Abstract: 1413713 Enamelling iron surfaces BAYER RICKMANN GmbH 13 April 1973 [15 April 1972] 17834/73 Heading C1M A process for the production of a protective enamel layer on a substrate comprising iron comprises applying to the substrate an enamel slip containing powdered aluminium and/or a powdered aluminium alloy in an amount 5- 75% by weight of the sum of the other solids of the slip, drying the slip, and storing the resultant composite substrate and slip at a temperature of 800-900‹ C. Part of the aluminium and/or aluminium alloy, e.g. 50% by weight, may be replaced by an equal weight of aluminium oxide. The particle size of the powdered aluminium or aluminium alloy may be 0À01- 0À10 mm. and this powder may be coated with a thin coating of oxide to retain even distribution in the slip. Uniform dispersion may also be retained by the addition of an oil or wetting agent. Further additives present in the slip, besides the frit, are clay, boric acid and sodium nitrate. Particularly suitable frits comprise in per cent by weight 33-50% SiO 2 , 0-25% B 2 O 3 , 15-35% Li 2 O+Na 2 O+K 2 O, 0-25% Al 2 O 3 +TiO 2 , 0-15% CaO+BaO, 0-10% ZnO + P 2 O 5  + ZrO 2 , 0-5% CoO + NiO + CuO, 0-7% F-, together with amounts of MgO, MnO, Sb 2 O 3  and Fe 2 O 3 .

Abstract: 635,018. Wave-guides; generating highfrequency oscillations; radio receiving apparatus. GENERAL ELECTRIC CO., Ltd., and ROBERTSHAW, R. G. July 8, 1947, No. 18078. [Class 40 (v)] [Also in Group XL (b)] Apparatus for harmonic generation or mixing at very high frequencies comprises a wave-guide of uniform cross-section, one part of which is filled with material of higher dielectric constant in which a crystal contact is effectively embedded, and the other part is filled with material of lower dielectric constant. As a harmonic generator, the fundamental frequency is fed into the section 2 of the guide filled with material 3 of higher dielectric constant, such as vitreous quartz, and the harmonic oscillation is taken from the section 4 of the guide having air as a dielectric. A germanium or silicon crystal 8 is mounted in a metal support 6 with a plane contact face flush with the wall of the guide, and a platinum whisker 9 passes through a hole 5 in the dielectric 3. The whisker 9 fits closely in the hole 5 and is carried by a metal rod supported by insulating bushes in a filter stub 12. A filter ditch 13 is provided in the input guide. The dielectric 3 is tapered to provide matching between the sections of the guide. Two frequencies may be mixed by feeding the higher frequency to the guide containing material of lower dielectric constant, and taking a difference frequency output across the crystal contact. A modulated wave with a carrier frequency equal to a harmonic frequency of the frequency which is fed into the guide containing material of high dielectric constant is demodulated by feeding into the section of guide with air dielectric and taking off the modulation across the crystal contact. The guide, or part of the guide, may be formed as a metallic coating on the dielectric.

In a modification, Figs. 14 to 18 (not shown), the member 25 is controlled by a bar running the length of the switch and rocked by the clutch magnet. The wipers travel over different rows of terminals during the go and return movements, the wiper-carrying part being moved in relation to the rest of the wiper carriage by a rack and pinion arrangement, Fig. 13, controlled by a shaft 89 which is moved through 90 degrees when the carriage reaches the end of its travel in either direction and begins to reverse. Strips are provided graduated in wiper positions along both edges, one or other of two pointers carried by a common arm being on view according to the direction of travel. Driving arrangements.-A double-worm is formed on the main shaft 58 and co-operates with a projection on the wiper carriage to make it move to and fro along a guide bar 11. The shaft 58 has keyed to it a ribbed cone 62 which is forced against a driving disc of leather &c. by a spring 64 when the clutch-magnet is energized, the forked end 71 of the armature of the latter, which normally holds the driving cone against a rubber stop 68, being then moved clear so that it is not in engagement with the cone when the switch is being driven. Home contact springs.-These are carried in a separate moulding which is forced into the main frame moulding and are operated by rotation of a shaft 12. This may take place at any position of the wiper carriage according to the position of an adjustable part 114.
