Title: Coordinating the travel of a pusher ram in a coke oven with the travel of a coke quenching car
IPC: C10B41/04
Filed: 1974-07-22
Abstract: 1478637 Automatic control KOPPERS CO Inc 22 July 1974 [20 July 1973] 32410/74 Heading G3N A correspondence control system is arranged for co-ordinating the travel of a pusher ram in a coke oven with the travel of a coke quenching car propelled by a locomotive, and relative to the oven, the car receiving hot coke from the oven. A pulse generator PUI, Fig. 1, on the pusher ram machine emits a pulse for every pre-selected incremental distance travelled by the ram from the oven face at the start of the push to the completion thereof. A transmitter on the machine sends these pulses via collector rails to a receiver on a locomotive for propelling the quench car. The pulses are applied to a stepping motor STP which drives an indicator showing the ram position. When the ram has moved into the oven far enough to deposit enough coke in the end of the quench car, the quench car loco will be started. A pulse generator PU2 on the quench car begins to produce pulses which are applied to a step-motor STQ driving an indicator showing the quench car position. The quenching car locomotive operator can therefore compare the indications of the two indicators and determine the position of the quench car relative to the ram position at any moment during the push and in relation to the amount of coke in the oven. When the ram has travelled its full stroke, a limit switch LS1-2 is opened thereby stopping the pulse generator PU1 and the transmitter, and actuating a visual and aural alarm, whereupon the ram operator withdraws the ram and the quench car operator manually controls the locomotive to move the quench car to the quenching station. A reset relay RS causes the motors to return the indicators to their start positions ready for a new push. Alternatively the quench car speed may be automatically controlled to co-ordinate with the rate at which the coke is being pushed by the ram, as described with reference to Fig. 2 (not shown). In this arrangement a further stepping motor (STQF) is energized by a signal which is a function of the difference in pulse repetition rates of the ram and quenching car pulse generators. The stepping motor (STQF) accordingly operates rotary cam limit switches to adjust the speed of the quenching car whereby to correctly position the car relative to the ram.

Abstract: 900,017. Electric indicating systems. SANGAMO WESTON Ltd. Oct. 17, 1958 [Oct. 22, 1957], No. 33236/58. Class 40 (1). A suppressed zero tachometer comprises a generator driven by a shaft whose speed is to be determined and supplying two output voltages, one of which is fed through a rectifier circuit to produce a constant D.C. voltage above a predetermined shaft speed, which is used to oppose the rectified value of the other output voltage. As shown, a tachogenerator 10 has two output windings 11, 12, each generating a voltage whose amplitude and frequency is proportional to the speed of rotation. The output of winding 11 is fed through a saturable core transformer 14 and a full-wave rectifier 18 to a differential bridge network 19. The output of winding 12 is fed through full-wave rectifier 26 to bridge 29 comprising three resistors 31, 32, 33 and a Zener diode 34, and the output of bridge 29 is also fed to differential bridge 19, whereby any difference in D.C. voltages from bridges 18 and 29 is indicated by meter 24. At low speeds the rectified D.C. voltage from bridge 26 is below the Zener voltage of diode 34, and the inputs to bridge 19 from its two sources are approximately equal, and meter 24 reads zero or a minus quantity, but when the speed is increased such that the voltage across diode 34 exceeds the Zener voltage the output from bridge 29 remains at a constant value, and meter 24 gives an increasing deflection with increasing speed. The capacitor 27 helps to maintain the output voltage of bridge 26 at above the Zener voltage of the diode. Adjustment of the scale readings is effected by altering resistors 17 and/or 28.

