Title: Shaping of fabrics
IPC: D06C23/04
Filed: 1974-04-26
Abstract: 1510631 Finishing fabrics WIRA 14 July 1975 [26 April 1974 14 Sept 1974] 18265/74 and 40150/74 Heading D1S Fabrics containing or comprising yarns of fibres and/or filaments which are shrinkable by a treatment process are shaped by applying the treatment process to the fabric and restraining the shrinkage of the fabric in some part or parts of the fabric as compared to the shrinkage of the remaining part(s). In one aspect, the fabric is knitted or woven and comprises or contains yarns which, upon treating under zero tension, shrink in length by at least 15%, and which upon treating, while held at constant length, exert a tension of at least 0.1 g/tex. Preferably, the shrinkable fibres and/or filaments are of high-shrinkage polyester or stretch-set acrylics and are such that the shrinkage does not develop below 100‹C so that conventional finishing, e.g. dyeing, can be undergone without shrinkage occurring prior to the shaping stage. Heating may be accomplished by steam, e.g. the fabric is steamed in an autoclave for 2 minutes in saturated steam at 120‹C and 1¢ atmospheres pressure. Alternatively, heating may be by a hot gas, e.g. hot air, or by radiant or dielectric heating, moisture being applied before or during heating. In a second aspect, the shrinkable fibres and/or filaments are polymeric and shrinkable when treated with a suitable swelling solvent having a cohesive energy density similar to that of the fibres and/or filaments. Methylene chloride is a suitable swelling solvent for polyester fibres. Preferably, the fabric is stabilized in the three-dimensional shaped form by maintaining it in the desired shape and continuing to subject it to the treatment process until the residual shrinkage potential has been dissipated. A setting and/or a stabilizing agent may be applied to the fabric before, during or after the treatment process. The shrinkage of the part(s) of the fabric may be restrained by clamping means and a three-dimensionally contoured former or, if the fabric is produced in, or shaped into, the form of a tube or cone, the clamping means may be dispensed with and the fabric shrinkage at least partially restrained by the fabric being shrunk onto a contoured former. The yarns of the fabric may incorporate non-shrinkable fibres and/or filaments. The fabric may be attached face-to-face with a second fabric so that, as the shrinkable fabric is shaped, the second fabric is also shaped to a certain extent.

IPC: F41J5/12
Filed: 1960-05-25
Abstract: 941,320. Aerials; radio navigation. M. L. AVIATION CO. Ltd. May 25, 1961 [May 25. 1960], No. 18494/60. Headings H4A and H4D. [Also in Division F3] An aircraft target practice system comprisse an aerial in the target 1 radiating radio signals in a flat beam 4 encircling the target in a vertical plane and a missile 6 fitted with a receiver responsive to the signals to operate a visual indicator device. An ultra-high frequency signal transmitted from the target is picked up by the receiver circuit shown in Fig. 2, which sums the pulses received and operates the indicator on receipt of a predetermined number of pulses. The missile has a two-part casing 31, 32 of conductive material separated by insulating, material 33 to form an aerial, the signals picked up being demodulated by a component 34. The rest of the receiver circuit is cast in a body of resin 35 and is in open circuit with a battery 36 until after the missile is discharged, while the firing circuit is connected to a fuze 37 for igniting flash powder 67. On discharge of the missile, the propellent gases flex a diaphragm 40 and so cause initiation of a delay train 42. The delay ignites a powder charge 43, the gases from which impinge on a diaphragm 44 and so press a plunger 45 against a lever 46. A shear pin 48 breaks and the lever 46 bridges contacts 50 by means of a conducting part 49 to complete the circuit from the battery 36 to the radio receiver. At the same time, lever 46 frees an inertia rod 54, which then moves to uncover a port 65 leading from the fuze 37 to a relay 66 for the flash powder 67, which provides the visual signal. A cover 68 of synthetic resin encloses the powder 67 and a leaf spring 63 locks the rod 54 in the retracted position, so that the powder is fired as soon as the received signals have built up a voltage sufficient to energize the firing circuit. The receiver circuit is illustrated schematically in Fig. 2 (not shown).

IPC: B21D5/01
Filed: 1928-06-29
Abstract: 313,328. Hayward, T. A. June 29, 1928. Tubes. - Straight plates are bent round a mandrel to form tubes by transversely moving bending members on a rising and falling table. The table d is guided on columns e and actuated by hydraulic rams c. The transversely moving bending members k comprise cylinders m moving on hydraulic rams l. The upward bending pressure on the mandrel j is taken by a cross-head i on hydraulic rams h. During the first half of the bending the blocks k move outwards as the table rises, the ends of the blocks being curved for this purpose; after passing the widest part of the mandrel the blocks move inwards under their hydraulic pressure and complete the bending, as shown in Fig. 5. At this stage the pressure of the cross-head is relieved by contact of the bending blocks with the projections i<2> and the downward pressure on the mandrel is taken by rams r<1> adjusted by screw sleeves r actuated by worm gearing r<2>. Friction on the bending blocks may be reduced by draping them with mats of anti-friction rollers n, Fig. 7, supported by chains p and weights o.

Title: Improvements in flame detector or flame failure protection systems
Inventor: PEARSON EDGAR
IPC: F23N5/12
Filed: 1956-06-20
Abstract: 819,099. Controlling burners. COLNE SWITCHGEAR (K. & W.) Ltd. June 19, 1957 [June 20, 1956], No. 19027/56. Classes 75(1) and 75(3) A flame detector comprises a pair of electrodes E, E<SP>1</SP> arranged in the flame and connected to the secondary winding of a transformer A, the primary winding of which controls a relay F adapted to control a device for indicating the presence or absence of the flame. On closing the switch I and the press button switch J the primary of the transformer is energized and a solenoid gas valve G is opened to supply gas to a burner K which is ignited by known means. A spark discharge takes place between the electrodes in the flame and the primary current of the transformer operates the relay F to close contacts FC shunting the press button switch J which can now be released. In the event of flame failure sparking between the electrodes ceases and in consequence the primary current of the transformer falls causing the contacts FC of the relay to open. A resistance D in the secondary circuit of the transformer minimises the generation of electro-magnetic waves. In a simplified circuit, Fig. 1, not shown, the rectifier C in the primary circuit is dispensed with and the relay contacts may be used to operate a signalling system instead of a fuel valve. In a modified circuit, Fig. 4, not shown, the transformer has a tapped primary and at starting the supply voltage is connected by a push button switch to a portion only of the primary winding and in consequence the secondary voltage causes sparking between the electrodes E, E' in the absence of a flame, the sparking being used to ignite the burner. The closing of the relay contacts, as a result of the sparking, energizes a gas valve and also connects the whole of the primary winding to the supply through a choke so that, when the push button starting switch is released, the secondary voltage is reduced to a value sufficient to maintain sparking only in the presence of a flame. In an alternative arrangement, Fig. 5, not shown, an auto-transformer is connected in series with the primary of the transformer to boost the primary voltage at starting when the electrodes are used for ignition.
