A toilet seat lifting assembly for lifting a toilet seat includes a toilet that has a toilet seat which is hingedly coupled thereto for sitting on. a cup is operationally coupled to the toilet seat. A hydraulic rod is included that has a rounded end defining a ball, and the ball is rotatably retained in the cup such that the hydraulic rod is pivotable in the cup. A pedal housing is positionable on a floor adjacent to the toilet and the hydraulic rod slidably extends into the pedal housing. A first lever is pivotally coupled to the pedal housing and the first lever actuates the hydraulic rod to extend upwardly when the first lever is manipulated. A second lever is pivotally coupled to the first lever and a pedal is pivotally coupled to the pedal housing. The pedal is pivotally coupled to the second lever and the second lever manipulates the first lever when the pedal is stepped on for lifting the toilet seat.

A distillation process for separating a target component from a mixture containing a solvent and the target includes the steps of flashing off a vapor mixture of said solvent and said target in an evaporator, separating said target from said vapor mixture, and providing additional solvent to said evaporator to maintain the temperature of said evaporator substantially below the boiling point of said target. The process also includes the step of removing accumulated non-volatile components from said evaporator by allowing the non-volatile components to precipitate from a mixture of the target and the solvent.

A hybrid transducer having mass and compliance loading for permitting operation at a lower frequency. The mass loading may include the use of one or more pistons to couple the energy to the medium. A ring configuration of the transducer is also disclosed. The ring moves with maximum motion at one position and minimum motion at a position 180.degree. thereto.

Hybrid transducer

The transducer is one that combines magnetostrictive and electrostrictive/piezoelectric transducer effects to form a transducer with improved performance. A transducer is provided which the two aforementioned effects are mechanically coupled in series allowing cancellation of the motion at one end of the transducer and maximization of the motion at the other end thereof. In an alternate construction, respective transducer types are connected mechanically in parallel in which the pressure may be cancelled on one side and increased on the other side of the transducer array. Either the velocity of pressure cancellation leads to a transducer element or transducer array with unidirectional properties. This device described herein may also be used as an intensity measuring instrument or as an acoustic sound repeater. Moreover, because the magnetostrictive part of the transducer is inductive and the piezoelectric part is capacitive, they may be used together to electrically tune each other and thus not require additional electrical elements.
