Title: Apparatus for coating web materials
IPC: D21F3/06
Filed: 1960-06-02
Abstract: A machine for coating a web, e.g. of paper has a roller 33, which may have a resilient cover'ing, for leading the web past the edge of a transverse blade 75 which is clamped at 77 against <FORM:0921494/IV(a)/1> plate 45, and pressure means extend along the surface of the blade 75 remote from the plate 45 and are located between the edge of the blade 75 and the clamp, for flexing the blade.  A pair of expansible tubes 90, 91 on a shaft 80 serve respectively to clamp the blade 75 and to provide pressure to flex the blade.  The tubes are expanded by adjustable air pressure (see Fig. 21 (not shown)). Coating liquid, which may be a thermoplastic material, is led through inlets (see Fig. 11 (not shown)) in a plate 60 to pass upwardly behind a gasket 61 to a coating chamber 55. Steam or water may be delivered to a box 44 below the plate 45.  The coating apparatus 40 is mounted on shoes 50 adjustably bolted on tables 51 mounted on a pair of tubes (see Fig. 16 (not shown)), extending parallel to the roller 33.  The tubes may be rotated in unison by hydraulically operated mechanism to swing the coating apparatus 40, including the tables 51, away from the roller 33, and operation of a handle 102 about a shaft 99 pivots spaced hinges 85 on the shaft 80 to withdraw the tubes 90, 91 from the blade 75.  The tubes 90, 91 are adjustable on the hinges 85, the shaft 99 is adjustable relative to the shoes 50, and rotation of a screw 113 at the location of each hinge 85 rotates the shaft 80 (see Fig. 8 (not shown)), to adjust the setting of the blade 75 separately at each location.  The chamber 55 is closed at each end p  by a blade 131, Fig 15, which is adjustable axially of the roller 33 and which carries an elastic member 161 engaging the roller. The blades 131, which diverge in the direction of movement of the web, are also vertically and longitudinally adjustable on screws 133 and are urged by springs 175 against the roller 33.  In the mechanism referred to above for swinging the apparatus 40 from the roller 33, Fig. 16 (not shown), the tubes are interconnected by a linkage which tends to keep the table 51 and the chamber 55 horizontal, and the linkage carries an electric switch which is opened automatically to lower the apparatus 40 should the web choke the gas between the plate 60 and the roller 33 and thus put pressure on the plate 60.  To prevent spilling on the rapid lowering of the apparatus 40, actuation of the switch may be arranged to reverse the motor driving the pump supplying liquid to the chamber 55 or the switch may automatically actuate a solenoid-valve operative to cause liquid to be sucked out of the chamber 55.  Means are described in connection with Figs. 23 and 24 (not shown) for adjusting the position of the box 44 on the shoes 50.  In a modification, Fig. 25, the blade 751 has annular grommets 350 received over the heads 351 of studs 352 mounted in collars 353 adjustably mounted on the shaft 80, rotation of the shaft 80 adjusting the blade 751 as before.

An additional pair of X-ray sources, detectors and rails may be provided, these addition rails along which the additional sources and detectors are moved being orthogonal to the first pair of rails (Fig. 4, not shown). Alternatively the two source/detector pairs may be mounted on a circular track and driven at the same speed and in the same direction around the track as shown in Fig. 5, the body B' being scanned being also moveable relative to the track. By scanning the body section with two X-ray source/detector pairs the signal-to-noise ratio of the information used to reconstruct the image of the body section is improved since the two absorption values obtained for each X-ray path through the body but from opposite directions are averaged. The output signals are processed according to a set of iterative reconstruction algorithms including simultaneous equations for forming a first memory matrix whose elements correspond to the densities of the corresponding areas of the reconstructed image, the processing also including the steps of permanently setting to zero all elements having negative values after each iteration and permanently setting all elements having a positive value larger than a predefined value to the predefined value after each iteration. In addition those elements of the first memory matrix whose values remain substantially unchanged for successive iterations are detected and their values permanently set to their value after the previous iteration. Second and third memory matrices may also be formed from the first memory matrix.

Filed: 1926-08-24
Abstract: 281,360. Sharp, F. L., and Bonnaud, H. M. Aug. 24, 1926. Windmills with adjustable shields, are provided with a vane or tail on the shield relatively movable thereto to cause the shield to become wholly interposed between the vanes and the wind. The shield 9, Fig. 1, rotating on a bracket 10<b> carries a tail 11 which causes it to shield half the vanes against the wind current. The vanes 7 rotate the sleeve 3 in the shaft 10 to drive the lower shaft 5. When the wind-pressure becomes excessive, the pulleys 14 rotate the governor device 13 at a speed sufficient to turn the tail 11 to a horizontal position and the supplementary tail 12 to a vertical position by means of rods 16, 17, 19, causing the shield to swing round so as to completely shield the vanes 7 from the wind until their speed of rotation falls again. In the form shown in Fig. 4, a shield a with a tail f covers half the vanes c and a second rotatable shield g normally lies within it, held by a stop j<1> engaging a pivoted catch i<1> on the shield a. When the wind pressure becomes excessive, a flap e on the shield a is tilted, releasing the catch i<1> from the projection j<1> and allowing the wind impinging on the vanes k of the shield g to move it round until the second stop j engages the second catch, i, in which position the vanes c are completely enclosed. When the wind pressure falls, a spring restores the flap to its vertical position, releasing the second catch i and stop and allowing the wind to rotate the shield g back within the shield a.
