Abstract: 1371555 Web decatizing apparatus A MONFORTS 15 Aug 1972 [28 Sept 1971] 38087/72 Heading D1L In a method for decatizing a continuous web of textile material the web is passed around a perforated decatizing cylinder 5 between the cylinder and an endless air-impermeable belt 6, the steam required for the decatizing process being generated by moistening either the fabric-facing side of the belt 6 by means of spray 9 from spray assembly 8 or the web itself (dotted lines 1a), heating the decatizing cylinder to the required temperature and pressing the belt and web against the cylinder at the required pressure by means of suction applied to the perforations of the cylinder from the inside thereof. The decatizing cylinder comprises a casing 20 formed with end walls 22 and 23 and rows of perforations 28 surrounded internally by welded semi-circular tubes 21 (see also Fig. 2, not shown). The spaces surrounded by the tubes 21 are evacuated by a pump (not shown) via a stationary control head 25 and flange 26 to suck the web 29 and surrounding belt tightly against the surface of the cylinder. Steam under pressure (e.g. 3 atmospheres) is fed to the inside of the pressure vessel formed by the casing 20 and end walls 22, 23 via rotary inlet 24 and heats the surface of the cylinder to the required temperature. The stationary control head 25 is pressed firmly against the side of the cylinder by springs 30 and is designed so that only those rows of perforations 28 in contact with the web 29 are subjected to reduced pressure.

Abstract: 903,393. Insulators. PETROLITE CORPORATION. Dec. 2, 1958 [Dec. 5, 1957], No. 38809/58. Class 36. [Also in Group II] An insulator for use in oil chambers, especially where the oil may be contaminated, comprises an elongated core of rigid insulating material with conducting end fittings, a tube of a second less-rigid insulating material placed around the core so that there is an annular space therebetween, means for attaching the core member to the wall of the oil chamber with the exterior of the tube and the end of the annular space exposed to variations in oil pressure, and a movable pressure transfer element separating the annular space from the oil to equalize pressures on the inner and outer surfaces of the tube. A suspension insulator for supporting an electrode in a high-voltage emulsion treater has a cylindrical core 30, e.g. of ceramic or a silicone-resin-bonded glass fibre laminate, formed with a centre portion 31 and end portions of reduced cross-section over which metal end fittings 32 and 33 are secured by pins 34, the end fittings terminating in threaded studs 35 and 36 for securing the insulator to the equipment casing and the electrode to the insulator respectively. A tube 40, preferably of polytetrafluoroethylene or polytrifluoroohloroethylene, fits over the core with a very small annular clearance and is located by end caps 52 and 53 having clearance openings through which the external oil can penetrate. The end fittings 32 and 33 are of reduced diameter near the ends of the outer tube thus forming enlarged annular openings 42 and 46 into which resilient rings 44 and 48 fit to seal the interior of the annular space, between the ends of the insulator, from the exterior oil space. The whole of the free space within the insulator between the sealing-rings is preferably packed with a virtually incompressible fluid such as a silicone grease to facilitate transmission of pressure variations which is accomplished by movement of the sealing rings. A similar construction for a bushing insulator in which a cable, fitted with corona shields where it enters the bushing, is led in through a hollow central core, is described (Fig. 4, not shown).

A nuclear reactor control rod comprises a tubular structure in which are housed a plurality of fuel elements and at least one tubular casing supporting a plurality of cobalt plates. The cobalt plates serve the dual function of neutron absorption and the production of radioelements. As shown in Fig. 1, the tubular structure 1 is of square cross-section and comprises lower and upper end connectors 2, 3 between which extend two side plates 4 and two distance plates 5 which are inset between the side plates 4. Plate-type fuel elements 6 are fitted in the structure 1 adjacent the lower end connector 2, and two casings 7a, 7b are mounted above the fuel elements. Each casing contains a plurality of small cobalt plates 8, each clad with stainless steel or other suitable corrosion-resistant material, and each casing comprises an inner and an outer element of square cross-section which are provided with coolant apertures and also means whereby they can be assembled temporarily so as to form between them an annular space capable of accommodating the cobalt plates 8. The casings 7a, 7b are maintained within the structure 1 by means of a clamping plug 9, one portion 9a of which is in the form of a spring. The plug 9 is attached by means of screws (not shown) to the upper end connector 3 which is, in turn, attached to the side plates 4 by means of two threaded rods 11 co-operating with tubular nuts (not shown). This arrangement facilitates the loading and unloading of the cobalt plates 8. Such control rods are particularly suitable for use with reactors of the swimming-pool type.
