A vessel composed of a sheet of flexible material, cut, rolled, and affixed to form a frusto-conically shaped base region. The sheet when rolled including an upper region having two opposing flaps, each flap delineated from a remaining portion of the sheet by a path along which the sheet is scored, so that the flaps, when folded along their respective paths, define a single elevated drinking portion having a spout formed between an extension of the base region and at least one of the two flaps.

Various embodiments described herein relate to a laser source for producing a pulsed laser beam comprising a plurality of ultrashort optical pulses having a variable repetition rate. In one embodiment, the laser source comprises a fiber oscillator, which outputs optical pulses and a pulse stretcher disposed to receive the optical pulses. The optical pulses have an optical pulse width. The pulse stretcher has dispersion that increases the optical pulse width yielding stretched optical pulses. The laser source further comprises a fiber amplifier disposed to receive the stretched optical pulses. The fiber optical amplifier has gain so as to amplify the stretched optical pulses. The laser source includes an automatically adjustable grating compressor having dispersion that reduces the optical pulse width. The grating compressor automatically adjusts this dispersion for different repetition rates.

A centrifuge for the separation of particulate matter from a volume of fluid includes an outer housing, a rotational member extending through the outer housing, and a rotor assembled onto the rotational member for rotation relative to the rotational member and relative to the housing. The centrifuge is constructed and arranged to enable self-driven rotation by the exit flow of fluid through jet nozzle openings defined by the rotor. The rotational member includes a fluid passageway and an exit opening for delivering fluid to the rotor. The rotor includes a divider plate that separates the interior of the rotor into a collection chamber and a separate jet zone. The collection chamber has a single fluid entry location defined by the divider plate for processing a single batch of fluid at a time.

A fuel water separator system includes a fuel tank for storing fuel and a fuel water separator fluidly coupled to the fuel tank for separating water from the fuel. A fuel pump has a suction side that is fluidly coupled to the fuel water separator for pumping fuel from the fuel water separator. The fuel pump has a high pressure side where the fuel has a higher pressure than at the suction side. A water pump, such as a venturi or a jet pump, is fluidly coupled between the fuel water separator and the fuel tank for pumping the water from the fuel water separator into the fuel tank. The water pump is fluidly coupled to the high pressure side of the fuel pump to receive the fuel at the higher pressure to drive the water pump.

A Fabry-Perot cavity comprised of three-dimensional photonic crystal structures is disclosed. The self-assembly of purified and highly monodispersed microspheres is one approach to the successful operation of the device for creating highly ordered colloidal crystal coatings of high structural and optical quality. Such colloidal crystal film mirrors offer high reflection with low losses in the spectral window of the photonic band gap that permit Fabry-Perot resonators to be constructed with high resolving power, for example, greater than 1000 or sharp fringes that are spectrally narrower than 1.0 nm. The three-dimensional photonic crystals that constitute the Fabry-Perot invention are not restricted to any one fabrication method, and may include self-assembly of colloids, layer-by-layer lithographic construction, inversion, and laser holography. Such photonic crystal Fabry-Perot resonators offer the same benefits of high reflection and narrow spectral band responses available from the use of multi-layer dielectric coatings. However, the open structure of three-dimensional photonic crystal films affords the unique ability for external media to access the critical reflection layers and dramatically alter the Fabry-Perot spectrum, and provide means for crafting novel laser, sensor, and nonlinear optical devices. This open structure enables the penetration of gas and liquid substances, or entrainment of nano-particles or biological analytes in gases and liquids, to create subtle changes to the colloidal mirror responses that manifest in strong spectral responses in reflection and transmission of the collective Fabry Perot response.

A centrifuge includes a housing that defines a fluid inlet port to supply fluid to the centrifuge and an axle cavity fluidly coupled to the fluid inlet port. A bearing is received in the axle cavity. A check valve is disposed in the axle cavity to minimize tampering, and the check valve is configured to control flow of the fluid from the inlet port. A rotor is configured to separate particulate matter from the fluid. The rotor includes an axle rotatably received in the bearing, and the axle defines a fluid passage to supply the fluid to the rotor. The check valve is normally biased towards a closed position where the flow of the fluid is shutoff. The axle is configured to open the check valve when the axle is received in the bearing.

The present invention provides a filter assembly containing a filter element and a container as a depot for a liquid additive. The container can include an inlet and an outlet, which are configured to allow a liquid to flow into the container mix with the contained additive and then flow out into the system. It has been observed that a liquid flowing through a filter assembly exhibits a pressure gradient within the filter. Consequently, the inlets and outlets to the container can be positioned to take advantage of the pressure gradient to enhance the addition of the additive to the liquid in the filter assembly.
