Title: Wet separating
IPC: B03B5/42
Filed: 1979-01-09
Abstract: A rotatable separator barrel for the wet separation of solids, e.g. coal and shale into three fractions, has opposed end portions 11, 12 each with a respective annular weir-forming baffle 16(17), and a helical scroll 14(15) disposed to transport solids to a central zone 13. The central zone 13 is divided into two parts 20, 21 by an annular baffle 22 which prevents spilling over between bodies of water 18 contained between the end baffles 16, 17 and the dividing baffle 22. A loading chute 19 is arranged to discharge solids to be separated into the end portion 12, while in each part of the central zone, a chute 25(28) is arranged to catch solids lifted up by scoops 23(26) on the barrel wall. The chute 25 in the first part 21 directs solids to the end portion 11, whilst the chute 28 in the second part 20 is arranged to discharge solids from the barrel. Thus a first output of suspended solids is provided over the first end baffle 17, a second output of suspended solids over the second end baffle 16, and an output of sediment from the second chute 28. <IMAGE>
Patent GB-2017179-A (GB)
Title: Textile Treatment Process
IPC: D06B3/04
Filed: 1979-02-02
Abstract: Substantive synthetic resins are applied to textile fibrous materials, e.g. wool sliver, yarn or fabric, by continuously passing the material and an aqueous solution or dispersion of the resin through a tubular reactor and adjusting the relative speeds of the material and the liquid so that the material has taken up the desired amount of resin when it leaves the reactor and the discharged liquid is substantially depleted of resin. Improved results can be obtained by preliminary oxidative treatment, e.g. with chlorine water, which can also be carried out in a similar tubular reactor. Preferred pH values are 2-2.5 for the chlorination and 7.5-8.0 for the application of a polyamide/ epichlorohydrin resin to wool. The process is particularly suitable for shrink-resist treatment of wool.

Title: Cryostat with radiation shield
IPC: F25D19/00
Filed: 1979-02-15
Abstract: An improved cryostat for the superconducting magnet (50) of an NMR spectrometer comprises a nested structure of isothermal shells (112,114,116) surrounding a thermally conductive central reservoir (110) of substantially spherical shape containing liquid helium in which the superconducting solenoid remains operational when only partially immersed. A radiation shield (112) surrounding the central reservoir is cooled by the boil-off of escaping helium vapor. The radiation shield is enclosed within an isothermal shell (114) maintained at the temperature of liquid nitrogen by thermal contact with a liquid nitrogen reservoir (114') disposed above the region of the central reservoir and shielded therefrom by a wall of the isothermal shell. An outer radiation shield (116) surrounds the liquid nitrogen reservoir and associated isothermal shell and the outer radiation shield is maintained at a constant temperature. A hermetically sealed containment vessel (118) forms the outer wall of the cryostat and provides a port for evacuating to a very low common pressure all the interior spaces between adjacent nested structures. <IMAGE>

Patent GB-2043328-A (GB)
Title: Multi-tubular battery plates
IPC: H01M4/76
Filed: 1979-03-09
Abstract: A multi-tubular battery plate comprises a plurality of tubes containing active material and a conductive spine extending along its length.

Patent GB-2026891-A (GB)
Title: Degassing liquids under reduced pressure
IPC: A01J11/04
Filed: 1979-08-01
Abstract: In a method and apparatus for degassing a confined volume of liquid, e.g. milk, to be measured during the transportation of the liquid from a first vessel (not shown) to a second vessel 8 via a gas separation vessel 1 and a volumeter 7, degassing is promoted by regulating the supply to, and discharge from, the degassing vessel dependent on a subatmospheric pressure to be maintained therein. A liquid level sensor 13 causes valve 11 to open and valve 6 to close if the liquid level falls, thereby drawing air out of the space 15 via pump 7 and drawing more liquid through pipe 3; then closes valve 11 and opens valve 6 to allow the liquid to be transferred via pump 7 to tank 8. Special arrangements using time switches are utilised at the beginning and end of a run. <IMAGE>
Patent GB-2066648-A (GB)
Title: Air-dilution cigarette filter
IPC: A24D3/02
Filed: 1979-10-01
Abstract: The filter of the cigarette is provided with an annular peripheral on groove to enable air to pass directly into the fibrous body of the filter material after passing through apertures in the tipping paper. Use is made of ordinary plug wrap paper instead of a high porosity tea bag paper to wrap the fibrous filter material. The annular groove can be formed by a pair of rotating knives and a rotatable spacer with radial cutting edges which rout out material from each filter plug during conveyance of the plug on an alignment drum of a cigarette making machine. Alternatively, a plurality of closely spaced rotating knives which cut through the plug wrap paper only may be used to form a series of closely spaced annular grooves or slits in the filter periphery. <IMAGE>

Patent GB-2070807-A (GB)
Title: Temperature stabilization system for measuring apparatus
IPC: G05D23/24
Filed: 1980-01-31
Abstract: A radiation detector (36) (Figure 2) is housed in a chamber (20a) in a heat conductor (20) which is positioned in a dewar flask (34). A thermo-electric cooler (26) is joined to one end of the heat conductor and a fin heat dissipation device (28,30) is joined to the cooler. A thermistor (24) senses the temperature of the heat conductor. Control means (52) respond to the sensed temperature to operate the cooler to remove heat to stabilize the temperature of the chamber. The assembly extends into a conduit (12) through which flows material, radiation from which is to be detected, the fin assembly (28,30) being exposed to the atmosphere. The detector (36), e.g. a scintillation crystal and a photomultiplier perform better at the stabilized temperature, which may be less than that of the flowing material such as warm oil. <IMAGE>
