Title: Improvements in cultivators
IPC: B62D51/04
Filed: 1920-05-19
Abstract: 167,609. Wilson, D. K. May 9, 1920. Cultivators; ploughs.-In a motor-cultivator in which a ploughshare may be substituted for one of the cultivating-tools, and in which the frame is mounted on main wheels and castor wheels, interconnected manually-operated appliances are provided for moving the cultivating-tools and steering the main wheels, either separately or conjointly, and aLso for alternatively locking the steering-mechanism while the castor wheels are free to castor or locking the castor wheels while the steering-mechanism is free. The main wheels 84 are driven by chain gearing from a shaft 85, which is driven by chain and differential gearing from the motor (not shown). A friction clutch 60 connected with the differential gearing is operated by means of a rod 53, bell-crank 55, sleeves 58, and links 59. The cultivating-tools 13 are adjustably mounted on tubes 11 clamped on rods 9 which are hinged to swivelling members 8. The rear parts of the rods 9 are hung from steering-rods 17 in such a way that the rods 17 may be moved longitudinally without moving the rods 9. The rods 17 terminate rearwardly in adjustable handle-bars 79 and are universally iointed at their front ends to a centrally pivoted bar 19 provided with a toothed segment 20 gearing with a toothed segment on a bar 22 which is pivoted at 23. Arms 25 project from the bar 22 and are connected together by a plate 31 to which a bent cross-bar 50 is pivoted. The bar 50 carries vertical spindles about which castor wheels 49 are adapted to swing. Arms 44 projecting from the tubular standards of the castor wheels 49 are jointed to a bent connecting-bar 42. The wheels 49 are normally prevented from castoring by the engagement of a bar 37 with a notch in an angle plate 40 on the connecting-bar 42. The bar 37 is pivoted on lugs on the plate 31, and is connected by arms 35 and rods 91 to a cam-plate 27 mounted on the arms 25, so that when the bar 37 is raised to release the castor wheels for turning the implement round, the plate 27 is drawn backward into engagement with rollers 29 on a fixed cross-bar 4 so as to lock the bar 22 rigidly to the frame 1. The cultivator is normally steered by moving the rods 17 longitudinally, and the tools 13 raised or moved laterally by swinging the rods 17 vertically or laterally. Steering the cultivator and adjusting the tools may be effected separately or simultaneously. Hooks are provided to hold the rods 17 in inoperative position. The right-hand castor wheel 49 mav be adjusted laterally when a ploughshare is used.

Abstract: 1462339 Fluorophosphoric acid tetramethyldiamide WACKER-CHEMIE GmbH 7 April 1975 [19 April 1974] .14078/75 Heading C2P Fluorophosphoric acid tetramethyldiamide, a known systemic insecticide, is prepared by reacting liquid phosphoric acid tris(dimethylamide) with solid ammonium fluoride at a temperature not less than 140‹ C. The reaction is preferably carried out under atmospheric pressure and using a mole ratio of tris(dimethylamide) to fluoride of from 1 : 1 to 1À6 : 1. The process may be carried out semi-continuously by continuously adding the tris(dimethylamide) to the fluoride while distilling off the product or continuously by continuously adding a mixture of the reactants to a reaction vessel while distilling off the product. The tris(dimethylamide) may be added in the form of a solution in the solvent in which it is prepared, the solvent being distilled off from the mixture of starting materials before the reaction and the dimethylamine by-product being dissolved in the solvent that has been distilled off. When an excess of tris(dimethylamide) is used the product may be mixed with unreacted tris(dimethylamide) and such mixtures may be used directly as insecticides.

Further rolling followed during cooling in 15-20 passes down to a plate thickness of 1À5 mm. Alternatively, thicker plates (up to 8 mm.) were reheated to 850-900 C. and again hot-rolled, with intermediate heating at 870 C., down to 3À5-1À75 mm. Warm-rolling followed, and then cold-rolling down to below 1 mm. Plate thicknesses down to 0À03 mm. are referred to.

Abstract: 141,312. Sterling Telephone & Electric Co., and Davey, W. C. Dec. 31, 1918. Drawings to Specification. Automatic exchange systems.-Single-stroke bells are used at the subscribers' stations, and are rung by an interrupter in series with a source of direct current. The same or another interrupter may be used to notify the calling subscriber, by ringing his bell or producing a buzz in his receiver, of the successful progress of his call after each digit has been transmitted. The ringin in terrupter is designed to break the ringing-circuit only momentarily, so that if a third subscriber obtains connexion with a subscriber who is being rung, the ringing potential on the called line prevents the establishment of the connexion by the third party. The systems described are identical with the corresponding systems described in Specifications 141,106. Specification 141,311 also is referred to.

Stops 4a at the ends of the support member 4 limit movement of the guide 2 whereafter further movement of the cable causes sliding thereof along the guide 2. Both the support member 4 and the guide 2 are formed as channel members, open in a direction radially outwardly of their curvature. Each resilient pad 6 comprises alternate layers of elastomeric material and metal plate offering greater shear resilience than compressive resilience. In the embodiment of Fig. 5, a hollow frustoconical support 24 supports through circumferentially special resilient pads 6, an inner hollow guide 26 having a convex inner circumferential surface for engaging the cable, axial movement of the guide 26 being limited by an upper stop 24a integral with the support 24, and a lower removable stop (not shown), facilitating disassembly of the fairlead. In this embodiment the circumferentially spaced resilient pads may be replaced by resilient pads of annular form.
