A strip 13 is wound around a mandrel 4 of elliptical crosssection Fig.2, (not shown) and simultaneously shaped by four rollers (9), one only being shown. Each roller is carried by a ring 1 and is adjustably urged radially inwards by a spring 7. On a common head 6 with the roller 9 is a further roller 10 which urges the helical band axially along the mandrel and may be of conical form to shape the strip. After the formed helix is cut to provide separate rings each ring is formed with locks at its ends at 920-940‹C. and cooled in oil at 230-250‹C. The band is produced by rolling melted cast iron of composition 3À0-3À3% C. 1À40-1À75% Si, 0À4-0À7% Mu, less than 1À2% K and less than 0À1% S, to a thickness of 1À5 mm. and width of 1400 mm The band is coiled and heated to 950-980‹C. for 6 hours, and then cooled over 13 hours to 680‹C. to produce spheroidal or flake-like graphite. After cold rolling with a 20% reduction, and cutting the band into strips, the strips are formed into helices at 630-650‹C. with the apparatus shown.

Abstract: 1,197,379. Transformers. E. SCHEUBECK. 9 Sept., 1968 [12 Sept., 1967, No. 42810/68. Heading H1T. An on-load tap changer comprises two parallel circuits each individually capable of connecting the load-line or neutral points "A" to tap connections 1-8 through tap selector contacts 14, 15 which contact the same tapping connections 1-8 in succession. The first circuit consists of a vacuum switch 11, and the second consists of two parallel paths, one having a main switch 12 and the other having an auxiliary swith 13 and a resistance R in series. Normally, the vacuum switch 11 and the main switch 12 are both closed, with the switch 13 open. When a change of tap position is initiated, switch 12 opens diverting the entire current to the vacuum switch 11 soon after which the contact arm 15 moves over to the desired new tapping position when switch 13 closes causing an inter tap circulating current to flow. This is followed by switch 11 opening and 12 closing in sequence. Contact arm 14 now moves over to the new position to coincide with arm 15, when switch 13 opens. This is followed by switch 11 closing to establish the initial condition when the total load current is shared by switches. 11 and 12.

Title: Coaxial cable
IPC: H01B11/18
Filed: 1965-10-11
Abstract: 1,094,599. Coaxial cable. UNITED-CARR Inc. Oct. 11, 1965 [March 2, 1965], No. 43111/65. Addition to 1,077,425. Heading H1A. The parent case claimed a coaxial cable in which the outer surface of an insulating sheath of synthetic plastics surrounding the central core was provided with spaced annular grooves, a coating of electrically conducting material being bonded to the whole grooved outer surface. The present improvement consists in making the adhesive strength of the bond equal to the cohesive strength of the material of the sheath to prevent relative movement between the coating and the sheath. The bonding may be done by making the outer surface of the sheath hydrophilic, sensitizing it so that it is readily oxidizable, catalizing it and depositing a coating of metal thereon.

Abstract: 1477597 Electrostatic precipitation installation AL EFREMIDI and AL SARALIDZE 23 Oct 1975 43627/75 Heading H2H Electrostatic precipitation apparatus comprises at least two precipitators 6, 7 having corona and receiving electrodes 8, 10 and 9, 11 respectively, the corona electrodes 8, 9 being connected to the high voltage winding 2 of a transformer 1, the primary winding 14 of which is supplied from an A.C. supply by way of a switch 16 and an inductor 15, the winding 2 further having a pair of opposing diodes 3, 4 connected thereacross the common point of which diodes is connected to the receiving electrodes 10, 11 and to earth, the arrangement being such that each precipitator, together with the high voltage winding, forms a discharge path for the other precipitator. Inductors 12, 13 may be connected between the winding 2 and the electrodes 8, 9 if desired. In operation, the switch 16, which may be a thyristor, is closed at the beginning of a half-cycle of the A.C. supply whereupon the electrode gap 6 charges by way of the diode 3 until the maximum voltage of the half-cycle. Diode 3 then cuts-off and the change in the gap 6 discharges into the electrode gap 7. During the next half-cycle of the supply the gap 7 charges by way of the diode 4 until the diode 4 cuts off when the gap 7 discharges into the gap 6 and the process repeats. Dust which collects on the receiving electrodes is discharged therefrom in the periods when the voltage across the electrode gaps is zero.

Title: Improved double depositing means for the imbricated depositing of sections severed from a material web

Abstract: 1,010,733. Sheet-delivery apparatus. A. WINDMOLLER & M. GENRICH, [trading as WINDMOLLER & HOLSCHER]. Nov. 19, 1962 [Nov. 22, 1961], No. 43653/62. Heading B6H. In apparatus wherein flat articles 3, e.g. sections of flexible tubing issuing from an extrusion machine and severed into lengths by cutters 2, can be diverted by a deflector 8 alternately or in batches either to forwarding belts 10 depositing the articles in overlapping formation on a belt 12 or to belts 9 similarly depositing the articles on belts 11, the dedositing belts 11, 12 are driven from one motor, and the belts 9, 10 are driven either from another motor 14 through a one-way clutch or from the main machine also through a one-way or overrunning clutch; which drive actuates the belts 9, 10 depends on the speed of the articles leaving the machine, i.e. the speed of the machine. Faulty delivery of the articles from the belts 9, 10 to the belts 11, 12, which might occur if the belts 9, 10 were driven from the machine and moving slowly during starting or slow running of the machine, is thus prevented. Articles leaving the cutters 2 are speeded up by rollers 4, 5, 6, 7 forming part of the machine. The shaft 16 of the roller 6 is coupled by an over-running clutch 20 to a pulley 22 over which passes belts 23, 24 driving the forwarding belts 9, 10. A motor 14 can also drive the pulley 22 through an over-running clutch 21, this drive being operative to move the belts 9, 10 at a sufficient speed for proper article delivery when the machine is running slowly, the clutch 20 then over-running because of the high speed of pulley 22 compared to the speed of shaft 16. If the speed of roll 6 is such as to cause over-running of the motor clutch 21, an automatic control cuts out the motor; the control automatically switches on the motor if the speed of the roller 6 drops. In a modification, Figs. 3, 4 (not shown), the shaft 16 of roller 6 drives, through an over-running clutch, a pulley over which pass belts driving another pulley over which passes the drive belts for the forwarding belts 10, 11. This second pulley is mounted by means of an over-running clutch on a shaft driven by a belt from a second motor. As in the first embodiment, the drive of conveyers 9, 10 is effected from the motor, when the roller 6 is running slowly.
