Filed: 1927-11-15
Abstract: 281,633. Westinghouse Electric & Manufacturing Co., (Assignees of Beers, G. L.). Nov. 30, 1926, [Convention date]. Thermionic amplifiers.-In order to obtain a straight-line selectivity characteristic in a highfrequency amplifier, the inter-valve coupling comprises a transformer having a primary with a natural frequency lower than the mid-range frequency of the system, and preferably lower than the lowest frequency the system is intended to amplify. The transformer primary is a multilayer coil 40, Fig. 2, and the secondary a singlelayer solenoid 41. The inductance of the primary 12, Fig. 1, is such that at the higher frequencies for which the system is designed, the reactance is capacitative, thus tending to cause negative feed-back at such frequencies. A certain amount of positive feed-back is ensured by the use of a condenser 11, which at the lower frequencies acts . as a neutralizing condenser in known manner. The condenser 11 thus has the double function of balancing both the positive and negative feedback, depending upon the frequency to which the system is tuned. Specification 147,147 is referred to.

Abstract: 636,980. Automatic temperature control systems. GENERAL ELECTRIC CO., Ltd., and HILLIARD, A. G. Nov. 21, 1947, No. 30940. [Class 38 (iv)] In order to compensate for variation in ambient temperature in the heating chamber of a piezo-electric crystal in an automatic control system, an oven, represented by the dotted lines, contains electric heating elements 1 in close proximity to the parts R3 and R4 of temperature variable resistors R3+R5 and R4+R6, the parts R5 and R6 being outside the oven and responsive to ambient temperature. The resistors R3+R5 and R4+R6 are connected with fixed resistors R1, R2 in a Wheatstone bridge circuit, the supply being fed in at terminals 2, and the output controlling the heaters 1 being taken off at 3. Thus an increase or decrease in ambient temperature will result in the bridge balancing, after the increase or decrease, with the resistors R3, R4 at a lower or higher temperature than before the change in ambient temperature. Specification 451,141 is referred to.
Patent GB-446422-A (GB)
Title: Improvements in and relating to the manufacture of artificial filaments, threads, films and the like
IPC: D01F2/28
Filed: 1934-10-29
Abstract: Fibres, filaments, films, and similar products are made from dispersions of secondary cellulose acetate in aqueous and/or alcoholic solutions of halides and/or nitrates of metals belonging to Groups 1, 2 or 3 of the Periodic Classification, by extruding the dispersions through suitable dies, casting them on suitable corrosion resisting surfaces, or coating them on suitable formers and then coagulating them by immersion in water or aqueous solutions. Particularly suitable solutions are calcium nitrate, zinc nitrate and/or calcium bromide.  The inorganic salt is removed during the final washing, causing shrinkage which may amount to 40--60 per cent of the original dimensions.  The shrinkage may be prevented by controlled drying conditions, but is advantageous for tubular bodies such as bottle capsules.  In an example, 50 parts of acetone soluble cellulose acetate is dispersed in a solution of 200 parts of crystalline calcium nitrate in 175 parts of methylated spirit and 25 parts of water by stirring at normal or elevated temperatures.  The solution is filtered, warmed to eliminate dissolved air, cast to form a film on a polished metallic surface or extruded as a filament and coagulated by immersion in water or in dilute aqueous or alcoholic solutions of suitable inert organic or inorganic salts.  The filament or film is washed, and dried slowly; the film preferably under tension to avoid shrinkage.  In another example, capsules are formed from a dispersion as described above by dipping a suitable former and coagulating on the former.  The formed capsules are removed, washed and stored ready for use either in pure water or in water containing a plasticizer, e.g. 3 per cent of triacetin.  Or they may be stored in closed containers, evaporation being avoided.  Dyestuffs or pigments, e.g. gold bronze powder, may be added to the original dispersion or the formed articles may be dyed.  According to an example in the Provisional Specification, the cellulose acetate dispersion is formed by evaporation of the water and alcohol into irregular sheets which are compressed to a block from which sheets may be sliced and immersed in water to precipitate the cellulose acetate and convert it from a sol to a gel.

Abstract: 1310703 Telegraphy; identification of transmission speed COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT ALCATEL 25 June 1970 [27 June 1969 24 Dec 1969] 30981/70 Heading H4P The Specification discloses a circuit for distinguishing between signals identifying the speed of a following transmission, i.e. 50 baud or 200 baud on say a teleprinter network in order that calls at the higher speed may be charged at an appropriate rate. A 50 baud call signal, identified by positive voltage on line A, following negative potential, causes a diode d2a to become conductive hence a relay AP is energized and contacts ap supply positive voltage to point E1 causing a capacitor C to discharge through a resistor R2a thus blocking a transistor T1a during this time. Diode d1a is blocked by positive voltage on line A hence the resistors R3a, R4a are currentless hence the base of a transistor T2a is at a positive potential as well as the emitter through diodes d3a, d4a, hence T2a is also blocked. A diode D6a is blocked during this time hence transistor T3a is also blocked. After the capacitor C is discharged, T1a becomes conductive but this has no further effect. A 200 baud call is identified by a positive voltage of say 80 m. sec. followed by a negative pulse of say 40 m. sec. As the discharge time of capacitor C is longer than 80 + 40 m. sec. this is still discharging when the negative pulse is received hence by conduction of diode d1a transistor T2a becomes conductive hence operating a relay DC which is held over its own contact dc until contacts ap open, and which also energizes a higher call rate circuit (not shown). The volt drop across resistors R5a, R6a also renders transistor T3a conductive which holds relay AP energized.
