摘要:
A wastewater treatment system for communities not connected to sewer infrastructure. The wastewater treatment system comprises a control unit electrically coupled to an ecologic cleaning system (i.e. phytoremediation), activated sludges and disinfection process (i.e. ultra violet light) in a re-circulation and continuous flow arrangement.

Adjustable height control stick assembly for dual control of aircraft includes a single control stick for longitudinal and lateral orientation of the aircraft with the height adjustment allowing for correction of position prior to flight. The stick is connected to appropriate linkages to move the ailerons and elevator of an airplane or the rotor blades of a helicopter. When either the pilot or the copilot is flying the grip for the other is at a different height to that for normal operation. The invention replaces and makes adjustable the grip so that height of the grip of both pilot and copilot are the same as if they were flying and in control of the aircraft.

A gas diffusion substrate includes a non-woven network of carbon fibres, the carbon fibres are graphitised but the non-woven network has not been subjected to a graphitisation process. A mixture of graphitic particles and hydrophobic polymer is disposed within the network. The longest dimension of at least 90% of the graphitic particles is less than 100 μm. A process for manufacturing gas diffusion substrates includes depositing a slurry of graphitised carbon fibres onto a porous bed forming a wet fibre network, preparing a suspension of graphitic particles and hydrophobic polymer, applying onto, and pulling the suspension into, the network, and drying and firing the network. Another process includes mixing a first slurry of graphitic particles and hydrophobic polymer with a second slurry of graphitised carbon fibres and liquid forming a third slurry, depositing the third slurry onto a porous bed forming a fibre-containing layer, and drying and firing the layer.
摘要:
A convergent spray gun which combines a liquid resin and dry metallic powder externally of the nozzle of the spray gun that utilizes a pair of diametrically opposing passages disposed at 0.degree. and 180.degree. relative to the central resin discharging orifice where the central orifice is approximately 0.015 inch and the air for atomizing the fluids is approximately 0.187 inch and the atomizing angle is approximately 90.degree.. The metallic filler is added to the plume of the convergent spray at the low pressure section and the ratio of the fluids are controlled by a computerized system. The spray gun, controls and mixing chambers of the resin (two part) and powder fillers are housed in separate rooms and the dust where the powder fillers are metered is controlled.

A stringed musical instrument with a base portion and neck portion with an inlaid fretboard snugly secured within a recess between an upper wall and a lower wall on the neck portion is disclosed. The geometry of the upper and lower walls maybe optimized and includes walls that are substantially perpendicular to the face of the instrument, walls that are angled with respect to each other to define a wedge-shaped slot for slidably receiving and securing the mating fretboard therein, and walls that are angled to define inwardly extending protrusions that allow the fretboard to be “snapped” in place on the neck portion of the instrument. The fretboard may be rigidly secured to the neck portion with glue or the like or it may be detachably secured within the slot thereby allowing fretboards to be changed as desired for aesthetic or performance purposes.

A system and method calculate an optimal rates in a multi-source price engine in over the counter (OTC) markets. The system and method integrate rates from multiple liquidity sources to generate an output rate that can be transacted upon. Specifically, the system and method calculate a best bid/offer rate from input rates provided by multiple liquidity sources and apply a target spread and minimum profit to the best bid/offer rate to generate an optimal output rate. The optimal output rate may be a function of many factors, including market conditions, customer credit, and the preferences of the market maker or broker.
