SELF-CALIBRATING ULTRASONIC-BASED MONITORING SYSTEM

Systems, methods, and devices for determining distances inside a liquid filled container such as an oil tank. A combined ultrasonic signal receiver/transmitter with an attached reflector is immersed in the liquid. An ultrasonic signal is then transmitted from the receiver/transmitter and reflected ultrasonic signals are then received. One of the reflected signals is reflected off of the attached reflector and this reflected signal is then used to determine the signal's velocity and to thereby self-calibrate the system. Once the velocity in the liquid is known, the other reflected signals can then be used to determine the distance between the receiver/transmitter and at least one point of interest in the container.

EMPTY PRODUCT DETECTOR

The alarm mechanism of the invention signals the absence of a liquid from a source of aqueous liquid. The alarm mechanism comprises an alarm body having an inlet port and an outlet port; the inlet port in liquid communication with a source of liquid, the outlet port in liquid communication with a use locus. The alarm mechanism additionally comprises a float chamber placed in liquid parallel communication with the inlet port and the outlet port. The float chamber contains a float operably connected to a mechanical alarm. The float, as the chamber is emptied of liquid, reaches a position wherein a "low or empty product" signa l is generated. The apparatus operates by passing liquid through the body. As liquid in the source of liquid is depleted and is no longer available for passage through the body, the body becomes emptied of liquid as the source of pressure removes liquid from the body and particularly from the chamber causing the float to reach a position generating a signal.

Self-calibrating ultrasonic-based monitoring system

Systems, methods, and devices for determining distances inside a liquid filled container such as an oil tank. A combined ultrasonic signal receiver/transmitter with an attached reflector is immersed in the liquid. An ultrasonic signal is then transmitted from the receiver/transmitter and reflected ultrasonic signals are then received. One of the reflected signals is reflected off of the attached reflector and this reflected signal is then used to determine the signal's velocity and to thereby self-calibrate the system. Once the velocity in the liquid is known, the other reflected signals can then be used to determine the distance between the receiver/transmitter and at least one point of interest in the container.

EMPTY PRODUCT DETECTOR

The alarm mechanism of the invention signals the absence of a liquid from a source of aqueous liquid. The alarm mechanism comprises an alarm body having an inlet port and an outlet port; the inlet port in liquid communication with a source of liquid, the outlet port in liquid communication with a use locus. The alarm mechanism additionally comprises a float chamber placed in liquid parallel communication with the inlet port and the outlet port.

Washing machine water level control - by float with magnet in a differ-ential membrane valve unit

When the water level in a clothing or dish washing machine rises beyond its normal level, it flows into a float chamber causing a float to rise carrying a permanent magnet with it. The magnetic field is then insufficient to hold a ferrous valve which drops into its seating in the water flow chamber, blocking the outlet, the rapid rise in water press. causing membranes to seal the water channel. The purpose is to provide an accurate water level monitor, with rapid cut-off in the water input, in a system unaffected by dirt or corrosion.

Float position determining appts. - uses counter for measuring time interval between application of current pulses to conductor to reception of mechanical noise

The position of a float indicates the level of liquid in a reservoir. The position is detected from the time interval between an input current pulse to a magnetic assembly and the subsequent mechanical pulse it generates. A stainless steel conductor (1) is anchored (2) in the base of the reservoir (3) and is maintained in position by a compression spring (4). The spring is isolated by an insulating ring (5). A semi-circular magnet (9) on the float concentrates the flux in the conductor. Other magnets (12,14) are located just below the lowest level and just above the highest level resp. Current pulses from a generator (16) are detected in the conductor by a coil (17). A piezoelectric microphone (18) senses the mechanical pulse generated as the current pulse passes the float assembly and a counter (20) determines the float position.
