Title: Steelmaking electrodes
IPC: H05B7/14
Filed: 1975-09-15
Abstract: 1512038 Nipple-joints for carbon arc-electrodes BRITISH STEEL CORP 15 Sept 1976 [15 Sept 1975] 37765/75 Heading H5H A carbon or graphite threaded nipple 3 for joining together adjacent carbon or graphite electrode sections 1, 2 is reinforced by at least one axially extending metal rod 8. The rod 8 is preferably in the form of a steel bolt which is tensioned by a nut 9 to pre-compress the nipple 3 so that the abutting faces of the electrode sections 1, 2 may be pressed together with a greater than conventional pressure without subjecting the nipple to excessive tensile stress. The nipple crosssection may therefore be reduced enabling the "collars" 6, 7 of the electrode sections to be made larger. The bolt is preferably made of ferritic steel so that below its Curie point, the skin effect of the alternating arc current increases the effective resistance of the bolt and prevents its overheating. As the electrode is consumed and the nipple is lowered towards the melt, the bolt may melt. Several bolts may be provided.

Filed: 1956-12-17
Abstract: 856,140. Automatic frequency control systems; thermionic valve gating circuits. MORLE, C. W. (Philco Corporation). Dec. 17, 1956, No. 38396/56. Classes 40(5) and 40(6). In an AFC circuit for pulsed frequencies control pulses each of amplitude representing any frequency error are derived from a discriminator and applied to a frequency correcting circuit with a delay preventing degenerative feedback on the control pulses and through a gate circuit whose output is connected with negative feedback to its input with a delay such that control changes are not counteracted but otherwise the AFC output is maintained constant. As shown, a radar system of Doppler type indicates moving targets by differentially combining the rectified outputs of two frequency selective I.F. amplifiers A, B whose outputs are zero at the nominal difference in frequency between a local oscillator and transmitted and received pulses but anti-symmetrical and opposite at either side of the frequency, as shown at d, e, to form a frequency discriminator the differential output being applied at 84 to an indicator. The I.F. amplifiers are normally connected only to the receiver mixer 61 for received pulses, but a gating pulse E commencing with the transmitted radar pulse blocks receiver mixer 61 and connects a normally blocked mixer 62 responsive to an attenuated value of the transmitted pulse to the I.F. amplifiers A, B. During pulse E a delay line 103 then passes the discriminator output to a clamping circuit N comprising three series connected valves 86, 87, 88 whose input is applied to the grid of valve 86 and whose output taken from the junction of valves 87, 88 is applied to that side of a storage or memory capacitor 85 connected to the frequency controlling reflector electrode of a klystron local oscillator so that a stabilized I.F. is produced at recurrent periods coinciding with the delayed pulses E, the clamping circuit being opened at the said delayed periods by pulses from the transmitter applied at F through a delay line to the damping circuit, self bias developing on capacitors 95, 96 otherwise closing the clamping circuit. Further, negative feedback from capacitor 85 through an adjustable D.C. amplifier 107 and delay line 108 may be arranged to ensure that the bias on the grid of valve 86 is stabilized at a constant value but to have no effect, due to the delay line 108, on changes in amplitude of the pulsed inputs. Adjustment in gain of D.C. amplifier 107 and AFC feedback D.C. amplifier 106 is initially made until the frequency of local oscillator 57 is correct.

To prevent jamming of the radial seal for the piston of a rotary-piston machine which is rotatably and eccentrically arranged within a cylinder whose contoured surface together with side walls defines an inner space, the radial seal which comprises a sealing strip having clearance within a groove extending the axial width of the piston and a sliding edge parallel to the piston axis for continuous sealing engagement with the contoured surface to seal two adjacent chambers from each other, has the sliding edge of the sealing strip tiltable about an axis parallel to the piston axis which is located in each position of the piston in front of the sliding edge as viewed in the direction of rotation of the piston. Applied to a trochoidal type rotary-piston engine, the sealing strip 6, Fig. 2, loosely mounted in a groove 5 in the corner 8 of a three-sided piston, on rotation of the piston swings through an angle Ï max with respect to the two-lobed epitrochoidal contour 1 .of the cylinder. The invention provides that the sliding edge 7 is tiltable about an axis lying within the arms of an angle a which is the supplement of the angle ° max. with the piston rotating in the direction of the arrow D. As shown in Fig. 3, a recess 10 is provided on the trailing side of the sealing strip 9 and the sliding edge 12 tilts about the base 11 of the recess.

Abstract: 1,110,186. Winding webs. JOHN DUSENBERY CO. Inc. 2 Sept., 1966 [3 Sept., 1965], No. 39338/66. Heading B6B. Adaptors 10, 30, for mounting a core 41 on a driven mandrel 37 so as to rotate the core with slip for winding a thin film web on the core, comprise an outer cylindrical member having a portion insertable into the core with means for preventing relative rotation between the outer member and the core, and an inner member insertable on the mandrel, bearing means, e.g. a ball bearing, being provided between the two members. As shown, the two adaptors are held between two nylon spacer rings 40 axially movable but not rotatable relatively to the mandrel 37. The outer member of the adaptor 10 comprises two parts 11, 18 of aluminium secured together by screws 21, the part 18 being reduced to fit into the core 41. Fitting into a circumferential groove in the part 18 is an inner rubber tubular ring 26 and an outer coiled spring 27, the latter extending beyond the outer surface of the part 18 so that it bites into the core 41 and prevents relative rotation between the core and part 18. A ball-bearing 13 is provided between the outer member 11, 18 and an inner member 25 of low friction material, the member 25 being rotatable about the mandrel 37 but is axially slidable thereon. A smooth metal plate 15 is fixed to the part 11 and abuts one of the spacers 40, the frictional engagement between the parts 15, 40 constituting the sole drive from the mandrel 37 to the core 41. The other adaptor 30 has inner and outer parts with an interposed ball bearing 13<SP>1</SP>, the outer part being grooved to receive a tubular rubber ring and a coiled spring 27<SP>1</SP> as in the case of part 18, for engaging the core. The inner part 35 is of low friction material and abuts against a spacer 40. A number of assemblies as described may be mounted on the mandrel 37 for winding narrow films leaving a web slitting machine, -the mandrel for this purpose having at one end a stop collar 38 and at the other end a thrust bearing 42 pressed axially by a forked lever 47 operated by a hydraulic cylinder 45. The web material is fed to the winding apparatus by a roller driven at constant speed, and the winding mandrel speed is such that the surface velocity of the core is somewhat greater than the linear speed of the web.
