Abstract: A device for dispensing liquid scent includes a reservoir for containing liquid scent and a reducer tee disposed in an opening in the reservoir. The reducer tee has first, second and third orifices in fluid communication with one another, and the first orifice is located in the reservoir opening so as to be in direct fluid communication with the interior of the reservoir. The device also includes a pump having an inlet and an outlet. A first tube connects the interior of the reservoir to the pump inlet, and a second tube connects the pump outlet to the second orifice. Operation of the pump can be controlled, by a timer for example, so that a predetermined amount of liquid scent is dispensed through the third orifice at a predetermined time. An additional amount of liquid scent is returned to the reservoir via the first orifice.

Abstract: The present invention broadly applies to any fluid valve made up of a plurality of body components that create sealing lands where the body components are clamped together. The invention is further applicable to any such valves in which pressure differentials within the valve can cause fluid leakage in the region of these sealing lands. Fluid leakage is reduced by locating at least some of these sealing lands within a hollow clamp that holds the valve body components together. This clamping strategy that locates the clamping load where it is needed most is applicable to a wide variety of valves, but is particularly applicable to pressure control valves used in fuel injection systems that experience extremely high pressure differentials during their usage.

The apparatus is distinguished by a compact and economical configuration with good automatic filling of a space with mist.

Abstract: A rotary sprinkler system for both above-the ground and pop-up rotary sprinkler systems that controls the rate of nozzle rotation is disclosed. To maintain a relatively constant and controlled nozzle rotation, one or more chamfered spokes are included on the turbine of the sprinkler system. This turbine configuration together with a stator assembly that regulates fluid flow to the turbine control nozzle rotation despite variations in fluid flow. In particular, the chamfered spokes counteract the spin of the turbine in direct relation to the amount of water that bypasses the driving blades of the turbine.

Abstract: A liquid dispensing device for dispensing a liquid into the surrounding atmosphere employs a forced airflow through a small cross-section outlet nozzle (48) to draw the liquid from an adjacent exit nozzle (50) into the airflow. The air outlet nozzle preferably has a cross-section less than that of the liquid exit nozzle. The liquid exit nozzle may partially overlie the airflow path from the air outlet nozzle. The nozzle may be formed in or carried by a unit (24) having sealed connections with the airflow source (16) and a container holding the liquid.

Abstract: A fire's electrostatic field is used to directly control and extinguish a fire. A flame is, in and of itself, a virtual electrode. The inventive electro-static fire control and extinguishing device uses at least one common electrode and allows the fire's own electrostatic field to act as the other virtual electrode to repel the fire's flame, controlling the spread of the fire or to control its direction or to totally extinguish it. The electro-static fire control and extinguishing device exploits the electrostatic properties of the fire's flame, directly using at least one electrode set at the appropriate electrostatic charge to create the desired fire control while the fire acts as the second source of the electrostatic field in which the electrostatic attraction/repulsion interaction takes place. A high voltage electrostatic field is produced by a high voltage static generator and the desired charge level is delivered to the flame via a conductive grid.

The bag holding portion receives at least some of the bags and retains the bags at or near the material dispensing bin. The hopper assembly includes at least one opening device for opening the bags such that material within the opened bags is deposited into the material dispensing bin. The material dispensing bin is operable to dispense or broadcast the material over the targeted area. The material moving device is operable to move the bags of material along the receiving portion and toward the hopper assembly.

Abstract: A method for servicing companies associated with a spray device operating under guidelines of a regulatory body includes capturing in vitro actuation data associated with operation of the spray device and distributing the data to a company associated with an aspect of the spray device. The company may use the data for testing the spray device to ensure continued compliance with prior approval of the spray device by the regulatory body. The method may also include converting the data to parameters and distributing the parameters. Capturing the in vitro actuation data may include sorting the data based on in vitro age groups. Distributing the data may include providing the data in a format executable by an automated actuation system. The company receiving the data may be a drug development company, spray device manufacturer, or testing service. The regulatory body may be the Food and Drug Administration (FDA).

Abstract: The water jet of a conventional water jet device is straight, bundled and impinges with its complete cross-section onto the biological structure to be separated. This renders the separating section frequently imprecise and requires an increased flow pressure. Therefore, a water jet device with a novel separating nozzle (14) is furnished. This separating nozzle (14) is furnished with a nozzle channel (15), wherein the nozzle channel (15) is furnished with one or several twisted grooves (16) at the circumference of the nozzle channel (15) and wherein the number of the twisted grooves (16) and the diameter and the length of the nozzle channel (15) are placed in such ratio that the separating jet subjected to pressure is rotated.

Abstract: A novelty drinking straw assembly and its method of construction. The drinking straw assembly has a straw tube through which fluid is drawn. A first magnet is disposed within the straw tube. The first magnet is part of a rotor mechanism that rotates when fluid is drawn through the straw tube. A novelty object is disposed around a section of the straw tube. The novelty object has at least one second magnet. The magnets in the novelty object interact with the first magnet contained within the straw tube. This magnetic field interaction causes the novelty object to move about the straw tube whenever the straw is in use and the first magnet is rotating within the straw tube.

Abstract: An underground sprinkler with a pop-up head and a corresponding underground casing has two differentiated cylindrical parts, closed by a corresponding cover fixed to the pop-up sprinkler head, which, being a part coupled to the piston, pops-up due to the effect of the water pressure pushing the piston in a portion calculated for this purpose and which is so maintained for as long as the pressure lasts, to be recovered by the action of a permanent draw-spring when the pressure stops.

Abstract: In a dynamic flow rate adjusting method, a press-fitting degree of an adjusting pipe is adjusted to regulate a load applied to a needle by a spring in a direction for closing an injection hole. Thus, a dynamic injection quantity of an injector is adjusted. An injection command signal having one-minute long pulse width is applied to the injector to measure a static flow rate, from which the press-fitting degree is calculated. Thus, the press-fitting degree, in which variation in the static flow rate is taken into consideration, can be calculated. Therefore, variation in the dynamic flow rate of each injector, which is calculated from the press-fitting degree, includes only a dynamic flow rate error, while a static flow rate error is eliminated from the variation in the dynamic flow rate.

Abstract: A shower head includes a main body, a locking seat, a locking nut, a water outlet faceplate, an O-ring, an adjusting bolt, and a connecting unit. Thus, the water outlet faceplate is moved toward the main body by rotation of the adjusting bolt, so that the O-ring is closely urged between the water outlet faceplate and the main body, thereby forming a closely sealing effect. In addition, the water outlet faceplate is integrally formed with the locking sleeve, thereby decreasing costs of fabrication, and thereby simplifying the process of assembly.
