Material in web form, including a reinforcement in the form of an assembly of cross-laid (as distinct from woven) threads, is made by moving the longitudinal threads in lengthwise direction, applying to them a liquid material capable of being subsequently set to render it permanent, in excess of the quantity required to fill the spaces between the threads, laying transverse threads on the longitudinal threads, advancing this assembly, whilst supported and enclosed between two carrier webs, into a region where it is treated to set the liquid, and removing the carrier webs. As shown, carrier webs of regenerated cellulose 10 are fed downwards over the distance-piece 19 and opposite faces of a rectangular former 14. Warp threads 12 pass over guide-rollers 13 and are laid on the carrier webs. An excess of polyester resin 20 is applied by the transfer rollers 17. A rotating annular platform 21 winds weft yarns 23 around the warps. Second carrier webs 24 of regenerated cellulose are fed to the combiners 26, and the wefts slit by means 27. The assemblies are then fed to zones where the polyester resin is cured by heat and ultra-violet light from the lamps 30. The carrier webs are then stripped off and rolled up at 31 and 32, and the reinforced web material at 34. In Fig. 2 (not shown), the resin is partially cured by ultraviolet light before slitting. In another modification, a second layer of warp threads is laid on top of the wefts. The threads may be of glass or of high polymers, e.g. nylon, and may be of two or more different kinds, e.g. alternate threads of glass and high polymer in both warp and weft. The binding liquid may be a mixture of an unsaturated polyester with styrene or methyl methacrylate. Specification 806,912 is referred to.

Abstract: 1,077,051. Measuring temperature electrically. TESLA, NARODNI PODNIK. Jan.14, 1965 [Jan.17, 1964], No.1660/65. Headings G1A and G1N. In order to measure ambient temperature or radiation, the power losses in an exposed ferroelectric element are measured by its damping effect on a parallel tuned circuit. As shown (Fig.1), a parallel resonant circuit 2, 3 tuned to a frequency f o , is forced into free oscillation by a pulse generator 1 operating at a lower frequency f imp  . The natural damping factor of the tuned circuit 2, 3 is measured by a meter 11 arranged to determine the average value of the free oscillations. In parallel with the tuned circuit is a ferro-electric element 5, and the change in the damping of the tuned circuit is indicative of the power losses in the element 5, which is indicative of the ambient temperature. The ferro-electric element may be inductively coupled to the tuned circuit, or directly connected to it. The initial temperature of element 5 may be raised by current from a generator 7 operating at a different frequency. In an embodiment Fig. 2 (not shown), the average and peak values of the damped oscillations are measured and their difference determined.
