Abstract: Systems and methods relating to contact and interactions between a potential seller and a potential buyer of a selected property. A system receives input from a potential buyer indicating interest in a selected property. The system locates the property's address and determines the potential seller for the property. Contact is then initiated with the potential seller and the potential seller is provided with a code for accessing a dedicated communications channel with the potential buyer. Once the code is activated, the potential seller and the potential buyer can determine if there is enough interest to sell the property.

Abstract: In a solvent recycling system, a distillation vessel having an upper distillation zone and a lower waste collection zone and means whereby solvent waste falls into said waste collection zone before solvent enters said distillation zone. The system preferably has a solvent vapour outlet and a heating means, whereby solvent enters the vessel from above through the solvent feed inlet and solvent waste falls into said waste collection zone before distillation is commenced, and a shut-off means or filling tube extending below the distillation zone associated with the inlet to prevent solvent vapours exiting the vessel through the inlet during distillation.

Abstract: A parts cleaner for use in a process whereby solvent is preferred to always be available and is preferred to be as clean or pure as possible for use, comprising two containers respectively for clean solvent and for capture of used solvent or a single container having separate zones for clean and used solvent, said clean container having an outlet for supplying clean solvent for cleaning. The clean container may have an outlet for supplying clean solvent for cleaning and an inlet for clean recycled solvent, the used solvent container having an inlet for used solvent, an outlet for supplying used solvent for cleaning and an outlet for supplying used solvent for recycling. The used solvent container may have an outlet for supplying used solvent for cleaning and means for automatically switching between the outlets supplying said clean solvent and said used solvent for cleaning.

Abstract: An anti-pressure system for a vessel which is subject to internal pressure created by heating or boiling of its contents, the system comprising first and second spaced-apart outlets for vapour to exit the vessel, each outlet having a first side communicating with the vessel interior and a second side communicating with the vessel exterior. The invention provides a reliable method of protecting a normally un-pressurized vessel, such as an autoclave, distillation vessel, boiler or the like, from dangerous pressure build up, resulting from its vapour outlet being blocked, regardless of what other pressure release devices (if any) may be present on the vessel.
