Title: Improvements in the treatment of natural and artificial filaments, threads, ribbons,fabrics and like materials
IPC: D06M11/48
Filed: 1934-08-30
Abstract: Artificial textile materials are treated with a gaseous acid so as to form therein a waterinsoluble inorganic compound by reaction with a reagent already contained in the materials.  The use of gaseous acid anhydrides is excluded.  The materials may be artificial filaments, threads, ribbons, or fabrics, and may be of cellulose or other cellulose ether, or regenerated cellulose. Mixed materials comprising artificial and natural threads or different kinds of artificial threads may be treated.  The first reagent may be incorporated in artificial textile materials after their formation or in the spinning solutions.  It may be incorporated in the materials from solution in water or alkali. The insoluble compound formed may be a compound of the gaseous acid or it may be silica, alumina, oxides of tin, lead, or tungsten precipitated from alkaline solution by gaseous acid.  The gaseous acid may be hydrochloric acid, or acetic acid.  In the treatment of cellulose ester materials, the first reagent may effect partial hydrolysis of the cellulose ester.  Sodium silicate, methylamine silicate, ethylene diamine silicate, or tetramethyl ammonium silicate may be used.  Swelling agents may be present. Yarns may be treated in hanks or while travelling with or without tension in warp formation.  The materials may be treated with wetting agents such as soaps, sulphonic acids, or amino-alkylamides, or swelling agents prior to or during treatment with the weighting agents.  The materials may be subjected to shrinking or stretching treatments.  The degree of weighting is varied as desired.  It may just counter-balance the loss due to saponification or result in a large increase in weight.  It may raise the safe ironing point and increase the resistance to fire. The treatment may reduce the lustre of the textile materials or mordant them.  In an example, cellulose acetate hanks are immersed in sodium silicate solution, squeezed, hung in a closed vessel containing hydrochloric acid vapour, washed, and dried.  Cellulose acetate yarns in warp formation are passed through aqueous acetone, then through sodium aluminate solution, and through a chamber containing moist hydrochloric acid vapour. Specifications 323,790, [Class 2 (ii)] 340,324, 340,325, 340,326, 340,436, 340,437, 343,062, 378,858, 389,823, 435,806, 438,584, 438,585, 438,586, 438,587, 443,707, and 443,710 are referred to.  The Provisional Specification describes also the use of carbon dioxide, and sulphur dioxide, as the gaseous acidic reagent and the application of the treatment to silk and other natural textile materials.  The insoluble compound formed may be calcium or barium carbonate.  The first reagent may be an insoluble silicate of calcium, barium, or magnesium.

Title: Method and apparatus for removing liquid from plastic material in a mixing device
IPC: B29B7/84
Filed: 1958-08-05
Abstract: 852,173. Mixing rubber or the like. FARREL-BIRMINGHAM CO. Inc. Aug. 5, 1958 [March 20, 1958]. No. 25024/58. Class 86 [Also in Group XIII] Liquid, e.g. water, is removed from a plastic material, such as rubber, being treated in a mixing chamber by subjecting the material to pressure by means of a ram so arranged in a guideway that the separated liquid may escape from the mixing chamber without escape of the material. As shown, the mixing chamber 10 has conventional rotors and a discharge door 12. The charge is introduced over a slideway 18, the ram 13 being raised to the dotted line position. The ram is rectangular in plan and is guided by a shoot 14, the clearances between the ram and the shoot being sufficient to permit liquid to pass to above the ram, but too small to allow the rubber or the like to do likewise. The ram is raised and lowered by a double acting cylinder and piston 22, 23 and the liquid which is squeezed out of the rubber collects in troughs 27 from which it is removed by a suction pump and tubes 28, the latter being flexible so that springs 31 and curved guides 30 keep them correctly presented to the shoot 14 and ram rod 19. The slideway 18 is movable to a vertical position to close the side of the shoot 14. The removal of liquid from the mass may be accelerated by circulating a heating medium in the jacket 11. in which case the ram 13 is periodically raised to permit evolved gases to escape through a vent 35, or vacuum may be applied to the mixing chamber.

Abstract: 167,401. Lloyd, A. H. Sept. 4, 1920. Reamers.-An adjustable reamer is constructed so that the blades float. The blades B are adjustable in slots in the head A<2>, are held therein by a cover-plate A<5>, and are pressed inwards by springs B<3> abutting on the bottoms of notches B<4>. The body is bored to receive a mandrel, the main part C of which is guided in the bore. The head C<2> of the mandrel is spheroidal or barrel-shaped so that it has point-contact only with the bevelled ends of the blades, and is grooved or flattened at C<4> to allow the blades to be moved inwards during the withdrawal of the tool. To allow the blades to float, the operative end of the mandrel is jointed at C<2> to the main length. When there are only two blades, as shown, the joint C<2> is a pin joint, but when there are more than two blades a universal joint is necessary. A rotatable collar D is connected to the mandrel by a pin D<2> passing through a slot in the body. By rotating this collar the blades are projected and withdrawn and by moving the collar endwise by means of nuts D<4> the diameter of the hole is varied. Automatic means may be employed to collapse the reamer on the comple. tion of the work, e.g. the collar D may be spring- loaded and secured by a catch which is recessed automatically when the work is completed. Means other than the collar D may be used to manipulate the mandrel.

Abstract: 1324555 Electric storage heaters LANDIS & GYR AG 19 April 1971 [7 April 1970] 25877/71 Heading F4U  The charging and discharging of an electric storage heater are both controlled by a single thermostat. In the form of Fig. 1 the heat accumulator is heated by heater 4 in series with a safety switch 5, opening at an upper limit, and a control switch 6. Switch 6 is opened and closed by a thermal device 7 in series with contact 10 and remote timer-controlled switch 16. The discharge fan 8 is in series with contact 11 and switch 14, the operator 15 of which is set by the customer to put the heater into the charging or discharging condition. Contacts 10, 11 are controlled by a temperature sensor 9 which is subject to the ambient air and two compensating heaters. In the charging position shown resistor 13 is energized. In the discharging position resistor 12 is energized. These resistors have the effect of causing thermostat 9 to respond at a roomtemperature lower than that desired. When contacts 10 and 11 are closed the fan 8 is energized to discharge the heater and thermal device 7 is energized, after a preset time to close switch 6 and cause recharging. If switch 16 is also closed the thermal device in effect sums the periods of discharge and causes recharging if a given value is reached. The thermostat may be mounted on the storage heater, being thermally coupled to it as described in Specification 1,324,707. In the form of Fig. 2 (not shown) the thermostat is a bulb containing a liquid and a bellows for sensing the vapour pressure in the bulb. The bellows operates a wiper on a resistor in series with the fan and operates also a switch (as 6) in the circuit of heater 4. The bulb has an auxiliary heater 13 and may also have a thermal coupling with the storage heater.
