Title: Frost protection system for exposed water supply pipes - automatically shuts off supply and drains pipes when freezing temp. is detected
IPC: E03B7/12
Filed: 1987-03-25
Abstract: Main water supply pipes to houses and the piping (6) within the house are usually well protected from frost. However, householders often extend the supply system to a garage or other outhouse, and the additional piping may be above ground and liable to freeze up and burst. The present system automatically shuts off the additional supply and drains the external pipe, if freezing temperatures are detected. In freezing conditions, the temp. detector (11) triggers a control unit (10) which then energises two solenoids: one which operates a shut-off valve (8) and another which opens a drain cock (9) to empty the exposed pipework (6'). When the temp. rises above freezing point, the drain is closed and the supply reconnected. In its simplest form, the detector is a conventional adjustable bi-metallic thermostat and the controller is a simple transformer and rectifier circuit. Another version uses a temp. sensitive resistance and amplifier to operate a control relay.

Title: System and process to purify wastewater containing nitrogen compounds
Inventor: MULDER RONALD
IPC: C02F3/12
Filed: 1992-06-10
Abstract: The invention relates to a system for a process to purify (treat) nitrogen-containing wastewater by biological nitrification and denitrification. The system consists of at least two largely separated reactor compartments, a liquid inlet and a liquid outlet, the first, aerated reactor compartment being provided at the top with an overflow to the second, low-oxygen (oxygen-depleted) reactor compartment. The low-oxygen reactor compartment is divided, at the top, into a gas-freeing chamber and a settling chamber with an overflow to the liquid outlet. The first reactor compartment is provided with an air inlet and an air outlet situated above it. The first reactor compartment is optionally divided into two reactor compartments connected to one another, in which the supply of air causes mass circulation in the aerated reactor compartment. In accordance with the process, wastewater together with sewage sludge circulates on a support alternately through the low-oxygen and the aerated reactor compartment, after which the water is separated from the sludge and the sludge is returned to the reactor.
