A safety system for a masted lift truck comprises an hydraulic connection between the hydrualic rear suspension of the truck and control valves in the hydraulic circuits of the lift and mast-tilt rams whereby lifting of the load carriage and forward tilting of the mast is prevented when the load on the rear wheels falls below a predetermined value. As shown, valves 56 in the two circuits comprise non-return valve members 57 and pistons 59 in cylinders 62 which are connected to the cylinders 13 of the hydraulic rear suspension. When the pressure in the cylinders 13 falls below a predetermined value, when the truck is in danger of overturning, the pressure in the cylinders 62 is not sufficient to hold the non-return valves open, by means of projections 61 on the pistons 59, and flow of fluid through the control valves 36, 37 to extend the tilt and lift rams 27, 24 is thereby prevented. The rams may be retracted by flow of fluid from the rams through the non-return valves to the reservoir 39. In a modification, Fig. 3 (not shown), the valves 56 are actuated by electromagnets connected in a circuit including a pressure-actuated switch connected to the hydraulic suspension.

Abstract: A component liquid in a mixture of liquids is separated therefrom by first heating the mixture to a certain temperature in heat exchanger 4 and then spraying the heated mixture through nozzles 11 into a vacuum chamber 5. The temperature to which the mixture is heated is determined by obtaining the boiling points of the liquid components in the mixture at the reduced pressure of the vacuum chamber, and then selecting the temperature so that this is above the boiling point of the liquid to be separated but below the boiling point of the other liquid or liquids at the reduced pressure. When the heated mixture is sprayed into the vacuum chamber, the liquid with the low temperature boiling point vapourises and can be drawn off as vapour and condensed in chamber 12. <IMAGE>
