Patent GB-694842-A (GB)
Abstract: 694,842. Electric variable condensers. HONORE, E. A. H., TORCHEUX, E. L. G., ROY, R. D. C., and MACHINES AUTOMATIQUES BARDET. Dec. 27, 1951 [Dec. 27, 1950], No. 30239/51. Class 37. A variable condenser comprises two concentric cylinders 1, 2, Fig. 1, of insulating material having condenser plates on their facing surfaces, each cylinder having at least two accurately ground bearings 4, 4a, and 3, 3a, between which are located hollow, cylindrical, elastically deformible rollers 6 whose diameter is slightly greater than the distance between the bearings 3, 4. Terminals 11 pass through the cylinder 2 to make contact with the condenser plate on its inner surface; terminals 12, preferably spring loaded, pass through the cylinder 2 to make contact with the condenser plates on cylinder 1. Preferably solid, cylindrical, non-elastic rollers alternate with the rollers 6 and are of diameter slightly less than the distance between the condenser plates 3, 4. The outer cylinder may bear two condenser plates 15, 16, Fig. 3, and the inner cylinder may also bear two plates 20, 21, Fig. 5, so that as one capacity increases the other decreases. The outer cylinder may have its plates shaped to any desired law, Fig. 7 and the inner cylinder have e.g. four plates 29 ... 32, Fig. 8, to provide any desired relation between capacitance and rotation. To compensate for any eccentricity, the cylinders may bear a plurality of plates, those disposed at 180 degrees on each cylinder being connected together.

Title: Stowage compartment for solar cell array
IPC: B64G1/64
Filed: 1978-07-24
Abstract: A flexible cover comprising a sheet of lightweight material 3 encloses a solar cell array 5 stowed in concertina- like folds. Light alloy strips 10 bonded to opposite edges of the sheet 3 carry catches 30a, 30b serving to hold the edges together to form a generally tube-like container. A series of flat springs 4 are also attached to the edges of the sheet to draw them apart when the catches are released so as not to impede release of the contents. The catches each comprise a pair of heads held together by a locking plate 11 and all locking plates are linked with a release mechanism which includes a pyrotechnic device. Operation of the release mechanism frees the locking plates, which are biassed towards their disengaged position, allowing the container to open. An inflatable bag 6 within the container acts to support the solar cell array and may assist in the opening of the container. Secondary release means comprises electrical resistance wires arranged to melt the cover material so as to free the container contents. <IMAGE>

Title: Normally closed valve assembly
IPC: F15B11/05
Filed: 1979-09-28
Abstract: A modulating two stage valve and compensator assembly comprises a first stage poppet 23 movable between a normally closed state seating in a first stage orifice 25a and an open state, for controlling flow of fluid through a passage 25e-25g in a second stage poppet 25. The poppet 25 moves between an open state and a closed state seating in and closing a second stage orifice 35a when the first stage poppet 23 is in the normally closed state thereby to prevent any substantial flow of fluid through the first and second orifices. Electromagnetic means has applied thereto a predetermined value electrical signal for moving the first stage poppet 23 to an open position related to the value of the electrical signal. The resultant drop in pressure behind the second stage poppet 25 causes it to move to a position which is a function of that signal value. The end 12b of a fixed core of the electromagnet is recessed to receive an armature 20 attached to the poppet 23 and has a cross- section which tapers towards the poppet. <IMAGE>
