Abstract: 1,116,065. Permanent data store. SOLARTRON ELECTRONIC GROUP Ltd. 20 Sept., 1966 [28 Sept., 1965], No. 41221/65. Heading G4A. A permanent digital data store includes a plurality of cores of magnetic material each having an electrical winding mounted thereon, a plurality of electrical conductors each forming all or part of a circuit either looping selected cores but not others, or looping some cores in one direction and others in the opposite direction, interrogation means for exciting at least one of the windings whereby information is obtained from the store by inducing an output signal in at least one other of the windings depending on the routing of the conductors, and response means for indicating when signals are induced in the other winding or windings. As described in one embodiment rods of linear ferromagnetic material pass through holes 22, 23, 24 (Fig. 4), or slots 25-29 in a plate 21 formed of conducting material, e.g. a plate of resin-bonded fibre-glass with a sheet of copper fixed to it, which may form a closed circuit around the holes or may have the circuit completed by a diode 31. Alternatively the conducting portion of the plate may be of the form shown in Fig. 5 with the portions enclosed in broken lines 46, 47 cut away to store a " 0 ". The magnetic rods form part of a closed circuit completed by a further rod parallel to the first and situated away from the plates, with a capping piece at each end joining the rods to complete the circuit. The second rod carries the interrogation or output windings. In operation flux pulses are introduced into the interrogation windings which induce a current in the appropriate plates. A " 1 " flux is of positive polarity while a a " 0" is of negative polarity of such a magnitude that the presence of a zero in one word will always give a negative current in entry plates other than the plate to be selected. The current in the plate then induces currents in the windings on the output rods. The process can be reversed with inputs to the output cores forming output pulses in the interrogation cores

Abstract: 1,180,329. Spin-drawing polyester filaments. FARBWERKE HOECHST A.G. 3 Sept., 1968 [31 Aug., 1967], No. 41851/68. Heading B5B. Filaments of a linear polyester are produced by a spin-drawing process which comprises spinning filaments of the linear polyester, preferably polyethylene terephthalate, subjecting them at a temperature within the range of from 10‹ to 120‹ C. to a permanent elongation corresponding to a value on that section of the stress-strain curve of the filaments in which the curve passes from a linear gradient to a section in which drawing takes place without a corresponding increase in the stress, and subsequently drawing the filaments. In a preferred embodiment, Fig. 2b, the apparatus comprises a spinning device, a delivery roller 2 which rotates at a rate which corresponds to the rate of spinning, and elongation- and draw-rollers, 9 and 7, in which the elongation roller 9 is a coaxial two-step roller whose diameter ratio corresponds to the ratio of elongation of the desired permanent elongation. The step roller is preferably heated to the drawing temperature, so that the elongation takes place at above the second order transition temperature of the filamentary material. If the step roller is not heated then the drawing is carried out between heated roller 7 and a following draw-off roller which draws the filament at a higher speed. In another embodiment the step roller is replaced by two rollers and the filament is preferably elongated between these two rollers when heated and is subsequently drawn over unheated roller 7. If one heated roller is omitted then the elongation takes place between unheated delivery roller 2 and the heated roller. In this case, the filament is elongated below the second order transition temperature.

Filed: 1974-10-01
Abstract: 1483077 Horizon sensor PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 1 Oct 1974 [4 Oct 1973] 42605/74 Heading H4D  In an horizon sensor for a geostationary satellite to sense its attitude relative to the earth an image I of the earth and the surrounding space is focused (lens 1) on to a plate P (n.b. Fig. 1 shows a sectional view and a "rear" plane view of the plate P). Positioned in the plate P on the "North South" and "East West" axes are four sets of horizon sensors each comprising, Fig. 2, an open square shaped aperture 231, a grating aperture 232 and two bolometers positioned behind slits 234, 233 (see also Fig. 4, not shown). Each set has a concave mirror not shown associated with it that is placed behind the plate P relative to the lens 1. The principal axis of each mirror (when stationary) passes through the centre "0" of its corresponding set. The radius of curvature of each mirror is such that the image of the aperture 231 is focused on the bolometer slit 233's plane and the image of grating aperture 232 is focused on the bolometer slit 234's plane. Each mirror is caused to rotate about an axis through a fixed predetermined angle so that the two images move up and down across the slits 233 or 234 in the North-South or East-West direction (depending on the set concerned). The output of the bolometer 233 consists Fig. 6 of a series of inverted pulses 62 whose duration PM or NS is proportional to the position of each space transition in the aperture 231 (under ideal conditions the earth-space transition is central). The output of the bolometer 234 is a sawtooth output 67. The two outputs are processed by a logic circuit (Fig. 5b, not shown) containing filters, threshold circuits and flip-flops. The logic circuit is such that the sawtooth signals of bolometer 234 are gated out during the square wave pulses 62, thereby providing a digital indication 68 of the position of the earth-space transition.
