Title: Improvements in or relating to indirectly heated thermionic cathodes
IPC: H01J1/22
Filed: 1936-04-08
Abstract: 476,675. Direct connections between conductors. RADIOAKT. - GES. D. S. LOEWE. April 8, 1936, No. 10335. Convention date, April 10, 1935. Drawings to Specification. [Class 38 (i)] [Also in Groups XL and XI] Thin tungsten or molybdenum heating filaments for indirectly heated thermionic cathodes become brittle when in contact with glowing metals of the iron group, particularly nickel, probably due to formation of an alloy. This may be prevented by making the holding wires of tungsten or molybdenum and connecting them by welding, or by an auxiliary binding wire of the same metals. Alternatively if the holding wires are of metals of the iron group, welding is replaced by clamping, and the clamping point is kept at a temperature below glowing, either by winding the heating coil at the end nearest the holding wire with a larger pitch or by embedding the clamping point in a ceramic substance. The Specification as open to inspection under Sect. 91 includes also a reference to chromium as a metal forming undesirable alloys. The end of the heater may be secured by a tubular nickel clamp surrounding the end of an insulator carrying the heater. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,075,684. Deforming coil ends. G. A. REDDYNGTON. March 12, 1965, No. 10563/65. Heading B3E. Apparatus for forming a loop on a coil spring comprising a supporting member having a spring receiving and locating bore therein, loopforming mechanism adjacent said bore operative to engage and bend an end portion of a spring located in the bore is characterized by the provision of means for directing into said bore a jet of air having therein an axial and an angular component of motion to thereby both advance and rotate a spring therein to move the spring and orient it with respect to the loop-forming mechanism. A spring 14 is rotated and fed axially in a tube 13, carried by a carrier wheel 11 intermittently rotated by ratchet means, by a helical jet from a nozzle 27, or from an oblique passage in the wall of tube 13, to a forming anvil 16. A slightly inclined member 29 is then moved down to bend the end loop of the spring over the anvil 16. The carrier wheel 11 is then rotated one step to carry the spring to a station where the other end loop is bent over by similar means at that station, a second helical jet of air moving the spring to the other end of the tube 13. The spring with both end loops bent may be ejected by an air jet at a third station. One end loop may be made larger than the other by suitably adjusting a pick 31 in the member 29. In another embodiment, Figs. 9, 10 (not shown), the spring is carried by a tube in an arm pivoted to move from one position where one end loop of the spring is bent to another position where the other end loop is bent, at this latter position the forming anvil is moved from the tube end after deforming of the end loop so that the spring may be ejected from the tube. Two pivoted arms each carrying a tube to support a spring are provided so that the second end loop of the first spring is bent at the same time as the first loop of the second spring. In a fiuther embodiment, Fig. 11 (not shown), both end loops of the spring may be bent while the spring is in the same fixed tube, helical air jets blowing the spring from one end to the other of the tube, the anvils at both ends being retractable, and an annular groove in the tube bore accommodating an already bent end loop to allow the spring to be positioned by rotation for the bending of the other end loop.

Abstract: 497,480. Metal - heating &c. furnaces. MACDONALD, J., and G.W.B. ELECTRIC FURNACES, Ltd. April 15, 1937, Nos. 10784 and 34748. [Class 51 (ii)] A furnace installation comprises sets of furnace bases for use with a single belltype furnace unit and an appropriate number of bell covers for charges to be preheated and cooled, each base having pipe connections with at least one other base in its set for circulating a heat transferring gas between the bases, the cycle of operations being such that the bases arc charged in succession, and each charge is first preheated by heat interchange with a cooling charge, then heated by the furnace unit, and finally cooled by heat interchange with a charge to be preheated. In the four unit plant shown in Fig. 1, the bases 1, 2, 3, 4, which are charged in that order, are connected in pairs 1, 3 and 2, 4 by pipe systems 10, 11 leading to the suction and delivery ports of the fans 51. At the stage shown the charge 16 on the base 1 is being heated by the furnace unit 5, while heat interchange is being effected between a cooling charge 17 on the base 4 and a charge 19 being preheated on the base 2. The base 3 carries a charge which, after cooling off naturally, is to be replaced by a new charge. The charges 16, 17 and 19 are enclosed within protective covers 6, and around the cover on the base 2 is a heat-insulating bell 15. The fans 51 are preferably mounted so that they can be moved axially from a lower position shown at the bases 2, 4, Fig. 1, and on Fig. 5, in which their delivery ports register with passages 56 connected up with the pipe systems 10, 11, to an upper position, shown at the base 1, where the fan is effective to circulate the atmosphere within the cover 6. A spigot portion 52 on the fan closes the passages 59 for the internal circulation of the atmosphere when the fan is in its lower position. The change over from the lower to the upper position and vice versa may be effected automatically by the positioning and removal of the heating-bell. In a modified arrangement, Fig. 6 (not shown), the first and third and the second and fourth of a line of four bases are connected, so that charging can proceed in sequence along the line, and in a further modification, Fig. 7 (not shown), an indirect heat exchange between the atmospheres around two charges is effected by passing one atmosphere through a coil around which the other is circulated. When six bases are connected up in two sets of three the preheating and cooling of each of the charges can be effected in two stages.
