Title: Atomic Clocks with Spin Excahnge Collision
IPC: G01N24/00
Filed: 1966-07-29
Abstract: 1,152,685. Resonance cells. CSF-COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. 29 July, 1966 [4 Aug., 1965], No. 34298/66. Heading G6P. [Also in Division H3] An atomic clock comprises a resonance cell 2 containing two alkali elements X and Y, for example rubidium and potassium, the first of which is optically pumped by light from a source 1 including the first element X, and the second of which is excited by spin exchange collisions with atoms of the first element. One basic arrangement is shown in Fig. 2 wherein the output of a crystal oscillator 14 is multiplied in frequency by unit 12 and frequency modulated in unit 164 by the output of a sweep generator 163 before being fed to a resonant cavity 10 within which the cell 2 is located. The light from the source 1 passing through the cell is measured by a photo-cell 8 feeding an amplifier 161 and a phase comparator 162 which controls the frequency of oscillator 14. In Fig. 2, the cell 2 is subjected to the magnetic field of a coil 21 fed from a stabilized generator 22, the field being such that the derivative of the absorption frequency with respect to magnetic field is zero. In a modification, not illustrated, the magnetic field is zero so that the absorption frequency is independent of the magnetic quantum number m. In another arrangement, Fig. 4 (not shown), a second similar oscillator (15) is controlled by a second similar resonance cell (3), the absorption frequencies of the two cells being such that their sum is independent of ambient magnetic field. The outputs of the two oscillators (14 and 15) are fed to a mixer (18) which produces the sum frequency which is independent of the ambient magnetic field. In a further arrangement, Fig. 5 (not shown), the output of the modulator 164 is fed to a further modulator (19) where it is modulated, preferably in amplitude, to produce two sidebands which coincide with two absorption lines of the resonance cell. It is shown that the oscillator 14 is then locked to a frequency which is independent of magnetic field strength.

Title: An apparatus for the conversion of distance/angle variations into a coded output signal
Inventor: JAGER GERD
IPC: G01B9/02
Filed: 1968-07-18
Abstract: 1,239,830. Coding distance and angle variations photo-electrically. KOMBINAT NAGEMA VEB. July 18, 1968. No.34330/68. Heading G1A. Distance or angle variations are converted into digital output signals by converting them into angular movements of one glass plate relatively to another and investigating the interference in the wedge between the plates. Light from a monochromatic source 1 is collimated by a lens 2 and passes through the wedge 5, 6 to a projection system forming an image of the interference pattern in the plane of photo-conductive cells 4. The cells may be arranged to count fringes to provide incremental coding by using an oscillating optical system 3. Absolute coding may be provided by arranging the cells so that the numbers of fringes which pass them are in the same ratio as the light and dark areas on a conventional code strip. In order to provide cells which view the same part of the pattern but 90 degrees out of phase the spacing of the glass plates may increase steadily or in steps in a direction parallel to the axis of rotation of plate 5. A pair of wedges connected by reduction linkage may be used to provide coarse and fine indications.

Abstract: 1,171,659. Hydraulic reciprocating motors and pumps; engine turning gear. NEW YORK AIR BRAKE CO. Aug. 1, 1967 [Aug. 3, 1966], No. 35199/67. Headings F1A and F1K. In the engine starting and pumping system of Specification 1, 005, 679, comprising a hydraulic swash plate unit 13 with a valve assembly 37, 61 controlling movement of the swash plate by pistons 24, 29 and 35, for operation of the unit as a motor for starting the engine and then as a pump driven by the engine, severe oscillation of the swash plate between its pumping and motoring positions, when the engine fails to start and the accumulator empties, is avoided by the provision of a check valve 104 in the pressure supply line to the piston 57 which actuates valve assembly 37, 61. Check valve 104 acts to maintain piston 57 at full accumulator pressure to hold the swash plate in its motoring position until the engine starts and opens a speedresponsive switch 114 or, if the engine fails to start, when engine starting switch 113 is opened. Opening of either switch de-energizes the start valve solenoid 19a and also a solenoid 111 which releases a vent valve 107 to vent piston 57, and thereby move the swash plate to its pumping position. In other embodiments, Figs. 2 to 8 (not shown), the engine start valve is incorporated in the same housing as valves 104,107 and controlled by a pilot valve operated by the same solenoid as valve 107. A restriction may be provided in the start valve operating circuit so that full operating pressure is not developed in the motor until valve assembly 37, 61 has moved the swash plate to its motoring position, to prevent reverse rotation of the engine. Reference has been directed by the Comptroller to Specification 1, 005, 679.

