| 161 | Washer fluid spraying apparatus | US11484995 | 2006-07-12 | US20070017559A1 | 2007-01-25 | Kazuyuki Yamaguchi |
| In the present washer fluid spraying apparatus, when the amount of the remaining washer fluid in the tank is reduced, the buoyant force of the float does not have an effect to the valve member, and therefore the cross-sectional area of the flow passage of the valve member is reduced. Consequently spraying amount is limited compared to a case where there is a plenty of amount of remaining washer fluid. Therefore, compared to the structure that controls the washer pump driving status by detecting the remaining amount by a sensor, the driver of the vehicle can know that the amount of the remaining washer fluid in the tank is reduced while limiting the manufacturing costs. | ||||||

| Method for measuring the amount of liquid in a container, especially comprising means for making said liquid flow from said container to a point of use, in which the weight Pi in the container is measured at a time ti, this measurement being repeated at predetermined time intervals. The weight change nullPinullPinullPinull1 of liquid between times ti and tinull1, thus inull0, 1, . . . nnull1, is also measured so as to generate a signal indicating that the container may be considered as being empty when nullPi is less than a predetermined fraction of the weight of the container and/or of the liquid initially contained in the latter. | ||||||
| 163 | Fuel level indicator system | US10159071 | 2002-05-31 | US06672244B1 | 2004-01-06 | Michael J. Martin |
| A fuel level indicator system includes a housing member that is couplable to a fuel tank. The housing member is positionable adjacent to a vent opening in the fuel tank. The housing member defines an interior space. The housing member has a lower aperture facilitating environmental communication between the interior space and an interior of the fuel tank. The housing member has an upper aperture. A vent portion is coupled to the housing. The vent portion is in environmental communication with the interior space of the housing member via the upper aperture. The vent portion facilitates air flow from the interior of the fuel tank through the housing and out of the system. A whistle assembly is positioned substantially within the housing. The whistle assembly produces an aural indication of airflow through the housing member. | ||||||
| 164 | Level sensor with alarm | US584106 | 1990-09-18 | US5132669A | 1992-07-21 | Ronald E. Jackson |
| An alarm system for use in a salt-brine tank of a water softener has a sensor including a stem member having a lower end received in the bed of salt within the salt-brine tank and an upper end projecting above the bed of salt. An spaced pair of electrodes are supported at the stem member upper end and are responsive to direct contact with a brine solution inside the tank for generating the signal indicative of an abnormal condition. An electronic circuit is coupled to the sensor for generating an alarm which includes two counters coupled to a clock circuit such that any alarm indicative of the abnormal condition is delayed for a predetermined period of time after the sensor signals the abnormal condition, and the alarm is generated as spaced, short bursts of sound, the spacing between the bursts of sound being greater than the duration of the bursts. | ||||||
| 165 | Fuel filler alarm for boats | US315132 | 1989-02-24 | US5023608A | 1991-06-11 | Robert L. Delisle, Jr.; Douglas J. Goss |
| A fuel filler alarm for boats includes a housing, a whistle element on the housing and a suction ring on the housing. The suction ring is operable for detachably securing the housing to the hull of a boat adjacent a fuel tank vent thereon so that air passing outwardly through the vent passes through the housing and the whistle element. The whistle element is responsive to the outward flow of air through the fuel tank vent during a fuel filling operation for producing an audible whistling sound, while sound essentially stops when the associated fuel tank reaches a substantially full condition. | ||||||

| An all electronic, no moving parts, low cost, warning system, quickly and reliably alerts operator of malfunctions in levels, temperatures and pressures on trucks, farm implements, autos, boats, aircrafts, machinery, etc., which if not immediately attended to, may cause costly damage or even loss of life. Specifically gives aural and visual warning for: Low brake-fluid level, low transmission-fluid level, low engine-oil level, low differential-oil level, low coolant level, even low windshield-washer-fluid level, low fuel level, engine overtemperature, engine oil-pressure loss, loss of vacuum for power-brake assist, etc., in any single function, combination or extension, as pertaining to a particular truck, farm implement, auto, boat, aircraft, or similar machinery, all this being done by means of all-electronic parts, resulting into high reliability. | ||||||

| A warning device for a cylinder of liquefied gas under pressure for indicating to the operator when the level of gas in the cylinder is getting low, having a sleeve supported in the interior of the cylinder by a coupling connected to the tap of the cylinder and through which gas flows from the cylinder and which is closed off when the liquid falls below a predetermined level so that the consequent drop in pressure in the chamber sets a valve member into oscillation establishing a warning signal. | ||||||
