Title: Improvements relating to the charging of coal, coke and other solid materials into storage chambers and the like
IPC: B65G69/00
Filed: 1932-06-23
Abstract: 400,344. Shoots. BLACKWELL, E. G., 18, Brickfields Road, Worcester. June 23, 1932, No. 17693. [Class 78 (i).] In shoots for feeding coal, coke, and other solid materials into storage chambers, a control device is provided at one end, or at each end, which causes the path of the material passing therethrough to be deflected laterally in relation to the shoot and thereby enables a slow intermittent mass movement of the material down the shoot and into the chamber to be attained. The control device consists of a hopper d which is open at its upper side and has a V- shaped base. A plate e is arranged within the hopper with gaps between its side edges and the hopper which are wider at the bottom than at the top, but this plate may be in contact with one side of the hopper. Material is fed into the upper portion of the hopper, and flows around each side of the plate e into the lower portion, and thence it passes on to the shoot b. The sides c of the shoot are tapered in order to facilitate the production of an avalanche effect. From the shoot b the material passes into a hopper g which is similar to the hopper d, and after being deflected by the plate h is delivered to the shoot f, but this shoot may be dispensed with. In a modification the shoots b, fare duplicated. In a further modification the lower part of the shoot b is provided with a grid through which fine material passes to be discharged outside the storage chamber.

Filed: 1947-07-04
Abstract: 643,679. Aerials. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. July 4, 1947, No. 17773. [Class 40 (vii)] A circular polarizer for linearly polarized incident radio waves comprises a mirror 2 in conjunction with a plurality of parallel conductive walls 1 arranged edge-on to said mirror. The spacing b is greater than half a wavelength and the dimension w/ 2  is such that during a passage to the mirror and back the component parallel to the walls undergoes a phaseshift of 90 degrees, or an odd multiple thereof, with respect to the perpendicular component. This incident energy linearly polarized at 45 degrees to the walls will emerge circularly polarized. The Specification shows that by suitable choice of the dimensions band w/ 2 , with respect to the wavelength of the radio energy, impedance mismatch on incidence upon and emergence from the mirror structure is avoided, and the system is suitable for wide band operation. Preferably the mirror is paraboloidal and the conductive walls are fixed mechanically and electrically thereto. Strengthening partition plates may be provided at right angles to the conductive walls but their spacing must be greater than that of the walls themselves. The ducts formed between the walls may be filled with low-loss dielectric.
