'[Class 6(i)] Seed sowing apparatus comprises a container with a delivery opening at one side and a rotor rotatable about a transverse axis, gripping members resiliently pressed towards the surface of the rotor being successively moved towards and away from the surface to pick up seeds when passing through the bottom of the container and release them at the delivery opening. The seed container is riveted to a frame 10 having a draw-bar 11 and a shaft 12 supporting a pair of rollers 13 to close the drills made by a coulter 22 in front of the delivery channel 56 from the seed-container. A scraper 14 is provided to remove soil from the rollers. A paddle-wheel 17 mounted on a shaft 15 secured to the frame 10 is rotated by engagement with the ground and drives by a chain gear connection a shaft 27, Fig. 2, which projects into the seed container and thus rotates the seed gripping members mounted on the shaft 27. These seed gripping members consist of a number of spring blades 35 arranged radially on the shaft 27 to engage with the flat rim 40 of a dish-shaped rotor 39 loosely surrounding the shaft 27 and loosely secured by pins 44 to a driving plate 37 welded on the shaft 27. Secured to the opposite face of the rotor 39 is a plate 42 having an outwardly directed cylindrical rim 43. A roller 51 engaging with the inner surface of this rim 43 is so mounted in the container wall 25 that, by adjusting a lever 48, the rotor can be displaced eccentrically with respect to the spring blades 35. The rotor has slit openings 59 through which the seeds flow to be gripped between the rotor surface and the spring blades and carried round to the mouth of the delivery channel 56. A cam track 52 is fastened to the bottom of the seed container part of it extending beneath the rotor and another part 54 extending transversely to the first part in a vertical direction has its upper extremity 55 within the rotor. The vertical parts 54. 55 of the cam track form the rear wall of the delivery channel, closing the openings 59 in the rotor during their descent, the front wall being formed by a continuation of a side wall of the seed container. When the spring blades 35 engage the upper part 55 of the cam track they are forced away from the flat rim 40 of the rotor and any seeds gripped are released and drop into the delivery channel. As the blades reach the bottom of the cam track 52 they reengage with the rim 40 of the rotor.

Title: Improvements in or relating to sheathed headed articles, for example poppet valves, and methods of making the same
IPC: F01L3/14
Filed: 1944-09-15
Abstract: 586,934. Brazing. STEVENS, A. H. (Thompson Products, Inc.). Sept. 15, 1944, No. 17701. [Classes 83 (ii) and 83 (iv)] [Also in Group XXVII] Making valves.-A poppet valve or other headed member comprises a body with stem and head portions 22 made of stress-resisting material such as alloy steel and a corrosionresisting head sheath 13 brazed to the head by material 14, and having its periphery connected to the head by a metal bond 23 which also seals the brazing material. In one form, a solid metal billet 10 with a reduced head 11, Fig. 5, is covered first with a thin disc 14 of copper, silver or other brazing metal and then with a cap 13 of corrosion and heat-resisting material such as an alloy of 80 per cent nickel and 20 per cent chromium. The disc may be cupped to fit over the part 11 by the action of pressing on the cap 13 so that the brazing material covers the entire inner surface of the cap. In some cases the bonding metal may be electro-plated on to the cap 13 and part 11. The assembly is heated in a hydrogen atmosphere to effect the brazing of the cap and a groove 17 cut at the edge of the cap. The billet is then die pressed and extruded to form the hollow stem, Fig. 7, with an enlarged end 22a. The groove 17 is then filled with the sealing bond 23 which may be of the same material as either the cap or the valve body, forming a bead which is subsequently ground off to form the finished head. The stem is finally filled with a coolant such as sodium and the end 22a swaged to form a closed end. In a modification, the sealing bond 23 may be made before the die pressing and extruding operations. In another modification, a solid forged valve body 42, Fig. 12, has a groove 44 machined in the under surface of the head which is then electro-plated with brazing-metal. A cap 45 with a similarly electro-plated inner surface is then placed over the head and spun over the face of the valve seating, Fig. 13, the groove 44 being finally filled with the sealing bond 47 which is ground off flush with the neck 42. A similar process may be used for making hollow valves.
