[Also in Division H1] An etching process comprises applying a protective layer to a surface, using a first photomask and photoresist layer in order to accurately define selected areas in the protective layer by etching, removing the photoresist, forming a second photoresist layer, and then using a second photomask having images corresponding to only some of the selected areas and positioned in crude alignment with these areas for an etching step in which the remainder of the selected areas are protected. The invention is particularly applicable to the manufacture of semi-conductor devices. A first embodiment, Figs. 1 to 4, and 4a-4d (not shown) involves 'the steps of: (a) providing a silicon wafer with a protective layer of ethyl silicate or silicon dioxide and a photoresist layer, (b) exposing the photoresist through a photomask which has images of all the areas which are required to be etched, (c) developing the photoresist and etching with HF to a predetermined depth in the protective layer, (d) removing undeveloped photoresist and covering the protective layer with a second photoresist, (e) crudely aligning a mask, which has only images corresponding to a proportion of those on the first mask, over the etched areas, (f) exposing through the second mask, developing and etching with HF to remove all the protective layer in the desired areas, (g) performing a diffusion, (h) removing undeveloped photoresist, growing a protective layer overall and covering with a third photoresist, (i) exposing this photoresist through a crudely aligned photomask having images corresponding to the remainder of the images on the first mask, (j) repeating step (f) with the third mask. In an alternative embodiment, Figs. 5 to 7 (not shown), the protective layer is completely etched through in step (c), undeveloped photoresist is removed and a new protective layer grown before the covering with a second photoresist. The method can be extended to a series of photoresists and masks, in which all subsequent masks need be only relatively crudely aligned with the first, i.e. to within 0À0001 inch).

A welding control system comprises a pulse generating apparatus which includes means (AT) for generating phase displaced alternating voltages having progressively increasing amplitudes; rectifying means (RF), for generating from the alternating voltages, unidirectional' voltages which also have progressively increasing amplitudes (1, 2-6) and means (SW) to combine the voltages (1, 2-6) so as to provide a pulse having a mean increasing amplitude. The circuitry is detailed in Fig. 1 wherein six autotransformers 12 having differing tappings 13 provide six alternating voltages of progressively increasing amplitudes. Each of these voltages are fed to a separate thyristor 14 so as to be rectified to provide separate unidirectional voltages of progressively increasing amplitudes. The unidirectional voltages are added sequentially by means of relays 26 associated with each of the thyristor circuits so that at a terminal 15 a voltage waveform appears of the form shown at PB in Fig. 4. Surge protection is provided by the elements 18, 29 and an R/C filter 19. The apparatus may be arranged to have a waveform having a longer or shorter time base and/or a greater or lesser number of unidirectional voltages therein. A welding operation is controlled by circuitry which includes a large number of relays which are effective, inter alia, to close contact 26a to initiate the welding operation. The control may be such that a welding operation is terminated by a waveform which has a mean decreasing amplitude.

The angle of jump, i.e. the angular difference between the set angle and the angle of departure, of a projectile leaving a barrel is determined by recording on a common film strip against a time scale the following three steps. (1) The angle of deflection of a first beam of light 3 projected initially perpendicularly on to a plane mirror 6 fixed to the barrel 2 adjacent the barrel exit with its plane perpendicular to the barrel axis, the beam 3 being reflected into the convex 1 by a mirror 7. (2) A second beam of coherent light 15 is arranged to pass in front of the barrel 2 normal to the barrel axis a distance from its exit equal to the length of a projectile, the beam having a path to the camera via mirrors 16, 17. The film records the interruption of the beam by a projectile leaving the barrel. (3) A third beam of light 8 from a laser 9 is focused on to a vertical slit 18 at the barrel exit, the beam being perpendicular to the barrel axis, and the diffraction pattern formed by the slit being recorded on the film with the aid of mirrors 11, 12 and magnifying system 20. Thus step (1) shows against timing markings the angle of deflection # of the barrel. Step (2) records the moment of emergence of the projectile and step (3) records deviation of the diffraction pattern which enable the cross velocity V t  of the barrel to be evaluated. From those graphs can be calculated the actual angle of departure α and the projectile velocity V.

Said wheel mounts 22 are each secured to a shaft 21 pivoted by a sleeve 20 to one end of a spacer tube 18, and to a said piston-rod. When a different sized tyre is fitted to the apparatus shaft 21 turns to accommodate the new tyre on the drum, and consequently the roller 50 moves within slot 51 to automatically maintain the line of action of the force through the axis of shaft 2. The piston 41 is driven by fluid supplied down a fluid pressure line 55 from a fourway valve 56. The valve is supplied by a line 60 from a source of constant pressure. To apply or remove a tyre from the wheel mount the wheel 15, formed by two side plates 16, 17 separated by said spacer pipes 18 and stabilized by radially extending stiffeners 32, 33, is rotated by means of a gear motor 37 mounted on top of an enclosure structure 33, a chain 36, and a sprocket wheel 35 incorporated in said wheel 15, to bring a selected wheel mount into position 2211. In this position the wheel is readily accessible to an operator positioned within the enclosure 38 without risk of injury caused by any of the other tyres under test bursting. A push-button 61 may then be actuated within enclosure 38 to cause solenoid 62, corresponding to the "advance" side of the fourway valve 56 to apply fluid under pressure to urge the wheel under test away from the road drum to enable the operator to remove or otherwise work on that wheel.
