Abstract: A high concentration, aqueous liquid surfactant composition is disclosed, comprising at least one amphoteric and/or anionic surfactant and a liquid-stabilizing amount of at least one liquid-stabilizing agent. The liquid-stabilizing agent is a succinic acid derivative, glutaric acid derivative or a combination thereof. The composition is pourable and pumpable at ambient room temperature.

Abstract: The motorized page turning device automatically turns the pages of a multiple-page musical composition silently and accurately. Each page of the musical composition is attached to a respective shuttle. Each shuttle is rotatably connected to a shaft and has two opposing notches at a bore passing through each shuttle. A drive pin passes normally through a main shaft portion of the shaft and individually mates with the notches of each shuttle. The main shaft is connected to a rotational drive motor which rotates the shaft and a respective shuttle approximately 180 degrees. A linear drive sleeve of the shaft is connected to a linear drive motor which axially advances the shaft and drive pin to the next shuttle.

Abstract: An analytic test device of a one time use type formed by concentrically disposed tube and sleeve members. A test reagent is present in the annular region between tube and sleeve. A liquid sample placed inside the tube is unable to enter the reagent containing annular region until relative movement between tube and sleeve opens a passage for sample flow into the annular region and contact with the test reagent.The test device is particularly adapted to testing urine samples.
