International Classification:

B01F 5/12

US Classification:

3661822, 417406

Abstract:

Disclosed is a pump for controllably dispensing an additive into a stream of liquid and mixing therewith, the pump comprising: a pump body having a passage into which a liquid stream is introduced, and from which a combination mixture of the additive and the liquid stream is discharged; a turbine supported for rotation within the passage, the incoming liquid stream striking the turbine in a manner as to impart rotation thereon; an auger housing connected to the pump body, and having an entrance end into which an additive is introduced and an exit end from which the additive is discharged into the passage, such that the additive mixes with the incoming liquid stream; and a helical lifting auger mounted on a supporting drive shaft fixedly attached to the turbine, the auger rotatably disposed within the auger housing so as to produce a fluid flow through the auger housing, the lifting auger configured to accept the additive from the auger housing entrance end; and move the additive through the auger housing to the exit end into the passage, where the additive is mixed with the incoming liquid stream by the rotation of the turbine to produce the combined mixture of additive and liquid stream. Also disclosed are a pump including a gear system to change the torque of the lifting auger, and a method of mixing an additive with a liquid stream for fire fighting; pressure washing; spraying pesticides, fungicides, or antibiotics; spray application of fertilizers; abrasive water jet cutting; and spraying food in fish farming.

Abstract:

Provided are analogs of methylphenidate (“MPH”) that are useful for the treatment of drug addiction, attention deficit disorder, attention deficit hyperactivity disorder, and depression. The MPH analogs are extended duration compounds that bind to the dopamine transporter and the reuptake of dopamine in the afflicted individual's brain. Because of the extended duration of the MPH analogs, administration of the compounds is only required on a once or twice daily schedule.
