| 61 | Apparatus for the monitoring of floating roof position for storage tank roofs | US13247803 | 2011-09-28 | US08776596B2 | 2014-07-15 | Nikolay Nikolov Tzonev; Dale John Shpak; David William Sime; Kevin James Gans |
| A floating storage tank roof having a roof cover level monitor apparatus uses a flexible rod having a first end in contact with the storage tank cover bottom surface and a second end in contact with a base mounted to the top of the storage tank roof. As the rod flexes the second end of the rod is pushed into a slot within the base and against a resilient member within the slot. Within the slot are disposed proximity switches. As the rod second end sinks into the slot the proximity switches are actuated by mechanical or magnetic means. The spacing of the switches within the slot is calibrated to represent the level of the storage tank roof. A force transducer may also be used in lieu of the switches. | ||||||

| 63 | Liquid level detection | US12148255 | 2008-04-18 | US20090260432A1 | 2009-10-22 | Laslo Olah |
| The filling noise generated inside a pressurized container when liquid is injected into the container is detected at the outer end of a vent tube which extends into the container. When the level of liquid in the container reaches the lower end of the vent tube, the filling noise detected at the outer end is abruptly diminished. This abrupt change is detected and used to automatically terminate filling of the tank. | ||||||

| 65 | Water container in combination with a water level alerting apparatus | US11139577 | 2005-05-31 | US20050279287A1 | 2005-12-22 | Randall Kroeker |
| A water container in combination with a water level alerting apparatus comprises a receptacle for containing a suitable amount of water having a high and a low water trip point. A water level detection probe is co-located at each trip point. The probe sends an analogue signal to an integrated circuit where the signal is converted to a digital signal and amplified. The amplified signal triggers a human detectable alarm. The probe is either a conductive metal rod penetrating the receptacle side wall or a metallic strip encircling the exterior of the side wall. The device is operated by an integral DC power source such as a battery. | ||||||

| A method and an apparatus for measuring the amount of liquid in a container, and for causing the liquid to flow from the container to a point of use. The weight of the container is measured at several time intervals to determine the weight change of the liquid contained within. When the weight change is less than a predetermined fraction of either the weight of container weight and/or of the liquid originally contained in the container, a signal is generated to indicate that the container may be empty. | ||||||

| 68 | Accumulating whistling vent | US10375240 | 2003-02-27 | US06725800B2 | 2004-04-27 | Murray Hawkins |
| An accumulating whistling vent for indicating a level of liquid in a tank having a vent line is disclosed. The whistling vent includes a whistle housing reservoir which has mounting tubes extending from either ends. A whisle is housed in the whistle housing reservoir by insertion into one of the mounting tubes. The whistling vent is coupled between the vent line of the tank such that the tube containing the whistle is closest to the tank. As liquid is introduced into the tank an audible signal is produced by the whistle. Once full, air flowing from the tank through the vent line is replaced by the incoming liquid, thus muting the whistle. Excess liquid is accumulated in the reservoir prior to discharge from the vent line, thereby providing additional time to respond to the change in audible signal. In a preferred embodiment of the invention, a transparent reservoir is used to provide a visual indicator in addition to the change in audible signal. In another preferred embodiment of the invention a fuel filter and brass key chain whistle are used to minimize manufacturing costs. | ||||||
| 69 | Storage vessel overfill alarm | US681556 | 1996-07-23 | US6000359A | 1999-12-14 | James Lee Hudson, Jr.; Billy Tindol Hudson |
| A housing and float assembly allow for vapors or gases displaced during filling storage vessels to be redirected from a normal vent through a vapor or gas activated whistle or alarm without significantly restricting the venting rate of the vessel. The alarm produces a warning for the operator that the storage vessel has reached the predetermined high level to help avoid overfilling of the storage vessel. The device can be fabricated from readily available "off the shelf" parts and mounts into standard pipe threads or on to standard pipe flanges. The device can be provided as a kit to be assembled by the user. | ||||||
| 70 | Cassette type gas cylinder with remaining volume alarm unit and manufacturing method thereof | US244086 | 1994-05-16 | US5555905A | 1996-09-17 | Hideo Mifune; Yasuaki Nakamura |
| A cassette type gas cylinder, containing liquefied fuel gas, for giving an alarm when the volume of remaining fuel is reduced to a predetermined level or less in order to provide an advanced notice of replacement of the gas cylinder with a simple structure using burst energy of discharged gas. A valve 12 for opening and closing the discharge of liquefied gas is arranged at the center on one end of a container body 11a. A gas flow channel 17, with one end thereof opened into a gas space formed above the level of the fuel when the gas cylinder is laid horizontally, is connected to the valve 12. A vibrating member 27, for producing a sound when vibrated and caused to collide with a body by the burst of the fuel gas, is disposed in the gas flow channel 17. This vibrating member 27 is connected to a damping member 38 by means of a coupling member 29. The damping member 38 is located below a predetermined level of the liquefied fuel gas, and is subjected to resistance while moving in the liquefied fuel gas. The damping member 38 suppresses the production of a collision sound made by the vibrating member 27 by providing the vibrating member 27 with resistance when the level of the liquefied fuel is above the predetermined level, but does not suppress the production of the collision sound when the level of the liquefied fuel is below the predetermined level, thereby giving an alarm indicating the reduction of remaining fuel. | ||||||
| 71 | Toilet reservoir fill alarm | US453709 | 1982-12-27 | US4547768A | 1985-10-15 | Karel A. Kulhavy |
| A toilet reservoir fill alarm including water level sensors which can be positioned in the water reservoir tank of a flush toilet to detect the presence or absence of water at a desired level. A switch responds to the water level sensors and produces a control signal during the absence of a desired level. The control signal operates a timing circuit in order to produce an output signal at the termination of a predetermined time interval. Responsive to the output signal is an alarm circuit. In this manner, an alarm will sound should the toilet tank reservoir not refill during the predetermined time interval following the flushing of the toilet. | ||||||
| 72 | Signalling device for preventing spill-over from the fuel tanks of powered boats during filling | US51961374 | 1974-10-31 | US3924559A | 1975-12-09 | RENNER JR EDMUND W; SULE FRANK P; SULE WAYNE P |
| The device comprises two tubular extensions fixed respectively to the two opposing walls of a centrally located, generally cylindrical chamber. Those walls have respective central apertures in them which are aligned, as are both tubular extensions, on a common axis. In one form of the invention, a drain hole is located toward the periphery of the lower of the two walls of the chamber to prevent undue accumulation of liquid within the chamber. In another form, the tubular extensions have stepped, different diameter sections to accommodate different internal diameters of different hoses in which the extensions are inserted.
