  • Patent number: 9381518
    Abstract: Described herein is a process for preparing nano-suspensions, wherein the process comprises: providing an admixture of at least one active pharmaceutical compound, an aqueous dispersion medium, and milling media and applying thereto acoustic energy having a frequency of from about 10 hertz to 1000 hertz and which supplies a linear acceleration of from about 10 G's to about 100 G's (where “G” is the force of gravity) for a period sufficient to supply a nano-suspension having a D50 of less than about 1 micron, preferably less than about 500 nm. Described also are nano-suspensions having novel properties prepared via the inventive process.

  • Publication number: 20140123813
    Abstract: A combination can and bottle opener includes a housing, a power supply, a motor and a gear train. A wheel extends at least partially outside of the housing and is operatively connected by the gear train to the motor. At least a portion of the wheel is configured to engage at least a portion of a can such that the can rotates with the wheel. A lever is pivotally attached to the housing between a first position for accommodating at least a portion of the can and a second position for engaging and opening the can as the can rotates with the wheel. A corkscrew is at least partially surrounded by the housing. The gear train operatively connects the corkscrew to the motor such that the corkscrew rotates with respect to the housing upon actuation of the motor to engage a cork to facilitate removal of the cork from a bottle.

  • Publication number: 20140072689
    Abstract: A hot beverage maker is provided for making latte by frothing milk in a carafe before and/or while brewing coffee and directing the brewed coffee into the carafe for mixing with the frothed milk. An agitating element, extends downwardly from a frothing motor attached to the cover of a carafe into the carafe for frothing milk while coffee is being brewed in a brew head of the beverage maker. Brewed coffee is directed into the milk as it is being frothed and is mixed with the milk by the frothing elements to make latte. A lever assembly is selectively movable between an “On” and “Off” position. In the “On” position, terminal pins are moved into contact with terminal plates on the carafe cover to provide electricity to the frothing motor. In the ‘Off position, the terminal pins are moved away from contact with the terminal plates.

  • Publication number: 20040200514
    Abstract: A flushing system is used to clean and/or clear clogged sinks, waste pipes, and/or toilets. It consists of the following components: a control nozzle, a drain attachment, a toilet attachment, foot pedal liquid pump, and a water hose for connecting these components to function as a system. Since the flushing system utilizes the application of the liquid pressure principle, it is required to be connected to a pressurized liquid source when the user chooses not to use the foot pedal liquid pump. An example of a pressurized liquid source can be a water main. A water nozzle is used as an option to connect between the pressurized liquid source and the drain or toilet attachments to control the liquid flow. A pulsating jet of pressurized liquid can be delivered from the outlet of either the drain or toilet attachment to effectively clear clogged pipes by the opening and closing motion of the water nozzle.
