Abstract: Organic esters, to be employed to make up lubricating compositions are disclosed, said esters being the products of the reaction between a diol and a triol, on the one hand, and a mixture of saturated monocarboxylic acids, on the other hand. The ratios of the diol to the triol (molarly) and the structure and number of carbon atoms of the saturated monocarboxylic acids are critical. Critical values are given, as well as examples of practical use; the viscosity and viscosity index properties of the novel esters out do those of the conventional esters to a degree.

Abstract: A device is disclosed, which is intended for reducing the fuel consumption and the environmental pollution. An auxiliary power unit is provided, which is energized when a sensing mechanism signals to a signal-processing and control circuit that the engine is idling, for example, at a traffic light stop, or that a deceleration of the vehicle occurs. The fuel intake is cut off and a timing system provides to exclude the fuel feed to the engine for a certain selectable time. When such conditions are sensed, the auxiliary power unit (hydraulic or electric) provides to have the engine running without fuel use up. As normal traffic conditions are resumed, fuel is readmitted and the usual operation is started once again.

Abstract: Urea in powder, formed in the course of a prilling opration in which molten urea is delivered to a prilling tower adjacent its upper end for the formation of droplets which descend to the bottom of the prilling tower through a countercurrent stream of cooling air delivered to the prilling tower adjacent its lower end and which entrains that urea powder, is recovered by withdrawing the stream of air and urea powder from the upper end of the prilling tower and feeding it to an ejector connected with a collecting tank. Motive power is supplied to the ejector by feeding an aqueous liquid to it and that liquid transports the urea constituting the powder to a collecting tank from which the urea is recovered.
