Abstract: An ice flap device (10) for a refrigerator comprises a flap unit (14) movable between an open position and a closed position, which unit releases a dispenser aperture for dispensing ice in its open position and blocks the dispenser aperture against dispensing ice in its closed position, as well as a motorized drive mechanism for driving the flap unit (14) between its open and closed position. According to the invention the drive mechanism comprises an a.c. motor (12) as well as a first electrical switch (26), which lies in the supply circuit of the a.c. motor and switches depending on the introduction of a receptacle into an ice dispenser compartment of the refrigerator, and by means of which the a.c. motor (12) can be turned on when the receptacle is introduced into the ice dispenser compartment for a movement of the flap unit (14) from the closed position in the direction of the open position.

Abstract: A system for accurately measuring and delivering a predetermined amount of fuel to a vehicle for a specified mission. This system rapidly refuels vehicles to a specific wet vehicle weight. The fuel loading value is determined based upon an algorithm, which accounts for interactions of mission duration, and/or mission payload weight, and/or mission environmental effects. The fuel loading is accomplished by using one or more measuring tubes with a floating valve, which precludes the continued flow of fuel into the tank when the predetermined amount of fuel is delivered. The measuring tubes can be of specific lengths each corresponding to an output of the algorithm or a single telescoping tube that enables varying the length of the tube. Each unique tube length corresponding to a unique output of the algorithm. An alternative system comprises different sized fuel bladders. These systems enable a rapid foolproof method of refueling.

Abstract: An applicator for fluid products includes a bottle enclosed by a cap having a partition defining in the cap an enclosed chamber. The partition includes an aperture which forms a passage between the enclosed chamber in the cap and the interior of the bottle. Rotating the cap for assembly to the bottle will place this passage in an unoccluded condition. As the bottle is inverted or shaken prior to use, the fluid contents of the bottle will travel through the passage and into the enclosed chamber in the cap. As the cap is rotated for removal from the bottle, a valve element will occlude the passage, trapping the fluid in the cap. Squeezing the cap to deform the sidewalls will force the fluid through a narrow bore in a supply stem leading to a dispensing tip.

Abstract: A float actuated valve for automatically shutting off the flow of fluid into a storage tank when the tank is filled to a predetermined level includes a pair of shutter plates movable transversely across the flow passage from an open position wherein the plates are retracted clear of opposite sides of the passage and a fully closed position in which the plates project into and cooperatively block the passage. A spring biased rotary trip plate underlying the shutter plates controls actuation of the shutter plates and may be held by first and second detents in rotative positions locating the shutter plates in the fully closed or a partially closed position. A lower float located within the tank releases the first detent to cause the trip plate to drive the shutter plates from the fully closed to the partially closed position when the level of fluid in the tank rises to a first level.

Abstract: A cap (10) for accumulators suited for the automatic refill of distilled water includes a main body (20) inside which there is a chamber (13) suited for the distribution of the distilled water through a hole (14). The hole is shut by a valve (32) controlled by a float (30) and connected to the float by means of a toggle joint. The toggle joint consists of a right-angled lever (35) and of a shaft (34) connected by a hinge to the lever and to the valve. The toggle joint ensures a very high force for the shutting of the valve, such as to stand high deliveries of liquid even under pressure. The cap is also equipped with a float (30) in the shape of an upside-down glass, that is, open at the bottom on the side of the liquid upper surface, so that the push on the float is determined by the over-pressure of the air and the gasses contained in the interior of the float. The overpressure increases in direct relation to the rising of the electrolyte level.
