Title: Method for controlling the energisation of the supporting and guiding electromagnets of a magnetically suspended vehicle
IPC: F16C39/06
Filed: 1972-08-29
Abstract: 1401313 Automatic control of position MESSERSCHMITT-BOLKOW-BLOHM GmbH 29 Aug 1972 [17 Sept 1971] 40054/72 Heading G3R A magnetically suspended vehicle, with four pairs of supporting and guiding magnets arranged symmetrically, is controlled by measuring parameters of eight air-gaps associated with the magnets, combining the measured values to produce five control signals for the position and attitude of the vehicle, and deriving eight voltage signals for feeding to the magnet coils. As shown, a vehicle 4 has supporting magnets 10, 11, 12, 13 and guiding magnets 20, 21, 22, 23 for co-operation with angle bars 40, 41 mounted on rails. Air-gaps S 1 -S 8  defined by each magnet are measured and corresponding signals fed to a circuit which averages and combines them to form values corresponding to lift, lateral thrust, roll, pitch and yaw of the vehicle. These values are fed separately through regulators, and the output signals are combined to produce voltages which are fed to the eight magnet coils so as to stabilize the vehicle position. By controlling each magnet in dependence on all the measured air-gaps, unequal magnetic forces due to variations in rail gauge and height are eliminated. In addition, further control voltages may be added to the magnet supplies in dependence on the magnetic force relationship to the gap size, coil current and coil resistance. These voltages ensure that the magnet fields produced are stabilized against gap variations.

Patent GB-949060-A (GB)
Title: Continuous treatment of molten steel
IPC: C21C5/56
Filed: 1960-11-22
Abstract: <PICT:0949060/C3/1> Steel is treated by a continuous process which comprises placing it in an open container, heating and circulating it by electrical induction, deoxidizing it with aluminium so that alumina formed is taken up by a supernatant slag and continuously passing the steel from the container through a duct shielding it from the air into a mould.  For example, molten steel 6 from a converter is poured, at a temperature 20 degrees below the normal temperature at the end of a converter heat, from a spout 3, and preferably in a stream of which one side is free, into a container 4 fitted with an electrical induction coil 10, where it is then heated and the aluminium and alloying addition,if any,are added continuously; alumina and other impurities come out in the supernatant slag 12 owing to the stirring action.  The container 4 is connected by the duct 14 to an auxiliary chamber 16 which is filled with an inert gas e.g. nitrogen or argon supplied from cylinders 17 through the dome 18 and ducts 22, 23, 24 and fitted with an outlet nozzle 27 whose bore 28 diverges and a metal stopper rod 32 fixed to a piston 35 and a rod 36, the latter being located in a cylinder 37 between the dome 18 and chamber 16.  Initially the stopper rod 32 is pressed downwards against the nozzle 27 by passing pressure fluid through the hole 44. To operate the flow of steel, the pressure of the inert gas is increased until the plug 9 is blown out of the hole 8, and the stopper rod 32 is raised by passing pressure fluid through the hole 45, the lower end of the nozzle 27 being below the level 30 of the liquid steel in the mould 31 to exclude air.

Abstract: 1,263,108. Displaying changes in a scene. E.M.I Ltd. 11 Aug., 1970 [13 Aug., 1969], No. 40386/69. Heading H4F. [Also in Divisions G1 and G4]  Apparatus for detecting changes in a field of view, e.g. the presence of flames or an intruder or a change in the reading of a meter, comprising means for exposing alternately the targets of two charge storage pick-up tubes to the area viewed to produce charges which are stored on said targets, means for scanning each of said targets and applying the signals derived therefrom synchronously to comparison means which produces an output signal when a change has occurred in said area viewed. In an embodiment, Fig. 2, pick-up tubes 1 and 2 are alternately exposed for fixed periods by means of shutters 8 and 9 respectively, to a viewing area, the pick-up tubes viewing the area by way of prisms 5 and 6, semi-reflective surface 7, and lens 4. After both the shutters 8 and 9 have been opened and closed the electron beams of the pick-up tubes 1 and 2 are allowed to scan the target and the output signals therefrom are fed in opposition to a differential amplifier (16, Fig. 2, not shown), which is connected to a detector device that sends a signal to an alarm device if the output of the differential amplifier is other than zero, or at least below a predetermined threshold value. Further embodiments are disclosed consisting of slow scan systems to view a bank of meters connected by telephone line to a remote monitoring station. When a change of reading is detected the output of the differential amplifier is combined with the output of one of the pick-up tubes to identify the meter concerned by giving it an increased brightness on the remote monitor. Alternatively the output of the differential amplifier only is transmitted and this is combined at the remote monitoring station with a locally produced television picture made from a photograph of the actual scene.

