Title: Improvements in or relating to the production of composite yarns, cords, braids, fabrics and similar textile products
IPC: D02G3/40
Filed: 1941-09-19
Abstract: 552,130. Yarns and threads. BRITISH CELANESE, Ltd. Sept. 19, 1941, No. 12077. Convention date, April 2. [Class 120 (iii)] [Also in Group IV] Yarns or fibres of a thermoplastic material are associated with yarns or fibres of a relatively non- thermoplastic material to form a composite yarn, cord, braid or like textile product which is then subjected to the action of vapours of a softening agent for the thermoplastic material so that without stretching the yarn or subjecting it to lateral compression, the thermoplastic material is caused to soften and to bond together the non-thermoplastic yarns or fibres. The thermoplastic material may be a cellulose derivative, a polyvinyl compound or a synthetic linear polyamide. The non-thermoplastic yarns may be of cotton, linen, silk, regenerated cellulose, or of stretched and then saponified cellulose esters, or they may be made of staple fibres having a basis of a cellulose derivative or linear polyamide, blended with non- thermoplastic fibres to give a yarn which is in part thermoplastic. Yarns of non-thermoplastic material may be wound or braided about a core yarn of a thermoplastic material or the core may comprise non-thermoplastic textile material which has wound about it a thermoplastic yarn and the remaining non-thermoplastic yarns may be twisted or braided about the core yarn. Both core and windings may comprise yarns made by spinning a mixture of cotton fibres and cellulose acetate staple fibres. The thermoplastic yarns or fibres may be treated with a plasticizer prior to being twisted or associated with the non-thermoplastic yarns, or the composite yarn may be treated with a plasticizer e.g. an emulsion or solution of methoxy ethyl phthalate, triethylene glycol, ethyl phthallyl ethyl glycollate, B-trichlorethyl phosphate, or ethyl-p-toluene sulphonamide. The plasticized yarn may be aged to ensure proper penetration of the plasticizer. The solvent or softener may be acetone, acetone and water, ethyl alcohol, diacetone alchohol, ethylene dichloride, chloroform, methyl chloride and methyl or ethyl alcohol, or dichlorethylene. In an example, a cellulose acetate yarn is wound about a cotton yarn to form a core yarn. Several cotton yarns are twisted about this core yarn to form the composite yarn which is then subjected to treatment with warm acetone vapour to coalesce the cellulose acetate yarns and bond the assembly into a compact unitary structure. In another example the composite yarn comprises several stretched saponified cellulose acetate yarns braided about a core yarn of cellulose acetate.

Title: Fluid interface detector
Inventor: MORRISON ALEXANDER INGRAM
Filed: 1962-03-29
Abstract: 970,134. Detecting fluid interfaces electrically. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. March 19, 1963 [March 29, 1962], No. 12079/62. Heading G1N. A fluid interface detector includes a probe and means for reciprocating the probe through fluid interfaces, the probe including a heated resistor which actuates a relay when the probe passes between fluids of different thermal conductivities, and a unit sensitive to electrical conductivity which activates a second relay when the probe passes between fluids of different electrical conductivities, means being provided for indicating the position of the probe. The resistance of a thermistor 11 controls a relay 42 in the emitter-collector circuit of a transistor 45. The resistance between conductors 16, 18 controls second relay 43 in the emitter-collector circuit of a second transistor 49. Motor 26 for reciprocating the probe has an "upward" winding 28, a "downward" winding 27, and a brake winding 29. A slider attached to the probe moves over a resistor 25 connected in a bridge circuit so that meter 56 indicates the height of the probe. The probe is initially moved to its lowest position by selecting contact 66 of a rotary switch 59. At the lowest position limit switch contacts 32 are closed and lamp 71 is lit. The meter zero is adjusted by resistor 57. Contact 63 is then selected to drive the probe to its uppermost position, closing contacts 31 and lighting lamp 67. The meter is scaled by adjusting resistor 58. While the probe is in air resistors 47 and 48 are adjusted so that relay 42 is just energized. To detect the interface between air and an organic (electrically non-conductive) solvent contact 64 is selected. The probe is driven downwards until the interface is reached, whereupon relay 42 is de-energized to open contacts 42a, stopping the motor, and to close contacts 42b, lighting lamp 68. Meter 56 indicates the position of the interface. Resistors 51, 52 are adjusted, while the probe is in the organic solvent, so that relay 43 is de-energized. To detect the interface between the organic solvent and an inorganic (electrically conductive) solvent contact 65 is selected and the probe is driven downwards until the interface is reached, relay 43 is energized, contacts 43a are opened, stopping the motor, and contacts are closed, lighting lamp 69. Meter 56 then indicates the position of the second interface.

Abstract: 874,648. Rotary screens. DAVEY, PAXMAN & CO. Ltd. March 28, 1960 [April 10, 1959], No. 12263/59. Class 46. A rotary filter particularly for concentrating primary raw settled sewage sludge comprises a cylindrical screen 3 internally fed with sludge through a pipe 2 from a distributer 1, the screen 3 being rotatable about a horizontal axis and having apertured annular plates at either end. The plate 7 covering a fixed aperture of maximum diameter at one end of the cylindrical screen 3 has an opening 4 of greater diameter than that at the other end and is formed with a cutting edge around the opening 4 and means for varying the diameter of the said opening. This may be achieved by the substitution of plates 7, one for another, with cutting apertures of different diameters or, by the use of sharp-edged interleaved segmental plates 8 formed into an iris-shaped diaphragm, the segmental plates 8 of which are mounted on pins 11, themselves mounted on a backing plate 9, attached to the end of the screen 3. The plates 8 have pins 12 engaging in slots 13 formed in an actuator ring 10 having an extension 14 rotated by means which may be automatic and which also may be made dependent upon the moisture content of the sludge, the rotation causing the plates 8 to pivot thereby varying the size of the opening 4. The end of the plug of sludge formed inside the cylindrical screen 3 is periodically cut off by the sharp-edged aperture 4 and is removed for further treatment in a rotary concentrating filter 5 of known design and to which is fed, by a conveyer 6, the output of other filter screen.
