Abstract: A device, system, and a method are provided for notifying a user to replace a sacrificial anode in a pool or spa system. The device is provided in the form of a body defining a cavity, a sacrificial anode, and a sensor. The sacrificial anode substantially surrounds the cavity when the sacrificial anode is coupled to the body. The sensor is at least partially received into the cavity and is in communication with a pool automation system. The sensor is designed to transmit a signal to the pool automation system when the sensor detects water within the cavity. The signal is processed by the pool automation system, and the pool automation system may then transmit a notification to a user that the sacrificial anode is depleted.

Abstract: A free flowing, stable, water-soluble, powdered automatic dishwashing detergent with superior solubility, handling and storage characteristics is provided. The compositions comprises an inorganic polyphosphate carrier onto which is absorbed a nonionic detergent. The "loaded" carrier is mixed with powdered silicate and the other usual adjuvants such as bleach, pigment, etc. High levels of detergent are possible without adversely affecting the aforementioned advantages and superior characteristics.

Abstract: Gelation and setting of desirably miscible and pumpable crutcher slurries comprising sodium carbonate, sodium bicarbonate, zeolite and sodium silicate in an aqueous medium are retarded and often prevented by the addition to such medium of a citric material, such as citric acid and/or water soluble citrate, and magnesium sulfate. Alternatively, magnesium citrate may be employed. The addition of the citric material and magnesium sulfate (or magnesium citrate) appreciably lengthens mixing time available before setting of the mix, increasing it over such times for similar crutcher mixes not containing any anti-gelling material, or including citric material as an anti-gelling component but not incorporating magnesium sulfate.

Abstract: Gelation and setting of desirably miscible and pumpable aqueous crutcher slurries comprising sodium bicarbonate, sodium silicate and sodium carbonate are retarded and often are prevented by the addition of sodium sesquicarbonate (which serves as a source of sodium carbonate and sodium bicarbonate) after admixing of sodium bicarbonate, sodium carbonate (if added earlier) and sodium silicate. Desirably, citric acid is dissolved in the crutcher medium before addition of the sodium sesquicarbonate but its presence is not necessary.

Abstract: Gelation and setting of desirably miscible and pumpable aqueous crutcher slurries comprising zeolite (hydrated sodium aluminosilicate), sodium bicarbonate, sodium silicate and sodium carbonate are retarded and often are prevented by the addition of sodium sesquicarbonate (which also serves as a source of sodium carbonate and sodium bicarbonate) after admixing of the zeolite, sodium bicarbonate, sodium carbonate (if added earlier) and sodium silicate. Desirably, citric acid (and preferbly also, magnesium sulfate) is(are) dissolved in the crutcher medium before addition of the sodium sesquicarbonate but the presence(s) thereof is(are) not necessary.

Abstract: Gelation and setting of desirably miscible and pumpable crutcher slurries comprising sodium carbonate, sodium bicarbonate and sodium silicate in an aqueous medium are retarded and often prevented by the addition to such medium of a citric material, such as citric acid and/or water soluble citrate, and magnesium sulfate. Alternatively, magnesium citrate may be employed. The addition of the citric material and magnesium sulfate (or magnesium citrate) lengthens appreciably the workable crutcher time before setting, increasing it over such working time for similar crutcher mixes containing the citric material but not containing magnesium sulfate.

Abstract: A diaper comprising a rectangular body of absorbent material having apertures in the corners thereof. Fasteners having hook-like filaments of "Velcro" material are attached to the diaper by hooks integrally formed with the "Velcro" filaments and engaged in the apertures of the diaper.

Abstract: A new class of nitrogen compounds having an amide or ester linkage therein that are useful alone as softeners and in laundry detergent formulations.
