for generating a picosecond seed pulse tailored for the XeCI preamplifier and the XeCI amplifier and a means for focusing the output pulse laser beam onto a spot smaller in area than 100.times.10.sup.-6 cm.sup.2. We first produce a seed laser beam consisting of a series of bunches of short duration pulses with a bunch frequency in excess of 100 pulses per second. These seed laser pulses are produced by a Nd:YAG pumped dye laser oscillator with a cavity dumper. The pulses in the beam are preamplified in a multipass preamplifier and the pulses are then multiplexed in a pulse train generator into a larger number of lower power pulses.

Abstract: A transparent chuck is used to force a semiconductor wafer to take a prescribed shape. Any gap which is formed between the chuck and the wafer can be imaged through the transparent chuck. An interferometer is used to illuminate the gap with a narrow band illumination to create interference fringes in the gap. The fringes can be electronically imaged to create a digital input to a computer. Merit functions corresponding to the total volume of fringes in the gap or to the summation of nearest neighbor slopes of such fringes provide a measure of the thickness of such gap.

Abstract: An electric connector has a male connector housing and a female connector housing. The male connector housing is provided with slits substantially parallel with the engagement direction and cam plates respectively rotatable in the slits and integrally connected by a connecting member having a handle portion. The female connector housing is provided with an insertion guide wall extended from the bottom wall toward the mating face of the male connector housing, and vertical members erected at positions at the edge of the insertion guide wall corresponding to the slits. The small force to rotate the cam through a predetermined angle is converted into the pressure of the cam on the vertical members, and the male connector housing is pushed to the regular engagement position by reaction against the pressure.
