Title: Improvements in or relating to aluminium-silicon alloys
IPC: C22C21/02
Filed: 1930-12-12
Abstract: An aluminium-silicon alloy for casting contains about 3-15 per cent of silicon, up to 0,5 per cent of titanium, and the balance aluminium.  The alloy may be made by adding titanium in the course of the electrolytic production of aluminium, for example by adding titanium oxide or titaniferous alumina to the fluoride bath, so that the reduced titanium will alloy with the aluminium, silicon being afterwards as such or as an aluminium-silicon alloy.  The Specification as open to inspection under Sect. 91 (3) (a) describes also similar alloys containing in addition some copper. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,103,493. Change-speed control. BRANDENBURGER TRAKTORENWERKE VEB. 8 Sept., 1965, No. 38476/65. Heading F2D. In a change-speed gear providing reverse ratios corresponding to each forward ratio except direct drive, if provided, a finger on a gear-shift lever is engageable in slots provided in gear-shift rods carrying the usual shift forks, or in blocks operatively connected to the shift rods, the number of slots associated with the shift-rod controlling reverse corresponding to the number of indirect forward ratios. As shown, rods 27- 29 control the engagement of first and second ratios, reverse and direct drive, rods being fast with blocks 30-32 having slots 33-36 engageable by a finger of the gear-shift lever. Axial shifting of the rod 27 to engage first or second gear aligns the slot 33 with slot 34 or 35 so that the finger can be engaged therewith to shift the rod 28 axially. The gear may be such that the rod 28 is normally in its forward drive position, shifting of rod 27 establishing first or second gear, and shifting of the rod 28 establishing first or second reverse gear. Alternatively the slots 34 or 35 may be aligned with the slot 33 when the rod 28 is in a neutral position so that axial shifting of the rod 28 in one direction establishes first or second forward gear and sliding of the rod in the opposite direction establishes first and second reverse gear. The gear, see Fig. 1, is of the constant mesh type having an input shaft 1 fast with gears 2, 3 meshing gears 5, 6 selectively clutchable to a shaft 4 by a double dog-clutch sleeve 8. The shaft 4 has a gear-wheel 13 which can be clutched thereto by a clutch sleeve 11 for forward drive, the gear 13 meshing a gear 14 clutchable to an output shaft 17. Reverse is provided by clutching a gear 19 to the shaft 4, the gear 19 meshing a gear 20 fast with a gear 21 meshing the output gear 14. For direct drive a clutch sleeve 15 is shifted to release the gear 14 and couple the input shaft directly to the output shaft 17. In a modification, see Fig. 5, for controlling a gear giving four forward and four reverse speeds, rods 37, 38 controlling first and second, third and fourth ratios have slots 43, 46 provided in blocks 40, 41 fast therewith, and a rod 39 controlling forward and reverse has a block 42 provided with slots 44, 45, 47, 48, the slots 44, 45 being aligned with the slot 43 when first or second is selected, the slot 46 being aligned with the slots 47, 48 when third and fourth ratios are selected. In a modification the slots 47, 48 are provided in a block which is operatively connected to the rod 39 instead of being fast therewith.
