In a surface wave aerial a rectangular waveguide 1 feeds a tapered horn 2 of length l 1 , which is continued by a rectangular portion of length l 2  The top plate of the length l 2  is provided internally with a lossy coating 3 of a layer of graphite paste (for example, 4052 ohms/ square) to absorb unwanted modes. The structure has a base 4 which is provided with grooves 5 separated by walls 6 and which is further extended by lengths l 3  and l 4 . The grooves 5 commence at the throat of the horn, increase in depth linearly from zero over its length l 1 , are of constant depth over the lengths l 2  and l 3 , and are modulated in depth over the length l 4 . The modulation may be sinusoidal, of constant or variable amplitude. When the frequency of the fed energy is varied, scanning in a vertical plane is obtained. In an aerial for operation at a mean frequency of 9À1 MHz, the corresponding free space wavelength # 0  being approximately 1À3 inches, the waveguide 1 is 0À9 inch wide by 0À4  inch high and l 1  = 5# 0 , l 2  = 8 #0 , l 3  = several times # 0 . The width of the portions l 2  l 3 , l 4  is 1À2 inches. The grooves 5 are 0À055 inch wide, and the walls 6 are 0À015 inch thick. The said grooves are 0À240 inch deep in the lengths l 2 , l 3  and are modulated with a period length L = 0À7 inch in the length l 4  ( = 50L). It is stated that a frequency variation of Œ0À1 MHz results in a beam swing of 8 degrees, 4 minutes. In another embodiment (Fig. 10, not shown) launching means for the surface wave comprises a vertical probe (10) located at a distance of 3# 0 /4 from a short-circuiting wall in a rectangular waveguide.

Filed: 1967-12-20
Abstract: 1,195,550. Endless conveyers. INTERNATIONAL STANDARD ELECTRIC CORP. 20 Dec., 1967 [22 Dec., 1966], No. 57887/67. Heading B8A. The invention relates to an arrangement for conveying sheet articles, in which they are conveyed one at a time along first conveying means (not shown) in a first direction, and are transferred into a stack in a rectangular box container 1, through one open longitudinal side in the latter, without a change in the direction of motion of the articles. The containers 1 with their stacks of sheet articles are conveyed along a second conveying means 2 in a direction at right-angles to the first direction, and the sheet articles are transferred from the containers to a third conveying means 4. They are then conveyed one at a time in a direction parallel to, and in the same sense as, the first direction, separation of a stack of sheet articles from a container being achieved with abutment means 8 which press the entire stack against a pulling-off device associated with said third conveying means, means 6a removing the container in a direction which is parallel to, and in the same sense as, the first direction. As shown, the pulling off device 4 comprises a suction belt. The abutment 8 pivots from an inoperative position (full lines) to a stackengaging position (dot-dash lines). In a modification (Fig. 2, not shown), pushers 2a of a conveyer 2 for the container 1, are extended upwardly at (9) so as to replace the abutment 8. They are able to engage the stack after the container 1 has been removed by the means 6a. An abutment 3 retains the stack during the removal of the container 1, the latter being formed with slots 5 so as to clear the abutment 3 during this operation. In a further modification (Fig. 3), the container I and its articles are advanced by pushers 2a from a platform 11 on to a vertically movable platform 10 (shown in its lower position). The stack of articles is retained on abutments 3 (which the container 1 is slotted to receive). The platform 10 then removes the container to the lower position shown, and an abutment 9 engages the rear of the stack. Articles are then removed from the stack by a belt 4. There may be a detector (not shown) responsive to a container which has less than a predetermined number of articles. The container is then removed from its normal path.

Abstract: 758,045. Optical systems. LASSUS ST.- GENIES, A. H. J. DE. March 25, 1954 [March 25, 1953], No. 8743/54. Class 97 (1). A viewing system for stereoscopic images on a lenticular film F comprises a negative lens L2 adjacent the film and a magnifying lens L1. When the film is illuminated in the direction of the arrow the action of the lenticular elements reconstructs the exit pupil of the photographing objective and produces other pupils on either side of it. The lens L2 images these pupils in a position appropriate for further imaging by the lens L for viewing purposes as the conditions require. Thus, if no transposition of left and right eye views is required both eyes require to be within the central pupil. If transposition is required, this can be achieved by arranging for the two eyes to -be at the inner margins of the lateral pupils. The constants of the viewing system are variable to suit such changes. The lens Ll is axially adjustable and the lens L2 may be similarly adjustable or may be replaced by a fixed negative lens adjacent the film and an axially adjustable positive lens. In another embodiment the lens L1 is laterally offset relatively to the film but with its axis perpendicular to the film plane, the axis of the lens L2 being inclined. The calculation of suitable lens data is explained in the Specification.
