Filed: 1972-11-09
Abstract: 1405490 Dyeing apparatus VALD HENRIKSEN AS 9 Nov 1972 [17 Nov 1971] 51772/72 Heading D1L In apparatus for the liquid treatment (e.g. dyeing) of textile materials arranged on replaceable inserts in a container through which the liquid is continuously circulated, improved heat transfer between heating means provided in the container and the treatment liquid is achieved by arranging the circulating means to circulate the liquid in two differently directed flows, one passing through the material and the other in close proximity to the heating means. In one embodiment [Fig. 1, and Fig. 6 (not shown)] the material 8, in wound form, is arranged on perforated pipes 9 and the circulating means 3 is in the form of a doublerimmed impellor pump, the inner rim 5 of which circulates the liquid via tube 6 and distributor 7 out of contact with the textile material (as shown by thicker arrows 12) to return to the pump over heating means 2 and the outer rim 4 of which is separated from rim 5 by ring 23 and circulates the liquid through the textile material (arrows 11) via the perforated pipes 9 and distributor chambers 10. In other embodiment the two flows are produced either 'by providing the container with two different circulating pumps (Figs. 3 and 4, not shown) or by a single circulating pump 13 (Fig. 2) mounted outside the container and provided with two inlets to the chamber, one of which 16 is in the form of a nozzle.

Abstract: 1,254,129. Foamed propylene polymer/ion exchange composites. MITSUBISHI PETROCHEMICAL CO. Ltd. 28 Oct., 1969 [31 Oct., 1968], No. 52667/69. Headings C3B, C3C and C3P. A microscopically foamed propylene polymer matrix which is molecularly oriented in three dimensions has an ion-exchange resin finely dispersed therein, the wt. ratio of polymer to ion-exchange resin being 2 : 8 to 8 : 2 and the resin having swellability of not less than 3. The foamed composite may be made by mixing the polymer and resin into a shaped body which is then subjected at above 60‹ C. to an acid treatment and an alkali treatment. The polymer may be isotactic polypropylene or a copolymer of propylene containing a minor amount by wt. of comonomers, or a mixture of polymers containing propylene polymer as the major component by wt. In the examples the ion-exchange resins used were (1) an anion-exchanger made by reacting epichlorohydrin with bisphenol-A and then mixing the product with a condensating product of ethylene oxide with pentaethylenehexamine and diaminodiphenyl methane, and heating to complete curing and to evaporate off water and other volatiles, and (2)'a cation-exchanger made by sulphonating a styrene/divinylbenzene copolymer which is then mixed with a methacrylic acid/divinylbenzene copolymer (formed partly in situ).

Title: Method and apparatus for testing the gas permeability of foils
IPC: G01N15/08
Filed: 1972-11-15
Abstract: 1345460 Measuring gas permeability G H LYSSY 15 Nov 1972 [18 April 1972] 52807/72 Heading G1N To measure the gas permeability of a foil a pressure differential is initially set up across the foil, then the rise of pressure on the low side due to passage of gas through the foil is measured using a Pirani heated wire gauge. In Fig. 1 a chamber 11 is defined by two parts 10, 12 clamped together, rubber seals 18, 19 ensuring a gas tight joint. The foil to be tested covers a porous sheet 17, and is shown at f. The gas to be used is admitted at pipes 14, and then chamber 13 is evacuated by pump P via valve 3. The pressure in chamber 13 slowly rises, and at a given value the output from Pirani gauge 21, 22 is recorded on recorder 5; the recording continues until a higher predetermined pressure is reached, then when the pressure reaches a yet higher value preset at control unit 4 the valve 3 is opened and chamber 13 is evacuated again so that the measurement is repeated. The pressure to which chamber 13 is evacuated is also preset at unit 4. The pressures at which recorder 5 switches on and off may be set by contact devices on its scale 51. The measurements are repeated until the length of time for which recorder 5 operates becomes constant, this being necessary because the gas permeability tends to rise after the initial measurements. To calculate the permeability in cm<SP>3</SP> per m<SP>2</SP> per 24 hours at N.T.P., the foil area and the volume of chamber 13, pipes 15, 16 and the pore volume of plate 17 must be correlated. Recorder 5 carries out this calculation and prints the result; alternatively the timing and calculation may be done manually. The recorder 5, and control unit 4 both use temperature compensated bridges to determine the Pirani gauge resistance and hence the pressure; unit 4 may be combined with the recorder, or replaced by manual operation.
