Abstract: 1,189,927. Apparatus for treating textiles. BRUCKNER-TROCKENTECHNIK K.G. 11 Sept., 1968 [27 Sept., 1967], No. 43168/68. Heading D1L. A device for treating a continually moving fabric web in at least three successive treatment zones (e.g. washing, drying, dyeing), wherein the web is held at its edges during passage through the first and third zones, but released during passage through the second zone, comprises a common feed and clamping device 6 which holds the web 4 in the first treatment zone 1, means 8 for disconnecting the web from device 6 for passage through the second zone 2 and means 10, 11 for reengaging the device 6 onto the web 4 at the start of the third zone 3. The disconnecting device 8 may be a needle release rod and the reclamping means a roller 10 and spiked brush roller 11 having an adjustable speed of rotation. The clamping device 6 moves in guides 7 which have moveable joints 12-14. Thus the clamping device can follow a path which takes account of the shrinkage which occurs during the web's free travel through zone 2. The positioning of the guides may be automatically controlled by a device which detects the web edges at the end of zone 2. The zone 2 may comprise a pair of squeeze rolls 5; or a rotary suction drum 15 (Fig. 3 not shown), the segment over which suction is applied being either the whole of that over which the web is in contact with the drum or a segment over the upper part of the path only; or it may comprise a fixed body having an orifice in its upper surface through which suction is applied. The brush 11 may re-apply the web 4 onto clamping device 6 in folds to account for .any longitudinal stretching which may have occurred in zone 2.

Abstract: 440,322. Cables. HENLEY'S TELEGRAPH WORKS CO., Ltd., W. T., 11, Holborn Viaduct, London, and DUNSHEATH, P., Hesket, Church Avenue, Sidcup, Kent. June 20, 1934, No. 26490/35. Divided out of 439,836. [Class 36] In a method of manufacturing a cable of the kind described in Specification 400,929, i.e. a cable having compressed gas cushions of relatively short longitudinal extent located in contact with an impregnated paper dielectric 2 between this and a sheath 11 which is spaced from the dielectric by a helically wound strip 16, a portion of the space between the dielectric and the sheath is filled, prior to sheathing, with a viscous compound so located as to allow longitudinal flow of gas and, after sheathing, followed by the forcing in of compressed gas in a longitudinal direction to the remainder of said space, the compound is caused to run down to and collect in the lower part of the space between adjacent turns of the helical strip and thereby divide said space into short lengths. In the construction shown, the space formed by the helical strip 16 is divided into two coaxial compartments 5, 10 by a barrier layer 6 consisting of a helically wound perforated metallized paper tape, one of which compartments is filled during the early stages of the manufacture of the cable, before sheathing, with the viscous compound. After the application of the sheath 11 and the charging of the cable with compressed gas, the compound is caused to run down into the lower parts of the compartments 5, 10, as shown in Fig. 5, by heating the cable internally or externally to such an extent that the compound is rendered sufficiently fluid to run through the perforations 7 in the barrier layer 6. The helical strip 16, which is of metallized paper, is applied in two superposed layers 3, 4 between which is disposed the edges of the perforated strip forming the barrier layer 6. Over the layer 4 is wound a metal tape 8 having adhering to its outer surface a strip of solder 9 which unites with the sheath 11 when the latter is applied. The sheath 11 is protected against pressure and mechanical injury by two layers of brass tape 12 applied over a bedding 13 of paper. An outer lead sheath 15 completes the cable. In modified constructions the cable is formed without the barrier layer 6, the compound being applied to the surface of the dielectric in the form of dry powder, or of strips formed of or impregnated with viscous compound, and being subsequently rendered fluid by heat.

The sealing and severing jaws 46 are carried on blocks 45 moved in orbital paths in a vertical plane by cranks 52. The cranks 52 are mounted on shafts 28, 57 connected by gearing 54-56, the shaft 28 being driven through a clutch 29 from a constantly driven shaft 30. The web may bear printed markings to determine package lengths. The markings are scanned by photoelectric means 59, the latter controlling operation of the clutch 29 and thus the periods at which the jaws 46 engage the tube and move with it during sealing and severing.

Abstract: 1,013,152. Pressure measuring devices. R. T. YOUNGMAN. Feb. 14,1962 [Dec. 23, 1960], No. 44228/60. Heading G1L. Apparatus for determining the ratio of two pressures e.g. the input and output pressures of a jet engine comprises pressure sensitive members 1, 2 having push rods 4, 5 pivotally connected at 6 to a resolving link 7 pivoted at 9 on a rotatable crank 10. A vacuum capsule 12 with a push rod 13 connected to point 6 is provided to compensate for the pressure on the outside of members 1, 2 so that the pressure ratio determined may be the ratio of the absolute pressures. Alternatively the capsule 12 may be omitted and casing 3 evacuated. When resolving link 7 is moved, by the forces developed in members 1, 2, to a position where its axis is not parallel to that of crank 10 a contact 8 is either made or broken to operate a signal. The ratio between the pressures at which this signal is given depends on the angular position of crank 10. The crank 10 may be set at a predetermined value so that the signal is given at a predetermined angle or alternatively the signal can operate a servo system which adjusts the position of the crank 10 until the axes of the crank and link 7 are parallel. An indicator is connected to crank 7 to give a continuous indication of the ratio of the pressures. Specification 832,766 is referred to.