Title: Purification of crude coke oven light oil
Filed: 1959-10-19
Abstract: <PICT:0876731/III/1> <PICT:0876731/III/2> Crude coke oven light oil is continuously purified by a process wherein a stream of the oil from tank 1 (Fig. 1) in turbulent flow is mixed in line 3 just prior to entry to treating coils 5 with sulphuric acid supplied by line 7 from tank 6 for a short time; on leaving coils 5 water is fed into line 14 just prior to the stream reaching coils 15 where most of the impurities previously extracted into the acid are extracted back into the oil.  On leaving coils 15, the stream passes to pressure decanter 17 the dilute acid passing therefrom by line 18 to storage tank 19, while the oil passes by line 21 and is mixed with ammonium hydroxide from tank 24 just before reaching coils 22.  On leaving coils 22, the stream passes to pressure decanter 27 where the liquids separate into 3 layers.  The upper oil layer leaves by line 33, while the two lower layers pass by line 28 to pressure decanter 29 where an upper layer of polymeric impurities separates and is passed by line 32 to be combined with similar polymers subsequently obtained, while the lower layer of annonium sulphate solution passes by line 31 to tank 19 for subsequent recovery of ammonia.  Just before the oil stream reaches coils 34 it is mixed with sufficient sodium hydroxide solution to effect complete neutralization, the neutral oil being separated off in pressure decanter 39 before being passed to steam still 43 by line 42. Stream-stripped oil passes from the still by line 45 to condenser 46 while neutral polymers leave the still by line 53 and are combined with the polymers from decanter 29.  The condensed liquids from condenser 46 pass to pressure decanter 48 where the neutral oil is separated from the water and passed by line 49 to tank 51.  This oil still contains some thiophene and this is removed by passing the oil by line 54 (Fig. 2) to line 55 where it is mixed with oleum fed by line 61 just prior to reaching coils 57.  The stream passes to pressure decanter 63 where acid is removed to storage by line 64, and the oil which separates is passed by line 65 to be mixed with further oleum entering by line 69 just before reaching coils 66.  The acid separated in pressure decanter 72 to which the mixture then passes is returned by line 73 to be used in the first oleum treating stage, while the oil is mixed in line 74, just before reaching coils 75, with enough sodium hydroxide to neutralize it.  Waste sodium hydroxide is run off from pressure decanter 81 while the resulting thiophene free light oil passes to tank 84 prior to being fractionated.  All the reactants fed into the main oil stream are fed in under a positive pressure of compressed air passed to the feed tanks by lines 8 and 58 so that the reactants are fed into the stream with a velocity 2-5 times that of the stream.  The time taken by the stream to pass through treating coils 5, 12, 22, 34, 57, 66, and 75 is preferably 5-60 seconds, and the reactants are generally fed into the main stream through fine orifices in directions transverse to the turbulent flow of oil.

[Also in Division H1] Crosspoint switch comprises a matrix of double injection diodes which are biased to a voltage level less than that required to make them conductive but are switched to their conductive state by incident light. The matrix of diodes may be formed on a common body of semi-conductor material (see Division H1). The light to turn on a diode may be derived by energizing the appropriate ones of an array of photo emitting diodes provided on one surface of a semi-conductor substrate which has the array of double injection diodes on its other surface or the light derived from an external source may be applied to the diode which is provided with a transparent or apertured electrode to allow the light access to the semiconductor material. Alternatively the light may be applied to the double injection diodes via light-conducting fibres, one end of each fibre being located adjacent a respective double injection diode and the other ends of the fibres being incorporated into a solid block of material. The end surfaces of the fibres incorporated in the block are coated with phosphor material and the block incorporated as the face of a cathode-ray tube. By appropriately indexing the cathode-ray beam the phosphor on the end of a fibre is caused to emit light which travels along the fibre to illuminate the respective double injection diode.
