A method of applying a topical numbing agent to a nasal cavity without sedating a patient may include inserting a catheter into a nostril of the patient, the catheter having a first bend that forms a first angle such that at least a portion of the catheter is non-linear. The method may also include guiding a distal end of the catheter into the nasal cavity using a computerized tomography (CT) system by aligning a distal end of the catheter with a first cavity portion of the nasal cavity using a projection of the catheter within the nasal cavity on a CT scan of the patient, and moving the catheter within the nasal cavity while dynamically displaying the projection of the catheter by the CT system relative to the nasal cavity. The method may further include dispensing the topical numbing agent through the catheter into the first cavity portion.

Amine-aldehyde resins are disclosed for removing a wide variety of solids and/or ionic species from the liquids in which they are suspended and/or dissolved. These resins are especially useful as froth flotation depressants, for example in the beneficiation of value materials (e.g., bitumen, coal, or kaolin clay) to remove impurities such as sand. The resins are also useful for treating aqueous liquid suspensions to remove solid particulates, as well as for removing metallic ions in the purification of water.

Amine-aldehyde resins and uses thereof in separation processes

Amine-aldehyde resins are disclosed for removing a wide variety of solids and/or ionic species from the liquids in which they are suspended and/or dissolved. These resins are especially useful as froth flotation depressants in the separation of bitumen from sand and/or clay or in the beneficiation of clay (e.g., kaolin clay) from an impure clay-containing ore. The resins are also useful for treating aqueous liquid suspensions to remove solid particulates, as well as for removing metallic ions in the purification of water.

The present invention relates to polysaccharides that have been modified by providing azetidinium functionality thereto. Such functionality can be provided by crosslinking a polysaccharide with a resin having azetidinium functional groups. In one or more aspects, the polysaccharide can comprise one or more of starch, guar gum, alginate or derivatives thereof. Polysaccharides having azetidinium functionality according to the present invention are suitable for multiple uses. Such uses include, but are not limited to, removal of one or more solid materials from a liquid, beneficiation of an ore, removal of metallic ions from a liquid; providing oil from bitumen; and removal of mercury from synthetic gypsum. Other uses of the functionalized polysaccharides of the present invention include hydroseeding, dust control and erosion control.

Azetidinium-functional polysaccharides and uses thereof

Modified resins are disclosed for removing a wide variety of solids and/or ionic species from the liquids in which they are suspended and/or dissolved. These modified resins are especially useful as froth flotation depressants in the beneficiation of many types of materials (e.g., mineral and metal ores), including the beneficiation of impure coal comprising clay impurities, as well as in the separation of valuable bitumen from solid contaminants such as sand. The modified resins are also useful for treating aqueous liquid suspensions to facilitate the removal of solid particulates, as well as the removal of metallic ions in the purification of water. The modified resins comprise a base resin that is modified with a coupling agent, which is highly selective for binding to solid contaminants and especially siliceous materials such as sand or clay.

Washer toss game target

A composite proppant having a proppant substrate such as a porous ceramic or silica sand coated with magnetic particles and a method of propping a subterranean formation using a composition consisting essentially of the composite proppant.

Reducing flow-back in well treating materials

A slow release, particulate urea-formaldehyde polymer useful as a fertilizer for enhancing the extended delivery of nitrogen needed for plant development and growth and a granular fertilizer made with the particulate urea-formaldehyde polymer.

Slow release nitrogen fertilizer

A method for treating a seedling by dipping the roots of the seedling into a composition containing a slow release, particulate urea-formaldehyde polymer, which is useful as a fertilizer for enhancing the extended delivery of nitrogen needed for plant development and growth and to the composition useful as the root dip, or as a soil drench.

Infinitely water soluble, storage stable, low molecular weight, amine-modified resins/binders (e.g., phenol-formaldehyde resole resins and binders made therefrom) are used to produce low odor fiberglass products, such as fiberglass insulation for automobile headliners and room dividers. The cured, bonded fiberglass products have low TMA (trimethylamine) emission because the free formaldehyde in the resin has been scavenged with melamine, which resists thermal decomposition, and because the binder contains a relatively low urea content, which is a TMA contributor. The resole resin production process includes adding two different formaldehyde scavengers (e.g., melamine and urea) to produce a modified phenol-formaldehyde resole resin. This resole resin is produced into a binder by mixing with water, optionally in the presence of a latent acid catalyst (e.g., an ammonium salt of a strong acid). The binder can be applied to a fiberglass base material, dried, stored for an extended time period, and then cured and shaped into a final desired shape.
