Title: Electrical waveguide arrangements
Inventor: LEWIN LEONARD
IPC: H01P1/02
Filed: 1961-03-30
Abstract: 905,774. Waveguide bends and junctions. STANDARD TELEPHONES & CABLES Ltd. March 30, 1961, No. 11765/61. Class 40 (8). Two inclined rectangular waveguides are joined by a junction including a reflecting surface and dielectric diaphragms on either side of the junction, the material and dimensions of the diaphragms being such that they reflect energy incident on them at a glancing angle. Fig. 1 shows an H-plane section of a junction between two rectangular waveguides 1, 2 utilizing the H 01  mode of propagation. The waveguide mode may be considered to be the resultant of ordinary plane waves travelling at the velocity of light at an angle # = #/2a to the axis 7 and suffering repeated reflection from the walls of the guide. Since the dielectric diaphragms 5, 6 do not disturb the direction of wave fronts incident at near normal angles (# is exaggerated in the Figure), wave fronts whose paths are shown at 8 and 11 in guide 1 result in wave fronts 8<SP>1</SP> and 11<SP>1</SP> in guide 2 and no change in the manner of propagation arises. However, if both the diaphragms were transparent to wave fronts such as those shown in guide 1 at 9 and 10, wave fronts indicated by broken lines would result in both guides with consequent perturbation of the normal mode. According to the invention, the dimensions and dielectric constant of the diaphragms are such that where these wave fronts are incident at a glancing angle (at P and G) they suffer reflection and result in wave fronts 9<SP>1</SP>, 10<SP>1</SP> propagating in guide 2 in the desired direction. It is shown in the Specification that the dielectric constant of the diaphragms must be small and the width a of the guide large compared with the operating wavelength # if the desired results are to be obtained over a wide, e.g. 20%, band. The material may be foamed polystyrene having a dielectric constant of 4/3 and the width of the guide may be increased up to five wavelengths. The invention may be applied to a known kind of hybrid junction in which energy incident in either of guides 24, 27 is divided by a halfsilvered mirror between guides 25, 26. Diaphragms 30-33 are located between the junction and each of the guides. In the band separation filter of Fig. 4, a multi-layer dielectric sandwich filter 39 allows one frequency channel to be transmitted to guide 37 and reflects all other channels into guide 36. The junction between guides 35 and 36 is bounded by diaphragms 40, 41.

Abstract: 821,677. Field enhanced luminescence. GENERAL ELECTRIC CO. Ltd. April 18, 1958. [April 11, 1957], No. 11936/57. Class 39(1). A zinc sulphide luminescent material, which fluoresces under a suitable exciting agency, such as cathode rays or ultra violet radiation, and from which the light output can be increased by applying an electric field across the material, is manufactured by a process which includes the steps of growing single crystals of zinc sulphide, either self-activated or containing copper and/or chlorine, and then heating the material at an elevated temperature, e.g. about 400‹C., in an evacuated enclosure. In an example, substantially pure zinc sulphide was fired in vacuo at 1000‹C. for two hours and then heated in a silica tube containing hydrogen sulphide at a pressure of 2 to 10 cms. of Hg for 3 to 6 days, the temperature gradient in the tube being 10‹C. per cm, and the hottest end of the 15cm tube being at a temperature between 1100 and 1250‹C. The resulting crystals which possibly contained minute traces of copper and/or chlorine, were then heated at 400‹C. in a silica container evacuated to a residual pressure of 10-<SP>6</SP>mm of Hg. The crystals then emitted blue light with short afterglow on excitation by ultraviolet light of wavelength 3650Š and their light output was increased by an electric field of 1000 volts per cm. A second material, produced in the same way except that the initial firing in vacuo was for only half an hour, emitted green light of relatively long afterglow under the same exciting agencies. A fieldenhanced luminescent material comprising zinc sulphide activated by manganese and chlorine is also referred to.

Abstract: 591,642. Turnip toppers and tailers. THOMSON, J. May 15, 1945, No. 12191 [Class 6 (iii)] A turnip lifting, topping and tailing-machine has a pair of shares, a pair of opposed endless belts driven from the ground wheels between which each turnip as it is raised is conveyed backwards, a topping and tailing knife which act on the turnip as it is conveyed backwards, and automatically acting means controlled by the diameter of the turnip by which said knives are raised and lowered to suit the size of the turnip. In the construction shown, the machine, which may be horse-drawn or coupled to a tractor, is provided with two ground wheels on an axle b which also carries a frame b<SP>1</SP> and a pair of frames c, each having a pair of longitudinal members d carrying rollers e, e' at each end, over which an endless band f passes, said band being driven from the land wheels through bevel gears o and p. Shares g are secured to the leading edge of the members d, and at the sides of the latter, guide members hare hingedly secured. In operation, the frames c are lowered by means of the pivotal lever q so that the shares pass under the roots at each side, and as each root is lifted it is gripped between the opposed bands f and carried rearwardly to a topping knife k<SP>1</SP> carried by a support k on guides j, the position of said knife for varying sizes of roots being adjusted through arms l, being pivotally attached to brackets l<SP>2</SP> carried by plates i<SP>3</SP>, against which the band f bears, said plates being urged inwardly by springs. The guides h carrying tailing knife m are also controlled from the spring plates i<SP>3</SP> through rods n.
