Automatic exchange systems and apparatus.- A selector with more than one wiper set and corresponding contact banks is provided with separate inlets to each wiper set and a further common inlet to its operating magnets. Access is had to the selector either over different groups of preceding switches, there being as many groups as there are wiper sets in the selector, or over a single group of preceding switches in which case the wiper set used depends on the position to which the preceding switch is set. In the first case, the preceding switches have commoned outlets to the operating magnets of the selector, and in the second case these magnets are controlled over an outlet common to the positions of the preceding switch corresponding to the independent outlets to the different wiper sets of the selector. The invention is described as applied to the testing arrangements of an exchange with connectors having two hundred outlets to private branch exchange lines, testing connectors having two wiper sets X, Y, Fig. 1, and banks P, Q being accessible from the test clerk's distributor, the banks A and B of which give access to the operating magnets M and the wiper sets respectively. The contacts in the bank A corresponding to those in the bank B leading to the wiper sets X, Y are commoned to the outlet to the operating magnets M. The bank P may be connected to lines with directory numbers and the bank Q to auxiliary lines having no directory numbers, the wiper set Y being accessible over a spare contact set of the test distributor. If no spare contacts are available an auxiliary distributor D, C, Fig. 1<a>, is provided giving access to the wiper set Y and the common control inlet. The test connector is controlled from the distributor to select any numbered or auxiliary line as described in Specification 171,433.

Title: Improvements in or relating to the treatment of textile and other articles with acidylating agents
IPC: B29D7/00
Filed: 1940-01-31
Abstract: 538,520. Cellulose derivatives ; treating textiles with liquids. MONCRIEFF, R. W., and BATES, H. Jan. 31, 1940, Nos. 1901 and 8258. [Classes 2 (ii) and 15 (ii)] Textiles, foils, films, and the like, are subjected to the action of esterifiying agents containing radicals of poly-carboxylic acids and higher aliphatic monocarboxylic acids. The higher aliphatic monocarboxylic acids are those containing at least 6 carbon atoms, e.g. caproic, caprylic, lauric, or palmitic acid. The polycarboxylic acid may be adipic, tartaric, phthalic, succinic, citric, tricarballylic, α-#-γ- butane tricarboxylic, or α-#-γ-#-butane tetracarboxylic acid. The treatment improves the crease-resistance, wearing properties, and breaking strength of the materials. The materials may be rendered water-proof. The melting point and safe-ironing temperature of cellulose derivative materials is raised. The process is applicable to materials made of cotton, linen, regenerated cellulose, cellulose organic derivatives, wool, silk, synthetic nitrogen-containing compounds such as polyamides, synthetic hydroxy-containing compounds such as partially saponified polyvinyl acetate or partially saponified vinyl-acetate-vinyl chloride co-polymers. Yarns or fabrics may be treated. The esterifying medium may comprise a non-solvent medium containing a liquid non-solvent and a low concentration of the mixed anhydrides of a lower fatty acid and a polycarboxylic acid and of a lower fatty acid and a higher aliphatic monocarboxylic acid. The mixed anhydrides may be prepared by heating a medium containing a non-solvent for the articles to be treated and a mixture of a lower fatty acid and the anhydrides of the other acids or a mixture of these acids and a lower fatty acid anhydride. Introduction of the higher monocarboxylic acid radical need not be effected at the same time as the polycarboxylic radical. The articles may first be heated with a mixture of a lower carboxylic anhydride and a polycarboxylic acid, and subsequently with a mixture of the anhydride and a higher monocarboxylic acid. As non-solvent diluent there mav be used toluene, xylene, mesitylene or kerosene. During the esterification any lower fatty acid present or formed is preferably distilled off and thus removed from the esterifying medium.

Abstract: 634,577. Resistance measurements. LABORATOIRES RADIOELECTRIQUES. Jan. 22, 1947, No. 2056. Convention date, Jan. 22, 1946. [Class 37] Fig. 2 shows apparatus for measuring the R.F. resistance of a piezo-electric crystal 1, which is energized at its resonant frequency from the variable frequency generator 3 through resistance 2, the voltage across which is fed to amplifier detector 6. A voltage of the same order is fed to amplifier detector 7 from potential divider 8, 9 across the crystal, and the rectified outputs supply potentiometers 10, 11, between the sliders of which a galvanometer 12 is connected. The voltage across and current in the crystal are in phase when the generator frequency is tuned to the crystal frequency, which is indicated by a straight line trace on a C.R.O. 13, the deflection plates of which are respectively fed with the unrectified voltages from amplifier-detectors 6, 7. Initially, a calibration resistance 4 is substituted for the crystal by switch 5, and potentiometer 11 is adjusted to zeroize galvanometer 12 while potentiometer 10 remains in a reference position. The crystal is switched in, potentiometer 11 is left unaltered, and potentiometer 10 is adjusted for balance. The R.F. resistance of the crystal is a function of the calibration and measurement values of potentiometer 10 and thecalibration resistance. A mathematical analysis is given. The amplifier-detectors have phase correctors which are adjusted during calibration. In modifications (Figs. 3, 4; 5 not shown), the generator and the amplifierdetectors are returned to a common earth, the generator is frequency-controlled by the crystal under test, and frequency changers having a common variable local oscillator may be interposed between the crystal and the amplifier detectors for testing crystals of differing frequencies.