Patent GB-335292-A (GB)
IPC: C08G63/48
Abstract: 335,292. Imperial Chemical Industries, Ltd., Baird, W., and Walker, E. E. July 3, 1929. Ester condensation products.-Non-hydroxylated fatty oils, such as olive, tung, and linseed oils, are incorporated with resins of the polyhydricalcohol-polybasic-acid type by the use of a hydroxylated oil, such as castor oil, as a vehicle. The resin ingredients and the hydroxylated oil are heated until a homogeneous mass is obtained to which the non-hydroxylated oil is added gradually. In an example, 31 parts of glycerol, 74 of phthalic anhydride and 75 of castor oil are heated to 210 -220 C. and stirred until clear; 50 parts of tung oil are then added, 10 parts at a time, until the whole is incorporated, when the temperature is raised to 240 C. until the mixture begins to gel. In a second example, 20 parts of glycol, 21 of glycerol, 99 of phthalic anhydride, and 48 of castor oil are heated under reflux at 185-195 C. until clear; 40 parts of linseed oil are then added in portions of 5 parts each. When the whole is added the mixture is kept at 185-195 C. for 3 hours; the condenser is then removed and the temperature is raised to 220-230 C. for 6 hours. Specification 235,595 is referred to.

Filed: 1945-12-14
Abstract: 605,734. Non-contact-making relays. YATES, J. G., ROBBINS, R. C., and HVINDEN, T. P. Dec. 14, 1945, No. 33976. [Class 40 (iv)] [Also in Groups XXXVI and XL (c)] An H.F. milliwattmeter comprises a D.C. or L.F. bridge circuit one arm of which includes two series connected frequency independent non - linear resistance elements which are arranged to be fed in parallel with H.F. energy by means of a coaxial line. In the D.C. bridge shown the said elements are negative-temperature coefficient bead thermistors T1, T2 included in a self-contained coaxial unit, Fig. 5, designed for plugging in to the end of the H.F. line. An optimum value R of D.C. working resistance (T1, T2 in series) at bridge balance is chosen such that the equivalent resistance for T1, T2 in parallel, Fig. 1 (not shown) matches the line sufficiently accurately for the range of measurement. In the bridge arm comprising R1, R4 the value R1 is approximately equal to R (T1, T2 in series) of the adjacent arm R, R5 so that the D.C. power change in R may be evaluated from the change in D.C. voltage across R, R1 as disclosed in Specification 588,903, [Group XXXVI]. The coaxial unit of Figure 5 also includes disc thermistors D1, D2 which act automatically to prevent zero drift. of the bridge microammeter G at different ambient temperatures. In calibrating the bridge the switch S is at position 2 and VR3 is adjusted to the middle of its range, VR4 is varied to effect bridge balance and the D.C. voltage across RR1 then measured ; H.F. power is then applied to R by plugging in to the end of the line the unit of Fig. 5, for example, the magnitude of this H.F. may be such that meter G reads 80 divisions. The bridge is then re-balanced by VR3 and the voltage across RR again measured; the D.C. power change in R then evaluated is equal to the applied H.F. power. The reading of 80 divisions is restored by VR3 and a calibrating resistance VR2 in series with meter G is adjusted so that the latter reads directly the power as calculated. Bridge sensitivity is stated to be appreciably constant with the ohmic values given and the bridge fed with 12 volts. With the switch in position 1 the meter G may be calibrated for use as a voltmeter by inclusion of resistance R7. In the coaxial unit as shown, Fig. 5, T1, T2 are disposed between two plates 1, 2 capacitatively coupled on opposite sides of a brass block 3 bored to receive a coaxial socket 4 the inner conductor of which terminates at the junction of T1, T2 and the outer of which is extended by the brass block 3. The disc thermistors D1, D2 are clamped by an insulating plate 7 over the end of the block 3. Specification 604,496, [Group XXXVI], also is referred to.

A majority decision is not therefore carried out and the shift register need not be larger than the word. Errors are not detected in the individual ones of the remaining channels but only as a group but it is assumed that only one bit will be erroneous hence the preceding bit is substituted. The example described in the Specification has four bit code words, two bits indicating the direction and the remaining bits the position of a transition.
