Abstract: A composition is formed by heating a mixture comprising an acrylonitrile-acrylic acid copolymer as its alkali metal salt and an alkali metal silicate in proportions such as to form a homogeneous aqueous solution on admixture with water.  In one embodiment an aqueous solution of the copolymer, obtained by polymerization of the monomers in an aqueous medium followed by neutralization of the resulting solution with alkali, is added to, e.g., sodium or potassium silicate, the mixture being boiled under reflux and NH3 being evolved.  The solution produced is used as a glue, or as a binder, in coating compositions in which inert fillers such as heavy metal oxides, e.g. TiO2 (Examples II and III), amorphous silica (Example II), kaolin (Examples II and III), talc or asbestos (Example III), clays and diatomaceous earth are included. In Example IV a fungicide comprising a mixture of sodium pentachlorophenate and tetrachlorophenate is also added to the copolymer binder, along with a pigment (an iron, cadmium, chromium or titanium oxide). The compositions are applied to various substrates (see Division B2).ALSO:A coating composition comprises a binder formed by reacting an alkali metal silicate with an acrylonitrile-acrylic acid copolymer as its alkali metal salt.

Abstract: 608,506. High-frequency transmission lines. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Nov. 21, 1945, No. 31409. Convention date, July 25, 1944. Drawings to Specification. [Class 40 (iv)] [Also in Group XL (c)] An aerial array comprising a plurality of dipoles fed effectively in parallel is mounted on a metallic mast with a cylindrical longitudinal bore through which a central conductor extends coaxially; the central conductor and the wall of the bore forming the feeding transmission line. In order to avoid excitation of the line in undesirable modes, #/2 times the sum of the diameter of the bore and the diameter of the inner conductor must be less than one wavelength of the frequency of operation. Tubular spacers of insulating material are used in the line and are made half-a-wavelength long at the velocity of propogation through the insulating material in order to prevent reflection. In order to match the comparatively low impedance of the aerial array to that of the line a conductive sleeve one-quarter of the wavelength long engaging the inner conductor and cooperating with the wall of the bore to form a line section with an impedance less than that of the line is used. Owing to the impedance inversion characteristics of quarter-wave lines this section operates as a transformer to provide the desired matching.

Abstract: 1,196,763. Shift registers. GENERAL ELECTRIC CO. 10 July, 1967 [26 Oct., 1966], No. 31691/67. Heading G4C. [Also in Division H3] A combined logic and bi-stable circuit suitable for use in a shift register comprisees a bistable element to which " set " pulses are fed from a logic circuit and " reset " pulses are applied from a clock circuit, the " set " pulses overriding the " reset " pulses when both are present. As shown, when all the logic inputs A, B, C, D are " up " the positive clock pulse applied through transistor 47 to bases 24 and 35 does not render transistors 13 and 17 conducting but through the direct path 46 the clock pulse switches the tunnel diode 40 to its low-voltage state. If both A and B or C and D are " down " the common emitter potential is lowered and the clock pulse is sufficient to render transistor 13 or 17 conducting so that the common emitter current is drawn from the tunnel diode circuit. This overrides the direct clock pulse and the diode is switched to its high-voltage state. Capacitor 28 across the emitter resistor enhances the initial switching current and also slows the switching to prevent false operation of succeeding circuits when the signal changes during the clock pulse. The circuits may be connected in cascade to provide a shift register with forward and reverse shifting (Fig. 6, not shown).
