IPC: H01B1/00
Filed: 1957-05-30
Abstract: 845,453. Forming patterns; printed circuits. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 19, 1958 [May 30, 1957], No. 17151/57. Class 93. [Also in Groups XVI and XXXVI] A process for forming a conductive film on an insulating support comprises the steps of applying to the support a resist of polyvinyl alcohol material, forming the resist into a stencil by photographic means, covering the stencil with a film of the conductive material in such a manner that it adheres to the support through the stencil, and removing the stencil to leave a thin film of the conductive material in the desired configuration on the support. In the embodiment described, a resistive element in the form of a finely meandered track of metallic oxide is applied to a glass plate. The plate is first ground to a dull finish on the side opposite to that on which the resist is to be applied, and then, after cleaning, covered on the unground side with a photo-resist for instance polyvinyl alcohol/bichromate combination. The resist is covered with a positive transparency of the required configuration of the track, and then exposed to ultra-violet irradiation. After developing the resist to remove the unexposed parts, a coating of oxides of tin and antimony is applied over the stencil by spraying it with a mixture of respective chlorides in a medium of dilute hydrochloric acid, the support being at a temperature of about 500‹C. The stencil with its overlying coating is then removed by treatment in boiling sodium hydroxide. In a modification of the process, the conductive film may be applied by heating the glass support with its prepared stencil to between 400‹C. and 600‹C. and rapidly submerging it in a solution comprising chlorides of tin and antimony in dilute hydrochloric acid. Other methods of depositing the film, such as spraying, vacuum deposition, electro-sputtering and printing may be used.

[Class 38 (iii)] In a Ward-Leonard set, the resistance in the exciting circuit of the generator is abruptly increased at a predetermined instant in order to reduce the motor speed to an intermediate value between the normal running speed and the minimum operating speed preparatory to stopping or reversing, the said intermediate speed being dependent upon the speed at which the reduction is initiated, the resistance being further abruptly increased in order subsequently to operate the motor during a predetermined number of revolutions at the minimum speed. As shown, the motor M driving a machine-tool such as a planing machine is fed by a generator G having in its field circuit resistances Rg, 26 and 27, the arrangements for reversing not being shown. The three switches 28a, 18a and 29a are operated in this sequence during one stroke of the machine drive by tappets engaged by a moving member on the machine tool. At the first of these operations switch 28a moves to contact c, on the second resistance, Ry is cut out, and on the third the circuit is opened. The resistances Rg and 26 are of equal value so that if the slide on Rg is at the right-hand end corresponding to minimum speed, actuation of switch 28a has no result. There may be a fourth tappet whose function is to apply full field to the motor and the system may be used in conjunction with motor field control, e.g. as described in Specification 625,565. Specification 626,613 also is referred to.
