Title: Improvements in or relating to star sensing system
IPC: G01S3/787
Filed: 1956-09-07
Abstract: 848,691. Photo-electric determination of direction. NORTH AMERICAN AVIATION Inc. Sept. 7, 1956, No. 27533/56. Class 40(3). In a system in which the output from a photoelectric cell is indicative of the deviation of the line of sight to a star from the axis of an optical system directing light from the star on to the cell, a rotating recticle interposed in the light path and modulating the starlight, transmits unmodulated the constant and constant gradient background light from the sky adjacent the star, as the centroid of the non-opaque portions of the reticle pattern falls upon the axis of rotation of the reticle. The telescope objective 2, Fig. 1, focuses light on to a P-E cell 3, a reticle 6 being rotated by motor 14 in the path of the light reaching the cell. In the first stage of operation the star image lies in the area 21, Fig. 2, of the reticle 6 and is chopped to give a cell output, selected by bandpass circuit 17, whose phase is compared in differential synchro 27 with a standard phase derived from an output of the same frequency from a generator 15 driven by the motor 14. The synchro 27 output is resolved into two orthogonal components, by the resolver 28, which are used to correct the angular orientation of the telescope so as to bring the star image towards the optical axis. The second stage of operation occurs when the star image fulls into the centre region 22, Fig. 3, of the reticle where the light chopping rate is doubled. The cell output frequency is then selected by band-pass circuit 18, Fig. 1, and operates relay 19 which energizes two rotary solenoids 9, 10. The solenoid 9 brings a deviation prism 4 into the optical system so that the star image is deflected to the peripheral portion 23 of the reticle. Simultaneously solenoid 10 rotates a shutter 5 to blank off portions 21, 22 of the reticle by an opaque portion 24 thereof. The third stage of operation is now effective. The light from the star image is now modulated by the pattern in the region 23 which consists of uniformly spaced radial strips superimposed upon uniformly spaced spiral strips. As shown, there are three spiral strips to every eleven radial strips, but other odd number ratios may be used. The phase of the modulation frequency in the output of cell 3 due to the spiral strips, and selected by band-pass circuit 25, is compared in differential synchro 29 with a standard phase, derived from a second output of generator 15. The synchro 29 operates a potentiometer 30 to give a voltage dependent upon the distance of the star image from the optical axis in its new position in area 23. Similarly the elements 26, 31, 32 energized by the cell output due to the radial strips provide a voltage dependent upon the direction of deviation from the optical axis of the line of sight to the star. These voltages are used to keep the telescope pointed to a given star continuously in a manner such as that described in Specification 833,400.

Title: Production of acetaldehyde
IPC: C07C45/30
Filed: 1966-06-23
Abstract: Preparation of acetaldehyde, and if desired vinyl acetate, by reacting ethylene at an ethylene pressure of up to 100 p.s.i.g. and at a temperature of 50 DEG  to 150 DEG  C. with a working solution comprising, in its oxidized state, acetic acid containing 0 to 20% by weight of water (based upon the weight of working solution), from 0.001 to 0.1 moles per litre of a palladium II salt, and at least 0.5 moles per litre of a zinc chloride/cupric acetate redox mixture, the mole ratio of Zn+2 to Cu+2 in said redox mixture being from 0.1 to 0.6:1.  The production of vinyl acetate is controlled by suitably adjusting the water content of the working solution. The process may be carried out batchwise or continuously in a single stage wherein ethylene and oxygen are simultaneously fed to the reactor and the working solution is drawn off continuously or intermittently for removal of the products.  Alternatively, in a two-stage process ethylene may be first passed through the oxidized working solution and the products are stripped from the spent working solution which is then oxidized with air or oxygen prior to being returned to the reaction zone.  In either method the water content of the working solution is maintained at the desired level by replacement of acetic acid or by conventional drying procedures.  The palladium II salt may be chloride, bromide or acetate or, preferably, an alkali metal chloro- or bromo-palladite although palladium metal, oxide or carbonate may be dissolved in the working solution.  The redox system consists of a mixture of zinc chloride and cupric acetate either as such or derived from suitable compounds in situ. The oxidation of ethylene to give acetaldehyde, vinyl acetate and a minor amount of ethylidene diacetate is carried out in a two-stage batchwise process wherein the ethylene pressure, the amount of water and the mole ratio of the redox system is varied and, also, in a continuous process.

[Also in Division H1] A piezo resistive semi-conductor strain gauge is attached to a bridge member which is in turn attached to the specimen whose strain is to be measured in order to partially compensate the non- linear strain-resistance characteristics of the gauge. Fig. 1 shows a strain guage 10 attached to a bridge 14 to measure the strain in a specimen 24, the gauge being prestressed by attaching it to the bridge member while the parts are at a temperature differing substantially from that at which the device is to be used, e.g. for measuring tensile stress an N-type semi-conductor can be attached to a duralumin bridge at a temperature of 125‹C. for use at room temperature, or to a molybdenum bridge at 780‹C. for operation at temperature of several hundred degrees C. Alternatively for compressive strain measurements a P-type semi-conductor may be attached to a duralumin bridge at temperature of minus 100‹C. for use at room temperature. Fig. 2 shows an arrangement in which a bridge 16 imparts a non-linear transfer characteristic between the strain in the member 24 and the strain transmitted to the gauge 10. The non- linearity in the transfer characteristic being arranged to be opposite in effect to the non-linearity of the gauge itself giving an overall linear characteristic. The gauge may also be prestressed as described with respect to Fig. 1. In addition two strain gauge elements of opposite conductivity type may be attached to the bridge member and arranged in adjacent arms of a bridge circuit to reduce the compensation required. Fig. 6 shows an arrangement in which gauges 10 connect in adjacent arms of a bridge circuit to measure the strain in specimen 60. The non-linear response of piezo resistive strain gauges with temperature variations may be compensated by the method described in Specification 950,937.
