Title: Improvements in or relating to methods of making electrically conducting patterns, such as wiring circuits, coils and the like
IPC: H05K3/28
Filed: 1945-08-23
Abstract: 602,492. Electric heating resistances. FISK, SIR E. T., and SOBY, W. Aug. 23, 1945, Nos. 21544/45 and 9901/46. [Class 39(iii)] [Also in Groups XVI, XXXV, XXXVI and XL(c)] An electrically conducting pattern, such as a wiring circuit for a radio receiver, a coil, an electric heating panel or a condenser, is made on an insulating panel by forming on a metal layer secured to the panel a pattern of resist material and dissolving or etching away the metal not covered by the resist to leave one or more conductors of substantial length attached to the insulating panel. An electric heating resistance is formed on an insulating panel 25. A sheet of tin plated copper foil or resistance metal is hot-pressed to the surface of the panel 25, which is coated with a suitable adhesive. An acidresistant paint is applied to the metal foil through a silk-screen stencil having a pattern of the heating resistance, and the surplus metal removed by etching in a solution of ferric chloride. The acidresistant paint and surplus adhesive are removed, and the pattern 26 may be coated with resistance metal by electro-deposition. The acid resistant pattern may be formed on the metal foil covering the insulating panel by a photographic method. Specifications 327,356, [Class 100(ii)], and 461,275 are referred to.

Filed: 1919-09-08
Abstract: 137,811. Norske Aktieselskab for Elektrokemisk Industri Norsk Industri-Hypotekbank. Jan. 17, 1919, [Convention date]. Electrode furnaces.-An electrode is made by tamping raw carbonaceous material into a metal casing and heating first to a comparatively low temperature, preferably in the furnace in which the electrode is to be used, a part of the heat being produced by current entering the mass through the casing. The electrode may be baked at about 600‹ C. before use in the furnace, to harden the carbonaceous mass sufficiently to withstand expansion stresses. When employed directly in the furnace, the casing is preferably kept comparatively cool until the mass is baked. Fresh lengths of casing can be attached as required and filled with the mass. At starting, some coke may be placed in the furnace to connect the electrode casing to a bottom electrode. When the furnace is hot and the end of the electrode is baked, the coke is withdrawn. The electrode casing b may have holes e for escape of gases during baking, and internal ribs c, with or without right-angled projections, to improve the connexion between the casing and electrode mass.

Title: Improvements in and relating to radar systems
IPC: H01Q3/04
Filed: 1948-08-26
Abstract: 655,582. Radiolocation; automatic gain control. COSSOR, Ltd., A. C., and WILLIAMS, B. C. FLEMING-. Aug. 26, 1948, No. 22561. [Classes 40 (v) and 40 (vii)] A radar system for surveying an area such as the approach zone at an aerodrome of the type wherein a narrow, low-elevation long-range beam is combined with a relatively wide beam of shorter range and greater elevation comprises only one reflector. Two sources or collectors 13 and 14 are arranged respectively at and below the focus of a paraboloid reflector 10 such that the beam associated with the upper is narrow and of low elevation for long-range echoes and has swept-gain control applied and the beam from the lower, which is flared in the manner shown, is wide and tilted slightly upwards for short-range working and has little or no swept gain control. Energy is fed or received via T-R box 26 to wave-guide 25 and thence via a rotating joint 24, 23, to waveguide 22. A switch 18, which may comprise a rotating resonant ring as in Fig. 2 (not shown), or may be electronic, alternately selects wave-guide 11 or 12 for use so that the two beams are operative in turn. The aerial system is carried on a platform 15 which is rotatable by a motor 17 which also drives a Selsyn motor 49 (Fig. 6, not shown), coupled to Selsyn followers 21 and 50. Selsyn 21 drives switch 18 and Selsyn 50 drives two commutators 39 and 44 (Fig. 4), which synchronize the output of a swept gain control circuit with the beam-switching. The swept-gain control voltage delivered from terminal 48 (Fig. 4) is derived from condenser 35 by applying negative-going pulses from the modulator of the radar transmitter to input terminal 29. The biassed diode 32 passes only the peak of each pulse, which charges condenser 35 negatively to a value dependent upon the bias applied to diode 36 from one of two potential dividers 37 or 38. The condenser 35 thus begins for an instant to discharge rapidly through diode 36 which then quickly cuts off and the remainder of the discharge is exponential via one of resistors 42 or 43. The output voltage therefore consists of a steep drop to a maximum negative value depending upon the setting of the slider on 37 or 38 and a subsequent rate of rise depending upon the setting of the slider on 42 or 43, giving curves such as those of Fig. 5 (b) and (c) (not shown). The switches 39 and 44 therefore select the swept-gain control voltage depending upon the settings 37 and 42 for one beam, and of 38 and 43 for the other beam. Since the azimuthal directive axes of the two beams are coincident the echoes can be readily displayed on a single indicator such as a cathode-ray tube having its time base held in step with the rotation of the aerial system.
