Title: Safety syringe with piston to prevent users from having any kind of needle contact before and after use and from using said syringe more than once
Inventor: FEDERICO DEMETRIO
IPC: A61M/
Filed: 1988-09-28
Granted: 1991-03-27
Abstract: The present invention concerns a new syringe comprising a hollow cylinder, a piston with a needle, a little membrane and a spring, said components being assembled adequately but differently from traditional syringes. Indeed said needle is not set on the nib of said hollow cylinder, but rather at the base of said piston, while the hollow cylinder is not provided with a nib at its base, but rather with a membrane of variable thickness that closes the hole. Said piston is provided with a spring fixed to the very piston on one side and to said cylinder on the other side in order to pull back the piston.The functioning of said syringe develops through different phases.In the first phase the piston is pushed, thus making the needle come out from the cylinder through the membrane that closes the hole at the base of said cylinder. By either loosening the piston a bit or by manually pulling it upwards, the needle sucks the fluid into the cylinder cavity. It is envisaged that suction be longer with respect to the fluid to be sucked, therefore air will also be sucked. Since suction is carried out by means of the needle set on the piston, when suction ends the needle will draw back into said cylinder.During the second phase sucked air will be taken out to allow the needle to partially come out from the cylinder without fluid waste. This very operation is of utmost importance, as needle can be guided to the exact point of use.During the third phase injection is carried out simultaneously to needle penetration.In the fourth and last phase the needle is automatically pulled back into the cylinder cavity by the spring.Indeed, one of the benefits of the present invention is that this new syringe protects users from needle contact both before and after injection. Another benefit is that it is impossible to use the present syringe more than once. For this purpose a peculiar syringe body was designed, said body being formed by two parts with gradual fitting, which occurs each time the needle encounters a resistance. For example, during aforementioned first and second phases the needle encounters membrane resistance, and each time a resistance occurs both bodies embed into one another. In case a third resistance occurs, an internal prominence of the piston will close the needle chute, thus making both injection and suction impossible.

Granted: 1989-09-29
Abstract: The circuit has a switch coupled to a source of a voltage supply and has a control input responsive to a signal that is indicative of when electron beam current cut-off is required and related to a deflection signal for the electron beam for selectively conducting a current associated with electron beam cutoff. A capacitor is coupled to the switch and to a control grid of the cathode ray tube for storing a charge to develop an electron beam blanking voltage on the capacitor. The switch conducts the current related to electron beam cutoff when electron beam current cut-off is not required and disables conduction of the current related to electron beam cutoff when electron beam current cut-off is required. The capacitor is charged from the current related to electron beam cutoff that flows through the switch and is supplied by the source of the voltage supply when electron beam current cut-off is not required. The switch decouples the source of the supply voltage from the capacitor and places the blanking voltage developed on the capacitor across the control grid when electron beam current cut-off is required to cut-off the electron beam current in the cathode ray tube.

Abstract: Coolent is passed through the source of heat which has an output decreasing with time, then to a steam generator. The steam produced is passed to an air cooled condenser and the condensate is returned to the steam generator. The novel feature of the proposal is the addition of an auxiliary coolant whose flow-rate is gradually decreased in line with the decreasing heat output of the source. The auxiliary coolant flow is stopped when the heat output of the source is reduced to the capacity of the air cooled condenser.

Abstract: The data reduction apparatus is used in a system where speech signals, e.g. between telephones, are digitised in a circuit and later reconverted. Successive blocks of digitised data, e.g. 16m seconds thereof, are compared with each other in the frequency domain in a comparator. The conversion is effected in a circuit block. If one block is similar to its predecessor within pre-set limits, that block is not sent to the output, and instead a control signal is passed to the communication link to instruct a store to repeat the previous block at the other end of the communication link. Thus only critical data blocks are transmitted and the data rate is reduced.
