' condenser system for thermionic tube high frequency transmitters.
Another object of our invention is to provide a compact and efiicient adjustable condenser system to be employed in electrically balanced circuit arrangements utilizing water cooled thermionic tubes.
Still another object of our invention is to provide a compact and efficient condenser system adapted to electrically balance an arrangement of thermionic tubes.
Other and further objectsof our invention reside in certain structural features we employ whereby the condenser system is shielded and occupies a relatively small amount of the available space in high frequency transmitters.
Our invention will be more'fully understood from the specification hereinafter following and by reference to the accompanying drawings, in which:
Figure 1 shows an end view in part section of ourinvention Fi 2 shows a top plan view of our invention; 1 s. 3 and 4 show a side elevation of the con enser system of our invention; and Fig. 5 is a schematic circuit diagram showing the operation'of the condenser system of our invention.
In high frequency transmitters it is necessary to employ some'value of capacity to control the frequency characteristics of the circuits. In high power transmitters, thermionic tubes having their anodes cooled by a circulatory liquid, occupy considerable space. It is desirable to confine the apparatus in as small space as is consistent with efiiciency. In the combined condenser system of our'invention the capacity necessary to control the frequency characteristics of the circuits and compensate or balance irre ularities in the thermionic tubes, is confine within a small area with an increase in efficiency and stability of the transmitter resulting.
In Fig. 1 of the accompanying drawings,
OF NEW YORK, N. Y., A CORPORATION OF oonnnnsnn sYs' rnu 1929. Serial No. 355,375.
an end view in part section shows a part of the combined condenser system of our invention. The comblned condenser system illustrated in the accompanying drawings is of the design to be associated with two thermionic tubes. However, a single one of the tubes may be used or a cascade system of balanced tubes may be employed where the transmitting system so requires.
In Fig. 1, a socket 1, or retainer for the tube 2, is indirectly supported by the ma n framework of the transmitter. Socket 1 is provided with a clamping member 1a. which looks and seals flange 2a of tube 2 against the fluid circulation compartment 16 of socket 1. Flange 2a is integral with the anode of thermionic tube 2. Compartment 1b of socket 1 may be a metallic cylinder of sufliciently large dimensions to permit the anode of tube 2 to be supplied with proper circulation of the cooling fluid. The lower section of compartment 1b is provided with fluid conducting members 19 and 20 adapted to admit the fluid to and from'container 1?). A cylinder 10, of metallic material, surrounds and is electrically connected to compartment 16 of socket 1. Cylinders 4 and 5, of suitable metallic material, are of slightly different diameters;
the inner wall of cylinder 4 bearing against the outer wall of cylinder 5. Cylinders 4 andv 5 are supported by arm 3 and are electrically insulated and spacially positioned from socket 1 and cylinder 10. Portions 15 are cut away from cylinder 10 to prevent voltage discharge to arm 3. Cylinders 4 and 5 have sections 7 cut away, which sections may be of any dimension or shape desired. Sections 7 may comprise the equivalent of one half the area of either cylinder. An annular recess or groove is provided in cylinder 5 wherein a= may be caused to coincide with each other or to depart from this agreement. The former position is that wherein the capacity between .Member 4 is adapted to -rotate. by means of.
In the latter position, where the efiective area.
is increased by closing theopenin 's 7, the capacity is of maximum value; ember 5, as heretofore ,stated,-issupported by arm 3.
, which turns through bearing 26. A shield 27 is provided around the gears to prevent sparking over to cylindrical plate member 10'and to socket 1. An eccentric bearing'may be provided for shaft 28 to permit adjustment effecting the proper engagement of gear 22 with the gear teeth out into the wall of cylinder 5. An annular shaped metallic member 14 is attached to socket 1 by angle 8. Annular shaped members 16 and 16a of suitable metallic material support and are electrically connected to cylindrical plate members 17, 17a and 17 b. Cylindrical plate members 18 and 18a are supported b and electrically connected to annular shaped member 14. Cylindrical plate members 18 and 18a are s acially positioned with respect to plate mcm ers 17, 17a and 17b. Controlling means serving to hold late member 176 in the proper position and or adjusting the capacitive relation between plate members 17-18 are illustrated in the figures to follow. Plate members 17, 17a, 17]), 18, 18a, 10 and the wall of socket .1 constitute a condenser, the capacity of which depends upon the effective capacity area of these members. 4
Fig. 2 1s adiagrannnatic plan view of the condenser system of our invention showing the mechanical arrangement for adjusting the position of plate members 4 and 4a. Ther- IIllOIllC tubes 2 and 2d having'their anodes cooled by a c rculating fluid are positioned in sockets 1 and 1d, respectively. Cylinders 4, 5 and 4a, 5a are concentric with therwater ackets of tube sockets 1 and 103 respectively. Cylinders l0 and 10d are likewise concentric with respect to sockets 1 and 1d. Cylinders 10 and 1003 are electrically connected to seekets 1 and 103, respectively, and constitute one slde of the balance condenser. Cylinders 4 and 4a are rotated simultaneously by means of crank 31 through insulated shaft members 29 and 29a. The shaft immediately assoclated with crank 31 cooperates with indicating mechanism consisting of bevel gears 32 and 33 and counter 34. Counter 34 is mounted so as to be visible through a window provided in panel 35. A knurled nut controls the engagement of worm gear 24a and part 31a. The latter provides means for readily effecting the relative positioning of members 4 and 4a in the necessary relatlon to counteract dissimilar characteristics ofthermionic tubes 1 and 1d.
