Title: Improvements in and relating to the finishing of woven fabrics
IPC: D06C29/00
Filed: 1946-08-29
Abstract: 632,655. Finishing fabrics. BLEACHER'S ASSOCIATION, Ltd., and MELVILLE, A. Aug. 29, 1946, No. 25905. [Class 42 (i)] Woven textile material is treated by supporting it on a hard base and applying substantial pressure to it by means of a comb-like formation having resilient smooth-tipped. blades, relative to which the fabric is moved. The fabric may be carried on the hard rubber surface 11a of a roller, mounted in frames 12 and 13, and driven by an electric motor 14. Rotatably mounted in the frames 12 and 13 are a number of shafts 15, to one end of each of which is clamped an arcuate rack 16, engaging a gear-wheel 17 which is capable of slight rotation by handles 20b, so that the inclination of the shafts 15 may be altered simultaneously. The shafts 15 are each provided with a longitudinal slot, in which a blade-holder carrying a large number of blades 22 may be secured by members 24. The blades 22, which may be made of stainless steel or of a phenol-formaldehyde synthetic resin, may be spaced at about 5 to 1000 per linear inch, and may be resiliently mounted, e.g. in a rubber block, and are brought to bear upon the surface of the fabric, when they enter the interstices between the threads. Provision may be made for giving the blades a limited vibratory movement, or for heating them. The pressure applied by succeeding rows of blades may increase or decrease. The fabric, which may be treated either longitudinally. or transversely, or both, may be heated or moistened, and during or before treatment it may have a plastic or film-forming material such as a synthetic resin or a cellulose ester applied to it, or it may be rendered stiff by a chemical treatment. The blades or combs may be mounted on a rotating shaft, forming a roller with the multiplicity of tips forming a discontinuous surface, and the fabric may be supported on a bed other than a cylinder, which may be stationary or in the form of a moving band or conveyor, and may be flat, convex or concave.

Abstract: 1,212,629. Spline couplings. FORD MOTOR CO. Ltd. 21 May, 1969 [20 June, 1968], No. 25923/69. Heading F2U. In order to prevent relative axial movement under torque loading of spline-connected members, one of the members is formed with a small number only of teeth of full thickness, the remaining teeth being of reduced thickness. As shown for a gear-change pinion 60 on a drive shaft 50, all the internal pinion teeth are of equal thickness, but only a small group 90, 92 ... 98 of the external shaft teeth are shaped to engage without clearance, the remaining teeth having clearance on one or both flanks. In the former case all the teeth are effective during forward drive, but only the small group during reverse when gear " jump-out " is more liable to occur. The apices of the shaft teeth engage the roots of the pinion teeth for piloting action during axial movement of the members.

Title: Improvements in or relating to safety control devices for gas burners
Inventor: EVES ERNEST WILLIAM
IPC: F23N5/10
Filed: 1958-08-21
Abstract: 864,817. Controlling burners. PERL CONTROLS Ltd. Nov. 23, 1959 [Aug. 21, 1958], No. 26923/58. Class 75(1). An electric device for shutting down a burner in the event of flash back in the burner supply pipe 10 comprises a thermal switch or a device dependent on flame conductivity or a thermocouple 9 actuated by the flash back and adapted to energise a winding 8 on a magnet or electromagnet 2 to demagnetise the magnet or electromagnet whereby the armature 3 is released and closes a valve supplying combustible mixture to the burner. The apparatus also shuts down the burner in the event of flame failure of the burner itself or of a pilot burner 7 since the electromagnet 2 is magnetised by a second winding 5 energised by a second thermocouple 6 heated by the burner or the pilot burner 7. The electromagnet 2 may however be magnetised by the winding 5 being energised by a current controlled by a thermal switch or a flame conductivity device actuated by the burner or pilot burner 7. The thermocouple 9 is mounted downstream of a flame trap 11 in the supply pipe 10. In the arrangement shown in Fig. 2 a rectifier 19 disposed in the flame of the, burner or pilot burner passes current through a resistance 18 to bias the valve V2 beyond cut-off. When the flame fails the valve V2 conducts and a resistance 14 in its anode circuit provides a bias voltage which cuts off the anode current of a second valve V1 so that the magnetising winding 5 of the electromagnet is de-energised, causing shut down of the burner. Shut down in the event of flash back is effected by a similar circuit comprising valves V3, V4, a conductive gap 23 mounted in the burner. supply pipe and a demagnetising winding 8 on the electromagnet. If flash back occurs the gap 23 conducts and a voltage builds up on resistance 21 to cut off valve V4. The cut-off bias on resistance 20 is thus removed and valve V3 conducts to energise winding 8 so that the electromagnet is demagnetised, causing shut down.
