Title: Improvements in or relating to a method of and apparatus for feeding wire and the like to a roller to form netting
IPC: D04H3/002
Filed: 1962-12-31
Abstract: Threads or wires are fed from bobbins 2, Fig. 1 (not shown), through a laying device 7 which causes them to adopt a recticular configuration as they pass between a pair of rollers 5, 9 and between two layers of paper 10, 11 fed to the rollers.  The laying device comprises a chain or series of chains 20 Fig. 4 (not shown), having rollers 22 provided with bores through which the threads or wires pass.  The chain 20 is floatingly supported on a plate 24 by a further chain 19 which drives the chain 20 to cause it to revolve round the plate 24 such that the threads or wires are caused to pass from one end of the roller to the other and back again.  A motor 31 serves to drive the bobbin carrier 1, the laying device 7 and the take up rollers 5, 9 simultaneously.  The ratio of the speed of the chain to that of the speed of the net formed can be varied whereby the angle of inclination of the intersecting threads forming the diagonal network is also varied. The net formed serves for the reinforcement of the paper webs. The mesh formed can also be secured by being welded at the points of intersection.  Any appropriate types of thread can be used, for example, threads of textile material, plastic, glass or metal.

In another embodiment Fig. 3 (not shown) poppet valves are operated by cams arranged so that one set of cams act on a portion of the rocker arm which is on the opposite side of the pivot from the valve-operating end and another set of cams act on a rocker arm between the pivot and the valve operating end. In modifications the end of the rocker arm may be arranged to co-operate with a valve engagement arm having an internally-radiused elongated slot or in the form of an adjustable split-reel arm or adjustable socket. In further modifications the pivot ends of pairs of rocker arms are forked or hinged together or cranked and arranged side by side on the rocker arm shaft. Lubrication. Oil is supplied through ducts 2 to cams 22, 23 and end 19. Oil directed to grooves 27 from thrower washer 34 spills over to lubricate the driving gear.

Abstract: 1,150,238. Decorative article. M. F. SALVADORI. 4 Nov., 1966, No. 49466/66. Heading B6G. [Also in Division B5] A decorative article is prepared by applying to a transparent sheet a layer of a transparent glue, injecting a fluid into the glue so as to form stable bubbles, and allowing the glue to harden. The transparent sheet may be either rigid or flexible, e.g. glass or polymethyl methacrylate. Both the sheet and the glue may be colourless or alternatively a coloured glue may be used, or the glue may be painted when it has hardened. The fluid may be a gas, e.g. air, which may be injected into the glue from the side using a syringe. The glue may be applied to the sheet in strips, the fluid being injected into each strip before the next strip of glue is applied adjacent to it. The fluid may be a transparent cement which hardens in position in the bubbles but does not mix with or dissolve the glue. The bubbles in the decorative articles catch the light, and give attractive rainbow-coloured effects. A panel comprising two of the decorative articles in which the transparent sheets are rigid and flat and parallel to each other, with the layers of glue between the two sheets, may be formed. A diffraction grating may be positioned in this panel mid-way between, and parallel to, the two transparent sheets. The panels are suitable as translucent partitioning in buildings.

A pair of probes 20, Fig. 1, mounted on frame 8 brush against the root crops as the machine advances; misalignment of the machine is corrected by either one of the probes being displaced by a root, this in turn operates a hydraulic spool valve 24 causing a hydraulic ram 14 to rotate the ground engaging wheels 4, 5 about a pivot 7 until the machine is correctly aligned. The spool valve is spring biased to a neutral position. The topping apparatus 28 mounted on frame 8 is driven by a gearbox 30, via a cordon shaft 32, shaft 34, chain drive 36 and cordon shaft 38. In a second embodiment, Figs. 3 and 4 motion of the probes 42 which redisplaced vertically by the roots is detected by a proximity switch 46 which is in circuit with a solenoid spool valve 40 causing the ram 14 to operate as before. Hunting is prevented by two further proximity switches 48 placed on either side of the axle 6, these operate the solenoid spool valve to straighten the wheels after alignment.

(NH 4 ) 2 SO 4  is recovered from the waste-water stream from α,#-mono-olefinically unsaturated nitrile production by treatment under autogenous pressure, optionally in the presence of added ammonia, at a temperature of 100- 300‹ C. which is dependant on (i) the weight per cent concentration of ammonium sulphate (usually 6 to 30%) present and (ii) whether any ammonia is added, to decrease the content of cyanic compounds. After heating, the pressure is reduced to atmospheric, and ammonium sulphate (fertilizer grade, e.g. 97À5% pure) may be recovered by crystallization from the slurry produced from the partially evaporated (and previously treated as prescribed) effluent stream. The term " cyanic compounds " means those compounds containing a CN-group that are capable of forming CN- ion detectable by the analytical method described in, e.g. ASTM D-2036; and when ammonia is added to the waste water stream, it is added in a ratio of 0À8-50 gm. ammonia per kgm. of waste water stream.
