Abstract: 1,130,070. Induction heating. COMMISSARIAT A L'ENERGIE ATOMIQUE. 29 March, 1967 [5 April, 1966], No. 14243/67. Heading H5H. [Also in Division B1] A radio frequency induction furnace for melting refractory materials, e.g. UO 2 , Al 2 O 3 , MgO, zirconia, introduced in powder form and subsequently resolidified has the water-cooled copper inductor coil 1 separated from the charge 3 by a protective sheath 2 transparent to the radio-frequency radiation of coil 1 and comprising water cooled copper casings 5 separated by quartz or alumina strips 6 or sprayed with alumina. The casings 5 are mounted on a water-cooled ceramic base 11, and bound with glass or alumina fabric (see chain dots) or provided with top and bottom manifolds. Initially, to start the fusion, coil 1 is in the bottom position with respect to sheath 2 and a thin layer of the powdered charge is placed on the base 11 and preheated. If the fusion is performed in air thin plates of the metal whose oxide constitutes charge 3 are placed on the layer and the metal oxidizes and heats to start fusion. If the fusion is performed in a protective atmosphere, e.g. reducing, O 2 , an impervious quartz casing 16 has tubes for establishing this atmosphere and a tungsten filament is placed on the layer. Preheating can alternatively be carried out by a plasma or auxiliary arc torch. The layer melts except for an annular zone (12, Fig. 2) adjacent the sheath, which remains in the powdered or sintered state. Sheath 2 is then fed progressively with charge 3 and coil 1 is moved progressively in direction 4, the melted zone behind coil 1 re-solidifying, zone adjacent coil 1 melting, and zone above coil 1 remaining in powdered form, the liquid-solid fronts moving with coil 1. Casings 5 may have a profiled crosssection and sheath 2 may have a square- or star-shaped cross-section to produce refractory rods of similar shape.

Filed: 1959-04-27
Abstract: 874,719. Knitting-machines. PLANCK, A., [trading as FOUQUET-WERK, FRANZ & PLANCK]. April 27, 1959 [April 26, 1958; June 13, 1958], No. 14346/59. Class 74 (2). Patterning is achieved on the dial needles of a multifeeder cylinder-and-dial machine by withdrawing the normal clearing cams 37 to tuck height and by projecting at each feeder one or more auxiliary clearing cams 47 to selec. tively engage the butts 31 of needle slides 29 positively connected to the needles so as to advance selected needles to clearing position, Figs. 11 and 12. The slides 29 are accommodated in the dial needle tricks and have frangible tooth butts 31 which are broken off in a predetermined order as required for patterning. The auxiliary clearing cams 47 are pivotally mounted and a bank of them is provided at each clearing position. A corresponding number of rings 41 is provided within the dial cam cap and each ring is provided with a series of projections 46 corresponding to the number of banks of auxiliary clearing cams 47. The cams 47 are so formed at their inner edges that movement of the corresponding rings 41 causes the cams 47 to pivot and the outer camming edge of the cams either to be projected to engage the butts 31 of the slides 29 or to be withdrawn where the cams are inoperative. Movement of the rings 41 is effected by the provision of a bank of angular members 53 each engaging with a projection 55 in a slot 56 in a corresponding ring 41. The bank of members 53 extends through a slot in the cam cap and the outer edge of each member is provided with two protuberances 59, 60, between which the end of one arm 67 of a three-armed lever 61 projects. The levers 61 are pivoted at 62 and are resiliently urged by a spring 65 extending from a second arm 64 into a position in which the end of the arm 67 is midway between the protuberances 59, 60. A cable 79 connected to patterning mechanism is provided for each lever and when operated pivots the lever such that the arm 67 moves towards the protuberance 59. A lever 70 having a wedge-shaped end 69 is continuously oscillated by a cam 74 on the drive gear of the machine and engages behind the end of the third arm 68 of any selected lever 71 and moves it still further thereby causing the arm 67 to engage the protuberance 59 and to move the corresponding member 53 and ring 41 to positions in which the associated cams 47 are projected. When released the levers 61 return to their initial position where the arm 67 is now near to the protuberance 60. The continuous motion of lever 70 causes the wedge-shaped end 69 to engage in front of arm 68 of each lever 61 and pivots the levers 61 to cause them to move the members 53 and ring 41 which are in their operative position to their inoperative and initial position whereby the cams 47 are withdrawn. The cam cap may be assembled in segments to facilitate maintenance.

Abstract: 1384521 Centrifugal separator WESTFALIA SEPARATOR AG 27 March 1973 [27 April 1972] 14548/73 Heading B2P In a liquid centrifuge clarifier drum 2, 4 having a main sleeve valve 1 for controlling discharge of separated solids and an annular paring chamber 11 provided with a paring disc 12 for the discharge of clarified liquid under. pressure and with an annular cover 6, an  auxiliary sleeve valve 3 is provided for opening and closing off discharge orifices 13, 14 for the liquid portion of .the contents remaining in the drum after a centrifuging cycle, the valve 3 being provided on one side with a number of circumferentially disposed compression springs 15 and at its other side with a control chamber 17 which communicates with one or more passages 18 with a central annular groove 19 separated from the paring chamber 11 by a weir 20 the internal diameter of which is larger than that of the paring chamber cover 6. The operation of the centrifuge is controlled by a timed programmed switching system. During a centrifuging cycle a valve 22 in a pipe 21 for liquid to be clarified and a valve 24 in a pipe 23 for clarified liquid are open and the sleeve valves 1, 3 are closed. After a predetermined set time during which the separated solids have filled the chamber located outside a set of plates 9 in the drum, the switching system closes the valves 22, 24. Liquid still contained in feed pipe 21 flows out and causes the free liquid level 25 in the paring chamber 11 to move radially inwards and, because of the larger internal diameter of the weir 20 compared with that of the cover 6, liquid flows into the groove 19 and thence through passage(s) 18 into the control chambers 17. When the opening force exerted by the liquid in the chamber 17 exceeds the closing force of the springs 16, the valve 3 opens the passages 13, 14 for the discharge of the liquid portion of the contents of the drum into a collector 26. When the liquid level in the set of plates 9 recedes again and the closing force of the springs 15 predominates the valve 3 closes. After the elapse of the delay set by the programmed switching mechanism, the main sleeve valve 1 opens for discharge of the separated solids through passages 27 in a collector 28. With closing of valve 1 and opening of valves 22, 24 the next centrifuging cycle commences. In a modification, the valve 24 may be closed earlier than the valve 22.
