Abstract: A liquid level gauge has a scale, a first float, a second float, a first level indicator, and a second level indicator. The scale is positioned on a sidewall of a storage tank containing two liquids. The first float is positioned in the tank and weighted to maintain buoyancy on the surface of a first liquid. The second float positioned in the tank and weighted to maintain buoyancy on the surface of a second liquid. The first level indicator is suspended adjacent the scale and connected to the first float to be responsive to changes in the level of the surface of the first liquid. The second level indicator is suspended in the level indicator cover vertically below the first level indicator and connected to the second float to be responsive to changes in the level of the surface of the second liquid.

Abstract: A liquid level monitoring system for a storage tank is disclosed. The liquid level monitoring system includes a liquid level gauge with a float positionable in the storage tank and weighted to maintain buoyancy on the surface of a liquid contained in the storage tank and a cable having one end connected to the float. The cable is moveable in response to vertical movement of the float caused by changes in the level of the surface of the liquid. A converter assembly is connected to the cable to convert the position of the cable into a position signal indicative of the level of the surface of the liquid in the storage tank. A signal transmitter is operably linked to the converter assembly. The signal transmitter is adapted to receive the position signal and to transmit the position signal. A remote monitoring system is located at a position remote from the storage tank.

Abstract: A process for producing menthyl glyoxylate hydrate (MGH), which comprises reacting a sodium or potassium salt of a monomenthyl maleate with a mixture of ozone and air in an aqueous reaction medium at a temperature of 15° to 50° C. to form MGH, wherein the reaction medium is circulated through a diffuser comprising a static in-line mixer or a packed column, and isolating the resulting MGH. The product is isolated from the reaction mixture, optionally purified by recrystallization, and dried. The ozone content in the ozone/air mixture is typically about 1% to about 5% by weight of the gas stream.

Abstract: A device for grasping and lifting a lid handle of a vessel, such as a Dutch oven. The device securely attaches to the lid of a vessel due to a spring-like mechanism that acts in conjunction with two elongated rods. A grasping structure, such as a hook, is attached to one end of a longer rod and a cooperating stabilizing structure is connected to the end of a shorter rod. Both rods have handles for squeezing by the user. When the user squeezes the handles of the rods, the lid handle can be engaged with the hook. When the user releases the handles, the spring-like mechanism fully extends and pulls the hook away from the lid handle, while the stabilizing structure, such as a horseshoe, is forced firmly against the lid.
