Title: Improvements in and relating to the manufacture of bolting cloth, grit gauze and the like
IPC: D06M15/17
Filed: 1942-05-19
Abstract: 557,487. Treating textiles with liquids &c. ; resinous condensation products. COURTAULDS, Ltd., and McFARLANE, R. A. May 19, 1942, No. 6774. [Classes 2 (iii) and 15 (ii)] Bolting cloth, grit gauze, and the like is made by weaving in a plain or leno weave nylon threads containing one or more continuous filaments, and causing the warp and weft threads to adhere at their crossings and thus prevent them from slipping over one another by treating them with a resin-like polyhydric-polybasic acid condensation product in presence of 0.1-20 per cent. calculated on the weight of the resin of diphenylguanidine, phenol, trichlorethylene, or other organic compound which is a wetting agent for the nylon and which assists the nylon to take up the resin-like condensation product. The alkyd resin may be mixed with other synthetic resins or it may be modified by heating with oil, or urea, or urea-formaldehyde condensation products. The fabric may consist wholly of nylon threads, or it may be made from nylon and other threads such as silk or rayon. The fabric is stiffened and its wear-resistance is increased by the treatment.. In an example, phthalic anhydride and castor oil are heated together at 220‹ C. Glycerin is added and the mixture is heated in a current of nitrogen at 220-240‹ C. till the resin has a glycerin-like consistency at 180‹ C. The resin is cooled to 150‹ C. and diluted with ethylene glycol ethyl ether. The resin is mixed with a small amount of diphenylguanidine, and with benzol, and ethyl alcohol. A nylon bolting cloth woven in leno weave with monofil is passed through the mixture, and the cloth is dried on a pin stenter. Specification 461,237 is referred to.

Abstract: 589,839. Pipe joints. HUMPHREYS, G. H. March 19, 1945, No. 6820. [Class 99 (i)] A tubular fitting 1 for use with a flexible pipe 7 has at least two annular outward bulges 3, 4 which are forced into said pipe and the fitting then secured by the tightening of the band clips 8 and 9. The fitting may be used for joining two pipes by forcing the second pipe over the bulges 4, 5, and 6. The spaces 2a, 3a, 4a, 5a between the bulges are concave and the internal bores of the band clips are of similar section.
Patent GB-352448-A (GB)
Title: Improvements in or relating to the conversion of liquid carbonaceous materials into products of low boiling point
Filed: 1930-03-01
Abstract: <PICT:0352448/III/1> <PICT:0352448/III/2> <PICT:0352448/III/3> Synthetic hydrocarbons are obtained by vapourizing oils and leading the vapours mixed with steam under high velocity and in the absence of pressure through a spiral coil heated to about 1400 DEG  F. and provided at one end with a metallic catalyst.  The vapours produced may be further heated at higher temperatures to obtain fixed gases suitable for illuminating purposes.  Oil and water contained in storage tanks 1, 2 are pumped to a tank 29 for water and tanks 19, 21 for oil from which they are fed by air pressure supplied by an air main 40, to a spiral conversion coil 4 and to a burner 3x for heating the coil.  The water is preheated in a coil 26 and then serves to preheat the oil by passing through a coil 25 in a heat exchanger 24 to which the oil is fed through a pipe 19x the streams of oil and water being commingled in jets issuing from pipes 27, 19x, Fig. 2, at the entrance of the conversion coil.  The latter is situated in the central area 53 of a spiral-shaped conversion chamber 52, Fig. 4, and is provided at its lower end with an extended coil of catalytic material, e.g. a coil of nichrome wire 2-in. diameter and 24-in. long.  The products pass to a knock-out box 5 and thence through a condenser 6 cooled by a spray of water from the line 34 to a separator 7 from which the condensate is pumped to a still 8.  The vapours are fractionated in a column 9 and condensed in a condenser 10 leading to a receiver 11.  Gases separated in the box 7 are stored in a holder 12.  When it is desired to convert the vapour into a fixed gas the products are led from the box 5 through a pipe 55 to a fixation coil 54 from which the gases pass through a pipe 57 to the cooler 6.  Oil mixed with 10-50 per cent of water is passed at a velocity of several hundred feet per second through a 100-ft. coil 2\ba1/4\be-in. in diameter heated to 280-1500 DEG  F. and a product 60 per cent of which distils below 440 DEG  F. and contains no sulphur or free carbon is obtained.  Reference has been directed by the Comptroller to Specifications 119,485 and 160,907, [both in Class 32, Distilling &c.].

Title: Improvements in or relating to echo-sounding apparatus
IPC: G01S15/96
Filed: 1959-02-27
Abstract: 900,001. Echo sounding. ELECTROACUSTIC G.m.b.H. Feb. 27, 1959 [Feb. 27, 1958], No. 6954/59. Class 40 (7). In an echo sounding apparatus for detecting and recording underwater objects, e.g. fish shoals, a valve is placed between the receiver and the recorder and, while all echoes having less than a predetermined amplitude are recorded, echoes having a greater amplitude are not all recorded so that fish echoes cause the record to be dark relative to the sea bed echo contour, Fig. 2b. Received echoes 5, Fig. 3, are fed to thyratron 14 and to the grid of valve 7, which actuates the recorder 9, 10. Echo amplitudes in excess of U2 trigger the thyratron causing a negative pulse of sufficient value to cut the valve off to be passed to the grid of valve 7 so that echoes of amplitude greater than U2 are not normally recorded. However, periodically thyratron conduction is prevented by a negative potential which is applied to the second grid when the cam-operated switch 12 is open and in this case all echoes are recorded, with the result that a rastered recording of the higher amplitude echoes is produced.

Abstract: Pourable liquid mass is stored in a store (11). The store (11) has a mouthpiece (12) and a longitudinally displaceable piston (50). There is, furthermore, a rotatable member (46) which is aligned with the mouthpiece (12). The piston (50) is arranged on a threaded rod (38). The rotatable member (46) is connected to the threaded rod (38) by means of a worm drive. During use, the rotatable member (46) is laid on to the surface of the textile article, and the apparatus is displaced along the permanent pressed crease to be formed. The rotatable member (46) thus rotates and displaces the piston (50), so that the pourable mass is expressed. The store (11) is disposable. The apparatus allows a uniform dispensing of the quantity of pourable mass per unit length of the pressed crease and is simple and cheap to produce. <IMAGE>
