Abstract: The invention provides aqueous solutions of (1) the reaction product of anhydrous trimethyl borate with titanium tetrachloride and (2) polyvinyl alcohol, preferably not exceeding about 0.5 weight percent of each. These solutions have a pH of about 1 but when ammonium hydroxide is added the pH may be raised to about 10 without precipitation of titanium or gelation of the polyvinyl alcohol.When the pH of the above solutions is adjusted to between about 2 and about 10, the solutions are photosensitive. When these solutions are in a confined zone, sunlight or actinic radiation in the range between ultraviolet light and the lower wavelengths of the visible spectrum causes oxygen from the air above the solutions to be consumed until it is all gone. Then, reduction of the colorless dissolved Ti(IV) compound to the dark blue Ti(III) state occurs without precipitation of the Ti(III) product or reoxidation to Ti(IV). The blue Ti(III) solution is quickly reoxidized by reexposure to air.

Abstract: A central heating system comprising a heat exchanger, heat dissipating means, and a connecting piping circuit for liquid flow, has a pump capable of pumping the liquid around the circuit at a lower or a high flow rate, the flow rate of liquid being sensed to control the means which supplies heat to the heat exchanger so that heat is supplied when the pump means is operating at its higher rate and is not supplied when the pump means is operating at its lower rate. The rate of operation of the pump means is determined by means which senses the temperature of the circulating liquid so that the pump means operates at its lower rate when the temperature of the liquid exceeds a selected value and at its higher rate when the liquid temperature is below a selected value.
