Title: Improvements in or relating to methods of determining the ash content of coal
Inventor: GRAY ALAN LYLE
IPC: G01N33/22
Filed: 1960-02-05
Abstract: 960,408. Radio-active analysis of the ash content of coal. PLESSEY CO. Ltd. Feb. 10, 1961 [Feb. 5, 1960], No. 4128/60. Heading G1A. A method of determining the ash content of coal consists in the steps of irradiation of the coal by radio-active particles to produce the radioactive isotope of the material which produces the principal component of the ash content and of subsequently measuring the radio-active radiation emitted by the isotope. The coal 1 carried on a conveyer belt 2 is irradiated by neutrons from a vacuum type source or from radio-active sources 5 in a head 3 provided with a biological shield 4. The ash produces the isotope alumium 28 emitting gamma rays which are detected by scintillator material 8 surrounding the belt and producing light pulses operating one or more photo-multipliers 9 and circuits selective to the pulse amplitude for aluminium 28 to pass electric pulses to a rate motor and recorder 11 operated from a high tension unit 10. An alarm 12 or control device is operated when the output from the motor 11 exceeds a predetermined figure. A discrete sample of coal may be subjected to the radiation, and then examined at a spaced or seperated detecting unit.

Title: Improvements relating to Encapsulated Materials
Inventor: FLYNN EDWARD JOSEPH
IPC: B01J13/18
Filed: 1966-02-01
Abstract: 1,158,662. Granulating. DUNLOP CO. Ltd. 20 Jan., 1967 [1 Feb., 1966], No. 4285/66. Addition to 1,103,202. Heading B5A. [Also in Division C3] Apparatus is described for preparing droplets or capsules of epoxy resins for use in adhesives (see Division C3). The apparatus comprises means for producing droplets of the resin, a collector for the droplets and means for feeding a supply of BF 3  or a complex thereof along the walls of the collector and also a means for discharging the slurry of epoxy resin capsules and catalyst (BF 3 ) and means for recirculating the catalyst to the collector. The droplets may be formed using the spray head of Fig. I which comprises a cylinder 6 which is axially aligned with a rod-like member 7 tapering to a point 5 which forms an annular chamber 4 between the rod and the cylinder and provides an annular orifice 2. This assembly is mounted within a housing 1 in such a manner that a second annular orifice 3 is formed. In operation the resin passes through the annular chamber 4 and a gas, e.g. air under pressure is forced through the annular orifice 3, thus producing a spray of resin droplets which are then plunged into a bath of catalyst (BF 3 ) which forms a skin of cross-linked material on the surface of the droplets. A slurry of discrete particles of resin is thus produced in the collector which is subsequently separated from the catalyst liquid. In Fig. 3 (not shown), a circular spinning chamber is used to form a rotating spray head. This has orifices in its perimeter wall through which the resin droplets pass to the collector.

Title: Improvements relating to semi-reflecting optical devices
Inventor: ENNOS ANTHONY EDWARD
IPC: G02B27/10
Filed: 1960-02-10
Abstract: 898,714. Coating by vapour deposition. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Feb. 2, 1961 [Feb. 10, 1960], No. 4742/60. Class 82(2). [Also in Groups XX and XL(b)] A semi-reflecting optical device comprises a transparent base as of glass or plastic, having thereon a first layer of silicon monoxide, a second layer of silicon dioxide and a third layer of silicon monoxide, each layer having an optical thickness which is equal to onequarter of the mean wavelength of the light (e.g. 5500Š) with which the device is to be used. This device may be made by placing a glass base in an evacuated chamber and evaporating silicon monoxide from a tantalum container which is heated by the passage of a current therethrough. Thereafter oxygen is allowed to flow into the chamber and the silicon monoxide is again evaporated so that its vapour reacts with the oxygen to form a deposit of silicon diocide. A further layer of silicon monoxide is then deposited. The thickness of each layer is controlled photo-electrically. For this purpose, a monitor glass 1 is located in the chamber 2 adjacent to the surface of the transparent base member so that similar deposits are formed on surface 3 which is partially covered by a screen 4. Light from a source 7 is passed through a window 8 and reflected on to the monitor glass 1 and then through a window 9 to a photosensitive device 10. As the thickness of the silicon monoxide builds up, the output from the photosensitive device 10 increases to a maximum at which point the evaporation of silicon monoxide is cut off. When depositing silicon dioxide evaporation is cut off when the output from the photosensitive device decreases to a minimum. In an alternative a layer # inch thick is first deposited on a monitor glass and then vapour is allowed to fall thereon and on the transparent base member until a layer having the thickness of # inch is formed on the monitor glass.

Abstract: 1,041,921. Encapsulating a conductor. CIBA Ltd. Feb. 6, 1964 [Feb. 11, 1963], No. 5145/64. Heading B5A. A method of producing a filled cast resin body, e.g. an insulated high voltage conductor comprises the steps of putting a first coarse grained filler material into a casting mould and thereafter introducing a casting resin composition admixed with a second filler materal of finer grain. This ensures a higher overall volume percentage of filler. The mould comprising the conductor 1 and casing 5 is located in a vessel 14 filled with a cooling liquid. The coarse filler, e.g. a dried quartz sand mixture is placed in the mould cavity 2 which is then evacuated and filled under vacuum with a protective gas, e.g. CO 2  or other gas which is soluble in and/or reacts with the resin composition to ensure that the cast body is free of bubbles. The casting resin composition, e.g. an epoxy resin containing a hardening agent and a calcite filler is introduced into the cavity under pressure. The conductor 1 is heated and the valve 16 opened so that the level of cooling liquid falls, the composition setting from the centre of the cavity outwardly and from the top to the bottom.

Abstract: 1360737 Differential gears RHEINSTAHL AG 4 Feb 1972 [19 Feb 1971] 5248/72 Heading F2D A differential gear provided between an input shaft and two or more output shafts to driven wheel axles of a vehicle is so arranged that the ratio of the torques transmitted to each output shaft is the same as the ratio of the loads on each axle driven by said shafts. An input shaft 2 has a differential housing 4, with an interposed web 3, secured to its end 2a by bolts 5. Bolts 6 fixed between the housing 4 and web 3 mount bevel pinions 7 which connect bevel wheels 8, 9 on an output shaft 15 and a hollow concentric output shaft 10. The shaft 10 drives through equalizing gearing half shafts of a steerable axle while the inner shaft 15 drives through to a rigid axle and since the force on the two sides of the pinions 7 is equal, the torque transmitted to the shafts 15, 10 is proportional to the pitch diameter of the bevel wheels 8, 9 and the ratio between the torque and thus the diameters is arranged to equal the ratio between the loads on the axles. If three driven shafts are provided the shaft 15 drives through a similar differential to the second and third axles.
