An interdigitated delay line suitable for use in a travelling wave tube or magnetron comprises a number of metal fingers of length h spaced a short distance w from a U-shaped metal back plate, i.e., w/h is small, the fingers extending within the U perpendicular to the sides and parallel to the base and the fingers are secured to the metal back plate by metal connections spaced alternately by x and h-x from one end of the fingers, where OLxL<SP>h</SP>/ 2 . The connections may be short metal rods or rectangular blocks extending the whole distance x as shown in Figs. 1, 11 respectively where a<SP>1</SP> ... a<SP>5</SP> are the fingers, b<SP>1</SP> ... b<SP>5</SP> the connections and 20 the back plate which is provided with shoulders 21, 22. Two, four or more interdigital lines may be connected in parallel, the resulting structure being shown in Figs. 14 ; 21, 22 for two lines in parallel. The invention may also be applied to forward wave travelling wave tubes, backward wave oscillators, Fig. 25 (not shown) with or without crossed fields or to magnetrons, Fig. 23, and the design of the line structures is discussed theoretically. The positions of the connections are preferably such that x=h/3 and h-x= <SP>2</SP>h/3, the length h of the fingers can be as much as ho =#/4- K where K = no of lines in parallel compared with #/4 for prior art structures, and the beam width is equal to h. The parameters dx =, D=h-x and S = cross-section of fingers are chosen to get the desired dispersion curves for spatial harmonic operation. In Fig. 11 the supports b<SP>1</SP> ... b<SP>5</SP> may be narrower than or the same width as the fingers in the direction of electron flow. In Fig. 14 operation is similar to Fig. 1 provided that points al, c<SP>1</SP> ; a<SP>2</SP>, c<SP>2</SP>; are brazed or welded together or a<SP>1</SP>, c<SP>1</SP>, a<SP>2</SP> c<SP>2</SP> /h   h &c. are small.

Filed: 1920-06-10
Abstract: 160,700. Brigham, N. E. June 10, 1920. Centrifugal machines; moulding confectionery. -In the manufacture of confections of the chocolate cream type, i.e. confections having a centre or core of one material surrounded by a shell or casing of another material, a substantially paraboloidal shell is first formed by the action of centrifugal force on the molten material introduced into a rotary mould the rotation of which is nearly or completely stopped, when the shell is set, to allow the core to be introduced in a plastic condition, the casing being completed by adding material on to the core and allowing it to cool and unite with the paraboloidal shell. The rotary mould is divided into sections, transversely or axially, to facilitate removal of the finished confection. One form of mould, shown in section in Fig. 1, is rotated by gear-wheels and comprises sections 8 and 9 mounted in the bowl 1, the lower portion 12 of which is recessed to complete the parabolic contour of the mould. The upper mould section 9 is secured to the bowl 1 by a thumbscrew 10 and a spring clip 11, and is formed with a funnel-shaped opening for the introduction of molten materials. The bowl is provided with cooling fins 26. Fig. 5 shows a section of a completed confection showing the junction 17 between the covering material 16 and the paraboloidal shell 14, removal being effected by removing the mould sections 8 and 9 from the bowl 1. Fig. 8 shows an axially divided mould, the four sections 30 being hinged to a common member 34 mounted on the driving-shaft 36, which has a conical extension 37 engaging with a similarly shaped recess in the mould sections. A cap 40, having a funnel-shaped opening, combines the mould sections and is assisted by a spring 41 which operates when the cap 40 is removed and the mould is split by forcing it down on the conical extension 37. In a further modification, Fig. 11, the shell is formed with a cylindrical extension 14 which is remelted to form the covering; after the core has been introduced, by electric resistances coiled around the upper mould section 9. The mould may be provided with a suitable pattern or may be lined with paper to enclose the completed confection when removed from the mould. The molten material for forming the shell may also be introduced into the mould by a pump secured to the bottom of the bowl 1.
