Abstract: 1480652 Automatic control of gyroscopes GENERAL ELECTRIC CO 30 Dec 1974 [2 Jan 1974] 56051/74 Heading G3R An inertial guidance system for an aircraft includes a directional reference gyroscope 1 and a vertical gyroscope 5 which are slaved under normal conditions to magnetic compass 2 and gravity sensor 6 respectively. If the aircraft turns rapidly both the magnetic compass and gravity sensor will become subject to dynamic errors which would be reflected by the slaving circuitry into the platform and thus it is necessary to disable the slaving circuit by means of relay systems 4 and 8 when the rate of turn exceeds a predetermined level. The angular position of the azimuth axis gimbal of gyroscope 1 is measured by a control transmitter (synchro) 35 and the output signal on lines 36 passed through differential transformer 37 to converter 90 which produces signals proportional to the sine and cosine of its input signal. The sine and cosine signals are demodulated and differentiated to produce signals proportional to the speed of the shaft 34 which signals are summed vectorially at 100 and if the resultant signal level exceeds the reference level applied to comparator 10 relay coil 80 is energized to cut off the supply to relay coil 61 which interrupts at contacts 59, 60 the signal from amplifier 54 to torquer 56 on gyroscope 1. Additionally the connection to torquer 73 of gyroscope 5 is broken at contact 79 so both the gyroscopes operate freely for the duration of the turn. In modifications the Scott-Tee converter 90 may be replaced by a transolver which produces the sine and cosine signals directly or, alternatively, the three wire output of resolver 37 may be demodulated and differentiated and summed algebraically to obtain a third signal to add to the vector summation, Fig. 6 (not shown). The positional signals can be derived from the heading shaft 34 itself or alternatively from an intermediate stage of the heading shaft drive gearing 49, Fig. 5 (not shown).

A melt extruded sheet material comprises lamellµ of a first material, which is polymeric, and lamellµ of a second, different, material, the lamellµ of the first and second materials being interspersed with each other and intimately adhering to one another, each lamella of the first material traversing part at least of the thickness of the sheet material and being, over at least a substantial part of its surface area, between 0À1 micron and 10 microns in thickness and at an angle of less than 2 degrees to the surface of the sheet material. The lamellµ may be 8-shaped in cross-section transverse to the length direction of the sheet material. The lamellµ may be J-shaped in cross-section along the length direction of the sheet material. The sheet material may comprise at least one further extrudable material interspersed with the lamellµ of the first and second materials and may be an adhesive bonding the first and second materials together. The second material may be polymeric and the adhesive may comprise a mixture of the principal polymeric components of the first and second polymeric materials. The second material may be a powder of inorganic material. The first material may be polyethylene and the second material cellular polystyrene, the two materials being united through interposed lamellµ of an adhesive material. The sheet material of the invention may be made by melt extruding the first and second materials through an annular die such as that shown diagrammatically in perspective view, partly in section, in Fig. 4 of the drawings. The device shown in Fig. 4 comprises an annular row of feed slots 3 for the first material alternating with an annular row of feed slots 4 for the second material above which is an annular collecting chamber having walls 5 and 6 which converge to an annular extrusion slot. The walls 5 and 6 may be rotated together relatively to the row of feed slots 3 and 4 whereby the drag exerted by the bottom of the collecting chamber on the lamellµ formed by the simultaneous feeding of the melts 1 and 2 through the slots 3 and 4 into the collecting chamber, the passage of the melts through the latter and their simultaneous extrusion through the annular slot at the top of the collecting chamber produces a shearing effect. The tube or tubular film of the laminated first and second materials thereby produced has the lamellar structure imparted to it which is characteristic of the sheet material of the invention. The melt extruded sheet material is cooled and solidified in the usual manner and thereafter may be longitudinally slit to the " lay flat form ".

Abstract: 1404970 Distilling hydrocarbons NIPPON ZEON CO Ltd 22 Dec 1972 [27 Dec 1971 14 Jan 1972] 59528/72 Heading C5E Cyclopentadiene (CPD) is separated from cyclopentene (CPE), or from 1 : 3-pentadiene (PPL), or from both by azeotropic distillation with n-pentane; the azeotrope of cyclopentadiene and n-pentane boils at a lower temperature than any of the simple hydrocarbons. A ternary mixture of CPD, CPE and PPL is separated by successive steps of azeotropic distillation as above and extractive distillation. Either the CPD is first removed by azeotropic distillation, and the CPE and PPL separated from one another by extractive distillation, or the CPE together with a small proportion of the CPD is first separated from the PPL and the bulk of the CPD by extractive distillation, and the PPL or both fractions then freed of CPD by azeotropic distillation. In either case, if acetylenes are present they will be recovered in the PPL fraction, or can be removed from it by a second extractive distillation, or as a side-stream in the stripping of the extract from the first extractive distillation, or by hydrogenation. The components of the azeotrope may be separated by heating to dimerize the cyclopentadiene, separating the dimer from n-pentane by distillation, and then depolymerizing. The dimer may be separated from the n-pentane by recycling their mixture to the azeotropic distillation. The n-pentane may be supplied as a hydrocarbon mixture containing n-pentane, and may be mixed with the feed before it is distilled, or introduced separately to the middle or lower part of the fractionation column. Specific applications are: (1) a C 5  by-product fraction from hydrocarbon cracking, comprising CPD, isoprene, PPL and CPE (a) is heated to dimerize most of the CPD, (b) the mixture is distilled to a cut point of 50‹ C., (c) the distillate is extracted or extractively distilled to obtain a mixture of isoprene, PPL, CPE and residual CPD, (d) isoprene is removed by distillation, and (e) the residue then sent to the azeotropic distillation; (2) a similar mixture obtained by dehydrogenation of pentanes or pentenes is subjected to steps (c), (d) and (e) of application (1); (3) a C 5 -mixture is distilled to a cut point of 40‹ C., most of the CPD is dimerized by heating, the product distilled to a cut point of 50‹ C., and the distillate from this last step sent to the azeotropic distillation; (4) CPD is partially hydrogenated to a mixture of CPE and CPD, which goes to the azeotropic distillation.
