Abstract: The dilution refrigerator operates by sucking a 4He-rich mixture from a tank and returning it to the tank through a superleak. Thereby the 3He is separated and returned to the 3He-rich content of the tank. By this cycling process, a drop in temperature is obtained at the exit of the superleak and through re-mixing of the 3He with the 4He. Cycling of the liquid 3He-4He mixture is performed by a bellows pump maintained in a container 16 at a temperature below 2 DEG K. and by specially designed valves comprising a steel ball as a plug and a gold ring as the valve seat.

Abstract: The vibration filter comprises an inner ring (27) on which vibration-sensitive equipment may be installed, the ring (27) being suspended from a plurality of springs (24, 25, 26) elastically supported by posts (18, 19, 20) in turn mounted on an outer ring (1) which is spring-suspended the same as the inner ring (27) from a rigid bench (8). The springs (12, 13, 14; 24, 25, 26) and other elastic members (9, 10, 11; 15, 16, 17; 21, 22, 23; 28, 29, 30) have differing resonant frequencies. Between the bench (8) and the outer ring (1), and between the outer and inner rings (1, 27) there may be provided eddy current brakes consisting of strong permanent magnets (46, 48) arranged opposite individual copper or aluminum blocks (5, 47).

Abstract: The travelling support (1) comprises a piezo-electric plate (2) resting on three legs (6) whose bottom surface is insulated from the bench (8) on which the support is to travel, by a dielectric (7). The piezo-electric plate (2) can be caused to contract by means of an actuating voltage applied via sliders (9, 10) to top and bottom electrodes on the plate (2). By applying a voltage to the legs (6), these may be clamped selectively by electrostatic forces effective across the dielectric (7). Appropriate control of the actuating and clamping voltages causes the support (1) to either move in a linear or rotary fashion. The displacements the support can perform per step are in the nanometer range.
