Title: Collapsible portable boat and its method of assembly
IPC: B63B7/04
Filed: 1971-09-13
Abstract: 1357945 Collapsible boats D TANABE 13 Sept 1971 [15 Feb 1971] 42566/71 Headings B7A and B7S A boat comprises a hull made by folding a single or double sheet of material and a stabilizer made by folding a further sheet of material. The stabilizer is permanently secured to the hull to provide open ended water passages between the stabilizer and the bottom of the hull. The boat is collapsed by folding. As illustrated, the hull is formed from two superimposed rectangular sheets of plastics material which are folded in the manner shown in Fig. 2 to provide a square ended hull which is held erect by the insertion of reinforcing members 41. The sheets are laterally staggered so that at each side of the boat the edge of one sheet can be folded over and secured to the edge of the other. Each sheet of material has two plane layers and an intermediate corrugated layer, the corrugations running along the boat. The stabilizer is folded from a single sheet of material with its corrugations running across the boat as shown in Fig. 3. The stabilizer is secured to the sides of the hull by riveting and welding and to the bottom of the hull by adhesive. Rubber rowlocks 42 are added. The boat is collapsed by removing the reinforcing members 41 and then pulling the ends of the hull outwards so that the sides fold on to the bottom. The boat is then folded about its longitudinal centre line. In another embodiment, Figs. 8-12 (not shown), the hull has a rounded bow and a square stern, and the passage forming parts of the stabilizer extend both downwardly and outwardly from the hull to give increased stability.

Abstract: 1,078,726. Rolling. DEMAG A.G. Nov. 6, 1964 [Jan. 7, 1964], No. 45419/64. Heading B3M. A rolling mill which is convertible between two- and three-high working, incorporates different roll driving arrangements for each condition. For three-high working, suitable for rolling narrow strips, the lower working roll 2a is driven from a main motor shaft 10 through a shaft 12 and coupling 5b, while the backing roll 2c is driven from a motor 17 through gearing 16, 15 and a coupling 6b. The working roll 2b is frictionally driven by the roll 2c, the motor 17 serving to speed up or slow down the roll 2c and hence the working roll 2b without producing any rolling power. For 2-high rolling, suitable for producing rods, the heavier driving loads are met by driving the upper rolls using a pinion 9 in mesh with a pinion 7 on the shaft 10, the clutches 14 and 18 being appropriately engaged or disengaged for the two systems. Planetary, or bevel gears 15 and 16 may be employed.
