Title: Manufacture of blue dyestuff
Filed: 1925-09-17
Abstract: Pure N-dihydroanthraquinoneazine, obtainable according to Specification 184,193, is heated with concentrated sulphuric acid with or without boric acid; the product dyes cotton from the vat in shades which are brighter and faster to chlorine than those yielded by the product obtained from non-purified N-dihydroanthraquinoneazine.  The process may be modified by combining the purification of the parent dyestuff and the heating with sulphuric acid into a single operation; in the latter case the crude N-dihydroanthraquinoneazine is heated with concentrated sulphuric acid and boric acid, the mass diluted by addition of weaker sulphuric acid and the product filtered; it may be further purified by fractional precipitation from sulphuric acid.

A modification is described in which the up and downcast flues are connected in pairs, and one top opening 8 and two bottom openings 7 are provided for each pair. The walls 2 of the oven may be made of relatively thin ceramic material and may be strengthened by ties bridging the passage 9. These ties may be extensions of the header bricks, which form the partition walls between the flues 3, 4. Distillation is effected at a temperature of about 600‹ C.

Abstract: 1420303 Winches CATERPILLAR TRACTOR CO 28 May 1974 [29 May 1973] 23608/74 Heading B8B [Also in Division F2] A winch assembly has a power input shaft (14), Fig. 2 (not shown), which may be driven by the power-take-off of a tractor, driving shaft 19 through a normally disengaged input clutch (16) and gears (17), 18. The shaft 19 has a bevel gear meshing with bevel gears 22, 23 arranged on a shaft 26 and respectively coupled to clutches 27, 33. When both clutches 27, 33 are engaged by spring force the shaft 26 is locked. Disengaging one or other of the clutches enables the shaft 19 to drive the shaft 26 in one direction or the other and thus rotate winch drum 13 through a normally engaged disconnect clutch 41 and gears 42, 72, 74, 67. The disconnect clutch 41 includes jaw gear 42 arranged for rotation on the shaft 26 and fixed against axial movement by a thrust-plate 43 and a pin 44 extending from the shaft 26 into a groove 46 in the jaw gear 42. A second jaw gear 47 is splined on the shaft 26 at 48 and may move into engagement with the jaw gear 42 under the action of springs 63 and out of engagement therewith under the influence of a piston 49 when hydraulic pressure fluid is introduced into chamber 52. When disengaged the clutch 41 permits freewheeling of the drum 13 free from drag caused by the shaft 26 and associated components.

Class 38 (v) An inertia switch, which closes its contacts on the rapid change in acceleration that occurs on a crash landing but keeps them open during the accelerations and changes of acceleration of normal flight, comprises two bodies 4, 6 carrying contacts and mounted on resilient supports 8, 10 in a housing 2, the arrangement being such that when the housing is subjected to a constant acceleration, the bodies take up some such position as shown with the contacts substantially the same distance apart. In the form shown the bodies 4, 6 themselves constitute the contacts and damping may be introduced by filling the housing with fluid or by eddy-current effects. The bodies 4, 6 are of equal mass but have different moments of inertia about their axes of rotation so that when there is a sudden change of acceleration, one will move more rapidly than the other and the bodies will engage each other. Fig. 5 shows such a switch arranged so as also to be operated by distortion of the aircraft skin 48. The rods 8, 10 in this case have limited axial movement and are operated by rods 50, 52 according as the skin 48 moves up or down.
