Title: Process for the production of furnace black
IPC: C09C1/50
Filed: 1974-01-25
Abstract: 1453138 Carbon black DEUTSCHE GOLDUND SILBER-SCHEIDEANSTALT 25 Jan 1974 [5 Feb 1973] 03485/74 Heading C1A A process for the production of carbon black in a furnace fed with oil feedstock, fuel gas and combustion air in which the combustion air is introduced tangentially or axially through the end wall of the reactor, the oil feedstock is atomized with gas and introduced through a device in the central portion of the end wall also provided with at least one adjustable opening for the fuel gas between the air inlet and the oil stock inlet characterized in that the pressure of fuel gas is adjusted to and maintained at a value of up to 5 atmospheres, preferably 0À1 to 3 atmospheres the value being selected according to properties, yield and/or output required. The surface area of the carbon black is increased by increasing the fuel gas pressure without changing the rates of feed of oil feedstock and combustion air. The yield of carbon black is increased by increasing the fuel gas pressure without any change in the reactor temperature or the surface area of the carbon black. The reactor temperature and surface area of the carbon black may be kept constant by reducing the combustion air/oil feedstock ratio. The DBP number of the carbon black may be increased by increasing the fuel gas pressure. A suitable apparatus comprises a reactor and a burner arranged centrally in the end wall thereof. A two-component spray nozzle from which the feedstock, atomized with air, issues is situated at its tip. Outlet openings for the fuel gas are situated in front of the two component spray nozzle on the circumference of the burner. The openings may be a number of holes or preferably an annular gap of adjustable width.

Class 120(3) [Also in Group XI] In an apparatus for heating yarns, especially for the production of high bulk yarns by false twisting thermoplastic filaments and setting them by heat, a closer control of the final temperature is obtained by using a thermostatically controlled preheater element to heat the yarn to a temperature near to but below the required temperature and thermostatically controlled auxiliary heater following in the direction of travel of the yarn to heat the yarn up to the required temperature. The heating sections may overlap. The yarn 4, Fig. I, passes through preheater section A and auxiliary heater section B. To achieve a yarn temperature of 220‹C. from a starting (ambient) temperature of 200‹C. the preheater element supplies 92À5-97À5% of the total heat supplied to the yarn. In another form the yarn passes through casing 6, Fig. 5, and its made to run in direct contact with the heating elements. If the yarn is to be heated to 231‹C. 10À5 the preheater section supplies 95-99% of the total heat required. Specification 745,337 is referred to.

Abstract: 553,847. Valve amplifying circuits. STANDARD TELEPHONES & CABLES, Ltd. April 3, 1942, No. 4477. Convention date, Dec. 28, 1940. [Class 40 (v)] A multi-stage amplifier is provided with two or more stabilizing feedback paths embracing the same group of two or more amplifying stages. The arrangement is preferably such that the total feedback is constant over the operating range which may occupy a wide band. In this way the limitations imposed by stray capacities on the amplifier performance as disclosed in Specifications 514,567 and 542,175 may be avoided and each of the feedback paths is principally effective in a different portion of the frequency range. The Figure shows an arrangement in which a common impedance network Z3 predominating at high frequencies is included in the cathodes of amplifying stages 1, 3 and a network Z4 predominating at low frequencies is common to the output and input circuits. A smooth transition from series to cathode feedback is obtained by proportioning the equivalent networks so that inductance 10, capacity 14 equals the product of resistances 11 and 15. Bias may be provided by resistance 12 through leak 17 while resistance condenser combination 18 may provide a low frequency adjustment of the feedback. Circuit elements in the networks Z3, Z4 may be provided to compensate for the rising attenuation-frequency characteristic of a preceding co-axial conductor cable. In a modification a series feedback coupling is combined with a shunt feedback connection which may extend from the last stage anode to the first stage grid, Figs. 6 and 7 (not shown), when the effect of impedance shunting the series feedback may be compensated in the shunt feedback impedance, the impedance compensated representing the undesired element or added to obtained a desired result such as impedance matching. Alternatively bridge and shunt feedback paths may be used, Fig. 10 (not shown), or bridge and series feedback paths, Fig. 11 (not shown).

Fig. 1 shows the two end portions D of a disconnected runway track of I-section connected by a higher runway A, from which depends a cradle B having an I- section member C on which the trollies can be locked for transportation across the gap or obstruction. The cradle is formed at each end with a pointed nose c<2> having an antifriction wheel S adapted to engage inclined guideways G, whereby the member C is brought into alinement with either of the tracks D, the pivoted catches L<1>, L<2> locking the cradle in these positions.
