Title: Level adjusting mechanism for the cross-rail of a planer type machine tool
IPC: B23Q11/00
Filed: 1961-05-16
Abstract: 984,280. Planing. G. A. GRAY CO. May 16, 1961 [June 6, 1960], No. 17858/61. Headings B3B and B3L. A machine tool comprises a cross-rail elevated by screws in each of two columns, one of the screws 11 being movable axially by an adjusting nut 22 to adjust the level of the rail. The screws engage nuts which may be rotated simultaneously to raise the rail. In the machine described, however, each screw 11 is rotated by a shaft 12 and gearing 15. The level adjusting means is carried by the cross-beam 10 joining the columns and comprises a motor 34 which, through a friction drive 36 and planetary gearing 30, rotates a nut 22 engaging a threaded upper portion of one of the screws. The motor may be controlled by an automatic levelsensing device.

Title: Rotary mowers
IPC: A01D43/10
Filed: 1974-04-24
Abstract: 1515268 Rotary mowers CLAYSON NV 17 April 1975 [24 April 1974] 17866/74 Heading A1F A rotary mower 1, as described in the Specification 1515269, comprises cutter units 10 mounted for rotation on a chassis 2 comprising a transverse upper beam 3, arms 4, and supports 5 between which extends a secondary transverse beam 6 having an upturned forward edge 15. The cutter units 10 are mounted in bearings 8 on the supports 5 and bearings 9 on the upper transverse beam 3 and each comprises a shaft 11, a cylindrical body portion 14 and a flange 13 to the underside of which are pivotally attached knives 17. Below each flange 13 and positioned forwardly of the shaft 11 is a freely-rotatable mud shield 22 mounted in a bearing 21 which is secured to one of the supports 5 by means of a bearing seat 20. The mower is suspended from the three point linkage 30 of a tractor and is moveable, about the axis of the arm 32 of a pivot-crank 31, from an inoperative transport position wherein it extends behind the tractor to a working position wherein it extends transversely of the direction of tractor travel 69. Drive for the cutter units 10 is derived from the tractor PTO via the V- pulleys 54 and 56. The shaft 50 of the V- pulley 54 rotates within a hollow shaft 46 and, by means of the bevel gears 53 and 62 situated inside a gearbox 49, drive is transmitted to the cutter units 10 by a belt drive. As seen in Figure 4, a crop conditioner 80 may be located behind the cutter units 10 and comprises a framework 81, having side walls 82 and transverse beams 83 and 84, secured to the chassis 2 by mounting brackets 85, 86. Upper and lower conditioning rolls 87, 88 having cooperating rubber ribs 89 are rotatable about shafts 109 and 90 respectively. The conditioning rolls 87, 88 are rotated in opposite directions, the drive for the roll 88 being obtained from the gearbox 49 via a bevel gear 96 and the chain and sprocket system of Figure 5 (not shown) and transmitted to the roll 87 by gears 98, 100, 103 and 108. The shaft 109 of roll 87 extends through elongate holes (not shown) in the side walls 82 enabling vertical adjustment of the roll 87. Springs 110 extend between one of a number of pairs of corresponding holes 112 in the crank arms 106 and adjustable supports 111. This arrangement permits the force exerted by the upper conditioner roll 87 on the crop to be adjusted so that such force is reduced as the quantity passing through the conditioner 80 increases. Specification 1515270 is also referred to.

Abstract: 662,331. Agglutinated fibrous materials. NATIONAL RESEARCH DEVELOPMENT CORPORATION. June 8, 1949 [July 2, 1948], No. 17912/48. Class 140. Synthetic resin reinforced with fibrous asbestos is made by crushing asbestos rock in a manner whereby a mass of substantially parallel fibres is provided, then impregnating the fibrous mass with synthetic resinous material and causing or permitting the resin to dry while the fibres are still substantially parallel. Asbestos rock 11 is fed between crushing rolls 12,13, with the natural planes of cleavage substantially normal to the plane containing the axes of the rolls, the resultant substantially parallel fibres being fed between travelling copper-gauze belts 14, 15 which carry them. through a bath 16 of the material 17 with which they are to be impregnated, e.g. a partially condensed phenol - formaldehyde resin ; excess liquid is removed by the rollers 18, 19. Thin paper or other backing 20 may then be applied and the web carried on the belt 15 through a drier 21 before being stored or calendered. The sheets may be stacked and the resin cured to form a stiff material. For low-temperature curing, the fibrous masses stacked in adjacent layers may be impregnated with different constituents of composite resins, as described in Specification 658,269.

[Class 83 (i)] [See also Group X] Casting processes ; mould materials.-A porous metal backing 12 for a paving or like block or for a sand mould for casting iron rollers &c. is formed by casting metal onto a mould surface, adapted to evolve gas when heated. The mould 10, Fig. 5 or 6, may be made of cast iron or steel and be oxidized at 800 to 900‹ C. for about a week. It is initially heated to 300‹ C. and kept hot by making a series of castings. The iron is poured at 1250 to 1300‹ C. Under these conditions it is stated that gas is evolved and produces a number of bulbous recesses 14 in the lower face of the plate. These serve as anchorages for road material 18, Fig. 3, applied before or after placing on a road, or for rubber or concrete for floors or for sand in flasks. The mould 10 may be used without the oxidizing treatment if preheated to 400 to 600‹ C., but the temperature may be allowed to fall after several backings have been cast as oxidation of the mould surface will have taken place. The backing may be cast with shaped edges 20, 21, Fig. 5, to fit adjacent backings and with a hollow back 30 by using a sand top 23. Reinforcing bars 24, Fig. 6, of mild steel and anchoring lugs 25 may be cast in.
