Filed: 1925-05-26
Abstract: 249,368. Budd Wheel Co., (Assignees of Nelson, E. A.). April 9, 1925, [Convention date]. Rolling.-Means for supplying blanks to and removing them from machines is described with reference to manipulating discs in wheel-rolling mills. A blank 15 with a central hole is inserted by hand between a forked plate 11 and a spring-pressed centering pin 14. The plate 11 is mounted on a three-bar frame 18 provided with rollers 21 to slide in grooves 24 of trackways 22 secured to columns of the machine. The frame 18 carrying a blank is slid forward by hand until the fork of plate 11 engages with the centering pin 33 of the work-rotating table B, when the forward pair of rollers 21 of the frame 18 drop down a vertical groove 25 thus tilting the frame and dropping the blank over the pin 33, on to the table. Pin 33 pushes up the pin 14 out of the central hole and the frame 18 is withdrawn by hand, the dropped rollers 21 now travelling in the lower of the grooves 24 until they come to inclined switch grooves 26 whence they mount to the upper groove 24 and the frame becomes horizontal again and is ready to receive another blank. The table B is then automatically moved vertically and rotated while pressed against two rollers traversing from centre to outside as described in Specification 250,521. The finished disc is removed by the frame 18 shown on the left, which slides in grooves 24 and is pushed by hand towards the disc, so that the plate 11 squeezes itself between disc and table until its forked end comes against the pin 33. At this point an adjustable dog 48, Fig. 4, releases a trigger 45 so that a spring 41 pivots the arm 38 until its end tube 34 descends over centre pin 33. At the same time the outer rollers 21 of the frame 18 drop through a vertical groove 25 thus tilting the frame &c. and raising the disc clear of pin 33. The frame with disc is now slid back the outer rollers 21 moving in the lower groove 24 until they are raised by an inclined switch groove 26 to the upper groove 24. Pressing on the handle 50 removes centering pin from the disq and resets the trigger mechanism while the disc is removed by hand from the plate 11.

Filed: 1955-05-13
Abstract: 769,165. Aerials. STRAUCH, R., ALLEZARD, R., and MENU, J. May 13, 1955 [May 15, 1954], No. 13850/55. Class 40(7) An aerial for the radiation of circularly polarized waves comprises a flat circular disc excited, at a plurality of points distributed round a circle on one of the faces of the disc, by wave energies having respective phase differences equal -to the angular distances apart of the points to which they are applied. The aerial gives a substantially circularly polarized field over a wide beam angle. As shown, the circular disc 12 is mounted inside a dielectric housing 2 at the end of a metallic support cylinder 1. The coaxial feed 3 is led into the cylinder 1 at the opposite end to the disc 12 and is coupled to a cavity 5. Leading from the cavity are N equi-angularly distributed coaxial lines the extensions of whose inner conductors (7, 9) couple them tc the cavity. The diameters of the cavity and coupling probes are arranged to be such that energy from the input is entirely transmitted to the N coaxial lines. These lines extend through the centre part of the cylinder 1 and their inner conductors (7<SP>1</SP>, 9<SP>1</SP>, 10<SP>1</SP>) extend beyond into the dielectric housing 2 and are connected to the disc 12 at N points spaced round a circle. The N lines in the centre part of the cylinder are filled with varying lengths of dielectric to establish the required phase differences. The dielectric material is preferably arranged in pieces 14 all but one of which in any line is of a length which is a multiple of a quarter wavelength. The extensions 7<SP>1</SP>, 9<SP>1</SP>, 10<SP>1</SP> of the central conductors of the N coaxial lines each serve as an impedancematching transformer and their length and diameter are determined experimentally to effect impedance match. Twice the diameter of the disc 12 less the diameter of the circle around which the points of excitation are arranged should be approximately half of the working wavelength. A metallic ring 15 screwed to the cylinder 1 is provided to eliminate back radiation. Specifications 567,201 [Group XL] and 650,622 are referred to.