Abstract: 871,635. Pneumatic conveyers. EXPANDED PERLITE Ltd. Dec. 14, 1959 [Dec. 17, 1958], No. 40689/58. Class 78 (1). [Also in Group XXVIII] Insulating material is forced into an annular cavity surrounding a pipe 1 by injection from a pressure chamber 24. Pressure is supplied from a pump 50 (which may be replaced by a storage cylinder), a water trap 48, an air dryer 46, and control valve 43 to vents 37 in an annular orifice 36 leading from the chamber 24 via a pipe 39 to the chamber 3. The pipe 39 has a transparent section 40. A branch pipe from the main pressure source leads via a control-valve 56 to a nozzle 54 in alignment with the orifice 36. A tubular attachment 11 is secured to an aperture 5 at the other end of the pipe and forms a connection for a hessian bag 15. A conduit 12 leads via a control-valve 13 from the adaptor 11 to a suction device 60. In operation, the vessel 24 is filled from a hopper 58 and the cocks 43 are turned on and off, respectively. Material from the vessel 24 is thus injected into the chamber 3 until the bag 15 becomes filled. The bag 15 is then removed and a slide-plate 10 is closed over the hole 5. Both valves 43 and 56 are now opened and this completes the filling of the space 3. At the commencement of the operation material may be drawn in from the pressure chamber 24 under the action of the suction device 60. A seal 23 may then be removed and a further section of piping added for filling in the same manner.

Title: Seismic geophysical prospecting
Inventor: MUIR FRANCIS
IPC: G01V1/16
Filed: 1972-09-01
Abstract: 1400044 Seismic exploration CHEVRON RESEARCH CO 1 Sept 1972 [3 Sept 1971] 40759/72 Heading H4D  In a method of seismic exploration in which spaced seismic sources and/or geophones are used in groups to give a composite response signal per group whereby waves having undesired spatial frequencies can be suppressed, the groups are arranged along a survey line with intervals #e between the centres of adjacent groups and the individual sources and/or geophones are positioned within each group such that the group response-versus-spatial frequency function is substantially zero at the early integral or half-integral multiples of 1/#e. This has the effect of suppressing horizontally travelling coherent noise waves whose apparent horizontal wavelength is less than 2#e and which, therefore, are inadequately sampled by the use of groups at intervals #e. These noise waves would otherwise manifest themselves as false waves of greater apparent horizontal wavelength because of sampling ambiguity, i.e. would "alias" down to a lower apparent spatial frequency. In the Fig. 1 embodiment successive geophone groups 10, 11 are interleaved and their centres are at intervals #g(= #e). A suitable distribution of geophones within the group is derived by convolving the distribution within a sub-array of n geophones equi-spaced at intervals #g/n with the distribution within a second sub-array of m equi-spaced at intervals #g/m. For the example shown, m=2, n=3, so that, there are six geophones per group 10 or 11, the notional sub-arrays being represented at 10a, 11a, 10bl 11b. The resulting group response function is zero at integral multiples of 1/#g. By mixing the composite output signals of, e.g. three adjacent groups (resulting from actuation of a common source or common source group) after binomically weighting at 20, 21, 22 the composite signals, e.g. giving the composite signal of the centre group twice the weighting of the composite signal from the other two groups, the overall response function will be zero at multiples of 1/2#g. Alternatively a response function which is zero at multiples of 1/2#g can be obtained without the weighting and mixing process if the intervals within the sub-arrays are made 2#g/m and 2#g/n. The weighting and mixing may be done before or after recording the signals. Seismic sources 14 (e.g. electricallydriven vibrators) may be distributed in groups analogous to the geophone groups. In this ease the recorded output signals from a common geophone group, resulting from successive source group actuations, are weighted and mixed.

Title: A process for the resolution of dl-valine hydrohalide
Inventor: TATSUMI SUSUMU
Filed: 1962-10-29
Abstract: A DL-valine hydrohalide is resolved by preparing a substantially saturated or supersaturated solution of a DL-valine hydrohalide or of a mixture of a DL-valine hydrohalide and one of its enantiomorphs in a solvent in which the valine hydrohalide is soluble and from which it can be crystallised out, crystallising out an enantiomorph, if necessary (when no enantiomorph is initially present) or if desired (when the enantiomorph is present in the saturated or supersaturated solution) after adding seed crystal of the enantiomorph, and separating the crystals from the solution. The process may be repeated on the mother liquor. Suitable solvents are water, a C1- 5 alcohol, ethylene glycol monomethyl or monoethyl ether, an aqueous ketone solution, or an aqueous solution of an alkali metal halide of concentration below 35%.  The optically active valine hydrohalide obtained may be neutralised to obtain optically active valine.
