Title: Improvements in cultivators
IPC: A01B63/26
Filed: 1919-12-05
Abstract: 159,636. Martin, W. E. Dec. 5, 1919. Cultivators.-A cultivator is provided with hand-operated means for raising one or both sides of the tine-carrying frame and also with means operated from the main wheels for raising the whole frame for transport. The tinecarrying frame d is carried on each side by one part f of a divided shaft, this shaft on each side being connected to a pin on a strap around an eccentric g<1> pivoted on the main shaft b. Arms h extending upwards from the parts of the divided shaft are connected to links j, j<1> extending forwardly alongside each other. The link j<1> is adjustably connected to the link i through a hand-lever l<1> and rack quadrant i. The link j is adapted to be drawn forward, thus turning the divided shaft round its connections with the eccentric straps and so raising the tines, by a hand-wheel k<2> operating a screwed shaft k<1> passing through a nut k on the link. A spring k<4> cushions the pressure of the hub of the hand-wheel against the frame. The screwed shaft and hand-wheel are free to move longitudinally should the tines strike an obstacle and rise. The fore part of the cultivator frame is hung by a chain m from the stem c<1> of a forward castor wheel c, this chain passing under a pulley m<1> on the tine frame and extending rearwardly over a pulley m<2> secured to an upwardly extending portion of the tine frame and being attached finally to the bearing for the shaft b. The rise or fall of the rear end of the tine frame thus causes a corresponding movement of the forward end. The lever l<1> and the hand-wheel k<2> are arranged at the front of the cultivator so that they may be operated by the tractor driver. The lift of the tine frame from the main wheels is given by the driver pulling-over a lever n<@> uperating through a link n<5> and cranked cross-bar n<4> spring-controlled rods carrying rollers n<2> normally in the path of stops n<1> on pairs of discs, one of each pair of discs being secured to an eccentric g<1> and the other disc being pivoted to the first disc but normally urged by a spring to move forward relative to said disc. On operating the lever and removing the rollers from the stops, the second discs move forward, causing pawls on the eccentrics to engage teeth on the wheels, thus rotating the eccentrics After moving through 180 degrees, a second set of stops on the discs engages the rollers and brings the eccentrics to rest, the pawls being freed as the second discs are forced back. The next pull on the lever n<6> causes the eccentrics to move to their low position bringing the tines into operation again.

Abstract: 1,022,776. Photo-electric turbidometers. UNION CARBIDE CORPORATION. Aug. 4, 1964 [July 24,1963; May 6, 1964], No. 30749/64. Headings G1A and G1X. The presence of a relatively non-volatile substance in a volatile solvent is detected when the mixture is atomized and the solvent evaporated away leaving the non volatile substance appearing as a fog, which by scattering a light beam actuates a photo-cell. In one arrangement shown in Fig. 1 the liquid mixture is introduced into a gas stream for atomization by a needle-valve and the heater 7 causes evaporation of the solvent in the chamber. The resultant fog of the substance scatters the direct light from lamp 8 and the indirect from reflector 9 which is received by photo-cell 10 connected in a bridge circuit. A light trap 1 provides an exit for the gas stream. In another arrangement (Fig. 3 not shown) the reflector is absent and two lamps with collimating slits send beams in a horizontal plane, normal to the vertical plane of the gas stream, to be received by the curved light traps. The atomised stream may be further directed in the chamber by conical guides and heated by using heated gas. An improved liquid inlet jet is described (Fig. 6 not shown). In all the arrangements the intensity of the fog and hence the amount of light received by the cell indicates the concentration of the substance in the solvent.
