A battery-powered, liquid-detection alarm and shut-off system includes an elongated sensor, an electronic controller, and a spring biased shut-off valve assembly. The sensor comprises two partially exposed conductors separated by protruding ridges of insulation. The protruding-ridge configuration enables the sensor to detect small quantities of surface water and yet be insensitive to humidity. The electronic controller maximizes battery life and protects against false alarms caused by electrical interference. The shut-off valve assembly comprises a 1/4-turn ball valve and a valve-actuating assembly. The valve is set by being manually cocked to an open position, engaging a lever actuated cam and preloading a valve shut-off spring. The valve is then closed by momentarily passing an electrical current through a temperature-activated memory-shaped spring located on the valve assembly. The current is supplied by the electronic controller in response to detection of liquid by the sensor.

A process is disclosed for enzymatically converting lower alkyl alcohols to corresponding aldehydes and hydrogen peroxide in the presence of oxygen under process conditions which increase the catalytic capacity of alcohol oxidase enzymes. Such process conditions involve low temperatures, high substrate concentrations and an enriched supply of oxygen. Enzymes may be used in the form of whole cells, a soluble cell free extract or a highly purified fraction, and the process may be employed in batch or continuous operation.

Disclosed is a process for converting alcohols to aldehydes and hydrogen peroxide through the use of a methanol oxidase enzyme. The process involves introducing a lower alkyl or lower alkylene alcohol, such as methanol, ethanol, or allyl alcohol, as an aqueous solution into a reaction zone. Methanol oxidase enzyme that is stable in methanol concentrations of at least 0. 5% and formaldehyde concentrations of at least 1. 0% is also introduced into the reaction zone, which is maintained at an elevated pressure in contact with an oxygen-containing gas. The preferred methanol oxidase enzyme has the properties of the methanol oxidase enzyme produced by Hansenula polymorpha ATCC 34438. Both batchwise and continuous processes are disclosed. Also disclosed is a process in which a catalase is present in the reaction zone to decompose hydrogen peroxide as it is formed, so that the net reaction is the conversion of alcohol to aldehyde. In one aspect of that process, the aldehyde may be removed as a gas and subsequently condensed to an essentially pure liquid.

A flat motor. The flat motor comprises a substrate, a cantilevered, resilient lever arm mounted, by a passive end, on the substrate; and a shape-memory transducer acting on the lever arm wherein movement of the transducer deflects the lever arm.
