Abstract: A funnel apparatus for aiding in filling containers, such as gasoline tanks on lawnmowers and similar items, with a liquid material. The funnel apparatus comprises a main body member having a first predetermined shape. There is a throat member having a second predetermined shape and connected to a bottom portion of the main body member for insertion into such container to be filled. A pair of adjustable stabilizing legs are engageable with the main body member for preventing the funnel apparatus from tipping over during filling. The adjustable stabilizing legs are disposed in spaced apart relationship. There is also an indicating means engageable with at least one of the main body member and the throat member for indicating what level such liquid being added to such container is at.

Abstract: A limit-level sensor for measuring level of a liquid has a resistance element which has an electric resistance which suddenly varies a transition temperature which lies above the maximum liquid temperature. The resistance element is first of all heated by electric current. Thereupon, the electric resistance of the resistance element is measured. When the resistance element is covered with liquid, the heat generated by the electric current is led away so that the temperature of the resistance element is less than its transition temperature. If the resistance element is not covered by liquid, this heat is scarcely led away, so that the temperature of the resistance element remains above the transition temperature.

Abstract: An apparatus for maintaining a water supply in a stand supporting a Christmas tree is provided. A rigid funnel body comprises integrally formed top, center, and bottom portions. The funnel has a frusto-conical cross-section that tapers from the top portion to the bottom portion. A flexible coupling is integrally formed between the portions of the funnel to hold them in a desired angular relationship. An indicating system is affixed to the top portion of the funnel. The indicating system indicates when the water supply in the stand has fallen below a desired minimum level. A water level device at the bottom portion of the funnel is coupled to the indicating device by a connecting member. The water level device actuates the indicating system.

Abstract: Filling units for supplying small tanks or the like with gasoline, kerosene, or other flowable materials which attach to an inlet to such a tank. When the filling unit is in a fill position, a displacer section occupies a substantial volume within the tank. It allows the person filling the tank to supply the liquid until the tank will accept no more and the liquid reaches a predetermined level in a funnel portion of the filler. Thereafter, manipulation of the displacer section vertically within the tank, as for example by sliding a section of the overall unit upward, accommodates all the liquid remaining in the funnel up to such predetermined level within the tank by occupying the volume previously occupied by the displacer section and thereby completing the filling of the tank to a full condition without any spillage.

Abstract: A filling element for filling machines is provided and includes a liquid flow valve, which comprises a valve body that can be moved back and forth in a filling element axis between a position that closes the liquid flow valve off and a position that opens this valve. Also provided is an electrical probe for determining filling heights of liquid material in containers. The probe includes a first probe element that projects beyond the underside of the filling element and has an electrode, and a second probe element that at least partially surrounds at least part of the first probe element. The lower end of the second probe element is spaced further from the underside of the filling element than is the first probe element.

In a first embodiment, the device includes a receiver assembly having a horizontal bottom wall and a vertical side wall integral with the bottom wall, providing a receiver cavity for temporarily holding the waste liquid. The vertical side wall defines a cylinder concentric with a standard fifty-five-gallon drum having a top with an opening in it. The receiver assembly fits snugly over the top of the drum, and a drain tube extending downward from the bottom wall fits into the opening in the top of the drum. In a second embodiment, the device includes a receiver assembly having a horizontal bottom wall and a vertical side wall integral with the bottom wall, providing a receiver cavity for temporarily holding the waste liquid. The device further includes a drain pipe leading from the receiver assembly to a storage tank, and a frame supporting the receiver assembly during the transfer operation.

Abstract: Filling units for filling small tanks or the like with gasoline, kerosene, or other flowable materials which attach an inlet to such a tank. When the filling unit is in a fill position, a displacer section occupies a substantial volume within the tank. It allows the person filling the tank to supply the liquid until the tank will accept no more and the liquid reaches a predetermined level in a funnel portion of the filler. Thereafter, removal of the displacer section from the tank, as by sliding a section of the overall unit upward, allows the liquid in the funnel to enter the tank and fill the volume evacuated by the displacer section to complete the filling without any spillage. The overall unit may be removed from the tank each filling operation, or it may be designed to include a protective cap that fits over the upward-protruding portion of the unit, allowing the unit to remain mounted on the tank.

Abstract: A valve and coacting control circuitry for filling variously sized and shaped receptacles to an exact settable level with a relatively high impedance fluid such as maple syrup. Errors caused by bubbles are avoided by controlling the flow rate through a shaped orifice for essentially laminar flow. Dripping is eliminated by shaping the exit orifice to prevent gravitational emptying of the faucet cavity when the valve is closed. Sensing of the fluid is accomplished with a flexible wire probe, not sensitive to the receptacle shape but may be adjusted to a desired height, connected to a sensitive electronic circuit with a very high input impedance which allows sensing a voltage through the high impedance fluid. Once started, the filling process need not be monitored by an operator who is then free to do other tasks.

Abstract: A funnel has a float member which rises when a container is filled to warn the user to halt the pouring of a liquid. The funnel body has a conical funnel portion with three colored circles, of different colors, at separated levels on the cone. The float member, near its top, has color marks which match the color circles on the funnel cone. When the funnel nozzle (neck) is inserted into the container orifice, one of its colored circles will meet the lip of the container. The user fills the container until the same color mark on the float member reaches the top of a sleeve which guides the float member.

Abstract: A filling apparatus for filling liquid into a container to either of at least two levels has a liquid pouring gun unit for dispensing a liquid and a sensor thereon for sensing that the distance of a surface of the liquid from the end of the gun unit closest to the liquid is a predetermined distance and producing a signal when this distance is sensed. A liquid supply line is connected to the gun unit and has a valve therein and counter for determining the amount of liquid which is flowing in the liquid supply line. The sensor and the counter are connected to a controller, which in turn is connected to the valve. The controller can be set for actuation at either of at least two levels.

Abstract: An indicating funnel for filling a container through an opening is formed as two peripherally joined, coaxially arranged funnels, one nested within the other to define a cavity between adjacent funnel walls. A vertically movable fluid level indicator is reciprocatable between the funnels and behind a transparent wall portion of the exterior funnel for viewing between a first lowered position and a second raised postion. The indicator in its lower portion is operably associated with a float positoned within the lowermost portion of the cavity between funnels to indicate fluid level in a serviced container. The exterior funnel, at its intersection with an associated spout, optionally incorporates positoning flanges for maintaining funnel alignment and stability cooperatively with various sized openings. Additionally, the fluid level indicator may include a luminescent feature enabling enhanced visibility and a cap skirt portion lessening spill potential.
