Abstract: 1374468 Metal gauze PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 26 Oct 1971 [29 Oct 1970] 49675/71 Heading D1K [Also in Divisions B3 B6 C7 and G2] In a method of manufacturing a silk-screen printing mask which consists of a metal wire gauze whose meshes outside a pattern to be printed by the mask are closed by a metal design, bonded to the gauze, a metal coating is applied to a support the adhesion between the coating and the support being. so poor that the support can be readily separated from the metal coating, a metal design in a negative of the pattern is applied onto the metal coating, then the support bearing the coating and design is placed on a piece of wire gauze so that the design is in contact with the gauze, the assembly is heated for such a time and at such a temperature that the metal design is bonded to the wire gauze as a result of diffusion, the support is removed from the assembly and the metal coating is removed from the silk screen printing mask. In the particular example, chromium or a chromium-nickel alloy was vapour-deposited in a layer on a flat copper plate and the layer then oxidised. This formed the support. A second layer of similar composition forming the metal coating was deposited on the oxidised layer by cathode sputtering or vapour deposition. A photoresist layer in a "positive" of the pattern was applied thereto and then a nickel layer and subsequently a copper layer were electro-deposited on the exposed metal coating to form the metal design and the photoresist was removed. The support coating and design were laid on a wire gauze of copper plated chromium-nickel steel and heated for 1 hour at 800‹C in' a hydrogen atmosphere until bonding took place after which the plate was removed and subsequently the metal coating removed from the design.

The platform 6 can be moved from a vertical inoperative position, Fig. 1, in which it is held by latches 27 to a downwardly inclined ground engaging position. Fig. 4 with a lowering movement between the vehicle floor 4 and the first contact with the ground with the platform horizontal. A single acting hydraulic cylinder 15 extends between a pivot point 18 on the arm 8 and an end pivot 19 of a rocking lever 20 to the other end of which the arm 8 is pivoted at 12 and which is itself pivoted at 21 intermediate of the points 12, 19 to the structure 5. An adjustable stop 23 limits the movement of the arm 20 and prevents its backward movement beyond the vertical. From the position of Fig. 4 extension of the cylinder 15 first brings the stop 23 against the structure 5 and thus brings the platform 6 to the horizontal postion. Further cylinder extension then raises the platform held horizontal by extension of the arm 8 being prevented by a latch 25 up to the vehicle floor 4 at which point if unlatching means 26 is operated to release the arm 8 to allow its extension so that further extension of the cylinder 15 raises the platform to the vertical postion, Fig. 1. In a modification the pivot 18 is moved to a point on the platform 6 between the pivots 9, 10 thus removing the need for a latch 25. The stop 23 may be adjustable by being connected to the lever 20 by a further hydraulic cylinder.

As shown the combiner 17, the objective 18 and the graticule 19 are rigidly mounted in an objective holder, the graticule lying in the focal plane of the objective. This assembly is rotatable about the optical axis of the microscope. A condenser 14 and the divider 15 are rigidly mounted in a condenser holder. The graticule 18 is mounted in the condenser holder so as to be rotationally and translationally movable within the focal plane of the condenser 14. The condenser holder is rotatable about axes perpendicular to the optical axis of the microscope. Initially adjustment of the objective and condenser holders is made without reference to the graticules in order to optimize an interference pattern imaged in the back focal plane of the objective. The graticule 13 only is then moved until it is imaged in precise register with the graticule 19. The plate 13 is locked in this adjusted position relative to the condenser, so that a subsequent user may reproduce the desired adjustment by rotation of the objective and condenser holders to achieve accurate registration of the graticules, without obscuring the interference pattern. In a modification, the graticule 13 is fixedly disposed with respect to the beam divider 15 in the optimum position so that the initial adjustment of the plate 13 does not take place. The graticule may then be formed on lens surfaces.
