Abstract: 1,099,528. Moulding fibrous materials. FORMWOOD Ltd. Feb. 26, 1965 [March 7, 1964], No. 8396/65. Heading B5A. Contoured plates are made from comminuted fibrous material, e.g. wood chips, and a binder within a mould 13, the material being delivered from a distributor to the mould apportioned by density and quantity to conform with the desired moulding. Material 1 is fed by a conveyer belt 3 to a shaping roller 2, to brush rollers 4, see also Figs. 2 and 4 (not reproduced), and then falls into a weighing device 5. From thence the material encounters further brush rollers 9, 10 and a shaping roller 6 and is accelerated into the mould by an impact roller 8. The shaping rollers 2 and 6 may be grooved or have radially adjustable pins. To produce longitudinal variations in the thickness of the plates these rollers may be smooth and vertically adjustable or be replaced by vertically reciprocable plates. The brush roller may also be adapted to perform a shaping action and additional distributing devices such as diaphragms and suction devices may also be incorporated. The mould 13 may be moved at a uniform speed or intermittently beneath the distributer. Reinforcing material may be incorporated.

Abstract: 1458612 Maize harvester RIVIERRECASALIS 25 Feb 1974 [2 March 1973] 8452/ 74 Heading A1F A maize or corn harvester for an ensilaging machine comprises two dividing members 56, 57 between which two rotating blades 16, 17 cooperate with a stationary blade 18 for cutting of the stalks, the rotating blades being driven via two chains 12, 13 which pass around sprockets 14, 15 disposed above and coaxial with the blades. On the chains are mounted fingers 12a, 13a, these serve to pull the lower ends of the cut stalks rearward towards feeding rollers and a cutting rotor (not shown). Each rotating blade 16, 17 has three cutting edges disposed so that alternate blades engage with the stationary blade 18. Each set of blades and sprockets are mounted upon a shaft (not shown) extending forwardly and upwardly within members 56, 57; at the top of each shaft is mounted a rotary member 7, 8, these cooperate with each other and with spring biased stop elements 10, 11 to pull the upper part of the stalks rearward and to retain them, thereby preventing their retreat prior to outting. The rotary elements 7, 8, are designed with fewer limbs 7a, 8a than the rotary blades 16, 17 so that although they rotate at the same rate, the lower part of each stalk is caused to move rearward at a faster rate than the upper part, thereby ensuring that the stalks approach the feed rollers bottom first. In an alternative embodiment, the sprockets 14, 15 may be rotaltably mounted upon their respective shafts, the latter being driven independently.
