Abstract: An apparatus disposed within a pressurized container for enabling product contained in the container to be dispensed at a predetermined constant pressure, which apparatus includes a vessel having first and second enclosures housing pressurized gas and a member exposed to the pressure in the container. Fluctuations of the pressure in the container cause the member to move to a first position when the pressure in the container equals the predetermined pressure and to a second position when the pressure in the container is below the predetermined pressure. Pressurized gas passes from the first enclosure to the container when the member moves to the second position, the passage of which is prevented when the member moves back to the first position.

Abstract: Apparatus and methods for making uniformly-sized and predictably-spaced droplets from high-temperature liquids. Liquid droplet generators having electromechanical driving elements are coupled to a power supply to apply pulsed excitation forces through a wall of a delivery tube to a high-temperature liquid, e.g., a liquid metal, epoxy, or polymer. The excitation forces generated by the driver induce capillary vibrations in the liquid within the delivery tube. Liquid jet streams having capillary vibrations when exiting an orifice break up into groups of substantially uniformly-sized liquid droplets shortly after leaving the orifice. Droplets may be produced in a uniformly-spaced series, or individually on demand in response to a single burst of force from the driving element. A heat source is also thermally coupled to the delivery tube to maintain the liquid in a high-temperature state.

Abstract: Orifice elements for use in valves for injecting fuel or a fuel-gas mixture. The orifice elements include two silicon plates, joined to one another. An upper plate has one or more injection orifices. The lower plate has a through hole introduced in it, through which a fuel jet can emerge. The lower plate follows in the downstream direction and includes a jet splitter. The jet splitter divides the through hole into at least two passthrough openings so that a dual-jet characteristic is produced or maintained for the valve. At least two conduits are formed between the upper plate and the lower plate. Gas is provided via the conduits and is mixed with the fuel discharged through the injection orifice. The injection orifice and the valve are particularly suited for injection systems of mixture-compressing internal-combustion engines having externally supplied ignition.

Abstract: A pouring spout 5 is mounted on the front surface of a carton 2. The pouring spout 5 pierces through an inner bag. Only a region which is slightly larger than the half of the inner bag 3 on the pouring spout side is adhered to the inner surfaces of the carton by a paste. As the content is discharged, since the movable portion of the inner bag is injected into the fixed portion fixed on the inner surfaces of the carton, as the content is discharged, the volume of the inner bag is decreased.

Abstract: An apparatus for measuring and displaying a time interval between a valve closure and subsequent termination of a flow at a spigot is provided. The apparatus has magnetic sensors coupled to a flow regulating valve for providing a signal indicative of a solenoid-activated valve closure and detectors for determining fluid flow. The detectors have an infra-red light source and associated photo-sensor mounted near the water outlet spigot such that when a fluid flow is present at the spigot, the fluid reflects light from the infra-red light source so that the associated photo-sensor provides an output signal. A differential amplifier compares the photo-sensor output signal with a constant to determine a water run condition. Logic circuitry is connected to the comparison signal output to provide a timer actuation. The timer measures and displays the time interval between a valve closure and subsequent termination of flow at a spigot. The apparatus may be embodied as a hand-held or stationary unit.
