Title: System of operation of a teapot with two positions with functions of, respectively, 1) filling-emptying, 2) infusion-pouring, obtained by means of successive phases due to tilting.
Inventor: GUERRERA GIUSEPPE
IPC: A47J/
Filed: 1990-03-26
Granted: 1994-11-28
Abstract: The invention relates to the system of operation of a teapot which is hermetic in each part thereof and which can therefore be subjected to tilting operations to which two positions thereof correspond. As far as the first position is concerned, it corresponds to the functions of FILLING-EMPTYING and more particularly: in this position it is possible to fill the chamber with water and the receptacle with the tea mixture. The second position corresponds to the function of INFUSION-POURING, i.e. in this second position the water comes into contact with the mixture, thus allowing infusion. Furthermore, by means of a spout, this second position allows the tea already ready to be poured from the teapot into the cups. To summarize, the invention consists of a teapot which allows tea to be made without the need to take the tea leaves out after the time needed for infusion. In fact, a simple tilting ensures that the water is no longer in contact with the tea leaves, thus avoiding the operation of taking dripping objects, such as filters or bags, out of the teapot; the hermetic closure also allows the heat to be maintained in the infusion phase, as well as making the teapot easier to carry, while the possibility of dismantling allows more convenient and better cleaning.

Filed: 1979-09-10
Granted: 1986-04-30
Abstract: An auger advances grapes from an inlet aperture to a compression chamber whose exit is closed by a gate. When the chamber is full the auger rotation is halted and it is advanced into the chamber by a ram. The gate is opened to release the grapes when a predetermined pressure is reached within the chamber. Finally the pressure exerted by the ram is released and the auger is rotated out of the chamber. The cycle then repeats. The press provides a continuous pressing of the grapes against a controlled back pressure.

Motor unit structure is composed of two opposite set cylinders with pistons connected in axial connection, tightly penetrating through partitions walls for dividing cylinders and thus composing two separate chambers of fuel mixture or air blow. In the other electric motor unit for internal combustion engine construction versions, between the first two side piston there is set, connected with them third piston, creating an additional two chambers. While the motor is running pistons are moving only in scrolling fluctuation method and active movement take place during each stroke. Electric generator is composed of two or more cylindrical or annular coil ring shape windings, mounted on an outer surface of internal combustion engine cylinder walls and fixed magnets are mounted in moving pistons so that magnetic field flux change crossing the coil windings is greatest. In other versions the moving piston movement is changed mechanically into turning of flywheels and the same time electrical generator or the flywheel is a power generator rotor.
