Title: Improvements in method of applying foam to fabrics
IPC: B32B27/00
Filed: 1964-10-09
Abstract: A method of applying foam to fabric by expanding a chemical foaming mixture against a fabric is characterized by wetting the fabric with a liquid e.g. water, aqueous solution of carboxymethyl cellulose, gasoline, oils, freezing the liquid in the fabric to solid e.g. ice, expanding the chemical foaming mixture in contact with the frozen wetted portion of the fabric, retaining the liquid as a solid within the fabric during reaction of the foaming mixture to control the degree of foam strike-through into the fabric, and fluidizing the solid by heating before the resultant foam loses its tackiness to permit adherence of the foam to the fabric.  The fabric may be a discontinuous fabric e.g. of cotton, having interstices therein or a tufted loop pile carpet having a wool pile woven on a jute control. The liquid may be frozen to a solid to bridge the interstices.  The solid may be fluidized by heating before complete gaseous expansion of the foam mixture has occurred and before the resultant foam loses its tackiness to allow some strike through of foam into the fabric and to permit adherence of the foam to the fabric.  The chemical foaming mixture may be expended on the fabric between carrier and cover sheets.  The foaming mixture may consist of a resin comprising polyether and a polyisocyanate.

Abstract: <PICT:1068177/C1/1> Carbon black is prepared by injecting a make hydrocarbon feed into a flame formed by burning a fuel gas with a slight excess of air or other free oxygen-containing gas in a tubular reactor having a Venturi configuration.  The make hydrocarbon is fed through pipe 20 and is directed down the centre of reactor 11 by air fed through inlet 24 and the annular passage between pipes 20 and 18. Fuel gas is fed through inlet 23 and the annular passage between pipes 18 and 17 and passes into space 13 through holes 22.  The main air supply inlet is at 14 and the air is preheated by passing between reactor 11 and housing 10.  The air may be directed by rectangular vanes, as illustrated in Fig. 2 (not shown), when a flame of the longitudinal type is desired, or by helical vanes, as in Fig. 4 (not shown), for a flame of the centrifugal type.  These two Figures also illustrate appropriate "combustion aid devices" for each flame type in the form of a frusto-conical extension of the reactor 11 at the burner end, with louvres through which the air passes to the combustion zone.  A heat shield is disposed between this extension and the end plate 16 of housing 10.  The Venturi configuration is formed by a thickening of the refractory lining 12 of the reactor 11 and carbon black of improved structure &c. is obtained when the maximum temperature and turbulence of the flame is at the throat of the Venturi.  The reactor is connected to a quench section 26 with water spray 29.

An earth resistance measuring instrument includes a battery powered electric motor 5 connected to a mechanical current converter 10 having its input connected to receive direct current from a battery 6 and its output connected to supply alternating current to an earth circuit X under test. The electric motor is operated from the same battery 6 and contains a switch 7 and a rheostat 8 in its energizing circuit. Altering the resistance 8 will alter the motor speed and hence the frequency of the output alternating current. A suitable circuit for carrying out the resistance measurement which may be incorporated in the instrument includes a transformer 20 which supplies the A.C. power to the test circuit, and a transformer 21 which supplies the input A.C. to a resistor 22. The output voltage developed across the unknown earth resistance X is compared with that developed across the resistor 22 and the difference supplied to a mechanical rectifier also connected to the motor shaft to produce a D.C. which is supplied to the galvanometer G. The resistance 22 is adjusted until a zero reading is obtained in the meter and its value is then related to the unknown value of X. The apparatus of the invention replaces conventional types containing a hand-driven direct current generator. Specifications 688, 995 and 963,374 are referred to.
