Abstract: There is described a servo-control system incorporating a double-acting ram which is responsible for compensating electro-hydraulically for the imbalance in a servo-controlled load in order to achieve a high performance. To this end, a compensating loop is produced which slaves a balancing pressure P.sub.e to the variations in the imbalance. This pressure is exerted in one of the chambers of the ram, separately from the control pressure. It is governed by a pneumatic accumulator whose load is a function of the lack of balance between the pressure exerted by the imbalance and the balancing pressure.

Abstract: A power generator utilizing the full volumetric expansion of water upon its change from the liquid phase to the solid phase (ice). The generator includes a chamber having heat transmitting, fluid impervious, flexible walls. The chamber is filled with water. A pressure-containing housing has an internal cavity in which the chamber is located in spaced relation to the housing. The space between the housing and the flexible walls of the chamber is filled with a fluid which is circulated through the cavity. A conduit connected to the housing provides flow communication between the cavity and means for utilizing moving fluid, such as a fluid driven motor. The phase of the water in the chamber is changed from liquid to solid so that the water expands in volume. Expansion of the water expands the flexible walls of the chamber to displace a proportional amount of fluid from the housing through the conduit, the moving displaced fluid serving as a power medium to drive the motor to do work.

Abstract: A servo-assisted hydraulic master cylinder has a variable ratio effect so that brake fluid is initially displaced to the brakes at a high rate with respect to driver pedal movement and then at a low rate when an appropriate pressure has developed. A stepped piston assembly comprising a first piston slidable in a second piston defines a first chamber which is directly connected to the brakes and a second chamber in which a variable pressure is developed. The first piston is operated directly by the pedal through the servo valve and is subject only to brake pressure in the first chamber so that brake pressure is proportional to driver effort during normal operation. The second piston is operated by the servo diaphragm through the servo valve housing.
