Title: Gyroscopic north-seeking apparatus
IPC: G01C19/38
Filed: 1972-06-23
Abstract: 1400488 Gyroscopes: measuring angular position photo-electrically SOCIETE DE FABRICATION D'INSTRUMENTS DE MESURE 23 June 1972 [23 June 1971] 29507/72 Addition to 1224992 Headings G1A and G1C An improvement in or modification to a gyroscopic north seeking device disclosed in parent Specification 1224992 comprises a system for improving the immunity of the equipment to errors caused by parasitic motion, i.e. swinging, of a pendular assembly, i.e. a horizontal rotor suspended by a vertical ribbon, which motion could cause errors when determining by an algebraic calculatory method the meridian axis about which the assembly is oscillating. A disc 6 having graduations thereon, is attached to the rotor and oscillates therewith. The graduations on the disc 6 when so moving, pass between oppositely positioned pairs of luminescent diodes 10A, 10B and 11C, 11D modulated at different frequencies and photoelectric detectors thereby producing signals which when amplified and filtered undergo processing in logic circuits to produce logic signals which are indicative of the sense of rotation of the disc 6 at the diametrically opposite pick-up points. These signals are added if the senses are the same, corresponding to true rotation, or subtracted if they are opposed, corresponding to anomolous swinging motion. In this manner, the number of graduations passing the diode pairs 10A, 10B and 11C, 11D is counted during a half cycle of rotor oscillation. Triggering of the counting period is accomplished by a third pair of luminescent diodes 10E, 11F which detect opaque/transparent (O/T) transitions 51, 53 or transparent/opaque (T/O) transitions 52, 54 on ring 50. When opposed transitions 51, 53 or 52, 54 coincide, which occurs when swinging is absent, graduation counting starts and a subtraction counting operation is triggered. A subtraction counter circuit is associated with a clock signal generator in which has been introduced a predetermined value of the half period of rotor oscillation. Graduation counting is terminated when the subtraction counting circuit has zero output. The influence of geographical latitude on the operation of the apparatus is minimized by reducing the torsion in the rotor suspending ribbon which reduces to zero a term having latitude dependence. The ribbon is suspended from a motor rotor which is rotated in response to the logic signals directly or via a separate logic system. Suitable reduction gearing ensures minimal torsion. Visual or electrical means also enables rotor caging and uncaging when torsion in the ribbon is absent.

Title: Porous supports for chromatography
IPC: B01D39/00
Filed: 1968-06-20
Abstract: 1,236,761. Chromatographic packings. E.I. DU PONT DE NEMOURS & CO. 20 June, 1968 [20 June, 1967], No. 29566/68. Headings B1L and B1X. A packing material of use in either gas or liquid chromatography comprises an impervious macroscopic substrate coated with a plurality of like monolayers of colloidal inorganic microparticles which have the same charge and similar, but not necessarily identical, chemical composition, and which are joined to the substrate by electrostatic forces. Although crystals, granules, and glass wool may be used, the preferred substrate is glass beads with diameters of 25-250Á. The microparticles electrostatically bound to such substrates suitably have a size in the range 0.005-1Á, and may for example be iron oxide, alumina, thoria, titania, zirconia and aluminosilicate clays, although silica is preferred. After coating the substrate with a monolayer of microparticles by immersion in a suitably charged colloidal sol thereof, the coated substrate is treated with a solution of an oppositely charged organic material, e.g. a gum, latex, protein, polymer or surfactant, so that a further layer of microparticle is electrostatically bound by reimmersion of the substrate in the charged sol. This sequence of steps is repeated as desired, but preferably until the coating comprises 0.002-25% of the total volume of the packing. The packings may be used in conjunction with a liquid stationary phase.

Abstract: 927,607. Aircraft undercarriage controls. DOWTY ROTOL Ltd. Aug. 25, 1961 [Aug. 29, 1960], No. 29743/60. Class 4. A fluid pressure-operated system has two normally separate fluid circuits, each containing a pressure source 13, a motor 20, a selector valve 17, a pressure sensitive device 38 and a time delay device 40 which, on pressure falling below a predetermined value in one circuit, after a predetermined time, causes operation of emergency valve 27 to connect motor 20 of that circuit with the source 13<SP>1</SP> of the other circuit. As applied to aircraft, contraction of motor (in jacks) 20, 20<SP>1</SP> retracts the undercarriage; a switch 35b is closed to energize coils 33b, 33b<SP>1</SP> to move valves 16, 16<SP>1</SP> so that operation of pumps 13, 13<SP>1</SP> delivers fluid to chambers 24, 24<SP>1</SP> of the jacks, fluid exhausting from chambers 21, 21<SP>1</SP> to tanks 11, 11<SP>1</SP> via valves 19, 19<SP>1</SP>, 16, 16<SP>1</SP>.

If a failure occurs in the electric circuits, then closure of emergency switches 41, 41<SP>1</SP> operates valves 26, 26<SP>1</SP> so that pumps 13, 13<SP>1</SP> are connected to jacks 20<SP>1</SP>, 20, by-passing time delay devices 40, 40<SP>1</SP>.

Patent GB-298896-A (GB)
Abstract: 298,896. Bogdandy, S. von, and Wamoscher, L. Oct. 15, 1927, [Convention date]. Low-pressure metallic-vapour apparatus.-In a closed mercuryvapour lamp having a longitudinal division wall, a substantial part of the transference of heat to the cathode takes place through the division wall from the vapour of the arc, such transference resulting from the small amounts of metal employed as electrodes. The envelope consists of a sealed quartz tube 1 through the lower end of which pass tungsten leads 2, 3 surrounded by quartz tubes 4. Fused into the tube 1 so as to divide it longitudinally except at the upper end, is a quartz partition 5, the lead in wires being placed one on each side of the partition and situated close to the wall of the tube 1. Small amounts of mercury are contained in the lower parts of the tube, the position of the wires 2, 3 ensuring that contact will be maintained when the tube is tilted, to strike the arc, in the plane of the partition and towards the lead-in wires. The top of the partition is protected from undue heating by a thirkening 9 or a coating of refractory metal such as tungsten. When the arc is struck, the tube is returned to the upright position and after a short time a difference of level a b is produced between the anode 6 and the cathode 7, the arc 8 lying close to the cathode mercury along the surface a, b and thus heating it. To reduce the amount of mercury employed, the cross section of the cathode chamber may be made smaller than that of the anode at the surface of the electrode, or the capacity of the cathode chamber may be reduced by sloping the partition towards the lower end of the chamber. When a cooling fluid is employed, this is preferably led round the tubes 4 and then through a jacket surrounding the lamp; the jacket may be constructed so that condensed mercury vapour falls back to the anode. Instead of being evacuated the lamp may contain rare gases. The Specification as open to inspection under Sect. 91 (3) (a) states that mercury may be replaced-by another metal. This subject-matter does not appear in the Specification as accepted.