Fig. 3 of the accompanying drawings shows aside view of the clutch mechanism for adjusting the relative positions of plate members 4 and 4a, shown in Figs. 1 and 2, previously referred to. The section ofcyhndrical plate member 1003 which, similar to plate 10, is cut away, is shown in greater detail. This cut away portion is to prevent voltage flash-over between cylindrical plate members 3 and 3a illustrated'in the other figures of the accompanying drawings.
In Fig. 2, guide rods are shown which run parallel with respect to the axes of cylinders 10, 10d, the upper ends of such rods extending through holes 50,51 of plate member 49. The upper end of an adjusting rod 47 rests in bearing 49a which is of insulating material. TlllS adjusting rod is mechanically as sociated with control rod 55, which in turn extends through panel 35 and is operably controlled b crank 31a.
The controlmechanism for adjusting the position of plate members 17, 17a and 171), shown in Fig. 1 is illustrated in Fig. 4 of the accompanying drawings. A duplicate arrangement of cylindrical plate members similar to members 17, 17 a and 176 are provided for thermionic tube socket 1d and controlled in like manner. The control mechanism consists of a threaded rod 47 engaging with a threaded bore 46 in plate 49. Plate '49 is connected to plates 17a and 17d which are adjustable in relation to cylinders 10 and 10d.
Bevel gears 53 are actuated by rod 47 and shaft Shaft 55 and rod 47 rest in bearing member 52. Bearing 52 is supported by a cross member of suitable insulating material which is carried by insulating member 13a. The lower adjacent sections of cylindrical late members 10' and 10d are cut away. late 49?; is attached to cylindrical plate members 17a and 17d and movable therewith. The hole through. plate 491) permits unrestricted vertical movement of plate 49 with respect to threaded rod 47. A bearing is provided in cross-member 49a for the upper end of rod 47. The control mechanism for plates 4 and 4a and the control mechanism for cylindrical plate members 17, 17a and 17b anti similar plate members for socket 103, may b controlled by common mechanical means whereby reduction gears or other means permit the proper relative movement of the plate members as determined by the frequency characteristics of the tubes, the associated circuits and capacity of the condenser units.
The condenser system of our invention is adapted to a variety of applications. Two individual condensers are provided immediately connected with each of the thermionic tubes. In the drawings two thermionic tubes are shown, however it is obvious that one tube,
or more than two tubes, may be employed.
Thermionic tubes .l and 211 may be associated with sockets 1 and 1d respectively and the 5 latter positioned exterior. to the condenser system. However, thearrangement shown utilizes a minimum of space and increases the cazfpacity in that the tube sockets increase the e ective area of the stationary plates.
Fig. 5 of the accompanying drawings shows schematically the operation of the condenser system of our'invention. Condensers 14 and 1d-4a represent the condensers The schematic circuit diagram illustrates one application of the condenser system of our invention wherein the frequency characteris- 9 tics of a balanced thermionic tube arrangement are controlledand whereby the circuits are neutralized'to prevent inter-oscillation of the tubes. The neutralizing or balancing condensers are represented by. plates 1-4 and .ld-4a respectively. The condensers for controlling the frequency characteristics of the oscillate or amplifying circuit are represented by p ates 1'0--17a and 10d-17d. It is obvious that the condenser system of our invention may be employed in many different circuit arr-an ements and it is therefore not intended to 'mit our invention by the schematic circuit diagram shown. a
We realize that many modifications of the condenser system of our invention are possible without defining from the spirit of our invention. number of cyhndrical late members simi ar to members 4, 5, hav-.
3 which are controlled, may nstlead of cylindrical plate mememing openi employed.
' bers, semi-cylindrical members may be ployed wherein one of the semi-cylindrical members may be adjusted to {live in capacity efiect that of acomplete cy 'nder. As to number of plates, inter-plate insulationand supportin means, many modifications are possible. t is to be clearly understood that the embodiments of our invention are not to be. limitedto the fore oing specificationf or to the accompanying wings but only as defined in the scope of the a ded claims.
