Abstract: This invention relates to a gear shifting device for manual gearboxes. For gear shifting such gearboxes relatively great force is required, which the driver has to invest for every shifting operation. The shifting procedure, therefore, can be a very tiresome and exacting work for drivers of vehicles with manual gearboxes. In order to simplify and facilitate such shifting work, the present gear shifting device is equipped with a side position cylinder (2a,202) with a piston rod (11,203), which is connected to the shifter of the gearbox and movable to different predetermined positions for adjusting the shifter to a side position point corresponding to the selected gear, and a shift point cylinder (2b, 204) with a piston rod (14,205), which is connected to the shifter of the gearbox and movable to different positions for moving the shifter to a shift point corresponding to the selected gear by swinging the shifter in one direction or the other, and means are provided to prevent the movement of said piston rods until declutching has taken place and to prevent return of the clutch to traction position until the gear has been engaged in the gearbox.

Abstract: Separating device for separating the liquid components of a liquid mixture comprising an annular coalescing medium (84) for causing the liquid component to be removed from the mixture to coalesce into droplets, and a conical separating medium (102) tapering toward a liquid collecting sump (98). A heating element (46) heats the liquid mixture when the temperature of the mixture is below a predetermined temperature. An open, fibrous batt of filtering material (100) circumscribes the coalescing medium (84) to collect wax crystals which form during cold temperature conditions. A relief valve (108) permits liquid to bypass the separating medium (102) when the pressure differential across the separating medium (102) exceeds a predetermined amount. Accordingly, initial flow through the separating device is established, permitting the heater to heat the liquid to a temperature above that at which wax crystals form.
