IPC: H04B7/185
Filed: 1964-01-03
Abstract: 1,081,841. Automatic attitude control. G. VALENSI. Jan. 3, 1964 [July 4, 1963; July 31, 1963; Aug. 22, 1963], No.46295/63. Heading G3R. In an automatic attitude control system for an orbiting satellite, photo-cells (px, p'x) Fig. 7a (not shown) situated at each end of the main axis (Ax, A'x) of the satellite receive signals, for example, from the earth, as the satellite rotates. The resulting voltages are applied to a comparator which produces a control signal to correct the position of the satellite if the difference between the two voltages differs from a predetermined value. Similar arrangements are provided for axes (By, B'y) and Cz, C'z). These control signals may be arranged to operate one or other of a pair of gas jets, to produce a pressure on the satellite envelope at the required point. In a further arrangement, Fig. 2 (not shown) a mass (M) attached to a spring (R) is movable within a tube (T). Normally the mass (M) is retained at the upper end of the tube by a finger (d) movable in a slot (t) of the tube. An error pulse causes electromagnetic (EL) to be energized and withdraw finger (d) so that the mass M is thrown by centrifugal force due to the rotation of the satellite towards the satellite envelope (Sa), spring (R) causing it to be returned. At this time electromagnet (ES) is energized for a short period so that mass (M) is drawn back to its rest position, electromagnet EL being de-energized to return finger (d). In an alternative arrangement, Fig. 4 (not shown) two oppositely rotating gyro rotors (T, T') of magnetic material are controlled by electromagnetic brakes (EF or EF') respectively in accordance with the correction to be applied.

In an absorption refrigeration system having a pump 52 for passing solution from the absorber 33 to the generator 10, a separation vessel 101 containing a packing material is arranged to receive solution discharged by the pump and separate non-condensable gases therefrom, said gases being collected in a storage vessel 105 communicating with the top of vessel 101 so as to provide a gas cushion which smooths pulsations in the flow of solution from the pump to reduce noise in the system. The pump may be of the reciprocating piston or hydraulically actuated diaphragm type. Part of the solution from vessel 101 passes through line 70, a rectifier 25, an analyser 18, a reservoir 17 and line 75 to the generator while the remainder of the solution passes through line 71, liquid heat exchanger 72 and line 73 to a conduit 15 which thus functions as a pre-analyser for vapour flowing from the generator to the analyser 18. The solution from conduit 15 enters reservoir 17 and is supplied to the generator 10 via line 75. The generator discharges to a separator 13 from which strong solution passes through line 80, heat-exchanger 72 and lines 81, 82, and 84 to the absorber. Any refrigerant vapour evolved from the heated weak solution in heat-exchanger 72 is added through line 94 to the vapour stream leaving the analyser. The absorber 33 comprises an upper header 34, a lower header 37 having an inlet 39 for solution from line 84, and a distribution pipe 40 in the lower header for refrigerant from the evaporator 29. Pipe 40 has apertures 41 arranged below some of the tubes interconnecting the headers so that a rising circulation of refrigerant and absorbent occurs in those tubes while absorbent descends in the remaining tubes. Header 34 communicates with a chamber 35 which supplies solution to the inlet of the pump and has a vapour outlet line 83 communicating with line 82. The packing in the separation vessel 101 may, as shown in Fig. 1, comprise four pads 109 of stainless steel wool or, as shown in Fig. 5, a plurality of wire mesh screens 509 mounted in a tubular body 512 located on the end of a vertical solution supply pipe 502.
