Title: Trailing gauge for measuring the profile of the burden in shaft furnaces
IPC: G01B21/20
Filed: 1972-11-27
Abstract: 1365256 Indicators for shaft furnaces DES ANCIENS ETABS PAUL WURTH SA 27 Nov 1972 [13 Jan 1972] 54665/72 Heading F4B [Also in Division G1] The profile of the upper surface of material in a blast furnace is determined by articulated arms 4 and 6, Fig. 1, inserted through the furnace wall. The lower end of arm 4 contacts the material surface 1, and the angle between arms 4 and 6 is measured electrically, as the distance arm 6 is inserted into the furnace. By combining the measurements as arm 6 is withdrawn the profile may be determined. The arms are shown in horizontal section in Fig. 4, rotation of arm 4 driving a gear 26 to operate Selsyn 12. The arm 6 is driven in and out by motor 27, another Selsyn 28 responding to this motion. The Selsyn cable 52 passes along housing 13 to a drum 15, and thence to drum 31 for connection to a Selsyn receiving device and pen recorder. This cable arrangement allows the housing to be isolated from the external atmosphere; cooling gas and lubricants may be blown into the housing at 16 (Fig. 3, not shown), and accumulated dust may be tapped off. A further cable 53 and a hose 54 may be provided for connection to a temperature sensor and a gas inlet on arm 4. The furnace gas temperature may thus be found as the profile is determined, and gas can also be extracted for analysis, e.g. of CO 2  content. The Selsyn 12 may be replaced by a rotary potentiometer. The furnace may be provided with several points spaced vertically or around its perimeter where the arms may be inserted. The measurements taken may be used to control subsequent furnace charging.

Abstract: 1413154 Pulse generators COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 27 Nov 1972 [26 Nov 1971] 54719/72 Heading H3T A variable frequency pulse generator comprises a two-transistor bi-stable circuit triggered at each side by a respective circuit comprising a variable time constant circuit associated with a uni-junction transistor. As shown in Fig. 3 when transistor T1 of the bi-stable circuit T1, T2 is non-conducting a capacitor C1 charges up through a resistor R.E. 1 and at the peak point of a uni-junction transistor UJ1 discharges into the bi-stable circuit to change its state. The potential at the collector of T2 rises allowing the capacitor C2 to charge through resistor R2 and produce a pulse to restore the circuit and allow capacitor C1 to recharge. The resistors of the timing circuit may be adjusted together or differentially to control the frequency and mark-space ratio of the pulses.

In a rotary sliding vane pump (or motor), as shown of the multi-abutment type, to reduce wear and friction between the end faces of the rotor 52, Fig.1, and the adjacent end-face48 of a housing and cover 20 and end-face 50 of a wear plate 18 the axial length of the rotor 52 is slightly less than the axial width of cam ring 14 to permit slight axial floating movement of the rotor. Annular grooves or pressure pockets 98, 100 provided in the end-faces 48, 50 respectively communicate through substantially constant area restricted passageways with the high-pressure side of the pumps (or motor) and through variable area restricted passageways with the low-pressure side of the pump (or motor). Pressure fluid is admitted to the pocket 98 from high-pressure passage 30 via ducts 90, Fig. 4 (not shown) annular groove 86 and V-shaped grooves 106, 108 and to the pocket 100 from the annular groove 86 via undervane pressure chambers 84, annular groove 88 and V-shaped grooves 110, 112, Fig.3. Pressure fluid seeps from the pockets 98, 100 past lands 102, 104 in the end-faces 48, 50 respectively. The land 102 seperating the pocket 98 from a recess 94 at the shaft end and the land 104 separating the pocket 100 from the shaft bore which is connected to low-pressure via a duct 97. On a build up of pressure between one of the lands and the associated end-face of the rotor, the rotor moves towards the other land until the clearances on the two sides of rotor are equal and the rotor is in pressure balance. The clearances are such to produce liquid films between the rotor and the end-faces to provide lubrication.

In a forced-flow steam generator having a separator 8 between the evaporation and superheater stages 7, 8, the discharge liquid from the separator 8 either passes through a heat exchanger 16 in the feed pipe 18 to the evaporator or discharges into the pipe 18 and a temperature responsive device 25 in the feed pipe 18 actuates a control unit 27 upon change of temperature to produce a transient signal which operates a valve 15 in the discharge pipe 17, or a feed control valve, to produce a temperary connection and prevent oscillations in the steam supply. In Fig. 1 rise in temperature in the pipe 18 operates valve 15 to cause a temporary reduction in the discharge flow, whereas in Fig. 2 (not shown), wherein the pipe 17 discharges into the pipe 18, rise in temperature in the pipe 18 operates a fuel valve (32) to cause a temporary increase in the fuel supply. A feedwater control valve 3 is controlled by a steam flow responsive device 20 and a device 21 responsive to the level of water in separator 8 whilst the fuel control valve 32 is controlled by a steam pressure responsive device 31.

Abstract: 726,576. Variable capacitors. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL., HONORE, E. A. H., TORCHEUX, E. L. G., and ROY, G. C. March 13, 1953 [March 14, 1952], No. 7025/53. Class 37. In a variable capacitor of the type in which two coaxial cylindrical sleeves are fitted one within the other so as to permit of their relative movement, the sleeves, of which at least one is slotted along its length, are of ceramic material and the electrodes consist of conductive coatings on the outer surface of the outer sleeve, and the inner surface of the inner sleeve, respectively. The relative movement between the sleeves, which serves to vary the capacity, may be rotational or axial. As shown, two electrodes (2, 3) are provided on the inner sleeve and two (6, 7) on the outer, these forming two capacitors which are variable simultaneously by either rotational or axial movement of one sleeve with respect to the other. The slot 5, which may be in either of the sleeves, is provided to allow the slotted sleeve to be deformed in assembling one sleeve within the other. Providing the ceramic material is sufficiently resilient, this deformation will ensure close contact between the sleeves; but if it is .not, auxiliary means are employed for this purpose. Thus, if the slotted sleeve is the inner one, the slot may be filled by a plug of resilient material; whereas if the slotted sleeve is the outer one, a clamping ring is used, as in the embodiment of Figs. 9 to 11 (not shown). The ceramic material may be steatite. The electrodes may be so shaped as to cause the capacity to vary in any desired way as a function of the relative movement between the sleeves.
