A method for the continuous transfer of substance between liquids and moving webs for the purpose of impregnating or removing substances from the web comprises impregnating the web at least twice, preferably three times, and squeezing the imregnated web at least twice, preferably three times, in the nips of a squeezing-roll arrangement, impregnation and squeezing being alternated, the impregnation being effected at least once, preferably twice, to the complete exclusion of air, directly at the outlet side of one of the nips, and the treating liquid being guided through the impregnation baths in the direction opposite to that in which the web travels. Apparatus for carrying out the method comprises the combination of three relatively large diameter squeeze-rolls 11, 12, 13 in triangular or rectangular formation and one or more relatively small diameter squeeze rolls 18 arranged between the rolls 11, 12, 13 and forming a nip with each. The impregnation baths 21, 22, 23 are formed between the rolls and additional surfaces 27, 28 where necessary. The treating liquid is guided from the bath 21 to the bath 22 and from there to the bath 21. The larger diameter rolls are preferably made of steel and the smaller diameter roll preferably has an elastic material jacket e.g. polyamide material. Two of the larger diameter rolls may be stationarily mounted and the third, and fourth applicable, is movably mounted in parallel or swingable guides and is mechanically, pneumatically or hydraulically loaded.

Abstract: 972,101. Reactors. REACTOR CENTRUM NEDERLAND. Oct. 26, 1962 [Nov. 30, 1961], No. 40651/62. Heading G6C. In a reactor core in which the fuel is in the form of thin rods extending side by side through supporting lattices formed of thin strip material, fuel rods passing through the lattice meshes are spaced therefrom and centralized therein by spacer members. A number of zirconium alloy canned fuel rods 5 (Fig. 1) are placed in an open ended sleeve 1 to form an assembly of fuel elements. Two lattices, one towards each end of the sleeve 1, hold the fuel rods in position. Each lattice is formed of a number of suitable corrugated strips joined together as at 7. Each lattice is held against radial and vertical displacement in the sleeve by lattice supports 3, which comprise an arcuate midportion 9 abutting the lattice extensions, and top and bottom arcuate portions 10 which extend beyond the lattice edges in the direction of the width of the lattice strip. Fig. 5 shows a modification, in which the radial supporting tags 11 are curved outwardly, and the vertical supporting tags are curved outwardly, and the vertical supporting tags 12 are U-shaped. A fuel element is supported radially within each lattice space by a number of inwardly projecting tags 13 sheaved and formed from the lattice strip material. These support or spacer members may be in the form of single tags bent at right angles to the strips, stretchsheared tags connected at both ends to the strip (Fig. 5), pairs of inwardly curled tags (Fig. 6, not shown), or pairs of inclined cross-over tags having inwardly projecting dimples on the ends (Fig. 7, not shown). The last two embodiments have the advantage that they have a spring-like gripping action on the fuel rods. The lattice shape may alternatively be square, rectangular, diamond or triangular in shape; in the last case, alternate straight and corrugated strips are used. The strips may be joined by rivetting, stapling, soldering or spot welding, and the strip material may be stainless steeL

Abstract: 1,086,199. Endless conveyers. HUYCK CORPORATION. Oct. 15, 1964 [Nov. 15, 1963], No. 42187/64. Heading B8A. [Also in Division B5] An endless belt for transporting a moist web of faced corrugated paper through the heating and/or cooling sections of a corrugator combiner machine is formed of material permitting the transmission of moisture therethrough from the web, the material comprising substantially incompressible polymeric sheet material. As shown in Fig. 2, two top belts 49, 50 and a bottom belt 62 serve to transport an assembled corrugated web 20 under hold-down rolls along a tube 45 and facilitate the removal of moisture therefrom as they are made from non-woven thermoplastic polymeric sheet material having a crystalline structure such as polyethylene terephthalate. The belt 62 is fabricated from two sheets 73, 74 ultrasonically sealed together at 99. Each of the belts 49, 50, 62 is laminated from two layers of film interconnected by a polyurethane resin 72, perforations 75 being punched in. Various polymers such as polyamide, polycarbonate, polyolefine, polyvinyl and vinylidene polymers and copolymers may be used to form the belt. To reduce slippage between a belt and its driving roll a layer of colloidal silica or ground silica is applied to the belt surface. Alternatively a scoring 84a in the form of grooves between the perforations 75 may be provided to increase the coefficient of friction. The ends of a belt may be overlapped and joined ultrasonically (Fig. 7, not shown) or various fastenings used (Figs. 8 to 12, not shown). Resistance to slippage of the belts may be improved by providing protuberances in the form of small hemi-spheres (Fig. 14) or diamond shapes between the perforations (Fig. 13, not shown). One or both surfaces of a belt may be modified to add bulk and increase the absorptive qualities. Fig. 16 shows a belt 137 formed from a sheet of polymer film 136 laminated to a woven textile fabric 135, which fabric may comprise natural and/or synthetic fibres. Fig. 17 (not shown) shows a belt 145 comprising a layer 140 of open-cell plastic foam laminated to a sheet of polymer film 142. Fig. 18 (not shown) shows a belt 147 comprising a sheet 148 of polymer film laminated to a bat 150 of natural or synthetic fibres, which bat may be preformed as by needling, felting or chemical bonding &c. or individual fibres deposited electrostatically on the sheet 148. The perforations in the belts may be square (Fig. 19, not shown) or of other shapes. Reference has been directed by the Comptroller to Specification 1,016,649.

In inking apparatus for a printing machine, the bearing 3 at each end of an inking or distributing roller 2 has a forked part 5 carrying a rotatable spindle 8 having threaded engagement with a pin 9 fixed to a piston 10 having the same operative area at both ends thereof. The piston 11 is mounted in a casing 11 fixed to the machine frame 14, and the bearing 3 is guided by one or more pins 17 fixed to the casing 11. The roller 2 can be moved towards engagement with a coacting cylinder 1 by admitting fluid pressure through a connection 13 to the right end of the piston 10, and a fine adjustment can be effected by rotating the screwed spindle 8 by means of a key inserted through an opening 19 in the casing 11. Application of fluid pressure to the left-hand side of the piston moves the roller 2 away from the cylinder. If the fluid pressure system fails, the roller 2 can still be moved into engagement with the cylinder by rotation of the screwed spindle 8.
