摘要:
A fluidized-bed reactor comprising a chamber defining a hollow interior region and having a lower surface; a first input for introducing a contaminated gas into the hollow interior region; a plurality of catalyst nanoparticles within the hollow interior region and located on the lower surface, and a fluidizing input for introducing a fluidizing material into the hollow interior region, said fluidizing input having an outlet directed at the lower surface of the chamber, wherein the introduction of the fluidizing material directed at the lower surface fluidizes at least a portion of the catlyst nanoparticles located on the lower surface to create a gaseous dispersion of catalyst nanoparticles that reacts with the contaminated gas to produce a decontaminated gas.
摘要:
A water blended fuel composition comprising water, a normally liquid fuel and an emulsifying amount of at least one of a hydrocarbyl-substituted acylating agent and the reaction product of said hydrocarbyl-substituted acylating agent and an amine, an alcohol, a metal, reactive metal compound or a mixture of two or more thereof, wherein the hydrocarbyl substituent is a polymerized olefin having a polydispersity {overscore (M)}w/{overscore (M)}n greater than 5. Such polyolefin substituents can be prepared by polymerization of olefins in the presence of a calcined catalyst comprising a partially or fully neutralized ammonium salt of a heteropolyacid.

In a novel approach to golf club counter-weighting, directed to incorporation in a golf club at original manufacture as well as in the after-market, required secure longitudinal retention of the weighting device is accomplished by structure differing from known practice in that the required longitudinal retention is referenced to the top end surface of the golf club shaft by an annular flange configured at the top end of the weighting device and held securely between the cap portion of an original unmodified golf club grip and the top end of the shaft, thus accomplishing the required longitudinal retention of the weighting device with no need for grip modification or friction-gripping the interior surface of the shaft. The flange diameter is sized to fit closely inside the grip so as to also provide lateral retention at the top end of the thusly cantilevered weighting device.

An airflow system is provided that includes an interior strip that attaches an interior surface of a wall support assembly, a rear sheet attached to a rear exterior of the wall support assembly, a front sheet attached to a front exterior of the wall support assembly. The interior strip, rear sheet, and front sheet form a flame retardant interior channel that facilitates the transfer of airflow to and from an airflow source.

A computing device receives information that is representative of a location of a mobile device and uses the information representative of the location of the mobile device to select one or more maps corresponding to a retail establishment. The computing device also receives information that is representative of a customer and uses the information representative of the customer to place on the one or more selected maps indicia indicative of one or more locations within the retail establishment at which one or more items determined to be of interest to the customer are located. The one or more selected maps with the indicia are then provided to the mobile device for display.
摘要:
The present disclosure relates to a lawn sweeper designed to collect debris, such as grass clippings and leaves, from a surface such as a lawn, and more particularly to a lawn sweeper with an adjustable brush assembly and characteristics associated with improved storage of such a device. A user may adjust the brush assembly with respect to the housing without needing to move the wheels. The hopper assembly may include a panel movable to be placed in at least two orientations, thereby allowing a user to change the volume within which the hopper assembly may collect debris. Methods are also disclosed for adjusting the brush assembly and for storing a lawn sweeper unit.
摘要:
An exhaust aftertreatment system comprising a selective reduction catalyst, a NOx sensor or an NH3 sensor, a urea injector, and a dosing control unit, wherein the dosing control unit calculates the rate of urea injection by estimating the concentrations of NO and NO2 in the exhaust downstream of the SCR catalyst.
摘要:
A system receives from a customer having an associated rewards points account a price offer for an item. The system determines if the price offer for the item is below an established threshold price, e.g., a price a retailer would accept for the item. When the price offer for the item is below the established threshold price, the system determines an amount of rewards points to be redeemed by the customer to thereby allow the customer to purchase the item at the price offer for the item as received from the customer. The system then allows the item to be purchased by the customer at the price offer for the item as received from the customer in the event that the customer indicates a willingness to redeem the determined amount of rewards points from their associated rewards points account.
摘要:
A disposable test device consists of a first portion 2 having a fluid application port 5 to which a sample of fluid can be applied, and a handle portion 3 hingedly attached to the first portion 2 at a hinge portion 4 and which normally lies in the plane of the first portion. In use the device is held by the handle portion 3 and the first portion inserted into a measuring instrument. The handle is then deflected downwardly e.g. by the finger of a person to supply a drop of fluid to the port 5.
