IPC: A01D34/49
Filed: 1970-09-11
Abstract: 1,264,748. Safety flap for rotary lawn mowers. VICTA Ltd. 11 Sept., 1970 [8 April, 1970], No. 43578/70. Heading A1F. [Also in Division F2] A safety flap 4 is pivotally attached to the discharge port 5 of a rotary lawnmower by a rod 7, and over-centre locking means, actuated by a lever 11, are provided to hold the flap in an open or closed position. The lever 11 is pivoted at 12 and carries one end of an arcuate spring 13 the other end being anchored at 15 in the flap 4. The ends of the spring 13 are such that they tend to draw together. The lever end of the spring 13 is folded back on itself round a pin 14 to form an auxiliary spring 25 with an inturned tongue 26, and the lever 11 is provided with a stop 21 to limit the pivoting of the spring about 14. A catcher (6) (Fig. 2, not shown) can be secured to the mower by engaging pins (17) with hooks 18 on the mower handle 19. When the lever 11 is moving forwards, the flap 4 is pulled upwards by the tension of the spring 13, thereby closing an aperture (20) on the top of the catcher and opening the discharge port 5. To ensure efficient operation, an auxiliary leverage device is incorporated consisting of a projection 24 on the top 8 of the discharge port 5 which engages with the auxiliary spring 25. When the catcher (6) is removed, the tension in the spring 13 draws the flap 4 up to a higher elevation where the point 15 passes to the upper side of a line between 12 and 24 and serves to unlock the lever 11. The weight of the flap 4 pulls the lever over towards the rear of the mower and the flap moves to its closed position, the closing assisted by a torsion spring 7A on the rod 7. Residual tension in the spring 13 abutted against the stop 21 applies a force between the anchorage 15 and pivot 12 which will keep the flap 4 shut against the action of the air blast from the blades and the impact of objects thrown up by the blades.

Abstract: 1296198 Growing whisker-like crystals PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 29 Jan 1970 [1 Feb 1969] 4360/70 Heading C1A Crystals in the form of whiskers, having an average thickness up to 100 millimicrons (mÁ) and a length at least 10 times larger than the thickness, are grown from a gaseous atmosphere containing the crystal material (or reagents which react to form the crystal material) on the surface of a substrate which is uniformly rough due to projecting crystallites, the lateral dimensions of which approximately correspond to the thickness of the whiskers to be grown. In an example, a plate formed by sintering silicon carbide powder is dusted with iron powder, having a grain size smaller than 1 mÁ, and is placed in a bed of quartz powder in a graphite crucible which is heated at 1280 C. in a quartz tube through which hydrogen is passed. Whiskers of silicon carbide, of diameter 1 mÁ and length 20 mm., grow on the plate in 10 hours. In another example, tablets 11 of compressed aluminium oxide powder, having a grain size of 0À01 to 0À1 mÁ, and alumina crucibles 12 filled with aluminium 13 are placed on a bed of quartz grains 14 in an alumina boat 15. The assembly is surrounded by an alumina tube 16 through which hydrogen is led, and heated at 1300 C. Crystallites of aluminium form on tablets 11, and ribbon-shaped aluminium oxide whiskers grow thereon. Other examples relate to the production of whiskers of silicon nitride, and of silicon.
