Title: Fabric-like material composed of adhesively-bonded fibres
IPC: D04H1/66
Filed: 1953-03-27
Abstract: 764,086. Agglutinated fibrous sheet materials. CHICOPEE MANUFACTURING CORPORATION. March 27, 1953 [April 7, 1952], No. 8517/53. Class 140. A fabric composed of adhesively-united fibres is made by rebonding in its stretched state an oriented web of textile fibres that has been bonded by adhesive applied in a regular pattern and has then been stretched at right angles to the direction of orientation of the fibres in such a way as to displace the fibres angularly relatively to the adhesive pattern. The patternbonded web may be impregnated with an aqueous dispersion of a binder, stretched while wet, and dried while stretched. Alternatively, the pattern-bonded web may be wet with water, stretched while wet, and then re-bonded while stretched, or, in the case of a web that has been bonded by spaced small areas of adhesive, e.g. annuli 24, the web is stretched crosswise while dry to produce sinuous bands of fibres 20 and 22, and the stretched web is re-bonded by impregnating it or by printing with a second adhesive pattern which may consist of continuous or broken lines, e.g. 26 and 28. The lines of the second adhesive may be arranged diagonally, may form a zig-zag pattern, or a series of elongated diamonds or parallelograms. The procedures and adhesives described in Specifications 468,529 and 642,890 may be made use of. One or both printing operations may be effected by hot-printing with a thermoplastic adhesive as described in U.S.A. Specification 2,545,952. A web may be patternbonded with a polyvinyl acetate adhesive, and, after stretching, impregnated with a polyvinyl chloride emulsion. The adhesive used in the first pattern-bonding operation may be watersoluble, e.g. starch, polyvinyl alcohol, or carboxymethyl cellulose, and may be dissolved out after the second pattern-bonding operation which is effected with a water-insoluble adhesive such as rubber latex, polyvinyl acetate or chloride. The product may be united with an untreated or pattern-bonded fibrous web, e.g. by passing through hot rolls which melt the adhesive. The treatment of carded webs of viscose rayon staple fibres is referred to. Specification 744,839 also is referred to. Reference has been directed by the Comptroller to Specifications 688,985 and 693,711.

Title: Improvements in or relating to uv flame monitor
IPC: F23N5/08
Filed: 1970-02-23
Abstract: 1283472 Controlling burners PAG PATENT GES AG 23 Feb 1970 [28 Feb 1969] 8582/70 Heading F4T [Also in Division G1] In a U.V. flame monitor for a burner in continuous or intermittent use, two U.V. tubes, 1 and 2, are arranged so that they are alternately periodically masked from the flame, suitably by use of a rotating perforated disc 3 (Fig. 1); as shown in Fig. 2, or direct current supply 5 is fed through a resistance 6 to the two U.V. tubes 1, 2 which are connected, together with associated delayed lapse relays 9, 10, in parallel circuit branches, the rest of the circuit providing means for interrupting the flow of current through the tubes, when at least one of the tubes is not irradiated by the flame. The contacts of the two relays 9, 10 are connected in series through lines 50 and 51 with a switching device, e.g. a magnetic valve 54 which controls the supply of fuel to the burner. When one of the tubes, e.g. 1, is irradiated and thus energized by the flame, a current I 9  flows from the positive terminal of the direct current supply through the resistance 6, relay 9, tube 1, and back to the negative terminal of the direct current supply, causing the contact of the relay 9 to close. The perforated disc 3 rotates to mask the tube 1 and in the intermediate time before tube 2 is unmasked, a condenser 12 charges to the breakthrough voltage of a four-layer diode 13, which then breaks down and discharges the condenser through a pulse transformer 14. A current pulse is thus applied to the control electrode 46 of a thyristor 15, which fires, discharging a second condenser 17 into the circuit of tube 1. A negative voltage is produced at the anode of tube 1, so that the tube is extinguished and subsequently the voltage on it rises to the supply voltage 5. The contact of the relay 9 remains closed, due to its delayed lapse. As soon as the tube 2 is unmasked the relay 10 is actuated in a similar process to that described for relay 9, and consequently the lines 50 and 51 are connected and fuel is allowed to flow to the burner. It follows that the delay lapse of the relays must be longer than the rotation time of the disc 3. In the event of there being no flame, or failure of one of the tubes, the lines 50 and 51 are currentless and the fuel supply to the burned is cut off. Modifications of the circuit shown in Fig. 2 are also described (Figs. 4 and 5, not shown).
